Description
The present invention relates to a two-sectional displaceable inner
partition the sections of which are connected to supports.
Two-sectional lightweight structural walls are known. With these
known walls, the two sections or forms have their edges connected
to each other by strong bars or ledges. This has the drawback that
such structure greatly favors the transmission of sound.
A two-sectional sound-absorbing wall has become known according to
which the two sections are held in spaced relationship to each
other by a frame. This frame also serves for connection between the
ceiling and the floor. The sections are tightly pressed into the
frame whereby between the sections and the frame a good sound
transfer is made possible. Furthermore, a good fit is required
between the frame and the sections which fit can be obtained only
at relatively high costs. The assembly and disassembly of such
walls is relatively complicated.
It is an object of the present invention to provide a two-sectional
inner partition which will have only relatively few parts and which
can be assembled and disassembled in a particularly short time.
It is a further object of this invention to provide an inner
partition as set forth above which has a good sound and, if
desired, also heat-insulating effect and has considerable strength
while using only nonburnable parts or elements.
These and other objects and advantages of the invention will appear
more clearly from the following specification in connection with
the accompanying drawing diagrammatically illustrating a section
through a two-sectional partition according to the present
invention.
The two-sectional displaceable inner partition according to the
present invention, the sections of which are connected to supports
arranged in spaced relationship to each other, is characterized
primarily in that to the inner sides of said sections in the
vicinity of the end portions thereof spring elements are connected
which easily detachably engage longitudinal profiles of supports.
The sheathinglike wall elements may be connected, with the inner
partition according to the invention, by simply pressing the spring
elements against the profiled portions of the supports whereby the
spring elements snap into or lock with the said profiled portions.
The dimensions and the spring properties of the spring elements may
be so selected that the sheathinglike wall elements can without
great physical effort be mounted by the construction workers by
exerting a pressure along their surfaces. Consequently, the wall
elements may with the inner partition according to the invention be
assembled and disassembled in a minimum of time so that a fast
putting up and relocation of the entire wall is possible.
According to a particularly advantageous embodiment of the present
invention, the springs consist of sheet metal strips, especially
steel sheet metal strips which are cranked several times or are
bent to form tongues which protrude from the sheathing. Such
springs, in addition to having excellent spring characteristics,
have a long life and are resistant against the rough handling on
the building lots. Moreover, such spring elements which preferably
have their surfaces protected, are relatively easily and
inexpensively to produce by cold rolling. If steel sheet metal
strips are employed, it is suggested to use spring steel for such
sheet metal strips inasmuch as the spring steel in addition to
having good spring characteristics also is corrosion resistant.
According to a further feature of the invention, the supports are
designed as hollow profiled beams which in the longitudinal
direction of the wall on diametrically oppositely located sides are
provided with two longitudinal profiles each which are arranged in
spaced relationship to each other and form ribs. It is onto these
longitudinal profiles that complementary groovelike or beadlike
parts of the spring elements may resiliently snap. Such hollow
profiled beams which are of a polygonal cross section or have their
outsides provided with protruding profiles have excellent strength
properties and a low weight and permit a fast but safe mounting of
the wall sheathing. Since in addition to the profiles of the hollow
profiled beams or the spring elements fixedly connected to the
walls no loose parts, such as screws, clamps, cotter pins, wedges,
bolts or rivets, are required for connecting the wall elements, the
individual parts cannot get lost on the building lot and do not
have to be kept in stock.
The protrusions of the supports and the notches or the like of the
spring elements may be of triangular cross section. Such notches,
beads, or the like can with a minimum of effort safely be brought
into locking engagement with the profiles of the supports and can
at any time be disconnected therefrom without the employment of
special tools.
According to a further feature of the invention the gap between two
adjacent outer sections is within the area of said supports covered
by a cover strip on both longitudinal edges of the inner side which
cover strip may have a likewise metallic spring element, for
instance of steel sheet metal strips, which may be resiliently
interlocked with the spring elements of the sections.
In this connection it is particularly advantageous that the spring
elements of the cover strips by means of tonguelike protrusions act
upon the spring elements of the sections on that side which faces
away from the supports and press against the supports. When
disassembling the wall, the cover strip is withdrawn by a force
directed away from the wall and can again be used as can the
sections.
