BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation structure for a house that can support floor panels and wall panels with high precision and high rigidity.

0002

2. Description of the Related Art In recent years, houses using the so-called panel construction method, in which walls, floors, etc. are formed using panels, have become popular.

[0003] In a house constructed using such a panel construction method, 1
Conventionally, the lower part of the wall panel forming the outer wall of the floor is a cloth foundation a provided along the outer periphery of the house, as illustrated in FIG.
Anchor bolt b1 planted on the top surface of the foundation a
It is supported by bolting the base metal c fixed using the base metal fitting c and the lower side of the wall panel p1, and
A floor panel p2 forming the first floor floor was attached via a support fitting d fixed to an anchor bolt b2 protruding from a cloth foundation a.

0004

[Problems to be Solved by the Invention] However, in such a conventional device, the wall panel p1 and the floor panel p2
are fixed individually using base metal fittings c and support metal fittings d, respectively, and together with installation errors and manufacturing errors of each metal fitting c and d, joint variations may occur between wall panel p1 and floor panel p2, Poor construction accuracy.

Furthermore, since the floor panel p2 is fixed using short support fittings d, the bonding strength of the floor panel p2 is poor, and the rigidity against bending and vibration is reduced. On the other hand, the wall panel p2 is unstable and lacks reliability because only the sides are supported.

Furthermore, since the floor panel p2 is installed with its lower surface positioned below the upper surface of the cloth foundation a, the space under the floor is narrowed, resulting in an increase in moisture under the floor due to a decrease in air permeability.

[0007] The present invention is based on bolting the floor panel and the wall panel to a long support member installed along the fabric foundation, and the floor panel and the wall panel are integrally connected to the fabric via the support member. The purpose of the present invention is to provide a foundation structure for a house that can be joined to the foundation and improve construction accuracy and joint strength.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the foundation structure of a house according to the present invention has a U-shaped cross section, with horizontal overhanging pieces extending toward the outdoors above and below a vertical upright piece. A long support material is attached to the base metal fitting fixed to the cloth foundation using anchor bolts planted in the cloth foundation, with a gap between the support material and the top surface of the cloth foundation, and along the cloth foundation, A floor panel forming the floor of the house is bolted to the upright piece facing indoors upon installation, and a wall panel forming the outer wall of the house is placed and bolted to the upper overhanging piece. .

[0009]

[Operation] A long support material is attached to the base metal fitting fixed to the cloth foundation using anchor bolts planted in the cloth foundation, and a floor panel is attached to the upright piece of the support material, and a floor panel is attached to the overhanging piece. Bolt the wall panels to the. Therefore, since the support material that serves as the base for attaching the floor panel and wall panel is installed on the cloth foundation, it is possible to fix the floor panel and wall panel with high rigidity and support the outer wall and floor of the house. It can be formed integrally through the material, improving construction accuracy.

Furthermore, since the wall panel is placed on the overhanging piece of the support material and secured with bolts, the lower surface of the wall panel can be supported over almost the entire length, increasing the mounting strength and reliability, and also improving the reliability of the wall panel. It is possible to eliminate intermediate anchors, etc. arranged approximately at the center in the longitudinal direction, and construction efficiency can be improved.

Furthermore, since the floor panel is bolted to the upright piece of the support material that is attached with a gap between it and the upper surface of the cloth foundation, the installation level of the floor panel can be raised.
It also helps increase the space under the floor and improve ventilation.
