ARCHITECTURAL SYSTEM OF INTERIOR MODULAR CONSTRUCTION
Abstract
An architectural system of modular construction for building
structures including floor and ceiling rails or stringers forming
rectangular floor and ceiling sections in vertical alignment with
one another, pedestals adapted to be supported on a structural
concrete floor for supporting the floor rails, suspension rods
adapted to be hung from a structural concrete ceiling for
supporting the ceiling rails and vertical cornerposts which may be
erected at the corners of any of the vertically aligned floor and
ceiling sections to extend between the floor and ceiling rails.
Panels for the floor and ceiling are supported in the same plane as
the floor and ceiling rails. Thus the panels are disposed adjacent
the rails, and do not overly the rails. Partition wall panels may
be mounted between the erected corner posts in abutting relation
with the floor and ceiling rails for selective partitioning of the
floor and ceiling sections. The pedestals are adapted for vertical
adjustment from above the floor line without removing the floor
panels and the cornerposts and partition wall panels can be erected
and removed without interference with the floor and ceiling rails
and panels to provide for a highly flexible and easily altered
modular construction.

Description
BACKGROUND OF THE INVENTION
This invention relates generally to the field of building
construction and more particularly to interior modular construction
in which the architectural system is adapted to enable the floor
plan and interior arrangement of a given space to be easily and
quickly modified to accommodate changes in use and occupancy
requirements of the building structure.
Numerous floor systems, movable partition systems and suspended
ceiling systems are known in the prior art. Some of the systems
permit modification of the floor plan of the building structure
without substantial modification of the floor system while in other
instances the partition walls, doors and the like can be rearranged
without substantial modification of the ceiling system. None of the
known systems, however, are adapted to provide complete flexibility
and extensive modification of the floor plan without any
substantial modification of either the floor system or the ceiling
system.
SUMMARY OF THE PRESENT INVENTION
The present invention integrates a floor system, a movable
partition wall system and a ceiling system into a single system of
modular construction which provides an access floor, a suspended
ceiling and an arrangement for removable partition wall panels,
doors, windows and the like which can be erected and removed
without any interference with or modification of the floor or
ceiling.
Briefly, the architectural system of the present invention
comprises a network of floor and ceiling rails or stringers which
are supported respectively above and below a structural concrete
floor and ceiling and arranged in a crisscross or checkerboard
manner to provide a plurality of rectangular floor and ceiling grid
sections that are in vertical alignment with one another and which
extend completely across a given space. The floor and ceiling rails
include a first series which extends horizontally and in end-to-end
relation in one direction in spaced parallel columns and a second
series which extends transversely of the first series in spaced
parallel rows.
The floor rails are supported on floor pedestal assemblies which
are adapted for aligned placement on the structural concrete floor
below the floor rails and at the corners of the floor sections so
that each pedestal supports the ends of the four floor rails which
come together at a corner of a floor section. Floor panels which
may include vacuum outlets, piping slots, flush electrical outlets
and the like are placed between the floor rails in each floor
section and are supported along their edge portions on horizontal
flanges which project from the floor rails. The pedestals are
constructed and arranged for vertical adjustment after all of the
floor panels have been placed in position so that the final
elevational adjustments of the floor system can be made much more
easily and quickly as the installers stand on the floor panels.
The ceiling rails are suspended from vertically adjustable rods
hanging from the structural concrete ceiling. Ceiling panels which
may include lighting fixtures, air conditioning fixtures and the
like are disposed between the ceiling rails in each ceiling section
and are supported along their edges on horizontal flanges
projecting from the sides of the ceiling rails.
After the floor and ceiling systems have been completely installed
the space can be partitioned in any manner desired. Assume, for
example, that the space between one of the vertically aligned floor
and ceiling sections is to be enclosed for use as a small office.
Partition wall cornerposts are erected at the four corners of the
floor and ceiling sections. This is undertaken without the removal
of any of the floor or ceiling panels due to the improved features
of the floor and ceiling systems of the present invention. Next the
movable wall panels, door frames and the like are mounted between
the cornerposts as desired. The entire operation is quite simple
and requires only minimum expenditures of time and labor. The
removal of the wall panels and cornerposts is an equally simple
operation and the flexibility in any floor plan and the number of
uses to which any space can be put are greatly enhanced by means of
the present invention. The provision of these and other advantages
is an important object of the present invention.
