Abstract

PROBLEM TO BE SOLVED: To avoid condensation and to improve durability by holding a board- shaped foaming material in a nearly flat board-shaped panel body made of FRP to form them into a single body. SOLUTION: A panel body 1 is composed of a flat board-shaped part 1a constituting a floor surface part, an engaging piece 1b formed around the part 1a to position and fix the part 1a on a floor crosspiece, and a drainage groove 1c formed on one side of the part 1a, and these members made of FRP are formed into a single body by press molding. In the part 1a, foaming material 2 such as hard foamed urethane is held between a front surface layer 11a and a rear surface layer 12a of FRP so as to make them integral with each other. And a plurality of legs 3 for causing inclination are fixedly attached to the rear surface of the material 2, nearly in parallel with the groove 1c, and each leg 3 is projected to the rear surface side of a floor panel through the layer 12a of FRP. Thus the flat board-shaped part of the panel body is reinforced with foamed material and also heat conduction between the front and rear layers can be restrained so that condensation can be prevented.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a floor panel used as a floor material for balconies, terraces and the like.

[0002]

2. Description of the Related Art As a flooring material for balconies, terraces, balconies, etc., an FRP having a substantially flat plate shape as a whole and, if necessary, integral mounting pieces, drainage grooves, etc.
Floor panels made of aluminum are known (for example, Japanese Utility Model 2-145
No. 05). Such floor panels are usually laid on the lower ground of balconies, terraces, etc. with a slight inclination in a predetermined direction, but the inclination is fixed to the back surface side of the substantially flat panel body. It is provided by a leg for imparting inclination or by interposing a crosspiece for imparting inclination on the base.

Here, in such a floor panel,
Conventionally, in order to reinforce a substantially flat panel body made of FRP to prevent the occurrence of bending or the like, a plywood is often attached to the back surface side of the panel body (the above-mentioned No. 2-14505, No. -32501). In addition, when providing the above-mentioned inclination-providing leg part, the leg part is fixed to the reinforcing plywood.

[0004]

By the way, since this kind of floor panel is laid with the legs, crosspieces, etc. interposed on the base of a balcony or the like as described above, the floor panel rear surface and the base are not separated from each other. A space of about 10 cm is often formed between them. With such a space formed on the back side,
Especially when the airtightness of the space is high, dew condensation is likely to occur when a temperature difference occurs between the front surface side and the back surface side of the floor panel.
In a conventional floor panel in which a reinforcing plywood is attached to the back surface of a FRP panel body, if such dew condensation occurs on the back surface side, the reinforcing plywood may be corroded or the base material may be corroded. Become.

In addition, since the conventional floor panel having the reinforcing plywood attached to the back surface is made of different materials, the difference in the coefficient of thermal expansion between the materials causes the panel body to be used over a long period of time. There is also a problem in terms of durability such as separation from the reinforcing plywood.

The present invention has been made to solve the above problems, and an object thereof is to provide a floor panel which is less likely to cause dew condensation and has excellent durability.

[0007]

A structure for achieving the above object will be described with reference to FIG. 1 showing an embodiment. A floor panel of the present invention is a substantially flat panel body made of FRP. The inside of 1 is characterized in that a plate-shaped foam material 2 is sandwiched and integrated.

Here, it is more preferable to form a plurality of small through holes 21 in the plate-shaped foam material 2 provided inside the panel body in order to improve the peeling resistance to the panel body 1 (FIG. 2). reference).

Further, the floor panel of the present invention comprises a panel body 1
It is possible to adopt a structure in which the leg portion 3 for imparting inclination is fixed to the back surface side of the above. In that case, it is more preferable to form the leg portion 3 with a foam material in terms of improving the dew condensation prevention effect. (See Figure 3).

Examples of the material of the foam material used in the present invention include rigid foam urethane, foam polystyrene, foam phenol resin, foam resin such as urea resin, and
Foam concrete etc. can be mentioned.

<Function> The present invention uses a foam material instead of plywood as a reinforcing material for the panel body, and adopts a structure in which the foam material is sandwiched and integrated inside the panel body to achieve a desired object. Is to achieve.

