[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall basement structure and a wall basement assembling method which have high heat insulation and can be efficiently constructed.

[0002]

2. Description of the Related Art According to the Building Standards Law, load-bearing wall materials are not recognized as load-bearing walls unless they are directly fixed to structural members such as columns with nails. Therefore, conventionally, the heat-insulating material (5
In the case of constructing the wall foundation structure using the heat insulating composite plate (51) in which 3) are laminated, as shown in FIG. 22, a portion which comes into contact with the structural material (10) and is nailed and fixed (a portion to be nailed (55 )), The heat insulating material (53) is adhered, and as shown in FIG.
The portion (55) where the heat insulating material (53) is not laminated in (1) is abutted from the inside so that the structural material (10) is fitted, and nailed and fixed with the nail (31) as shown in FIG. I was going by.

In this case, in order to manufacture the heat insulating composite plate (51), as shown in FIG. 22, the heat insulating material (53) is cut in advance in accordance with the shape of the main body, and the load bearing wall material (52) is cut. Scheduled nailing (5
5) Attaching the adhesive to the predetermined position P with an adhesive, avoiding 5), applying the adhesive only to the predetermined position P, bonding the heat insulating material (53), and determining the nailing expected portion (55), the knife The heat insulating material (53) of the nailing-scheduled portion (55) was cut off by heating or raising and lowering the heat ray.

[0004]

In the case of the above-mentioned conventional wall base structure, the nailing-scheduled portion (55) is fitted to the structural material (10) from the inside, and can be easily constructed. The portion of the structural material (10) shown in (1) is made of wood, and has a problem that the heat insulating effect is lower than that of the heat insulating material (53) and the heat insulating effect of the entire wall is reduced.

In the conventional method for manufacturing a heat insulating composite plate (51), first, the heat insulating material (53) is trimmed to a predetermined size in accordance with dimensions such as a column height and an opening. As shown in FIG. 26, it is necessary to apply a jig (54) for positioning in order to avoid the nailing portion (55) of (52) and bond it, and there is a problem that it takes a lot of trouble and time. Also, in a method of applying an adhesive only to the predetermined position P and attaching the heat insulating material (53), and then cutting off the heat insulating material (53) of the nailing scheduled portion (55), the adhesive is also applied. Positioning of the part is required, which rather increases labor and time.

Further, for example, when the heat insulating material (53) having a length exceeding 3000 mm is to be cut by a hot wire, the thermal expansion of the hot wire becomes large, and the bending of the heat insulating material (53) at the central portion is caused by the pressure of the heat insulating material (53) at the time of cutting. However, there is also a problem that the machining accuracy is deteriorated due to the increase in size. In particular, when it is necessary to increase the number of studs or the like in order to enhance the earthquake resistance, as in a conventional wooden house, the above-described problem is increased, and it has been difficult to achieve both the earthquake resistance and the heat insulation. Further, in such a wooden house, standardization is difficult, and the sizes and types of the heat insulating composite boards are abundant, so that it is difficult to efficiently manufacture the heat insulating composite boards and the workability is deteriorated.

According to the wall basement structure and the wall basement assembling method of the present invention, the heat insulating composite plate (1) is made of a heat insulating material (3) as shown in FIG.
The structural member (10) does not fit into the nailing-scheduled portion (5) because the member is in contact with the structural member (10) from outside.
