Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel preferably used for a balcony floor or the like.

[0002]

2. Description of the Related Art Conventionally, as a waterproof type balcony floor provided outdoors in a general house, as described in Japanese Utility Model Laid-Open No. 4-73138, a reinforcing plywood is provided on the back surface of a floor panel body made of synthetic resin. It is known that the above is adhered with an adhesive or the like.

[0003]

However, since the floor panel body to which the reinforcing plywood is adhered is almost entirely over the portion where the floor panel body and the reinforcing plywood are adhered, the floor panel is adhered. If both are attached and integrated so that they do not peel off with a chemical agent etc., the thermal expansion and contraction of the floor panel body and the reinforcing plywood will be different. There is a problem in that it occurs or peeling occurs at the interface between the two.

An object of the present invention is to solve the above-mentioned conventional problems and to provide a floor panel in which peeling hardly occurs at the interface between the synthetic resin and the reinforcing material.

[0005]

A floor panel according to the invention of claim 1 is a shallow box-shaped floor panel in which side walls are erected on the entire circumference of the bottom plate. It is characterized in that a plate-shaped body having small holes is embedded therein.

The floor panel according to the second aspect of the present invention is a shallow box-shaped floor panel in which side walls are erected all around the bottom plate, wherein a wire mesh is embedded inside the bottom plate made of synthetic resin. Characterize.

A floor panel according to a third aspect of the present invention is a shallow box-shaped floor panel in which side walls are erected on the entire circumference of the bottom plate, wherein the floor panel is made of synthetic resin and is made of metal combined in a lattice pattern. It is characterized in that the wire rod is buried.

In the inventions of claims 1 to 3, the synthetic resin forming the bottom plate is not particularly limited, and examples thereof include hard synthetic resins such as glass fiber reinforced unsaturated polyester resin (FRP) and hard polyvinyl chloride. Can be mentioned.

In the first to third aspects of the present invention, it is preferable that the bottom plate made of synthetic resin is provided with concave grooves such as a grid pattern on the surface of the bottom plate in order to prevent slippage during walking and drainage of rain.
Further, in order to improve the appearance, a pattern layer such as wood grain or marble pattern may be formed on the surface, and a transparent protective layer may be provided thereon.

In the first aspect of the invention, the material of the plate-like body embedded inside the bottom plate is not particularly limited, and examples thereof include plywood and steel plate. Further, the shape, arrangement, number, etc. of the through holes formed in the plate-like body are not particularly limited, but for example, circles arranged in a radial pattern, a grid pattern, or a zigzag pattern so that the strength does not have directionality. It is preferable to form the holes at substantially equal intervals.

In the second aspect of the invention, the material, thickness and mesh size of the metal wire rod which constitutes the wire mesh embedded in the bottom plate are not particularly limited, but the strength does not have directionality. Thus, for example, it is preferred that the wire be arranged parallel to the edge or diagonal of the floor panel.

In the invention of claim 3, the material, the thickness and the interval of the metal wire rods which are embedded in the bottom plate and are combined in the shape of a lattice are not particularly limited. In order to increase the number of wires, two sets of iron wires whose both ends are folded back in a substantially J shape are fixed to each other so as to be orthogonal to each other.

The method of fastening the metal wire rod in a grid pattern is not particularly limited, and for example, any of welding, adhesion, binding, and the like may be used.

[0014]

According to the floor panel of the present invention, since the plate-like body having a large number of small holes is embedded in the bottom plate made of synthetic resin, the synthetic resin above and below the plate-like body is a plate. It penetrates through the small holes of the sheet and is firmly bonded.

In the floor panel according to the second aspect of the present invention, since the wire net is embedded inside the bottom plate made of synthetic resin, the synthetic resin above and below the wire net penetrates through the through holes of the wire net and is firmly bonded.

In the floor panel according to the third aspect of the present invention, since the metal wire rods combined in a grid pattern are embedded inside the bottom plate made of synthetic resin, the synthetic resin above and below the metal wire rods are made of metal wire rods. It is firmly bonded through the gap.

Embodiments of the floor panel of the present invention will be described below with reference to the drawings. 1 is a partially cutaway perspective view showing an embodiment of the floor panel of the invention of claim 1, FIG. 1 is a partially cutaway perspective view showing an embodiment of the floor panel of the invention of claim 2, and FIG. Item 3
FIG. 3 is a partially cutaway perspective view showing an embodiment of the floor panel of the invention of FIG.

In the invention of claim 1 shown in FIG. 1, reference numeral 1 is a shallow box-shaped FRP floor panel in which a side wall 12 is erected on the entire circumference of a bottom plate 11, and a flange is provided around the opening. The rim 13 extends outward in a substantially horizontal manner. Lattice-shaped concave grooves are formed on the surface of the bottom plate 11 (not shown).

Inside the bottom plate 11, a plywood plate-shaped body 2 having circular small holes 21 formed in a zigzag pattern at substantially equal intervals is embedded in the bottom plate 11, and the FRP layers above and below the plate-shaped body 2 are embedded. Are pierced through the small holes 21 and firmly bonded.

The invention of claim 2 shown in FIG. 2 is the same as the invention of claim 1 except that the wire net 3 is embedded in the bottom plate 11, and therefore, the same parts are provided correspondingly. The symbols are attached and the description is omitted.

The invention according to claim 3 shown in FIG. 3 is the same as the invention according to claim 1, except that the metal wire rods 4 combined in a grid pattern are embedded inside the bottom plate 11. Therefore, the same symbols are given to corresponding parts and the description thereof is omitted.

[0022]

Since the floor panel according to the first to third aspects of the present invention is constructed as described above, peeling does not easily occur at the interface between the synthetic resin and the reinforcing material, and the durability can be improved. I can.
