Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a flooring material for the purpose of shock mitigation, and more specifically, it can be used not only indoors in apartment complexes and single-family houses, but also outdoors on herandas, rooftops, waterproof layers, etc. This is a flooring material that can be used to cushion floors from impact.

(Prior Art) Conventionally, there are two types of soundproof floors: a direct bonding method and a floating floor method, and floating floors are further divided into joist floors and flooring with legs.

The direct pasting method has been widely used in recent years due to its advantages such as less floor space, less negative impact on weight impact noise than floating floors, and faster construction, but it also has the following drawbacks:

The total thickness of a direct-laid floor is at most 20 mm, and since the base is a concrete slab, the human weight does not bend and relieve stress, so a floor that exhibits a soundproofing effect has a small area that is not much different from the area of a human foot. Stress must be relaxed by area. As a result, it had the disadvantage of giving the impression that it was too soft for pedestrians.

Also, since the structure generally includes all finishing materials,
In order to be able to freely select the surface material, it is necessary to offer a wide variety of products.

On the other hand, in the case of a floating floor, the amount of deflection of the floor base and the amount of deflection of the finishing material can be deformed as a whole, and the deformation can be done over a wide area, so it has the advantage of not feeling extremely soft when walking. In the case of No. 2, the impact absorption was mainly due to the effect of the elastic support legs alone, and the damping effect of the floor slab was not utilized, so it is difficult to say that a sufficient damping effect was achieved.

(Problems to be Solved by the Invention) The present invention is a flooring material with excellent shock absorption performance, and because it utilizes the vibration damping effect of the floor slab and legs, it has excellent shock absorption performance while walking. There was a demand for flooring materials that would not feel too soft for people, and that would not deform when loaded with heavy objects such as large computers.

(Means for Solving the Problems) The present invention solves the above problems, and consists of a floor slab sandwiched between a damping material and a plate-shaped body, and a height of 5 to 200 [M
IT:'! This flooring material consists of legs made of a layered combination of A-shaped, plate-shaped, or perforated plate-shaped restraining materials and rubber elastic bodies, and both the floor slab and the legs have excellent vibration damping performance and can withstand shocks with little displacement of the floor slab. It is a relaxing flooring material.

(Function) In view of this situation, the present inventors have developed a product with excellent shock absorption performance.
In addition, the walking sensation was too soft when walking, and as a result of intensive efforts to obtain a flooring material that would deform less even when loaded with heavy objects, we developed a flooring slab with damping material sandwiched between plate-like materials. A flooring material with a height of 5 to 200 ribs that is composed of a layered combination of a net, plate, or perforated plate-like restraining material and a rubber elastic material.The damping material is a cross-linked viscoelastic material that reacts at room temperature. This sheet or sponge sheet uses a combination of liquid rubber and a base material that is better than fiber or foam or a laminate of fiber and foam, so it has excellent vibration damping performance (shock absorption performance) as a flooring material and is comfortable for walking. The feeling of walking is too soft, and even when a load of approximately 250 kg is applied to a large computer, the amount of vertical displacement of the flooring including the legs is 0. It has been found that a shock-reducing flooring material having a thickness of 5 cm or less can be obtained, and that the above-mentioned problems can be solved, and the present invention has been brought to full fruition.

Although the structural member of the present invention has a floor slab and a leg part integrated, the shape of the leg part can be used depending on the location and purpose of use.

Furthermore, in the case of small flooring materials, it is also possible to connect the protruding parts with overhaul tape as shown in Fig. 5.

Furthermore, the connection method can be 2i22 or 4 sides of the floor slab.

Furthermore, the method of supporting the legs can be any combination of 2-point, 3-point, and 4-point support. Each configuration will be described in more detail.

The size of the floor slab sandwiched between the damping material and the plate-shaped body is a square floor plate (A) whose l side is 30 to 90 cm;
The vertical displacement of the floor including the legs (B) with a height of 5 to 200 mm is 0 when a load of 250 kg is applied.
Within 5 cm. In the case of small-sized flooring materials, it is also possible to connect the two or four sides of the joint by using the Ohar tape method, since the joint part of the floor slab is two-sided.

Furthermore, the floor slab and the block-like or joist-like legs are integrated in advance, and the legs are a restraining material in the form of a net, plate, or perforated plate made of synthetic resin, metal, or inorganic material. This is an impact-reducing flooring material that combines powdered rubber, powdered foam, and natural rubber polymer foam alone or in combination with a rubber elastic body in a layered manner.

A sand-shaped floor slab with a rectangular side of 30 to 90 cm and consisting of a plate-like body and a damping layer is made of plywood, compressed paper,
Plastic plate, thin metal plate, vibration damping steel plate, particle board, wood chip cement board, Fihar board, valve cement board, wood wool cement board, flexible board, soft flexible board, large flat board, asbestos cement board, asbestos cement perlite board, asbestos Cement calcium silicate boards, plasterboards, inorganic extruded mold boards, etc. can be used as long as they are in the form of a board, regardless of whether or not the surface is decorated or has holes, but they are not suitable for floor structural components. If the purpose is to reduce the total thickness of the plate, a thin plate is desirable.