Other objects are to reduce the costs of interior modular
construction, to standardize components of such construction, to
render modular construction more desirable in terms of providing
improved lighttight seals and noise barriers between partitioned
spaces and to reduce the time, inconvenience, expense and skills
necessary in the rearrangement of floor plans.
These and other objects, advantages and features of the present
invention will become manifest to those versed in the art upon
making reference to the detailed description which follows and the
accompanying sheets of drawings, in which preferred structural
embodiments incorporating the principles of the present invention
are shown by way of illustrative example only.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates pictorially a portion of a building structure
indicated generally at reference numeral 10 in which is installed a
system of modular construction embodying the principles of the
present invention. The building structure 10 includes a structural
floor 11 and a structural ceiling 12, both of which may be
constructed of concrete or steel beams or the like. The building
structure 10 may be multistoried, in which event the structural
concrete floor 11 may also serve as the structural concrete ceiling
of the story below, and the ceiling 12 may also serve as the
structural concrete floor of the story above.
In the embodiment illustrated the building structure 10 includes an
area 13 separated from another area 14 by means of a wall 16. The
two areas 13 and 14 may be used for the same or different purposes.
For example, area 13 may be used as office or laboratory space,
whereas area 14 may be used as corridor space.
An architectural system of interior modular construction which is
constructed in accordance with the principles of the present
invention and which is indicated generally at reference numeral 17
is installed in area 13 to enable the entire area to be partitioned
in any manner desired in accordance with the uses to which the area
is to be put and the requirements of the occupant. For example, it
may be desirable to partition area 13 into a number of private
offices, some larger than others. On the other hand the
architectural scheme and floor plan may require the provision of
some private offices along with larger rooms such as meeting rooms,
conference rooms, reception rooms, etc.
By way of contrast, area 13 may be intended to serve as laboratory
space. In some instances a number of laboratories of different
sizes may be desired. In any event, one general requirement,
regardless of the use to which the area 13 is to be put, is that
each of the various modules into which the space is partitioned or
into which it can be partitioned in the future includes means for
providing proper lighting, heating and air conditioning, electrical
power telephone wiring facilities, thermostatic and humidity
control devices and piping for liquid or gas fluids. Otherwise very
definite limitations would be placed on the flexibility and
alterability of the partitioning and use of the space.
As the description of the present invention continues, the
advantages of this system over systems presently known will become
manifest, particularly since the present system affords maximum
flexibility and the capability of being used in connection with the
partitioning of any interior space susceptible of modular-type
construction.
The system of modular construction indicated at reference numeral
17 may be more particularly characterized as comprising a floor
system 18, a ceiling system 19 and a partition wall system 20. The
floor system 18 is raised above the structural concrete floor 11 to
provide a utility space or plenum therebetween. This space may be
used to house electrical conduits running to the various modules
and corner posts, water and other piping, sheet metal air ducts,
etc. The ceiling system 19 is suspended below the structural
concrete ceiling 12 and in the space above the ceiling system 19
may be mounted lighting fixtures, heating and air conditioning
apparatus and duct work, etc.
The floor system 18 includes a grid system of floor rails or
stringers which includes a first series of rails indicated, for
example, at reference numerals 21 and a second series indicated at
reference numerals 22. The rails 21 extend horizontally in
end-to-end relation in spaced parallel columns whereas rails 22 are
disposed in rows extending transversely of the rails 21.
Structurally, rails 21 and 22 are preferably identical to one
another and may be of extruded aluminum or the like material. An
area as indicated at reference numeral 25 which is bounded by four
of the floor rails may be defined as a floor section. All of the
floor sections 25 are preferably of the same size and square shaped
whereby a high degree of uniformity of the various components which
comprise the present invention is attained. The ends of the floor
rails 21 and 22 come together at the corners of the floor sections
25 and are supported at the corners by a plurality of floor
pedestal assemblies indicated at reference numerals 23.
The ceiling system 19 is constructed complementarily to and in
registry with the floor system 18. Included is a grid system of
rails arranged in a crisscross or checkerboard manner similar to
the arrangement of the floor rails 21 and 22 and which comprises a
first series of ceiling rails 24 which extend in one direction and
a second series indicated at 26 which extend transversely of the
first series. The ceiling rails 24 and 26 form ceiling sections 27
of the same size as and in vertical alignment with the floor
sections 25. Thus the ceiling rails 24 are disposed directly above
the floor rails 21, and ceiling rails 26 are directly above the
floor rails 22.