That is, the foam material has a large heat insulating effect,
By sandwiching such a foamed material 2 inside the panel body 1, even if there is a difference in atmospheric temperature between the front surface side and the back surface side of the floor panel, heat conduction in the floor panel is suppressed, and as a result, the panel is reduced. The front surface and the back surface of the main body 1 maintain a temperature close to the ambient temperature on each side, and dew condensation is less likely to occur.

Further, since the foamed material 2 is sandwiched inside the panel main body 1 and integrated with each other, there is a possibility that peeling may occur at the interface between the two as compared with the structure in which plywood is attached to one surface. Less and improved durability.

When the foam material 2 is made of a suitable foam resin, the difference in the coefficient of thermal expansion from the FRP panel body 1 is smaller than that when plywood is used, and peeling occurs more. Further, even when a foam material of any material is used, by forming a plurality of small through holes 21 in the foam material 2, the adhesion effect to the panel body 1 is improved by the anchor effect, and peeling is more likely to occur. Less likely to occur.

[0015]

FIG. 1 is a vertical sectional view showing the structure of a preferred embodiment of the present invention. The panel body 1 is formed around a flat plate-shaped portion 1a that constitutes a floor surface portion,
It consists of a mounting piece 1b for positioning and fixing on a floor receiving bar provided on the structure of the balcony, etc., and a drainage groove 1c formed on one side of the flat plate-shaped portion 1a, which are integrated by press-molding the FRP. Has been formed.

Inside the flat plate-shaped portion 1a of the panel body 1,
A plate-shaped foam material 2 having an area substantially over the entire area of the flat plate portion 1a is arranged. That is, the panel body 1
The flat plate-shaped portion 1a of 3 has a three-layer structure in fact, and the foam material 2 is sandwiched between the front layer 11a and the back layer 12a made of FRP, and these are integrated with each other. There is. The material of the foam material 2 is foam resin such as hard foam urethane in this embodiment.

Further, in this embodiment, a plurality of leg portions 3 for imparting inclination are provided on the back surface side of the foam material 2, and the drain groove 1 is provided.
The leg portions 3 are fixed substantially in parallel with c and penetrate the FRP back surface layer 12a to project to the back surface side of the floor panel.

According to the above embodiment, the panel body 1
The flat plate-shaped portion 1a is reinforced by the plate-shaped foam material 2 inside thereof, and at the same time, due to the heat insulating effect of the foam material 2,
Heat conduction between the front and back of the panel body 1 is suppressed. Therefore, even if there is a temperature difference between the front and back sides of the panel body 1, heat transfer inside the floor panel due to the temperature difference is suppressed, and the front and back sides have temperatures close to the respective ambient temperatures. Condensation is less likely to occur because it is maintained

Further, the foam material 2 as the reinforcing material is FR
Since it is integrally formed in a state that it is sandwiched in the flat plate-shaped portion 1a of the panel body made of P, it can be peeled off even after long-term use as compared with the conventional structure in which one side of the plywood is bonded to the panel body. Further, if the material of the foam material 2 is a resin having a coefficient of thermal expansion close to that of the resin used for the panel body 1, peeling due to the difference in coefficient of thermal expansion is less likely to occur. .

FIG. 2 is a vertical sectional view showing the structure of another embodiment of the present invention. The feature of this embodiment is that a plurality of small through holes 21 are formed in the plate-shaped foam material 2 sandwiched in the panel body 1. Such a small through hole 21
To form the front surface layer 11a and the back surface layer 12
The FRP forming a enters into each through small hole 21, the adhesive strength between the panel body 1 and the foam material 2 is improved by the anchor effect, and the peeling between the panel body 1 and the foam material 2 becomes further difficult to occur. Even if a material having a different thermal expansion coefficient from the FRP panel body 1 such as foamed concrete is selected as the foaming material 2, peeling due to the difference in the thermal expansion coefficient is less likely to occur due to long-term use.

