間に浸入した雨水等の水滴の侵入口とならない。The closed state of the closed wall of the wall partitioned by the structural plywood, the frame material and the gypsum board is released by the ventilation hole, and the air in the closed room flows through the ventilation hole. In particular, in the space between the structural plywood and the outer wall material generated by the interposition of the rim (the rim space), the air warmed on the ground during the day enters as an ascending airflow, so that the ascending airflow is directed downward. When the outside air temperature drops due to the introduction into the closed room in the structural plywood and the outside air temperature drops, the closed room air flows into the rim space due to the difference between the air inside the closed room and the outside air temperature, and the outside air frequently enters and exits the closed room. Is performed, the action of evacuating moisture from the closed room is promoted, and moisture is not formed in the closed room, thereby preventing the accompanying corrosion. Furthermore, since the eaves are provided so as to cover the entire upper part of the outside of the cylindrical ventilation part, the ventilation holes for removing moisture are formed by dew condensation flowing down the outer surface of the plywood and rainwater entering the trunk space. It does not become an entrance for water droplets such as.

る。In the two-by-four construction method, a wall frame is formed by connecting a plurality of vertical frame members 2 between edge frame members 1 (lower frame member and upper frame member) to form a frame, and a structural plywood 3 is mounted on the frame. This wall frame is built on a floor frame 4 so that the plywood 3 is on the outside, and a heat insulating material 5 such as glass wool is provided between the frame materials 1.
The gypsum board 6 is stretched on the inner surface, and the outer wall material 8 is stretched on the outside of the wall frame via the rim 7 to form the outer wall surface of the two-by-four construction house. Is a method in which a ventilation hole is previously formed in the structural plywood 3 and an appropriate ventilation fitting is attached to the ventilation hole. The vent fitting A has a flange portion b formed at the base end side of the vent portion a closely fitted to the perforated vent hole, the distal end portion of the vent portion a is an eave-shaped portion c, and the eave-shaped portion c An insect net d is stretched in the lower ventilation hole, and is attached to the ventilation hole of the structural plywood 3 in advance.

In addition, if the ventilation hole fitting itself has sufficient strength, the structural strength that is reduced by forming the ventilation hole in the plywood can be sufficiently supplemented.

At least one space may be provided in the space surrounded by 2, but if a plurality of spaces are provided, the flow of air in the space is improved, and the effect is doubled.

As shown in FIGS. 4 and 5, a flange b1 is provided around the eaves c1 and a screw is formed on the outer peripheral surface of the vent hole a1. And an arbitrary structure can be selected such that the inner flange b2 is screwed onto the screw and attached to the structural plywood 3, or the insect net d may be formed inside.

When forming the wall surface of a house by the construction method , a ventilation hole is previously formed in the structural plywood, and
Attach a ventilation part having a hole and an eaves-shaped part to the ventilation hole
The simple means of adding the above means, to release the sealing of the inside space of the structural plywood, which was conventionally sealed , to realize effective ventilation between the inside of the sealed space and the outside air, because of the moisture in the space This prevents corrosion of steel.
