[Problems to be solved by conventional techniques and devices]

 Conventionally, the outer wall foundation structure of a wooden house is generally constructed by setting up columns on the foundation at the site and constructing a frame body by straddling horizontal members such as girders and beams between the left and right columns. Reinforcing by providing braces, piercings, studs, etc., filling the inside with a heat insulating material, sticking a moisture-proof polyethylene sheet on the inside of this wall to prevent dew condensation, and further attaching a windproof sheet on the outside. Since it is damp and waterproof, the construction period is long, and the construction cost is high and the economic burden is large.

In order to solve the above-mentioned drawbacks, the present invention secures a frame body framed by columns forming an outer wall, and a wall plate fixed to the indoor side of the wall frame body fitted in the frame body. A panel body with a rigid urethane foam plate stretched on the outdoor side of the plate is manufactured in the factory, and the frame body is erected and fixed on the base on the site, and the panel body is fixed inside this frame body. By attaching an airtight tape to the joints between the wallboards and the wallboards, we provide an airtight and heat-insulating outer wall foundation structure for wooden houses with improved workability in the field.

【Example】

 The drawings illustrate a preferred embodiment of the present invention.

A frame body a made of a frame, such as a pillar or a base forming an outer wall, a horizontal bridge member such as a barrel or a girder, and a wall body 1 of a predetermined size fitted in the frame body a. Produce at the factory. The wall frame body 1 shown in the figure divides the outer wall base space in the frame body a, which is framed by the left and right pillar bodies, the upper and lower bases 4 and horizontal members such as the barrel, into two equal parts in the vertical direction. The figure shows a case where two panel bodies b are fixed to each other. The wall frame 1 of the panel body b is surrounded by the upper and lower lateral stop plates 7 and 7 and the left and right vertical stop plates 8.8, and the vertical stop plate 7 is provided at the center between the upper and lower horizontal stop plates 7 and 7. A middle bar 9 having substantially the same size as the side stop plate 8 is provided upright. A wall plate 2 of the same size as the wall frame 1 is fixed to the indoor side of the wall frame 1, and a rigid foam urethane plate 3 is tightly attached to the outdoor side of the wall plate 2 to form a panel body b. To do.

Since the frame body a and the panel body b are processed with high precision as described above, when the frame body a is erected and fixed on the base 4 at the site, the frame body a substantially as designed is formed. When the wall frame body 1 is fitted in a, the wall frame body 1 is fit tightly between the frame bodies a. In the illustrated embodiment, two wall frame bodies 1 and 1 are fitted in a frame body a, and upper and lower horizontal stop plates 7 and 7, left and right vertical stop plates 8.8 and a column frame from the outside of the wall frame body 1. A and N are nailed together, and the vertical stop plate 8 of the wall frame 1 on the left side of the adjacent comrades and the vertical stop plate 8 of the wall frame body 1 on the right side are nailed to form the panel bodies b and b as a unit. After fixing to the body a, the airtight tape 5 is attached to the jointed portions of the frame body a and the wall plate 2 and the joint portions of the left and right panel bodies c that are joined together.

Since the embodiment is configured as described above, a pillar is erected on the base 4 at the site like a conventional outer wall foundation structure, and a horizontal member such as a girder or a beam is bridged between the left and right pillars. Frame a, which is provided with braces, piers, studs, etc., and is filled with a heat insulating material inside, and a moisture-proof polyethylene sheet is attached to the inside of the wall to prevent dew condensation, and a windproof sheet is attached to the outside. The work at the site where a moisture-permeable and moisture-proof property is attached by attaching a panel is eliminated, and at the site, the frame body a is erected and fixed on the base 4, and the panel body c is fitted and fastened to the frame body a. By simply attaching the airtight tape 5 to the joint between the frame a and the wall plate 2 that are joined together, a highly airtight and highly heat-insulating outer wall base structure is formed, which significantly shortens the site work, and that much Since the construction cost for on-site work is low, the panel body c is composed of the wall frame body 1 and the wall plate 2, Since the flannel c itself functions as a wall foundation, stud, and bracing, the wall strength is large and the strength against wind load and earthquake is improved.

Further, since the wall plate 2 faces the indoor side, the wall plate 2 can be used as it is as an inner wall base material of a wall body without unevenness, so that there is no deviation in internal finish and an internal finish base such as a gypsum board is omitted. You can also do it.

Further, since the rigid urethane foam plate 3 is tightly attached to the outdoor side of the wall plate 2, conduction of heat from the indoor side and heat conduction from the outdoor side is blocked by the rigid urethane foam plate 3 and is excellent. A heat insulating effect is obtained and a ventilation space is formed in the wall between the outdoor surface of the rigid urethane foam plate 3 and the inner surface of the outer wall, so that it is possible to prevent dew condensation inside the wall during the winter period and prevent decay of structural materials and studs. You can

Further, a sound insulation sheet can be stretched between the wall plate 2 and the rigid foam urethane plate 3 to enhance the sound insulation effect.

Further, the above structure is applied to a floor structure of a house, and the same floor frame is formed on the inside of the floor frame fitted to the floor frame and the floor frame fitted in the floor frame. A floor panel body with a floorboard of a size fixed and a rigid urethane foam plate stretched under the floorboard is produced at the factory, and a floor frame is formed on-site by the same means as above, and the floor frame is formed in this floor frame. It is also possible to form a highly airtight and highly heat-insulating wooden house by laying and fixing the floor panel body and applying airtight tape to the joint, or by forming the ceiling panel body by the same means.
