Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the improvement of floor covering materials to be applied to the floors of houses.

(Conventional technology) Normally, the subfloor surfaces of concrete floor slabs and plywood floors in apartment complexes, etc., have unevenness of varying degrees due to unevenness, and it is difficult to install floor finishing materials on these subfloor surfaces. If the floor covering material is flexible, such as carpet, it will absorb the unevenness and cause no problem, but if the floor covering material is made of a highly rigid material such as a wooden floor, cannot absorb unevenness, resulting in steps and unevenness on the finished surface.

For this reason, traditionally, in the case of wooden floor finishing materials,
A number of grooves are carved on the back surface to reduce the rigidity, and a rubber backing material with an uneven surface is compositely bonded to the back surface to make it conform to uneven surfaces.

(Problem to be solved by the invention) However, in this type of wood floor finishing material, a void is formed between the floor base and the floor finishing material due to the grooves or the uneven surface of the rubber backing material, and the space inside this void is Especially when the end surfaces of the floor finishing material are joined together by fitting the male and female seeds, the air in the gap has no place to escape and the floor finish deteriorates. A sealed air layer is formed on the underside of the material.

Therefore, when an impact force is applied to the flooring material, especially when a child jumps or something falls, the air layer is compressed as the flooring material bends and deforms, and the impact force is transferred to the flooring material. There is a problem in that the noise is transmitted to the floor and the subfloor vibrates, causing noise to be transmitted and generated downstairs.

Furthermore, when a double-layered floor structure is used, such as a floating floor or a standing floor, where floor panels are placed on the subfloor with a space between them, air from the above space may enter the bottom surface of the flooring material, causing shocks. There was a problem in that the air pressure on the lower surface of the floor finishing material became high and the floor finishing material itself was susceptible to vibration.

Furthermore, there is another problem in that moisture accumulates in the air sealed in the voids, making the area under the floor damp and reducing the service life of the wood floor finishing material.

The present invention provides a soundproof floor finishing material aimed at eliminating such problems.

(Means for Solving the Problems) In order to achieve the above object, the floor finishing material of the present invention has, as shown in the drawings corresponding to the embodiments, one of the opposing side end surfaces of the floor plate main body 1. A female part 3 consisting of a concave groove is provided, and a male part consisting of a plurality of protruding pieces 2 which can fit into the female part 3 is provided on the other side end surface between the protruding pieces 2. The space portions 4 are provided at appropriate intervals and protrude intermittently, and the lower surface of the floor plate main body 1 is formed with air passages 5 of an appropriate width through which air can flow through a plurality of grooves, etc.
The air passage 5 is characterized in that the end thereof is communicated with the space 4 between the protruding pieces 2.

(Function) When an impact force is applied to the floor finishing material, the floor finishing material instantaneously undergoes elastic compression deformation, and the air in the passage 5 formed on the back side is compressed. It communicates with the surface side via the space 4 between the protruding pieces 2 at the joint between the floor finishing materials, and
Since the length of the protruding piece 2 is formed to be larger than the depth of the groove of the female part 3 to be fitted, the passage 5
The air inside is led to the surface side of the joint of the floor finishing material through the space 4 and flows out to the outside.
The air pressure in the passage 5 does not increase at all, and the impact force transmitted to the subfloor is alleviated, and the vibration of the floor covering material itself is also reduced. Further, since the inside of the passage 5 communicates with the indoor side through the space 4 as described above, moisture does not accumulate.

(Example) To explain the example of the present invention with reference to the drawings, 1
is mainly a rectangular flooring material made of laminated plywood or the like with a decorative layer 1a provided on the surface, and one side end face in the length direction and width direction is provided with spaces 4 formed by notches at predetermined intervals. Projecting pieces 2, 2... with the same projecting length
... 2 is formed, and a female part 3 is formed on the other side end face opposite to the above side end face, and is made of a concave groove that can fit with the protruding pieces 2, 2...
are continuously formed, and furthermore, the protruding length of the protruding piece 2 is formed to be slightly larger than the depth of the concave groove of the female part 3.

Reference numeral 5 denotes air passages formed vertically and horizontally over the entire length and width on the back surface of the floor material main body 1, and grooves of a constant width are carved at predetermined intervals in the length and width directions on the back surface of the floor material main body 1. The opening end 5a of the air passage 5 on the end surface side of the main body 1 of the flooring material
is communicated with at least a part of the space between the protruding pieces 2, 2.

7, 7...7 are convex portions that protrude from the lower surface of the flooring main body 1 by forming channels 5 consisting of concave grooves vertically and horizontally, and the lower surfaces of these convex portions 7 are formed flush with each other. There is.