The ceiling rails 24 and 26 are supported at their ends by a series
of suspension rods indicated at 28. The suspension rods 28 are hung
from the structural ceiling 12 by a suitable mounting arrangement
illustrated in other figures of the drawings, particularly FIGS.
14-16.
Referring now to FIG. 2, each of the floor pedestal assemblies 23
comprises a base 29 supported on the structural floor 11.
Structural adhesive may be applied between the base 29 and the
structural concrete floor 11 as indicated at reference numeral 29a
to hold the pedestal in place on the concrete floor.
Each assembly 23 also includes a vertical member such as a pipe 29b
secured to the base 29, a tubular coupling 29c threaded to the pipe
29b and a collar 29d threaded on and then welded in fired assembly
to the coupling 29c and having a radial shoulder or flange 30
abutting an upper end 31 of the coupling 29c.
The base 29, the pipe 29b and the collar 29d are hollow to enable
electrical conduit or the like to be run up through the floor
pedestal assembly 23 from the utility space below the floor system
18 to a point thereabove, and for this purpose an opening 32 may be
formed in one or more of the slides of the pedestal base 29.
Referring to FIGS. 2, 3 and 4, a floor rail connector 33 is
supported on the collar 29d and comprises a tubular member 34 and a
threaded bushing 36 secured to the tubular member 34 by means of a
plurality of setscrews as shown at 37 and threaded at an upper
portion 38 thereof.
The floor rail connector 33 further comprises four pairs of
horizontally extending fingers indicated at reference characters
41a and 41b-44a and 44b. The fingers of each pair extend in spaced
parallel relation from the tubular member 34 and the four pairs are
spaced circumferentially at 90.degree. angles from each other. The
height of the fingers are substantially equal to the height of the
floor rails 21 and 22 to rigidify and to prevent twisting of the
floor rails about their longitudinal axes.
The adjacent ends of the floor rails 21 and 22 are supported on a
top wall 46 of the floor rail connector 33. As noted, the floor
rails 21 and 22 are identical, and as shown in FIG. 8, are of a
generally inverted U-shaped configuration having a top horizontal
wall 47 and a pair of spaced parallel sidewalls 48 and 49 extending
downwardly from the top wall 47. The distance between sidewalls 48
and 49 is sufficient to accommodate a pair of connector fingers
such as 41a and 41b as illustrated in FIG. 4. The fingers thus
prevent lateral movement of the floor rails 21 and 22 and in
addition perform a supporting function for the rails.
The floor rails 21 and 22 further comprise a pair of vertically
raised ribs 50 and 51 which extend along the longitudinal edges of
the top wall 47. A pair of flanges 52 and 53 are situated below the
top wall 47 and project horizontally away from the sidewalls 48 and
49 to support respectively an edge of a floor panel as indicated at
reference numeral 54 in FIG. 1. Referring to FIG. 4, the adjacent
ends of the floor rails 21 and 22 are beveled to form miter joints
56, as a result of which the floor rails are further maintained in
snug locking relation with one another. The ends of the floor rails
21 and 22 are fragmentally circularly shaped as shown at 57 to
define with one another a circular bore 57a.
FIG. 3 illustrates the arrangement of a floor pedestal assembly 23
and the floor rails supported thereby at the corner of a floor
section 25 which is not equipped with a cornerpost, one of which is
indicated at reference numeral 58 in FIG. 1. In this arrangement a
flush cap plate 59 is threaded into the bushing 36 to provide a
flush surface 59a with the top of the bushing 36. A layer of tile
or the like as indicated at 60 is laid between the ribs 50 and 51
and is flush to the bushing 36. The tile is also laid on the floor
panels 54 to provide a completely level floor line 61.
The supporting height of the floor pedestal assembly 23 can be
adjusted from above the floor line 61 with the floor panels 54 in
place. For this purpose a square-shaped or other noncircularly
shaped bore 62 is formed in a top wall 63 of the collar 29d to
accept the complementarily shaped working end of a tool such as a
wrench or the like for threading the collar 29d and therefore the
coupling 29c up or down on the pipe 29b. The plug 59 is, of course,
removed during such adjusting or leveling operation and itself may
comprise a pair of cross-slots, one of which is indicated at
reference numeral 64, for facilitating removal by means of a
suitable tool.
As noted, FIG. 3 shows the arrangement of the upper end of a
pedestal assembly 23 when a cornerpost 58 is not installed thereon.
