본 발명은 공동주택의 층간바닥을 시공하는 과정에서 층간 충격음을 차폐하는 층간차음재에 관한 것으로서, 더욱 상세하게는, 층간차음재를 서로 다른 비중을 갖는 2개의 발포성 스티로폼을 적층하여 구성하되, 상기 2개의 스티로폼 사이에 차음 홈들을 형성하고, 바닥면에 돌기 또는 홈 등의 차음구조를 마련하여 소음이나 충격음이 아래층으로 전달되는 것을 최소화할 수 있는 건물의 층간차음재 및 그 제조방법에 관한 것이다.The present invention relates to an interlayer sound insulation material for shielding an interlayer impact sound in the process of constructing an interlayer floor of a multi-unit house. More specifically, the interlayer sound insulation material is configured by stacking two foamed styrofoams having different specific gravity. The present invention relates to an interlayer sound insulation material of a building and a method of manufacturing the same, which may form sound insulation grooves between styrofoam and provide sound insulation structures such as protrusions or grooves on the floor to minimize noise and impact sound from being transferred to the lower floor.

아파트나 빌라 등 공동주택의 건물 구조체에 가해지는 충격음은 사람의 보행, 문의 개폐, 기물의 이동이나 설비기기의 가동 혹은 정지 등이 충격의 원인이 되어 발생되는 고체전달음이 사방으로 전달되게 되고, 이로 인하여 건물구조체의 표면을 진동시킴은 물론 공기전달음으로 전환되어 주변의 사람들 귀에 들리게 될 때, 소음으로 인식되게 된다. The impact sound that is applied to the building structure of apartment buildings such as apartments and villas is transmitted by solid propagation sound generated by people walking, opening and closing doors, moving objects, starting or stopping equipment, etc. As a result, the surface of the building structure is not only vibrated, but also converted into air transmission sound, which is recognized as noise when it is heard in the surrounding people's ears.

예를 들어, 물건의 낙하 등의 충격이 바닥에 가해지거나 의자를 옮기는 소리 등은 고체전달음을 발생시키고 이 고체전달음은 바닥슬래브와 벽체를 통해 인접한 다른 방들로 전달되되 특히 바닥슬래브를 통해 아래층에 전달되는 것을 층간소음이라 한다. 요즘에는 이러한 층간소음문제가 공동주택에서 심각하게 대두됨에 따라 주택건설기준 등에 관한 규정이 더욱 강화 개정되기에 이르렀다. 상기 규정에는 각 층간의 바닥충격음이 경량충격음은 58데시벨(dB)이하이어야 하고, 중량충격음은 50데시벨(dB)이하이거나 건설교통부장관이 정하여 고시하는 표준바닥구조로 하여야 한다고 명시되어 있다. For example, the impact of falling objects on the floor or the sound of moving a chair generates solid sound, which is transmitted through the floor slab and the walls to other adjacent rooms, especially through the floor slab. This is called interlayer noise. Nowadays, as such inter-floor noise problem is seriously raised in multi-unit houses, regulations on housing construction standards have been strengthened and revised. The regulations stipulate that the floor impact sound between floors should be less than 58 decibels (dB) and the weight impact sound should be less than 50 decibels (dB) or standard floor structure as determined and announced by the Minister of Construction and Transportation.

이와 같이 심각하게 대두되는 층간소음을 줄여 최소화하기 위한 통상적인 층간 바닥구조 들이 제시되어 있는데, 이러한 기존의 통상적인 층간 바닥구조는, 도 1에 도시된 바와 같이 콘크리트슬래브(1)를 기준으로 상부에 경량기포 콘크리트층(2)이 형성되고, 그 상단으로 난방용 배관(3)과 마감용 몰탈층(4)이 형성되며, 그 위에 모노륨이나 원목, 타일 등의 장식재로 된 바닥장식층(5)으로 구성된다.Conventional interlayer floor structures for minimizing and minimizing such a serious noise between floors have been proposed. Such conventional interlayer floor structures are shown on top of the concrete slab 1 as shown in FIG. Lightweight foam concrete layer (2) is formed, the heating pipe (3) and the finishing mortar layer (4) is formed on the upper side, on the floor decorative layer (5) made of decorative materials such as monolium, wood, tiles, etc. It is composed.

