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 FFI impact sound such as footsteps, and weight impact vibration sound when a child or the like jumps (for example, impact force 3875N, generation 1
m60dB>. Among these, the light ffl impact sound can be easily solved by laying a soft material such as carpet on the floor surface to absorb and soften it.

することはできなかった。There is a floating floor construction method as a measure to reduce this problem, such as glass wool on the concrete floor slab. There is a wet method (1) in which concrete is poured through 11 butts and a dry method (1) in which pre-fabricated panels are poured in two stages. The former wet type 1
In the law, the Marone grade is L-, which is a level that does not bother you in daily life.
Although it is possible to reduce the cost to 50%, it has the drawbacks of a long construction period and difficulty in applying it to the renovation of existing buildings.
The latter dry method 1 is preferable. However, in the dry method 1 method, for example, on the above-mentioned 1501-thick floor slab, a density of 96h
/+♂, even if glass wool with a thickness of 4Qmm is placed and a concrete panel with a thickness of 5Qmm is placed directly on top of it, the union rating will only be -55, which is a little worrisome, and the noise from daily life will be reduced. It's at a level that doesn't bother me, less than 150,
Preferably, it was not possible to achieve an almost inaudible level of Shi-45.

るという欠点がある。(Problem to be Solved by the Invention) However, in order to achieve the above-mentioned desired noise level using the dry floating floor construction method, it is necessary to further increase the thickness and weight of the floating floor layer, which increases the floor volume. Particularly in high-rise buildings, this method is disadvantageous in terms of structural design and also has the drawback of deteriorating construction efficiency.

が減少するので初期発生音が減じられる。(Function) With the above-mentioned configuration, the impact-absorbing panel of the present invention can be used, for example, when placed on a buffer layer such as glass wool, and at the moment impact energy is applied to the panel surface, the entire panel absorbs the impact energy. The panel tries to deform as it tries to move in the direction of the motion. However, since the irregular high-density elongated material supported in the hollow part of the hollow panel body through the elastic body can move through the elastic body, it tries to stay in place due to inertia and causes other deformation. occurs. At that time, since at least a portion of the irregularly shaped and dense long material is formed in an irregular shape in the longitudinal direction, it is more easily deformed due to inertia than a straight material, and the impact energy is transferred within the panel body. Absorbed. As a result, the amount of displacement of the panel body itself in the excitation direction becomes smaller, and the transmission of vibration to the lower surface is reduced, so that the initial generated sound is reduced.

振動音を低減することができることになる。The degree of vibration absorption and vibration damping in the above-mentioned initial stage varies depending on the difference in vibration frequency between the hollow panel body and the irregularly shaped high-density long material, so the support spacing of the long material and its rigidity should be selected appropriately. As a result, the IiT function effectively absorbs vibrations in a predetermined frequency range, and for example, it is possible to reduce the above-mentioned strain impact vibration noise.

軽量化にも寄与できることになる。In addition, since the structure is mainly made of hollow panels and combined with irregularly shaped high-density long materials, the weight of the panels is reduced.
Handling efficiency 1 Not only will the workability be improved, but it will also contribute to reducing the weight of high-rise buildings.

造が構成される。FIGS. 1 and 2 show a shock absorbing panel A+ according to a first embodiment of the present invention, and the panel A1 is used as a vibration-proof flooring material, for example, glass wool layered on a subfloor made of concrete slab or the like. The revised shock absorbing panels A+, A+... are connected and stretched on the tl shock material,

。In addition, the irregularly shaped high-density long material 3 is made by partially providing a lumpy part such as the above-mentioned spherical irregularly-shaped part 3a on a conventional metal round bar or strip-shaped body as described above, and then it is made by inertia. In addition to other metals, it may be made of a resin body mixed with unevenly distributed metal powder such as lead or mineral powder, or a resin body with a metal lump attached to a resin rod. Further, it is preferable that the specific gravity is 2° or more. Furthermore, although the long material 3 is disposed continuously or discontinuously along the hollow part 2, it is better to make it a continuous body because the vibrations peculiar to the long material, that is, the string vibrations, are suppressed, and f in the longitudinal direction and lateral direction of the long material 3
Since the impact energy is dispersed by J vibration 1 FII L, it is preferable that the photographing of panel Δ1 can be more effectively attenuated.

