Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to the improvement of wire mesh fences.

[Prior Art] In a conventional wire mesh fence, the upper and lower ends of a diamond-shaped wire mesh are attached to the upper and lower edges of the posts via connecting fittings, and plate-shaped locking rods are attached to the side edges of the wire mesh. The upper and lower ends of the locking rod are screwed to the upper and lower connecting fittings, or the locking holes provided in the connecting fittings are locked to cut-and-raised holes, etc., to support the rod. Because it is necessary to provide a flange portion for holding the locking rod in the connecting metal fitting, a screw mounting hole, a locking hole, a cut-out, etc., the structure of the connecting metal fitting becomes complicated and processing becomes troublesome. Ta.

[Problems to be Solved by the Invention] An object of the invention is to provide a wire mesh fence in which the locking rods can be easily and reliably supported by the connecting fittings.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention constructs a frame through connecting fittings above and below the pillars erected at regular intervals, and connects the upper and lower ends to the frame. A plate-shaped locking rod is attached to the side edge of the clothed wire mesh, and the upper and lower ends of the locking rod are inserted and locked into the grooves of the upper and lower connecting fittings. A locking rod can be inserted by providing one or a pair of tongue pieces protruding from the groove edge of the split groove in the upper connecting fitting forming the upper connecting fitting, and bending one of the tongue pieces or the pair of tongue pieces upward. In addition to providing a gap for use, the bent tongue piece constitutes a retaining part that prevents the locking rod from moving in the width direction of the split groove, and the other of the one tongue piece or the pair of tongue pieces is formed. The tongue piece is inserted and locked into a locking hole bored at the end of the locking rod.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.
2 and 3 are struts erected on the ground at regular intervals, and rims 2 and 3 are installed above and below the pillars 1 via connecting fittings 4 and 5, and wire mesh is attached to the lower or upper surface of the rims 2 and 3. Insertion grooves 6 and 7 are provided, and the upper and lower ends of the diamond-shaped wire mesh 8 are inserted and locked into the insertion grooves 6 and 7.

As can be seen from FIGS. 3 and 4, the connecting fittings 4 and 5 are provided with split tube-shaped support connecting portions 9 and 10 and body edge connecting portions 11 and 12, and these connecting portions each have a By fitting the strut 1 and the rims 2, 3 and attaching bolts 13, 14 at positions away from the rims 2, 3 in the rim connecting parts 11, 12, the strut 1 and the rims 2, 3 are attached. The upper connecting fitting 4 is formed into a half-shape by providing the dividing groove 15 only in the lower half, while the lower connecting fitting 5 has the dividing groove 16 in the upper half. By providing it on the lower surface, it is divided into two metal fitting pieces 5a, 5a.

The dividing groove 1 in the connecting fittings 4 and 5 is
A pair of locking tongues 17, 17, 18, 18 protruding into the split grooves are provided on the groove edges of 5 and 16, and the upper connecting fitting 4 is provided with As shown, a gap 22 is provided between the pair of tongues 17 by bending one of them.

On the other hand, plate-shaped locking rods 19 oriented parallel to the wire mesh surface are inserted and engaged with the row lines at the side ends of the wire mesh 8, and the upper and lower ends of the locking rods 19 are connected to the connecting fittings 4, The tongue pieces 17 and 18 are inserted into the grooves 15 and 16 of No. 5, and the tongue pieces 17 and 18 are inserted and locked into the locking holes 20 and 21 formed in the locking rod 19.

When actually installing the locking rod 19, insert the upper end of the locking rod 19 into the split groove 15 of the upper connecting fitting 4 through the gap 22, and lock the unbent tongue piece 17. The rod 19 is inserted and locked into the locking hole 20, and the bent tongue piece 17 is brought into contact with the side surface of the locking rod 19, and the bent tongue piece 17 locks the rod. A retaining portion is configured to restrict movement of the rod 19 in the width direction of the groove 15 and prevent it from coming off from the groove 15.

On the other hand, in the lower connecting metal fitting 5, the two metal fitting pieces 5a, 5a are butted together so that their tongue pieces 18, 18 are inserted into the locking hole 21 of the locking rod 19, and in this state, both metal fitting pieces 5a , 5a may be tightened with bolts 14.

FIG. 5 shows another embodiment of the upper connecting fitting 4,
In this embodiment, a tongue piece 23 is provided at only one groove edge of the split groove 15 in the insertion gap 24 of the locking rod 19, and the locking rod 19 is locked to the tongue piece 23, and the locking rod is attached to the tip of the tongue piece 23. 19 is provided with a bent edge 23a that constitutes a retaining portion to prevent it from being pulled out.

Furthermore, in the embodiment shown in FIGS. 6A and 6B, the tongue piece 2
5 as a whole, and the tip part of the tongue piece 25 is made into a narrow part 25a.
is inserted into the locking hole 20 of the locking rod 19.

Note that the tongue piece 17 of the lower connecting fitting 5 may also be provided only on one groove edge of the split groove 16.

[Effect of the invention] According to the wire mesh fence of the invention having the above configuration, a gap for inserting a locking rod is provided by bending the tongue protruding from the groove edge of the upper connecting fitting, and the bending The tongue piece forms a retaining part that prevents the locking rod from moving in the width direction of the split groove and coming off, so that the connecting fitting cannot push the two-part part apart. Even if the locking rod is highly rigid and sturdy, the locking rod can be easily inserted into the split groove and the tongue can be inserted and locked into the locking hole. The locking rod is prevented from shifting in the width direction of the split groove by the retaining portion, and it is possible to reliably prevent the locking rod from rattling or coming off from the tongue piece.

Furthermore, by simply bending the tongue piece, the insertion gap and the retaining part can be formed at the same time, so the structure and manufacture of the connecting fitting are simple.
Furthermore, since there is no need to screw the locking rod and the connecting fitting together, it has excellent features such as easy and quick assembly work.
