발명은 건축물의 층간바닥 충격음 차단구조에 관한 것으로서, 더욱더 상세하게는 건축물의 바닥슬라브와 기포콘크리트 사이에서 경량 및 중량 진동을 효과적으로 절연시킴과 동시에 음압을 흡수하여, 상측 바닥의 충격에 의한 소음이 바닥슬라브를 통해 하층으로 전달되는 현상이 방지되도록 하는 건축물의 층간바닥 충격음 차단구조에 관한 것이다. The present invention relates to an interlayer floor impact sound blocking structure of a building, and more particularly, it effectively insulates light weight and weight vibration between the floor slab and foam concrete of the building, and simultaneously absorbs sound pressure, so that the noise caused by the impact of the upper floor is reduced. It relates to an interlayer floor impact sound blocking structure of the building to prevent the phenomenon that is transmitted to the lower floor through the slab.

반적으로 바닥과 벽체를 공유하는 공동주택이나 아파트와 같은 건축물은 고층화되면서 무게를 줄이기 위해 바닥슬라브를 경량제로 사용하거나 바닥 두께를 얇게 시공하고 있어, 건축물의 직상층에서 발생되는 충격음이 직 하층부로 전달되는 소음이 가장 문제시되고 있다.On the other hand, buildings such as apartments and apartments that share floors and walls have high floors, and use floor slabs as a light weight or thin floors to reduce weight, so that the impact sound from the upper floor of the building is transmitted to the lower floor. Noise is the most problematic.

상기 건축물의 직상층에서 발생되는 충격음은 경량 충격음과 중량 충격음으로 구분되며, 경량 충격음은 주로 물건이 떨어질 때 발생하는 소음을 말하고, 중량 충격음은 주로 사람이 뛸 때 발생하는 소음을 말하며, 이러한 충격음은 윗층의 바닥 구조물에 가해진 충격이 슬라브에 진동으로 전달된 다음 아래층에 소음으로 방사된다.The impact sound generated on the upper floor of the building is divided into a light impact sound and a heavy impact sound, and the light impact sound mainly refers to noise generated when an object falls, and the heavy impact sound mainly refers to noise generated when a person runs. The shock applied to the floor structure on the upper floor is vibrated to the slab and then emitted as noise on the lower floor.

따라서 종래에도 건축물의 직상층에서 발생되는 충격음이 직 하층부로 전달되지 않도록 하기 위해 도 1에 도시하고 있는 바와 같이, 온돌마루등과 같은 마감재(300')가 상부면에 시공되는 마감몰탈(200')과 콘크리트구조물로 타설되는 바닥슬라브(100') 사이에 고무재와 같이 자체 탄성력을 갖고 있는 층간방진재(400')를 설치하여 시공하고 있다.Therefore, in order to prevent the impact sound generated in the upper floor of the building in the prior art as shown in Figure 1, finishing mortar (200 '), such as ondol floor, such as finishing floor (300') is constructed on the upper surface ) Is installed between the floor slab (100 ') that is poured into the concrete structure and the interlayer dustproof material (400') having its own elastic force, such as rubber material.

이러한 종래 건축물의 층간바닥 충격음 차단구조는 건축물의 상부층에서 발생된 충격음이 마감몰탈(200')과 바닥슬라브(100') 사이에 설치되어 있는 층간방진재(400')에 의해 진동이 절연됨과 동시에 흡음되어, 건축물의 직상층에서 발생된 충격음이 직하층부로 전달되는 것을 억제시키고 있다. In the structure of the conventional floor-floor impact sound blocking structure, the shock sound generated at the upper floor of the building is sound absorbed at the same time as the vibration is insulated by the interlayer dustproof material 400 'installed between the finishing mortar 200' and the floor slab 100 '. Thus, the impact sound generated at the upper floor of the building is suppressed from being transmitted to the lower floor.

