妨げるものではない。The present invention will be described in detail below. In the present invention, a height-adjustable support with a soundproof leg having a specific nonwoven fabric is used, and after the support with the soundproof leg is placed on the floor base, a floor base material and a floor surface finishing material are laid. It consists of a structure. In the soundproof double floor structure of the present invention, since the floor impact sound can be reduced by the specific support and the floor base material, the floor surface finishing material is conventionally used as a finishing material for improving the lightweight floor impact sound. It is worth noting that even those that have been said to be very difficult to use can be used. For example, a wooden floor material such as a single-layer flooring or a composite flooring, a stone material, an inorganic floor material such as a ceramic tile can be used. Of course, it does not prevent the use of a finishing material such as a carpet, a tatami mat, a cork, a linoleum, etc., which has a light weight floor impact noise improving performance.

The floor base material can be appropriately selected as long as it is on a support placed below the floor base material and has a rigidity enough to support a floor surface finishing material and a load on the floor. However, it is necessary to use a board with high rigidity that does not itself cause extreme vibration due to impact force. For example, when using plywood or particle board,
Those having a thickness of 9 mm or more, preferably 12 mm or more are desirable. Other materials that can be considered as the floor substratum include, for example, MDF, wood cement board, ALC board, calcareous board, cement board, and metal panel.

You can use it if you want. Further, the plate material can be used by enhancing the rigidity by reinforcing the honeycomb material, the frame material, the crosspiece material, or the like. Further, as a method for improving the vibration damping property of the floor base material, a base material to which a vibration damping material such as a rubber sheet or an asphalt sheet is attached may be used.

The support member is made of a highly rigid material (rigid body) at least in the layer to which the support leg is attached. It is essential that at least one layer is a non-woven fabric. If the supporting legs come into contact with a portion other than the rigid body portion to which they are attached, vibrations and sounds from the floor may be transmitted to the floor base without being reduced, in which case the soundproofing effect is lost.

It is preferable to use fibers that are significantly crimped. Fiber with remarkable crimp (crimp type fiber)
Is a latently crimped fiber which is a single fiber obtained by simultaneously spinning two kinds of resins having different thermal properties such as polyester or polypropylene, and the fibers are remarkably crimped by heat treatment. . Generally, a non-woven fabric made of latently crimped fibers and heat-treated to crimp the fibers is put on the market. In the present invention, it is desirable to use a nonwoven fabric containing 40% or more of the fibers. If it is less than 40%, it becomes difficult to obtain the desired soundproofing performance. The non-woven fabric not only has appropriate elasticity to absorb impact vibration, but also absorbs impact by converting impact energy into thermal energy by friction between fibers. The thickness of the layer made of the non-woven fabric is 3 mm or more 5 considering the soundproofing performance and the living performance such as walking feeling.
0 mm or less is desirable, and preferably 5 mm or more and 20 mm or less. If the thickness is less than 3 mm, the desired soundproofing performance cannot be obtained, and if it exceeds 50 mm, the living performance and floor strength will be affected even if the material of the fiber material is taken into consideration. The shape of the non-woven fabric is not particularly limited, starting from flat ones, looped naps like carpets, naps raised one by one, rugged shapes, corrugated shapes A variety of shapes such as a broken one are used.

慮した剛体の選択及び支持体設計が必要である。The rigid body, which is the other component of the support member, supports the floor surface finishing material, the load on the floor and the floor base material laid on the support, and also uniformly distributes the load applied to the nonwoven fabric. Therefore, various materials such as plywood, particle board, and metal plate can be appropriately selected as long as they have a rigidity and a thickness that do not cause local deformation, but even if they have a predetermined rigidity, they affect the floor surface. Anything that breaks due to impact is not appropriate. Further, in the rigid body portion to which the support leg is attached, since the load is concentrated on the support leg portion when the support leg having the height adjusting function is attached to the rigid body,
There is a case that it has strength that can withstand this, and it may not be possible to evenly distribute the load applied to the non-woven fabric due to bending around the supporting legs, so it is necessary to select a rigid body and design the support body in consideration of this point. is necessary.

ある。As a method of providing a height adjusting function, a supporting leg whose height can be adjusted is used, such as a metal leg or a resin leg having a screw structure which is known and marketed, and the supporting leg itself is used. Since it is not necessary to have a vibration damping function, it is not necessary to attach an elastic body such as soft rubber to the lower end, but when the floor is constructed when the support legs and the floor base are in contact when the floor is constructed. In the case where floor noise occurs, a buffer layer may be provided to suppress floor noise. It is also possible to embed the lower ends of the support legs directly in the floor base.

200 mm or less, more preferably 30 mm or more 100
The non-woven fabric layer and the rigid body layer may be laminated at appropriate positions with a thickness of mm or less. The size of the support is determined in consideration of workability during construction, but the width is 30 for the purpose of holding the floor base material.
mm or more and 500 mm or less is desirable, and further 50 mm or more 15
It is preferably 0 mm or less. Moreover, it is desirable to appropriately determine the length direction in consideration of workability at the floor construction site. The strength of the supporting legs for height adjustment, which is attached to the supporting body, and the number and interval of the supporting legs themselves are determined by the balance with the load applied to the entire floor surface.

お、実施例は歩行感についても良好であった。As is clear from these results, the floor impact sound level of the example is significantly lower than that of the comparative example. Further, according to comparison with the reference example, it is understood that it is preferable to use a latently crimped non-woven fabric and to make the thickness of the non-woven fabric layer 3 mm or more in order to reduce the floor impact noise. The examples were also good in walking sensation.

Since a plurality of supports with soundproof legs having a specific non-woven fabric layer and a rigid layer are used, and a floor base material is provided on the floor base via the supports with soundproof legs, sound insulation is maintained while maintaining a good walking feeling. The performance can be significantly improved. In addition, since the floor impact sound can be reduced by such a specific support and floor base material, it is possible to use a material with poor sound insulation performance that could not be used as a floor surface finish material in the past. . Further, by using a highly rigid floor base material to reliably support the load on the floor, the soundproofing performance can be improved without further impairing the feeling of walking. Further, in the double-floor structure of the present invention, the arrangement and height of the support can be appropriately changed according to the situation of the site, and the piping and wiring work can be carried out easily without any hindrance.
