Description

Panel for preventing impact vibration and sound between floor in apartment house}

The present invention relates to a noise preventing structure of a multi-family house, and more particularly, to an impact vibration absorbing panel between floors of a multi-family house that can significantly reduce or block not only the light impact sound generated in the multi-unit house but also the heavy impact sound.

As shown in FIG. 1, the floor noise preventing structure 10 of a multi-family house is constructed on a floor slab 1 constituting a floor of a multi-family house, and the upper side of the floor slab 1 to perform an insulation function. Foamed concrete (2), styrofoam (3) that is interposed between the floor slab (1) and the foamed concrete (2) to perform the sound absorbing material to absorb the interlayer noise, and plastered above the foamed concrete (2) It consists of a backing finish and adhesive mortar (4).

The interlayer noise prevention structure 10 of this configuration is primarily absorbed by the impact sound generated in the upper surface material (7), and then transmitted downward, finishing and adhesive mortar (4), foam concrete (2), styrofoam (3) In order to pass through the floor slab 1 sequentially, some of the material is absorbed by the materials to prevent the noise from being transferred to the lower layer. Here, reference numeral 6, which is not described, denotes a wall slab.

Recently, the floor noise prevention structure (10) of apartments such as apartments, villas, and townhouses has emerged as an essential element in the pleasant living environment of residents, and the noise generated from the apartment houses is the sound of running, stairs, footsteps, and front doors. The influence of solid sounds, such as open and close sounds is largely shown.

In particular, floor impact noises running or walking upstairs appear to be the most nervous in the bottom. These floor impact sounds can be classified into two types: lightweight impact sounds such as walking on a floor or dragging a chair, and heavy impact sounds generated when children jump on the floor.

These lightweight impact sounds can be significantly improved by the treatment of the surface material 7 on the finishing and adhesive mortar 4, the double ceiling structure, etc., since the impact force is small. That is, in the case of the surface material 7, the use of a soft elastic material such as carpet can reduce the impact light weight, but recently, due to problems such as cleaning, insects, floor boards, flooring (flooring), etc. Is also a problem.

In this case, a shock absorbing material such as rubber, vinyl, waste tire, styrofoam (3) can be put between the floor slab 1 and the foamed concrete 2 to solve the problem of light impact sound to some extent. It is insufficient to process only, and above all, it is necessary to increase the thickness of the floor slab 1 by constructing it to 200 mm or more.

In this case, however, a lot of material is put into the floor slab, especially due to the increased load, which is quite economical. It is difficult to adopt it as a realistic countermeasure because it requires a number of non-technical requirements.

In addition, foam concrete, which is constructed for insulation and noise prevention, is a product that is cured by mixing water and air in cement and is excellent in sound insulation and sound insulation, but it does not attenuate shock vibration due to the fine structure and high strength of cement. There was a drawback to being passed as it is to the floor slab.

In particular, in order to reduce the impact sound, rubber, vinyl, waste tires, styrofoam or the like to put the buffer construction, but there is another problem causing unpleasant odor caused by the occupant after completion of construction.

In view of the above point, the present invention is installed between the floor slab and the foam concrete or between the floor slab and the finishing and adhesive mortar to absorb the shock vibration generated in the upper layer, in particular to significantly block the shock vibration The purpose of the present invention is to provide a shock absorbing panel between floors of multi-unit houses.

In addition, the present invention by converting the sound-absorbing material into a sound-absorbing vibration damping material using a different material to form a sandwich structure integrally to obtain a better effect on the prevention of noise to double the attenuation effect of the vibration frequency generated during impact vibration, It is an object of the present invention to provide a shock-absorbing panel between floors of a multi-family house, which hardly generates transmitted shock vibrations and at the same time reduces work processes during construction.

Figure 2 is a perspective view of the interlayer impact vibration absorbing panel according to the present invention, Figure 3 is a view showing a state in which the shock vibration absorbing panel of the present invention is applied to the interlayer noise protection structure of the apartment house.

As shown, the floor noise prevention structure 100 of the multi-family house according to an embodiment of the present invention is a floor slab 110 and the floor slab 110 constituting the floor of the multi-unit housing is installed above the floor slab 110, the heat insulation function Consists of foamed concrete 120 or finishing and adhesive mortar 150, etc., between the floor slab 110 and the foam concrete 120 or between the floor slab 110 and the finishing and adhesive mortar 150 Interlayer shock vibration absorbing panel 200 is installed.

Hereinafter will be described in detail with respect to the shock vibration absorbing panel 200, the main technical features of the present invention.

The shock vibration absorbing panel 200 is made of a damping sound insulating material (202, 202 ') integrally attached to one side of the vibration damping wood fiber 201 to be able to absorb and block the noise or shock vibration generated in the upper layer.

The vibration damping wood fiber 201 is manufactured in the form of a panel after coating a material having excellent vibration damping effect such as plastic resin, rubber or asphalt on the surface of the wood fiber (woodfiber), which is formed of a plurality of pores, Shock vibrations as well as noises not absorbed by the bubble concrete 120 are absorbed and damped while passing through the vibration damping woodfiber 201. In particular, the wood fiber has a lot of small bubbles or fine tubular pores therein, the air in the pores is vibrated by the sound waves generated by the impact vibration, the sound energy is converted into heat energy due to the friction generated at this time is absorbed. In addition, plastic resin, rubber, asphalt, etc. are coated on a number of wood fibers of wood fibers to partially absorb the shock vibration generated in the upper layer. Here, those skilled in the art of the present invention may be applied in various ways depending on the degree of porosity and material thickness of the vibration damping wood fiber according to the grade of impact vibration sound absorption performance.

