Wire mesh connector

Abstract

This invention provides a wire mesh connector that allows for easy connection of wire meshes without requiring specialized skills, thereby significantly reducing working time. [Solution] The wire mesh connector 1 is inserted into the overlapping portion of wire mesh K1 and wire mesh K2, and placed into the opposing regions of the tip portions 9 and 10 of opposing pieces 2 and 3. Further advance the wire mesh connector 1 to bring the inclined pieces 5 and 6 into contact with wire mesh K1 and K2. Since the inclined pieces 5 and 6 are in an inclined position with their tips facing the support piece 4, they elastically deform in the opening direction when pushed by wire mesh K1 and K2. When wire mesh K1 and K2 pass between the inclined pieces 5 and 6, the inclined pieces 5 and 6 close, and wire mesh K1 and K2 are connected via the wire mesh connector 1.

Description

Technical Field

[0001] The present invention relates to a wire mesh connector for connecting wire meshes arranged on a cliff face.

Background Art

[0002] The slope spraying method described in Patent Document 1 is a method of covering a cliff face and a slope with mortar or concrete. In this slope spraying method, after a wire mesh is attached to the cliff face, mortar or concrete is conveyed via a high-pressure hose or the like and sprayed so as to cover the cliff face together with the wire mesh. Since the area that can be covered by a single wire mesh is limited, it is necessary to connect wire meshes to each other when attaching wire meshes to a cliff face. Therefore, wire meshes are connected to each other by winding a connector formed of a spiral wire around the wire meshes on the cliff face.

Summary of the Invention

Problem to be Solved by the Invention

[0004] However, there is a problem that the work of winding the above-mentioned spiral connector around a wire mesh is extremely time-consuming and furthermore requires skill. Furthermore, the positions where connectors are attached are normally spaced at intervals of 30 cm, and when the area of the cliff face is large, the number of connecting positions of the wire meshes also increases, which requires a considerable amount of working time. In addition, a wire connector wound by hand may not provide sufficient connection strength. If a load is applied to the wire meshes after the wire meshes are connected to each other and before the cliff face is covered with mortar or concrete, there is also a risk that the connection between the wire meshes will come off. This invention was made in view of the above-mentioned conventional problems, and aims to provide a wire mesh connector that allows wire mesh to be easily connected to each other without requiring special skills, significantly reduces working time, and provides sufficient connection strength. [Means for solving the problem]

[0005] The present invention has been made to solve the above problems, and is a wire mesh connector comprising a pair of opposing pieces that face each other and are spaced apart, a support piece continuous with the base ends of the pair of opposing pieces, and inclined pieces provided on the opposing surfaces of the pair of opposing pieces, which are inclined so that their tips face the support piece and their tips come into contact with each other, wherein the pair of opposing pieces are elastically deformable in directions that move them apart and in directions that move them closer together, and furthermore, the inclined pieces are elastically deformable in a state where their tips are separated and open and in a state where they come into contact and closed.

[0006] Preferably, the pair of inclined pieces are formed by making a U-shaped notch in the opposing piece and raising the portion surrounded by the notch.

[0007] Preferably, a bent portion is formed in the intermediate portion between the tip and base ends of a pair of opposing pieces, and the pair of bent portions are bent in a direction that brings the tip ends of the pair of opposing pieces closer together.

[0008] Preferably, the pair of opposing pieces are bent in a direction that causes their tips to move apart from each other.

[0009] Preferably, the edges of the tip sides of the pair of opposing pieces are formed in an arc shape. [Effects of the Invention]

[0010] According to the wire mesh connector of the present invention, it becomes possible to easily connect wire meshes together without requiring any special skills, thereby significantly reducing working time. Furthermore, it becomes possible to obtain sufficient connection strength. [BRIEF DESCRIPTION OF THE DRAWINGS]

[0012] A wire mesh connector 1 according to an embodiment of the present invention will be described with reference to the drawings. As an example, the wire mesh connector 1 is formed of spring steel made of stainless steel with a thickness of 0.3 mm. As shown in FIGS. 1 to 4, reference numerals 2 and 3 denote a pair of opposing pieces, and the base ends of the pair of opposing pieces 2 and 3 are continuous with the end portion on the long side of a rectangular support piece 4 (see FIGS. 3 and 4). Accordingly, the pair of opposing pieces 2 and 3 oppose each other and are provided with a gap therebetween. Edges on the distal end side of the pair of opposing pieces 2 and 3 are formed in an arc shape.

