Description

  TECHNICAL FIELD The present invention relates to a plurality of grid-like members, such as a welded wire mesh or a net-like fence, buried in concrete, in which vertical and horizontal members are formed in a grid.

  When casting concrete to construct a structure such as the floor of a building, to increase the strength of the structure and prevent cracks from occurring in the structure, a plurality of welding meshes are placed in the concrete. It is buried.

  FIG. 15 is an explanatory view for explaining a conventional method of constructing a welding wire mesh, in which WM is a welding wire mesh. The welding wire mesh WM is composed of a plurality of vertical strips W1, W1,... And horizontal strips W2, W2,. Are fixed to each other by welding.

  A not-illustrated formwork is erected around the construction target area, and a plurality of welded metal meshes WM, WM,... Are laid all over the formwork. At this time, the edges of the adjacent welding wire meshes WM, WM overlap each other by a plurality of squares (one square in FIG. 15). Next, as shown in FIG. 15, spacers 30, 30,... Are interposed between the construction target surface and the welding meshes WM, WM,. Lift by the specified dimension. Then, in order to prevent mutual displacement from occurring even when the worker who works on the welding wire mesh steps on the overlapping portion of the adjacent welding wire meshes WM, WM, for example, a short wire such as a wire is used. Are bound together by the binding members B, B,... Using the strip members.

  After the construction of the welding meshes WM, WM,... Is completed in the construction target area in this manner, concrete is poured into the formwork to a predetermined depth at which the welding meshes WM, WM,. Level the surface.

  However, such a binding operation needs to be performed on the four sides of each of the welded metal meshes WM, WM,..., And since there are many binding points on each side, a structure having a relatively large area is required. In the case of construction, in addition to the need for a plurality of skilled workers, even a skilled worker takes a long time to complete the work at all the binding locations.

  Therefore, Patent Literature 1, which will be described later, proposes a joining device that joins ends of members forming adjacent welding meshes in a straight line without overlapping the welding meshes. By using such a joining device, an inexperienced worker can perform joining work.

JP-A-51-5818

  However, when joining adjacent welded meshes using such a joining apparatus, the ends of the respective strips constituting the adjacent welded meshes must be aligned linearly, and such alignment is required. In addition to the time required for the operation, there is a problem that the operation of joining the ends of the strips by the joining device requires a relatively long time.

  The present invention has been made in view of such circumstances, and provides a lattice-like body that can be reliably interconnected in a short time even by an unskilled worker.

At this time, since another grid-like body can be fixed to the fixing portion without performing the conventional binding work, even an unskilled worker can surely interconnect with each other in a short time. Further, the fixing portion can be made of the same material as the vertical and horizontal members, and in such a case, even if buried in concrete, it is not regarded as a foreign substance. Further, since a horizontal or vertical strip of another grid-like body is sandwiched between the fixing portion and the vertical or horizontal strip, the overlapped portion of the two grid-like bodies is formed. Therefore, there is no danger that the fixing of the two lattice-shaped members will be released even if the worker performs the work.
