Description

A STRUCTURE SUPPORT ARRANGEMENT

Field of the Invention [1] The present invention relates to a support arrangement for supporting structures. In particular, although not exclusive, this invention relates to a support arrangement for supporting structures such as hoardings and panels.

Background of the Invention [2] Structures such as hoardings, panels often time need to be erected to form a “’’wall” or “fence” at a construction site or renovation site to fence off areas in which construction or renovation is being carried out. The structure is typically made of wood, wooden composites, or plastics and is typically screwed to a support post. However such an arrangement is not always able to provide sufficient stability to the structure especially during windy conditions or when the structure is pushed by people accidentally. Moreover, if the structures are temporary installations, it is generally not possible to fix the support posts without making any indentations on the ground.

[3] It should be noted that although this present invention is described with reference to supporting hoardings or panels used at a construction or renovation site, the present invention can also be used to support structures such as billboards, advertisement boards, or screens, etc., without departing from the scope of the present invention.

[4] It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other countries.

Description of Embodiments [38] It should be noted in the following description that iike or the same reference numerals in different embodiments denote the same or similar features.

[39] Fig. 1 illustrates a plurality of structure support arrangements 1210, 1220 1230, 1240, 1250, and 1260 stacked along a support post 110 in accordance with a preferred embodiment 100 of the present invention. At a construction site or shop renovation site, multiple stacks of the structure support arrangements are placed along the boundary of the site. One or more hoardings or panels are fixed to the support posts 110. This way, a wall or a fence is formed along the boundary of the site to for example prevent pedestrians from entering into this site.

[40] Fig. 2, illustrates a top perspective view of a structure support arrangement 1220 of the plurality of structure support arrangements 1210 to 1260, in accordance with a preferred embodiment of the present invention. As shown in Fig. 2, the structure support arrangement 1220 comprises a body member 210. In one embodiment of the invention, the body member 210 is made of plastic. Further, in one embodiment, body member 210 is made using a technique selected from a group of technologies including injection moulding, rotary moulding and blow moulding.

[41] Further, the structure support arrangement 1220 includes a nesting formation 220 defined on the body member 210. The nesting formation 220 is configured to prevent lateral movement of the structure support arrangement 1220 in at least one transverse direction when the structure support arrangement 1220 is nested with a further structure support arrangement, particularly, an adjacent similar structure support arrangement 1210 or 1230. The transverse direction is a direction defined by x and y directions (as indicated by the x and y arrows in Fig. 3) and is perpendicular to the longitudinal direction of the support post 110 in operation. For example, a transverse direction that is between x and y directions can be defined by a linear combination of x and y directions. Fig. 3 illustrates the nesting formation 220 in accordance with a preferred embodiment of the present invention. As shown in Fig. 3, the nesting formation 220 comprises an l-shaped projection 2210 and an l-shaped cavity 2220. The l-shaped projection 2210 has one or more projection heads 2212 and a projection neck 2214. Fig. 4 illustrates a bottom perspective view of the structure support arrangement 1220 in accordance with a preferred embodiment 400 of the present invention. As shown in Fig. 4, the l-shaped cavity 2220 has one or more cavity heads 2222 and a cavity neck 2224.

[42] If the structure support arrangement 1220 is nested with the adjacent similar structure support arrangement 1210, the two projection heads 2212 of the structure support arrangement 1220 mate with the two cavity heads of the adjacent similar structure support arrangement 1210. Further, the projection neck 2214 of the structure support arrangement 1220 mates with the cavity neck of the adjacent similar structure support arrangement 1210. The adjacent similar structure support arrangement 1210 is installed on the top of the structure support arrangement 1220. As a result, the lateral movement of the structure support arrangements 1210 and 1220 relative to each other in at least one transverse direction can be prevented. On the other hand, as shown in Fig. 1, the one or more cavity heads 2222 and cavity neck 2224 of the structure support arrangement 1220 mate with the corresponding one or more projection heads and projection neck of the structure support arrangement 1230, which is installed under the structure support arrangement 1220. As a result, the lateral movement of the structure support arrangements 1220 and 1230 relative to each other in at least one transverse direction can be prevented.

