Description

  The present invention relates to a floor support structure.

  The flooring method is often used for the construction of building floors. In this construction method, a joist is fixed to a wall or the like around a room or a section, and then a support leg is erected at a predetermined position on the floor slab surface, and a floor panel is placed on the support leg. The support leg has a board receiver that receives and supports the lower surface of the panel material constituting the floor panel, and a support bolt that supports the board receiver. The support bolt is often erected and fixed on an elastic body made of cushion rubber. After installing the support legs, place the floor panel on the joist and the upper part of the support leg, fix the panel material with nails etc. to configure the floor panel, and lay the floor material such as flooring material on the floor panel And finish.

  In this flooring method, there is a problem that work efficiency is poor and time is required for construction work when the floor joist is constructed by a woodworker and the others are constructed by a floor construction company. Moreover, since the joist is provided on the wall and the edge of the panel material is placed, the impact sound applied to the floor surface easily propagates, and in particular, the sound insulation against the downstairs is inferior.

  In addition, while the rigidity of the joist is high, the panel material tends to sink due to the load applied to the support legs, and when furniture such as a chiffon is placed, the flatness of the floor surface cannot be maintained and the furniture tends to tilt.

  In order to solve the above technical problem, the applicant of the present invention is a floor support structure in which a height-adjustable support leg provided with an elastic body on the back surface is installed on the floor slab surface and the floor panel is supported by these support legs. The hardness of the elastic body provided on the support leg installed in the periphery of the room or compartment, or the thickness of the elastic body is determined by the hardness of the elastic body of the support leg installed near the center of the room or compartment. A floor support structure was proposed in which the support legs were fixed to the floor slab surface by using an elastic adhesive material that had high hardness or a thin elastic body and had elastic properties after curing (patent) Reference 1).

JP 2000-336902 A

  However, in the structure of Patent Document 1, the support leg is installed near the center of the room or compartment, with the hardness of the elastic body provided on the support leg installed in the periphery of the room or compartment, or the thickness of the elastic body. The hardness of the elastic body is higher than that of the elastic body or the thickness of the elastic body is reduced, and the support leg is fixed to the floor slab surface using an elastic adhesive having elastic properties after curing. For this reason, the floor support structure has a troublesome structure such as a change in hardness, and an improvement has been desired.

  An object of the present invention is to provide a floor support structure that is very simple in structure, can solve the above-described conventional problems, and can omit installation of joists.

  The floor support structure of the present invention is a floor support structure in which a floor panel is supported by support legs installed on a floor slab surface, and a panel material having a square planar shape is used as a panel material constituting the floor panel. In a portion where the square panel material cannot be placed, a floor panel is formed by using a panel material having a rectangular planar shape obtained by dividing the square panel material. The corners of the matching panel members are arranged by shifting in the row direction by half the length of the side of the square so that the corners of the matching panel members are not adjacent in both rows and columns of the matrix arrangement. The panel members that are not positioned at the end in the row and column directions are supported by placing support legs so as to straddle the corners of one panel member and the center of the edge of the other panel member. With matching panel materials The panel members positioned at the ends in the row and column directions are supported by placing support legs so as to straddle the corners of both panel materials, and end in the row and column directions. The panel material located in the portion is supported by arranging support legs at the center of the edge of the panel material, and the support positions on these support legs are positioned on a line in the row and column directions, respectively. It is characterized by that.

  According to the present invention, it is possible to realize the flatness of the floor surface with a very simple structure.