FIG. 3 is a longitudinal sectional view showing the structure of still another embodiment of the present invention. The feature of this embodiment is that the material of the leg portion 3 for imparting inclination, which projects to the rear surface side of the panel body 1, is formed of a foam material such as hard urethane foam. That is, in this example, the leg portion 3 also made of the foam material is fixed to the plate-shaped foam material 2 sandwiched in the panel body 1, or these are integrally formed, and the leg portion 3 is projected. FR the foam material 2 in the state
A structure in which the front surface layer 11a and the back surface layer 12a made of P are sandwiched and the whole is integrated is adopted.

In the floor panel having the structure shown in FIG. 3, since the legs 3 suppress the transmission of the temperature of the base such as the balcony to the floor panel, the temperature on the back surface side of the panel body 1 is the same as that of the surrounding area. It becomes closer to the ambient temperature, and it is possible to more reliably prevent dew condensation on the back surface side.

As described above, the present invention is characterized in that the plate-shaped foam material 2 is sandwiched in the panel body 1 and integrated with each other, but inside the panel body 1, In addition to the foam material 2, other plate-shaped bodies can be sandwiched. Hereinafter, the example is described.

FIG. 4 shows an example in which the plate-shaped foam material 2 and the sound insulating material 40 are sandwiched inside the panel body 1. The foam material 2 and the sound insulating material 40 are in the form of a flat plate of the panel body 1, respectively. Having a spread over the entire part 1a,
These are integrated in a state of being sandwiched by the FRP surface layer 11a and the back surface layer 12a of the flat plate portion 1a. The material of the sound insulating material 40 is a material having a large specific gravity, such as lead.

By adopting the structure shown in FIG. 4,
Even if there is a drastic change in load on the panel body 1,
Sound generated thereby is blocked by the sound insulating material 40, and rattling and squeaking noises generated when walking on the panel body 1 are also blocked by the sound insulating material 40. As a result, it is difficult to transmit the sound to the lower part of the floor panel, and particularly the floor panel. This is effective when there is a living room or the like under the panel laying position, and a floor panel having a sound insulating effect in addition to a heat insulating effect can be obtained. Further, the sound insulating material 40 also functions as a reinforcing material, and a floor panel having higher strength can be obtained.

Further, by adopting the structure in which the foam material 2 is arranged below the sound insulating material 40, the foam material 2 has a sound absorbing effect to some extent, so that the soundproofing effect is further improved. In order to further improve the soundproof effect, a sound absorbing material such as glass wool may be arranged below the sound insulating material 40 and above or below the foam material 2.

Further, if a plurality of small through holes are formed in the sound insulating material 40 sandwiched in the panel body 1 together with the foam material 2, the FR of the surface layer 11a is formed in each through small hole.
P intrudes, the adhesion effect to the panel body 1 is improved due to the anchor effect, and the risk of peeling them off even after long-term use is reduced.

In each of the above embodiments, an example is shown in which the leg portion 3 for imparting the inclination to the floor panel is fixed to the back side of the panel body 1, but the leg portion 3 is not always necessary. If the leg portion 3 is not provided, a crosspiece or the like for imparting an inclination may be separately arranged on the balcony base or the like. In addition, when the leg portion 3 is provided, it is needless to say that the leg portion 3 may be directly fixed to the back surface of the panel body 1 in addition to the structure in which the leg portion 3 is fixed to the foam material 2 as in the previous examples. Is.

[0029]

As described above, according to the present invention, the FRP
Since a plate-shaped foam material is sandwiched and integrated inside the panel body made of steel, heat transfer inside the panel body is blocked, and even if there is a temperature difference between the front and back sides of the panel body. , Condensation does not easily occur on the panel body, and there is no risk of corroding the balcony base. In addition, since the foam material is sandwiched and integrated inside the panel body, compared to a conventional floor panel in which a plywood is bonded to the back side of the panel body, the boundary between different materials is long-term use. The possibility that peeling will occur on the surface is reduced, and if the through small holes are formed in the foam material, peeling will be less likely to occur due to the anchor effect, and a floor panel with high durability can be obtained. Further, since the weight is lighter than the case where plywood is used as the surface reinforcing material of the panel body, a floor panel excellent in workability can be obtained.
