The wall structure 5 on the other side has a symmetrical structure in which upper and lower lining plates 6 and 7 are similarly integrated by a calcium silicate plate with an adhesive or the like, and is attached via studs 8 and screws 9. It has a dry structure with the fire resistance required by law.

Showa 56's (see FIG. 7) As shown in FIG. 7, a partition wall 12 developed in this period is provided with glass fiber-filled gypsum board for both the upper and lower siding plates 13 and 14, and includes studs 8 and screws 9. Both wall components 2 and 5 are configured to have a bilaterally symmetric structure via the, and are characterized by an inexpensive dry structure wall.

1986 (see FIG. 8) The partition wall 17 developed in this period is, as shown in FIG. 8, the upper plate 18 of the wall structure 2 on one side is a gypsum board,

[0009] For example, a room with water or humid water around, such as a kitchen, a kitchen, or a toilet, on one side through a partition wall,
On the other side, there are many examples of construction in which a room such as an office room that does not need to consider water supply is adjacent to each other, and there is a demand for the development of a partition wall having performance according to the purpose of each room.

On the other hand, the partition walls 1, 12, ...
Is a bilaterally symmetric structure, and in order to solve the problem of water circulation, considering the economical efficiency, the partition wall 23
However, even in a room where water circulation is not considered, since the partition wall 23 has a bilaterally symmetrical structure, the calcium silicate plate surface of the upper plate 26 is exposed,
When the finishing is performed, a sealing treatment is required, resulting in a relatively expensive finish, and there is a problem in economical efficiency. Further, in addition to the problem of water surroundings, as measures against the sound insulation caused by the flow of water, the subbing plates 25 and 27, the gypsum board 12,
The gap 28 between the 12 is filled with a sound insulating material having a high sound insulating property, such as rock wool felt, to perform processing such as enhancing the sound insulating performance.

The inventors of the present application have proposed the above-mentioned conventional partition wall 1,
12 and so on have a symmetrical structure via the studs 8, and as a result of various research and development of partition walls considering water circulation measures, as a result, from the technical idea of the conventional symmetrical structure. This is a partition wall that was developed with a concept changed to a left-right asymmetric structure.

The present invention focuses on the water resistance, moisture resistance, and impact resistance of the calcium silicate plate as described above, and the calcium silicate plate is the upper plate of the wall structure on one side and the lower plate is the lower plate. However, it is intended to be a partition wall according to the purpose of use in each room by integrating it with a different material different from this and forming the wall structure on the other side via the stud in a left-right asymmetrical structure.

The upper plate of the structure is a calcium silicate plate, the lower plate is composed of a different material from this, and the wall structure on the other side is asymmetrically structured with the wall structure on the one side through the stud. It is characterized by that.

Further, in the present invention, the underlaying plate of the wall structure on one side may be made of gypsum board, slag / gypsum board or fiber-mixed gypsum board.

[0014]

According to the present invention, the calcium silicate board surface of the upholstery board constituting the wall construction of the left-right asymmetric structure is arranged in a room such as a kitchen or a kitchen where there is water or humid surroundings. Therefore, it has excellent water resistance and moisture resistance, and can sufficiently cope with impact resistance. Also, by arranging the gypsum board surface of the upholstery board on the other side in an adjacent room that does not consider the water circulation, it is possible to meet the purpose of each room.

Further, the present invention is a wall structure having a left-right asymmetric structure, has a low resonance transmission, and has excellent sound insulation performance.

It was found that the bending strength was maintained and the bending strength was reduced by 88 to 83%. It was also confirmed that the fiber-containing calcium silicate board can be used around water, because the strength retention during moisture absorption is larger than that of gypsum board and the original strength is obtained when dried.

Regarding mold resistance, JIS Z 291
In the test based on 1 (wet method), since the fiber-containing calcium silicate plate is alkaline with PH10, no mold was found even if bacteria were attached to the surface. .

In the test for impact strength, the value of grade 7 could be confirmed when the impact value was 15 kg · m. The grade of this impact force is stipulated in "Research on material design" prepared by the Institute of Architecture, Ministry of Construction.
