Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel joining structure, and more particularly to a floor panel joining structure suitable for use on a floor exposed to rainwater such as a balcony, terrace, or veranda.

[0002]

2. Description of the Related Art As a floor structure for balconies, terraces, balconies, etc., a floor panel made of synthetic resin, FRP (fiber reinforced resin) or the like is formed into a substantially flat plate, and is placed on the floor structure such as roots, floor piers or crossbars. It is known that a plurality of sheets are arranged side by side.

By the way, since floors such as balconies, terraces and balconies are exposed to rainwater, in the floor structure using the above-mentioned floor panels, waterproofness is particularly required at the joints between the floor panels.

Conventionally, as a joint structure for joining floor panels used in such a place where waterproofing is required, there is a conventional method.
No. 0-48515, Utility Model 5-40476 and Utility Model 7-15930 are proposed.

In Japanese Utility Model Laid-Open No. 60-48515, the side edges of the flat plate-like main body portions of the floor panels to be joined to each other are bent downward to form side walls for joining, and the side walls of the two floor panels are connected to each other. A structure is adopted in which bolts and nuts are tightened with a sealing material interposed between them.

On the other hand, in Japanese Utility Model Laid-Open No. 5-40476 and Japanese Utility Model Laid-Open No. 7-15930, a joint groove having a substantially U-shaped cross section is formed along the side edge of the flat plate-shaped main body of one floor panel, and the joint groove is formed. The tip of the rising portion corresponding to the outer side wall is bent further outward at a position lower than the flat plate main body to form a flat portion, and the side edge of the flat plate main body of the other floor panel is bent downward. Side wall is formed, the side wall is inserted into the above-mentioned joining groove, an elastic body is interposed between the lower end of the side wall and the bottom surface of the joining groove, and it is formed outside the joining groove of one floor panel. A structure in which an elastic body is interposed between the upper surface of the flat portion and the lower surface (back surface) of the flat plate-shaped main body portion of the other floor panel is adopted.

[0007]

Among the above-mentioned conventional floor panel joining structures, in the structure of Japanese Utility Model Laid-Open No. 60-48515, water tightness is obtained by the tightening force of bolts and nuts, but the tightening force is weak. In this case, not only the sealing performance deteriorates and water leakage easily occurs, but also it takes time and effort to insert the bolts by aligning the bolt holes on each side wall for joining, and further, all floor panels are raised and fastened. It is necessary and there is a problem that the workability is extremely poor.

On the other hand, in Japanese Utility Model Laid-Open No. 5-40476 and Japanese Utility Model Laid-Open No. 7-15930, since the thin lower end surface of the side wall inserted into the bonding groove is bonded in contact with the surface of the elastic body, the bonding is performed. Due to the difference in dimensional accuracy and deformation of the two floor panels that should be made, it is actually difficult for the elastic body in the joint groove to exert complete water blocking performance, and the dynamic load on the floor surface When the side wall in the joint groove moves due to action or the like, the elastic body breaks or the deterioration is accelerated,
There was a problem with respect to the durability of the waterproof performance.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a joint structure for floor panels, which has good workability and can maintain good water-stopping performance for a long period of time. .

[0010]

The floor panel joining structure of the present invention achieves the above object by adopting the following constitution.

That is, as illustrated in FIG. 1, the side edge 11 of the flat plate-shaped main body portion 10 of one floor panel 1 is bent downward and then extended outward substantially in parallel with the main body portion 10.
Further, the extending end is bent upward to a position lower than that of the main body portion 10 to form the joining groove 12 that opens upward along the side edge portion 11.

The flat plate-shaped main body 2 of the other floor panel 2
The side edge 21 of 0 is bent downward and then extends outward substantially parallel to the main body section 20 to form a protruding flat portion 22 along the side edge 21.

Then, the protruding flat portion 2 of the other floor panel 2
2 is inserted into the joint groove 12 of one floor panel 1, and
The projecting flat portion 22 is covered with a waterproof material 3 made of a bag-like elastic material that covers the upper and lower surfaces of the projecting flat portion 22 and has a cavity 34 along the tip of the projecting flat portion 22. . At this time, in the water blocking material 3, the side surface portion of the cavity 34 is in close contact with the inner side surface 12b of the joint groove 12, and the portion 32 that covers the lower surface 22b of the protruding flat portion 22 is the protruding flat portion 22. The lower surface 22b and the bottom surface 12a of the joining groove 12 are compressed.

Here, in the present invention, as the material of the floor panel, synthetic resin such as vinyl chloride resin, or FRP in which such synthetic resin is reinforced with fibers can be used.

As the material of the waterproofing material 3 made of an elastic material in the present invention, various rubbers, soft vinyl chloride resins, or foamed resins such as foamed polyethylene and foamed polypropylene can be used.

<Operation> A projecting flat portion 22 projecting in the horizontal direction along the side edge 21 of the other floor panel 2 is fitted into the joint groove 12 of the one floor panel 1 and is covered with the projecting flat portion 22. A part 32 of the water blocking material 3 is planarly contacted by the lower surface 22b of the projecting flat portion 22 and the bottom surface 12a of the joint groove 12, and is sandwiched in a compressed state by them. Therefore, even if there is a slight difference in size between the floor panels 1 and 2, good water blocking performance can be obtained. Also, each floor panel 1,
Even if the joining groove 12 and the projecting flat portion 22 move relative to each other due to the action of a dynamic load with respect to 2, the portion 32 of the water blocking material 3 sandwiched between them makes surface contact with both of them. Therefore, it is hard to slip and does not break or deteriorate.

The hollow portion 34 provided in the water blocking member 3
Is the tip of the protruding flat portion 22 and the joining groove 1 facing the tip.
The gap between the second side surface 12b and the second side surface 12b is filled up, and even if there is a slight dimensional difference or deformation between the two sides 12b, it is absorbed by the deformation of the cavity 34 and water leakage is effectively prevented.
