Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a floor panel that can be placed directly.

<Prior Art> Conventionally, it is known that a direct-standing floor panel has legs fixed to the four corners of the back surface of the panel body using an adhesive or screws (Japanese Patent Laid-Open No. 51-66129).

<Problems to be solved by the invention> The above-mentioned floor panel has a structure in which the legs are fixed only by adhesive force or screwing force.

Therefore, the bending deformation force of the panel body concentrates on the legs that rest the lower surface on the foundation floor and the parts that are fixed to the panel body, causing peeling and loosening of the screws, which may cause the legs to come off the panel body. There is.

The present invention was made in view of the above-mentioned conventional circumstances, and its purpose is to prevent the legs from coming off in a direct-standing floor panel in which the legs are fixed to the four corners of the back surface of the panel body.

<Means to solve the problem> The technical measures taken to achieve the above purpose are:
At the four corners of the back side of the panel body whose back side is reinforced with a metal plate, receiving metal fittings are punched out from the metal plate to form a fitting space for positioning the legs between the back side of the metal plate, The gist is that the legs that fit into the fitting spaces are fixed to the panel main body.

<Operation> According to the above technical means, the flexural deformation is kept small by reinforcing the backing of the metal plate, the flexural deformation force (peel force) applied to the fixed part of the leg is weakened, and the fixed part of the leg is strengthened by the fixed force. It is supported in cooperation with the fitting receiving force of the receiving metal fitting which is punched out from a metal plate.

<Effects of the invention> As described above, the invention reduces the amount of deflection through the reinforcing effect of the metal plate and reduces the deformation force acting on the fixed parts of the legs, while also punching out the legs. Since they are sandwiched between the receiving metal fittings and the back surface of the metal plate, the legs are firmly and stably fixed to the panel body, and will not fall off.
Furthermore, since the receiving bracket indicates the leg fixation position, there is no need for pre-work such as marking lines to mark the leg fixation position, making the leg fixation work much simpler. can be converted into

<Example> Next, an example of the present invention will be described based on the drawings.

In Figures 1 and 2, 1 is the panel body;
2 is a receiving metal fitting, and 3 is a leg portion.

The panel body 1 is formed by backing and reinforcing a metal 1b on the back side of a panel body 1a made of G.R.C or mortar and having a square shape in plan view.

The metal 1b is formed by punching out upward-facing pieces 1b' scattered over the entire area, and these shaped pieces 1b' bite into the panel body 1a and are joined together by press forming. It is integrated with the panel body 1a.

Further, receiving metal fittings 2 for positioning the leg portions 3 are punched downward at the four corners of the metal 1b.

The receiving fitting 2 has a vertical piece part 2a hanging down with the same length as the thickness of the leg part 3, and a supporting piece part 2b horizontally bent from the lower end of the vertical piece part 2a.
It has a shape.

Further, the width of the receiving metal fittings 2 is made slightly longer than the width of the leg portion 3, and as shown in FIG. 1, two pairs are placed back to back with the center as the boundary.

The leg portion 3 is made of the same material as the panel body 1 and has a square shape in plan view and has a thickness equal to the length of the vertical piece portion 2a, and is formed within a fitting space 2c composed of the vertical piece portion 2a and the support piece portion 2b. The upper surface is fixed to the panel main body 1 with an adhesive 4 to be integrated with the panel main body 1.

Therefore, in the direct-mounting type floor panel, the molded-in pieces 1b', which have a strong biting force into the panel body 1, are formed as protrusions on the metal plate 1b, so that both of them, that is, the metal plate 1b
The panel body 1 forms a joint structure in which the panel body 1 is joined in a biting state, thereby reducing the bending deformation without increasing the thickness, reducing the peeling stress generated in the fixed part 4' of the leg part 3, and Since the leg portions 3 constitute a support structure in which the fixing force of the adhesive 4 and the fitting force to the receiving metal fitting 2 work together to support the leg portions 3, the leg portions 3 continue to maintain a more stable fixed state.
