Description
The present invention relates to expansion joint cover assemblies
for buildings and more particularly to an expansion joint cover
assembly for covering adjacent portions of spaced structural
sections which are prone to vary in position relative to each
other.
It is well known that in building structures of monolithic
concrete, concrete blocks, bricks and the like, relatively long
walls, ceilings, and floors, must have expansion joints to prevent
cracks due to expansion and contraction. Also due to earth movement
it is necessary in such building structures to make portions in
sections with expansion joints therebetween to accommodate the
expansion, contraction and movement, even those caused by
earthquake tremor.
Various arrangements of strips over the expansion joints have been
made to make sightly structure even with the sections moved from
the original positions. However, the cover structure and mountings
heretofore used, have been difficult to install or have not been
capable of handling all conditions or were considered unsightly.
Such strips primarily accommodated relative movement of the
building's sections in a single plane and in many instances are
inefficient in providing suitable protection.
The principal objects of the present invention are: to provide an
expansion joint cover assembly particularly designed to cover
expansion joints between spaced building sections, such as floors,
floors and walls, walls, walls and ceilings, and ceilings, which
eliminate the difficulties above mentioned; to provide such an
expansion joint cover assembly adapted to cover an expansion joint
between adjacent structural sections having concrete, concrete
blocks, brick, or metal, or combinations thereof, with portions of
the expansion joint cover structure being adapted to accommodate
relative movement between the adjacent structural sections in any
direction; to provide such an expansion joint cover assembly which
includes an elongated rigid plate member having a width greater
than that of a joint between the structural sections and having
opposite edge portions thereof maintained in firm engagement with
the adjacent structural sections while permitting relative movement
therebetween; to provide such an expansion joint cover assembly
particularly designed to overlie a joint between adjacent
structural sections disposed in a generally common plane and
structural sections disposed in generally perpendicular
relationship with a pivotal connection and a resilient structure
urging the cover plate into contact with the structural sections;
to provide such an expansion joint cover assembly particularly
designed to cover the joint between an existing structural section
and a newly constructed structural section and between adjacent
newly constructed structural sections; to provide such an expansion
joint cover assembly wherein the components thereof are elongated
members particularly adapted to be formed by extrusion processes;
and to provide such an expansion joint cover assembly which is
economical to manufacture, easily installed, convenient to repair
or replace and which can be mounted on exterior or interior
surfaces after the building structure has been completed, which is
decorative when installed, and which permits multiple directional
relative movement of the building sections at the joint
therebetween.
Other objects and advantages of this invention will become apparent
from the following description taken in connection with the
accompanying drawings wherein are set forth by way of illustration
and example, certain embodiments of this invention.

Referring more in detail to the drawings:
The reference numeral 1 generally designates an elongated joint or
space between adjacent portions of a building structure 2 having
structural sections 3 and 4 separated by the expansion joint or
space 1. The building sections 3 and 4, may be floor, wall, or
ceiling sections and may be of monolithic concrete, building
blocks, brick, metal, or any combination thereof, or other suitable
material. In the structure illustrated, the building sections 3 and
4 have outer or exposed faces 5 and 6 respectively, with an
expansion joint cover assembly 7 having portions covering the joint
1, as shown in FIGS. 1 and 2, and engaging the spaced structural
sections 3 and 4. The expansion joint cover assembly 7 is adapted
to permit and accommodate relative movement between the adjacent
structural sections 3 and 4 in any direction.
In the structure illustrated in FIGS. 1 and 2, the expansion joint
cover assembly 7 includes an elongated rigid base member 8 adapted
to be mounted on the outer face 6 of one of the structural
sections, for example, building section 4 adjacent a margin
thereof. The base member 8 is preferably formed of metal or other
suitable material and is an elongated strip.
The base member 8 is illustrated as having a first portion 9
extending generally perpendicular to the outer face 6 and a second
portion 10 extending generally perpendicular to the first portion 9
and having an outer edge 11 terminating adjacent the joint 1. The
base member 8 is preferably positioned in the forms and thereby
secured to the building section 4 along the margin thereof and
adjacent the joint 1 by suitable fastening devices, such as spaced
anchor bolts 12, being in position when the section is formed. In
the illustrated structure, the base member 8 includes an elongated
slot 13 sized to receive a head portion 14 of the anchor bolts
12.
