面、３６は盛り土である。 The floor panel 5 is attached to a frame 24 as shown in FIG. 2d.
It is formed by pasting the plate material 25 on the frame 24.
A joist 26 is provided inside. In order to attach the floor panel 5, receiving metal fittings 30 and 31 are fixed to the outer surfaces of the supporting member 2 and the connecting plate 11 described above. That is, as shown in FIG.
The floor panel 5 is supported by the floor beam 1 by placing the end portion of the floor panel 5 on the floor beam 1. Further, as shown in FIG. 2c, the bolt 27 is passed through the hole 32 of the presser fitting 29 formed by bending and extending the presser pieces 28 on both sides, and the bolt 27 is screwed into a nut or the like fixed to the upper surface of the floor beam 1. By doing so, Figure 5 a, b
The end portion of the floor panel 5 is held down by the holding piece 28 of the holding fitting 29 as shown in the figure, so that the floor panel 5 is sandwiched and fixed between the receiving fitting 30 and the holding fitting 29. Attach the wood screws 33 etc. from the holding piece 28 of the holding fitting 29 to the frame 2 of the floor panel 5.
4 so that the presser metal fitting 29 is fixed to the floor panel 5. The other parts of the floor panel 5 are supported on the cloth foundation 4 by floor panel support fittings 34. Incidentally, by enlarging the floor panel 5 and fixing it with hardware as in this embodiment, the fear of floor noise can be eliminated. In Fig. 1, 35 is the ground, and 36 is the mound.

におこなうことができるものである。 Although the floor panel 5 can be supported by the floor beam 1 as described above, a load is applied to the center of the floor beam 1, causing the center of the floor beam 1 to bend downward. In this case, the downward displacement of the supporting member 2 acts as a tensile force on the reinforcing member 3, which is received by the anti-extension force of the reinforcing member 3. As a result, the downward displacement of the supporting member 2 In other words, downward deflection of the floor beam 1 is prevented. Therefore, the floor panel 5 can be supported by the floor beam 1 without the need to support the central portion of the floor beam 1 by the floor bundle. In addition, since the floor beam 1 reinforced with the reinforcing material 3 has an approximately inverted triangular shape as a whole, as is clear in Fig. A space is created through which workers can easily pass through, allowing them to easily install and inspect piping and wiring under the floor.

As described above, in the present invention, the support material is attached to hang down approximately at the center of the floor beam in the longitudinal direction, and the reinforcing material is disposed diagonally between both ends of the floor beam and the lower end of the support material. The ends of each reinforcing material are connected and fixed to the ends of the floor beams and the lower ends of the supports, respectively, and the floor beams are placed between opposing cloth foundations, and each end of the floor beams is connected to the cloth foundations. Since the floor panels are supported and fixed by the floor beams, even if a load is applied to the center of the floor beams, this load will be borne by the reinforcing materials through the support materials, and the floor panels will be supported by the floor beams. Floor panels can be supported by floor beams without the need for support by bundles, and the frost heave problem that occurs when using floor bundles and bundle foundations or independent foundations that support the floor bundles is eliminated, In addition, the labor required for constructing a bundle foundation, etc., which is required when floor bundles are used, is not required, and the labor required for construction can be reduced. Furthermore, even though the floor beams were reinforced with reinforcing materials, the overall shape of the floor beams was approximately an inverted triangle, so the reinforcing materials did not get in the way near the fabric foundation. A large space will be created,
By passing through this part, it is possible to install and inspect pipes and wiring under the floor without any problems. Moreover, one end of the reinforcing material is connected to the end of the floor joist via a connecting plate, and the receiving metal fitting is attached to the outside surface of the support material below the top surface of the cloth foundation so as to protrude laterally, and the length of the floor joist is A receiving metal fitting is fixed to a part of the outer surface of the above-mentioned connecting board at the horizontal end so as to protrude sideways at approximately the same level as the receiving metal fitting of the supporting material, and the end of the floor panel is fixed to a part of the outer surface of the above-mentioned joining plate, so that the end of the floor panel is lower than the above-mentioned fabric foundation. Because it is placed on the above-mentioned receiving metal fitting located below,
The floor panel is placed not on the top surface of the floor joist, but on a receiving metal fitting provided on the lengthwise end of the floor joist and on a supporting member hanging approximately at the center of the floor joist, and the receiving metal fitting is located below the top surface of the cloth foundation, and when the top surface of the floor panel is determined, the thickness of the floor panel can be increased.For example, in order to obtain the necessary floor thickness in cold regions, it is necessary to raise the floor level. It has the advantage of being able to be secured without having to worry about it.
