【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view showing a waterproof floor panel 1 according to an embodiment of the present invention, partially broken away. The waterproof floor panel 1 comprises a synthetic resin floor panel body 2 and a synthetic resin reinforcing member 3 joined to the back side of the floor panel body 2. The waterproof floor panel 1 includes a balcony or the like protruding from a house. It is what constitutes.

The floor panel body 2 is, for example, a synthetic resin molded product such as polyvinyl chloride or glass fiber reinforced polyester, and the rainwater that has flowed out is drained in front of the floor panel body 2 on the outdoor side. A drainage groove 4 for forming a drainage groove 4 is formed, a water collecting portion 4a is formed in a part of the drainage groove 4, and a drainage port 4b for connecting a gutter is formed on the bottom surface of the water collecting portion 4a. In addition, a concave groove 4c is formed on the peripheral edge of the floor panel main body 2 excluding the drain groove 4, and a front side surface 5a is formed on the front end edge of the drain groove 4 and a rear side surface 5b is formed on the house side of the concave groove 4c. However, the left and right side surfaces 5c and 5d are erected on the left and right sides, respectively, to maintain the ease of attaching side walls such as balconies.

Expansion / contraction grooves 7 having a substantially U-shaped cross section are formed at predetermined intervals in a direction orthogonal to the length direction, that is, orthogonal to the drain grooves 4. The expansion / contraction absorbing groove 7 is connected from the front side surface 5a to the rear side surface 5b of the drainage groove 4, and the expansion / contraction absorbing groove 7 divides the surface of the waterproof floor panel 1 into a plurality of walking surfaces 6. Since the waterproof floor panel 100 made of vinyl chloride has a width of 900 mm in the length direction and expands or contracts by about 3 mm under a temperature difference of 50 ° C., the waterproof floor panel 1 of the present invention is aesthetically and pedestrian-friendly. In consideration of biting of the toes, as shown in Fig. 3, the width H of each walking surface 6 of the floor panel main body 2 is separated to about 300 to 900 mm by the plurality of expansion and contraction absorption grooves 7 to expand and contract. The absorption groove 7 is a U-shaped groove having a groove width W of about 5 to 20 mm. Further, in the direction orthogonal to the length direction of the waterproof floor panel 1, that is, in the width direction, the expansion width of the balcony or the like is generally 900 mm or less, so that there is no need to provide the expansion and contraction absorbing groove. However, if the width direction is 900 mm or more, it is preferable to provide the expansion / contraction absorbing groove.

The heights of the front side surface 5a, the rear side surface 5b, and the left and right side surfaces 5c, 5d may be the same as or higher than the walking surface 6 of the floor panel body 2. In addition, it is preferable that the surface of each walking surface 6 is appropriately provided with an uneven pattern that also serves as a slip stopper, for example, a stucco pattern or the like, so as to have a slip preventing effect. Furthermore, the floor panel body 2 may have a flat walking surface, and the groove 4c may not be provided on the left and right.

The synthetic resin reinforcing material 3 joined to the back side of each walking surface 6 of the floor panel main body 2 separated by the expansion / contraction absorption groove 7 is separated by the expansion / contraction absorption groove 7 and is similar to the floor panel main body 2. For example, it is molded with a synthetic resin such as polyvinyl chloride or glass fiber reinforced polyester. As shown in FIG. 2, each reinforcing tool body 8 has three vertical ribs 8c, which are a flat surface material 8a on the upper side and a flat back surface material 8b on the back surface, which are provided at regular intervals in the longitudinal direction. A hollow part 8d is formed by connecting the vertical ribs 8c, and a plurality of the reinforcing tool main bodies 8 are arranged side by side and joined to the back side of the walking surface 6.

A reinforcing body 8 having the same size as the back surface may be joined to the back surface side of each walking surface 6. Further, in the embodiment, the hollow portion 8d is formed in the longitudinal direction, but the shape can be changed by an appropriate design such as providing the hollow portion in the width direction or obliquely providing the vertical rib 8c.

Then, a water-soluble emulsion adhesive or the like having no odor and excellent fire resistance is applied between the back surface side of each walking surface 6 of the floor panel main body 2 and the surface material 8 a of the reinforcement main body 8. The waterproof floor panel 1 is formed by joining the two in a non-separable manner.

The waterproof floor panel 1 in which the floor panel main body 2 and the reinforcing member 3 are integrally joined together is provided, for example, as shown in FIG. A floor skeleton is constructed by placing and fixing a plurality of joists 11a, 11b, 11c, which are sequentially set to have an appropriate flow gradient from the indoor side to the outdoor side, at right angles, and each joist 11a, The back surface material 8b of the reinforcement main body 8 of the waterproof floor panel 1 is adhered onto 11b and 11c via an adhesive or a double-sided adhesive tape (not shown), and further, the front side surface 5a and the rear side surface which are erected on the peripheral edge. 5b and the left and right side surfaces 5c and 5d are fixed to, for example, a front wall 12 and a rear wall 13 and a side wall (not shown) such as a balcony via fasteners 14, and a waterproof adhesive tape 15 is attached to ensure watertightness. To prevent water leakage It has become. Further, a drainer 16 is provided on the rear side surface 5b and the left and right side surfaces 5c and 5d, and caulking agent 17 is filled between the rear side surface 5b and the left and right side surfaces 5c and 5d to prevent water from flowing to the surroundings.

In a balcony or the like using the above waterproof floor panel 1 of the present invention, even if the floor panel body 2 thermally contracts, the thermal expansion and contraction is dispersed to the separated walking surfaces 6, and the expansion and absorption grooves 7 The width of the opening of the waterproof floor panel 1 is absorbed and the thermal expansion and contraction of the waterproof floor panel 1 is almost eliminated. Therefore, it becomes difficult for the floor panel main body 2 to warp in the length direction in which the floor panel easily warps. Further, the floor skeleton is not peeled off from the joists 11a, 11b, 11c, the front wall 12 and the like, and the caulking agent is cut off. In particular, if the expansion and contraction absorption grooves 7 are provided at intervals of 300 to 900 mm, the thermal expansion and contraction of the floor panel body 2 can be reliably absorbed by the expansion and contraction absorption grooves 7, and the above problems can be solved more preferably.

Further, since the floor panel body 2 and the reinforcement body 8 are made of synthetic resin, their thermal expansion and contraction rates are substantially the same, so that there is almost no difference in the thermal expansion and contraction of the waterproof floor panel 1 due to temperature changes. It will not occur and the warp of the waterproof floor panel 1 will disappear. .

Therefore, there is no fear of warping due to temperature change, particularly in the length direction, and the waterproof floor panel 1 does not warp due to temperature change regardless of the construction time. Further, it is possible to provide the waterproof floor panel 1 in which the adhesion and the adhesion to the joists, the front wall and the like are retained and fixed for a long period of time, and there is no leakage. In addition, the synthetic resin reinforcement member 3 having the hollow portion 8d can be significantly lightened as compared with the conventional plywood reinforcement member 102, so that it can be easily carried, and thus workability of a balcony or the like can be improved. Become. Furthermore, since the reinforcing material 3 has the vertical ribs 8c, the rigidity is increased and the waterproof floor panel 1 is not bent even when a person rides on it.

In the above embodiment, the waterproof floor panel 1 using one floor panel body 2 is shown. However, it is a connection type using left and right end panel bodies and a plurality of intermediate floor panel bodies, and each floor panel is It may be used as a waterproof floor panel that has expansion and contraction absorption grooves orthogonal to the length direction of the main body.
