Description

[Detailed description of the invention] The present invention relates to an improvement of a fence in which a tensioning material such as a wire mesh with a frame is stretched between each support, and it is possible to extremely easily and reliably connect the tensioning material to the above-mentioned support at any relative position. It is characterized by the fact that it has done so.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In Fig. 1, 1, 1, . . . . shows a framed wire mesh in which a wire mesh frame 4 is attached around a wire mesh 3 as an example of the tensioning material.

A pair of support pieces 5, 5 having oblique elongated holes 6 are provided at appropriate positions on the upper and lower sides of the support column 1, respectively, with a fixed gap maintained between them. At the side ends of the supporting pieces 5, 5 are provided at positions corresponding to the supporting pieces 5, 5.
A connecting portion 7 is provided with an oblique elongated hole 8 that is inclined in the opposite direction to the oblique elongated hole 6 . A large number of locking recesses 9 and 10 are formed respectively, and the connecting portion 7 is fitted between the pair of support pieces 5, 5, and the bolts 11 inserted into both inclined elongated holes 6, 8 are respectively inserted. They are connected by locking into the recesses 9 and 10 and tightening with a nut 12.

The pair of support pieces 5, 5 can move the connecting part 7 in the direction of the inclined elongated holes 6, 8 when the bolt/nut is temporarily tightened, and can also move the connecting part 7 when the bolt/nut is strongly tightened. It is formed so that it can be clamped and fixed in an immovable state, and each of the above-mentioned oblique elongated holes 6 and 8 allows the bolt 11 to be inserted into the recess 9.
, 10 is formed in the hole so that it can be moved freely while being pressed against the edge of the hole on the side where the holes are not provided.

The inclined elongated holes 6 and 8 in the support pieces 5, 5 and the connecting portion 7 may be inclined in the opposite direction to each other than shown in the figure, or the inclined elongated holes 6 and 8 in the supporting pieces 5, 5 and the connecting portion 7 located above and below may be oppositely inclined. The holes may be provided in opposite directions.

When connecting the above-mentioned framed wire mesh 2 between the supports 1, 1,
Each connecting portion 7 is fitted between the corresponding support pieces 5, 5, and they are temporarily fastened with bolts 11 and nuts 12 inserted into the oblique elongated holes 6, 8, and the position and posture of the framed wire mesh 2, etc. After adjusting, firmly tighten the bolts and nuts to secure them.

In the temporarily fastened state, the connecting portion 7 is able to move between the support pieces 5 and 5 in the direction of the inclined elongated holes 6 and 8, but due to the load of the framed wire mesh 2 acting on the bolt 11, the bolt 11 are engaged with the recesses 9 and 10 of the respective oblique elongated holes 6 and 8, therefore, unnecessary movement of the connecting portion 7 is prevented, and the frame wire mesh 2 naturally shifts its position after adjustment. There is no such thing.

In addition, when adjusting the position of the framed wire mesh 2, the bolts 11 are inserted into the recesses 9 and 1 of the inclined elongated holes 6 and 8 by supporting the load.
0 and move the bolt 11 to the required position along the oblique oblong hole 6° 8. There, the bolt 11 locks into the recesses 9 and 10, and the framed wire mesh 2 is moved to its position. Stably supported in position.

When the bolts 11 are strongly tightened, the wire mesh 2 with a frame is fixed very stably because they are locked in the recesses 9 and 10 of the respective oblique long holes 6 and 8. That will happen.

As detailed above, according to the fence according to the present invention, locking recesses are formed on the edges of the oblique elongated holes for connecting the support and the tensioning material, and the locking recesses are inserted into both of the oblique elongated holes. Since the bolts are locked in the recesses mentioned above, it is possible to prevent the tension material from shifting, etc., and to connect and fix it very stably.Furthermore, when adjusting the position of the tension material during temporary tightening, it is possible to prevent the tension material from shifting. By locking the bolt into the recess, unnecessary movement of the tension material after adjustment can be reliably prevented, and the connection work can therefore be performed very easily. It is formed only on one edge of the oblique oblong hole, and is large enough to allow the bolt inserted through the oblique oblong hole to move freely while pressed against the edge of the hole on the side where the recess is not provided. Since the recess is formed in a straight line, the position adjustment while supporting the load of the tensioning material can be smoothly and easily performed without causing the temporarily fastened bolt to fit into the recess.
