Description

A soundproof mat and an establishment method thereof,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound insulating material for preventing floor impact sound transmission and a method of installing the sound insulating material for preventing the transmission noise of a light weight impact sound and a heavy impact sound transmitted from a floor surface to a lower layer of a single-

More specifically, the sound insulating performance is determined in the middle and high frequency bands by the sound of the human being or the sound of the external impact sound, and the thickness of the surface layer is 10 to 15 mm and the sound density is 70 to 120 kg / The floor impact sound transmission level is minimized in the middle and high frequency bands,

A light-weight impact sound attenuator, which is a surface layer composed of a thickness of 10 to 15 mm and an apparent density of 70 to 120 kg / m < 3 > provided on an upper part of a base material having a thickness of 15 to 25 mm according to the present invention for improving the sound- Improves the proper thickness and apparent density and improves the sound insulation effect of the relatively light impact sound;

In the case of a heavy impact sound due to walking or vibration of a person, a sound insulation rating is determined in a low frequency band. Thus, a sound impact sound having a thickness of 5 to 10 mm and an apparent density of 60 to 80 kg / The concave and convex portions of the concave portion and the blocking portion are reduced to the maximum dynamic elastic modulus and the transmission noise caused by the impact sound transmitted from the upper layer moves laterally through the passage of the heavy impact sound noise portion and is easily discharged to the outside,

The present invention relates to a sound insulating material for preventing floor impact sound transmission and a method of installing the sound insulating material.

Generally, a floor impact sound is classified into a light impact sound due to a human speech or an external sound, and a heavy impact sound due to a person's walking or vibration,

The influence of the floor structure on the propagation characteristics and the influence of the floor structure varies depending on the characteristics of the impact force, the vibration characteristics of the bottom structure, and the acoustic characteristics of the bottom room. The degree of influence of the bottom structure depends on the thickness, area, It depends on the rigidity of the entire slab, such as construction management.

However, since the spatial conditions of the underfloor room as a general residence space are similar to each other, the floor impact sound insulation performance of Korea varies depending on the characteristics of the floor structure.

In addition, the general floor structure in Korea is caused by the direct impact of the concrete slab (SLAB). To solve this problem, a floating floor structure is applied to the slab (SLAB) (Hereinafter referred to as "sound insulating material") is installed on the upper part of the furnace, so that the impact energy applied to the ondol layer is not transmitted to the slab directly structured;

When the cushioning material is installed on the upper part of the slab, which is the floor of the building, the elastic modulus of the air is added because the air escapes laterally, but when the cushioning material is thin, the elastic modulus is large. Since the coefficient is also large (twice as thick as half the thickness), the bottom effect does not appear particularly at low frequencies.

The background of the present invention will be described below. The background art of the present invention is disclosed in Korean Patent Laid-Open Publication No. 10- 2012-0032608 (published on Apr. 26, 2012) Quot ;, " Sound insulating material for preventing interlayer noise and its installation method ", and further describes the technical background and further problems of the prior art based on the background of the invention.

As shown in Fig. 1;

The structure of the building floor 40 of the conventional apartment house is composed of the floor slab layer 41, the foamed concrete layer 42, the finish mortar layer 43, the ondol furnace pipe 60, And the building wall surface 50 is constituted by a concrete wall surface 51,

The floor slab layer 41 on the floor of the building and the floor slab layer 41 on the floor of the building are arranged in the order of the bottom slab layer 41 and the floor slab layer 41. In order to minimize heavy noise due to walking and vibration of a person, The sound insulating materials 100 and 200 are installed between the foamed concrete layers 42 and the insulating material 52 is attached to the concrete wall surface 51 of the building wall surface.

