The present invention relates to an interlayer noise prevention material, and more particularly, waste poly pulverized on the inner surface of a plastic structure having a certain area in order to effectively block various floor impact noises transmitted from the upper floor to the lower floor in apartment houses such as apartments. After absorbing and curing the sound-absorbing material mixed with urethane and lime in a certain ratio, and inserting the cover material, the second sound-absorbing material composed of styrofoam is laminated and bonded to the lower part, and the uneven part of the side and the outer surface of the upper surface for extension coupling and installation are covered. Correspondingly forming the portion and its receiving portion, and by providing a plurality of coupling grooves on the upper surface to provide a noise preventing material that enables easy installation of the boiler tube, in addition to minimizing noise and improving the insulation effect and energy saving, It effectively blocks the light impact sound and heavy impact sound, making its construction work excellent in soundproofing, moisture proof, and insulation effect It is about interlayer noise prevention material which can improve the property further.

Due to the unique heating structure of Ondol, Korea has built a lightweight concrete with a specific gravity of about 0.5 in the upper part of the slab when building the floor of a multi-family house to secure the horizontal layer for heating coils and the insulation layer at the bottom of the heating coil. It is common to complete the floor structure by installing heating coils and placing finishing mortars with a thickness of about 40 to 60 mm.

In addition, in the interlayer noise suppression industry, various materials have been developed and released.In the early stages, waste tire grinding was mixed with adhesive components such as acrylic, urethane, acrylic, etc. In this case, it is difficult to improve sound insulation and insulation because light weight concrete that is placed on top of this cushion material is very easily absorbed. Some have proposed soundproof plates using waste tire chips, and some used waste tire chips and cork powder. Although the proposed sound absorbing materials are used, both of these technologies do not fundamentally improve the problems of sound insulation and thermal insulation deterioration of the waste tire chip, and have problems to be improved, such as inconvenience of construction.

Therefore, in recent years, by forming protrusions on the surface of the polymeric foam material, the sound insulation is improved by absorbing, reflecting, and canceling the incident noise. However, the interlayer noise is transmitted in the form of vibration, so that the absorption, reflection, and offset effects are achieved. It is difficult to expect satisfactory performance, and some have proposed a method using a pulverized synthetic resin such as ethylene vinyl acetate, but this still has the same tendency and high thermal conductivity as waste tire chips. .

Since foam styrene, which has been used mainly as a heat insulating material for buildings, has a certain effect of reducing floor impact noise while being a heat insulating material, many sites use only this foam styrene as an interlayer noise prevention material and finish the surface with foam styrene as a main material. It is used as a noise preventing material between layers by changing only the texture through treatment, but it also does not deviate from the category of foamed styrene, and it is competitive by compounding with foamed styrene, foamed ethyl vinyl acetate, polyurethane foam, and soundproof sheet containing a large amount of inorganic materials. Efforts have been made to create floor impact sound absorbers.

However, the interlayer noise prevention material is not significantly different from the properties of the foamed styrene, and it is difficult to expect a high floor impact sound reduction effect by ignoring the aspects of light shock sound and heavy shock sound, which are the basic factors of floor impact sound reduction.

The impact sound is classified into a light impact sound and a heavy impact sound. The light impact sound is an old sound, that is, a coin falling sound or a high sounding sound of a high heel. Since dull sounds such as playing sounds are transmitted as vibrations, it is a reality that the existing sound insulation material does not show the effect of reducing the weight impact sound in the existing floor structure.

In recent years, such a floor impact sound insulation material forms a styrofoam layer having heat insulation, soundproofing, and moisture resistance, and a porous upper and lower nonwoven layer bonded to upper and lower surfaces of the styrofoam layer through upper and lower adhesive layers, respectively. An interlayer noise prevention material composed of a natural foamed rubber layer having chemical resistance, oil resistance, abrasion resistance, and corrosion resistance with an embossed surface formed on the upper side was proposed to reduce the weight impact sound. There still remained a problem that could not effectively block the heavy shock sound transmitted by.

In addition, in the construction method, after installing the sound insulation material, it was common to interpose a separate intermediate member on the upper part and finish after separately installing the boiler tube on the upper part.

