[Industrial applications]

 It is related to the wall structure of a wooden framed house with good workability and durability, high heat insulation, and high airtightness.

[0002]

[Prior art]

 In a conventional wooden framed house, the space between columns is reinforced by studs, braces, horizontal joints, etc. to give strength, and a heat insulating material such as glass wool is inserted between the gaps of these members to provide heat insulation. In addition, since these members are naturally easy to ventilate, a high-tightness seal sheet is attached to the entire surface of the building.

However, the above-mentioned construction method has a drawback in that the construction cost is large because the number of members is large, the work is complicated, and skill is required. As a countermeasure to this, a panel construction method was devised, in which so-called wooden frame panels in which studs, braces, horizontal shafts, etc. were surrounded by wooden frames were produced at the factory, and the wooden frame panels were only incorporated locally. However, even with this method, there is no choice but to carry out airtight construction locally, which is still insufficient to reduce construction costs and cope with the shortage of skilled workers. Further, the panel manufacturing process itself is the same as the conventional one, and it takes time and labor.

Therefore, the wooden frame panel construction method does not contribute much to the reduction of the work amount of the whole process and the improvement of the airtightness of the house, since the number of days of on-site construction is reduced as compared with the conventional method. Regarding the improvement of airtightness in a wooden frame panel, there is a foamed urethane foam injection panel disclosed in JP-A-5-171709. The labor of creating a wooden frame panel is the same as before.

Recently, as an improvement of these methods, a method of using a sandwich panel in which a foamed plastic is used as a core material and a skin material such as plywood is laminated on both sides has been devised. When sandwich panels are used, heat insulation and airtightness are improved, and the panel preparation work can be reduced. However, these conventional methods of using sandwich panels have not been able to maximize the benefits of using panels due to problems in panel mounting methods.

[0006] For example, in Japanese Patent Laid-Open No. 3-55327, since the sandwich panel is directly driven from the outside to the pillar with a nail or the like, it is necessary to have a strength structure mainly of the pillar. Therefore, it is necessary to improve the strength of the frame as compared with the conventional one. For this reason, the large-diameter laminated lumber is used in this patent, and there is a drawback that a heavy machine is required to transport the members. Further, in Japanese Patent Laid-Open No. 6-49928, the sandwich panel is attached by making notches in the panel and columns and columns or girders, and fitting them together. With this method, the work of making each notch increases, and because the members that have made notches mutually are combined, the mounting position and procedure of the members are fixed, so the flexibility at the construction site becomes poor. There was a flaw.

[Problems to be solved by the device]

 It is intended to provide a wall structure for a wooden framed house that has good workability and excellent airtightness.

[0008]

[Means for Solving the Problems]

 According to the present invention, a wall panel constructed by sandwiching both sides of a flat core material made of rigid foam plastic with a skin material is fitted into a rectangular frame composed of a pillar and a base, a girder or a beam. The wall panel is joined to the pillar and the base, the girder or the beam by the metal plate at least at two points on the diagonal line, and the core material of the wall panel has at least one groove that vertically penetrates the core material. It is in the wall structure of the wooden framed house where the

The present invention will now be described in more detail with reference to the drawings. FIG. 1 shows a rectangular frame constituted by joining columns 1, 1'to a base, girders or beams 2, 2 ', and a wall panel 3 fitted in the frame. The wall panel 3 is a rigid foam plastic. It is constructed by sandwiching both sides of a flat plate-shaped core member 4 made of black and white with a skin member 5, and a through groove 7 is formed in the core member 4.

Examples of the core material include rigid vinyl chloride resin foam, rigid urethane foam, and expanded polystyrene, and those having closed cells are preferable. Examples of the skin material include structural plywood, particle board, FRP board, metal plate, concrete board and gypsum board. From the viewpoint of heat insulation, wood is preferred. The through-grooves 7 are used as a route for wiring in the wall and piping, and generally, it is preferable that the number of the through-grooves 7 is 2 to 3 per 1 m of the panel width. The groove diameter may be 1/2 or less of the panel thickness, and the cross-sectional shape may be arbitrary.

FIG. 2 shows an example of the present invention in which a wall panel is fitted in a frame and is connected to a pillar and a base, a girder or a beam with a metal plate 8. The metal plate is attached by known means such as screws, screw nails and adhesives.

FIG. 3 shows a state in which a rod-shaped joint material made of soft foam plastic is provided on the exposed core material around the wall panel. It is preferable that the joint material is provided with a groove formed in the core material so as to fill the groove and rise above the surface. Examples of the material of the joint material include sponge rubber, soft vinyl chloride resin foam, soft urethane foam, polyethylene foam, EVA foam, and the like, and those having closed cells are preferable.

FIG. 4 shows an example in which, when the thickness of the wall panel is smaller than that of the frame member, the end portions are joined using a metal plate having a vertical portion instead of a simple flat plate.

[0014]

[Effect of device]

 A house with the structure of the present invention achieves high heat insulation and airtightness with a hard foam core material, and the sandwich structure with the skin material not only improves the skeleton function but also increases the proof strength against vertical load, so it is durable. Excellent in performance, and the number of members is greatly reduced by eliminating the need for members such as studs and coffins, which makes the construction quick and easy.
