Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a connection structure between a post and a wire lattice fence body, and more specifically, the present invention relates to a connection structure between a support and a wire lattice fence body. This relates to a structure in which a wire lattice fence body, which is constructed by arranging and welding a required number of horizontal stripes in a lattice shape on the upper and lower annular portions and flat portions in parallel at arbitrary intervals, is connected to the pillars. The invention is an improvement of Utility Model Application No. 1983-80218, which was previously filed by the inventor of the present application.

[Conventional technology]

Although not shown, the connection structure between the pillars and the wire lattice fence body according to Utility Model Application No. 59-80218 is characterized in that, although not shown, a slightly long symmetrical piece is attached to both ends of an arc-shaped holding piece that fits the outer peripheral surface of the pillar. A pair of connecting metal fittings having outwardly curved pieces are made to face each other, and the holding pieces are held on the pillars and tightened and fixed with bolts and nuts. The two parts are respectively inserted into the cylindrical rim of the wire lattice fence body, and a pair of metal holding plates each having a U-shaped cross section are respectively engaged with at least two horizontal rods on the cylindrical rim from both outside sides of the cylindrical rim. The wire lattice fence body is connected to the wire lattice fence body by disposing the wire lattice fence body facing the outwardly curved piece and screwing the screw into the threaded hole in the outwardly curved piece through the hole in each fitting holding plate.

[Problem that the invention attempts to solve]

By the way, although the connection structure according to Utility Model Application No. 59-80218 can provide a strong connection, the following two problems have occurred in its installation work.

If the opposite side to which the wire lattice fence body is attached is a river, the sea, a rock wall, etc., the metal fitting retaining plates must be screwed from both outsides of the cylindrical rim of the wire lattice fence body, so it is difficult to install the wire lattice fence body from the river side. Screwing is very time-consuming and dangerous, and in particular, the higher the fence, the worse the workability becomes.

If the pillars are embedded and erected in advance, the connecting fittings will protrude from both sides of the adjacent pillars, making it impossible to set the wire lattice fence body between the pillars and making it impossible to install.

The present invention has been made to solve these two problems.

Therefore, the object of the present invention is to be able to easily and safely connect wire lattice fence bodies even if the opposite side is a river etc. Also, the wire lattice fence body can be easily and firmly connected.