그러나 이러한 종래 건축물의 층간바닥 충격음 차단구조는 마감몰탈(200')의 저면과 바닥슬라브(100')의 상부면에 접하도록 설치되는 층간방진재(400')의 자체 탄성력에 의해서만 충격 시 발생되는 진동이 절연됨과 동시에 흡음되는 관계로, 저주파 대역에서 차음효과가 결정되는 중량 충격음의 경우는 그 소음을 제대로 다 흡수하지 못하게 되는 문제점이 있었다.However, the structure of the interlayer floor impact sound blocking structure of the conventional building is a vibration generated when the impact is generated only by its own elastic force of the interlayer vibration damper 400 'installed to contact the bottom surface of the finishing mortar 200' and the top surface of the floor slab 100 '. Due to the insulation and sound absorption, there is a problem in that the heavy impact sound in which the sound insulation effect is determined in the low frequency band is not properly absorbed.

본 발명의 목적은 건축물의 바닥슬라브와 기포콘크리트 사이에서 경량 및 중량 진동을 효과적으로 절연시킴과 동시에 폭넓게 음압을 흡수하여, 상측 바닥의 충격에 의한 소음이 바닥슬라브를 통해 직하층으로 전달되는 현상이 방지되도록 하는 건축물의 층간바닥 충격음 차단구조를 제공하는 데 있다.An object of the present invention is to effectively insulate the light weight and heavy weight vibration between the floor slab and foam concrete of the building and to absorb sound pressure in a wide range, thereby preventing the noise caused by the impact of the upper floor from being transferred to the lower floor through the floor slab. It is to provide an interlayer floor shock sound blocking structure of the building.

이러한 본 발명의 목적은, 건축물의 콘크리트구조물로 타설되는 바닥슬라브(100)의 상부면에 러버재와 같이 자체탄성력을 갖고있는 하부층간방진재(400)가 소정의 간격을 두고 복수개 설치되고, 상기 하부층간방진재(400)의 상부에는 외측부 에 공명실(700)이 형성되도록 판재형상인 합판(600)이 놓여지며, 상기 합판(600)의 상부면에는 보조공명실(520)이 형성되도록 러버재와 같이 자체탄성력을 갖고있는 상부층간방진재(500)가 설치되며, 상기 상부층간방진재(500)에는 온돌마루등과 같은 마감재(300)가 상부면에 시공되는 마감몰탈(200)이 시공되는 것에 의해 달성된다.An object of the present invention, a plurality of lower interlayer dustproof material 400 having a self-elastic force, such as a rubber material on the upper surface of the floor slab 100 is poured into a concrete structure of the building at predetermined intervals, the lower portion, The plywood 600 is formed in a plate shape so that the resonance chamber 700 is formed on the outer side of the interlayer dustproof material 400, and the rubber material and the auxiliary resonance chamber 520 are formed on the upper surface of the plywood 600. The upper interlayer dustproof material 500 having its own elasticity is installed, and the upper interlayer dustproof material 500 is achieved by constructing a finishing mortar 200 in which a finishing material 300 such as an ondol floor is constructed on the upper surface. do.

따라서, 건축물의 직상층 바닥에 충격이 가해지는 경우, 상부층간방진재(500)와 한판(600) 및 하부층간방진재(400)에 의해 순차적으로 진동이 절연됨과 동시에 폭넓게 음압이 흡수되도록 함으로서, 상기 건축물의 직상층에서 발생된 충격음이 바닥슬라브(100)를 통해 직하층부로 전달되는 것이 방지되게 되는 것이다.Therefore, when an impact is applied to the floor of the upper floor of the building, the vibration is sequentially insulated by the upper interlayer dustproof material 500, the baffle plate 600, and the lower interlayer dustproof material 400, and at the same time, the sound pressure is broadly absorbed. Impact sound generated in the immediate upper layer of the floor slab 100 is to be prevented from being transmitted to the lower layer.

이하 첨부된 도면에 의하여 본 발명의 그 기술적 구성을 상세히 설명하면 다음과 같다. Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.

도 2는 본 발명에 따른 건축물의 층간바닥 충격음 차단구조를 보인 단면도 이다.Figure 2 is a cross-sectional view showing the structure of the impact floor interlayer of the building according to the invention.

