Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a floor structure having a soundproof and vibration-

The present invention relates to a floor structure having a soundproof and vibrationproof function, and more particularly, to a floor structure having a soundproof and vibrationproof function, and more particularly, The present invention relates to a bottom structure having a soundproof and vibration-proofing function which is made of a laminated structure and is easy to install and maintain, so as to reduce noise due to the installation of a reinforcement mitigating device, mitigate vibration due to an impact,

Generally, in multi-storey apartment buildings, residential complexes, and multi-family houses, when the residents walk or jump on the floor of the upper floor, the floor vibrates and floor impact noise occurs. Only a small part of the floor impact sound is transmitted to the lower layer as it is through the floor while being attenuated, thereby generating noise.

The floor impact sound as described above is classified into a light impact sound generated by a relatively light and hard impact and a heavy impact sound generated by a relatively heavy and soft impact. In other words, it can be classified into a light impact sound made up of a sound of a high frequency band generated due to the falling of a small object, a heavy impact sound composed of a low frequency band sound caused by the walking of an adult, have. Therefore, a sound absorbing material is installed on a concrete slab in order to attenuate the impact sound during the construction process of recent buildings.

However, the conventional sound absorbing material is a structure that can prevent the transmission of light impact sound, and it is estimated that it is not suitable for the country where heavy impact sound is frequently generated.

Another method is to form a lightweight foamed concrete layer on a concrete slab and then to install a heating pipe and form a finishing mortar layer. However, this method is not effective in reducing noise and vibration due to insufficient sound attenuation as a main purpose of insulation function rather than noise attenuation.

In recent years, various types of insulation materials are generally installed in buildings in consideration of heat insulation through members having low thermal conductivity in addition to sound absorbing materials. In other words, sound absorption facilities and sound insulation facilities are absolutely necessary in the spaces where noise such as the recording room, the theater, and the power plant are generated. In the course of designing and constructing the facilities, various types of sound absorbing materials, sound insulating materials, insulation materials, .

However, as can be seen from the name of each construction material of the conventional sound absorbing material, sound insulating material, and insulation material, it is designed and manufactured to have only excellent performance of sound absorption, sound insulation, heat insulation and impact absorption.

Therefore, in the course of designing and constructing a building, it is urgently required to supply a building member with excellent performance in terms of sound absorption, sound insulation, insulation, and absorption capacity of an external impact while occupying less installation space and less installation space.

The above-mentioned invention means the background art of the technical field to which the present invention belongs, and does not mean the prior art.

As shown in the drawings, the floor structure 10 (hereinafter referred to as a floor structure) having a soundproof and vibrationproof function for a multi-story building according to the present invention mitigates the interlayer noise of the multi-story building, The floor structure 10 includes a floor part 20, an interlayer shock absorbing device 30, a heat insulating material 40, and a finishing material 50 (not shown). The floor structure 10 has a soundproofing and anti- And a reinforcement relaxation device 60.

The bottom layer 20 is a concrete layer formed by pouring concrete into a concrete layer. The bottom layer 20 is formed to form a layer of a multi-layered building, and a heating pipe 21 is embedded therein as shown in FIG.

The interlayer shock absorbing device 30 is disposed at an upper portion of the bottom layer portion 20 to have an adiabatic function to mitigate shocks, reduce noise due to an impact, mitigate transmission of vibration due to shocks and external forces, .

The interlayer shock absorbing device 30 includes a shock absorbing casing 31 disposed on the bottom portion 20 and having a seating groove 311 at an upper portion thereof and a sound absorbing hole 321 disposed in the seating groove 311, And an elastic finishing panel 33 attached to the cushioning casing 31 so as to close the seating groove 311.

The cushioning casing 31 is formed of a synthetic resin material or a metal material and is preferably fixed to the upper portion of the bottom portion 20 by an anchor bolt.

The elastic finishing panel 33 is fixed to the upper portion of the shock absorbing casing 31 by bonding or screwing the upper portion of the shock absorbing casing 31. The elastic finishing panel 33 absorbs noise or impact transmitted from the outside by elasticity, .

The sound absorbing balls 32 disposed in the mounting grooves 311 are partially protruded from the upper portion of the mounting grooves 311 and then pressed against the sound absorbing balls 32 protruding from the elastic finishing panel 33 It is preferable that the contact area between the sound absorbing ball 32 and the elastic finishing panel 33 is enlarged to improve the transmission efficiency of impact and noise by being fixed to the shock absorbing casing 31.

At this time, a metal supporting panel having a plurality of through holes is inserted into the upper part of the elastic finishing panel 33 to fill the through-hole when the elastic finishing panel 33, which is a synthetic resin material having elasticity, is melted, It is preferable to improve the supporting force by the support panel and alleviate the impact transmitted by the elasticity of the elastic finishing panel 33. [

The sound-absorbing ball 32 is made of a synthetic resin material having elasticity so as to buffer shocks caused by vibration or external force. The sound-absorbing hole 321 is formed in the sound-absorbing ball 32 so that noise is introduced into the sound-absorbing hole 321, so that the sound is absorbed and noise can be reduced.