FIG. 2, however, illustrates the same arrangement with a cornerpost
installed. Therefore to FIGS. 2 and 6, where it is desired to erect
a post 58 at the corner of a floor section 25 the plug 59 is
removed and a post mounting plate indicated at reference numeral 66
is placed between the ribs 50 and 51 of a pair of longitudinally
aligned floor rails 21 or 22. A pair of threaded studs 67 and 68
project upwardly from the plate 66 and a threaded bushing 69 is
sized to extend through an aperture 70 for threading into the
bushing 36. A nut 71 is threaded on the bushing 69 to hold the
plate 66 tightly in place and to secure a gasket 72 between the nut
71 and the plate 66.
Referring to FIG. 9, the corner posts 58 are generally square
shaped in horizontal cross section and include sidewalls 76 and
arrowhead-shaped projections 77 at the corners of the sidewalls. A
groove 78 having a pair of spaced parallel sidewalls 79 and 80
extends along the length of each of the sidewalls 76. The
oppositely facing surfaces of walls 79 and 80 have a series of
vertical lands and grooves formed therein as indicated at reference
numeral 81 to provide a continuous threaded screw groove for
receiving a complementarily threaded screw or the like fastening
member at any point along the length of the sidewalls 76 of the
centerposts 58. The projections 77 are adapted to receive
therebetween flexible plates or the like members which can be used
to support a variety of articles and members from the cornerposts.
Such flexible plates may be adapted to slide along the length of
the post 58 between a pair of arrowhead projections 77 but can be
locked against movement at any point along the post by means of a
suitable fastener threaded into one of the grooves 78.
The oversized relation of the opening 70 in the plate 66 to the
bushing provides for lateral adjustability of the plate 66 and thus
the bottom of the post 58 to accommodate possible misalignment
between the floor and ceiling systems 18 and 19. A vertically
upstanding hollow insert 73 shaped complementarily to the inside of
the post 58 bottoms on the bushing 69 and the nut 71 and is
adjustably secured in place by means of a pair of clips 74,74 each
of which includes a horizontal leg 76 which is slotted as at 77 to
receive one of the studs 67 and 68 projecting from the plate 66,
and which is secured to the plate by means of a wingnut 78, and
which also includes a vertical leg 79 which is secured to the
insert 73 by means of a pair of screws 80 and 81. A layer of
gasketing material 82 is provided between the plate 66 and the top
wall 47 of each of the floor rails 21 and 22.
As illustrated in FIGS. 2 and 5, all of the various components
which comprise the pedestal assembly 23 provide a hollow passage
extending from the base 29 all the way up to and into the
cornerpost 58, thus electrical conductors and the like can be run
from the utility space below the floor system 18 up through the
pedestal assemblies 23 and into the corner posts 58 without being
exposed and without extending through any of the floor panels.
The post 58 are erected, of course, only at the corners of the
floor and ceiling sections 25 and 27 which are to be divided or
enclosed with partitioning walls. Mounted between the post 58 along
the floor line are lower partition wall panel rails as indicated in
FIGS. 2 and 7 at reference numerals 87. The rails 87 are similar to
the posts 58 and both may be extruded from the same die. The rails
87 also include threaded screw grooves on each of four sides 88
thereof extending the full length of the rails 87, as indicated at
reference numerals 78, the same reference numerals which indicate
similar screw grooves in the cornerposts 58.
The bottom wall 89 of each of the rails 87 is cut short of the
adjacent post 58 as at 85 to accommodate the threaded studs 67 and
68 projecting upwardly from the post mounting plate 66 and nuts 75
threaded thereon. The rails 87 are of the same widths as and
overlie the floor rails 20 and as shown in FIG. 2, a layer of tile
or the like material 60 which is placed over all of the floor
panels 54 is also placed between the ribs 51 of the floor rails 20.
As indicated at 90 a layer of compressible material such as rubber
or other gasketing material is secured to the bottom wall 89 of the
rails 87 to provide a lighttight seal thereacross.
The ends of the lower partition wall panel rails 87 are secured to
the posts 58 by means of mounting brackets indicated in FIGS. 2, 5,
12 and 13 at reference numerals 92. The brackets 92 each comprise a
faceplate 93 which is deposed between the end of a rail 87 and the
insert 73 and is secured thereto by means of a pair of screws 94
(FIG. 32) which extend through openings 96 formed in the faceplate
93 and which are threaded into the insert 73. Protuberances 97
project from the back face of the plate 93 and into the end of the
rail 87 to rigidify the plate 93 and to prevent axial twisting of
the rail.
