At this time, the height of the support leg 51 can be adjusted while the floor panel 22 is placed, and if the proper use of the support leg 1 is appropriately performed according to the laying state of the floor panel 22, the work can be efficiently performed. I can do it.

Therefore, according to the above embodiment, since no joist is required, the work can be carried out only with the support legs and the floor panel, so that the work can be carried out only by the floor workman and the conventional woodworker can use the work. Since there is no work, the work efficiency is good and the construction period is shortened. In addition, since the front support legs are fixed to the floor slab surface using the elastic adhesive material 27, the front support legs are firmly adhered to the floor slab surface, and the fixing of the front support legs is stabilized, and the elastic adhesive material 27 is hardened. After that, it has elastic characteristics, so that the elastic force of the supporting legs is not impaired.

Further, since the supporting legs are used in two rows at the periphery of the compartment such as a room when the elastic action is provided as compared with the conventional joist 31, the floor panel 22 sinks against the heavy object. Fixed the problem that furniture was leaning forward. In addition, the floor panel on the wall side also prevents floor impact downstairs due to the elastic action of the edge support legs, and has good sound insulation. On the other hand, the floor panel is placed directly on the board support of the support legs and fixed with nails, so that processing such as opening the floor panel is not required, the support pitch between the support legs can be set freely, and the workability is excellent. .

Also, in a section having a large floor surface, a floor panel is not divided into sections such as a living room, a Japanese-style room, and a kitchen at first, but is laid all over the floor panel and then divided into a plurality of sections by partitioning. When the preceding laying method is used, the support legs can be set in advance at a position corresponding to the periphery of a section such as a room, and the floor support structure can be constructed for each section. For this reason, the floor support structure
The floor support structure using the support legs can be applied not only to the position on the wall side but also to a free section such as a position near the center of the room.