In addition, the vibration suppressing sound insulating materials 202 and 202 'are integrally formed by pressing the vibration damping wood fibers 201 with an adhesive or high heat. In particular, the vibration damping sound insulating material (202, 202 ') is made of a foam of ethylene or foam urethane with a plurality of bubbles to prevent the shock vibration generated in the upper layer portion is transmitted to the lower layer along the floor slab 110 at the same time when the floor impact It cuts the generated vibration frequency to reduce the transmitted vibration frequency. That is, the vibration frequency is attenuated as the vibration frequency is dispersed in the fine air layer formed due to the foam molding of the vibration suppressing sound insulating materials 202 and 202 ', and the vibration frequency wavelength is reduced in the end, so that the impact vibration is reduced to the foam concrete 120 or the floor slab 110. Significantly reduces delivery.

Preferably, the vibration damping sound insulating materials 202 and 202 'are sandwiched and integrally provided in pairs on the upper and lower sides of the wood damping wood fiber 201, so that the impact vibration generated in the upper layer is different from each other, that is, the vibration damping sound insulating material. 202, the vibration damping woodfiber 201 and the vibration damping sound insulating material 202 'can be sequentially passed to increase the attenuation effect of the shock vibration.

In addition, in the present embodiment, a pair of vibration suppressing sound insulating materials 202 and 202 'are provided on the upper and lower sides of one vibration damping wood fiber 201, but those skilled in the art of the present invention have several layers for vibration damping. Wood fiber can be installed, and more than three vibration damping materials can be installed, and the installation location of the vibration damping wood fiber and the vibration damping material can be variously modified.

Therefore, the noise and shock vibration generated in the upper layer portion is partially absorbed while sequentially passing through the surface material 170, the finishing and adhesive mortar 150, the foamed concrete 120.

Subsequently, the vibration frequency generated during the sound wave and the shock vibration of the sound transmitted through the foam concrete 120 is attenuated by the vibration damping material 202 located above the vibration damping wood fiber 201.

Next, the vibration is passed through the wood fiber 201, the vibration vibration is first damped while passing through the plastic resin, rubber or asphalt coated on the wood vibration-proof wood fiber 201, then the wood fiber wood fiber Sound waves, that is, noise is significantly absorbed and reduced while passing, and then the remaining sound waves and shock vibration frequencies are blocked and absorbed while passing through the vibration suppressing sound insulating material 202 ′ positioned below the vibration damping wood fiber 201.

Finally, while passing through the bottom slab 110 is almost completely removed. As a result, the noise and shock vibrations transmitted to the lower layer are significantly attenuated so that the lower layer hardly feels the noise and shock vibrations.

In addition, lightweight impact sounds, such as the sound of falling small objects, are less than 58㏈ and weight impact sounds, such as children's running sounds, are required to be constructed with a standard floor structure. According to the interlayer noise prevention structure 100 according to the present invention, all the conditions of the interlayer floor impact sound can be satisfied, and enough to block and absorb noise and shock vibration even without thickening conventional concrete or strofoam. It becomes possible.

On the other hand, reference numeral 160 that is not described indicates a wall slab.

Figure 4 is a view showing a state in which the shock-vibration-absorbing panel of the present invention is applied to the inter-layer noise prevention structure of a multi-family house according to another embodiment.

As shown, the floor slab 110 and the floor slab 110 constituting the floor of the apartment house with the interlayer noise prevention structure constructed without the foam concrete 120 mainly performing the insulation function of the apartment house, the upper side of the floor slab 110 Consisting of a finish and adhesive mortar 150, etc. immediately installed in, it shows an embodiment in which the shock vibration absorbing panel 200 is installed directly between the bottom slab 110 and the finish and adhesive mortar 150.

Even when the interlayer shock vibration absorbing panel 200 is installed between the floor slab 110 and the finishing and adhesive mortar 150, the sound waves of the sound generated in the upper layer as well as the impact vibration are generated as described above. Even the vibration frequency is significantly attenuated and cut off.

The interlayer impact vibration absorbing panel of the multi-unit housing according to the present invention as described above is integrally formed with a vibration damping sound absorbing material that attenuates shock vibrations such as foamed urethane or foamed ethylene in the vibration damping wood fibers such as wood fibers By installing in the noise prevention structure, it is possible to remarkably reduce the noise and impact vibration even if the floor slab is not thick to reduce the impact vibration, thereby significantly preventing the inter-floor noise of apartments such as apartments. .

In addition, the present invention is formed by sandwiching a different material, that is, a vibration damping wood fiber and a vibration damping sound insulating material integrally to sandwich the structure of the vibration frequency generated by the impact vibration, so that almost no shock vibration delivered to the lower layer, Due to the construction of the interlaminar impact vibration absorbing panels, the work process is significantly reduced.

In the above, the present invention has been shown and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiment, and those skilled in the art to which the present invention belongs, without departing from the spirit of the technical idea of the present invention described in the utility model registration claims below. Any number of changes can be made.
