본 발명은 바닥충격음을 완충시키거나 감쇠시키기 위하여 시공되는 바닥충격음 방지 바닥구조 시공방법에 관한 것으로서, 특히 아파트와 같은 공동주택에서 상층으로 부터 하층에 전달되는 충격소음을 효율적으로 차단시켜 주도록 한 것이다.The present invention relates to a floor impact sound prevention floor structure construction method that is constructed to buffer or attenuate the floor impact sound, and in particular to effectively block the impact noise transmitted from the upper floor to the lower floor in a multi-family house such as an apartment.

일반적으로 바닥충격음이라고 하는 것은 물체의 낙하나 이동, 보행 등에 의해 슬래브가 진동하므로써 발생하는 소리로서, 이 때 발생하는 고체음은 극히 적은 감쇠로 여러 위치로 전달되어 구조체 표면을 진동시키므로서 직접 반사되는 공기 전달음처럼 인식되는 것을 말한다.Generally, the floor impact sound is a sound generated by the slab vibrating due to the falling, moving, or walking of an object. The solid sound generated at this time is transmitted to various positions with very little attenuation, and is directly reflected by vibrating the surface of the structure. It is something that is perceived as a sound of air.

이와 같은 바닥충격음에 대한 평가기준이나 측정방법은 1953년 독일에서 최초로 규격화된 이래 선진 각국에서는 바닥구조체의 차음성능향상에 대한 체계적인 연구가 지속적으로 이루어지고 있으나, 국내에서는 아직 이에대한 규격조차 이루어지지 못하고 있는 실정에 있다.Since the standard and evaluation method for the floor impact sound was first standardized in Germany in 1953, systematic researches on the improvement of sound insulation performance of floor structures have been continuously conducted in advanced countries, but domestic standards have not yet been established. There is a situation.

그러나, 근래에 들어서는 소음이 주기환경의 질을 좌우하는 중요한 요소의 하나로 인식되면서 내부소음원에 대한 불만족요인의 해결이 심각한 문제점으로 대두되고 있는 실정인데, 이는 쾌적한 주거환경에 대한 소비자의 욕구는 증대되고 있지만 공동주택의 바닥구조에 사용되고 있는 재료는 점점 얇아지면서 경량화되고 있는 실정임에 따라 내부소음원은 더욱 증가하고 있는데 원인이 있다고 볼 수 있다.However, in recent years, as noise is recognized as one of the important factors that affect the quality of the periodic environment, the resolution of dissatisfaction factors for the internal noise source has emerged as a serious problem, which increases the consumer's desire for a pleasant living environment. However, as the materials used for the floor structure of MDUs are getting thinner and lighter, the internal noise sources are increasing.

종래에는 이와같은 소음의 차단을 위하여, 바닥스라브의 상방으로 경량기포 콘크리트를 소정의 두께로 타설하는 방법을 사용하거나 또는 바닥스라브의 상방으로 일정두께의 발포 폴리에스틸렌을 깔아주는 방법을 사용하고 있으나, 이러한 방법들은 소음차단의 본래 목적보다는 난방이나 단열의 목적에 적합한 것이라서 차음성능을 개선하기 위한 목적에는 부적합하였다.Conventionally, in order to block such noise, a method of placing lightweight foamed concrete with a predetermined thickness above the floor slab or using a method of spreading a predetermined thickness of expanded polyesterene above the floor slab is used. However, these methods are not suitable for the purpose of improving the sound insulation performance because they are suitable for the purpose of heating or insulation rather than the original purpose of the noise blocking.

특히, 우리나라의 경우 공동주택의 난방방식이 온돌이라고 하는 바닥 판넬 히팅시스템(Floor Panel Heating System)의 일종이기 때문에, 단열 + 축열이라는 난방특성에 따른 다층구조를 이루고 있어 차음성능의 개선과 함께 단열성능을 동시에 만족시켜 주어야만 한다.In particular, in Korea, since the heating system of apartment houses is a type of floor panel heating system called ondol, it has a multi-layer structure according to the heating characteristics of insulation + heat storage. Must be satisfied at the same time.

본 발명은 상기한 바와 같은 종래의 문제점을 개선하기 위하여 안출한 것으로서, 우리나라 난방방식에 적합하면서 단열의 목적과 함께 차음성능을 향상시킬수 있는 바닥구조 시공방법을 제공함에 따라 공동주택에서 상층으로 부터 하층에 전달되는 충격소음이 효율적으로 차단되도록 하는데 그 목적이 있다.The present invention has been made in order to improve the conventional problems as described above, by providing a floor structure construction method that can improve the sound insulation performance with the purpose of heat insulation while being suitable for the heating method in Korea, from the upper floor to the lower floor in the apartment house The purpose is to effectively block the shock noise transmitted to the.

