Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a building roof, floor,
The present invention relates to a mounting bracket used when a wall, a ceiling, etc., a sound insulation wall, a wall, etc. are made of a hollow extruded plate, and a mounting structure for mounting the hollow extruded plate using this mounting bracket, particularly in the wind. The present invention relates to a mounting metal fitting and a mounting structure capable of improving the strength of a mounting portion of a hollow extruded plate against external force such as load, seismic load, and load.

2. Description of the Related Art An example of a conventional mounting member for a hollow extruded plate and its mounting structure is shown in FIGS.
It will be described below with reference to (A) and (B). First,
The hollow extruded plate will be described with reference to FIGS. 8 and 9.
In (A), 1 is a generally used ceramic-based hollow extrusion-molded plate, in which a plurality of ribs 1c are provided between the front surface side wall portion 1a and the back surface side wall portion 1b. By this, a plurality of hollow portions 1d are formed inside.

When attaching the hollow extrusion molded plate 1 having the above-mentioned structure to a building frame or the like, FIGS.
As shown in (A) and (B), a flat steel mounting plate 3 having a female screw hole 2 at the center is inserted into the hollow portion 1d of the hollow extruded plate 1, and a mounting bolt 4 and a spring washer 5 are attached. , The washer 6, the Z-shaped metal piece 7, the through angle 8 and the like, and the beam 9 was attached and fixed. In addition, the hollow extruded molded plate was attached and fixed at a total of four positions, two at each of the upper and lower sides of the hollow extruded molded plate 1 when the long side is in the vertical direction.

[0004]

However, in the conventional mounting structure for the hollow extruded plate described above, the mounting plate 3 having the female screw hole 2 is brought into contact with the back surface side wall portion 1b of the hollow extruded plate 1. Since it is a structure that is fixed by attaching, when an external force such as a wind load, an earthquake load, and a load is applied, stress concentrates in the vicinity of the female screw hole 2 which is the central portion of the mounting plate 3, so that the load is low. However, there was a problem that the hollow extruded plate 1 was cracked and destroyed.

Particularly, when the mounting plate 3 is brought into contact with and fixed to the portion near the short side of the hollow extruded plate 1, this tendency becomes large and there is a problem that the strength is remarkably lowered. Further, in the above-mentioned conventional mounting structure, since the mounting strength is unstable and weak, it is necessary to mount and fix the hollow extruded molded plate 1 at the four positions of up, down, left and right when mounting it on the body side. There was also a problem that workability was extremely poor.

The fitting and mounting structure of the hollow extruded molded plate according to the present invention is a technique developed in view of the above-mentioned conventional problems, and particularly in the vicinity of both side ribs of the hollow part of the hollow extruded molded plate. The present invention provides a mounting metal fitting that can come into contact with the back surface side wall portion, and a technology of a completely new mounting structure configured to improve the strength of the mounting portion with respect to an external force using the mounting metal fitting.

[0007]

The metal fitting for a hollow extruded plate according to the present invention has a structure developed to fundamentally solve the above-mentioned conventional problems, and its gist is the roof. Installation fittings that can be inserted into the hollow part of a hollow extruded plate used for floors, walls, ceilings, etc. or sound insulation walls, walls, etc., and can attach the hollow extruded plates to the building frame, etc. This is a mounting member for a hollow extruded plate, characterized in that continuous or discontinuous convex portions are provided at the end portions of the sides, respectively, and a screw hole for a bolt is provided at substantially the central portion.

The hollow extruded plate mounting structure according to the present invention is a technique which is a fundamental improvement of the above-mentioned conventional mounting structure, and its gist is the roof, floor, wall, ceiling or sound insulation wall. In a mounting structure for mounting on a wall or the like, a mounting bracket having convex portions at the ends of two sides facing each other is inserted into the hollow portion of the hollow extruded plate, and convex portions on both sides of the mounting bracket are inserted. And a hollow extruded plate is attached to the hollow extruded plate by bringing the hollow extruded plate into contact with the back surface side wall portions near the ribs, respectively.

[0009]

The function of the mounting bracket for the hollow extruded plate according to the present invention is
As described above, since the continuous or discontinuous convex portions are provided at the ends of the two facing sides, when the fitting is inserted into the hollow portion of the hollow extruded plate, the ends of the two facing sides are inserted. It is possible to abut the respective convex portions in the vicinity of the rib portion of the corresponding hollow extruded plate.

As described above, in the mounting structure of the hollow extruded plate according to the present invention, the mounting metal fittings having the convex portions at the ends of the two opposite sides are inserted into the hollow portion of the hollow extruded plate. In addition, since the convex portions on both sides of the mounting member are configured to abut on the back surface side wall portions in the vicinity of the rib portion of the hollow extruded plate, stress is applied to the rib portions on both sides of the hollow extruded plate. It is possible to concentrate, whereby bending and shearing of the hollow part of the hollow extruded plate and tensile load of the rib part are generated, and the mounting strength can be remarkably improved.
