DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a structure for attaching a wire lattice wire mesh to a support post.

[Conventional technology]

A wire grid wire mesh is a wire mesh made of solid steel wire with a diameter of several mm used for vertical and horizontal lines, and is a wire mesh welded by combining the two in a grid pattern and used as a fence around a building or in various other places. It is used. In such a wire-lattice wire mesh, there is one in which a tubular furring strip is formed at the upper end or the lower end.

A conventional mounting structure for this type of wire grid wire mesh is, for example,
No. 57-42056, which is shown in FIGS. 6 and 7.

FIG. 6 shows an example in which the furring strip 2 of the wire grid wire net A used as a fence is attached to the support post 50. In the wire grid wire netting A, the furring strip 2 and the furring strip 2 are formed at the upper end and the lower end. And the furring strips 2 are formed by bending the upper and lower ends of all the vertical lines 3 into circular parts to form ring parts 4 ... The horizontal lines 5 ... Are arranged in parallel. Then, the wire grid wire netting A and the support post 50 are connected by a mounting structure described below.

That is, as shown in detail in FIG. 7, the proximal end portion 9 of the connecting fitting 8 having the arcuate holding piece portion 7 in the short pipe member 6 fitted in the end portion of the furring strip 2 is short. A pair of washer members 10 and 10 inserted into the pipe member 6 and arranged on both front and rear sides of the furring strip 2 so as to straddle the horizontal lines 5 and 5, the short pipe member 6 and the base end portion 9 of the connecting fitting 8. Are fastened together by a bolt 11 inserted through them in the front-rear direction and a nut 12 screwed into the bolt 11, while the holding piece 7 is supported by a support post 50 as shown in FIG. The holding piece portion 7 and the support post 50 are fitted in the front surface portion or the rear surface portion, and are fixed by tightening with a bolt 13 inserted through them in the front-rear direction and a nut 14 screwed into the bolt 13.

[Problems to be solved by the device]

However, the conventional example has the following problems. That is, the connecting metal fitting 8 connecting the short tube member 6 on the furring strip 2 side and the support post 50 is formed by bending a metal plate, and the thickness direction thereof is the front-back direction and the width direction is the vertical direction. Since it is installed so that it is oriented, the wire grid wire mesh A
Not only has a structural defect that the connecting metal fitting 8 is easily bent when pushed back and forth, but there is also a problem that the connecting metal fitting 8 itself has a complicated shape, which makes its bending process difficult.

Further, when fixing the short pipe member 6 and the connecting metal fitting 8 to the furring strip 2, the two washer members 10, 10 are arranged in front of and behind the furring strip 2 and supported by hand, and the washer members 10, 10. 10 and the short pipe member 6 and the bolt at the bolt insertion hole of the base end portion 9 of the connecting fitting 8
Since it is necessary to insert 11 laterally, washer members 10,1
There is a problem that it is troublesome to fix the 0-positional deviation and it takes a lot of time to align the bolt insertion holes, and the fixing metal fitting 8 fixed to the furring strip 2 is fixed to the support post 50. Since the metal mesh A must be lifted and supported at a predetermined height, the connecting metal fitting 8 and the bolt insertion holes of the support post 50 must be aligned with each other, and the bolts 11 and 13 must be laterally inserted therethrough. There is a problem in that workability is poor and a great deal of labor and time are required.

In addition, the washer members 10, 10 and the holding pieces 7 of the connecting fittings 8 are completely visible from the outside and the inside of the fence constituted by the wire lattice wire net A, and the heads of the bolts 11, 13 and the nuts 1
There was also the problem that when looking at the fence from the outside or inside, they were noticeably unattractive because 2,14 protruded in front of and behind the fence.

The present invention has been made in view of the above problems, and in spite of using a mounting member having a simple shape, not only is the strength excellent when the wire grid wire mesh is pushed back and forth, but also the wire grid wire mesh The work of fixing the mounting parts to the furring strip and the work of attaching the wire grid wire mesh to the support posts are excellent, and they are good-looking, and the space between the wire grid wire mesh and the support posts can be easily adjusted. It is intended to provide a structure.

[Means for Solving the Problems]

In the wire grid wire mesh mounting structure according to the present invention, a cylindrical furring strip is formed on at least one of the upper end and the lower end of the wire grid wire netting body, and a pair of horizontal wires are formed at the same height position on the furring strip. Is a wire-lattice wire mesh mounting structure in which the pair of horizontal wires are arranged at both ends of a flat plate portion at the ends of the furring strips. One end of a flat plate-like connecting plate having a bolt insertion hole formed in the elongated hole is fitted between the leg portions projecting downward of the horizontal line and superposed on the horizontal line. One end of the connecting plate is tightened by a bolt vertically inserted into the bolt insertion hole of the flat plate portion of the washer member and the bolt insertion hole of the connecting plate, and a nut screwed into the bolt. While being fixed to a pair of horizontal lines, The other end of the connecting plate projecting from the end of the furring strip is vertically overlapped with the plate-like projecting piece of the receiving fitting projecting on the outer surface of the side wall of the post. The end portion is tightened and fixed by a bolt which is vertically inserted through these bolt insertion holes and a nut which is screwed into this bolt.

[Action]

According to the above configuration, since the width direction of the connecting plate and the protruding piece connecting the furring strip and the support post is the front-back direction and the thickness direction is the vertical direction, the wire-lattice wire mesh pushes back and forth. Demonstrate the strength that can withstand the force of being applied. Moreover, since the connecting plate and the protruding piece are plate-shaped, the shape is simple.

Furthermore, since the washer member and the connecting plate, as well as the bolts and nuts do not project outside or inside the wire lattice wire mesh, they are not so noticeable and look good, and the bolt insertion hole of the connecting plate is a long hole. Therefore, even if the distance between the wire lattice wire mesh and the support post changes, slide the connecting plate before tightening and fixing it with bolts and nuts, and adjust the protruding length from the end of the wire mesh furring strip. The other end of the connecting plate can be reliably overlapped with and attached to the protruding piece of the support bracket of the support post.