It is particularly advantageous to make the wall elements in the
form of plasterboard or asbestos cement plates. Experience has
proved that an inner partition according to the invention equipped
in this way also possesses excellent heat-insulating properties.
Tests have also proved a considerable fire resistance in conformity
with the fire standards. They also permit any type of surface
covering.
Although as a rule it is advantageous to employ steel sheet metal
strips for the spring elements of the sections or cover strips, it
may be advantageous in some instances to produce such spring
elements of rubber and/or synthetic material with corresponding
profiles which are adapted resiliently to lock into profiles of the
supports. As synthetic material in this connection there may be
used polyamides or polyurethanes with a correspondingly high Shore
hardness, high aging resistance, good heat resistance and a high
spring constant. Such spring elements may be connected to the wall
elements by suitable adhesives, for instance, adhesives on the
basis of a synthetic material. In addition to good sound-absorbing
properties, such materials also have the necessary mechanical
strength.
Referring now to the drawing in detail, the wall sheaths or wall
sections are designated with the reference numerals 1a, 1b and 2a,
2b. These wall sections are preferably made in the form of gypsum
board plates. The sheaths 1a, 1b and 2a, 2b are arranged in spaced
relationship to each other and transverse to the longitudinal
direction x-y of the wall while defining a chamber 3 therebetween
which is filled with insulating material connected to the inner
sides of the sheaths 1a, 1b and 2a, 2b. The insulating material
consists with the particular embodiment shown in the drawing of
mineral wool which in the manner of a fleece or mat is connected to
the sheaths by cementing. The gap between the sheaths 1a, 2a and
1b, 2b is covered by cover strips 5, 6 which likewise may be formed
as gypsum board plates and which may have the same strength and
surface as the sheaths. The arrangement furthermore comprises a
hollow profiled beam 7 which forms a support of a polygonal cross
section. The support 7 has diametrically oppositely located
sides--seen in the longitudinal direction x-y of the wall--provided
with ribs of triangular shape 7a, 7b, 7c and 7d.
Fixedly connected to the sheaths 1a, 1b; 2a, 2b are respectively
spring elements 8, 9; 10, 11. This connection may be effected by
means of staples 12 applied by stapling guns. The spring elements
8-11 consist of cranked steel sheet metal strips bent a plurality
of times which spring like tongues into the space 3 between the
sheaths 1 and 2 and the cover strips 5 and 6. In the vicinity of
their free edges, the spring elements 8-11 have groovelike or
beadlike parts 8a, 9a, 10a, 11a which are designed in conformity
with the protrusions 7a-7d. The spring elements 8-11 are so
designed and arranged that their groovelike or beadlike parts 8a,
9a, 10a, 11a are adapted detachably to snap onto the ribs 7a-7d
when the wall sections 1a, 1b; 2a, 2b are pressed in a direction
toward the support 7, i.e. toward the interior of the wall.
In addition thereto there are further provided spring elements 13,
14; 15, 16 which are fixedly connected to the cover strips 5, 6 in
the same manner as the spring elements 8-11 which means likewise by
means of staples 17 shot in by a stapling gun. The spring elements
13-16 likewise consist of steel sheet metal strips which are bent
or cranked a plurality of times and have a tongue-shaped extension
by means of which they extend or spring into the space 3 between
the sections and the cover strips. In the vicinity of their edge
portions, the said spring elements 13-16 have an angular extension
13a, 14a; 15a, 16a made by bending. The spring elements 13-16 when
in assembled condition spring by means of said angular extensions
13a-16a behind the end sections of the respective associated spring
elements 8-11 of the sections 1a, 1b; 2a, 2b. Such a design and
arrangement of the angular extensions 13a-16a are provided so that
in response to the cover strips 6, 7 being pressed on by a force
directed toward the interior of the walls, they will snap behind
the end portions of the spring elements 8-11.
The arrangement further comprises a sound insulating intermediate
layer 17, 18 which may be of rubber or felt.
As will be seen from the above, a particular advantage of the inner
partition according to the invention is seen in the fact that the
supports and the sections contact each other only through the
intervention of the spring elements whereby a particularly
beneficial sound insulation is obtained. This applies in particular
when the spring elements and the profiled members contact each
other only over relatively narrow strip-shaped surface portions.
Therefore, walls according to the present invention are
particularly suitable for business establishments and machine
shops.
