Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floor panel in which wooden joists are installed inside a metal peripheral frame and flooring material is laid on top of the wooden joists.

As a floor panel, one in which a peripheral frame is formed using a frame material such as I-shaped steel or C-shaped steel, wooden joists are installed inside the peripheral frame, and a flooring material is laid on the top surface of the wooden joists is known. This floor panel has the advantage of having increased precision and strength in shape due to the metal surrounding frame, and moderate elasticity due to the wooden joists, but it is different from the surrounding frame joists as mentioned above. Since the degree of expansion and contraction differs greatly between wood joists, if wooden joists weaken and contract over time, a step may be formed between the top surface of the surrounding frame and the top surface of the joists, which may cause floor noise. This is particularly a concern in floor panels that have internal heating piping and the like.

In this invention, the joist is constructed on the surrounding frame with the upper surface of the joist protruding slightly above the upper flange of the frame material,
Erect a frame material at the upper corner of the joist along the upper flange and with the top surface of the frame coinciding with the top surface of the joist, and lay flooring material on the top surface of the joist and the upper surface inside the frame material. It is an object of the present invention to provide a floor panel which eliminates the above-mentioned problems and which does not cause floor rumbling even when the joists shrink due to progressing dryness or cracking of the joists. The present invention will be explained below with reference to the drawings.

FIGS. 1 to 6 show an embodiment of the present invention, and in the figures, 1 is a peripheral frame. This peripheral frame 1 is formed by assembling four frame members 2, 2, 3, 3 made of I-shaped steel into a rectangular shape. Between the opposing frame members 2 and 2 of the surrounding frame 1, a plurality of joists 4 having a higher thickness than the frame members 2 have upper surfaces 4a of the joists 4 slightly protruding above the upper flange 2a of the frame member 2. In this state, they are fixed to the lower flange 2b by adhesive or other means, and are constructed parallel to each other at a required distance from each other. A wooden frame member 5 is attached to the upper flange 2 of the frame 2 in the notch 4b at the upper corner of the joist 4.
a along and parallel to this, and the upper surface 5a of the frame member 5
The construction is done by matching the upper surface 4a of the joists 4, and the nails 6
It is attached to joist 4 by. A flooring material 7 is laid on the upper surface 4a of the joist 4 configured as described above and the upper surface 5a inside from the center of the frame member 5, and is fixed to the frame member of the joist 4 with staples 8, and An auxiliary floor material 9 is laid on the upper surface 5a of the frame member 2 and the upper flange 2a of the frame member 2. The floor auxiliary material 9 is placed on the outer upper surface 5a of the frame material 5 and the upper flange 2a of the frame material 2 as described above when the floor panel P of the present invention is laid, and the two adjacent floor panel P
It is also possible to erect one piece of floor auxiliary material 9 on top of it as shown in FIG. As shown in FIG. In some cases, the floor auxiliary material 9 is placed directly on the flange 2a. For fixing the frame material 5 to the joists 4 and fixing the auxiliary material 9 of the floor material 7 to the joists 4 and the frame materials 5, fixing means such as nails 6 or staples are used as described above, and adhesives are also used alone. Alternatively, it is used in conjunction with the above fixing means. However, 11 is joist 4
A heating member such as a pipe for passing steam inserted into a receiving groove 4c formed on the upper surface 4a, and 12 a steadying member. The heating member 11 may not be equipped with this.

In addition, in the floor panel P of FIG. 1, the floor material 7 is placed directly on the upper flange 3a of the frame material 3, as shown by the solid line on the right side of the figure.
As with frame material 2, attach this to the end joist 4.
It is also possible to place the flooring auxiliary material 13 (see the two-dot chain line in FIG. 1) on the outer upper surface 4a of the joist 4 and the frame material 3.

FIG. 7 shows another embodiment of this invention,
A frame material 2 made of C-shaped steel is used in place of the frame material 2 made of I-shaped steel of the floor panel P shown in FIGS. 1 to 6. Also in this floor panel P, the mutual relationships among the frame material 2, joists 4, frame materials 5, floor materials 7, and floor auxiliary materials 9 are the same as those in FIGS. 1 to 6, so the explanation thereof will be as follows. Omitted. In this example, the adjacent floor panels P, P are joined together with bolts 14 with the frame members 2, 2 placed back to back.

FIG. 8 shows an example of a second floor unit using the floor panel P of the present invention as a floor ceiling. It is supported horizontally by 19 and functions as a floor and a ceiling. Note that there are various ways of using the floor panel P of the present invention other than those shown in the figure, and the method is not limited to the one shown in FIG.

In the floor panel P of the present invention, a plurality of wooden joists are arranged in parallel between the opposing frame members with the upper surfaces of the joists slightly projecting upward from the upper flanges of the frame members, and A frame member is installed at the upper corner part along the upper flange, with the top surface of the frame member matching the top surface of the joist, and flooring material is laid on the top surface of the joist and the upper surface inside the frame member. The joist is its origin
Even if it becomes lower due to drying or other reasons, it will not become abnormally lower than the frame material.
Furthermore, the flooring material ends at the upper surface of the inside of the frame material, and auxiliary flooring material is laid separately from the flooring material on the upper surface of the outside of the frame material and the upper surface of the frame material, so that the shrinkage of the joists is prevented. Since this is absorbed by the structural members, problems such as floor noise will not occur.
