Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation structure for a building used for floors, ceilings, walls and the like.

[0002]

2. Description of the Related Art As a well-known metal base material, there is a steel floor base for a Japanese Industrial Standard JISA6519 gymnasium.

[0003] A base material having a special structure developed for OA floors such as a computer room is also known.

[0004] Further, as a well-known base structure of a building (especially, for a general house), for example, a wooden pulley is disposed on a slab under the floor and crossed over the pulley. In some cases, a wooden joist is arranged and a floor material is arranged thereon. In this case, as a countermeasure for termites, a wooden pulling and joist is often used by impregnating a chemical for termite extermination.

[0005]

However, in the case of the above-mentioned base structure using the steel base material for a gymnasium, since it is limited to the use in a gymnasium, not only is it difficult to lower the floor from the structure, but also the general-purpose structure is used. However, there is a problem that it is difficult to disseminate generally because of lack of performance and high cost.

[0006] In the case of the OA floor, many support members having a complicated structure are interposed between the underfloor slab and the floor material, and a joint between each support member and the floor material is provided. Has a structure in which the upper surface of the support member is fitted by applying special processing to the lower surface of the flooring material, complicating the structure, increasing the number of parts and processing steps, and increasing the cost. There is a problem. In addition, the workability deteriorates because much effort is required to adjust the height of each support member. In addition, there is also a problem that the OA floor is exclusively used for the OA floor, and thus lacks versatility and is hardly widely used.

[0007] Further, in the case of constructing a floor base structure by a combination of a wooden pull and a joist, there is a limit to the reduction of the floor base structure, the structure itself becomes complicated, and the assembling work must be complicated. There is a problem that can not be obtained. In addition, there is a problem that simply impregnating the used wood with chemicals is not a complete measure against termites. Furthermore, it can be said that this is a regression to an era where so-called resource saving should be achieved, in which the use of finite timber resources is reduced as much as possible.

[0008] One of the major reasons why metal base materials have not been used in ordinary houses is that carpenters do not like to use them because of the complicated structure and construction method.

[0009] Under the circumstances described above, there is an increasing expectation for a foundation structure for a building using a metal foundation material which is extremely simple in structure and can be constructed at low cost without requiring special techniques.

[0010] The present invention has been made in view of the above points, and in a foundation structure for a building using a metal foundation material, the structure is extremely simplified, and it can be easily implemented even by persons without special skills. It is intended to be able to reduce the cost significantly.