In order to provide [additional] vertical support for the two edges
of each of the floor panels 54 which do not confront and which are
not supported by the floor rails 21 and 22 a substringer as
indicated at reference numeral 98 in FIG. 10 is mounted between
each of the sets of floor rails 21 and 22. The cross brace 98
comprises a pair of arms 99 and 100 which intersect at right angles
. The arms 99 and 100 are hollow and have flat parallel top and
bottom walls 101 and 102 and flat parallel side walls 103 and 104.
Telescoped into the ends of the arms 99 and 100 and welded or
otherwise bonded fast thereto are rectangularly shaped tubular
inserts 106 which project between the flanges 53 and 53a of the
floor rails 20 and 21 in the installed position of the substringer
98.
During installation the substringer 98 is placed between pairs of
parallel floor rails 21 and 22 and then turned from the position
thereof shown in dashed lines in FIG. 10 to the position thereof
shown in the full lines. The inserts 106 are dimensioned to provide
a slight interference fit with the flanges 53 and 53a so that when
the substringer 98 is turned to its assembled position it is
maintained in such position by a frictional force between the
inserts 106 and the flanges 53 and 53a. The top walls 101 of the
arms 99 and 100 are flush with a top wall 106 of the flanges
53.
Referring now to FIGS. 15 and 16, the ceiling rails 24 and 26 come
together in abutting engagement at the corners of the ceiling
sections 27 and are mitered at the abutting ends thereof as shown
at 108. The ceiling rails 24 and 26 are identical and may be made
of extruded aluminum or the like and as shown in FIG. 17 each
comprises a pair of spaced vertical sidewalls 109 and 110 on the
bottom wall 111. The upper ends of the sidewalls 109 and 110 are
inturned as at 112 and 113 to provide a groove 114 extending along
the length thereof.
Threaded screw grooves 116 similar to the grooves 78 of the corner
posts 58 are formed in the side and bottom walls 109-111 and a pair
of horizontally extending flanges 117 and 118 project from the
sidewalls 109 and 110 for supporting ceiling panels of the
suspended ceiling system 19, a portion of one such ceiling panel
being indicated at reference numeral 119.
The abutting ends of the ceiling rails 24 and 26 are supported by
means of a ceiling rail connector 120 which is constructed
generally similarly to the floor rail connector 33. Thus the
ceiling rail connector 120 comprises a central hub portion 121 from
which four pairs of fingers extend at right angles to one another
as indicated at 122a-122b to 125a-125b. The fingers extend between
the sidewalls 109 and 110 of the ceiling rails 24 and 26 and
support the rails at the inturned flanges 112 and 113.
The hub 121 is centrally apertured as at 126 to receive a
suspension rod 28 and the connector 120 is mounted for vertical
adjustment on the rod 28 by means of threaded nut and washer
assemblies 127 and 128 situated respectively above and below the
connector 120.
Referring to FIG. 14, and upper end 129 of an exemplary suspension
rod 28 is threaded into a nut 130 disposed within a channel member
131. The channel member 131, in turn, is connected to a second
channel member 132 by means of a threaded stud 133 which extends up
through a chamfered counterbore 134 formed in a top wall 136 of the
channel member 131. The stud 133 is threaded into a nut 137 which
is disposed within the second channel member 132.
Both of the channel members 131 and 132 are similar in construction
and comprise a pair of bottom flanges 138 having out-turned cars as
at 139. The nuts 130 and 137 are also similar to one another and
each comprise a pair of grooves 140 which receive the out-turned
ears 139 of the channel members.
A pair of spring members 141 and 142 are disposed respectively
within the channel members 131 and 132 and are fixedly connected to
their respective nuts 130 at bottom ends 143 by means of a weld or
the like connection. An upper end 144 of the springs abuts the top
wall of its respective channel member.
The suspension rod 28 and the nut 130 are movable along the length
of the channel member 131 to align the suspension rod 28 in one
direction. The rod 28 can then be locked in position in this one
direction by threading the rod into the nut 130 until an upper end
146 of the rod abuts the top wall 136 of the channel member
131.