The base member 8 is also adapted to be secured to a respective
building section constructed to have a preformed recess or shoulder
along the marginal edge thereof for receiving same. One of the
first portion 9 and second portion 10 of the base member 8 has a
plurality of apertures 15 spaced longitudinally therealong for
receiving a shank portion of a bolt (not shown) to be threadedly
engaged in suitable bushings (not shown) recessed in holes drilled
in the respective building section wherein the bushings are
anchored in the section in any suitable manner as, for example, the
bolts and bushings forming expansion bolt structures for anchoring
the base member 8 to the respective building sections.
The first portion 9 of the base member 8 has an outwardly
projecting portion 16 which extends from the first portion 9 and
has an upstanding rib 17 complimentary to and designed to
interengage with an edge of an elongated rigid support member 18
overlying the base member 8 and suitably secured thereto. In the
illustrated structure, the first portion 9 of the base member 8 has
an elongated ribbed recess 19 adapted to receive a suitable
threaded fastening device, such as a flat headed screw 20,
extending through the support member 18 and longitudinally spaced
therealong.
The support member 18 is preferably formed of metal and is an
elongated strip and is illustrated as a generally T-shaped member
having a flange portion 21 positioned generally parallel with the
outer face 6 of the section 4 or an exterior surface of finishing
material thereon and a stem portion 22 extending generally
perpendicular to the flange portion 21 and parallel with the first
portion 9 of the base member 8 and preferably having one surface
thereof in engagement therewith. The flange portion 21 is generally
centered relative to the stem portion 22 and has a mounting portion
overlying the ribbed recess 19 with a plurality of longitudinally
spaced countersunk apertures 23 to receive the flat head screws 20.
The flange portion 21 of the support member 18 has a support
portion extending beyond the stem portion 22 and toward the joint 1
between the structural sections 3 and 4.
An elongated rigid plate member 24 preferably of metal or other
suitable material which has a width greater than that of the joint
1 between the structural sections 3 and 4 and is positioned to have
an inner surface 25 thereof overlying the joint 1 and edge portions
thereof engaging the structural sections 3 and 4. In the
illustrated cover assembly, the plate member 24 has opposite edge
portions 26 and 27 overlying and in engagement with members on the
other structural section 3 or finishing material thereon and the
flange portion 21 of the support member 18 respectively.
It is preferred that the base member, support member, and cover
plate be of a structure for forming by extrusion method for economy
of manufacture, therefore, all of the sections of the members are
uniform for the length of the joint except for anchoring
indentations or projections made during assembly.
It is desirable to provide means connecting the plate member 24 and
the support member 18 for holding the plate member 24 in position
overlying the joint 1 between the building sections 3 and 4 and
closing the joint 1 therebetween and for permitting relative
movement between the building sections in any direction and bodily
movement of the plate member 24. A pivotal connection is provided
in the form of an elongated hinge structure connecting a connecting
member to the base member and to the plate member and in the
illustrated structure, an elongated recess 28 is formed in the
inner surface 25 of the plate member 24 and a similar elongated
recess 29 is formed in a joint facing surface 30 of the stem
portion 22 of the support member 18. The recesses 28 and 29 are
preferably identical and are generally cylindrical and formed by
arcuate arms extending from the respective surface and having
facing free ends.
The recesses 28 and 29 are designed to receive enlarged edge
portions 31 and 32 respectively of a connecting member 33 extending
between the plate member 24 and the support member 18 for holding
the plate member 24 in position overlying and closing the joint 1
while permitting bodily movement of the plate member 24 relative to
the base member and relative movement between the structural
sections.
The connecting member 33 is illustrated as having a pair of
connected flanges 34 and 35 positioned in normal relation with the
inner surface 25 of the plate member 24 and the joint facing
surface 30 of the stem portion 22 of the support member 18
respectively. The connecting member 33 may be a plurality of short
sections spaced along the plate member 24 and the support member
18, however, the connecting member 33 is preferably of metal and is
an elongated member as, for example, an aluminum extrusion.
The enlarged edge portions 31 and 32 are positioned at the free
edge of the flanges 34 and 35 respectively and are generally
cylindrical and are slightly smaller than the recesses 28 and 29
and the flanges 34 and 35 have a thickness less than the spacing
between the free ends of the arcuate arms forming the recesses 28
and 29 whereby the recesses 28 and 29 and the edge portions 31 and
32 are sized and shaped to permit relative movement between the
connecting member 33 and the plate member 24 and the support member
18.
Suitable resilient means, such as springs, sponge rubber, or the
like, are provided to hold the plate member 24 in contact with the
structural sections 3 and 4. The resilient means engage the
connecting member 33 and one of plate member 24 and the support
member 18 to urge same apart.
