Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION This invention relates to a fixing device for a top plate mounted on a flooring material when a grating material is used as the flooring material.

2. Description of the Related Art It is considered to provide a stage-type floor as an accent in a large space of a building. Generally, a floor having a steel structure is composed of a metal frame and a floor material attached to the frame, and a brace is attached to the frame to provide horizontal strength. But,
In the case of a stage-type floating floor, the brace has a disadvantage that it is exposed to the lower side and impairs the appearance, and the whole becomes heavy and loses its meaning as an accent. To compensate, a grating material that is lightweight and also functions as a brace is used.

Problems to be Solved by the Invention As described above, in a structure using a grating material as a floor material, a top plate is installed on a grating material attached to a floor frame, and a flooring is further provided thereon via a joist or the like. Etc. will be installed. In this case, since the grating material has a structure with many gaps composed of a large number of crosspieces, fixing the grating material to the top plate poses a problem. The purpose of the present invention is to provide a fixing device capable of easily fixing such a grating material to a top plate.

Means for Solving the Problems In order to solve the above problems, in the present invention, at several places of the grating material composed of a large number of crosspieces, a plate is fixed over the upper end of the crosspiece, and a wooden joist is installed. Place the top plate on the top surface of the plate, and screw the screws inserted into the plate from below the plate directly into the top plate so as not to project to the top surface side of the top plate to fix the top plate. Features.

According to the configuration of the present invention, the fixing plate is fixed to the grating material in advance, and the top plate installed on the plate upper surface is fixed with the screw inserted from under the plate. Work can be done.
