Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof floor structure.

[0002]

2. Description of the Related Art Floors such as balconies and terraces that need to prevent rainwater from leaking downstairs are generally formed by laying a dish-shaped waterproof panel made of synthetic resin on a foundation such as joists. ing. As such a waterproof panel, there is a waterproof panel as disclosed in Japanese Utility Model Laid-Open No. 4-69563. That is, as shown in FIG. 3, the waterproof panel 100 is a dish-shaped synthetic resin floor panel 101.
A plywood reinforcing material 102 is bonded and integrated with a general-purpose water-soluble emulsion adhesive on the back surface of the floor panel 101 so that the floor panel 101 will not be broken even when a heavy object is placed thereon.

A waterproof panel using a galvanized steel sheet or the like as the reinforcing material 102 instead of plywood has also been proposed.

[0004]

In the conventional waterproof panel, the reinforcing material 102 is adhered to the back surface of the floor panel 101 via the adhesive as described above. However, plywood or zinc as the reinforcing material 102 is used. The linear expansion coefficient is different between the plated steel sheet and the floor panel 101 made of synthetic resin. Therefore, the floor panel 101 and the reinforcing material 102 may be separated from each other when used (aging).

On the other hand, if a strong adhesive or an elastic adhesive that absorbs the difference in linear expansion is used, the above problem can be solved, but the cost becomes very high. Moreover, when plywood is used as a reinforcing material, corrosion or warpage occurs due to moisture or rainwater, and when galvanized steel plate is used, rust or corrosion occurs due to sulfides, moisture, or rainwater in the atmosphere, and May not function as

In view of such circumstances, it is an object of the present invention to provide a waterproof floor structure which has excellent adhesion between the floor panel and the reinforcing material, excellent corrosion resistance of the reinforcing material, and can be manufactured at low cost.

[0007]

In order to achieve such an object, the waterproof floor structure according to the present invention has a reinforcing material bonded and integrated along the lower surface of a synthetic resin floor panel,
The reinforcing material is a waterproof floor structure received by the foundation of a building, and the reinforcing material is made of synthetic resin.

In the above structure, it is preferable to use an existing synthetic resin deck material as the reinforcing material. Further, it is preferable that the reinforcing material and the floor panel are bonded to each other using an inexpensive known adhesive. Further, the time of adhering the reinforcing material to the floor panel may be performed after fixing the reinforcing material to the foundation material such as joists, or before fixing the reinforcing material to the foundation material.

[0009]

According to the above structure, since the floor panel and the reinforcing material are formed of synthetic resin, the linear expansion coefficient of the floor panel and the reinforcing material are substantially the same, and even if the bonding is performed by an ordinary adhesive, No peeling due to expansion or contraction occurs. Moreover, since the reinforcing material is a synthetic resin, it has excellent water resistance, acid resistance, and sulfidation resistance, and is less likely to deteriorate or corrode.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing the embodiments thereof. FIG. 1 shows a first embodiment of a waterproof floor structure according to the present invention. As shown in the figure, this waterproof floor structure has a dish-shaped synthetic resin floor panel 1
Is placed on the upper surface of the deck materials 2, 2, 2 having the hollow portion 21, and the deck materials 2, 2, 2 are bonded via an adhesive.
It is adhesively integrated with 2.

The deck material 2 is supported and fixed to the joist 3 serving as a base material, and the engaging projection 22 provided on one side engages with the engaging groove 23 of the adjacent deck material 2. There is. According to the above waterproof floor structure, since the floor panel 1 and the deck material 2 as the reinforcing material are formed of synthetic resin,
There is almost no difference in linear expansion coefficient. That is, thermal stress does not occur due to temperature changes, and peeling does not occur even if the floor panel 1 and the deck material 2 are bonded using an inexpensive general-purpose adhesive.

Further, since the deck member 2 is provided with the hollow portion 21, the flexure can be minimized. Furthermore, even if water leaks from the floor panel 1, the water can be stopped and drained by the deck material, and the water does not leak directly under the waterproof floor. Moreover, since the existing deck material 2 can be used, it is inexpensive. FIG. 2 shows a second embodiment of the waterproof floor structure according to the present invention.

As shown in the figure, this waterproof floor structure further includes a dish-like structure on the deck material 4 of the existing deck balcony 5 in which the corrugated deck material (open deck) 4 is integrated on the joist 3. The floor panel 1 made of synthetic resin is placed and integrally bonded to the deck material 4 via an adhesive. According to the above-mentioned waterproof floor structure, a waterproof floor can be obtained by merely placing the floor panel 1 on the deck material 4 of the existing deck balcony 5 and adhering the floor panel 1 together, and the deck material 4 is used as the floor panel. Since it becomes the reinforcing material of No. 1, it is not necessary to separately bond and integrate the reinforcing material to the floor panel 1.

Moreover, since the deck material 4 as the reinforcing material and the floor panel 1 are made of synthetic resin, even if the floor panel 1 and the deck material 4 expand or contract due to temperature changes, the floor expansion is almost the same even if the floor panel 1 and the deck material 4 expand or contract. No thermal stress is generated in the panel 1 and the deck material 4. Therefore, even if the floor panel 1 and the deck material 4 are bonded using an inexpensive general-purpose adhesive, peeling does not occur.

[0015]

Since the waterproof floor structure according to the present invention is constructed as described above, the floor panel and the reinforcing material do not separate due to thermal expansion and contraction even when an inexpensive adhesive is used, and moreover, the reinforcing material. Has excellent corrosion resistance and does not deteriorate or corrode. Therefore, it is possible to provide a waterproof floor which is excellent in durability and inexpensive.