Further, as shown in FIG. 5, the lower surface of the protruding piece 2 is formed with a thin part 7b formed by a notch 7c along the opening end 5a of the passage 5. As shown in FIG. 4, when the floor finishing materials A and A are connected to each other and installed, the air in the passage 5 also flows from the bottom side of each protruding piece 2, 2 into the joint gap 8 of the floor finishing materials A, A, which are fitted into each other. It is formed so that it can flow to the outside through.

Further, the protruding length of the protruding pieces 2, 2 constituting the male fruit part is formed to be slightly larger than the depth of the concave groove of the female part. When fitted, a joint gap 8 is formed between the floor finishing materials A and A, and air in the passage 5 is guided to the space 4 between the protruding pieces 2 through this joint gap 8. is made to quickly flow out onto the surface side of the floor finishing material A.

In addition, in the above embodiment, the length of the protruding pieces 2, 2 is made larger than the depth of the concave groove of the female part to actively form the joint gap part 8, but the floor finishing material A When using a wooden floorboard with a rough joint end surface, the length of the protruding piece 2 does not necessarily have to be adjusted, since a small gap is formed at the joint where the rough surfaces contact each other and allow air to flow. It is not necessary to make the depth larger than the depth of the groove.

In addition, in order to improve the flow of air to the outside through the joint gap 8 of the floor finishing materials A and A that are fitted together in this way, as shown in FIG. The end face may be formed into an inclined surface 9 that is inclined diagonally upward.

In addition, in the above embodiment, the channel 5 is formed by forming grooves on the lower surface of the floor plate main body 1 of the floor finishing material A.
However, the passage 5 may be formed between adjacent protrusions by integrating protrusions having a certain height and an appropriate shape into the lower surface of the floor finishing material A.

In addition, although the protruding pieces 2, 2, . , a groove 9 is formed on the side end surface of the main body 1 of the floorboard, and protruding pieces 2, 2 made of pieces of wood or the like are formed in the groove 9.
may be configured by fitting and integrating the space portions 4 between the protruding pieces 2, 2.

The floor finishing material A configured in this way is laid on a floor base 10 such as a concrete slab or a floating floor,
Construction is carried out by nailing or gluing using a normal construction method while fitting the male part and female part 3 of the protruding pieces 2, 2 of the adjacent floor finishing materials A, A into each other.

After construction, when an impact force is applied to the flooring material A, the flooring material A undergoes instantaneous elastic compression deformation, and the air in the passage 5 formed on the back surface is compressed. The fluid flows from the open end 5a of the passage 5 on the end surface side of the floor covering material A to the space 4 between the protruding pieces 2, 2, and further to the outside through the joint gap 8 of the floor covering materials A, A fitted together. It flows out instantly, eliminates the increase in air pressure in the passageway 5, and reduces the impact sound transmitted to the flooring, reducing impact noise by about 2 dB compared to conventional floor finishing materials that do not have air flow areas. can be achieved.

In addition, since the lower surface of the floor finishing material A is connected to the indoor side through the space 4 from the passage 5 provided on the lower surface, good air circulation is achieved and moisture does not accumulate. do not have.

(Effects of the invention) As described above, according to the floor finishing material of the present invention, the female part 3 consisting of a groove is provided on one side of the opposing side end surfaces of the floorboard main body 1, and the female part 3 is provided on the other side. The end face has a plurality of protruding pieces 2 that can fit into the female part 3.
A male part consisting of a male part is provided intermittently in a protruding manner with a space 4 at an appropriate interval between the protruding pieces 2, 2,
In addition, an air passage 5 having an appropriate width through which air can flow is formed by a plurality of grooves on the lower surface of the floor plate main body 1, and the end of this air passage 5 is communicated with the space 4 between the protruding pieces 2. Therefore, when an impact force is applied to the floor finishing material A, the air between the floor finishing material A and the flooring material is compressed and flows, and flows from the space 4 between the protruding pieces 2 and 2 of the male part into the room. Since the air pressure inside the lower surface passage 5 of the floor finishing material A does not flow out to the inside and increase, the impact force transmitted to the floor substrate side can be alleviated and the generation of impact noise can be suppressed.

In addition, since the lower surface side of the floor finishing material A communicates with the indoor side from the passage 5 through the space 4 between the protruding pieces 2, 2, the passage The air inside the room flows toward the indoor side, and therefore, the lower surface of the floor covering material A can be kept in an appropriately dry state without being trapped with moisture.

Further, according to the floor finishing material of the present invention, it is possible to perform underfloor wiring by utilizing the space of the passage 5 provided on the underside of the floor finishing material, thereby simplifying the wiring work.
