Description

[Detailed description of the device]

[Industrial applications]

 The present invention relates to a lathe for tensioning a gap, and more particularly to a lath for tensioning a gap, which is provided with a clip at one end of the lath with a fixed interval for being clamped and fixed to a flange portion of H-shaped steel. .

[0002]

[Prior art]

 When a gap is created between the vertical wall and the H-shaped steel as a beam that horizontally bridges in the process of building a building or structure, one end of the lath is spot-welded to the flange of the H-shaped steel and is welded to the gap. A lath is stretched, and a fire-resistant base material such as rock wool is sprayed on or coated with the lath as a support to close it.

Since it is becoming more and more difficult to secure and dispatch a welding worker to weld a lath to H-shaped steel or the like at a construction site or a construction site, the applicant of the present application previously registered No. 3004874 utility model. Proposes that the flange of H-shaped steel is clipped and fixed by clips.

[0004]

[Problems to be solved by the device]

 However, in the registered model No. 3004874, the lath and the clip are separate, and a mounting piece is provided on one side wing of the clip, and the clip is entangled and attached to the mesh of the lath with the mounting piece. There were problems such as uneven mounting positions of clips, misalignment between the lath and clips, and clips falling off and lost.

[0005]

[Means for Solving the Problems]

 According to the present invention, a welding allowance is projected on the side surface of the bottom piece forming the clip, and a metal rod is sandwiched between the welding allowance and the lath for welding, so that one end of the lath is provided with a space. The problem is to fix such a problem by fixing a clip that is clamped and fixed to the flange of H-shaped steel.

[0006]

[Action]

 In the present invention, since the clip is fixedly attached to one end of the lath with a certain interval, one end of the lath is clamped and fixed to the flange portion of the H-shaped steel by the clip group, and the other end of the lath is fixed. It is inserted into the lateral groove provided on the vertical wall, abutted against the vertical wall, or bent and abutted in the gap.

【Example】

 Embodiments will be described below with reference to the drawings.

A lath 1 cut into a rectangular shape is provided with a wave 2 in which concave and convex curved surfaces alternate in the narrow direction, and a thin strip-shaped leaf spring material is bent in two to make a bottom piece 3 and an outwardly open guide. A clip 6 consisting of a pressing piece 5 with 4 is formed.

The clip 6 has a welding margin 3a protruding from the extension of the side surface of the bottom piece 3, and a metal rod 7 is sandwiched between the welding margin 3a and the lath 1 mentioned above to perform welding. Will be fixedly mounted with the opening 8 facing outward at a constant interval. The clip 6 has a smooth welding margin 3a extended and protruded from the side surface, so that it can be spot-welded with a spot welder without a problem in spite of being a three-dimensional shape. Moreover, the metal rod 7 is provided between the welding margin 3a and the lath 1. By sandwiching the metal rod 7, it is possible to prevent the corrugated deformation of the wave 2 attached to the lath 1 caused by the pressing work during the spot welding by the thickness of the metal rod 7. Reference numeral 9 is a bent portion of the clip 6 which is fixedly attached, and the clip is elastically opened and closed based on the bent portion 9 so that the clip has a pinching function. Further, 10a and 10b are extraction preventing claws formed by notches on both sides of the base of the outer guide 4.

The lath 1 is fixed to the flange portion 11a of the H-shaped steel 11 by sandwiching the clip 6 from the opening 8 and the other end of the lath 1 is inserted or projected into a lateral groove (not shown) of the vertical wall 12. It is pressed or bent and stretched in the gap 13, and a rock wool mud or the like is sprayed or painted on the lath 1 to a constant thickness to form a base material 14 to close the gap 13.

[0011]

[Effect of device]

 As described above, according to the present invention, since the welding margin is projected on the side surface of the bottom piece of the clip to be welded and mounted, the clip is securely fixedly mounted at a position spaced at one end of the lath. As a result, it is possible to prevent the displacement between the lath and the clip and the dropout or loss of the clip.

There is an effect that the lath can be clamped and fixed to the flange portion of the H-shaped steel without causing a displacement movement.

Since the welding margin of the clip is formed so as to project from the side surface of the bottom piece, there is an effect that the three-dimensional clip can be spot-welded to the lath without any trouble.

When the metal rod is sandwiched between the bottom piece of the clip and the lath for welding, there is an effect that it is possible to prevent the wave from being crushed and deformed due to the pressure during spot welding by the thickness of the metal rod.

Since the clip has an outer opening guide, it can be easily sandwiched in the flange portion of the H-shaped steel, and the clip has cut-out preventing claws formed at the notches on both sides of the base of the outer opening guide. If you fasten it with a pinch, it has the effect of not pulling it out.