Similarly, the channel member 131 is adjustable in a second
direction which is transverse to the longitudinal axis thereof by
threading the stud 133 outwardly so that an end wall 147 thereof is
moved out of abutting engagement with a top wall 148 of the channel
member 132. After the channel member 131 has been adjusted in this
transverse direction the stud 133 is threaded into abutting
engagement with the top wall 148 of the channel member 132 to lock
the channel member 131 in place.
The springs 141 and 142 bias the nuts 130 and 137 downwardly
whereby the out-turned ears 139 of the channel member 131 and 132
remain seated in the grooves 140, thereby permitting adjustment of
the rod 28 and the stud 133 without the necessity of holding the
nuts 130 and 137 against rotation.
The channel member 132 is embedded within the structural concrete
ceiling 12 and the bottom flanges 138 thereof are flush with a
bottom wall 149 of the concrete floor 12. A pair of wing flanges
150 and 150a are formed on the channel member 132 to provide a firm
anchor and to preclude pulling of the channel member 132 out of the
structural concrete ceiling 12.
The upper ends of the vertical cornerposts 58 are secured to the
ceiling system 19. Referring to FIGS. 26 and 27, a mounting block
151 is telescoped into an upper end 152 of an exemplary cornerpost
58. The outer wall construction 153 of the block 151 is generally
similar to the inside wall construction of the posts 58. The
central portion of block 151 is bored as at 154 and a
cross-connector 156 is depressed within the bore 154.
The block 151 is preferably constructed of a resilient material and
a top wall 157 thereof abuts the bottom walls 111 of the ceiling
rails 24 and 26 to form a lighttight seal. The cross-connector 156
is bonded by suitable means such as cement to the block 151 and
comprises a pair of crossarms 158 and 159 which project upwardly
beyond the top wall 157 of the block 151 to seat in the threaded
screw grooves 116 of the ceiling rails 24 and 26.
In erecting a cornerpost 58 it is necessary that the post be
lowered sufficiently to enable the top of the cross-connector 156
to pass under the bottom wall 111 of the ceiling rails 24 and 26
until the cross-connector is in vertical alignment with the grooves
116 formed in the bottom walls 111.
Referring to FIGS. 2 and 5 a bottom wall 160a of the erected
cornerpost 58 is spaced above the nut 71. A spring 160 is housed in
the lower end of the post 58 and a top end 162 thereof abuts a
fixed plate 161 and a bottom end 163 abuts an upper end 164 of the
insert 73. The erected post 58 is therefore biased upwardly away
from the floor system 18 and toward the ceiling system 19.
In erecting a post 58 the plate 66 is mounted in place, then the
insert 73 is mounted thereon by means of the clips 74 and the lower
end of the post 58 is telescoped over the insert 73. The post 58 is
then urged downwardly against the bias of spring 160 so that the
top of the cross-connector 156 passes beneath the bottom wall 111
of the ceiling rails 24 and 26. After the crossarms 158 and 159 are
vertically aligned with the screw grooves 116 in the bottom wall
111, the post is released to enable the spring 160 to provide an
upward bias to seat the crossarms 158 and 159 in place in their
corresponding screw grooves 116.
Between the cornerposts 58 various enclosure components such as
wall panels may be erected. For example, referring to FIGS. 18 and
19, a pair of cornerposts identified at 58a and 58b are erected
between the lower partition wall panel rails 87 and the ceiling
rails 24 and 26. A wall panel structure 166 is installed between
the posts 58a and 58b and extends from the panel rails 87 to the
ceiling rails 24 and 26.
In the embodiment shown in FIGS. 18 and 19 the enclosure includes a
pair of wall panels 166a and 166b which are mounted in spaced
parallel relation to form a double-wall enclosure panel. In this
embodiment the edge portions of panels 166a and 166b are
constructed of suitable magnetic material and the panels are
secured to posts 58a and 58b as well as to the lower partition wall
panel rail 87 and the ceiling rail 26 by means of a plurality of
magnets indicated at reference numerals 167. Each of the magnets
167 has a pair of flat sidewalls 168 and 169 abutting the walls of
the panels 166a and 166b and is mounted on a rod 170 by means of a
pair of lock washers 171 and 172. A disc-shaped flange 173 is also
formed on the rod 170 and one end 174 of the rod is threaded
complementarily to the threaded screw grooves 78 of the posts 58a
and 58b and the lower rails 87 as well as to the grooves 116 of the
ceiling rails 24 and 26. The number and spacing of the magnets 167
will generally depend upon the size and weight of the wall panels
167.
