Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to floor finishing materials used on the floors of buildings such as residences, and particularly relates to measures to eliminate the harmful effects of air stagnant on the underside of the floor.

(Prior Art) Conventionally, in buildings such as houses, there has been a problem that moisture tends to accumulate on the underside of floorboards, causing dew condensation, which essentially reduces the durability of the floorboards.

For this reason, it has been proposed to prevent condensation by providing a groove or the like on the back surface of the floor plate and allowing air to flow through the groove to ventilate the lower surface of the floor plate.

(Problem to be solved by the invention) However, since the above-mentioned conventional method is simply a groove etc. provided on the bottom surface of the floorboard, air circulation within the groove is not sufficient, and the air flows into the groove. stay in
There is a problem that moisture cannot escape and the effect of preventing condensation is low. In addition, when walking on the floor surface, the air in the grooves on the lower surface of the floorboard is compressed, causing a so-called drum phenomenon, which generates a loud sound under the floor, which is not desirable in terms of soundproofing.

This invention was developed to solve the above problems, and by opening the air under the floorboards to the floor surface and allowing the air under the floorboards to flow smoothly without stagnation, it is possible to reduce the noise generated when walking. To provide a floor finishing material which can effectively prevent the occurrence of dew condensation on the underside of the floor without causing any problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention communicates a ventilation passage formed by a groove or the like provided on the back surface of the floorboard with the surface of the floorboard through a communication hole, and also connects the communication hole with the surface of the floorboard. The purpose is to close it with a cap that allows air circulation so that it does not interfere with walking.

Specifically, the solution taken by the present invention is to provide a ventilation path made of a groove or the like on the back surface of the floorboard, and to form a communication hole through the floorboard that allows the ventilation path to communicate with the surface of the floorboard. Furthermore, a ventilating cap having an air circulation part made of fine holes, slits, etc. is fitted into the communication hole.

(Function) With the above configuration, in the present invention, the ventilation passage on the back side of the floorboard is open to the floorboard surface through the communication hole, so that the air under the floorboard can smoothly flow through the ventilation passage without stagnation. Since it circulates and flows out onto the surface of the floorboard, the breathability of the underside of the floorboard becomes good, and the occurrence of condensation due to moisture buildup is effectively prevented. Furthermore, when walking on the floorboard surface, the bending deformation of the floorboard compresses the air in the ventilation passages on the backside of the floorboard, but this compressed air is instantly discharged to the floorboard surface through the communication hole, causing a drumming phenomenon. This will not cause noise generation.

Moreover, since the communication hole is closed by the breathable cap to allow air to flow through it, the above-mentioned function is not impaired, and the communication hole opening into the surface of the floorboard does not pose a hindrance to walking.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIGS. 1 and 2 are views of a floor finishing material A according to an embodiment of the present invention, viewed from the front and back sides, respectively. In the figure, reference numeral 1 denotes a wooden floorboard which is the substrate of the floor finishing material A, and a female part 1a is formed at one opposing end of the floorboard 1, and a female part 1a is formed at the other end. A male part 1b that can be fitted is formed.

A ventilation path 2 is provided on the back surface of the floor board 1 to allow air to circulate along the back surface of the floor board 1.
The ventilation passage 2 is constructed of a grid-like groove formed by cutting the back surface of the floor board 1 as shown in FIG. The ventilation path 2 may also be constructed by using the same.

Furthermore, the floorboard 1 has a plurality of communication holes 3, 3, .
are formed to penetrate vertically, and each communication hole 3
A breathable cap 4 having an air circulation portion 4a is removably fitted to the cap. The air permeable cap 4 is made of metal or plastic, and as shown in FIG. 3, a wire mesh body having a large number of meshes is used as the air circulation section 4a, and as shown in FIG. A type having a slit, or a type having a large number of fine holes such as punched holes as shown in FIG. 5 are used.

Here, when a wire mesh body as shown in FIG. 3 is used as the air permeable cap 4, the communicating hole 3 has a stepped structure having a large diameter hole 3a in the upper stage and a small diameter hole 3b in the lower stage as shown in FIG. hole, upper large diameter hole 3
A cap 4 made of a wire mesh body is detachably inserted into and held from above. In this case, a cylinder made of non-woven fabric or the like is integrated into the small diameter hole 3b of the communication hole 3 at the lower part of the cap 4 and is impregnated with a chemical such as a deodorant, an air freshener, an insect repellent, or a moisture absorbing/releasing agent. The body 5 may also be attached. Alternatively, as shown in FIG. 7, a plastic cap 4 may be removably fitted into the communication hole 3 from above using its elasticity. In FIG. 7, reference numeral 6 designates a hollow support bolt which is screwed into and secured to the communication hole 3 from below in order to support the lower part of the above-mentioned fitting type cap 4.

