2. Description of the Related Art A housing structure by a ventilation method in which a ventilation space is provided between a heat insulating material and an outer wall material to flow air is used.

[0003] In such a ventilation method, the space between the heat insulating material and the outer wall material is usually secured by a base material such as a vertical waist edge or a horizontal waist edge for attaching the outer wall material outside the heat insulating material. A ventilation space is formed between a plurality of body edges arranged in parallel. In such a ventilation space, it is necessary for the air to flow in the vertical or horizontal direction over the entire wall surface. If the air is blocked halfway by a frame material of an opening provided in the wall surface, the air stays and the ventilation method is used. Effect is significantly impaired.

FIG. 7 is an external view of a wall including a window of a general ventilation type house. The outer wall 1 has a sash 6 attached to four edges of a rectangular opening 5 surrounded by a pillar 2 made of wood on the building frame side, a gate (upper frame material) 3 and a window sill (lower frame material) 4. A frame is formed, and a window member 7 (shoji) made of, for example, double-glazing is fitted therein. A wall panel made of a heat insulating material (not shown) is attached to the skeleton side, and a plurality of horizontal trunks 8 are provided outside the heat insulating material via waterproof paper (not shown) or the like.
And the vertical waist edge 9 is fixed in parallel at a predetermined interval. An outer wall material (siding material) 10 constituting an outer wall surface is attached to the outside of the horizontal waist edge 8 and the vertical waist edge 9.

However, in the conventional ventilated house, the ends of the torso edges 8 and 9 come into contact with the sash 6 constituting the outer frame of the opening.
The ventilation space 15 of the outer wall formed between the body edges is blocked by the sash 6 of the opening outer frame, and the air circulation is hindered, and the humid air stays.

In order to prevent such a blockage of the ventilation space 15, a method of forming a gap by stopping the end of the torso at the front side without contacting the sash can be considered, but it is difficult to perform the construction on site. A gap cannot be reliably formed between the sash and the body edge. Further, in this case, if the trunk edge is far away from the sash, the fixing of the outer wall material becomes unstable, and a problem arises in that it is difficult to attach a backer for receiving the sealing material when applying a wet seal.

In addition, when the sash is to be formed by selecting an appropriate gap between the sash and the base material in accordance with the size of the base material or the like without substantially changing the dimensions (width dimensions) of the sash itself, or When it is desired to form a gap between the sash and the base material using the sash, it is difficult to cope with the conventional on-site construction method.

Further, as described above, even if a gap can be formed between the vertical and horizontal body edges and the sash at the four side sash portions of the outer wall opening, the ventilation space on the upper and lower two sides and the left and right It is desired to enhance the effect of the ventilation method by communicating with the ventilation space on the two sides to further promote air circulation.

The present invention has been made in view of the above-mentioned prior art, and has good workability, secures ventilation without blocking the ventilation space at the outer frame portion of the sash, and has a vertical trunk edge and a horizontal trunk edge. It is an object of the present invention to provide a sash structure for a house which further promotes air circulation between ventilation spaces when used simultaneously in openings such as windows and sufficiently prevents deterioration of heat insulating material and wood.
