Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a flooring material that absorbs vibrations caused by impact on the floor, and has excellent soundproofing properties and workability.

Conventional technology There has been an increasing demand for soundproofing from nearby noise, especially floor impact noise in apartment complexes, and sound transmitted through the floor.Recently, there has been a rise in the demand for soundproofing against floor impact noise and sound transmitted through the floor in apartment complexes.Recently, so-called floating floor construction methods, such as wet construction methods in which a glass wool layer is installed in the floor slabs of concrete buildings, have been developed. , Dry construction methods such as laying boards with anti-vibration rubber feet on floor slabs have been used in apartment complexes, etc., and have achieved a certain improvement effect. Moreover, even in wooden and prefabricated single-family houses, appropriate soundproofing measures against floor impact noise are not implemented due to the difficulty of construction due to the complexity of the floor structure.
In order to solve this problem, the applicant previously filed Utility Application No. 58-107238 (Utility Model Application No. 60-15539) for "floor members" and installed them between the floorboards and the floor surface board using the so-called floating floor construction method. proposed a floor material with comprehensively improved soundproofing performance, with the main purpose of preventing the transmission of floor impact sound.

Problems to be Solved by the Invention The above-mentioned flooring material is one in which the flooring material is spread over the floor without any gaps during construction, and is intended to sufficiently absorb impact sound and maintain the vibration damping effect of the floor. It would be even more convenient if the laying process could be simplified in this way. In addition, in order to exert a damping effect on floor impact noise, it is not necessarily necessary to lay it all over the floor, but to focus on areas where impact is likely to occur and generate impact noise. It has been found that even when installed, the desired vibration damping and soundproofing effects can be achieved. However, when such a floor member is partially laid, there are problems in construction, such as the position of the floor member shifting even if the floor member is positioned. The present invention provides a flooring material with excellent workability and effective vibration damping and soundproofing properties.

Means for Solving the Problems The vibration-damping and sound-insulating flooring material according to the present invention has a frame made of an elastic material filled with a fibrous sound-absorbing material or a polymeric foam sound-absorbing material, but with rubber or synthetic resin on both upper and lower surfaces. It is possible to create multiple floor members made of laminated soft surface materials made of aluminum, with the diameter of the maximum circle enclosed in the frame being 5 to 150 cm, and the width of the frame between the inner and outer walls of the frame being 2 to 50 mm. The device is characterized in that it is fixedly attached to the flexible support by a fixing means provided on the flexible support.

One embodiment of the vibration-damping and sound-insulating flooring material according to the present invention will be explained based on the drawings. Fig. 1A is a plan view, and Fig.
2 shows a cross-sectional view, in which fixing means 2 are provided in a grid pattern in a flexible support 1 with cutouts corresponding to the size of the floor member 3, and the floor member 3 is fitted into the fixing means. In this embodiment, the flexible support 1 is a soft synthetic resin sheet reinforced with a woven fabric, with fixing holes, which are rectangular fixing means, corresponding to the shape of the floor member, cut out in a rectangular lattice shape. A rectangular floor member fits into the
The fitting portion is fixed with adhesive. Note that it is not necessary to use an adhesive and it is also possible to simply fit it. In addition to the above-mentioned synthetic resin sheet, a rubber sheet or the like may be used as the flexible support.

Further, for example, ropes made of synthetic fibers or the like may be strung in criss-cross fashion at appropriate intervals in a lattice-like manner depending on the size of the floor member. On the other hand, the fixing hole can be selected to have an appropriate shape other than the rectangle described above, such as a triangle, a rhombus, or a regular hexagon. In this case, it may be possible to fit the floor member without necessarily corresponding to the shape of the floor member. The floor member may be fitted into all of the fixing holes provided in the cutout, and the density of the floor member may be reduced in areas where shocks are likely to occur, for example, the center of the floor, while the floor member may be fitted with high density at the periphery of the floor. etc. may be arranged as appropriate. The fixing holes that do not fit floor members are the first type in order to suppress the vibration of the lower floor plate, reduce radiated sound, and increase the soundproofing effect such as blocking air noise.
As shown in Figure B, it is desirable to seal by pasting a soft sheet 4, preferably a soft sound insulating sheet, such as a soft vinyl chloride resin mixed with heavy metal powder or heavy metal compound powder, etc., and formed into a sheet with increased surface density. .

