Abstract

PURPOSE: To facilitate the fitting work to a wide-flange shape steel, by providing mutually facing clipping pieces holding the flanges of the wide-flange shape steel, at the full length of one side end of a lath. CONSTITUTION: A belt-form iron plate 3 is placed on the full length of the upper face of one side end in the longitudinal side of a breakable lath 2 having a rectangular shape with a narrow width and also having waves 1 that recessing curved faces and protruding curved faces are formed alternately, and the iron plate 3 is fixed to the lath with spot-welding 4 at the contact points with the protruding curved faces in the middle side of the lath and mutually facing clipping pieces 5a, 5b are formed so as to mutually open or close the clearance by the lath 2 and the iron plate 3 with the welded part 4 as the supporting point. When a clearance is brought about between the wide-flange shape steel 7 laid as a beam and the vertical wall 9 for instance, the clipping pieces 5a, 5b are pushed into the flange 7a of the wide-flange shape steel 7 by means of the guides 6a, 6b opened outward to clip the flange and fix the lath. The other side end of the lath 2 is inserted in the groove provided on the vertical wall 9 and the clearance 10 is shutt by parallelly arranged and extended laths 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lath for tensioning a gap, and more specifically, when a large or small gap is generated between an H-shaped steel and a vertical wall in the process of building a building or a structure, the gap is made of rock wool. The present invention relates to a lath that is stretched as a support for the base material in order to close it by spraying or coating the fire resistant base material.

2. Description of the Related Art As a technique of this kind, there is Japanese Utility Model Laid-Open No. 6-4237 filed by the applicant of the present application. In this publication, wavy lines in which protruding strips alternate are formed on both sides of a lath having a braided shape of thin metal wires, and an annealed iron wire having a thickness that enables welding is orthogonal to the protruding strips on one surface of the lath. It describes a lath for tensioning a gap, which is characterized in that a plurality of laths are placed side by side.

[0003]

However, according to the publication, one end of the lath is welded and attached to the flange portion of the H-shaped steel by using an annealed iron wire and stretched. However, there is a problem that it is necessary to secure and dispatch a worker skilled in welding technology, and there is a problem that it is not easy to stretch the lath.

[0004]

SUMMARY OF THE INVENTION According to the present invention, an opposed type clip member capable of cutting and adjusting the lath and a metal plate or a metal plate alone is formed on the entire length of one side end of the lath to form an H-shaped steel. The problem is solved by sandwiching and fixing it on the flange portion.

[0005]

According to the present invention, one end of the lath is clamped and fixed to the flange portion of the H-shaped steel with facing clamp members, and the other end of the lath is inserted into a groove provided in a vertical wall or folded into the vertical wall. The lath is stretched in the gap formed between the H-shaped steel and the vertical wall by hitting or abutting. In addition,
If the lath is long due to the gap, the length can be adjusted by cutting the lath together with the sandwiching piece.

[0006]

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

FIGS. 1 and 2 show a first embodiment, which is one side of the long side of a severable lath 2 having a narrow rectangular shape and a wave 1 having concave curved surfaces 1a and convex curved surfaces 1b alternating 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 in contact with the convex curved surface 1b of the lath on the non-end side.
Spot welding 4 is attached to the plate, and the opposed pinching stoppers 5a and 5b which are opened and closed by the lath 2 and the strip-shaped iron plate 3 are formed with the spot welding 4 as a fulcrum. In addition,
Reference numerals 6a and 6b denote outer opening guide portions provided on the outer end portions of the pinching pieces 5a and 5b for facilitating pinching on the flange 7a portion of the H-shaped steel 7.

Numeral 8 is a V-shaped rib provided in the middle of the band-shaped iron plate 3, which is fitted in the concave curved surface 1a, and the V-shaped rib 8 strengthens the shape of the band-shaped iron plate 3 and bends the band-shaped iron plate 3.
The pinch prevention spring action of is reinforced and strengthened.

In the process of building a building or structure, for example, when a gap 10 is formed between the H-shaped steel 7 and a vertical wall 9 which are laid horizontally as a beam, a facing-type clip 5a provided at one end of the lath 2, 5b to the flange 7a of H-shaped steel 7
Open from 6a, 6b and fix by pinching, insert the other end of the lath 2 into the groove (not shown) provided in the vertical wall 9,
Or, by abutting against the vertical wall 9 or folding it against the vertical wall 9, a plurality of laths 2 are arranged side by side to close and extend the gap 10 to support each lath 2 as a supporting surface and as a refractory base material. For example, rock wool mud 11 is sprayed and painted to close the gap 10.

Due to the relationship with the gap 10, when the lath 2 is partly long, the length of the lath 2 is adjusted by cutting the lath 2 together with the sandwiching pieces 5a and 5b in the narrow direction. Since the clip-stopping pieces 5a and 5b extend over the entire length, the clip-stopping action will not be disturbed no matter where they are cut.

FIG. 3 shows a second embodiment, in which the band-shaped iron plate 3a forming one half of the sandwiching pieces 5a, 5b is provided with a wave 12 for fitting with the wave 1 of the lath 2, and at the inner end of the band-shaped iron plate 3a. The lath 2 is spot-welded 4, and the other structure and operation are the same as in the first embodiment.

FIG. 4 shows a third embodiment, in which the lath 2 is attached to the strip-shaped iron plate 3b.
This is the same as the first and second embodiments except that a wave 13 facing the wave 1 is added.

FIG. 5 shows a fourth embodiment of the present invention, in which an iron plate 15 having facing holding members 14a, 14b formed on the entire length of one longitudinal end of the lath 2 is spot-welded 16a, 16b at two points. Is shown. Other configurations and operations are the same as those in the first embodiment.

[0014]

As described above, according to the present invention, since the facing type pinching piece which opens and closes with the spot welding portion as the fulcrum is formed so that it can be cut to the entire length of one end of the lath for tensioning the gap, One end of the lath can be attached to the flange of the H-shaped steel not by welding but simply by sandwiching it, eliminating the need for on-site transportation of welding materials and the securing and dispatching of skilled welding workers, which was caused by welding attachment. As a result, any person can easily and easily carry out the mounting work.

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

Since the outer opening guide is provided at the outer end of the pinch-preventing piece, there is an effect that the pinch-preventing piece can be easily pinched in the flange portion of the H-shaped steel.

Since the metal plate is provided with a folded bend or a V-shaped rib or a wave of a fitting type, a facing type or the like for forming the pinch-preventing piece, the metal plate is reinforced to prevent deformation and the pinch-preventing piece The effect of being able to reinforce and strengthen the pinching spring action is produced.