상기한 구조의 층간바닥구조는 콘크리트 슬래브(1) 상부에 형성된 경량기포 콘크리트층(2)이 충격음이나 소음을 감쇄시키는 작용을 담당하고 있으나, 그 효과가 미미한 실정이다.The interlayer floor structure of the above structure is a lightweight foam concrete layer (2) formed on the concrete slab (1) is responsible for attenuating the impact sound or noise, but the effect is insignificant.

이로 인해 보다 효과적으로 소음이나 충격을 차단하기 위하여, 상기 콘크리트 슬래브와 경량기포콘크리트 사이에 층간충격음 완충재를 형성하는 시공방법이 개시되어 있다.For this reason, in order to more effectively block noise and impact, a construction method for forming an interlayer shock-absorbing material between the concrete slab and lightweight foamed concrete is disclosed.

In the apartment house floor structure including a noise and vibration shielding layer respectively installed on the wall, the noise and vibration shielding layer of the floor includes at least two or more noise and vibration shielding material having a plurality of protrusions on one side, the noise and vibration shielding material At least one air layer is formed on the noise and vibration shielding layer by stacking them together, and further comprising a plastic cap covering the noise and vibration shielding material of the wall, so that the finishing mortar layer coincides with the upper surface of the plastic cap. It is characterized by being poured.

다른 예로서, 등록실용신안공보 등록번호 제20-315852호에 '층간충격음 완충재용 스티로폼'이 안출된 바 있으며, 이는 하나의 스티로폼 내에 수평방향으로 폐쇄된 셀들을 갖는 저밀도 조직부와 연속된 셀층을 갖는 고밀도 조직부가 형성된 것과, 상기 저밀도 조직부들이 서로 연결되지 않으면서 저밀도 조직부와 고밀도 조직부의 표면적 비율이 1:0.3 내지 1:4 인 것과, 상기 저밀도 조직부가 외측으로 돌출된 돌출부를 갖는 것을 특징으로 하고 있다.As another example, 'Styrofoam for interlayer shock sound absorbing material' has been devised in Korean Utility Model Publication No. 20-315852, which has a continuous cell layer and a low density tissue having horizontally closed cells in one styrofoam. It is characterized in that the high density tissue portion is formed, the low density tissue portion is not connected to each other, the ratio of the surface area of the low density tissue portion and the high density tissue portion is 1: 0.3 to 1: 4, and the low density tissue portion has a protrusion projecting outwardly. .

또 다른 예로서, 등록실용신안공보 등록번호 제20-342633호에 '건물의 층간 단열 및 소음저감재'가 안출된 바 있으며, 이는, 일측면에 일정패턴으로 다수개의 오목부가 형성되고 적어도 하나의 모서리에 암연결부가 형성되는 A-판상체와, 상기 A-판상체와 짝을 이루도록 적어도 하나의 모서리에 수연결부가 형성되고 일측면에 일정패턴으로 다수개의 오목부가 형성되는 B-판상체로 이루어지고, 상기 각 A-판상체와 B-판상체의 오목부가 건물의 바닥슬래브와 마주하도록 그 암연결부와 수연결부가 맞물려 일정면적의 바닥슬래브 상에 설치되는 것을 특징으로 하고 있다.As another example, 'Interlayer insulation and noise reduction materials of buildings' were laid out in Korean Utility Model Registration No. 20-342633, which has a plurality of recesses formed in a predetermined pattern on one side and at least one An A-plate body having a female connection portion formed at an edge, and a B-plate body having a male connection portion formed at at least one corner so as to mate with the A-plate structure and having a plurality of recesses formed in a predetermined pattern on one side thereof. It is characterized in that the female connecting portion and the male connecting portion are installed on the floor slab of a predetermined area so that the recesses of the respective A-plate and B-plate bodies face the floor slab of the building.

전술한 종래 기술들은, 모두 층간소음을 차단하기 위해 건물의 바닥슬래브 상단에 별도의 소음차단재를 구성하고 있으나, 상기 층간의 소음차단재들의 소재가 서로 다르고 고가의 것이며 그 소재들이 비교적 하드(hard) 또는 소프트한 것으로 중량충격음과 경량충격음 중의 어느 하나의 음을 차폐하는 것일 뿐이어서 경량충격 음과 중량충격음 모두를 유효적절하게 층간소음을 차폐하지 못한다는 문제점이 있었다.The above-mentioned prior arts all constitute a separate noise blocking material on the top of the floor slab of the building to block the noise between floors, but the materials of the noise blocking materials between the floors are different and expensive and the materials are relatively hard or As a soft thing, it merely shields one of the heavy shock sound and the light impact sound, and thus there is a problem in that the light impact sound and the heavy shock sound cannot effectively shield the interlayer noise.

