Description

[Detailed description of the invention] The present invention relates to a wall board mounting structure in which lightweight aerated concrete (hereinafter abbreviated as ALC board) is attached to a building frame as a wall board. A wall board characterized by penetrating the heads of nails into the wall board to a predetermined depth when fixing the wall board, and filling holes in the wall board surface caused by this penetration with an elastic filler. This relates to the mounting structure.

Conventionally, as shown in Fig. 1, the method for attaching ALC board wall panels to a building frame is as follows: ALC board 1 is brought into contact with the outer surface of building frame 2 such as a stud, rim, pillar, etc., and then a nail or screw is attached. Type 3 is driven into a predetermined position of this frame 2, its head is penetrated to a predetermined depth, and the hole 4 created by the penetration of this head is filled with a special mortar having the same appearance and water absorption properties as the ALC board. Filling material 5 is filled, and an interior material 6 such as a gypsum board is attached to the indoor side of the frame 2 by driving nails 7. There are many accidents in which the filler 5 filled in the hole 4 falls off due to shock and vibration during nailing, and for this reason, it is necessary to refill the filler again before the exterior finishing work. There were some drawbacks.

Furthermore, since the external wall materials, interior materials, and exterior finishing are generally carried out by different contractors, and the construction dates are also different, redoing the filling process becomes a troublesome problem.

The mounting structure according to the present invention is a completely new technology developed in view of the drawbacks of the conventional art.

An embodiment of the structure according to the present invention will be described with reference to the drawings. In Fig. 2, the ALC board 1 is brought into contact with the outer surface of the building frame 2, and nails 3 are driven into the ALC board 1. The hole 4 formed by fixing it to the nail 3 and penetrating the head of the nail 3 is filled with a filler 5' made of a urethane sealant mixed with fine powder of ALC board at a weight ratio of 15%. The hole 4 is completely buried, then the interior material 6 made of gypsum board is nailed in place from the opposite side of the frame 2 with nails 7, and an acrylic sand wall-like spray material is applied to the outer surface of the ALC board 1. Then, the outer device 8 is formed and the whole is constructed.

The filling 5' used in the present invention may be any material as long as it has elasticity, and is not particularly limited, but it is preferably a sealant, putty, or caulking material commonly used in buildings mixed with an inorganic filler. In particular, the above-mentioned urethane sealant is suitable because it takes a long time to cure and is highly elastic.

A comparison of the case where a conventional special mortar is used as a filling material and the case where the elastic sealant of the present invention is used as a filling material shows that the conventional method has less impact and vibration when removing nails from interior materials. In contrast, 25 to 30% of the particles fell off due to the structure of the present invention, whereas such a phenomenon of falling off was not observed at all in the structure of the present application.

As mentioned above, in the wall mounting structure according to the present invention, the hole penetrated by the head of the nail is filled with an elastic filler, so it will not be damaged by shocks, vibrations, etc. when nailing interior materials etc. There is no fear that the filling will fall off, and since the filling contains an inorganic filler, there is no need to worry about color unevenness in this area even when the exterior is finished, resulting in a beautiful and attractive appearance. It has the characteristic that a solid structure can be easily obtained.
