The position of the second frame member is different from that parallel to the second frame member, so that the second frame member of the fixture to which the two lattice members of the overlapping portion are fixed is embedded in one lattice member. Thus, the first frame of the fixture protrudes from the surface of the one grid-like body. Thereby, when it fixes with a grid | lattice-like body, it can reduce that a fixing tool protrudes from the surface of one grid | lattice-like body. Note that coupling means are provided at both ends of the second frame member, and both the first frame members intersect with the circumferential direction of both the second frame members and the direction in which the bent portion of the coupling means is bent.

(First embodiment for carrying out the invention)
FIG. 1 is a perspective view showing an example of a fixture according to the present invention. The fixture 1 includes a pair of rod-shaped first frame members 11, 11 and rod-shaped second frame members 12, 12 having a predetermined dimension shorter than the first frame member 11, and the first frame members 11, 11. First coupling means 11b, 11b, 11b, and 11b for coupling a plurality of superposed welded wire meshes to each other are provided at both ends of each. Here, the first frame members 11 and 11 and the second frame members 12 and 12 are made of the same material as the welded wire mesh to be constructed. Further, the diameters of the first frame members 11 and 11 and the second frame members 12 and 12 are usually appropriately dimensioned to be equal to or smaller than the diameter of the strip material constituting the welding wire mesh to be constructed. In some cases, the dimension exceeds the diameter of the strip.

As shown in FIG. 1, the paired first frame members 11, 11 are arranged in parallel to each other at a predetermined distance. Further, the second frame members 12 and 12 are arranged in parallel with each other at a predetermined distance at a midway position in the longitudinal direction of the first frame members 11 and 11 in a posture orthogonal to the first frame members 11 and 11. The second frame members 12, 12 and the first frame members 11, 11 are fixed to each other by welding or the like. The dimensions of the portion surrounded by the first frame members 11 and 11 and the second frame members 12 and 12 are substantially the same as the dimensions of the mesh M (see FIGS. 6 and 7) of the welded wire mesh WM described later. It is.

The first coupling means 11b described above is bent in a direction intersecting with the plane connecting the main bodies 11a, 11a excluding the first coupling means 11b, 11b, 11b, 11b of the first frame members 11, 11, The frame members 12, 12 have their peripheral surfaces fixed at the same positions as the positions of the bent portions of the first coupling means 11b, 11b in the circumferential direction of the first frame members 11, 11. Both the second frame members 12 and 12 are arranged on one surface side of the plane connecting the opposed first frame members 11 and 11.

In the present embodiment, the case where the peripheral surfaces of both end portions of the second frame member 12 are fixed to the peripheral surface of the first frame member 11 is shown, but the present invention is not limited to this, and the second frame member is not limited thereto. You may fix the both end surfaces of 12 to the surrounding surface of the 1st frame members 11 and 11. FIG. Further, in the present embodiment, the second frame members 12, 12 are arranged at appropriate positions in the longitudinal direction of the first frame members 11, 11, in the circumferential direction of the first frame members 11, 11, and in the first coupling means 11 b, Although shown about the case where it fixes to the same position as the position of the bending part of 11b, the 2nd frame members 12 and 12 are the surrounding surfaces of the 1st frame members 11 and 11, Comprising: In the circumferential direction of the 1st frame member 11 The first coupling means 11b, 11b may be fixed by changing the position of 180 ° from the position of the bent portion.

2 to 4 are a partially enlarged side view, a partially enlarged bottom view, and a partially enlarged front view showing the first coupling means 11b shown in FIG. 1 and the vicinity thereof. In these drawings, parts corresponding to those shown in FIGS. 1 and 2 are denoted by the same reference numerals.

As shown in FIG. 2, the first coupling means 11 b is bent from the main body 11 a of the first frame member 11, which is the base end thereof, in the side view, and further, the bent portion P is formed. As shown in FIG. 4, it is bent around the center axis of the main body 11a when viewed from the front. The bending posture of the bent portion P can be set as appropriate. In the fixture 1 shown in FIG. 1, the first coupling means 11 b and 11 b at both ends of the first frame member 11 are the first frame member 11. The first coupling means 11b, 11b, 11b, 11b at one end of the paired first frame members 11, 11 are arranged in the same direction around the central axis of the main body 11a. , 11 in different directions around the central axis of the main bodies 11a, 11a.

