Temporary fences will be erected around the construction site during the construction period for the purpose of ensuring safety inside and outside the construction site and preventing theft.

For example, the one shown in FIG. 6 is known as a normally installed temporary fence.

This temporary enclosure is made by assembling and connecting vertical pipes 21 and horizontal pipes 22 in a grid pattern vertically and horizontally using clamp fittings (not shown), supporting the vertical pipes 21 with supports 23 and fixing them to a fixed surface such as the ground. A plurality of universal steel plates 24 are fixed and attached to a horizontal pipe 22 with bolts and nuts.

[Problem that the invention attempts to solve]

However, in the case of the conventional temporary enclosure, the assembly work of the vertical pipe 21 and the horizontal pipe 22, and the work of assembling the vertical pipe 2
1 to the ground and the universal steel plate 24 to the horizontal pipe 22 were required, making it difficult to assemble easily.

[Purpose of invention]

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a unit type temporary fence that can be easily assembled.

[Means for Solving the Problems] In order to achieve the above object, the present invention has two vertical rod-shaped members having insertion holes at the upper and lower ends and spaced apart from each other at a predetermined interval, and the upper and lower ends of the two vertical rod-shaped members having insertion holes at the upper and lower ends of the upper member. and a post body connected by a lower member, and an upper horizontal bar-shaped member having a plug-in joint at its tip that is rotatably provided on the upper member and inserted into an insertion hole at the upper end of the vertical bar-shaped member at a predetermined length. and a lower horizontal bar-shaped member having a plug-in joint at its tip, which is rotatably provided on the lower member and inserted into the insertion hole at the lower end of the vertical bar-shaped member at a predetermined length, forming a foldable post unit. The upper horizontal bar member and the lower horizontal bar member are placed in a substantially horizontal state to form the folding post unit into a crank shape, a plurality of the folding post units are connected in series to form a ladder-like truss wall, and further, A steel plate having locking portions that are engaged with locked portions provided on the upper horizontal bar member and the lower horizontal rod member is detachably attached to the truss wall.

[Effect of invention]

The operation of the present invention will be explained.

When transporting the foldable post unit constituting the truss wall to a construction site, the vertical bar-shaped member of the post body is overlapped with the upper horizontal bar-shaped member and the lower horizontal bar-shaped member and kept in a folded state.

When assembling a truss wall at a construction site, the upper horizontal bar member and the lower horizontal bar member are placed in a substantially horizontal position, and the folding post unit is shaped like a crank.
With the upper horizontal bar member of one adjacent folding post unit and the lower horizontal bar member of the other folding post unit facing each other, the lower end of the vertical bar member of one folding post unit and the other By connecting the tips of the lower horizontal bar members of the folding post units, and connecting the top ends of the vertical bar members of the other folding post unit and the tips of the upper horizontal bar members of one folding post unit. Continuing folding post units.

After assembling the truss wall, engage the locked parts of the steel plate with the locked parts of the upper and lower horizontal bar members of the truss wall, attach the steel plate to the truss wall, and assemble the unit type temporary enclosure. .

When dismantling a unit type temporary enclosure, the steel plates are removed from the truss wall and the truss wall is disassembled into a plurality of folding post units. Then, the folding post unit is transported in a folded state.

[Embodiment of the invention] Hereinafter, a configuration diagram of a unit type temporary enclosure according to an embodiment of the invention will be explained with reference to the drawings.

A's lower member 7 is rotatably provided, a plurality of ring bodies 8 are attached to one of the rod-shaped members 4A at predetermined intervals as locked parts, and plug-in joints 4C, 4C are attached to both ends of the connecting member 4B. is provided.

As shown in FIG. 1, reference numeral 9 is an accordion-type universal steel plate made of aluminum, and a plurality of L-shaped mounting hooks 9A are attached to the upper and lower ends as locking parts, respectively.

Next, the operation of the present invention will be explained.

As shown in Figure 3, the folding post unit 1
When transporting to a construction site, the upper horizontal rod member 3 and the lower horizontal rod member 4 are stacked on the vertical rod member 5 of the post body 2 and kept in a folded state.

A procedure for assembling a ladder-like truss wall 10 at a construction site by connecting a plurality of the above-mentioned folding post units 1 will be explained with reference to FIGS. 1, 2, 4, and 5.

The upper horizontal rod member 3 and the lower horizontal rod member 4 are placed in a substantially horizontal state as shown in FIG. 2, so that the foldable post unit 1 is shaped like a crank. Then, the first
As shown in Figures 4 and 5, the upper horizontal rod member 3 of one adjacent folding post unit 1 located on the left side and the lower horizontal bar member 3 of the other folding type post unit 1 located on the right side. With the rod-like members 4 facing each other, the insertion joint 4C at the tip of the other lower horizontal rod-like member 4 is inserted into the insertion hole 5B at the lower end of one vertical rod-like member 5 to connect them.

At the same time, the insertion joint 3C at the tip of one upper horizontal bar member 3 is inserted into the insertion hole 5A at the upper end of the other vertical bar member 5, and the adjacent folding post units 1, 1 are connected. , by repeating the above assembly work, the truss wall 1
Assemble 0.

After assembling the truss wall 0, the mounting hooks 9A of the accordion type universal steel plate 9 are engaged with the ring bodies 8 of the upper horizontal bar member 3 and the lower horizontal bar member 4 of the truss wall 0, and the accordion type universal steel plate is attached to the truss wall 0. 9 and assemble the unit type temporary enclosure.

When dismantling the unit type temporary enclosure, remove the accordion type universal steel plate 9 from the truss wall 10,
A truss wall 10 is connected to a plurality of folding post units 1.
Decompose into. Then, the folding post unit 1 is transported from the construction site to the stockyard in a folded state.

According to the above configuration, after all the folding post units 1 are made into a crank shape at the construction site,
Foldable post unit 1 already set on the ground
By stacking adjacent folding post units 1 horizontally in order, a ladder-like truss wall 10 for holding an accordion-type steel plate 9 can be easily assembled.

Furthermore, when attaching the accordion-type steel plate 9 to the truss wall 10, the mounting hook 9A of the accordion-type steel plate 9 can be inserted into the ring body 8 of the truss wall 10, and the fixing work using bolts and nuts as in the conventional example can be eliminated. Moreover, since the accordion type steel plate 9 is made of aluminum, it is light in weight.
Assembly work can be made easier.

Furthermore, since the foldable post unit 1 and the accordion-type steel plate 9 can be folded during transportation, transportation can be facilitated.

In this embodiment, the accordion-type steel plate 9 is made of aluminum, but other materials may also be used, such as reinforced FRP.

Further, in this embodiment, instead of the accordion type universal steel plate 9, a steel plate or sheet of an appropriate width may be used.

Furthermore, in this embodiment, the ring body 8 is provided as a locked part on the upper horizontal bar member 3 and the lower horizontal bar member 4, and the mounting hook 9A is provided as a locking part on the accordion type universal steel plate 9. It is not necessarily limited to this.