好ましい。Further, the elastic body 4 is made of an elastic material such as rubber or urethane, and can be easily deformed in order to support the irregularly shaped high-density elongated material 3 so as to vibrate due to inertia.
As shown in the figure, the long material 3 is partially supported by a pond, a hollow part 2
The elongated material 3 is filled and fixed inside the filled elastic body 4.
However, it is preferable to partially support the high-density long material 3 at predetermined intervals as described above because the high-density long material 3 is held in the air and becomes free, making it easier to photograph. .

ことになり、良好な吸振作用が得られる。Therefore, the shock absorbing panel A1 configured in this way
At the moment when the impact energy is applied to its surface, the entire panel AI tries to move in the direction in which the impact energy was applied, and the panel 1 itself also deforms and tries to take a picture. However, in this shock absorbing panel A1, is there an abnormal shape inside the hollow part 2 of the hollow panel body 1? Since the X-density long material 3 is supported via the elastic body 4 and is movable,
The elongated material 3 tries to stay in place due to inertia and undergoes another deformation. In this case, since the deformed high-density elongated material 3 has deformed portions 3a partially formed, the vibratory deformation due to the inertia is more easily carried out by the deformed portions 3a compared to a straight material. As a result, the ffi impact energy is significantly dissipated within the panel AI. the result,
The amount of displacement of panel A+ in the excitation direction is reduced, the transmission of imaging to the lower surface is suppressed, and the initial t111 generated sound is reduced. Furthermore, while the above-mentioned panel A1 is making one movement, the hollow panel 1 and the high-density long material 3 move at completely different natural frequencies, which are canceled out and attenuated within the panel Ai itself. Therefore, the vibration is small and shortened, and the transmission of the image to the floor slab through the glass wool can be suppressed. 1q, in the above embodiment, the irregularly shaped spy long material 3 is partially supported by the elastic body 4 and held in the air, so that the long material 3 is more easily vibrated and deformed and is deformed vertically and horizontally. [11], thereby consuming more impact energy, resulting in a good vibration absorption effect.

際の！Ｉ！吊衝撃振動等の。Moreover, since the irregularly shaped high-density elongated material 3 is supported in the hollow part 2 of the hollow panel body 1 via the elastic body 4, the elastic body The system of irregularly shaped high-density long material 3 including 4 constitutes a sub-vibration system and acts as a dynamic vibration absorber, and both vibrate at completely different natural frequencies, so that the initial It is possible to absorb vibrations and quickly attenuate imaging. In other words, the absorption and attenuation of the imaging of this -panel A+ changes depending on the difference in the natural frequency between the hollow panel 1 and the long material 3, so the distance between the supports of the long material 3 by the elastic body 4 is By appropriately selecting the rigidity, Φfi, etc. of the long body 3, it is possible to absorb vibrations in the predetermined frequency aA range, and therefore, it is possible to absorb the vibrations of the floor impact vibration 1FJJ sound when a child or the like jumps! I! Hanging impact vibration, etc.
従来は防振が困難されていた６３〜２５０Ｈｚの低音域

ある。In addition, the irregularly shaped high-density elongated body 3 in each hollow part 2 of the hollow panel body 1 may have different rigidity or weight, or
High-density elongated materials 3 having different imaging systems are disposed in one panel A1 by intermingling irregularly shaped high-density elongated materials 3 with different rigidities and placed horizontally in one hollow part 2. Therefore, it is also possible to absorb vibrations of multiple frequencies at the same time.