또한, 상기 층간소음재를 제조함에 있어서, 그 구조가 단순하지 못하고 복잡하여 생산단가는 물론 시공비의 증대를 가져오는 등의 문제점이 있었다.In addition, in manufacturing the interlayer noise absorbing material, the structure is not simple and complicated, there are problems such as production cost and increase in construction cost.

상기와 같은 특징으로 이루어진 본 발명인 건물의 층간차음재 및 그 제조방법은, 건물의 바닥슬래브에 설치하는 층간차음재의 제조가 간단한 구성에 의해 이 루어짐에 따라 생산단가의 절감을 유도할 수 있고, 층간차음재의 바닥면에 형성된 완충차음구조는 물론, 층간차음재를 구성하는 제1부재와 제2부재의 접합면에 형성된 차음 홈들에 의해 층간소음을 최소화시킬 수 있음으로써 하층에 거주하는 거주자들에게 심한 소음에 의한 스트레스를 줄이거나 미연에 방지할 수 있다.According to the present invention, the building's interlayer sound insulating material and the method of manufacturing the same according to the present invention can lead to a reduction in production cost as the manufacturing of the interlayer sound insulating material installed on the floor slab of the building is made by a simple configuration. The sound insulation structure formed on the bottom surface of the sound insulation material, as well as the sound insulation grooves formed in the joining surface of the first member and the second member constituting the interlayer sound insulation material can minimize the noise between floors so that the residents living in the lower floor It can reduce or prevent the stress caused by.

이하, 본 발명인 건물의 층간차음재 및 그 제조방법을 첨부된 도면에 의거하여 좀 더 구체적으로 설명한다.It will be described below in more detail on the basis of the accompanying drawings, the sound insulation material and the method of manufacturing the building of the present invention.

도 2는 본 발명인 건물의 층간차음재를 나타낸 사시도이고, 도 3은 본 발명에 따른 층간차음재의 구성을 나타낸 분해사시도이며, 도 4는 본 발명에 따른 층간차음재의 구성을 나타낸 단면도이다.Figure 2 is a perspective view showing the interlayer sound insulating material of the building of the present invention, Figure 3 is an exploded perspective view showing the configuration of the interlayer sound insulating material according to the present invention, Figure 4 is a cross-sectional view showing the configuration of the interlayer sound insulating material according to the present invention.

도시된 바와 같이, 본 발명에 따른 층간차음재는 경량 스티로폼으로 형성된 제1부재(10)와, 상기 제1부재(10)의 상면에 적층되어 접합되는 것으로 상기 제1부재(10)에 비하여 비중이 큰 중량 스티로폼 재질로 형성된 제2부재(20)로 이루어진다. 여기에서 경량 스티로폼이라 함은 단위체적당 5~12㎏/㎥인 것을 말하고, 중량스티로폼이라 함은 단위체적당 12~20㎏/㎥인 것을 말한다.As shown, the interlayer sound insulating material according to the present invention has a specific gravity compared to the first member 10 to be laminated and bonded to the first member 10 and the upper surface of the first member 10 formed of lightweight styrofoam. The second member 20 is formed of a large weight styrofoam material. Here, lightweight styrofoam refers to 5 to 12 kg / m3 per unit volume, and heavy styrofoam refers to 12 to 20 kg / m3 per unit volume.

상기 제1부재(10)는 그 바닥면(하면)에 완충차음구조인 완충차음 돌기(11)가 형성된다. 이 완충차음 돌기(11)는 하면에서 하측으로 일정한 높이만큼 돌출되고, 균등 간격으로 배열된다. 상기 제2부재(20)는 하면에 차음 홈(21)들이 일렬로 일정한 간격으로 형성된다.The first member 10 is formed on the bottom (lower surface) of the cushioning sound-proof projection 11 is a buffered soundproof structure. These shock absorbing and projecting protrusions 11 protrude downward from a lower surface by a constant height and are arranged at equal intervals. The second member 20 is formed at regular intervals on the lower surface of the sound insulating grooves 21 in a row.

