Description

[Detailed Description of the Invention] The present invention relates to a wall structure used for partition walls in buildings.

Conventionally, wall structures in buildings include: (1) A wall structure in which surface materials are attached to both sides of a base frame made of wood, lightweight steel, or a specially shaped metal frame.

(2) A wall structure in which composite panels are sequentially assembled upright, with a corrugated board made of asbestos slate, synthetic resin, etc. as the core material, and flat boards pasted together on both sides.

However, they all have the following drawbacks in terms of fire prevention and sound insulation performance.

In other words, in the case of (1), wood is combustible, and metal has disadvantages in terms of fire prevention, as its strength decreases when heated, and the base frame acts as a heat bridge to conduct heat.
Furthermore, since the joint joint of the surface material overlaps with the base frame part, this area tends to be a weak point in terms of fire prevention.Furthermore, although the base frame forms a hollow layer and has the effect of increasing sound insulation, the base frame itself produces noise. There is no blocking effect, and the base frame acts as an acoustic bridge, reducing the sound insulation performance.

In the case of (2), since the core material is corrugated, there is a drawback that gaps are likely to occur at the joints between the composite panels, which can cause problems in terms of fire prevention and sound insulation. There are structures that combine these, but these have the disadvantage of forming heat bridges and acoustic bridges, which have a negative effect on fire prevention and sound insulation performance.

In order to compensate for the above drawbacks, some measures have been taken to make the part a structure that combines other parts or a complicated shape.
All of these have drawbacks such as requiring other members and having a complicated structure.

This invention solves the above drawbacks, has excellent fire prevention and sound insulation performance,
Moreover, it provides a wall structure with a simple structure.

Conventionally, inorganic materials such as gypsum and concrete have tensile strength,
It has been technically difficult to make folded plates due to their low bending strength.

Recently, as a result of research on glass fiber reinforcement technology, we have developed glass fiber reinforced gypsum board (hereinafter referred to as GRC board) or cement board (hereinafter referred to as GRC board), which has high strength even though it is small in thickness.
It has also become possible to create a folded plate-like shape.

The present invention is intended to utilize the folded GRG board or GRC board obtained through this research and development as a building material.

Embodiments of the present invention will be described below with reference to the drawings regarding a partition wall using folded GRG plates.

First, the mounting hardware 3 is attached to the lower end of the upper slab 5 and the lower floor surface 6 at the location where the partition wall is to be provided.

The folded plate-like GRG 1 is formed into a continuous folded plate-like shape with a continuous slanted part 1c and IC' having different directions between the parallel plane parts 1a and lb, and whose cross-sectional shape is a regular truncated pyramid and an inverted truncated pyramid.

(See Figures 3 and 4) The folded GRG plates 1 are fitted and fixed into the upper and lower mounting hardware 3, and the folded GRC plates are sequentially
By abutting the sides in the width direction or partially overlapping the plates 1, the plates 1 are made adjacent to each other to form a continuous base structure.

A gypsum board as a surface material 2 is attached to this folded GRG board 1 using nails and a stable 4.

In this case, the joint joints 8 of the gypsum boards are folded plate GR
The partition is created by sequentially attaching gypsum boards to both the front and back sides of the base structure made of the folded GRG board 1 so that it is approximately in the center of the flat part 1aib of the convex surface that is not the joint part 7 of the G board 1 (Figure 3). The wall is constructed.

Although gypsum board is shown as an example of the surface material 2 to be used, other materials such as asbestos slate board and calcium silicate board can also be used, and when installing them, use nails, screws, stables, etc. that are compatible with each material. and attach it to a folded GRG plate or GRC plate.

(1) Folded GRG plate or GRC used in this invention
Since the board is an inorganic noncombustible material, if a noncombustible material is selected for the surface material, a wall with excellent fire resistance can be obtained.

(2) A truncated pyramid-shaped hollow layer is formed between the folded qRG board or GRC board and the surface material to improve fire prevention and sound insulation performance, but in addition, rock wool, glass wool, etc. By adding , its performance can be improved.

(3) The underlying structure of folded qRG plates or GRC plates acts as a continuous partition plate and provides considerable fire protection by itself.
In addition to having sound insulation performance, GRG boards or GRC boards have continuous sloped parts between parallel flat parts, and have a positive cross-sectional shape.
Since it is shaped like a continuous folded plate in the shape of an inverted truncated pyramid, the parallel plane parts 1a and lb of one continuous GRG plate or GRC plate are in contact with the surface plates 2 on both sides, and the contact area with the surface material 2 is There is a sufficient amount of wavy core material, which makes it easy to join with the surface plate, and together with the sloped portion 1c, it is possible to create a partition wall with greater rigidity than that of a corrugated core material.

(4) Joint joint 8 between surface materials and folded GRG plate or G
Since the joints 7 between the RC boards are not in the same location and the surface material supporting area is wide, even if there is a slight gap between the joints 8 between the surface materials, it cannot be a gap that penetrates the entire wall.
A wall with excellent fire prevention and sound insulation performance can be obtained.

(5) In order to prevent gaps, which are weaknesses in fire prevention and sound insulation, as in the past, use other members such as side plates and joint materials for the joint joint 8, or create a complicated structure such as a special shape. This has the advantage that it is unnecessary and the structure is simple.

(6) Furthermore, since the wall of the present invention has a structure in which the surface materials 2 on both the front and back surfaces are attached through a relatively thin base material and at positions that are not in the same cross section, it is possible to The effects of heat bridges and acoustic bridges, which are problems at the joints of frames and composite panels, are reduced, and the overall fire prevention and sound insulation performance is improved.

As described above, the present invention is a wall structure that is simple in structure and has excellent fire prevention and sound insulation performance.