본 발명의 건축물의 층간바닥 충격음 차단구조는 도 2에 도시하고 있는 바와 같이, 건축물의 콘크리트구조물로 타설되는 바닥슬라브(100)의 상부면에 러버재와 같이 자체탄성력을 갖고있는 하부층간방진재(400)가 소정의 간격을 두고 복수개 설치되고, 상기 하부층간방진재(400)의 상부에는 외측부에 진공의 공명실(700)이 형성되도록 판재형상인 합판(600)이 놓여지며, 상기 합판(600)의 상부면에는 보조공명실(520)이 형성되도록 러버재와 같이 자체탄성력을 갖고있는 상부층간방진재(500)가 설치되며, 상기 상부층간방진재(500)에는 온돌마루등과 같은 마감재(300) 가 상부면에 시공되는 마감몰탈(200)이 시공되는 것에 의해 달성된다.As shown in FIG. 2, the interlayer floor impact sound blocking structure of the building according to the present invention has a lower interlayer dustproof material 400 having self-elasticity as a rubber material on the upper surface of the floor slab 100 that is poured into the concrete structure of the building. A plurality of) are installed at predetermined intervals, and a plywood 600 having a plate shape is placed on the outer side of the lower interlayer dustproof material 400 so that a vacuum resonance chamber 700 is formed at an outer side thereof. On the upper surface, an upper interlayer dustproof material 500 having self-elasticity, such as a rubber material, is installed to form an auxiliary resonance chamber 520, and the upper interlayer dustproof material 500 includes a finishing material 300 such as an ondol floor. Finishing mortar 200 which is constructed on the surface is achieved by the construction.

한편, 상기 하부층간방진재(400)에는 합판(600)을 통해 전달되는 고체 전달음을 굴곡파로 전환시켜 투과 손실이 증가되도록 하는 상부요홈(410)과, 상기 상부요홈(410)을 통해 진동과 소음이 저감된 충격음이 하부로 전달되는 경우 음압을 감소시키는 공기층이 형성되도록 하는 하부요홈(420)이 상하부에 각각 형성됨을 밝혀 둔다.On the other hand, the lower interlayer dustproof material 400, the upper groove 410 and the upper groove 410 and the upper groove 410 to increase the transmission loss by converting the solid transmission sound transmitted through the plywood 600 to the bending wave, the vibration and noise It is noted that the lower recesses 420 are formed in the upper and lower portions, respectively, so that the air layer for reducing the sound pressure is formed when the reduced impact sound is transmitted downward.

또한, 상기 상부층간방진재(500)의 저면에는 하부로 돌출되는 돌기부(510)가 소정의 간격을 두고 복 수개 형성되어 있어, 상기 상부층간방진재(500)를 합판(600)에 올려놓는 것에 의해 상부층간방진재(500)와 합판(600) 사이에 보조공명실(520)이 형성되게 되는 것이다.In addition, a plurality of protrusions 510 protruding downward are formed on the bottom surface of the upper interlayer dustproof material 500, and the upper portion is placed on the plywood 600 by placing the upper interlayer dustproof material 500 on the plywood 600. The auxiliary resonance chamber 520 is formed between the interlayer dustproof material 500 and the plywood 600.

한편, 상기 상부층간방진재(500)의 저면에 하부로 돌출되게 형성되어 있는 돌기부(510)와 돌기부(510) 사이에는, 도 3에 도시하고 있는 바와 같이, 상기 돌기부(510) 보다 길이가 짧은 보조돌기(530)를 형성하여, 상기 상부층간방지재(500)에 충격 소음과 진동이 전달되면, 상기 충격 소음이 돌기부(510)와 돌기부(510) 사이의 보조공명실(520)에서 강약 강약으로 반복되어 흐르면서 가진음이 효과적으로 감쇄되도록 함이 더욱 바람직함을 밝혀 둔다.On the other hand, between the protrusion 510 and the protrusion 510 which is formed to protrude downward on the bottom surface of the upper interlayer dustproof material 500, as shown in Figure 3, the auxiliary shorter than the protrusion 510 When the projection 530 is formed, and impact noise and vibration are transmitted to the upper interlayer preventing material 500, the impact noise is weak and weak in the auxiliary resonance chamber 520 between the protrusion 510 and the protrusion 510. It turns out that it is more preferable to make the attenuation effectively attenuate with repeated flow.

