It is designed to be fixed with nails or metal fittings.

[0003]

In the conventional ventilation method described above, the vertical furring strip 14 that sandwiches the moisture-permeable waterproof sheet 13 forms a ventilation layer (gap) between the back surface of the outer wall plate and the moisture-permeable waterproof sheet 13. Plays the role of a spacer. Therefore, in the conventional ventilation method, many vertical furring strips 14 are required to form the ventilation layer, which not only increases the amount of wood used, but also the troublesome nailing of the vertical furring strips 14 to the columns 11 and the studs 12. There is a drawback that work must be performed and workability is poor.

Conventionally, as a simple construction method which does not use a vertical furring strip, there is also a direct-adhesion construction method in which an outer wall board is directly struck by sandwiching a moisture-permeable waterproof sheet between columns and studs. A gap (ventilation layer) cannot be provided between the back surface and the moisture permeable waterproof sheet, and the moisture permeable waterproof sheet will be in close contact with the back surface of the outer wall plate, so the back surface of the outer wall plate due to the temperature difference between the inside and outside air. It is impossible to prevent dew condensation on the

The present invention has been made in consideration of such circumstances, and an object thereof is to ensure the air permeability on the back side of the outer wall plate while satisfying the requirements of workability, cost efficiency and reduction of the amount of wood used. Another object of the present invention is to provide a structure for directly attaching an outer wall plate that can prevent condensation on the back surface of the outer wall plate.

[0006]

In order to achieve the above object, in the structure for directly adhering an outer wall plate according to claim 1 of the present invention, a moisture permeable waterproof sheet is sandwiched on the back side of the outer wall plate directly adhered to a pillar material. In such a structure, the moisture permeable waterproof sheet can be obtained by fitting and mounting an elastic clamp having a lateral cross section of Ω shape or inverted U shape on the outer side portion of the column member from above the moisture permeable waterproof sheet. Is sandwiched between the column members on the outer side, and a ventilation layer is formed between the moisture-permeable waterproof sheet and the back surface of the outer wall plate.

In this case, as in claim 2, the draining member interposed between the lower end portion of the outer wall plate and the base is provided with a receiving portion for receiving the lower end surface of the outer wall plate. A configuration may be used in which a ventilation portion that communicates with the ventilation layer on the back surface side of the outer wall plate is formed. Further, as in claim 3, the draining member may be provided with a ventilation band that also serves as a spacer and is in contact with the back surface of the outer wall plate so as to communicate with the ventilation layer.

[0008]

According to the above-mentioned direct-bonding structure of claim 1, when the outer wall plate is directly bonded, the elastic clamp having a cross section of Ω shape or inverted U shape is applied to the pillar material from above the moisture-permeable waterproof sheet. Fit it on the outer side of. In this state, the elastic gripping tool is engaged and held with the moisture permeable waterproof sheet being sandwiched by the elastic force of itself on the outer side of the column member, and the moisture permeable waterproof sheet is only the fitting amount of the elastic clamping tool. It will be pushed to the inside (inside the room). After that, if the outer wall plate is directed to the elastic holding tool and directly attached to the column member with nails, screws, mounting brackets, etc., the work of attaching the outer wall plate is completed. In this direct attachment structure, the moisture permeable waterproof sheet is pushed inward by the amount of the fitting amount of the elastic clamp, so that the ventilation layer (gap) is formed between the moisture permeable waterproof sheet and the back surface of the outer wall plate. Are formed, and the flow of air through the ventilation layer prevents dew condensation on the back surface of the outer wall plate.

Further, according to the second aspect, a draining member is interposed between the lower end portion of the outer wall plate and the base, and the lower end surface of the outer wall plate is supported by the receiving portion provided on the draining member. Since the receiving portion is provided with the ventilation portion, outside air enters the ventilation layer on the back surface side of the outer wall plate through the ventilation portion.

Further, in the third aspect, the ventilation band provided also on the draining member and also serving as the spacer is in contact with the back surface of the outer wall plate. Thus, the ventilation band reinforces the lower end portion of the outer wall plate from the back side, and at the same time, ensures the air permeability to the ventilation layer on the back side of the outer wall plate.
