するものである。Detailed Description of the Invention (Industrial Field of Application) The present invention is directed to a floor that reduces the transmission of weight impact vibration noise generated when a child or the like jumps on the floor in a house, especially an apartment complex, etc. It's about structure.
（従来の技術）
近年、集合住宅等における階上からの衝撃振動

容易に解決することができる。(Prior Art) In recent years, impact vibration noise coming from upstairs in apartment complexes has become a major social problem. This impact vibration sound can be roughly divided into light impact vibration sound such as footsteps, and heavy impact vibration sound when a child or the like jumps (for example, impact force 3875N, generated sound 60dB). this house,
Light impact vibration noise can be easily solved by laying soft materials such as carpet or tatami on the floor surface to absorb and reduce it.

数８×106N／m3で騒音レベルＬが50dBとなる。 On the other hand, there is no sufficient solution to the weight impact vibration noise, but known measures to reduce the weight impact noise include increasing the thickness of the floor slab and creating a floating floor structure. In other words, in the former method of increasing the thickness of the floor slab, for example, if the thickness of the floor slab is increased to 300 mm, which is twice the normal thickness, the impact force will be reduced.
3875N, it is possible to reduce the impact sound of 60 dB by about 12 dB, and for reference, the noise level L according to the Architectural Institute of Japan standard is 55 dB. In addition, the latter floating floor construction method uses the upper floating floor layer (concrete thickness 50
mm) and buffer layer (glass wool 96Kg/ m3 , thickness 25~
This is a method of reducing the impact force applied to the concrete slab by 50 mm), and this reduction effect is determined by the weight of the upper floating floor layer and the spring constant of the cushioning material. The smaller the spring constant of the cushioning material, the greater the effect. For reference, when the slab thickness is 150 mm and the spring constant of glass wool is 8 x 10 6 N/m 3 , the noise level L is 50 dB.

ある。(Problem to be Solved by the Invention) However, both of the above-mentioned conventional measures for reducing weight impact vibration noise require increasing the concrete thickness of the floor, which inevitably increases the weight of the floor.
Particularly in high-rise buildings, this method is disadvantageous in terms of structural design and has the drawback of increasing costs considerably.

端部同士が互いに干渉することはない。(Function) With the above configuration, in the present invention, when a weight impact force is applied to the floor, the impact force acts on each cushioning material through the floor finishing material and the rigid plate. Since it is made of a convexly curved leaf spring body, it deforms into a flattened shape so that the height of the convex portion becomes lower in response to the above-mentioned buffering force. At this time, since the lower edge of each cushioning material is placed so that it can slide freely against the flooring, the cushioning material deforms smoothly, and there is an appropriate distance between the side edges of each cushioning material. Therefore, the side edges of the cushioning material do not interfere with each other as the cushioning material deforms.

This means that it is possible to effectively prevent low-frequency vibrations (up to 250 Hz) from permeating to the lower floor.

とができる。 Therefore, in the floor structure with the above configuration,
When a weight impact force is applied to the floor surface, the impact force acts on each cushioning material 2 through the floor finishing material 9 of the floating floor structure and the particle boards 5, 5, .
Each of the cushioning materials 2 is made of a leaf spring body with a convexly curved upper central portion, and its lower edge is placed on the floor base so that it can slide sideways, so the lower edge slides sideways due to the impact force. It moves and easily deforms into a flat shape, and this deformation of each cushioning material 2 weakens the impact force transmitted to the lower floor. Moreover, the leaf spring bodies constituting each of the cushioning materials 2 are composed of a plurality of plate bodies 3, 3,
... are partially laminated and bonded with rubber 4, 4, ... interposed, so that it can withstand light impact force.
Since the rubber 4, 4 deforms and absorbs it, it is possible to absorb impact force that does not deform the entire leaf spring body.
As a result, the propagation of the impact force to the subfloor 1 is reduced, and transmission of weight impact vibration sound can be effectively prevented.

る。 In that case, both lower edges of each cushioning material 2 are placed on the flooring 1 via a resin sheet 10 with low frictional resistance, and the lower edges of each cushioning material 2 are arranged so that the cross section thereof is a curved surface with a waveform. Since the impact force is applied to each cushioning material 2, the lower edge of the cushioning material 2 slides sideways against the flooring 1 in the direction in which the leaf spring body expands, and each cushioning material 2 becomes strong with the flooring 1. Deforms smoothly without creating an arch. Moreover, since there is a distance D of an appropriate size between the side edges of the adjacent cushioning materials 2, 2, the opposing side edges interfere with each other when the cushioning materials 2 are deformed in the flat direction. Therefore, the effect of reducing weight impact vibration due to the deformation of the cushioning material 2 can be reliably obtained.