The present invention has been researched and created in order to fundamentally solve the problems of the prior art described above, and the object of providing the same is to effectively block various floor impact noises transmitted from the upper floor to the lower floor in an apartment house or the like. A sound absorbing material mixed with waste polyurethane and lime mixed at a predetermined ratio is injected into the inner surface of the plastic structure having a predetermined area, and the cover material is inserted into the cover material. It is to provide a noise preventing material that is formed to correspond to the uneven portion and the upper portion of the lid and its receiving portion, and to form a plurality of coupling grooves on the upper surface to enable easy installation of the boiler tube.

Another object of the present invention by providing the noise prevention material as described above to minimize the noise and improve the insulation effect and energy saving, in particular, the light impact sound and heavy impact sound by effectively blocking the construction while making excellent sound insulation and moisture proof, insulation effect The purpose is to improve workability.

Another object of the present invention is to enable the use of recycled waste polyurethane pulverized on the inner surface of the plastic structure to provide a cost-effective noise prevention material and at the same time to achieve the environmental pollution prevention effect associated with the disposal of waste polyurethane. have.

In order to achieve the above object, the present invention will be more clearly described with reference to the accompanying drawings.

That is, the present invention is as shown in the accompanying drawings, Figures 1 to 3,

Inside the plastic structure 1 having a predetermined area, a sound absorbing material 2 composed of pulverized waste polyurethane and lime mixed in a predetermined ratio is seated and cured, and an outer surface of the plastic structure 1 having a predetermined area coincides with the inner surface of the plastic structure 1. It has a constant thickness and has a cover member 3 is formed therein a plurality of spaces 31 are combined,

A second sound absorbing material 4 composed of foamed foam foam having a locking jaw 41 corresponding to the inner surface of the plastic structure 1 and the lower portion thereof is extended to the outer surface of the plastic structure 1 is fitted therein. Is configured to be possible,

The plastic structure 1 has a recess 11 and a convex portion 12 correspondingly formed to extend outwardly, and a lid 13 and a receiving portion 14 of the upper surface outer side thereof are integrally formed. In the middle of the inner surface, a plurality of locking jaws 15 for preventing the separation of the cover member 3 is formed at a predetermined interval,

In the upper surface of the plastic assembly 1, a plurality of coupling grooves 16 are formed at equal intervals toward the inner surface, so that a plurality of protrusions 17 are formed at each intersection of the reinforcing bar 18 on the inner surface thereof. Formed integrally,

The coupling groove 16 is composed of a coupling member 5 having a coupling hole 51 formed at one side of the middle portion to be detachably coupled with a piece 6 and arranged at the upper portion of the boiler tube 7.

Referring to the operation of the present invention made of such a structure as follows.

First, the plastic structure (1) is possible to extend and the inside of the sound absorbing material (2) and the cover material (3) is designed to be able to be filled, combined, injection, mass production is very simple and easy to manufacture it.

As shown in the accompanying drawings with a plurality of plastic structure (1) of the present invention, as shown in Figure 1, the locking step (15) formed on the inner surface of the mixture of pulverized waste polyurethane and lime mixed in a predetermined ratio in the reversed state In the state where the particles are located between the reinforcing bar 18 and the protrusion 17 formed on the inner surface of the plastic structure 1 when left at normal room temperature for several hours while being filled up to the bottom of the flat state. It will harden and dry.

In this state, the pulverized pepolyurethane mixtures are agglomerated and cured with each other by a lime component, and the waste polyurethane particles which are cured while being mixed on their inner surfaces are already porous, and a plurality of equalized air layers are formed during the curing process. Irregularly formed, the voids eventually become sound absorbing holes, which are converted into hardened sound absorbing material 2.

In this state, the sound absorbing material 2 is fixed to the inner surface of the plastic structure 1, respectively, since it maintains a certain weight, so that a small amount of space 31 is formed by applying a slight force to the locking jaw 15. When the cover material 3 having a thickness is fitted, the sound absorbing material 2 is prevented from being separated by the cover material 3 even when the cover material 3 is inverted.

In this state, the second sound absorbing material 4 made of foamed styrofoam is forcibly inserted into the upper portion of the cover material 3 by applying a slight force, or fixed by using a general adhesive to be supported by the locking jaw 41. While the second sound absorbing material 4 is fixed while maintaining the state protruding downward, the respective outer surface is maintained in a state consistent with the outer surface of the plastic structure (1) does not interfere during assembly work.

