Description
- This invention relates to builders' equipment. More particularly, although not exclusively it discloses an improved bracket for building scaffolding.
- Examples of a top-plate-hung bracket and stud bracket as currently used for building scaffolding are shown respectively in
FIGS. 1 and 1 A. With the bracket ofFIG. 1 the upper end of thevertical leg 1 is adapted to hang over thetop plate 2 of astud wall frame 2A and thelower end 3 bears against aspreader 4 which is secured across the outer faces of at least three studs including the one shown. Aplank support member 5 extends horizontally out from the vertical leg and is braced by adiagonal strut 6. In use two or more such brackets are fitted along the frame of a building structure and planks are placed across them to produce a working platform in accordance with the relevant building codes including Australian Standard AS6001-1999. This bracket can be time consuming and difficult to set up as access over the top plate for both installation and removal is necessary. There are limitations on the vertical positioning of the bracket due to the use of the top plate for support. There is a substantial bending moment placed on the frame resulting from loading concentrations on the top plate and bottom spreader which causes the stud to twist and deform laterally. The bracket also puts a heavy reliance on welded joints at the upper end of the leg which must carry substantially the whole weight of the assembly. With the stud bracket ofFIG. 1A thehorizontal plank support 6A andstrut 6B are attached directly to upper andlower spreaders stud 6E and the adjacent studs. In this case the majority of the load is carried by the lower spreader which is only nailed or pinned in place. Also, the oppositely directed point loads from the spreaders creates a pinching action onstud 6E which deforms it. - It is therefore an object of this invention to ameliorate the aforementioned disadvantages and accordingly a bracket is disclosed for use in building construction, said bracket having a support leg with at least one attachment point for fixing onto a building frame component, said attachment point including a gripping member mounted on a pivotal linkage extending from said support leg whereby in use of the bracket to carry a working load said leg and gripping member can be located against opposite faces of the building component so that the working load generates a clamping force on said component between the gripping member and support leg which resists movement of said bracket.
- Preferably but not essentially said gripping member comprises a friction member.
- It is further preferred that the friction member includes a plate with a fluted or grooved surface for enhanced grip on the building component.
- It is further preferred that said linkage means comprise a U-shaped strap.
- The currently preferred embodiments of this invention will now be described with reference to the attached drawings in which:—
-
FIG. 2 is a schematic side elevation view of a scaffold bracket according to said invention, -
FIG. 2A is an end elevation view of the bracket ofFIG. 2 along the direction of arrow A, -
FIG. 3 is a schematic side elevation view of the bracket ofFIG. 2 with a stanchion socket fitted, -
FIGS. 4 and 4 A show a schematic side elevation view and perspective view of a second embodiment of the invention, -
FIG. 5 shows a schematic side elevation view of a third embodiment of the invention, -
FIGS. 6 and 6 A show a schematic side elevation view and perspective view of a fourth embodiment of the invention, and -
FIGS. 7 and 7 A show a schematic side elevation view and perspective view of a fifth embodiment of the invention. - Referring first to
FIGS. 2 and 2 A there is shown a scaffold bracket of welded steel construction. In accordance with known design it comprises avertical support leg 7, horizontal platform support orplank support 8 anddiagonal brace 9. Anend plate 10 is also provided at the outer end of the plank support which is of sufficient height to contain overlapping platform planks (not shown). The cross-sectional dimensions of the members used to construct this bracket are in accordance with the relevant industry standards and would be known to a person skilled in the art. The size of the bracket can be varied depending upon whether a single or multi-plank platform is used. - In accordance with this invention the
vertical leg 7 of the bracket is fixed to abuilding frame stud 11 at upper and lower attachment points indicated generally as 12, 13. The upper point comprises aU-shaped strap 14 which is pivotally attached across its open end to theleg 7 by a bolt orpin 15. The opposite closedend 16 of the strap extends around theinner face 11A of the stud as well as afriction plate 17. The strap is also pivotally attached to the friction plate by a second bolt orpin 17A. A clearance space is provided between theend 16 of the strap and theplate 17 to allow for pivoting movement. - The
lower attachment point 13 comprises a pair offlanges 18 which extend out from theleg 7 and closely straddleopposite sides 11B of the stud. In order to comply withindustry standards spreaders Spreader 20 is preferably located in a niche formed between ashoulder 21 extending down from the bottom of theleg 7 and thestud 11. In order to allow for vertical movement of the leg when the bracket is loaded agap 21A of at least 20 mm between thespreader 20 and saidleg 7 is preferred. - When the bracket is installed as shown and carries a load B from a working platform the surface resistance between the