상기 제1부재(10)의 바닥면에 균등간격으로 형성된 완충차음 구조인 완충차음 돌기(11)는 상기 제1부재(10)의 바닥면과 별도의 접착제를 이용하여 접합할 수 있고, 또는 발포성형기에서 성형시 상기 제1부재(10)의 바닥면으로부터 돌출되게 일체로 성형할 수도 있다.The buffer soundproof protrusion 11, which is a buffer soundproof structure formed at equal intervals on the bottom surface of the first member 10, may be bonded to the bottom surface of the first member 10 using a separate adhesive, or foamed When molding in a molding machine may be integrally molded to protrude from the bottom surface of the first member (10).

도 5는 본 발명에 따른 층간차음재의 다른 실시 예를 나타낸 사시도로서, 제1, 제2부재(10,20)의 접합면에 형성되는 차음 홈(21)을 일방향이 아닌 직교하는 형상, 즉 바둑판형상으로 마련한 것이다.5 is a perspective view showing another embodiment of the interlayer sound insulating material according to the present invention, in which the sound insulating grooves 21 formed on the joining surfaces of the first and second members 10 and 20 are not orthogonal in one direction, that is, a checkerboard. It is prepared in the form.

상기와 같이 층간차음재의 하면에 마련된 완충차음 돌기(11)는 물론 제1, 제2부재(10,20)의 접합부위에 차음 홈(21)이 서로 직교하는 바둑판형상으로 마련되므로 소음 및 충격음을 보다 효율적으로 흡수, 감쇄시키고, 이로 인하여 소음 및 충격음이 하층으로 전달되는 것을 최소화할 수 있는 것이다. 다시 말해서, 위와 같이 제1부재(10)와 제2부재(10,20)의 접합면에 차음 홈(21)을 형성한 경우에는 차음 홈이 없는 층간차음재를 시공한 경우에 비해 경량충격음과 중량충격음이 더욱 감쇠되게 되는 것이다. 상기 제1, 제2부재(10,20)의 접합면에 차음 홈(21)을 형성하되, 제2부재(20)의 너비 방향으로는 그 깊이를 3~5㎜로 낮게 형성하고, 제2부재(20)의 길이 방향으로는 그 깊이를 6~8㎜로 좀 더 깊게 형성하면 고체전달음으로부터 파생된 공기전달음을 교란에 의하여 보다 효과적으로 차음할 수 있으며, 차음 홈이 없는 층간차음재를 시공한 경우에 비하여 경량충격음과 중량충격음이 더욱 감쇠되게 되는 것이다. As described above, the sound insulating grooves 21 are formed in the shape of a checkerboard that is perpendicular to each other at the joint portions of the first and second members 10 and 20 as well as the buffer sound insulating protrusions 11 provided on the lower surface of the interlayer sound insulating material. It can be efficiently absorbed and attenuated, thereby minimizing the transmission of noise and impact sound to the lower layer. In other words, when the sound insulation grooves 21 are formed on the joint surfaces of the first member 10 and the second members 10 and 20 as described above, the impact impact and weight are lighter than when the interlayer sound insulation material without the sound insulation grooves is constructed. The impact sound is more attenuated. A sound insulating groove 21 is formed on the joining surfaces of the first and second members 10 and 20, but the depth of the second member 20 is lowered to 3 to 5 mm in the width direction of the second member 20. If the depth of the member 20 is formed deeper in the longitudinal direction of 6 to 8 mm, the air conduction derived from the solid transfer sound can be effectively sounded by disturbance, and the interlayer sound insulation material without the sound insulation groove is constructed. Compared to one case, the light impact sound and the heavy impact sound are more attenuated.

또한 상기 제2부재(20)의 상면에도 완충차음 구조를 마련할 수 있고 이 완충차음 구조는 도 6과 같이 제2부재(20)의 상면에 일정간격으로 차음 홈(23)이 서로 직교하는 형상, 즉 평면상 바둑판형상으로 마련할 수도 있다.In addition, a cushioning sound insulating structure may be provided on an upper surface of the second member 20. The buffering sound insulating structure has a shape in which the sound insulating grooves 23 are orthogonal to each other at regular intervals on the upper surface of the second member 20 as shown in FIG. That is, it can also provide in planar checkerboard shape.

특히, 도 7a 및 도 7b에 나타낸 바와 같이 제1, 제2부재(20)의 접합면인 제1부재(10)의 상면과 제2부재(20)의 하면에 각각 차음 홈(12,21)들이 형성되되 이 차음 홈(12,21)들은 서로 대응하여 각각 하나의 공통된 공간으로 형성되고, 상기 제1부재(10)의 하면에도 차음 홈(13)을 형성한 것이다.In particular, as shown in FIGS. 7A and 7B, the sound insulating grooves 12 and 21 are respectively formed on the upper surface of the first member 10 and the lower surface of the second member 20, which are joint surfaces of the first and second members 20, respectively. The sound insulating grooves 12 and 21 are formed in one common space corresponding to each other, and the sound insulating grooves 13 are formed on the lower surface of the first member 10.