이와 같이 구성되는 본 발명은 건축물의 직상층 바닥에 물건등이 낙화되어 충격이 가해지는 것에 의해 충격 소음과 진동이 발생하게되면, 상기 충격 소음과 진동이 마감몰탈(200)을 통해 상부층간방진재(500)로 전달되어지게 된다.According to the present invention configured as described above, when impact noise and vibration are generated due to an impact being applied to the floor of an upper floor of a building by impact, the impact noise and vibration are interspersed with an upper layer dustproof material through the finishing mortar 200 ( 500).

이때, 상기 상부층간방진재(500)로 전달된 충격 진동은 1차적으로 상부층간 방진재(500)의 자체 탄성력에 의해 진동이 절연됨과 동시에 보조공명실(520)에서 음압이 흡수 및 분산되고, 상기 상부층간방진재(500)에서 흡수하고 남은 충격음과 진동은 하드 하면서도 소프트한 목재로 제조된 판재형상의 합판(600)으로 전달된다.At this time, the shock vibration transmitted to the upper interlayer dustproof material 500 is primarily the vibration is insulated by its own elastic force of the upper interlayer dustproof material 500 and at the same time the sound pressure is absorbed and dispersed in the auxiliary resonance room 520, the upper The impact sound and vibrations remaining after absorbed from the interlayer dustproof material 500 are transmitted to the plate-shaped plywood 600 made of hard and soft wood.

상기 상부층간방진재(500)에서 흡수하고 남은 진동과 충격음이 합판(600)으로 전달되면, 상기 합판(600)이 자체의 탄성력에 의해 재차 진동을 흡수함과 동시에 음압을 폭넓게 분산시키게 된다.When the remaining vibration and impact sound absorbed by the upper interlayer vibration damper 500 are transmitted to the plywood 600, the plywood 600 again absorbs the vibration by its elastic force and simultaneously distributes the sound pressure widely.

한편, 상기 중간방진재(600)에서 폭넓게 분산이 이루어짐과 동시에 재차 흡수가 이루어진 진동은 하부층간방진재(400)로 전달이 이루어지게 된다.On the other hand, while the dispersion is made widely in the intermediate dustproof material 600, the vibration is absorbed again is transmitted to the lower interlayer vibration damper (400).

이때, 하부층간방진재(400)로 전달이 이루어진 진동과 충격 소음은 최종적으로 상기 하부층간방진재(400)의 자체 탄성력에 의해 최종적으로 진동이 절연되고, 중간방진재에서 폭넓게 분산이 이루어지면서 전달된 음압은 진공의 공명실(700)에서 최종적으로 흡음이 이루어지게 된다. At this time, the vibration and impact noise that is transmitted to the lower interlayer vibration damper 400 is finally insulated by the elastic force of the lower interlayer dustproof member 400 finally, the sound pressure transmitted while being widely dispersed in the intermediate dustproof material Sound absorption is finally achieved in the resonance chamber 700 of the vacuum.

이러한 본 발명은, 저주파 대역에서 차음효과가 결정되는 중량 충격음은 물론, 경량충격음이 건축물의 직상층에서 발생하는 경우에도, 건축물의 바닥슬라브와 기포콘크리트 사이에서 경량 및 중량 진동이 순차적으로 절연됨과 동시에 폭넓게 음압이 분산 및 흡수되어, 상측 바닥의 충격에 의한 소음이 바닥슬라브를 통해 직하층으로 전달되는 현상이 방지된다.The present invention, as well as the weight impact sound is determined in the low frequency band, as well as light impact sound is generated in the upper floor of the building, light and weight vibration is sequentially insulated between the floor slab and foam concrete of the building The sound pressure is widely distributed and absorbed, and the noise caused by the impact of the upper floor is prevented from being transferred to the lower floor through the floor slab.
