BACKGROUND OF THE INVENTION
The present invention supports a wooden material floor material (for example, a plate material or a square material) at a plurality of locations with respect to a floor base or a floor slab surface, and lays these floor materials up and down with nails (or partial adhesion). The present invention relates to a stacked floor structure, and particularly to a floor noise prevention floor in which floor noise is prevented from being generated due to a difference between floor materials.
[0002]
[Prior art]
For example, various double-floored structures are used in apartment buildings. In these floor structures, floor squealing phenomena such as squeaking may occur due to a load acting on the floor surface.
[0003]
[Problems to be solved by the invention]
In other words, this is because if the wooden materials are fixed to each other with nails or fixed to the nails and partially bonded (this phenomenon does not occur if the entire surface is bonded) and supported on the floor slab surface, the plates will be separated. Bending deformation such as bending is likely to occur, and the surfaces that are in contact with each other are shifted (or rubbed) due to a difference in curvature at the time of deformation, and abnormal noise is generated. In particular, when this bending deformation increases, it starts to slide at a certain point and a flooring phenomenon occurs.
[0004]
Such a phenomenon is not particularly limited to the double floor structure for an apartment house, and even in the floor structure of a general detached house, it occurs in floor materials of the same structure and is comfortable. In order to achieve a comfortable living environment, prevention of such flooring phenomenon is an important issue.
[0005]
In view of the above circumstances, an object of the present invention is to provide a flooring prevention floor that can effectively prevent a flooring phenomenon.
[0006]
[Means for Solving the Problems]
That is, the invention according to claim 1 supports the floor material made of wood material at a plurality of locations with respect to the floor base or the floor slab surface, and fastens these floor materials with nails or screws at appropriate intervals. in multiple partnered by stacking and becomes floor structure up and down by attaching or partially adhered, wherein a rough surface processing applied more on at least one sides of the surface in contact with each other flooring, No. 80 the surface to be roughened (JIS R6010 ) A rough surface is formed by sanding using an abrasive having the following particle size .
[0007]
Further, in the invention according to claim 2, as the plurality of flooring materials, a floor panel and a floor panel, or a finishing material is provided on the floor panel, or a floor panel and a finishing material, and further a carpet on the finishing material. In addition, the surface of the finishing material in contact with the carpet and the one surface of the floor material in contact with each other are roughened by using a pulling, a joist and a finishing material . Furthermore, the invention described in claim 3 is obtained by roughening both surfaces of a wooden material floor material that come into contact with each other.