In the illustrated structure, the joint facing surface 30 of the
stem portion 22 has a pocket 36 formed therein which is adapted to
receive a portion of each of a plurality of spaced resilient
members 37 therein. Each resilient member 37 has a mounting portion
and a pair of spaced arms 38 and 39 extending from the mounting
portion with one of the arms, for example, arm 38 engaging the
flange portion 21 of the support member 18 and the other arm 39
engaging one flange, for example, flange 35, of the connecting
member 33 for urging same apart whereby the connecting member 33
holds the edge portions 26 and 27 of the plate member 24 in
engagement with the structural section 3 and the flange portion 21
of the support member 18 respectively. Each resilient member 37 is
preferably a narrow generally U-shaped member formed of spring
steel and longitudinally spaced along the support member 18 and the
connecting member 33.
The expansion joint cover assembly 7 is particularly adapted to be
employed as a threshold between and covering a joint between an
existing floor and a new floor of an extension of the respective
building. An outer surface of the plate member 24 may receive any
desired ornamental treatment, such as plain, serrated, or having a
suitable abrasive material therein.
Installation of the expansion joint cover assembly 7 includes
mounting the base member 8 on one of the structural sections by
being in position during construction of the respective section, as
by being secured in forms when concrete is placed, or by being
secured to a finished section by expansion bolts. The support
member 18 may be secured to the base member 8 prior to the mounting
thereof on the structural section or the support member 18 may be
secured to the base member 8 after same is in place so as to be
substantially a composite base member as if the base member and
support member were formed as one piece. The connecting member 33
is mounted on the plate member 24 and the support member 18 and the
resilient members or springs 37 are mounted in the pocket 36 and
longitudinally spaced therealong and the support member 18 is
suitably deformed or indented, as at 40, on each side of each
spring to maintain the springs in position all preferably before
securing the support member to the base member.
However, it is preferably to assemble the support member 18,
connecting member 33, plate member 24 and the resilient members or
springs 37 in the factory or other suitable location and install
the assembled members on the base member 8 by engaging the edge of
the flange portion 21 of the support member 18 with the upstanding
rib 17 to obtain sufficient leverage to flatten out the cover
assembly which increases the tension on the springs 37 and then
secure the cover assembly to the base member 8 with the screws 20.
The assembly of the components or members of the cover assembly
includes sliding the enlarged edge portion 31 in the recess 28 from
one end of the support member 18. The springs 37 are then snapped
into position individually in the pocket 36 at the locations along
the support member 18. The plate member 24 is positioned at one end
of the connecting member 33 with the enlarged edge portion 31
received in the recess 28 and the edge portion 27 clearing or above
the flange portion 21 and then slid along the connecting member 33
to a position aligned with the support member 18 and connecting
member 33.
It may be desirable to provide a flexible material extending across
the joint between the structural sections to form a gutter having
opposite edge portions suitably supported on the structural
sections 3 and 4, such as shown in FIGS. 1 and 2, for collecting
moisture passing between the structural sections and conveying same
to a suitable point of disposal, such as down-spout or a plumbing
system (not shown).
FIGS. 3 and 4 illustrate a preferred specific embodiment of the new
expansion joint cover assembly to cover an expansion joint 41
between adjacent building sections 42 and 43 which can be either
wall, floor, or ceiling sections. In this embodiment, a base member
8 is secured in position adjacent a margin of each of the building
sections 42 and 43 and in opposed relation. Support members 44 and
45 are secured to the base member 8 on the building sections 42 and
43 respectively, as previously described. A mounting portion 46
extends outwardly from a support portion of a flange portion 48 of
each of the support members 44 and 45.
An outer face of a suitable seal member 49 is generally in the same
plane as an outer face 50 of each of the building sections 42 and
43 or an exterior surface of finishing material thereon, such as
floor, wall, or ceiling tile. The support portion 47 of the flange
portion 48 of the support members 44 and 45 extends inwardly from
the seal member 49 to support opposite edge portions 51 and 52 of a
plate member 53 overlying the joint 41 to thereby permit an outer
surface 54 of the plate member 53 to be generally in the same plane
as the outer face of the seal members 49 and the outer face 50 of
the building sections 42 and 43.
