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 tightened weakly, 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 problem) Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an example of the joint part of the floor panels according to the present invention, in which the floor panels A and B have recesses 12 and 22 formed outward below the ends 11 and 21 of the plate-like bodies 1 and 2. Side walls 13 and 23 are respectively provided which are curved, lower ends 14 and 24 of the recesses 12 and 22 are located outwardly than the ends 11 and 21, and support legs 15 are provided below the lower ends 14 and 24. 25 are provided, respectively, and the floor panels A and B are butted against each other at the outer surfaces of the support legs 15 and 25. FIG. 2 shows the fixture 3, which has two clamping pieces 32, 32 facing each other on the surface of the board 31, which are inclined upward toward the center of the board 31 and have a strong elastic restoring force. It is provided. The two support legs 15, 25 which are abutted around the peripheries of the clamping pieces 32, 32 of the fixture 3 are strongly clamped by the clamping pieces 32, 32. Furthermore, the grooves formed by the recesses 12 and 22 of the floor panels A and B are compressed and filled with an elastic waterproofing material 4 having a cross-sectional area larger than the cross-sectional area of the grooves.

Further, the gap between the end portions 11 and 21 of the floor panels A and B is filled with a stretchable joint material 5 such as silicone sealant.

The floor panel joints made in this way are connected by the strong elastic restoring force of the two clamping pieces 32, 32, which are provided facing each other and slanting upward towards the center of the fixing bracket 3. Since the support legs 15 and 25 are in strong pressure contact, the support legs do not separate from each other, and the elastic waterproof material 4 is placed in the groove formed by the recesses 12 and 22 of the side walls 13 and 23.
When it is compressed and filled, the elastic waterproofing material 4 comes into close contact with the inner surface of the groove, and the waterproofness becomes complete.

In addition, in the joint part of the floor panels according to the present invention, the supporting legs of the floor panels to be joined are inserted and clamped by pushing apart the space between the two clamping pieces provided on the surface of the fixing fittings, and the floor panels are clamped together. It is obtained by pushing the elastic waterproof material into the groove through the gap at the end, so it can be installed without using parts such as bolts and nuts or special tools.

The floor panels used in this invention include FRP,
Synthetic resins such as hard vinyl chloride and ABS, and inorganic hardened materials such as asbestos cement can also be used, but especially
FRP is suitable because it is easy to mold and lightweight.

In addition to natural rubber and synthetic rubber, elastic waterproofing materials include, for example, foams 3 to 50 times that of polyethylene, and
A 10 times foamed ethylene polypropylene copolymer or the like is used.

The clamping piece of the fixture is suitably made of a durable metal with strong elastic resilience, and it is preferable that bending guide parts 33, 33 are provided at the tip to facilitate insertion of the support leg.

The cross-sectional shape of the recess formed on the upper outer surface of the side wall may be approximately semicircular as shown in FIG. 1, or may be a shape including a straight portion as shown in FIG. 5.

To form the recess, the side walls 13, . . . are curved or bent to form the recesses 12, . . . as shown in FIGS.
As shown in FIGS. 4 and 6, the upper outer surface of the side walls 7, . . . may be hollowed out to form recesses 71, .

As shown in FIGS. 1, 3 to 5, the outer surfaces of the support legs are suspended downward from the recesses 12, lower end portions 14,... The sides may be pressed against each other, and as shown in FIG. 6, both floor panels A and B do not contact each other, and the elastic waterproof material 41 is pressed by the concave surfaces of both floor panels A and B. It may be done as follows. As shown in FIG. 4, the support legs 83, 83 may be provided with the same width from the bottom of the side walls 8, 8.

FIG. 7 shows an embodiment in which floor panels A, B, and C are joined by the joints of the floor panels of the present invention shown in FIG. 102 is the pedestal that supports the pedestal 1.
01, 101, . . . are the subfloors on which they are placed.

Furthermore, if notches 84, 84 are provided on the outer surface of the lower part of the support leg as shown in FIG. 84, the effect of locking and holding the support leg is even greater. In addition, as shown in FIG.
4, the clamping pieces 32, 32 press the upper portions of the bulging parts 64, 64, so that the effect of clamping the support legs becomes even greater.

(Effect of the invention) At the joint of the floor panel of the present invention, the elastic waterproofing material is compressed and filled in the groove formed by the recess of the two floor panels, so there is a gap between the inner surface of the groove and the elastic waterproofing material. There are no gaps, making it completely waterproof, and the elastic waterproof material will not leak out.

In addition, the support legs of the two floor panels are strongly pressed together between the two clamping pieces with strong elastic restoring force, which are provided facing each other toward the center of the board. Without getting out of the gap,
Since it does not separate laterally, waterproofness is always maintained.

Furthermore, during construction, it can be joined simply by pushing the support leg in while pushing apart the space between the two clamping pieces provided on the fixture, so there is no need to use tightening parts such as bolts and nuts or special tools like in the past. Moreover, the construction is extremely simple and easy, as the floor panels can be joined one by one and can be removed and replaced one by one.
