Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel used for forming a floor such as a balcony or a terrace.

[0002]

2. Description of the Related Art Floors such as balconies and terraces are generally
It is formed by laying floor panels and deck materials made of synthetic resin on foundations such as joists. In particular, when a room or the like is provided below the balcony, a vacuum-formed dish-shaped floor panel is used so that rainwater or the like that has fallen on the balcony does not leak downstairs.

As such a floor panel, an actual flat panel 4-6
There is a floor panel as disclosed in Japanese Patent No. 9563. In this floor panel, plywood is bonded and integrated as a reinforcing material to the back surface of a panel body made of synthetic resin so that the floor panel will not be broken even when a heavy object is placed thereon.

[0004]

However, the above floor panel has the following problems. That is, when this floor panel is installed as a floor of a balcony, the floor panel is heated by being exposed to direct sunlight, but since the thermal expansion coefficient of the panel body and the reinforcing material are different, a force parallel to the bonding surface, that is, There is a problem that shearing force is generated, the adhesion is released, the panel body and the reinforcing material are separated, and the panel body is deformed by thermal stress.

On the other hand, in the floor panels disclosed in Japanese Utility Model Publication No. 4-28355 and Japanese Utility Model Publication No. 4-48341, a foam material is attached to the back surface of the panel body. In order to prevent the peeling due to the shearing force as described above, the thickness of the foam material layer must be 3 mm or more. Furthermore, in order to prevent deformation of the panel body due to thermal stress in a floor panel having a longitudinal width of 3 m and a lateral width of about 1 m, the foam layer has a thickness of 10 mm or more and a Young's modulus of 10 kgf / mm ² Must be: However, if the thickness of the foam material layer is too thick, the floor panel feels soft and the functionality of the floor panel becomes problematic.

In view of such circumstances, it is an object of the present invention to provide a floor panel which has a good bondability between the panel body and the reinforcing material and can sufficiently exhibit the original function of the floor panel.

[0007]

In order to achieve such an object, a floor panel according to the present invention is provided with a corrugated reinforcing member made of a rigid material and having a substantially corrugated cross section and a flat top of the corrugated member. , A cushioning member that is arranged so that the top portion is substantially in contact with the back surface of the panel body and that is deformable with respect to a force parallel to the back surface of the panel body, is formed in the gap between the corrugated reinforcing member and the panel body. At least the inside of the wave trough is filled, and the cushioning material and at least the back surface of the panel body and the wave bottom are bonded and integrated.

In the above structure, the material of the panel body is not particularly limited, but hard vinyl chloride resin, AB
Examples include S resin and FRP. In addition, the corrugated reinforcement is
It is preferably formed of a metal material such as iron or aluminum. The cushioning material is not particularly limited as long as it is a material that can be deformed by a predetermined shearing force, and examples thereof include urethane resin foam, ethylene propylene foam rubber, ethylene butadiene rubber, chloroprene rubber, acrylic resin foam and felt. Is mentioned.

The method of filling the cushioning material is not particularly limited. For example, a foamed resin is injected between the wave troughs and the back surface of the panel body with the corrugated reinforcing material along the back surface of the panel body. Then, there is a method of foaming inside or a method of inserting a columnar cushioning material into the valley portion and adhering the cushioning material to the back surface of the panel body and the bottom surface of the valley using an adhesive or a double-sided adhesive tape. .

The columnar cushioning material preferably has a Young's modulus gradually increasing from both ends in the longitudinal direction toward the center in the longitudinal direction. By the way, when the Young's modulus at both ends is about 1 kgf / mm ² , the Young's modulus at the center is 1.5 kgf / mm ^2.
mm ² is preferable.

[0011]

According to the above construction, the panel body and the reinforcing member are
It is integrated through a cushioning material, and even if a shearing force parallel to the back surface of the panel body is applied to the joint surface due to the difference in coefficient of thermal expansion between the panel body and the reinforcing material, the cushioning material deforms It won't happen. Further, generation of thermal stress is suppressed as much as possible, and the panel body is not deformed. Moreover, the load applied to the panel body is directly and firmly received by the crests of the reinforcing material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing the embodiments thereof. (Embodiment 1) FIG. 1 shows a first embodiment of a floor panel according to the present invention in cross section. As shown in the figure, the floor panel A includes a panel body 1, a reinforcing material (folding plate) 2, and a cushioning material 3.

As shown in FIG. 2, the panel body 1 is made of polyvinyl chloride resin formed by vacuum forming, and has a drainage groove 12 formed so as to protrude toward the back surface along one longitudinal wall 11. And the width (longitudinal width) of the longitudinal wall 11 is 3
m, width is 1m. As shown in FIG. 3, the reinforcing member 2 is formed by bending an iron plate into a corrugated shape, the wave top 21 is flat, and the ridgeline of the top 21 is substantially parallel to the drain groove 12, and The top surface of the top portion 21 is arranged to be in contact with the back surface 13 of the panel body 1.

The cushioning material 3 is formed of an ethylene propylene rubber continuous foam and has a rectangular shape having a thickness approximately the same as the wave height of the reinforcing material 2, and Young's modulus from both ends toward the central portion in the longitudinal direction. Is gradually increased, and as shown in FIG. 4, the wave troughs 22 are filled. And
Epoxy adhesive (Konishi E
-250) and the upper side surface is adhered to the back surface 13 of the panel body 1 via an adhesive.

That is, the floor panel body 1 and the reinforcing material 2 are integrated via the cushioning material 3. This floor panel A was subjected to a cold heat repetition test at -10 ° C to 80 ° C in a constant humidity atmosphere of 80%, and the state of the joint surface was observed. Further, for comparison, a floor panel in which the top portion 21 of the reinforcing material 2 is directly adhered to the back surface of the panel body 1 by an epoxy adhesive (E-250 manufactured by Konishi Co., Ltd.) without using the cushioning material 3 is subjected to the cold heat repeating test. Then, the state of the joint surface was observed.

In the cold and heat repeated test, a longitudinal width of 3 m,
Floor panel with a short width of 1 m from -10 ℃ to 80 ℃ 30