The sound insulating materials 100 and 200 used in the prior art include a base material 201 made of styrofoam (EPS) or ethyl vinyl acetate (EVA), a rubber material, and a semicircular or polygonal material laminated on the bottom of the base slab layer 41 A sound insulating material having an elliptical laminated portion 202 is mainly used,

In the case of the EPS sound insulating material 100, the sound insulating material as described above is excellent in heat insulation and heat insulation effect due to minimal heat loss, but light sound or heavy sound noise is less effective in sound insulation due to the material of the base material, Noise is transmitted to the lower layer, thereby causing many problems in terms of function as a sound insulating material;

In addition, by the construction of the sound insulating material having the semicircular or oval-shaped laminate portion 202, the load transmitted from the bottom surface of the upper layer is transmitted to the semicircular or elliptical-shaped laminate portion 202 and the outer shape of the laminate portion is deformed The sound insulating material is damaged and the load is not supported, which makes it difficult to use the sound insulating material.

In order to solve the above-described problems, a substrate 201 made of ethyl vinyl acetate (EVA) or rubber, and a semi-circular or elliptical laminated portion

There is provided a sound insulating material 200 having a structure for preventing noise by minimizing a contact area with which the bottom slab layer 41 is in contact with the floor slab layer 41. However, However,

By the construction of the sound insulating material having the semicircular or oval-shaped laminate part 202, the load transmitted from the bottom surface of the upper layer is transmitted to the semicircular or oval-shaped laminate part 202, And the load is not supported, which makes it difficult to use.

Further, in the method of installing the sound insulating materials 100 and 200, the sound insulating materials 100 and 200 are installed on the floor slab layer 41, which is the bottom surface of the building, the foam concrete is poured to form the foam concrete layer 42, Because of the installation method in which the floor covering material 70 is installed after the ondol furnace pipe 60 is installed and the finishing mortar layer 43 is finished,

The sound insulating materials 100 and 200 are laminated on the floor slab layer 41 and the sound insulating materials 100,

When the foamed concrete layer 42 is buried in the upper part of the floor slab layer 200, the sound insulating material flows from the upper part of the floor slab layer 41, or is partly released to the outside from the installation point, Problems are occurring;

There is a problem that the noise generated in the upper layer is transmitted to the lower layer in the actual use after the construction, and the noise preventing effect as a sound insulating material is remarkably deteriorated.

In addition, the sound insulating material produced by using the existing EVA as the main material has a disadvantage in that it can not form a low dynamic elastic modulus. Therefore, the total thickness of the sound insulating material is 20 to 45 mm, And the floor impact sound performance was significantly lowered;

This is because, although it is recognized that the floor impact sound performance is improved when the dynamic modulus of elasticity is lowered, it is not possible to design the floor impact sound properly so as not to interfere with the flow of air at the time of the foam technique and floor impact sound.

Accordingly, there is an urgent need to develop a sound insulating material and a method of installing the sound insulating material in a structure in which the light transmission of the light impact sound transmitted from the bottom surface of the upper layer to the lower layer and the interlayer transmission noise of the heavy impact sound are effectively prevented.

By the sound insulating material for preventing floor impact sound transmission according to the present invention and the installation method thereof,

Solving the problems of the prior art;

In particular, the present invention improves the proper thickness and bulk density of the lightweight impact sound absorber, which is the surface layer provided on the base material of the sound insulating material of the present invention, and improves the sound insulation effect of the light impact sound relatively.

The sound insulation modulus of the sound insulation sound absorber according to the present invention is minimized by minimizing the dynamic modulus of elasticity of the concavo-convex portion and the blocking portion of the heavy impact sound noise portion, and the transmission noise due to the impact sound transmitted from the upper layer is shifted in the lateral direction , It is easily discharged to the outside,

The dynamic modulus required for heavy impact sound and the transverse arrangement of the air discharge system are largely prevented, so that heavy impact sound transmission is largely prevented;

Excellent sound insulation effect and easiness of installation, workability is simultaneously improved; The present invention provides a sound insulating material for preventing floor impact sound transmission and a method for installing the sound insulating material.

Generally, when a floor is constructed by installing a sound insulating material on a slab, the elastic coefficient of the air is added because the air escapes in the lateral direction. However, when the thickness of the sound insulating material is thin, the elastic coefficient is large and the elastic modulus of air is also large (Twice as thick as half the thickness).

