DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a ventilation layer in a building, and more particularly, to a structure of a ventilation layer formed between a structural plywood such as plywood and a finishing material such as siding which is struck thereon. .

[0002]

2. Description of the Related Art In recent years, by building a framework by connecting building members using a joint device, the connection of building members can be completed only by a simple operation of using fastening means such as simple bolting. A technique has been proposed in which various types of houses can be successively constructed according to a demand of a consumer using a small number of standard products, as if combining block toys of various shapes.

[0003] For example, Japanese Patent Publication No. Hei 6-57973 discloses that a frame of a building is constructed by connecting a building member such as a pillar, a base or a beam using a fastening means such as a bolt and a joint device for a building member. A framework construction method of a building to be constructed is disclosed. A wall of a building constructed by such a method of constructing a framework of a building is constructed by fitting a framework into a frame formed by pillars, a base, a body difference, and the like, and forming a structural plywood with respect to the frame. And formed.

[0004] Conventionally, the following method has been adopted when a ventilation layer method is applied to a wall as described above. That is, waterproof paper is stuck on the outer surface of the structural plywood that has been punched into the frame portion, and the trunk edge is vertically struck on the outer surface of the structural plywood, and further parallel to the structural plywood on the outer side of the trunk edge. A siding or the like as a finishing material extending to the rim, and a ventilation layer through which air can flow is provided between the body edge and the structural plywood.

[0005]

However, in such a conventional ventilation layer construction method using a ventilation rim,
Since it is necessary to prepare a rim separately from the structural plywood and post-punch the rim to the structural plywood, there is a problem in that material costs are increased, labor is required, and workability is poor.

As a technique for solving such a conventional problem, a plurality of rows of ribs projecting from a surface of a structural plywood and extending in a predetermined direction are provided on one surface of the plywood at predetermined intervals.
A groove is formed between the adjacent ribs and extends in the same direction as the direction in which the ribs extend. On the other hand, air flows between the groove and the inner surface of the finishing material that is struck on the plate surface opposite to the plate surface struck against the frame portion. There has been proposed a structure of a ventilation layer in a building in which a space serving as a ventilation layer is formed.

However, such a conventional technique has the following problems. That is, when combining plywood and plywood adjacent in the horizontal direction, and plywood adjacent in the vertical direction, there is no guide in the combination of both plywoods, so it is difficult to accurately align and combine both plywoods, There was a problem that plywood was inferior in assembly workability.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and in the case where a ventilation layer is formed by using a structural plywood and a finishing material, the assembling workability of the structural plywood is improved. The task is to improve

A space is formed between the inner surface of the siding as the finishing material to be hammered and the groove to serve as a ventilation layer through which air flows.

[0012] The above structure will be described in detail in FIG.
The plywood 11 is formed in a rectangular shape in which both sides facing each other are long, and both sides facing each other are short. A large number of ribs 12 protruding from the plate surface are arranged at predetermined intervals on the plate surface opposite to the plate surface that is pressed against the frame formed by the building member in the wall of the building of the plywood 11. A groove 13 extending in the same direction as the direction in which the ribs 12 extend is formed between the ribs 12 to be formed.

The ribs 12 may be formed integrally with the plywood 11 or may be provided with a separate member fixed thereto. The ribs 12 are formed in the same rectangular cross section with the same width from the base to the tip. In this case, the width of the base is equal to the width of the tip. The rib 12
May be formed in a trapezoidal cross section such that the width gradually decreases from the base toward the tip.
