Pour the ohiki material on top,
In this state, after adjusting the adjustment nut to make the level constant in all bundle parts, pour the joist material onto the large joist material, and then place and fix the flooring material on top of the joist material. It was then turned. As a result, there is an extremely large amount of work to be done on site, and despite the desire to shorten the construction period and improve the efficiency of turning, the construction period has become long. Furthermore, a large amount of materials such as large lumber and joists are required, which, together with the rise in labor costs for on-site work, causes an increase in costs.

Therefore, the present invention consists of a panel plate to which a support metal fitting is fixed, a hollow bundle member having a bundle pipe with a thread formed thereon, and a connecting metal fitting, and the thread of the bundle pipe is screwed into the support metal fitting, and the bundle member is connected to the hollow bundle member in the hollow bundle member. It is constructed by fixing it to the floor slab at the section, and connecting adjacent panel boards using connecting fittings, and does not require any lumber or joist material, and the structure is simple and can be constructed at low cost. To provide an excellent floor device in which level and horizontal adjustment can be carried out accurately and reliably, the elasticity of the floor is continuous without change even at the panel board connection part, and furthermore, it has an under-floor space of a predetermined height. The purpose is to

In addition, the present invention places the bundle member fixed and integrated on the panel board on the floor slab, and then passes the bundle member through the hole in the panel board and the hollow part of the bundle member from above the panel board to the floor slab. The panel board is fixed to the panel board, and the bundle pipe is rotated from above the panel board to adjust the level and horizontality of the panel board.
By making the panel boards and bundle members into a unit, the work required on site is extremely reduced, and by fixing the bundle members and adjusting the level and horizontality of the panel boards from above the panel boards, the work related to the subfloor equipment can be greatly reduced. The object of the present invention is to provide a method for constructing a floor device that saves labor and facilitates construction, shortens the construction period, and improves the efficiency of construction.
