Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a shape-holding device for transporting folded wire mesh.

<Prior art> Generally, as shown in FIG. 2, a first mesh member A1 and a second network member A2 having jagged portions B1 and B2 bent in opposite directions are sequentially knitted. When transporting a 2m wide wire mesh from the factory to the construction site, as shown in Fig. 3, the first mesh component A1 and the second mesh component A2 are tightly folded so that the first mesh component A1 The first end rings C1 at both ends of the net member A2 and the second end rings C2 at both ends of the second network member A2 are shifted from each other. At this time, the number of the first end ring C1 and the second end ring C2 is about 22 to 23 each, but when the wire mesh is expanded as shown in Figure 2 during construction, the first end ring C1 and the second end ring C2 are There is a problem that it interferes and is difficult to expand.

<Purpose> The present invention is capable of holding the first end ring and the second end ring in sections in an extremely short time, and eliminates the problem that the first end ring and the second end ring interfere with each other when expanding the wire mesh during construction, making it difficult to expand. The purpose of the present invention is to provide a folding wire mesh transportation shape holding device that can solve the problem.

<Example> Hereinafter, an example of the present invention will be described based on FIG. The constituent materials A2 are knitted one after another, and the first net constituent material A1 and the second net constituent material A2 are tightly folded to form a first end ring C1 at both ends of the first net constituent material A1 and a second net structure. Second end rings C2 at both ends of material A2
A pair of U-shaped holding wire rods 1 (the wire diameter is 1.6 to 2.0 mm), each first straight portion 1a of the pair of holding wires 1 is inserted into the first end ring C1 at both ends of the first network member A1, and each second straight portion 1b is Both ends of the holding wire inserted through the second end rings C2 at both ends of the double mesh component A2 and protruding outward from the first end ring C1 and the second end ring C2 are bent to form retaining parts 1d and 1e. It is something that

Next, how to use it will be explained. First, when transporting from the factory to the construction site, a straight holding wire 1 is prepared for both ends of the folded wire mesh shown in Fig. 3, and the central part is bent by hand to form the engaging part 1c. By doing so, the entire body is formed into a U-shape, and while holding this engaging portion 1c by hand, the first straight portion 1a thereof is inserted into the first end ring C1 of the first network component A1, and the second straight portion Insert the portion 1b into the second end ring C2 of the second network member A2, and then bend it by hand while pulling both ends protruding outward from the first end ring C1 and the second end ring C2. Then, the retaining portions 1d and 1e are formed. The folded wire mesh is then packaged as necessary, piled up in large numbers on a truck, and transported to the construction site.

When installing, first bend the retaining parts 1d and 1e into a straight shape by hand, and then pull out the holding wire 1 while it is inserted or by holding the engaging part 1c by hand, and then remove the first end. The first network component A1 or the second network component A2 located on the upper side in the direction of eliminating misalignment between the ring C1 and the second end ring C2 and slightly floating.
While expanding the entire first network component A1 and second network component A2 by pulling the first network component A1 and second network component A2 located at the ends in the folding direction, the second network component A1 and second network component A2 are expanded. As shown in the figure, during this expansion process, the positions of the first end ring C1 and the second end ring C2 are held by the holding wire 1 and do not collapse during transportation.
Even if the holding wire 1 is removed, the two do not interfere with each other and make it difficult to spread.

Then, wire rods having approximately the same diameter as the first and second network members A1 and A2 are passed through the first end ring C1 and the second end ring C2, and then the first end ring C1 and the second end ring C2 are The fence is assembled by being inserted into the horizontal aggregate of the fence.

<Effect of the invention> Therefore, according to the invention, the positions of the first end ring and the second end ring are held by the holding wire during transportation and do not collapse during the expanding process, so that they do not interfere with each other and are difficult to expand. Never. In other words, the first end ring and the second end ring can be separated and held in a very short time, and the problem of the first end ring and the second end ring interfering with each other when expanding the wire mesh and making it difficult to expand can be solved. .