Further, as shown in FIG. 3, the first coupling means 11b has a hook portion f formed by bending around an axis L which is parallel to the central axis of the main body 11a of the first frame member 11 which is the base end in the bottom view. The hook portion f has a curvature that substantially follows the outer peripheral surface of the longitudinal or transverse member of the welded wire mesh to be coupled thereto. Thereby, the 1st coupling | bonding means 11b can be made to fit the vertical strip | belt material or horizontal strip | belt material of a welding wire mesh in the hook part f of the said 1st coupling | bonding means 11b so that it may mention later.

On the other hand, as shown in FIG. 4, the front end of the first coupling means 11 b is a slope S in front view, and the slope S and the vertical strips or the horizontal strips constituting the welding wire mesh to be constructed are used. The angle α formed by the parallel surface M that is parallel to the surface to be formed is approximately 45 °. As a result, as will be described later, when the first joining means 11b joins the vertical or horizontal strip of the welding wire mesh to be constructed, the slope S comes into contact with the vertical or horizontal strip of the welding wire, Since the slope S slides on the vertical strip or horizontal strip of the welding wire mesh, the vertical strip or horizontal strip of the welding wire mesh can be easily fitted into the hook portion f of the first coupling means 11b. The joining operation can be carried out smoothly.

Here, the inner height H of the first coupling means 11b is, for example, as shown in FIG. 2, the horizontal strip W2 constituting the superimposed one welded wire mesh WM, and the other welded wire mesh WM. Are arranged in the order of the horizontal strip W2 that constitutes the vertical strip W1, the second frame member 12 that constitutes the fixture 1, and the first frame member 11, and the one of the ones into the hook portion f of the first coupling means 11b. When inserting the vertical strip W1 of the welded wire mesh WM, the diameter of the vertical strip W1 of one welded wire mesh WM, the diameters of the horizontal strip W2 and the vertical strip W1 of the other welded wire mesh WM, fixed The diameter of the second frame member 12 of the tool 1 is slightly larger than the total value. As a result, the vertical strip W1 of one welded wire mesh WM inserted into the hook portion f of the first coupling means 11b is connected to the vertical strip W1 of the other welded wire mesh WM and the horizontal strip W2. Second frame member 12—Because it is fixed between the main body 11a of the first frame member 11 and the tip of the first coupling means 11b, the vertical strip W1 of one welded wire mesh WM is extracted from the hook portion f. It is prevented.

On the other hand, the vertical strip W1 constituting the superposed one welded wire mesh WM, the horizontal strip W2 constituting the other welded wire mesh WM, and the second frame constituting the fixture 1. When the member 12 and the first frame member 11 are arranged in this order, and the horizontal strip W2 of one welded wire mesh is fitted into the hook portion f of the first coupling means 11b, the inside of the first coupling means 11b The high dimension H is the diameter of the horizontal strip W2 and the vertical strip W1 of one welded wire mesh WM, the diameter of the horizontal strip W2 and the vertical strip W1 of the other welded wire mesh WM, and the second frame of the fixture 1. The diameter of the member 12 is slightly larger than the total value. In such a case, the second relative to the first frame members 11, 11 of the fixture 1 is different so that the horizontal strip W2 of the other welding wire mesh WM and the second frame member 12 of the fixture 1 are different. It is good to adjust the attachment position of the frame members 12 and 12 beforehand.

In the case shown in FIG. 2, the vertical strip W1 of one welded wire mesh WM is fitted into the hook portion f of the first coupling means 11b, but the present invention is not limited to this. Instead, the horizontal strip W2 of one of the welded wire meshes WM may be fitted into the hook portion f of the first coupling means 11b.

Accordingly, the inner height H of the first coupling means 11b is determined by the number of welded wire meshes WM to be overlapped and the vertical or horizontal strip material that is inserted from the first frame member 11 into the hook portion f of the first coupling means 11b. Is determined by the distance to.

By the way, although the horizontal strips W2 and W2 are opposed to each other, the welding wire meshes WM and WM can be arranged so as to be different from each other, but in such a case, the inner height H of the first coupling means 11b. Are adjusted accordingly.

Next, a method for fixing a plurality of welded wire meshes using the fixture according to the present invention will be described.
