Abstract

PROBLEM TO BE SOLVED: To improve the durability of structural materials by preventing dew condensation from generating in a wall body inside and a mortar layer from warping by the external pressure in the external wall by a mortar finish wet method in a wooden house. SOLUTION: An external wall structure provided with a plate material 2 set to an outside face of a structural material 1 such as a sill, a beam, and a column which are the external wall substrates and formed into a mortal layer 9 in the outside face of the plate material 2 via waterproofing paper 7 and lath 8 has such a structure as having an air ventilating path in the wall body by interposing an angle ventilating substrate between the plate material 2 and the mortar layer 9. The ventilating substrate 6 forming the ventilating path has a structure bent into a bellows so as to be conveniently held and attached.

2. Description of the Related Art Conventionally, the outer wall of a mortar-painted wet construction method for a wooden house is provided with a lath base plate on the outer surface of a structural material such as a foundation, a beam, a pillar, etc., which is a base of the outer wall, and waterproof on the outer surface of the lath base plate. It has a structure in which a mortar layer is formed via paper and a lath net.

However, in the construction method using a plate material such as a plywood for a structure, four circumferences of an outer wall are surrounded by structural materials such as a base, a beam, a pillar and a stud, and the surface has no gap. Since the plate material is stretched, it is almost in a sealed state, and when the moisture of the outside air enters through the mortar layer and dew condensation occurs in the wall, the dew condensation water is not discharged. However, there is a problem that the plate material is corroded with time and the durability is reduced.

For this purpose, a rim is provided vertically on the outer surface of a plate material such as a structural plywood, a waterproof paper is stretched on the outer surface of the rim, and a lath net is attached on the outer surface to form a mortar layer. That construction method is also being carried out.

However, in this method, since a space is formed between the vertical torso edges, ventilation can be taken through the space, moisture in the wall can be released to the outside, and the problem of dew condensation can be solved. Therefore, when an external pressure is applied to the outer surface of the mortar layer, the mortar layer is warped and causes cracks.