상기한 목적을 달성하기 위한 본 발명 형태에 따르면, 바닥기초스라브 위에 바닥층을 시공함에 있어서, 상기 바닥기초스라브 위로 접착물질이 혼합된 고무재를 깔고 그 위에 PE발포스폰지를 깔아 상기 고무재의 PE발포스폰지에 의해 차단층을 형성한 다음 상기 차단층인 PE발포스폰지 위로 발포콘크리트를 소정의 두께로 깔아 바닥층을 형성한 바닥충격음 방지 바닥구조 시공방법이 제공된다.According to the present invention for achieving the above object, in the construction of the bottom layer on the bottom foundation slab, the rubber material mixed with the adhesive material is laid on the bottom foundation slab and PE foamed sponge on the PE foamed sponge of the rubber material After forming a barrier layer by the foamed concrete over a predetermined thickness of the barrier foam PE foam is provided a floor impact sound floor construction method of forming a floor layer.

이하 본 발명을 실시예에 따라 보다 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to Examples.

첨부된 제1도 (a)(b)는 본 발명 방법에 의해 바닥구조가 시공된 상태를 실시예로 나타낸 단면도이고, 제2도는 바닥구조에 본 발명방법이 적용된 상태와 적용되지 않은 상태에서의 흡음특성을 비교하여 나타낸 그래프로서, 본 발명은 바닥기초스라브(1) 위에 바닥층(3)을 시공함에 있어서, 상기 바닥기초스라브(1) 위로 접착물질이 혼합된 고무재(2a)를 깔고 그 위로 PE발포스폰지(2b)를 깔아 상기 고무재(2a)와 PE발포스폰지(2b)에 의해 차단층(2)을 형성한 다음 상기 차단층인 PE발포스폰지(2b) 위로 기포콘크리트를 소정의 두께로 깔아 바닥층(3)을 형성한다.(A), (b) is a cross-sectional view showing an example of a state in which the floor structure is constructed by the method of the present invention, and FIG. As a graph showing a comparison of sound absorption characteristics, the present invention, when constructing the bottom layer (3) on the bottom foundation slab (1), the rubber material (2a) mixed with the adhesive material on the bottom foundation slab (1) and laid thereon PE foamed sponge (2b) is laid to form a barrier layer (2) by the rubber material (2a) and PE foamed sponge (2b), and then the foamed concrete to a predetermined thickness over the barrier layer PE foamed sponge (2b) The bottom layer 3 is formed.

상기에서 접착물질과 혼합된 고무제(2a)는 폐타이어를 분쇄하여 입자상으로 만들어 사용함이 바람직 한데, 이는 탄성과 복원력에 의해 충격 흡수기능을 갖도록 하면서 각 분쇄입자 사이의 공극에 의해 흡음성능을 갖도록 하기 위함이다.The rubber agent 2a mixed with the adhesive material is preferably used to make the waste tires into particles to crush the waste tires, which have a sound absorption function by the elasticity and the restoring force, and have the sound absorbing performance by the voids between the crushed particles. To do this.

따라서, 고무재(2a)인 폐타이어 분쇄입자를 우레탄 바인더 등과 같은 접착물질과 혼합한 다음 이 혼합물질을 바닥기초스라브(1) 위로 소정의 두께만큼 깔고 약 2시간 정도 기다리면 상기 접착물질로 사용된 우레탄 바인더가 응고되고, 상기 우레탄 바인더가 충분히 응고되고 나면 계속해서 수개의 기포층을 갖는 PE발포스폰지(2b)를 고무재(2a) 위로 깐다.Therefore, the waste tire crushed particles of the rubber material 2a are mixed with an adhesive material such as a urethane binder, and then the mixture is laid on the bottom foundation slab 1 by a predetermined thickness and waited for about 2 hours to be used as the adhesive material. After the urethane binder has solidified and the urethane binder has solidified sufficiently, the PE foamed sponge 2b having several bubble layers is subsequently covered on the rubber material 2a.

그 다음 차단층(2)인 PE발포스폰지(2b) 위로 기포콘크리트를 소정의 두께로 깔아놓은 다음 일정시간이 지나면 상기 기포콘크리트가 굳게 되면서 바닥층(3)이 형성되므로 본 발명 바닥충격음 방지 바닥구조가 시공 완료된다.Then, the foamed concrete is laid over a predetermined thickness on the PE foamed sponge 2b, which is the blocking layer 2, and then the foamed concrete is hardened after a predetermined time so that the bottom layer 3 is formed. Construction is completed.

상기한 본 발명 바닥구조 시공방법은 서로 다른 재질로서 복합층을 형성한 것으로, 임의의 재질에 음파가 입사되면 입사에너지의 일부는 반사되고, 나머지는 흡수되는 성질에 따라 음이 어떤 재료에서 다른 재료의 접하는 경계면에 부딪힐 때 반사파와 전달파로 나뉘어져 흡음과 차음이 이루어지는 성질을 이용한 것이다.In the above-described floor construction method of the present invention, a composite layer is formed of different materials, and when sound waves are incident on an arbitrary material, part of the incident energy is reflected, and the rest of the material is different from the material in which the sound is absorbed. When it hits the interface, it is divided into reflected wave and propagation wave, so that sound absorption and sound insulation are made.