상기와 같이 구성된 층간차음재에 의하면, 제2부재(20)의 하면에만 차음 홈(21)을 형성한 경우보다 제1, 제2부재(10,20)의 접합양면에 통합된 하나의 차음 홈(A)으로 형성한 경우 경량충격음과 중량충격음이 보다 더 떨어지고, 여기에 제1부재(10)의 하면에도 차음 홈(13)이 형성되었을 때 경량충격음과 중량충격음이 좀 더 떨어지게 되는 것이다. 상기 차음 홈들은 상기에서 언급하였듯이 그 깊이를 달리하면 고체전달음과 공기전달음을 효과적으로 교란시켜 상쇄시키므로 보다 향상된 차음이 이뤄지게 된다.According to the interlayer sound insulation material configured as described above, one sound insulation groove integrated into both joining surfaces of the first and second members 10 and 20 than the sound insulation groove 21 is formed only on the bottom surface of the second member 20 ( A) is formed when the light impact sound and heavy impact sound is further dropped, and when the sound insulation groove 13 is formed on the lower surface of the first member 10, the light impact sound and heavy impact sound are further dropped. As mentioned above, the sound insulation grooves have different depths, effectively disturbing and canceling the sound transmission sound and the air transmission sound, thereby improving sound insulation.

상기와 같이 구성된 본 발명에 따른 건물의 층간차음재 제조방법은, 도 8에 나타낸 바와 같이, 경량의 스티로폼의 제1부재(10) 하면에 균등간격으로 차음 홈(12)들을 형성하고, 상기 제1부재(10)에 비해 비중이 큰 중량의 스티로폼인 제2부재(20)의 하면에 균등간격으로 차음 홈(21)들을 형성한 다음, 상기 제1부재(10)의 상면에 상기 제2부재(20)의 차음 홈(21)들이 형성된 하면을 서로 접합하여 적층하고, 상기 적층단계에 의해 서로 적층된 제1부재(10)와 제2부재(10)를 소정압력으로 가압하면서 건조하여 마무리한다.In the method of manufacturing an interlayer sound insulation material of a building according to the present invention configured as described above, as shown in FIG. 8, the sound insulation grooves 12 are formed at equal intervals on the lower surface of the first member 10 of the lightweight styrofoam, and the first Sound insulating grooves 21 are formed on the lower surface of the second member 20, which is a styrofoam having a greater specific gravity than the member 10, at equal intervals, and then the second member () is formed on the upper surface of the first member 10. The lower surfaces of the sound insulation grooves 21 of 20 are bonded to each other and laminated, and the first and second members 10 and 10 stacked on each other by the lamination step are dried and pressed to a predetermined pressure.

상기에서 제1부재(10)를 마련할 때, 제1부재(10)의 바닥면에는 균등간격으로 완충차음 돌기(11)를 형성하거나 부착하는 단계가 더 부가될 수 있다.When the first member 10 is provided in the above, the bottom surface of the first member 10 may be further added to form or attach the shock absorbing projections 11 at equal intervals.

상기 제조과정에서 제1부재(10)의 차음 홈(12,13)과, 제2부재(20)의 차음 홈 (21)은, 시트상의 제1, 제2부재(10,20)를 마련하고 그 상면에 등 간격으로 배열된 다수의 열선을 이용하여 형성하거나 발포시킨 비드를 발포성형기의 금형에 의해 마련할 수 있는 것이다.In the manufacturing process, the sound insulating grooves 12 and 13 of the first member 10 and the sound insulating grooves 21 of the second member 20 are provided with sheet-shaped first and second members 10 and 20. Beads formed or foamed using a plurality of hot wires arranged at equal intervals on the upper surface thereof can be provided by a mold of a foam molding machine.