が生じることもない。 In addition, the cushioning material 2 made of a leaf spring body absorbs weight impact vibrations, so it has a high ability to absorb impact vibrations, and compared to using elastic mats such as glass wool mats, the floor thickness is thinner and the weight is reduced. Moreover, there is no possibility of partial compressive deformation caused by the elastic mat.

Only the rubbers 4, 4, ... interposed between the plate-like bodies 3, 3 of the leaf spring bodies in each cushioning material 2 are compressively deformed, and the rubbers 4, 4, ... are compressively deformed and the floor finishing material 9
By deforming the carpet 8 and the felt 7 in the above, light impact vibrations can be effectively absorbed.

ツク１２を用いてもよい。 It should be noted that the present invention is not limited to the above-mentioned embodiments, but also includes various modifications. For example, in the above embodiment, the cushioning material is formed by laminating and bonding a plurality of plate-like bodies 3, 3, ... whose central portions are curved upward in a convex manner, with rubber 4, 4, ... partially interposed. Although a stacked leaf spring body was used, as shown in FIG. 4, corresponding side ends of a plurality of stacked plate bodies 3, 3, ... are integrally connected by an elastic body 11 such as rubber. A stacked leaf spring body may also be used.
In addition, as shown in FIG. 5, the back surface (lower surface) of each plate-like body 3 may be coated with ferrite, iron powder, sand, rubber, etc., or embossed or grooved, etc. The plate-shaped bodies 3, 3, . . . may be laminated and bonded after the surface is made into an uneven rough surface 3a. In this case, since the frictional force acting between the plate-like bodies 3 and 3 increases when the cushioning material 2 is deformed,
The impact force acting on the floor surface can be absorbed even more effectively by the deformation of each plate-like body 3 and the frictional resistance between the plate-like bodies 3, 3. Also,
In the above embodiment, a plurality of laminated plate bodies 3,
Although rubber 4 is used as the elastic body partially interposed between 3 and 3, foamed plastic 12 may also be used as shown in FIG.

The lower edge of the cushioning material 2 may be formed into a curved surface, or by bending both ends of the lowermost plate member 3 into a curved shape as shown in FIGS. 7 and 8. You can do it like this. Further, instead of laying the resin sheet 10 on the upper surface of the floor subfloor 1 as in the above embodiment, a resin panel 10 is placed corresponding to the lower edge of each cushioning material 2 as shown in FIG.
3 and 13 may be laid.Furthermore, the surface of the floor base 1 itself may be made smooth, or the lower end of the cushioning material 2 may be made of a relatively slippery material. A structure with smooth sliding may be appropriately selected depending on the type of cushioning material 2 and the like.

When an integrated unit consisting of the particle board 5 and the particle board 5 is placed on the subfloor 1 as shown in FIG. The construction of the rigid board and the rigid board can be done at the same time, improving construction efficiency, and the spacing D between the cushioning materials can be reduced by simply arranging them.
can be maintained. Incidentally, at this time, a piece of wood may be provided on the lower surface of the side end of the particle board 5, and a joint portion, such as an actual processing, may be formed on this piece of wood for connection.

得られることが判る。 Now, specifically, the length is 1820 mm, the width is 910 mm, and the thickness is 5.5 mm.
mm Medium specific gravity fiberboard (specific gravity 0.6) is formed into a semi-cylindrical shape with an arrow height of 50 mm in the center using high frequency heating, and 10 of the formed plates are stacked and their side edges are joined with urethane rubber. A cushioning material was prepared using the following method. This cushioning material is laid on a concrete slab, and a concrete floor panel (density 2300
Kg/m 3 , thickness 50mm) to create a floating floor.
In response, the sound insulation performance of L-45 (special grade ) was obtained. In contrast,
For comparison, a conventional floating floor was constructed by placing the above concrete floor panel on the above concrete slab via glass wool cushioning material (density 96 kg/m 3 , thickness 50 mm), and the floor impact sound of this was measured. The result, as shown by the broken line in Figure 12, was the sound insulation performance of L-55 (class 1). Therefore, it can be seen that in the example of the present invention, the sound pressure is lowered by 10 dB than in the conventional example, and an excellent vibration damping effect can be obtained.

供することができる。(Effects of the Invention) As explained above, according to the present invention, a plurality of cushioning materials made of leaf spring bodies are laid on the subfloor of a house, etc., and a floor finishing material is provided thereon via a rigid plate. The weight impact vibration sound (vibration in the low temperature range 63 to 250 Hz) of the floor impact vibration sound is effectively absorbed by the vibration absorption effect caused by the deformation of the above-mentioned cushioning material, so the weight and thickness of the floor can be reduced. The above-mentioned weight impact vibration can be easily and inexpensively damped without increasing the vibration, and it is possible to provide a floor structure particularly suitable for a high-rise building.