If these plate-like bodies are used alone, they are in the form of a sandwich with a damping layer, but the damping layer made into a sandwich can be made of powdered lead, PVC sheet, non-inorganic powder-filled rubber sheet, PVC sheet, or asphalt. asphalt plate by adding iron powder, iron oxide powder, steel slab, etc. and kneading it into a plate, liquid rubber that can be crosslinked viscoelastic by room temperature reaction, and fiber or foam or fiber. A sheet using a base material made of a laminate of foam and
6), sponge-like sheets made of rubber, resin, etc.

In the present invention, a spongy sheet made of liquid rubber and fibers, foams or laminates of fibers and foams, or synthetic rubbers or synthetic resins, which can be obtained by the above-mentioned room-temperature reaction to form a crosslinked viscoelastic body, is particularly preferred in the present invention. It will be done.

The legs are made of resin, metal, or inorganic materials, such as mesh, plate, or perforated plate-like restraining materials, as well as powdered rubber, powdered foam, natural rubber,
Although it is prohibited to combine a rubber polymer foam alone or in combination with a rubber elastic body in a layered structure, it is prohibited to use a restraining material in the form of a net, plate, or perforated plate made of resin, metal, or inorganic material. The thickness of the silk thread is usually about 0.5 mm in diameter. 5-4 cross section, circular, oval, polygonal, iron, Al≧, stainless steel, etc. Reticulated bodies,
Examples include plate-shaped bodies made of polyethylene, polypropylene, polyvinyl chloride, iron, aluminum, stainless steel, ceramics, etc., and perforated plates made of the above materials.

Examples and comparative examples shown in Tables 1 and 2 show examples of cross-sectional views of the floor slab and leg structure of the present invention.

Embodiment 1 is an example in which the floor slab is a rubber sheet restrained by a damping steel plate and a control panel, and the legs are a laminate of a vibration damping sheet and a steel plate. The walking feel and floor impact sound level are also good.

Example 2 has the same structure as Example 1, with each side having a length of 30 squares, and has good walking feel and floor impact sound level.

Example 3 has the same structure as Example 1, and the length of one side is 90 cm.
It is m square, and has a good walking feel and floor impact noise level.

In Example 4, the floor slab is a vibration damping sheet.
The legs are sandwiched with perforated plywood, damping sheet and foam sheet, and the height of the legs is 5.
It has a good walking feel and floor impact sound level.

In Example 5, the floor slab was made by sandwiching a sponge sheet with plywood and particle board, and the legs were made of 5 layers of 175 mm nylon support legs, a damping sheet, and a steel plate, and the length of the legs was 200 mm. The walking feel and floor impact noise level are also good.

Comparative Example 1 has the same structure as Example 1, but the length of one side is 25.
cm. Although the walking feel and floor impact sound level are excellent, there are some problems with workability because they are small.

Comparative Example 2 has the same structure as Example 1, but the length of one side is 95.
cm. The walking feel and floor impact sound level are good, but workability is poor due to the heavy weight.

In Comparative Example 3, the floor slab was the same as in Example 1, and the legs were made of powdered rubber moldings and had a height of 4 m. Workability and walking feel are good, but heavy floor impact sound level is poor.

In Comparative Example 4, the floor slab was the same as in Example 1, and the legs were support legs, 6 nylon 180 mm rubber single body 25 cm, and the height of the legs was 20 mm.
It is 5m+n, and there are problems with the weight, floor impact sound level, and walking feel.

(Effects of the Invention) Since each side of the square is 30 cm to 90 cm and is a sandwich-type floor slab consisting of a plate-shaped body and a damping layer, it is possible to freely select a finishing material of your choice.

In addition, since the floor slab is rectangular with a side measuring 30 to 90 cm, on-site work is easy, layout can be done with a high degree of freedom, and rational design is possible. One side of the rectangle is 30c
If it is less than m, a large number of floor slabs will be required, which increases the price per unit and the number of man-hours during construction, which is not preferable.

If one side of the rectangle is 90 cm or more, it is not preferable because the weight of each slab becomes too large and the construction loss rate is high.

The height of the legs is 5 to 200 mm, and the vertical displacement of the floor including the legs is within 5 degrees when a load of 2.50 kg is loaded, so it has good shock absorption and is easy to walk, which is a disadvantage of the direct attachment method. This eliminates the drawback that time is too soft.

When the height of the leg is 5 cm or less, the displacement of the slab is 0. Although it has a small size of 5 meters and has a good walking feeling, the effect of floor impact noise is small, and if the height of the legs is 200 m or more, the room space will be reduced and the amount of displacement will be large at 5 m or more. The disadvantage is that the feeling of walking becomes worse.

The joint of the floor slab is a butting method and further corresponds to the surroundings of the floor slab 2
Since floor slabs can be joined together using overhaul tape at the protruding parts of the sides or four sides, it is possible to eliminate the problem of steps caused by the protrusion of the joint parts and the unevenness of the base, which were the disadvantages of the overlapping joint method, and the problem of uneven groundwork can be solved during construction. It has features such as easy workability.

Furthermore, since the flooring material is made up of an integrated floor slab and block-shaped or joist-shaped legs, construction workability can be significantly improved, and impact performance can be stably ensured.

As described above, by using the present invention, not only is it possible to improve the walking sensation with good shock absorption, but also because the finishing material and the base material can be separated, the surface finish can be freely selected, and the use of the subfloor space can be made more efficient and efficient. Can be used on land.

Furthermore, since it is a dry-placement type, it can be laid out with a high degree of freedom, allowing for rational design, shortening the construction period, and making construction easy.The industrial utility value of the present invention is therefore extremely high.