[43] Returning now to Fig. 2, the structure support arrangement 1220 further comprises a post receiving formation 230 defined on the body member 210. The post receiving formation 230 is configured for receiving the support post 110. In one embodiment, the post receiving formation 230 is any one or more selected from an aperture and a recess. The post receiving formation 230 includes an opening formed on a side (particularly, the support side 510, as shown in Fig. 5) of the structure support arrangement 1220. Further, in one embodiment, a shape of the post receiving formation 230 conforms to a cross-sectional shape of the support post 110 in order for the support post 110 to fit into the post receiving formation 230. In another embodiment, the shape of the post receiving formation is rectangular regardless of the cross-sectional shape of the support post 110.

[44] In one embodiment, the structure support arrangement 1220 comprises one or more plates (i.e., lip plates) 240 secured to the body member 210, in proximity of the post receiving formation 230. Further, the one or more lip plates 240 are adapted to prevent lateral movement of the support post 110 in at least one transverse direction when the support post 110 is received in the post receiving formation 230. In one embodiment, one lip plate is secured to the body member 210 to entirely or partially cover the opening of the post receiving formation 230 so as to prevent the support post 110 from laterally sliding out of the post receiving formation 230 in at least one transverse direction. In one embodiment in which two lip plates are used, a gap between the two lip plates 240, when secured to the body member 210, is smaller than the opening of the post receiving formation 230, as shown in Fig. 2. Thus when the support post 110 is received in the post receiving formation 230, the one or more lip plates prevent the support post 110 from laterally sliding out of the post receiving formation 230 in at least one transverse direction. In one embodiment of the invention, the one or more lip plates 240 are removably secured to the body member 210, such as by means of one or more fasteners. Further, the one or more lip plates 240 are provided with holes adapted to receive the one or more fasteners in order to secure the one or more lip plates 240 to the body member 210. Accordingly, the body member 210 has threaded holes corresponding with the holes of the one or more lip plates 240. In another embodiment, the one or more lip plates 240 are at least partially embedded in the body member 210 when secured to the body member 210.

[45] In another embodiment, the one lip plate 240 is a pivotable latch adapted to pivot between an open position and a closed position. In the open position, the lip plate 240 enables the support post 110 to move in and out of the post receiving formation 230. In the closed position, the one lip plate 240 prevents the support post 110 from laterally moving out of the post receiving formation 230 in at least one transverse direction. Accordingly, the body member 210 has an embedded pin about which the one lip plate 240 is adapted to pivot. In yet another embodiment, the one lip plate 240 is a slidable latch adapted to slide between the open position and the closed position. Accordingly, the body member 210 has a sliding cavity along which the one iip plate 240 is adapted to slide.

[46] In one embodiment, the structure support arrangement 1220 further comprises one or more dovetail formations 250 defined on the body member 210. Further, the one or more dovetail formations 250 are configured for sliding engagement with one or more dovetail formations on the adjacent similar structure support arrangement 1210 in operation. In one embodiment, the one or more dovetail formations 250 comprise respective one or more dovetail projections 2510 (shown in Fig. 4) and respective one or more dovetail cavities 2520 (shown in Fig. 2). In sliding engagement, the one or more dovetail projections of the adjacent similar structure support arrangement 1210 mate with the one or more dovetail cavities 2520 of the structure support arrangement 1220. The one or more dovetail formations 250 provide additional restriction to the structure support arrangement 1220 against lateral movements in at least one transverse direction.

