Abstract

A temporary support structure (10) comprises a partition of upright members (11). Attached to the upper and lower ends of the upright member (11) are horizontal members including an upper cross member (12). A horizontal support member (15), typically of steel U-section is connected to a similarly formed deflection head (15). The deflection head (15) is temporarily attached to the partition (10) by way of threaded fasteners or the like (20) extending through the support member (15), the upper cross member (12) and an upper region of each upright member (11). Supported by support member (15) is steel decking (16) which may be corrugated. Above the steel sheeting (16) is concrete (17) of a floor. Once having served the purpose of temporarily supporting the floor (17) during construction, the screws (20) may be removed to allow settlement of the floor toward the upper cross member (12). A gap should always remain between the decking (16) and upper cross member (12).

Description

TEMPORARY FLOOR SUPPORT AND PARTITION Field of the Invention

The following invention relates to a temporary floor support and partition. More particularly, though not exclusively, the invention relates to a steel framed partition which during construction of a building acts as a lightweight temporary floor support.

The floor support partition of the present invention is typically adapted to support a concrete floor upon steel decking. However, the invention may also be applicable for the temporary support of a ceiling or roof or the like.

Disclosure of the Invention

There is disclosed herein a temporary support structure for building construction comprising: a partition having upright members and upper and lower horizontal members defining a right angled parallelogram, a horizontal support member temporarily structurally attached to said partition and spaced above said upper horizontal member and adapted in combination with said partition to temporarily support a vertical load thereabove, and means for detaching said support member from said partition so as to render said partition non load bearing during or after construction.

Preferably, said horizontal support member is an inverted steel U-channel .

Preferably, said inverted U-channel is temporarily attached to said partition by screws extending between respective opposing walls of the U-channel and said partition.

Alternatively, two angle sections can be used in lieu of the said inverted U-channel with the vertical legs against each side of the upper horizontal member of the partition. The horizontal legs of the angles, each side of the upper horizontal member may extend towards or away from each other.

In situations where the temporary vertical load applied to the partitioning is zero, the inverted U-channel may be fixed to the sheeting/slab separate from the manufactured partition. Alternatively, a vertical dowel attached to the sheeting/slab passing through a hole in the upper horizontal member of partition may be used instead of the U-channel or angle sections. Preferably, the upright members and upper and lower horizontal members of the partition are each formed of steel section.

Preferably, the inverted U support member is temporarily attached to steel decking thereabove by way of a threaded fastener, rivet or the like.

Preferably, access is gained to said threaded fastener, rivet or the like from above or from below by a hole formed through said upper horizontal member.

Preferably, each of said upright members is provided with an aperture through which a steel rod or hollow pipe may extend horizontally between adjacent uprights.

Preferably, a support angle is attached to said partition, said support bracket extending essentially horizontally and being attached to the partition by a bracing link either cooperating with said aperture in said upright or with a steel rod extending therethrough.

Such a support bracket would be adapted to support a temporary beam upon which said steel decking is supported.

It should be appreciated that the steel decking receives a concrete floor or the like. By use of the above disclosed support structure, part of the weight of the concrete floor above the steel decking is temporarily supported by the partition until such time as the concrete has set and is permanently supported by permanent supporting walls, columns or the like. At this point, the support member is detached from the partition to allow for any slight settlement of the floor whilst rendering the partition as a non load bearing internal wall for example. Brief Description of the Drawing

A preferred form of the present invention will now be described by way of example with reference to Fig. 1 which is a schematic elevational view of a temporary support structure. Description of the Preferred Embodiment

Referring to Fig. 1, there is schematically depicted a support structure 10. Support structure 10 comprises a partition consisting of upright members 11, one of which is depicted. Each upright is typically formed of steel channel section, typically U-channel.

Typically, items 11, 12, 15 and 16 form of steel having a plate thickness in the range of 0.75 to 1.2 mm. Attached to the upper and lower ends of the upright members 11 are horizontal members, an upper cross member 12 of which is depicted.

Also attached at the upper region of partition 10 is a horizontal support member 15, also formed of steel U section. The support member, typically a deflection head 15 is temporarily attached to the partition 10 by way of threaded fasteners 20 extending through the support member 15, the upper cross member 12 and an upper region of each upright member 11. Screws 20 may be replaced by any other means of temporarily fastening the respective components, for example by way of a rivet. Supported by support member 15 is steel decking 16 which may be corrugated. Typically, Bondek™ sheeting produced by BHP is applicable, although any other suitable alternative sheeting may be adopted. Above the steel sheeting 16 is concrete 17 of a floor.

Support member 15 is secured to the steel sheeting 16 by fastener 14, typically a screw or rivet. Access is gained to screw 14 by access hole 13 in upper cross member 12. By this access hole, a screw driver or the like may be applied to fastener 14. Alternatively, the fastener 14 may be fixed from above the steel sheeting.

Upright member 11 is provided with a circular aperture 18 through which a steel tube or rod may horizontally extend between adjacent uprights. Alternatively, a bracing link 19 may be applied through hole 18 to serve as a means of supporting a support bracket 21 which is typically a horizontally extending length of angle iron. Bracing link 19 is typically formed of steel rod formed into a U-shape. One leg of the U extends into the corner of support angle 21. The bracing link 19 is typically a hook bolt.

Rather than passing the other leg of the bracing link U into hole 18, an alternative structure may be provided to affix the bracing link 19 to a steel rod extending into hole 18. Supported by support angle 21 is an optional block 22 upon which there is provided a temporary wooden beam 23 also serving as a means of supporting the decking 16 upon which concrete 17 is poured.

It should be appreciated that the type of construction to which the present preferred embodiment is applicable, also comprises permanent supporting walls and/or columns which take the weight of the floor 17 in the finished construction. Such walls and/or columns are not shown in the drawing. In use, the partition 10 which comprises uprights 11 and horizontal members 12 (also a lower horizontal member, not shown) is delivered to the construction site with the support member 15 fixed thereto.

Once having served the purpose of temporarily supporting the floor 17 during construction, either solely by transfer of load through support member 15 or additionally by temporary wooden steel or aluminium beams 23, the screws or rivets 20 are removed to allow settlement of the floor toward the upper cross member 12. It should be appreciated that an initial gap of several centimetres might marginally reduce during settlement, however a gap should always remain between the decking 16 and upper cross member 12. That is, once the construction is completed, the partition 10 is essentially non vertically load bearing, serving as an internal wall, having lateral load capacity.

It should be appreciated that modifications and alterations obvious to those skilled in the art are not to be considered as beyond the scope of the present invention. For example, the partition 10, rather than being formed of steel sections may be formed of wood, aluminium or any other suitable material.
