Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an outer wall structure of a building or a structure. More specifically, a ventilation path is formed between the wall base consisting of main columns and studs and the wall body, and at the base part, a ventilation tree is formed so as to communicate with the outside air. The present invention relates to an outer wall structure which is constructed so that it can be constructed at low cost and in a short period of time for the purpose of removing the corrosion of the steel, prolonging its life by suppressing corrosion, and improving the appearance.

[Conventional technology]

In the conventional outer wall structure of a general wooden house, as shown in FIG. 6 (a), a tree 4 is horizontally placed on a base 1 of a wall foundation 3 composed of a base 1, girders 2 and pillars (studs). There is one in which a wall material 6 such as siding is directly arranged on the wall foundation 3 after the water drainer 5 having a deformed Z-shaped cross section is fixed so as to cover the batten 4. In addition, 7 is a foundation, 8 is an eaves roof board, 9 is a field board, and 10 is a nose cover board. In addition, a heat insulating material 11 made of glass wool or the like (partly omitted) is filled in the internal space of the wall formed by the base 1 of the wall base 3, the girder 2, and each pillar (stud). According to this outer wall structure,
Since the wall base material 3 and the wall material 6 are in close contact with each other, the moisture that has permeated from the room is not discharged and is stored inside the wall body, and dew condensation occurs due to a decrease or increase in the outside temperature.
No. 11 has become a "nure rag", which causes a decrease in heat insulation and also has a drawback that the durability of the wall is deteriorated. For this reason, as shown in FIG. 6 (b), for example, a vertical furring strip is arranged on the wall foundation 3 to form a gap 12 between the wall foundation 3 and the wall material 6,
A structure utilizing 12 as a ventilation path is gradually being constructed. However, since the foundation 7 usually projects outward from the base 1, the opening of the lower portion of the void 12 is insufficient, and there is a disadvantage that the function as a ventilation path cannot be fully utilized. In addition, when the outer surface of the foundation 7 is coated with lath material or mortar, there is a drawback that the lower opening of the void 12 is closed.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention fixes a mounting body composed of a vertical furring strip or a horizontal furring strip on a wall foundation so as to form a continuous void (ventilation passage) from the base toward the girder, A cross-section deformation Z is provided in the batten to be fixed to the base part, in which a vent hole formed of a plurality of through holes is provided to connect the vent passage formed by the mounting body to the vent hole and to cover the batten.
The present invention proposes an outer wall structure in which a space is formed between a V-shaped decorative surface and a surface in which a ventilation hole is formed and a ventilation path in the wall body can be reliably and sufficiently utilized. .
