Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> This invention relates to a lath for construction and construction.

<Problems to be solved by this device> In order to allow a welding iron wire attached to one surface of a lath or a rib lath to be freely bent without returning and repulsing, it was replaced with an annealed iron wire. Was previously proposed in Japanese Utility Model Publication No. 60-23383.

However, since the annealed iron wire proposed by the above-mentioned publication is a round rod having a circular cross section, when welding lath and rib lath to the base material, there is a large gap between both sides of the annealed iron wire and the base material. There was a problem that it took a long time to weld and attach the welding material to the welding and the welding amount required a lot of time, and if welding was continued for a long time, the annealed iron wire was melted and cut by the heat accompanying welding. . If the above iron wire is thickened to avoid these, there is a problem that the weight is increased and the handling of lath and rib lath becomes difficult. The present invention is intended to solve such a problem.

<Construction of the Invention> The present invention is equipped with an annealed iron wire for welding, which has an elliptical or thin flat cross section and is longitudinally and laterally spaced on one surface of a lath or a rib lath, and has a longitudinal interval at each of the annealed iron wires. Architecture characterized by having multiple circular holes for welding,
Located on the construction lath.

<Operation> In the present invention, an annealed iron wire that does not rebound when bending is installed at intervals in the longitudinal and lateral directions on one side of the lath and rib lath. It can be bent and attached to a base such as a prism without sagging, and since the annealed iron wire has a wide shape with an elliptical or thin flat shape, the lath and rib lath can be used as a base without increasing the weight. The gap between them is made small to facilitate welding attachment, and there is no need to create a spot where the annealed iron wire melts and cuts during welding, and a wider shape can form a relatively large circular hole in the annealed iron wire. By welding to the substrate using a circular hole with a 360-degree hole, it is possible to securely perform welding at a predetermined position.
There will be no part where the rib lath is partially lifted from the base.

<Example> An example will be described below with reference to the drawings.

FIG. 1 shows a lath 3 formed in a vertically long quadrangular shape having an infinite number of stitch gaps 2 between thin metal wires 1. The lath 3 has a thickness of about 1.2 mm in the longitudinal direction at the left and right ends of one surface and a width. Annealing iron wires 4a, 4b having a thin cross section or an elliptical shape with a diameter of about 15 mm are attached by spot welding, and annealed iron wires 4c of the same kind are attached at intervals in the lateral direction between the iron wires 4a, 4b. FIG. 2 shows a rib lath 6 in which the rib 5 is provided in the middle by non-punching in forming the lath, and one side of this rib lath 6 has the same arrangement of the annealed iron wires 7a to 7c as described above. Install.

Then, the annealed iron wires 4a to 7c are annealed literally in advance so that they can be freely and easily bent without returning and repulsing.

Further, as shown in FIGS. 3A and 3B, each of the annealed iron wires 4a to 7c has a plurality of circular holes which are spaced in the longitudinal direction and are as large as possible in any of the thin flat section a and the elliptical section b. Ha is provided.

Now, when mounting the lath 3 along, for example, a metal-made prismatic surface 9 that projects from the wall surface 8, the lath 3 is applied to the portions of the annealed iron wires 4a to 4c with the mounting surfaces of the annealed iron wires 4a to 4c facing outward. It is welded to the wall surface and prismatic surface. At the portion of the circular hole c, a welding surface can be obtained at 360 degrees along the hole of the circular hole c.

In this way, the lath 3 is welded and attached to the one surface 9a of the prismatic base material 9 following the wall surface 8, and then the portion protruding from the one surface 9a of the lath 3 is sequentially bent along the corner surface 9b into the two surfaces 9c and 3d. Welding is installed in the same manner as above. At this time, since the annealed iron wires 4a to 4c can be freely bent without returning and repulsing due to annealing, the lath bends as the annealed iron wire 4c is bent and is well attached to the prismatic surface 9 as the base.

<Effects of the Invention> As described above, according to the present invention, the annealed iron wires are attached at intervals in the vertical and horizontal directions on one surface of the lath and the rib lath.
Regardless of the size, the rib lath can be bent and attached along the foundation for wall surface formation without sagging in both vertical and horizontal directions and without rebound and rebound. Since the cross-section has an elliptical shape or a thin flat shape, it does not increase the weight of the lath and rib lath, and both sides of the annealed iron wire can be made to face each other with a small gap on the base, allowing the welding material to melt and fill. Welding can be done in a short time with a small amount of coating, and there is an effect that lath and rib lath can be easily and surely attached to the base without making a place to melt and cut the annealed iron wire by heat during welding. .

Furthermore, by forming the annealed iron wire into a wide shape, a relatively large circular hole can be formed in the middle of the annealed iron wire.
Welding with a wide range of holes produces the effect that the lath and rib lath do not form a portion that floats away from the base.