The sound-absorbing ball 32 is formed of a foamed synthetic resin such as foamed polyurethane or a resilient synthetic resin such as rubber.

As shown in FIG. 3, the sound-absorbing hole 321 is formed to have a smaller inner diameter from one end to the other end, so that the sound-absorbing hole 321 collides with the inner wall while sound is introduced into the end of the inner diameter, So that the noise can be reduced as a result.

Also, as shown in FIG. 1, noise is introduced into the space between the sound-absorbing balls 32 accommodated in the shock-absorbing casing 31, so that noise can be reduced again by sound absorption.

4, sound-absorbing fleeces 322 are further formed in the sound-absorbing hole 321 formed in the sound-absorbing ball 32 so that a vibration due to a sound wave or a sound wave collides with the sound-absorbing fleece 322, So that the noise can be reduced again.

Alternatively, as shown in FIG. 5, a sound absorbing hole 321 having a width (diameter) that becomes gradually narrower toward the center of the sound absorbing ball 32 may be formed.

Thus, as the vibration along the sound wave or the sound wave from the surface of the sound-absorbing ball 32 toward the central portion progresses, destructive interference may occur to reduce the noise.

The sound-absorbing fleece 322 is formed of a synthetic fiber material, and can be fixed to the sound-absorbing hole 321 by fusion or adhesion.

Alternatively, the sound-absorbing fleece 322 may be integrally formed with the sound-absorbing ball 32 using a synthetic resin material.

Here, it is preferable that the sound-absorbing fleece 322 is further formed on the outer surface of the sound-absorbing ball 32 in addition to the sound-absorbing hole 321 to absorb the impact and reduce the noise.

That is, by forming a sound-absorbing fleece on the outer surface of the sound-absorbing ball 32, it is possible to buffer the vibration between the sound and the sound of the sound and to cancel out the noise.

For example, the sound-absorbing fleece 322 may be separately manufactured in the same manner as the nonwoven fabric formed with fleece and adhered to a part or all of the inside of the sound-absorbing hole 321 or the outer surface of the sound-absorbing ball 32, 32 may be formed by injection molding in a part or all of the inside of the sound-absorbing hole 321 or the outer surface of the sound-absorbing ball 32 at the time of manufacturing.

As the heat insulating material 40, a nonwoven fabric or a rigid urethane foam is used, and any material may be used as long as the material is kept warm. The heat insulating material 40 is disposed on the upper part of the interlaminaral shock absorbing device 30 and may be attached to the upper part of the elastic finishing panel 33 of the interlaminaral shock absorbing device 30.

The finishing material 50 is made of synthetic wood or a synthetic resin material and is disposed on the heat insulating material 40 or is adhered to the upper part of the heat insulating material 40 to be fixed.

The reinforcement mitigation device 60 is disposed at a lower portion of the bottom portion 20 and re-mitigates noise and vibration transmitted from the upper portion. The reinforcement mitigation device 60 has a buffer absorbing space 64 therein A shock absorbing panel 61 and a sound absorbing tube 61 disposed in the shock absorptive space 64 and having an upper portion fixed to the upper surface of the shock absorbing space 64 and a lower portion welded and fixed to the lower surface of the shock absorbing space 64, (62), and a connection pipe (63) connecting the sound absorbing pipes (62).

The buffer panel 61 is made of a synthetic resin material and fixed to the bottom of the bottom layer portion 20 by an anchor bolt.

That is, vibration and noise due to the impact generated in the upper layer are relaxed again by the buffering and absorbing space of the buffer panel 61, and noise (sound waves) flows into the sound absorption pipe 62 and the connection pipe 63 The sound is absorbed in the process of colliding against the inner wall, thereby reducing the noise.

6 and 7, the shock absorbing casing 31 is further provided with a support buffering means 312, and the support buffering means 312 is installed to connect both inner side surfaces of the buffer casing 31, And an elastic supporting portion 312a which is arranged at a predetermined interval to support the sound absorbing ball 32 and an elastic supporting portion 312b which connects the inner upper surface and the bottom surface of the elastic supporting rod 312a and the buffer casing 31 And an elastic spring 312b for supporting and fixing the elastic support bar 312a. The elastic support part is spaced apart from the elastic support part 312 by a predetermined distance so that the sound-absorbing balls 32 are stacked, And the elastic supports are interconnected by the elastic spring 312b.

The elastic support rod 312a is made of a synthetic resin material having elasticity or a metal material having elasticity and is fitted to the inner side surface of the shock absorbing casing 31 or is screwed and fixed. So that the shock absorbing ball 32 can be supported while supporting the load, and the impact can be buffered.

At this time, the load is again supported by the elastic spring 312b, and the vibration due to the shock can be buffered.

Referring to FIG. 9, the sound absorbing pipe 62 has a hollow structure. The inner diameter of the sound absorbing pipe 62 gradually decreases from the upper portion to the lower portion, so that the sound absorbing pipe 62 collides with the inner diameter of the sound absorbing pipe 62 It gradually decreases and is reduced.