A layer of resilient material such as rubber is bonded to the edges
of the panels 166 as indicated at reference numeral 176 to provide
a lighttight seal.
Another embodiment of an [enclosure] wall construction is shown in
FIGS. 20-23 wherein a single-wall panel structure indicated at 177
is adapted for installation between a pair of cornerposts 58. In
this embodiment a hook member 178 is mounted on the inner wall of
each of the pair of corner posts 58 near the upper end thereof by
means of a pair of studs 179 threaded into the screw grooves 78 of
the cornerposts 58. A cooperating hook member 180 is mounted on
each of the cornerposts 58 at the lower end thereof.
Projecting from the upper end of each of the opposite sidewalls of
the panel 177 is a shaft 181. Another shaft 182 projects from the
bottom ends of the panel sidewalls.
To install a panel 177 the upper end is moved into position below a
corresponding ceiling rail 24 or 26 as indicated in the broken
lines in FIG. 20 so that the shafts 181 are moved up into a groove
183 formed in the upper hook members 178 to a position shown in
broken line FIG. 22 at reference numeral 184. Then the lower end of
the panel 177 is moved into a vertical position so that the shafts
182 are received in slots 186 formed in the lower hook members 180.
The panel 177 is then released so that the shafts 182 move to a
lower portion 187 of the grooves 186 and are locked therein and the
upper shafts 181 move down a slight distance in the slots 183 of
the upper hook members 178 where they are locked therein.
A layer of compressible material 188 may be bonded to an upper wall
189 of the panel 177 to provide a light seal while accommodating
the necessary movement of the shafts 181 in the slots 183 necessary
for the installation of the panels 177.
Other embodiments of single-wall panels constructed in accordance
with the principles of this invention are disclosed in FIGS. 24 and
25. In FIG. 24 a rectangular sleeve 190 is telescoped over side
sidewalls 191 and 192 of a wall panel 193. A strip 194 of
compressible material such as rubber is disposed between end wall
196 of the panel 193 and end wall 197 of the sleeve 190 to bias the
sleeve 190 away from the panel and into abutting engagement with
the cornerpost 48. A protuberance 198 is formed on the wall 197 to
project into the threaded screw groove 78 of the cornerpost 58 as
well as into the screw grooves 78 of the lower partition wall panel
rails 87 and the ceiling rails 24 and 26.
The embodiment disclosed in FIG. 25 comprises a wall panel 199
having a plurality of spring-loaded bullet catches 201 extending
from a sidewall 204 into the threaded screw groove 78 of the
cornerpost 58. A spring 201a is mounted in a housing 200 behind
each of the bullet catches to bias the catches outwardly, and a
pair of strips 202 and 203 made of compressible material are bonded
to the wall 204 of the panel to provide lighttight seals along the
edges of the panel 199.
It will be appreciated that the partition wall panels may be
constructed of opaque material or may include glass panes or other
transparent or translucent material. Furthermore, doors may be hung
on the corner posts to provide closures for various modules, as the
floor plan of the area may dictate.
Another embodiment of a partition wall arrangement is shown if
FIGS. 28 and 29 wherein the partition wall comprises a pair of wall
members 206a and 206b mounted between an exemplary lower partition
wall rail 87 and a ceiling rail 26. In this embodiment the panels
206a and 206b may preferably be constructed of opaque material such
as wood, metal or the like.
Mounting brackets 207 are securely fastened to the confronting
walls of the rails 26 and 87 by means of threaded screws 208. Each
of the mounting brackets 207 comprises a flat baseplate 209 which
abuts the confronting wall of its corresponding rail and a pair of
vertical legs 210 which extend from the baseplate 209. At each of
the two ends of the baseplate 209 is formed a bead 211 which
extends in the same vertical direction as the legs 210.
Mounted on an inner wall 212 of each of the panels 206a and 206b is
a mounting clip 213 having a recess 214 formed therein for
receiving a corresponding bead 211. A gasketing member 216 is
mounted on the upper and lower edges of each of the panels and
extends the entire length thereof to provide a lighttight seal
between the panels and the rails.
Mounted on each of the legs 210 of the upper mounting bracket 207
is a magnetic member 217 secured to the leg by means of a fastening
device 218. The magnetic members 217 may extend the entire length
of the panel or may comprise a plurality of individual magnets
spaced along the upper edge of each of the panels. Similarly the
mounting bracket 207 may extend along the entire lengths of rails
26 and 87 or, in the alternative, may comprise a plurality of
individual brackets situated at various spaced locations along the
rails.
