Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a joint suitable for use on floors such as balconies and terraces.

(Prior Art) Watertightness is particularly required for joints between floor panels used in places that come into contact with rainwater, such as balconies and terraces.

As such a joint, for example,
A device related to No. 143054 (Utility Model Application Publication No. 60-48515) has been devised.

The joints of this floor panel are as shown in Figure 8.
The joint walls 19 and 29 are connected by bolts 42 and nuts 43 via a sealing material 40a.

(Problems to be Solved by the Invention) In the above-mentioned conventional floor panel joints, bolt holes must be provided at certain positions in the joint walls 19, 29 and the sealing material 40a, and a thin seal Since the structure is such that waterproofness is maintained by the material 40a, if the bolts and nuts are not tightly tightened, the sealing performance will be poor and water leakage will easily occur.

In addition, it takes time and effort to align the bolt holes in the joining walls of the floor panels, insert the bolts, and tighten them with nuts. You have to get up to do it, which is very inconvenient.

(Purpose of the invention) The present invention solves the above-mentioned drawbacks of the conventional floor panel joints, eliminates the need to raise the floor panels upright when joining floor panels together, and eliminates the need for bolts and bolts. To provide a floor panel joint that can be constructed extremely simply and easily without using nuts, has good waterproof properties, and can completely prevent water leakage.

[Means for Solving the Problems] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 2 5 shows an example of a fastener used at the joint of floor panels according to the present invention, in which both ends of a flat plate 51 are curved downward to form a deep-spreading recess 52 , and the tip has an inner surface facing downward. Holding parts 53, 53 having guide surfaces 54, 54 that are bent so as to spread to
It is said that

FIG. 1 shows an example of the joint part of the floor panels according to the present invention.
Side walls 12 and 22 are suspended from the side edges 11 and 21 of 2, respectively, and after being bent outward, they are further bent upward to form joint walls 13 and 23, and grooves 4 and 4 are formed. A waterproof material 3 is interposed between the joining walls 13 and 23, and the joining walls 13 and 23 are fitted into the recess 52 of the fastener 5 from above, and the holding part 5
3 and 53 sandwich the joining walls 13 and 23.

Further, a lid 6 is fitted between the side edges 11 and 21 of both the plate-like bodies 1 and 2.

At the joint of the floor panels made in this way, the joint walls 13 and 23 of both floor panels A and B and the waterproofing material 3 interposed therebetween are connected to the clamping part 5 of the fastener.
3 and 53, there are no gaps and a watertight structure is obtained.

When the lid 6 is not used, or when the lid 6 is used but water leaks from between the side edges 11 and 21, the water flows through the grooves 4 and 4 and is drained from a drainage channel (not shown). Ru.

For the floor panels used in this invention, synthetic resins such as FRP, hard vinyl chloride, and ABS, and inorganic hardened materials such as asbestos cement can be used, but FRP is particularly suitable because it has good moldability and is lightweight.

As the waterproofing material, various synthetic rubbers, sealing materials, synthetic resin foams with closed cells, etc. can be used, or they can be used in combination.

If the joint wall is provided with bulges 7, 7 on the upper inner surface, as shown in FIG. 4, for example, the fastener 5 will be difficult to come off, and the clamping effect will be further improved.

It is preferable that the clamping part of the fastener has elasticity, and metal, hard synthetic resin, etc. can be used.As shown in Fig. 7, it may be a long body that spans the entire length of the joint wall. As shown in Fig. 5, the holding part 5
4' and 54' may be made thick. Further, as shown in FIG. 6, both ends 5 of the flat plate 51'
5 and 55 may be bent at an acute angle.

Fig. 3 shows a state in which floor panels A, B, and C are joined by the joints of the floor panels of the present invention shown in Fig. 1, and 8, 8... are frames supporting the floor panels A, B, and C. 9 is the subfloor.

(Effect of the invention) At the joint of the floor panel of the present invention, both ends of the flat plate are bent to form a downwardly widening concave part, and the end part is the clamping part of the fastener. Since the joint wall between the two mating floor panels and the waterproof material between them are sandwiched, this joint part becomes watertight and waterproof. When a bulge is provided on the upper outer surface of the joint wall, the concave part of the fastener wraps around the bulge, making it difficult for the fastener to come off, and also provides elasticity to the clamping part even if the thickness of the waterproof material or the joint wall changes. to maintain the clamping effect.

Further, the guide surface provided on the clamping portion has the effect of making it easier to fit the fastener to the joining wall.

To join floor panels together, all you have to do is line up the floor panels at the construction site and press the fasteners over the two adjacent joining walls to make them fit, so even if you are joining a large number of floor panels, you can join them. The joining operation can be performed from any location, and conversely, it can be removed from any joint.

Further, since there is no need for bolts, nuts or special tools, and there is no need to raise the floor panel, construction is extremely simple, easy, and quick.
