Description

[Detailed Description of the Invention] This invention relates to a subfloor structure, and its purpose is to provide a subfloor structure in which horizontal leveling of the floor and installation of joists can be performed extremely easily.

In the conventional floor substructure, as shown in Fig. 1, a subfloor material 2 such as a deck plate is fixed onto a frame member 1 such as a beam, and a concrete material 3 is poured onto the subfloor material 2 such as a deck plate. However, there was a problem in that it was extremely difficult to level the concrete material 3 horizontally when pouring it.

Furthermore, a joist 4 is attached to the upper end of this concrete material 3.
Since the joist 4 was placed on the joist, there were problems in that the position of the joist 4 was misaligned or that it was extremely difficult to level the joist 4.

This invention was made to solve the above-mentioned problems, and one embodiment of this invention will be described in detail below based on the drawings.

Fig. 2 shows an external view of the mounting hardware used in this invention. In Fig. 2, reference numeral 5 denotes a mounting hardware formed by integrating side plates 6, 6 and a bottom plate 7 into a U-shaped cross section. Projections 8, 8 are provided protruding outward from both side plates 6, 6 of 5 .

The protrusion position of this protrusion 8 is provided at least at a location higher than the bottom plate 7 by the desired concrete depth h.

FIG. 3 shows a subfloor structure according to an embodiment of this invention using such mounting hardware 5. In the drawing, 1 is a frame member such as a beam, and 2 is a deck plate attached to this beam. A bottom plate 7 of a mounting hardware 5 is fixed to a predetermined position of the flooring material 2 by any means such as bolting.

3 is concrete material, this concrete material 3
is driven to a depth where the protrusion 8 of the mounting hardware 5 is buried.

That is, when pouring the concrete material 3, the protrusion 8 of the mounting hardware 5 is used as the height target.

Reference numeral 9 denotes a joist, and this joist 9 is attached between the side plates 6, 6 of the mounting hardware 5 by a required method such as bolting or nailing.

As described above, in the flooring structure according to this invention, a flooring material such as a deck plate is attached to a frame member such as a beam, and a U-shaped cross section is placed on the outside of both side plates at a desired position of this flooring material. The bottom plate of the mounting hardware with protrusions at the required positions is fixed, concrete is poured up to the protrusions of the mounting hardware, and joists are fixed between the plates on both sides of the mounting hardware. Because it is a ground structure, it is possible to level the concrete material using the protrusion of the mounting hardware as a reference, making it extremely easy to level the concrete material, and since the joists are attached to the mounting hardware, it is possible to level the concrete material horizontally. Since the strength is supported by the frame material through the joist, it is extremely suitable for strength, and the mounting position of the joist is determined by the mounting hardware, which greatly improves the accuracy of the joist installation position. be effective.