Therefore, when the sound insulating material of the present invention is examined, the sound insulating performance is determined in the medium and high frequency bands in the case of a light impact sound due to human speech or external transmission sound,

It is noted that the sound insulating material having a surface layer thickness of 10 to 15 mm and a high density of an apparent density of 70 to 120 kg / m < 3 > minimizes the floor impact sound transmission level in the middle and high frequency bands,

In the case of a heavy impact sound due to walking or vibration of a person, a sound insulation rating is determined in a low frequency band,

It consists of a sound insulation material with a dynamic modulus of elasticity required by heavy impact sound and a transverse air discharge system to prevent heavy impact sound transmission.

Therefore, the sound insulating material of the present invention has a problem of the sound insulating material of the prior art, and in order to improve the heavy impact sound performance, the sound insulating material of the sound insulating material for lowering the dynamic modulus of the sound insulating material, Height, width, spacing, etc. were designed and manufactured through long-term actual field tests;

The heavy impact sound absorber constituted by the concave-convex part, the cut-off part and the flow path of the present invention allows the air in the air layer, which is a transfer noise generated by a single impact, to escape at a time when the impact sound is applied from the upper layer. The low frequency resonance at the time of the next shock caused by the air is prevented from being generated, and the transmission of the heavy impact sound is remarkably prevented;

In order to improve the performance of the light-weight impact sound, the light-weight impact sound absorber, which is a surface layer provided on the upper surface of the sound-insulating material of the present invention, has a proper density of density, And a sound insulating material for preventing impact sound transmission.

This does not limit the appropriate thickness and density of the light impact sound impact portion and the heavy impact sound impact portion to simply numerical values;

The sound insulation effect of the light weight impact sound and the heavy impact sound is improved compared to the sound insulation material of the related art by the appropriate thickness and density of the light impact sound insulation portion and the heavy impact sound insulation portion. It is clear that this is not just a numerical limitation.

As can be seen from the above Table 1, the sound insulating material of the ethyl vinyl acetate material of the present invention and the comparative example 1 satisfied the standard values of the dynamic elastic modulus and the dimensional stability, Of the soundproofing material of the hydrofoil material satisfied the standard value of the dynamic modulus of elasticity, but it was found that the dimensional stability property property item was below the standard value and had problems in use;

In particular, in the sound insulating material of the ethyl vinyl acetate material of Comparative Example 1, defects due to tearing of the sound insulating material due to the load transmitted from the foamed concrete layer, the finish mortar layer, and the flooring material layer, It has been found that there is a problem in load bearing capacity,

The sound insulating material of the Surochloform material of Comparative Example 2 also suffered a failure due to a severe damage to the sound insulating material due to the load transmitted from the foamed concrete layer, the finish mortar layer and the flooring material layer, which is the bottom surface of the building installed on the sound insulating material, It turned out to be a significant problem.

In addition, the embodiment of the present invention proved to be superior in terms of the dynamic modulus of elasticity, dimensional stability, and load-bearing property in comparison with Comparative Examples 1 and 2;

It has been found that when the embodiment is installed on the floor slab layer, which is the floor of the building, and when the foamed concrete layer and the finishing mortar layer are placed on the upper part of the sound insulating material,

In Comparative Examples 1 and 2, since the sound insulating material is directly laminated on the floor slab layer, which is the bottom surface of the building, the sound insulating material is partially removed from the upper part of the floor slab layer at the upper part of the floor slab layer.

As shown in Tables 2 and 3, the sound insulation performance of the light-weight impact sound and the heavy impact sound of the sound insulating material according to the present invention is remarkably superior to that of the first and second comparative examples 1 and 2 due to the provision of the light- ;

Particularly, the sound insulation performance of the light-weight impact sound and the heavy impact sound of the sound insulating material of the embodiment proved to be the best in the first grade;

The sound insulating material made of only the sound insulating substrate made of the ethyl vinyl acetate material of the comparative example 1 was found to be poor in sound quality because the light weight impact sound class 4 and heavy impact sound were judged to be rejected outside the grade,

In the sound insulating material composed of the sound insulating substrate made of the Sicrofoam material of Comparative Example 2, the sound difference results of the light impact sound and the heavy impact sound were both determined to be out of grade and it was found that sound insulating performance as a sound insulating material was problematic.
