BACKGROUND OF THE INVENTION The present invention is applicable to general houses and the like.
The present invention relates to a floor structure for a house in which both ends of a long structural member are supported by supporting members such as columns and walls.

[0002]

2. Description of the Related Art A floor structure in a general house needs to be formed to have sufficient strength to support a load transmitted from a floor or a wall. Conventionally, such a floor structure for a house is formed by simply forming a structural material into a shape that does not cause a deflection beyond a certain limit under a load, and supports both ends of the structural material by supporting members such as columns and walls. I was trying to receive various loads.

However, such a conventional residential floor structure, as shown in FIG. 5, is particularly effective when the floor structure of a room having a short span and the floor structure of a room having a long span are adjacent to each other. It caused various problems. That is, the floor structure of a room with a short span may have lower strength than the floor structure of a room with a long span, and originally the structural material 22 may be thin, but especially in the 2 × 4 construction method, the floor of the upper floor is the same. Since it is necessary to make the height, and since the structural member 22 and the adjacent structural member 21 are supported by the same supporting member 20, only the structural member 22 cannot be thinned and must have the same shape as the structural member 21 in the end. Therefore, there is a problem that extra cost is generated. Especially today, when the unit price of timber is soaring, using an unnecessarily thick structural material had a great influence on the entire housing cost.
