DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lath for forming a gap, and more particularly, when a large or small gap is formed between an H-section steel and a vertical wall in the construction process of a building or a building, the gap is replaced with rock wool. The present invention relates to a lath stretched for supporting the base material so as to close the base material by spraying or painting.

[0002]

2. Description of the Related Art Japanese Unexamined Utility Model Publication No. 6-4237, filed by the present applicant, discloses this type of technique. The publication discloses that a braided lath composed of a thin metal wire is provided with waves with alternating protruding strips on both sides, and an annealed iron wire having a thickness that can be welded perpendicular to the protruding strips on one side of the lath is provided. It describes a lath for extending a gap, characterized in that a plurality of laths are placed and attached.

[0003]

However, in this publication, one end of the lath is welded and attached to the H-section steel flange portion using an annealed iron wire. However, there is a problem that a worker skilled in welding technology must be dispatched, and there is a problem that it is not easy to stretch the lath.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a face-to-face holding member which can be cut and adjusted by the lath and a strip-shaped iron plate is formed on the entire length of one end of the lath, and is held between flange portions of an H-shaped steel. This problem was solved by stopping and fastening.

[0005]

According to the present invention, one end of the lath is clamped and fastened to the flange portion of the H-beam by means of a facing clamping piece provided at one end of the lath, and the other end of the lath is inserted into a groove provided on a vertical wall or the like. Alternatively, the lath is stretched in the gap formed between the H-section steel and the vertical wall or the like by folding or butting against the vertical wall. When the lath is long in relation to the length of the gap, the lath is cut together with the pinching piece to adjust the length.

[0006]

An embodiment will be described below with reference to the drawings.

FIGS. 1 and 2 show a first embodiment of a cutable lath 2 having a narrow rectangular shape and having a wave 1 in which a concave curved surface 1a and a convex curved surface 1b alternate in the narrow direction. Similarly, a strip-shaped iron plate 3 that can be cut is placed on the entire length of the upper surface of the end portion, and the strip-shaped iron plate 3 is brought into contact with the convex curved surface 1b of the lath on the non-end portion.
Then, spot welding pieces 5a and 5b are formed, which are mutually opened and closed by the lath 2 and the strip-shaped iron plate 3 with the spot welding 4 as a fulcrum. In addition,
Reference numerals 6a and 6b denote outer opening guides provided at the outer ends of the pinching pieces 5a and 5b to facilitate pinching at the flange 7a of the H-shaped steel 7.

Reference numeral 8 denotes a V-shaped rib provided in the middle of the strip-shaped iron plate 3 to be fitted into the concave curved surface 1a. The V-shaped rib 8 strengthens the shape of the strip-shaped iron plate 3 and strengthens the strip-shaped iron plate 3 by its bending action.
The pinch stop spring action is reinforced and reinforced.

When a gap 10 is formed between the H-shaped steel 7 and the vertical wall 9 laid as beams, for example, in the construction process of a building or a building, the opposed-type sandwiching stopper pieces 5a provided at one end of the lath 2 are provided. The groove 5b is inserted into the flange 7a of the H-shaped steel 7 through the outwardly opening guides 6a and 6b, and is pinched and attached. The other end of the lath 2 is provided in the vertical wall 9 (not shown).
In a manner similar to that of inserting into the vertical wall 9 or abutting against the vertical wall 9 or folding against the vertical wall 9, the entire length of the gap 10 is closed and stretched in parallel with the plurality of laths 2 along the length of the gap. As a supporting surface for receiving each lath 2, for example, asbestos mud 11 is sprayed as a refractory base material, and the gap 10 is closed by painting.

When a part of the lath 2 is long in relation to the gap 10, the lath 2 is cut in the narrow direction along with the pinching pieces 5a and 5b to adjust the length. Since the pinching pieces 5a and 5b extend over the entire length, cutting at any place does not hinder the pinching action.

FIG. 3 shows a second embodiment, in which pinching pieces 5a and 5a are provided.
b, a lath 2 wave 1
The inner end of the strip-shaped iron plate 3a is spot-welded 4 to the relative surface of the lath 2 and attached to the lath 2. Reference numerals 6a and 6b denote outwardly opening guide portions. In this case, the V-shaped rib 8 is not provided.

FIG. 4 shows a third embodiment in which a wave 13 facing the wave 1 of the lath 2 is attached to a strip-shaped iron plate 3b forming one half of the pinching piece, and the convex curved surface 1 of the lath 2 facing the inner end.
The second embodiment is the same as the second embodiment except that it is mounted by spot welding 4 at b.

FIG. 5 shows a fourth embodiment in which an iron plate 15 having opposed-type sandwiching pieces 14a, 14b formed at an intermediate turn is spot-welded 16a to the entire length of one side end of the lath 2 at two points inside and outside. 16b shows an example.

[0014]

As described above, according to the present invention, a strip-shaped iron plate is attached so as to be cut along the entire length of one side end of the gap-forming lath, and a pinching stopper piece facing the lath is formed. As a result, one end of the lath can be directly pinched and attached to the flange portion of the H-shaped steel by the pinching piece, so that the on-site transportation of welding materials caused by the conventional welding and the use of skilled welding workers can be achieved. This eliminates the need for securing and dispatching, so that any person can easily and easily perform the mounting operation.

There is an effect that the length can be freely adjusted by cutting the lath together with the stopper piece.

Since the outer opening guide is provided at the outer end of the retaining piece, an effect is obtained that the retaining piece can be easily inserted into the flange portion of the H-shaped steel.

Since the V-shaped rib is provided in the middle of the strip-shaped iron plate forming the half pinch-stopping piece, the strip-shaped iron plate is strengthened to prevent deformation and to enhance the action of the pinch-spring during pinching. This produces the effect.