In mounting the panels 206a and 206b the bottom edges thereof are
first moved into place as shown in the dashed lines in FIG. 26 such
that the bead 211 of the lower mounting bracket 207 is received in
the recess 214 of its corresponding mounting clip 213. Then the
panel is raised to a vertical position as shown in full lines. If
the panels 206a and 206b are formed of metal the upper edges
thereof are held in place by means of the magnets 217. If the
panels are formed of wood or the like nonmagnetic material then, of
course, magnetic material must be embedded in or otherwise mounted
on the panels at the properly spaced locations.
After the panels 206a and 206b have been raised into assembled
position it is apparent that the lower edges thereof cannot be
moved laterally because of the locking engagement of the beads 214
and the recesses 211. The upper edges of the panels 206a and 206b
are restrained against lateral movement by the forces acting
thereon due to the magnetic members 217.
Where the outer surfaces of the panels are flat erection tools
including suction cups may be used for placing the panels in place
as well as for removing the panels upon dismantling of the
partition wall. Similar apparatus including suction cups may be
conveniently utilized in erecting and dismantling the other
embodiments of the partition wall arrangements.
The embodiment disclosed in FIGS. 30 and 31 comprises a pair of
glass panels 217a and 217b. A thin layer of compressible material
218 surrounds the edges of the glass panels and is disposed between
the glass and a groove 219 formed in a mounting flange 220.
Each of the flanges is laterally recessed as at 221 and secured by
means of adhesive or the like; within each of the recesses 221 is a
magnetic member 222.
Mounted on the confronting walls of the rails 26 and 87 are
mounting brackets 223 secured thereto by means of fastening devices
224. A metal rod 226 is secured in overlying relation on each of
the brackets 223 for abutting engagement with the magnetic members
222 in the assembled position of the panels 217a and 217b.
Referring to FIG. 31, in the recesses 221 of the lower mounting
flanges 220 are flanges 227 each of which comprises a vertical leg
228 having a bead 229 formed at the distal end thereof. Each of the
beads 229 is disposed between a pair of short vertical legs 230 and
231 to prevent lateral movement thereof. Sealing members 232 are
provided between the panels 217a and 217b and the rails 26 and 87
to provide a lighttight seal therebetween.
The panels 217a and 217b are assembled in the same manner as panels
206a and 206b of FIGS. 28 and 29, that is, by first placing the
bead 29 of each of the flanges 28 between its respective vertical
legs 230 and 231 while its corresponding panel is at an angle with
respect to the vertical, and then raising the panel to a vertical
position at which the magnetic members 222 will maintain the panel
securely in place.
The previously mentioned panel mounting apparatus comprising
suction cups may also be advantageously utilized in erecting and
dismantling the glass panels 217a and 217b of FIGS. 30 and 31.
FIGS. 32 and 33 serve to provide an overall composite view of many
of the components of the present architectural system of interior
modular construction. The figures illustrate components used in
more than one arrangement and include such additional features as
electrical outlet plates 233 which may be mounted over an aperture
234 formed in a corner post 58, electrical conductors 236 extending
through the pedestal assembly 23 and up into the corner post 58 to
terminate at a receptacle box 237, etc. When in assembled
condition, the corner posts 58 may be prevented from moving
downwardly under loads which may be imposed thereon by means of a
cam arrangement 236 mounted on the insert 73 for abutting the
bottom wall of the cornerpost 58.
It is apparent from the foregoing that the architectural system of
modular construction disclosed herein provides for maximum
flexibility of the floor plan while requiring minimum time and
effort in rearrangement. Since the floor system, the ceiling system
and the partition wall system are all separate but interdependent,
and since the corner posts are separate from the partition wall
panels and the partition wall panels overlie the partition wall
rails and the ceiling rails rather than the floor and ceiling
panels, the corner posts and partition wall panels can be erected
and removed without any modification of the floor and ceiling
systems. Other features such as the threaded screw grooves in the
rails and cornerposts, the connectors for the floor and ceiling
rails, the pedestal assemblies, etc., also add to the many
advantages of this improved and complete system of modular
construction.
Although minor modifications might be suggested by those versed in
the art, it should be understood that we wish to embody within the
scope of the patent warranted hereon all such modifications as
reasonably come within the scope of our contribution to the
art.