The fixing means is not limited to the above-mentioned holes, but in the case of a flexible support formed by stretching a rope or the like in a lattice shape, it may be fixed with a fixing device, and a floor member can be used as the fixing device. Any means for tying or anchoring may be used, but for example, strings or the like may be used, or screws may be used to fix the support and the floor member.

Next, for the floor member 3, one example is shown in the plan view of FIG.
As shown in the sectional view, a sound absorbing material 5 selected from a fibrous sound absorbing material such as glass wool or a polymer foam sound absorbing material such as polyurethane foam is obtained by molding an elastic material (rubber in this example) into a rectangular frame. Frame 6
A soft surface material 7 is laminated on both the upper and lower surfaces of the inner surface. In this example, the shape of the floor member is rectangular, but it can be triangular, diamond-shaped, square, hexagonal, circular, etc., as long as it matches the shape and function of the fixing means of the flexible support and can be fitted. However, in this shape, the diameter of the maximum circle enclosed within the frame should be 5 to 50 mm for vibration damping, soundproofing, workability, and manufacturing convenience.
It is necessary to have a range of 150cm. This is because if it is less than 5 cm, it will not only be uneconomical, but also the impact force will not be sufficiently distributed, and if it is more than 150 cm, it will be difficult to manufacture and install. Further, the frame width and thickness between the inner and outer walls of the frame body 6 must be in the range of 2 mm to 50 mm. 2mm
Below 50 mm, the cooperative effect with the sound absorbing material against impact noise and the strength against loads from above are poor.
This is because even if this is done, the strength will not be greatly improved and the cost will increase. Moreover, the height of the frame body is preferably in the range of 10 to 30 mm. This is because if it is less than 10 mm, the vibration damping and sound insulation effects will be poor, and if it is more than 30 mm, the above effects will be poor considering the cost, and problems will arise due to the floating floor structure.

A soft surface material 7 is laminated on both upper and lower surfaces of the frame filled with such a sound absorbing material, and the soft surface material 7 is selected from a rubber sheet, a soft plastic sheet, etc., and is fixed to the surface of the frame. If the soft sound insulating sheet described above is used as the soft sheet, excellent sound insulating properties will be exhibited due to the synergistic effect with the sound absorbing material.

Function In the flooring material according to the present invention, the flooring member 3 fitted or attached to each fixing means of the flexible support
The impact force, vibration, and impact sound applied to the floor member 3 are distributed to the sound absorbing material filled together with the soft surface material of the floor member 3, the frame, and the air enclosed in the frame, and the vibration isolation and damping effects of these materials are This prevents impact forces and sound transmission and damps vibrations. This vibration isolation and damping effect is roughly determined by the spring constant and internal loss of the inner part of the frame, so by appropriately selecting these values, you can prevent the frame from ``sagging'' due to the load inside the frame. The part filled with the sound absorbing material inside the frame sufficiently and sustainably exhibits a buffering effect, performs vibration isolation and damping action that rapidly damps vibrations, and reduces floor impact noise. In addition, by pasting and sealing the areas where the flooring material is not fitted with a soft sheet, especially a soft sound insulating sheet, it works in conjunction with the area where the flooring material is fitted to prevent the transmission of noise in the audible frequency range. ,
It also exhibits excellent soundproofing properties.

In the present invention, the floor member 3 is fitted or attached to the fixing means of the flexible support 1, and can be placed at a desired position without shifting its position.

Effects of the invention The vibration-damping and sound-insulating flooring material according to the invention has the above-described structure, and includes a flooring member fitted or attached to the fixing means of the flexible support and other flooring members closed with a soft sheet. In addition to effectively exhibiting vibration damping and soundproofing effects, each floor member is fixed in position within the support body, so its position will not shift during construction or during long-term use. Since the floor members can be placed mainly in areas where vibrations are applied, there is an advantage that vibrations can be effectively isolated and damped. In addition, if a floor material is fitted or attached in advance, it can be transported, for example, in a roll, using the flexibility of the support, and rolled out at the construction site, allowing the floor material to be laid one by one. It has the advantage of eliminating the lining up process, allowing accurate and easy construction, and greatly reducing construction costs.