As shown in FIG. 8, the floor finishing material A configured as described above is placed and fixed on the floor sub-material 7, and the adjacent floor finishing material A has a female part 1a and a male part 1b. The floor surface is constructed by sequentially connecting and juxtaposing them by actual joining by fitting them together.

In this case, the floor finishing material A has an air passage 2 on the back surface of the floor board 1, through which air flows along the back surface, and the air passage 2 is connected to the surface (floor surface) of the floor board 1 through the communication hole 3, so that the air under the floor board 1 flows smoothly without stagnating in the air passage 2 and flows out to the surface of the floor board 1, improving the breathability and ventilation of the underside of the floor board 1. As a result, it is possible to effectively prevent condensation caused by moisture building up under the floor board 1. Moreover, since the air passage 2 is connected to the surface of the floor board 1, even if the floor board 1 is bent and deformed when walking on the floor surface, and the air in the air passage 2 is compressed, the compressed air is instantly discharged to the surface of the floor board 1, and there is no sound due to the drumming phenomenon, and there is no problem in soundproofing.

Furthermore, since a ventilating cap 4 having an air circulation portion 4a is fitted into the communicating hole 3 that opens on the surface of the floorboard 1, the upper opening of the communicating hole 3 can be closed without impairing the above-mentioned air permeability. It does not cause any difficulty in walking.

Furthermore, if the cylindrical body 5 impregnated with a chemical such as a deodorant, an insect repellent, or a moisture absorbing/releasing agent is attached to the breathable cap 4 as in the above embodiment, the air flowing through the breathable cap 4 can be protected against air. It exhibits medicinal effects such as deodorizing, insect repelling, and moisture absorbing and releasing properties, and can improve the environment of living spaces. Particularly in this case, it is convenient to make the breathable cap 4 removable so that the medicine can be easily replaced.

In addition, in the construction state as shown in FIG. 8, if a cushioning material is adopted as the flooring material 7, the compressed air in the ventilation path 2 generated when an impact force is applied to the floor finishing material A as described above is transferred to the floorboard 1. In addition to being able to smoothly discharge the air to the surface, the soundproofing performance can be further improved due to the cushioning effect of the cushioning material. In addition, when a heat-generating panel for floor heating is adopted as the floor underlayment 7, the air in the ventilation path 2 is warmed, and this warm air is discharged indoors through the communication hole 3, improving heating efficiency. do.

In Figure 0, a concave-convex sheet 9 made of rubber or foam and having a concave-convex surface consisting of concave portions 9a and convex portions 9b is adhered to the back surface of the floorboard 1 with the concave-convex surface facing the back side, and the concave and convex portions of the concave-convex sheet 9 Air passage 2 by 9a
In this case, there is an advantage that the air in the recess 9a, that is, the air passage 2, can smoothly flow out due to the elastic deformation of the projection 9b.

Moreover, FIG. 11 shows an example in which a floor board and a floor panel are integrated to form a floor finishing material, and the floor panel is a hollow panel 1 having a hollow hole 10a inside.
0 is used, and a floorboard 1 is placed on the surface of the hollow panel 10.

Supports 11 are adhered to the back surface at appropriate intervals, and a ventilation passage 2 communicating with the communication hole 3 is formed between the supports 11, and an opening on the upper surface of the communication hole 3 is provided with air permeability. A cap 4 is fitted into the cap. In this case, the compressed air in the ventilation passage 2 that is generated due to the bending deformation of the floor finishing material when floor impact force is applied is allowed to escape above the floor surface through the communication hole 3 and also laterally through the hollow hole 10a. As a result, the compressed air can be discharged even more smoothly, and the dew condensation prevention effect and soundproofing performance can be improved.

(Effects of the Invention) As explained above, according to the floor finishing material of the present invention, the ventilation passage on the back side of the floorboard is communicated with the floorboard surface through the communication hole, and the breathable cap is fitted into the communication hole.