friction plate 17 andstud 11 together with the downward force onleg 7 generates a turning moment orcouple 21 on the strap which clamps thestud 11 at this point and compresses it along a vertical plane between saidplate 17 andleg 7. The magnitude of this clamping force on the stud is determined by the size of the platform load. The inventor has found that this novel clamping arrangement reduces twisting and lateral deformation of the stud as is encountered with prior art brackets. A scaffold bracket according to this invention thus provides a stronger and safer support for working platforms. - Although the
plate 17 may be fluted or grooved to increase grip on the stud as described earlier the depth of these flutes or grooves is preferably chosen to limit excessive penetration or biting into the stud which could reduce strength. Aclout 22 is also preferably driven through the strap and into the stud adjacent the friction plate to hold said plate at the position shown prior to loading. - This version of the bracket may also be fitted with a
stanchion socket 23 as shown inFIG. 3 which contains the planks instead of theend plate 10. The socket is adapted to receive a guard-rail stanchion (not shown) for edge protection. Additional support for the guardrail against transverse loading can be obtained by fitting agusset 23A between thesocket 23 andhorizontal member 8. - With the second to fifth embodiments of the invention shown respectively in FIGS. 4 to 7A the main components that correspond in function to those of
FIGS. 2 and 2 A are identified by the same numbers which however are primed (′), (″), (′″) and (″″) to distinguish them. - With reference to
FIGS. 4 and 4 A the second embodiment of the invention comprises a floor edge rail bracket. There is avertical stanchion 24 with guard-rails 25 which is attached to thesupport leg 7′ by a pair of shorthorizontal bars 26 so that it is positioned up against thefloor joist 26A and close to the edge of anelevated deck area 27. There is a single attachment point near the lower edge of the leg withpivoted strap 14′ andfriction plate 17′ which in use of the bracket are secured close under thetop plate 28 on awall stud 11′. With this embodiment the angle A of thestrap 14′ should be not more than about 20 degrees to the horizontal. - The third embodiment of the bracket shown in
FIG. 5 is a roof rail bracket and post assembly where thestanchion 29 is shown fitted intosocket 23″. Thestrut 9″ in this case is located above thehorizontal member 8″. The lower attachment point also comprises asecond U-shaped strap 31 which is bolted at 32 to thevertical leg 7″ and is held in position against thestud 11″ by a clout 33″. Thisstrap 31 operates in the same way as theflanges 18 of the first embodiment but has the advantage of being readily removable at the completion of brickwork. There is a reinforcinggusset 23″ fitted between thesocket 23″ andstrut 9″. - The fourth embodiment of the bracket shown in
FIGS. 6 and 6 A is another form of roof rail bracket and post assembly. Here thesupport leg 7′″ is adapted for fitting horizontally along the underside of aroof truss 34. There is afriction plate 17′″ at one end of thesupport leg 7′″ with a singlepivotal strap 14′″ which extends around theroof truss member 34 and is orientated to hold the other end of theleg 7′″ hard against the inside of thetop plate 35. Thestanchion 36 with guard-rails 37 fits into asocket assembly 38 welded to theleg 7′″ and is positioned over said top plate (FIG. 6 ). Alternatively the socket and stanchion can be mounted further out on an extension arm 39 (FIG. 6A ). - The fifth embodiment of
FIGS. 7 and 7 A is a roof rail gable bracket. In this case thehorizontal support leg 7″″ is adapted to fit along the top of ablock 40 between adjacent roof trusses 40A and 40B. There is also a secondU-shaped strap 41 andfriction plate 42 located at the opposite end of thesupport leg 7″″. These straps are angled in opposite directions as shown to lock the bracket against transverse movement along the block. Thestanchion 43 with guard-rails 44 fits into asocket assembly 45 welded to the outboard end of thesupport leg 7″″ which extends out onto thegable outrigger 46. - It will thus be appreciated that this invention at least in the form of the embodiments disclosed provides a novel and improved form of scaffold bracket for working platforms and/or edge rail protection. Clearly however the examples described are only the currently preferred forms of the invention and a wide variety of modifications may be made which would be apparent to a person skilled in the art. For example the size and design of the bracket as well as the shape and configuration of the straps and friction member may be changed according to installation requirements. Also, the contacting surface of the friction member could use means other than flutes or grooves such as a layer of rubber or other non-slip material to obtain a frictional grip without departing from the scope of the invention. The invention is further not limited to any specific material for constructing the bracket although a structural steel conforming to the requirements of the relevant industrial standards is preferred for the described embodiments.