An inner surface 55 of the plate member 53 has a pair of spaced
recesses 56 and 57 each similar to the recess 28 in the inner
surface 25 of the plate member 24. The enlarge edge portions 31 and
32 of a connecting member 33 are received in one of the recesses 56
or 57 and a recess 58 in a joint facing surface of a stem portion
59 of one of the support members 44 and 45 respectively, to thereby
permit relative movement in any direction between the plate member
53 and the support members 44 and 45 to thereby accommodate
relative movement between the building sections 42 and 43.
In the embodiment illustrated in FIGS. 3 and 4, accommodation of
said relative movement between the building sections 42 and 43 is
provided by pivotally supporting the edge portions 51 and 52 of the
plate member 53. The illustrated edge portions 51 and 52 have
rounded depending portions 51' and 52' respectively extending
therefrom and supported on a portion of one of the seal members 49
and on one of the support members 44 and 45 respectively. It is
preferable to provide a suitable recess in an outer surface of at
least one of the support members for pivotally supporting a
respective edge portion of the plate member 53, for example a
recess in the flange portion 48 of the support member 45 to receive
the depending portion 52' of the edge portion 52, whereby one edge
portion is pivotally supported on a portion of a seal member 49 and
the other edge portion is pivotally supported in a recess in one of
the support members.
FIGS. 5 and 6 illustrate an embodiment of the new expansion joint
cover assembly for use in corners to cover an expansion joint 60
between building sections 61 and 62 disposed in generally
perpendicular relation, such as floor and wall sections
respectively, or ceiling and wall sections respectively. That is,
where one of the building sections substantially abutts against the
face of the other section with the joint 60 therebetween. In this
embodiment, a base member 8 and a support member 63, similar to the
support members 44 and 45, as previously described, is secured in
position on one building section, for example building section 62,
and positioned having a flange portion 64 extending generally
parallel with the surface of the one building section 62 and toward
or normal to the adjacent surface of the other building section
61.
A cover member 65 is of generally transversely L-shaped
configuration and is provided with a first generally planar portion
66 which is in engagement with the flange portion 64 of the support
member 63 and a second portion 67 which is generally perpendicular
to the first portion 66 and extends normal to the first portion 66
and hingedly connected to a second support member 68 secured to the
other building section 61.
In the illustrated expansion joint cover assembly, the second
support member 68 has a plurality of apertures spaced therealong to
receive suitable fastening devices in the form of bolts or screws
69 threadedly engaged in suitable bushings 70 in the respective
building section. The bushings 70 being anchored in the section in
any suitable manner as, for example, the bolts and bushings forming
expansion bolt structures for anchoring the second support member
68 to the respective building section.
The hinged connection of the cover member 65 is illustrated as
including a recess 71 in the second support member 68, generally
similar to the recesses 28, 56, and 57, sized to receive an
enlarged edge portion 72 of the second portion 67 of the cover
member 65. The hinged connection permits the first portion 66 to
move relative to the second support member 68, therefore, a
suitable resilient member 73 is mounted in a recess in the second
support member 68 and positioned to be engaged by and deflected by
an edge of the cover member 65 when the cover member 65 is moved
toward the second support member 68 in response to relative
movement of the building sections 61 and 62.
An inner surface 75 of the cover member 65 has a recess 76 similar
to the recess 28 in the inner surface 25 of the plate member 24.
The enlarged edge portions 31 and 32 of a connecting member 33 are
received in the recess 76 and a recess 77 in a joint facing surface
of a stem portion of the support member 63 respectively to thereby
permit relative movement in any direction between the cover member
65 and the support member 63 and 68 to thereby accommodate relative
movement between the building sections 61 and 62.
The expansion joint cover assemblies, illustrated in FIGS. 1 to 6
inclusive, provide member sets for mounting on respective building
sections adjacent a joint therebetween wherein at least one of the
sections has a shoulder or cavity therein opening toward the joint
and a base member 8 and a selected support member is mounted
thereon with a portion of the support member extending toward the
joint to provide support for a covering member in the form of a
plate or L-shaped member held in joint covering and closing
relation by a connecting member and spaced resilient members urging
the cover member into firm engagement with portions of the
expansion joint cover assembly or the building sections.
The width of the respective cover member may be varied to cover the
various widths of expansion joints and a large variety of joint
cover assemblies and arrangements may be provided for accommodating
various building and joint arrangements and conditions with the use
of only a few different parts due to the ability to arrange the
respective parts to accommodate the different arrangements.
It is to be understood that while I have illustrated and described
certain forms of my invention, it is not to be limited to these
specific forms or arrangements of parts herein described and
shown.
