Industrial Application Field This invention relates to a wooden soundproofing flooring material that is attached directly to the concrete slab of a high-rise building. More specifically, it is a wooden soundproofing flooring material that is not intended for carpeting, etc., and has been tested using the light weight impact test method (JIS A
The present invention relates to a wooden soundproof flooring material having excellent soundproofing performance that passes L-55 (hereinafter abbreviated as L-55) of the Japanese Standards (1418). BACKGROUND ART Generally known wooden soundproof flooring materials for the purpose of soundproofing housing complexes, etc. include those in which a rubber sheet is laminated on the underside of a wooden flooring material, and those in which a foamed plastic sheet is laminated on the bottom surface of a wooden flooring material. Problems that the invention aims to solve A common drawback of these conventional wood soundproof flooring materials is that in order to exhibit excellent soundproofing performance, the total thickness of the flooring material must be extremely thick compared to ordinary wood flooring materials. It has to be made thicker. That is, L-55
In order to pass the test, a laminated rubber sheet must have a total thickness of approximately 15 mm or more, including the surface material, and a laminated foamed plastic sheet must have a total thickness of approximately 30 mm or more. In order to pass L-55 when the total thickness of the flooring material is less than 15 mm, there is no effective means other than making the concrete slab thicker than usual or placing a carpet or the like on the floor surface. The purpose of this invention is to manufacture a wooden soundproofing material that is directly attached to a regular concrete slab and has excellent soundproofing performance that passes L-55 with a total thickness of less than 15 mm. . Measures to solve the problem As a result of intensive research, the inventors developed a wooden soundproof floor made by laminating an integrated material of synthetic fiber and synthetic resin foam as a base material on the bottom surface of a surface material made of wooden flooring material. By using a sheet-like material made of non-oriented synthetic fibers as a base material, and forming the sheet-like material made of synthetic fibers into a synthetic resin foam by molding etc. It was discovered that L-55 can be passed with a total thickness of less than 15 mm. In this invention, the surface material is what is called a wooden flooring material used in general housing. Usually, a synthetic material is used, in which a decorative material is attached to the surface. In addition to synthetic materials, laminated wood, solid wood, etc. can also be used. The thickness of the surface material is preferably 5.5 mm to 10 mm. If the thickness exceeds 10 mm, the soundproofing performance will decrease. On the edge of the surface material,
Tongue processing is performed for construction. A sheet-like product made of non-oriented synthetic resin is formed by melting the synthetic resin and extruding string-like fibers, which are then fused together using the heat of the fibers. Ru. Alternatively, it may be formed into a sheet shape using a binder. However, in the sheet-like article formed by either method, the fibers must be adhered to each other in a dotted manner. The types of synthetic fibers used to form sheets include polypropylene, polyethylene, acrylic,
Nylon etc. The average fiber thickness is 0.5mm
~1.0mm is desirable. If it is less than 0.5 mm, pressure resistance is poor. If it is 1.0 mm or more, the soundproofing performance will deteriorate. As the synthetic resin foam, those made from polypropylene, polyurethane, neoprene, etc. as raw materials and foamed at an expansion ratio of 20 to 50 times can be used. If it is 20 times or less, the soundproofing performance will decrease, and if it is 50 times or more, the pressure resistance will decrease. The thickness of the base material, which includes a sheet-like material made of non-oriented synthetic fibers, is preferably 8 mm to 14 mm. If the thickness is less than 8 mm, the soundproofing performance will deteriorate. If it is 14 mm or more, the soundproofing performance will be even better, but the walking sensation will be poor and the cost will be undesirable. The thickness of the synthetic fiber sheet included in the base material is suitably 4 mm to 10 mm depending on the thickness of the base material. The spring constant of the base material is preferably 5×10 6 N/
It should be adjusted to about m3 or less. 5×10 6 N/m 3
Above this level, the soundproofing performance deteriorates. Also, the spring constant is 2
The extremely low value of ×10 6 N/m 3 is also a problem in terms of pressure resistance. Any method such as double-sided tape, adhesive material, or adhesive may be used to bond the surface material and the base material. Function The base material of this invention is composed of a sheet-like material made of synthetic fibers molded in a non-oriented manner, and the sheet-like material made of synthetic fibers is contained in the synthetic resin foam by molding, etc. , moderately elastic. Therefore, in the wooden soundproof flooring material of this invention, the base material acts as a buffer material and prevents the transmission of vibration between the flooring material and the concrete slab, so it is preferable to layer a rubber sheet or a foamed plastic sheet as the base material. It is thought to have superior soundproofing performance compared to conventional wood soundproofing flooring materials. Effects of the invention The wooden soundproof flooring material according to this invention has excellent soundproofing performance, passing L-55 with a total thickness of less than 15 mm. If a wooden flooring material with a thickness of 7 mm to 10 mm is used as the surface material, it is possible to manufacture a wooden soundproof flooring material that has a better walking feel and excellent compression resistance. In this case, it is also possible to place heavy items such as a piano. Compared to other wood soundproof flooring materials that pass L-55, it is lighter than one made of laminated rubber sheets and can be made much thinner than one made of laminated foamed plastic sheets. Therefore, it has excellent workability during manufacturing and construction. There are no working environment problems like glass wool or asbestos. Example As a surface material made of wood flooring material, a decorative board with a thickness of 0.5 mm was laminated on a synthetic surface with a thickness of 5.5 mm.
On the underside of this surface material, a sheet-like material made of non-oriented propylene fibers is used as a base material, and a base material made by injecting and foaming polyurethane into this by molding is attached using a synthetic polymer resin adhesive. Laminated and glued. The dimensions of the flooring material were 300 x 900mm, and the edges of the flooring material were serrated. The wooden soundproof flooring material obtained in this way is 150mm thick.
The floor surface is 2500mm x 2500mm on a concrete slab.
A light and heavy floor impact sound level test and a compression resistance test were conducted by combining the tongues and pasting them together so that the size was . Light weight floor impact sound level test is JIS
A method according to A 1418 was used. In the compression resistance test, a floor material with a deflection of less than 1 mm when a load of 30 kg was applied per 30 cm square of flooring material was passed. Next, the surface material thickness was set to 9 mm (using 8.5 mm plywood),
Similar tests were conducted with various changes in the thickness of the base material and the molding method.