이하 본 발명 방법에 의해 시공된 바닥충격음 방지 바닥구조에 의해 바닥충격음이 방지되기 까지의 과정을 구체적으로 설명하면 다음과 같다.Hereinafter, the process until the floor impact sound is prevented by the floor impact sound prevention floor structure constructed by the present invention will be described in detail.

바닥층(4)에 충격음이 전달되면 상기 바닥층을 통과한 음은 차단층(2)인 PE발포스폰지(2b)를 먼저 투과하면서 일차적으로 충격완충이 이루어지고, 상기 PE발포스폰지(2b)를 투과한 음은 다시 우레탄 바인더가 혼합된 고무재(2a)를 투과하면서 이차적으로 충격완충이 이루어짐과 동시에 상기 PE발포스폰지(2b)와 고무재(2a)의 다공질 내로 음이 흡입되므로 하층으로의 음의 전달이 현저하게 줄어드는 것이다.When the impact sound is transmitted to the bottom layer 4, the sound passing through the bottom layer first penetrates the PE foamed sponge 2b, which is the blocking layer 2, and the impact buffer is first made, and the PE foamed sponge 2b is transmitted. As the sound penetrates the rubber material 2a mixed with the urethane binder again, the impact is secondarily absorbed, and at the same time, the sound is sucked into the porous material of the PE foamed sponge 2b and the rubber material 2a. This is a marked decrease.

즉, 음이 이중구조의 매질을 통과할 때 단일 매질을 통과할 때 보다 현저한 음압레벨의 감소를 가질 수 있는 사실은 제2도와 같이 흡음특성의 도표를 통해서 확실히 알 수가 있다.In other words, it can be clearly seen from the diagram of sound absorption characteristics as shown in FIG. 2 that sound can have a significant decrease in sound pressure level when passing through a single medium and through a single medium.

또한 본 발명 방법에서 고무재(2a)에 접착되는 PE발포스폰지(2b)는 시이트 형상으로 만들어 필요에 따라 원하는 만큼 재단하여 사용하면 된다.In the method of the present invention, the PE foamed sponge 2b adhered to the rubber material 2a may be formed into a sheet shape and cut and used as desired.

한편 본 발명 바닥구조 시공방법에 의해 바닥구조를 시공할 때 제1도 (b)에서와 같이 차단층(2)인 고무재(2a)와 PE발포스폰지(2b)를 바닥기초스라브(1)에서 벽체(4)를 따라 상측으로 소정의 높이만큼 연장하면 후술하는 바와 같은 본 발명의 효과가 더욱 증대됨은 이해 가능하다.On the other hand, when constructing the floor structure by the floor construction method of the present invention, as shown in FIG. 1 (b), the rubber material 2a and the PE foamed sponge 2b, which are the barrier layer 2, are formed on the bottom foundation slab 1. It is understood that the effect of the present invention as described later is further increased by extending upward by a predetermined height along the wall 4.

따라서 제1도 (b)와 같이 본 발명 바닥구조가 시공된 상태에서는 바닥기초스라브(1)와 바닥층(3) 사이 및 벽체(4)와 바닥층(3) 사이에 고무재(2a)와 PE발포스폰지(2b)로 된 차단층(2)이 형성되어 있으므로 바닥기초스라브(1)가 바닥층(3)과 완전히 절연된 상태임은 물론 벽체(4)가 바닥층(3)과 상당부분 절연된 상태인 뜬바닥 구조가 되어 다음의 표 1에 나타낸 바와 같이 바닥충격음에 대한 차단성능이 향상됨을 알 수 있었다.Therefore, in the state where the floor structure of the present invention is constructed as shown in FIG. 1 (b), the rubber material 2a and the PE foam are formed between the bottom foundation slab 1 and the bottom layer 3 and between the wall 4 and the bottom layer 3. Since the blocking layer 2 made of the sponge 2b is formed, the bottom foundation slab 1 is completely insulated from the bottom layer 3, and the wall 4 is substantially insulated from the bottom layer 3. It became a floating floor structure, as shown in the following Table 1 was found to improve the blocking performance against the floor impact sound.

상기 경우에는 바닥기초스라브(1)의 두께는 140mm로 하였고, 고무재(2a)와 PE발포스폰지(2b)로 된 차단층(2)의 두께는 50mm로 하였다.In this case, the thickness of the bottom foundation slab 1 was 140 mm, and the thickness of the barrier layer 2 made of the rubber material 2a and the PE foamed sponge 2b was 50 mm.

그러므로 본 발명은 서로 다른 매질로 된 고무재와 PE발포스폰지가 바닥충격음의 차단효과를 높여 공동주택생활에서 실내소음의 전달에 의한 피해를 막아줌에 따라 쾌적한 주거환경이 제공되는 효과가 있다.Therefore, the present invention has the effect of providing a comfortable living environment as the rubber material and PE foamed sponge made of different media to increase the blocking effect of the floor impact sound to prevent damage caused by the transmission of indoor noise in the apartment life.
