Description

  The present invention relates to a floor panel support structure in a double floor structure in which gaps for piping and wiring are provided on a floor base in an apartment house or the like to install a floor panel.

  2. Description of the Related Art In recent years, many double-floor structures have been adopted in which apartment floors, offices, and the like have floor foundation panels installed on the floor base via gaps, and between which piping, wiring, and the like are provided. By using this double floor structure, there is an advantage that it is possible to reduce the necessity of constructing the structural frame when changing piping, wiring, etc. during renovation. In order to construct such a double floor, it is necessary to support the floor panel at a predetermined height from the floor foundation surface, fix the floor panel, and support legs to be connected. It is easy and reliable to fit and support the floor panel with the support legs, and there is a degree of construction freedom that can be installed between the floor base and the floor panel by bypassing complicated piping and wiring In addition, a function such as support in the floor panel and connection such as a cruciform intersection between the floor panels is required.

  For example, there has been proposed a support leg capable of supporting a floor panel and a cross-shaped cross connection between the floor panels (see, for example, Patent Document 1).

  The tile panel connection support leg of Patent Document 1 is a connection support leg for connecting or directly supporting tile panels, and the connection support leg is a connection between the base and the base. The connecting pieces are formed integrally with each other, and the connecting pieces are arranged at equal intervals with the paralleling pieces forming a pair sandwiching the reinforcing ribs of the tile panel with the paralleling direction thereof being directed toward the center of the base plate. The tile panel connection support leg is characterized in that fitting insertion pieces are arranged at positions adjacent to each other in parallel.

In the case of the tile panel connection support leg of patent document 1, it was one of the problems of the connection support leg of the conventional tile panel, the connection tool used for the connection between tile panels, and the tile panel on the base floor surface. Since separate members were used for the supporting legs based on the difference in function, there were many inconveniences due to the increased number of types of members, and the problem of complicated installation work in laying work was solved. Has been.
