DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a building wall, floor,
The present invention relates to a ventilation board used for a roof or the like, and particularly to a ventilation board which also functions as a structural plywood or an external finishing material.

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. For example, 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 structure with respect to the frame. It is formed by hitting plywood.

[0004] At present, in houses and the like, dew condensation inside walls and roofs of buildings has been regarded as a problem. Therefore, conventionally, a ventilation layer is provided on a wall or the like by a ventilation layer method. For example, when a ventilation layer method is applied to a wall or the like of a building constructed by the above-described building frame construction method, the following method is employed.

That is, a Tyvek sheet is stuck on the outer surface of a structural plywood hit on a frame portion, and a body edge is vertically hit on the outer surface of the structural plywood. A siding or the like as an extending finishing material is struck, and a ventilation layer through which air can flow is provided between the body edge and the structural plywood.

[0006]

However, in such a ventilation layer construction method, it is necessary to prepare a body edge separately from the structural plywood, and to postpunch the body edge on the structural plywood. There was a problem that the material cost was increased, the labor was required, and the workability was poor .

The present invention has been made in view of such a conventional problem.
It eliminates the need for conventional rims and reduces material costs.
Reduction, labor and workability, and
Ventilation bow that can also function as plywood or external finish
The task is to provide a code.

I have.

FIG . 2 shows such a ventilation board 6 connected to a building wall.
The ventilation board 6 is attached to the nail 4
Hammered on the ground stud 5 on the wall
(See FIG. 5).

The reference numeral 11 denotes a rib 7 of the first board 6A.
Waterproof interposed at the joint between the second board 6B and the rib 9
It is paper.

FIG . 3 shows the application of the ventilation board 6 to the floor of a building.
The ventilation board 6 includes a nail (not shown).
To the beam 12 on the floor (see FIG. 5).
See).

FIG . 4 shows a state in which the ventilation board 6 is applied to the roof of a building. The ventilation board 6 is nailed to a tall tree 13 on the roof by a nail (not shown). In this case, the first board 6A has the plate surface on the side where the ribs 7 are formed facing outward and the ribs 7 extend in the vertical direction, the horizontal direction, or the oblique vertical direction, so that the base studs 5, beams 12,
It is arranged on the outer surface of the tall tree 13.

Further, the second board 6B is disposed on the outer surface of the first board 6A such that the plate surface on the side where the ribs 9 are formed faces the inner side and the ribs 9 extend in the vertical, horizontal, or oblique vertical direction. The two boards 6A and 6B are arranged on the outer surface of the frame portion and are driven. As a result, a ventilation layer is formed between the connecting surfaces of the boards 6A and 6B by the concave grooves 8 and 10 of the boards 6A and 6B.

The dimensions (mm) of each part of both boards 6A and 6B of the ventilation board 6 are as follows, for example. Board width is 9
10, the plate length is 2440, the plate thickness is 12, the width of the ribs 7 and 9 is 20 at both ends, 40 at the portion between both ends,
The height of the ribs 7, 9 is 10. According to such a configuration,
By simply hitting the ventilation board 6 on a frame formed by walls, floors, and roofs of a building, a ventilation layer equivalent to the ventilation layer in the conventional method can be easily formed, and the conventional ventilation rim can be formed. It is not necessary to prepare the rim separately from the structural plywood as in the ventilation layer construction method using the plywood, and there is no need to post-punch the rim on the structural plywood. Workability can be improved.

Especially when applied to the floor , the ventilation board
Since the ribs 7 and 9 in FIG. 6 function as joists, they can also be used as boards (structural plywood) that receive a vertical load from above . In the ventilation board 6, the rib 9 forming portion is substantially I-shaped. In the case of a floor, the floor can be omitted, and the floor can be used as a structural plywood as described above.

Further, in the ventilation board 6 , the second board 6B becomes a finishing material on the wall as it is, and
The groove portions 8 of the first board 6A and the second board 6B,
By setting 10, the width of the ventilation layer can be increased. The number of the ribs 7, 9 and the dimensions (width, height, pitch) and shape of each part are set as described above, but are not limited thereto, and may be freely selected according to the required form of the ventilation layer. be able to.

[0023]

As described above , according to the first aspect of the present invention, it is possible to easily form a ventilation layer on a wall, a floor, or a roof of a building, and to use a ventilation layer method using a rim or the like. ,
It can reduce material costs, reduce labor, and improve workability, and when applied to the floor, the ribs of the ventilation board function as joists, so boards that receive vertical loads from above ( Can also be used as structural plywood)
The strength is increased by the rib forming portion, and in the case of a floor, the floor joist can be omitted, and the floor can be made to have a rigid structure without the necessity of a fire beam.

In particular, the wall has an advantage that it can be used as a finishing material as it is, and that the width of the ventilation layer can be increased by the concave grooves of the first board and the second board.