[0013] Inclined pieces 5 and 6 are respectively provided on mutually opposing surfaces of the pair of opposing pieces 2 and 3. The inclined pieces 5 and 6 are in an inclined posture with their distal ends directed toward the support piece 4 side. The pair of inclined pieces 5 and 6 are formed by making U-shaped notches 2a and 3a in the opposing pieces 2 and 3, and raising the portions surrounded by the notches 2a and 3a (see FIG. 6).

[0014] Bent portions 7 and 8 are formed in intermediate portions between the distal end portions and the proximal end portions of the pair of opposing pieces 2 and 3. The pair of bent portions 7 and 8 are bent in a direction in which the distal end side of the pair of opposing pieces 2 and 3 approach each other. Further, the distal end portions 9 and 10 of the pair of opposing pieces 2 and 3 are bent in a direction away from each other.

[0015] Next, a method of using the wire mesh connector 1 will be described. The wire mesh K shown in FIGS. 7 to 9 is what is called a hexagonal mesh, and is widely used in slope spraying construction methods. The wire mesh K is attached to the cliff surface G using an anchor or the like. Since the area that can be covered by one wire mesh K is limited, it is necessary to connect wire meshes K to each other using the wire mesh connector 1.

[0016] In the following description, those disposed on the left side of the wire mesh K are denoted by reference sign K1, and those disposed on the right side are denoted by reference sign K2. As shown in FIGS. 8 and 9, the right end portion of the wire mesh K1 and the left end portion of the wire mesh K2 are brought close to each other so as to overlap. Then, the wire mesh connector 1 is attached to the overlapping portion of the wire mesh K1 and the wire mesh K2. Specifically, as shown in FIG. 10, the wire mesh connector 1 is inserted into the overlapping portion of the wire mesh K1 and the wire mesh K2, and placed into the opposing region of the distal end portions 9 and 10 of the opposing pieces 2 and 3. The edges of the opposing pieces 2 and 3 are formed in an arc shape, and the tip portions 9 and 10 are bent in a direction that separates them from each other. This prevents the wire mesh K1 and K2 from hitting the tip portions of the opposing pieces 2 and 3, and allows for smooth insertion of the wire mesh connector 1.

[0017] Furthermore, as shown in Figure 11, the wire mesh connector 1 is advanced so that the inclined pieces 5 and 6 come into contact with the wire meshes K1 and K2. Since the inclined pieces 5 and 6 are in an inclined position with their tips facing the support piece 4, they elastically deform in the opening direction when pressed by the wire meshes K1 and K2. Then, when the wire meshes K1 and K2 pass between the inclined pieces 5 and 6, the inclined pieces 5 and 6 close as shown in Figure 12, and the wire meshes K1 and K2 are connected via the wire mesh connector 1 (see Figure 9). In this way, by using the wire mesh connector 1, wire meshes K1 and K2 can be easily connected without requiring any special skills. Therefore, it becomes possible to significantly reduce working time.

[0018] Furthermore, in the above operation, the opening and closing of the pair of opposing pieces 2 and 3 is performed using the bent portions 7 and 8 as pivot points. Compared to the case where the base ends of the opposing pieces 2 and 3 are used as pivot points, the opposing pieces 2 and 3 are less likely to open, and the wire mesh connector 1 can be prevented from coming off the wire mesh K1 and K2. In particular, when attaching wire mesh K to a large cliff face G, the period between attaching the wire mesh K and covering the cliff face G with mortar or concrete becomes long, and the wire mesh K may be subjected to stress during that time. Even in such cases, as described above, the opposing pieces 2 and 3 are difficult to separate, so it is possible to prevent the wire mesh connector 1 from coming off the wire mesh K1 and K2.

[0019] Although embodiments of the present invention have been described in detail above, the specific configuration is not limited to these embodiments, and any design changes or other modifications that do not depart from the spirit of the invention are also included in the invention. In the above embodiment, a spring steel made of stainless steel was shown, but the present invention is not limited thereto, and other types of spring steel made of iron may be used. Also, although the wire mesh connector was constructed using spring steel with a thickness of 0.3 mm, the present invention is not limited thereto, and the thickness is not limited to 0.3 mm. [Industrial applicability]

[0020] The wire mesh connector of the present invention has potential applications in the manufacturing industry of wire mesh connectors and the like. [Explanation of Symbols]
