LOCKED BAG NO. 5, HAWTHORN, VICTORIA 3122, AUSTRALIA Complete Specification for the invention entitled: DEMOUNTABLE AND RELOCATABLE INTERLOCKING BUILDING HOARDING PARTITIONS AND TEMPORARY SECURITY FENCING The following statement is a full description of this invention, including the best method of performing it known to us 1.

LL.

2 DEMOUNTABLE AND RELOCATABLE INTERLOCKING BUILDING HOARDING PARTITIONS AND TEMPORARY SECURITY FENCING Field of Invention This invention relates to a portable, demountable and/or relocatable fence, and in particular, to a new system of erecting, dismantling and relocating building hoardings, temporary chainwire security fencing and internal temporary low level wall partitions.

Backaround Art Building hoardings and temporary security fences are ordinarily constructed in a fixed manner at the erection site using timber or steel posts driven or fixed in the ground, rails and plywood panel sheeting all bolted and nailed together. Some applications use bolted scaffold tubing as a framework but this method, whilst reducing material wastage, is labour intensive.

Temporary chainwire fencing is generally constructed of lightweight materials and is largely scrapped after a single use. Heretofore, there has been no successful way known to economically factory fabricate hoardings and temporary fences that can be readily erected and dismantled up to twenty times.

General acceptance in the building industry is for four to six uses of temporary fence materials.

Definition Throughout this specification the term fence includes within its scope a hoarding, partition, wall or other form of baricade.

Summary of the Invention The present invention provides a demountable and relocatable fence comprising: a plurality of support members adapted to releasably locate a plurality of panel members in place, said support members, each including an upstanding member releasably fixable to a base support, the upstanding member being releasable from the base support and coupling members for demounting the fence, said plurality of panel members being adapted to be positioned between said support members and releasably coupled thereto, and said coupling members being fixed to each end of each panel member and adapted to pivotally secure each panel member relative to its corresponding support member.

The present invention also provides a method of erecting a portable, demountable and relocatable fence, comprising: placing one end of at least two panel members adjacent each other such that coupling members fixed to each end of the panel members are substantially aligned, passing a corresponding upright member of the support members through the coupling members, releasably fixing the upright member in a base support.

Preferred embodiments of the present invention will now be described with reference to the accompanying drawings, wherein: Figure 1 is a pictorial view looking from the rear of the complete hoarding of the invention as erected on the site following factory fabrication and transport to the site in an unassembled condition.

Detail A on Figure 1 shows the connection between the removable post member and the panel couplings.

Figure 2 is a pictorial view of the base support system and panel connection with all members separated for clarity.

Figure 3 is a pictorial view from the rear of the hoarding panel showing an alternative light duty support base member and also showing the substitution of a base support member with a tubular post retainer cast into a hole filled with concrete and the diagonal brace pegged to the ground at a lower angle of incline.

4 Figure 4 shows a pictorial view of an alternative base support which can be used in situations where excavation is permitted.

The drawings have omitted alternative finishes to plywood facings for clarity.

The Panels In accordance with the invention, a solid plywood hoarding or chainwire fence panel 1 is factory fabricated as a single unit using rectangular or round steel tubing framing 2 to all four sides of the panel and welded together, to which is attached chain wire fabric or heavy waterproof plywood 3 bottled on to the framing at close centres.

To each end of the panel frame, two short tubular pipe couplings 4 are welded to connect each panel to the support system. The panel height is preferably up to 2 metres and the length is determined by the total weight reasonable for two men to handle.

For building hoardings and partitions the length is 2.4 metres and for chain wire fencing units the length is 4.8 metres. Half and quarter panels may be used to make up total required lengths.

The Support System The unique support system 5 is factory fabricated in three separate parts from steel tubing and rectangular steel sections and consists of a base 6, upright post support 7 and diagonal brace member 8 all designed to interlock with each other and the panel units to form an integral fencing or hoarding system. Section 6D preferably provides additional vertical stability to the support system.

No tools are required and the system can be readily erected, dismantled or relocated by two men.

Concrete counterweights 9 may be located at the end of each base frame to resist wind pressure toppling the fence.

In situations where excavation is permitted as shown in Figure 4, the base support 6 is substituted for a steel tubing retainer 6A cast into a concrete surround 10 in a hole in the ground and the diagonal brace 8 is lengthened to couple or bolt to a steel peg 11 driven into the ground 12. This is generally preferred for longer term applications or where the bearing surface can be excavated.

As shown in Figure 3, the surface tube 6C may be extended beyond the fence panel line in some situations to provide more stability to the fence.

The Interlocking Method of Connection of Panels As shown in Figure 2, the base support 6 is provided with a tubular post retainer 6B which receives the upright post 7 there within.

The post 7 is passed through each of the panel couplings 4 as it is inserted into the base retainer 6B and the final action to assemble the fence is to pass the diagonal brace coupling 4A over the top of the post 7 and lock it to the base support with a suitale connection, such as a bolt/wing nut 13 to the upstand 14 provided on the base support 6.

The whole fence, post and brace members are now securely interlocked together as a total fence or hoarding system.

The panels could be covered with chain wire mesh, fibreglass cast panel facing, timber boarding or iron sheeting without affecting the framing and base support system.

Various finishes can be applied internal and/or external to the panels, for example: The external finish is painted external grade plywood, metal sheeting or chain wire mesh fabric fencing material, The internal finishes would be: 1) painted or stained internal grade plywood, 2) unpainted internal grade plywood faced with vinyl, wool, or synthetic furnishing fabric, 3) unpainted internal grade plywood faced with a vinyl or synthetic sound absorbtion material.

lll~ P- II ~rr~ 6 It is intended that both types of panels could be incorporated in the same hoarding or fence as the connecting and support design for either use is identical.

Claims (8)

1. A demountable and relocatable fence comprising: a plurality of support members adapted to releasably locate a plurality of panel members in place, said plurality of panel members being adapted to be positioned between said support members and releasably coupled thereto, and coupling members being fixed to each end of each panel member and adapted to pivotally secure each panel member relative to its corresponding support member, said support members, each including an upright member releasably fixable to a base support, the upright member being releasable from the base support and coupling members for demounting the fence, each coupling member being formed to extend around its corresponding upright member.

2. A fence as claimed in Claim 1, further comprising a diagonal brace releasably coupled between the upright member and the base support.