[47] In one embodiment, the structure support arrangement 1220 further comprises one or more pole receiving apertures 260 defined on the body member 210. In one embodiment, the one or more pole receiving apertures 260 are configured to receive poles. The pole can be part of a structure such as a web with poies at the edges of the web. The pole at one edge of the web is received into the pole receiving aperture 260 of the structure support arrangement 1220, and the pole at another edge of the web is received into the pole receiving aperture of another structure support arrangement. When the web is erected, the two structure support arrangements servers as the bases of the web and keep the web upright [48] In one embodiment, the structure support arrangement 1220 further comprises one or more handle formations 270 defined on the body member 210. Further, the one or more handle formations 270 are configured to facilitate stacking of the structure support arrangement 1220 with the adjacent similar structure support arrangement 1210 or 1230 in operation. Fig. 5 illustrates the structure support arrangement 1220 in accordance with another preferred embodiment 500 of the present invention. As shown in Fig. 5, the structure support arrangement 1220 defines at least one support side 510 and at least one non-support side 520. Further, the structure is supported along the at least one support side 510 in operation. Also, the post receiving formation 230 is located adjacent to the at least one support side 510.

[49] Also, the one or more pole receiving apertures 260 are located towards an edge 540 of the structure support arrangement 1210. In one embodiment, the edge 540 is located at the at least one non-support side 520. Also, in one embodiment, the body member 210 is a hollow member. The hollow member 210 is filled with a coagulable material, such as cement. The coagulable materia! provides a sufficient weight to the structure support arrangement. This provides the structure support arrangement with further stability. A filling aperture 530 is provided at the hollow member 210 at the at least one non-support side 520. The coagulable material is filled into the body member 210 through the filling aperture 530.

[50] As shown in Fig. 1, multiple structure support arrangements 1210 to 1260 are stacked to form a stack of structure support arrangements 1210 to 1260. Multiple stacks of structure support arrangements are placed along the boundary of a site, for example, a construction site or a shop renovation site. The structures, for example, hoardings or panels, are fixed to the support posts 110. Thus, a wall or fence along the boundary of the site is formed to for example prevent pedestrians from entering into this site.

[51] However, due to external forces caused by for example storms, the multiple stacks of structure support arrangements may be displaced. That is, the multiple stacks of structure support arrangements are no longer positioned along the boundary of the site, and the structures fixed to the support posts 110 appear to be like a “snake” when viewed from top. In an extreme case, this may cause the structures to fall off the support posts 110 and damage pedestrians nearby or workers working at the site.

[52] Fig. 6 illustrates a structure support arrangement 1220 in accordance with yet another preferred embodiment 600 of the present invention. As shown in Fig. 6, the structure support arrangement 1220 further comprises a recess 610 defined on the body member 210. The recess 610 is provided along an entire width of the body member 210 with open ends 6110 and 6120 at two sides 620 and 630 of the structure support arrangement 1220, respectively. The recess 610 is configured to receive a horizontal bar 730 that extends to a further structure support arrangement, particularly, into the corresponding recess of a further structure support arrangement (shown in Fig. 7).

[53] Fig. 7 illustrates a plurality of structure support arrangement stacks 7110, 7120 and 7130. The stacks 7110 to 7130 are placed along a boundary of a site. A horizontal bar 730 is placed in the recesses 610 of the top structure support arrangement of each stack 7110 to 7130. The horizontal bar 730 connects the plurality of structure support arrangement stacks 7110, 7120 and 7130, and keep the plurality of structure support arrangement stacks 7110, 7120 and 7130 along the boundary of the site. The structures are fixed to support posts 7210, 7220 and 7230.

[54] If an external force is applied to the structures, the horizontal bar 730 in the recesses 610 of the piurality of structure support arrangement stacks 7110, 7120 and 7130 effectively prevents the displacement of the plurality of structure support arrangement stacks 7110, 7120 and 7130, which dramatically reduces the possibility of the falling of the structures from the support posts 7210, 7220 and 7230. This improves the safety at the site.

[55] The structure support arrangement 1210 to 1260 as described above offers a number of advantages. First, they are easy to manufacture and ship. The design of the body member provides sufficient prevention against displacement in transverse directions. The structure support arrangement allows easy support to structures without making any temporary or permanent indentations on the ground. Further, the structure support arrangement can be easily reused any number of times between different sites. Also, the recess for receiving the horizontal bar prevents the snaking of the structures.