Repeated mass production in such a state and transfer it to the site to determine the assembly direction according to the uneven portion to extend the combined state in the reversed state, using the binding member (5) in the upper, and bind the boiler tube (7) and install. ,

At this time, if the main portion 11 and the convex portion 12 for the coupling formed on the side of the plastic structure (1) in the direction to combine, the cover portion 13 formed at the same time and extends to one side of the upper surface thereof is coupled with Being seated on the upper surface of the receiving portion 14 of the other to serve to block the noise that can be transmitted through the space, that is, the gap that can be generated on each side of the pole.

In addition, the sound absorbing and scavenging action of the noise is blocked first in the sound absorbing material (2) made of a waste polyurethane mixture, and blocked in the second sound absorbing material (4) consisting of styrofoam bonded to the lower portion to minimize the noise. ,

At this time, the sound is interposed between the sound absorbing material 2 and the second sound absorbing material 4 to prevent the detachment of the sound absorbing material 2, and thus the noise is provided in the space 31 of the cover material 3 to be transmitted to the vibration. Effective blocking of the heavy shock sound is achieved.

In this state, a plurality of coupling grooves 16 formed on the upper surface of the plastic structure 1 are selected to match the arrangement interval of the boiler tube 7 through the coupling hole 51 formed in the binding member 5. Assemble the piece (6) and fix it first,

Since it usually has the same structure as a cable tie, when the other end is contracted by the other end of the coupling portion formed on the end, the coupling and fixing of the boiler tube 7 are made very easy and smooth.

This work is completed repeatedly and the finishing work on the upper part, so that the construction is very simple and robust also can be improved workability according to the construction work.

On the other hand, the accompanying drawings Figures 4 and 5 show another embodiment of the present invention, which forms a plurality of coupling holes 32 in the lower outer peripheral portion and the middle portion of the cover member 3 and from the bottom to the top It shows an example in which a plurality of support legs (8) made of a rubber member is fitted in the state protruding downward.

When it is combined with the upper part of the concrete slab, it forms an air layer trapped between the slab layer (not shown) and the cover member 3 generated by the support leg (8) to maximize the blocking effect of the heavy impact sound The note shows an example.

6 to 8 are a perspective view and a cross-sectional view showing another embodiment of the present invention, in which a second insulating material 2 or a support leg 8 formed of a styrofoam is coupled to the cover 3. The extension part 19 is integrally formed on the outer circumference of the upper surface of the plastic structure 1, and the insulation surface 9 is inserted into and fixed to the inner surface of the plastic structure 1, and then a plurality of boiler tube fixtures 10 are fixed thereon. An example of spaced apart is shown.

In this case, the heat insulator 9 may be made of a polyurethane sheet material having a predetermined thickness, or may be achieved by input hardening the pulverized waste polyurethane mixture.

In addition, the boiler tube fixture 10 is preferably composed of a metal material having a clamp 10 'formed on the upper part of the belt member, which is directly fixed to the upper surface of the heat insulating material 9 as shown and described in the present invention. It may be used or fixed to the upper surface of the extension portion 19 to improve the bearing force.

In the embodiment of the present invention as described above, the use of the heat insulator (9) to not transfer the heat of the boiler tube 7 to the lower priority, but due to the material properties of the heat insulator can be used in parallel with the insulation and sound insulation excellent heating Simultaneously with the effect of sound is to work.

Hereinafter, other parts are the same as the present invention described above, so a separate description will be omitted.

According to the present invention, in a multi-family house such as an apartment, waste polyurethane, lime, and cement crushed on the inner surface of a plastic structure having a certain area to effectively block various floor impact noises transmitted from the upper floor to the lower floor are in a certain ratio. After mixing and absorbing the sound absorbing material mixed into the cover material, and inserting the cover material, the second sound absorbing material composed of styrofoam is laminated and combined at the bottom, so as to minimize the noise, improve the insulation effect and save energy, in particular, the light impact sound and heavy impact sound It effectively blocks and improves soundproofing, moisture proofing, and heat insulation effect, while forming uneven parts on the side and a cover part and its receiving part outside the upper surface for extension coupling and installation, and forming a plurality of coupling grooves on the upper surface of the boiler tube. By allowing easy installation, the construction work is not only simpler, but also crushed waste It is obvious that this invention is a very advantageous invention that makes it possible to achieve the low cost of noise-preventing material by reusing the polyurethane and at the same time to achieve various useful effects such as preventing the environmental pollution associated with the disposal of the waste polyurethane. .