상기 제1, 제2부재(10,20)에 형성되는 차음 홈의 깊이는, 대략 4㎜~8㎜ 정도로 형성하는 것이 바람직하다. 상기 차음 홈을 제1, 제2부재(10,20)의 접합양면에 형성하는 경우, 깊이가 4㎜ 이하일 경우엔 제1, 제2부재(10,20)의 한쪽에 가공되는 홈 깊이가 2㎜이하로 너무 낮아 열선으로의 가공이 곤란하고, 8㎜ 이상일 경우엔 제1, 제2부재(10,20)의 두께에 비해 차음 홈이 상대적으로 너무 커서 구조적으로 강도가 취약해질 수 있기 때문이다.The depth of the sound insulating grooves formed in the first and second members 10 and 20 is preferably about 4 mm to 8 mm. When the sound insulating groove is formed on both surfaces of the first and second members 10 and 20 to be joined, when the depth is 4 mm or less, the groove depth to be processed on one side of the first and second members 10 and 20 is 2 This is because the processing of the heating wire is difficult because the thickness is less than ㎜, and when the thickness is 8 mm or more, the sound insulation grooves are relatively too large compared to the thicknesses of the first and second members 10 and 20, and thus the structural strength may be weak. .

또한 상기 제1, 제2부재(10,20)는 위와 같이 차음 홈(12,21)을 마련하고 제1부재(10)의 완충차음 돌기(11)를 마련하는 것을 별도의 공정으로 수행하는 것으로 설명하였으나 발포비드를 소정배율로 발포 성형하는 발포성형기의 금형에 형성하여 발포성형과 동시에 수행할 수도 있다.In addition, the first and second members 10 and 20 are to provide the sound insulating grooves 12 and 21 as described above, and to provide the cushioning and insulating protrusions 11 of the first member 10 in a separate process. Although described, the foam beads may be formed in a mold of a foam molding machine for foam molding at a predetermined magnification, and may be performed simultaneously with foam molding.

본 발명에 따른 건물의 층간차음재는, 제1부재(10)와 제2부재(20)를 적층하여 이들을 서로 접합한 후 작업현장에서 바로 사용하여도 무방하고, 또한 제1부재(10)와 제2부재(20)를 각각 구비하여 작업현장에서 바닥슬래브 상단에 상기 제1부재(10)를 깔은 후, 제1부재(10)의 상면에 제2부재(20)를 적층시켜도 무방하다.The sound insulation material of the building according to the present invention may be used directly at the work site after laminating the first member 10 and the second member 20 and bonding them together, and further, the first member 10 and the first member 10 may be used. Two members 20 may be provided, respectively, and the second member 20 may be stacked on the upper surface of the first member 10 after the first member 10 is laid on the floor slab at the work site.

상기와 같이 바닥슬래브의 상면에 본 발명인 건물의 층간차음재를 시공할 경우, 층간차음재를 구성하는 제1부재(10)의 바닥에 균등간격으로 형성된 완충차음 돌기(11)에 의해 층간차음재의 바닥 전체가 바닥슬래브에 접하지 않고 일부가 뜬 상태로 시공되기 때문에, 물건이 떨어졌을 때의 충격음이나 또는 아이들이 뛸 때의 소음 등이 바닥슬래브에 바로 전달되지 않음으로써 하층에 소음이 전달되는 것이 최소한 줄어들게 된다.When the interlayer sound insulation material of the building of the present invention is installed on the upper surface of the floor slab as described above, the entire floor of the sound insulation material by the buffer sound insulating projection 11 formed at equal intervals on the bottom of the first member 10 constituting the interlayer sound insulation material. Since the construction is part of the floor slab without touching the floor slab, the impact noise when the object is dropped or the noise when the children run is not transmitted directly to the floor slab, thereby at least reducing the transmission of noise to the lower floor. .

더욱이, 상기 제1, 제2부재(10,20)의 하면에 형성된 차음 홈(13,21)과 제1, 제2부재(10,20)의 접합양면에 형성된 차음 홈(A)에 의해 충격음이나 소음이 분산 내지 소멸되는 효과를 얻을 수 있음에 따라, 하층에 전달되는 소음이 확실하게 줄어들어 최소화된다.Furthermore, the impact sound is caused by the sound insulation grooves A formed on both surfaces of the sound insulation grooves 13 and 21 formed on the bottom surfaces of the first and second members 10 and 20 and the first and second members 10 and 20. However, as the noise is dispersed or dissipated, the noise transmitted to the lower layer is surely reduced and minimized.

상기 차음 홈(12,21,23,A)의 형상은 상하로 긴 장방형으로 도시하고 설명하였으나, 이외에 반원형, 타원형, 사각형상 등의 다양한 형상으로 변형 실시할 수 있음은 당연하다 할 것이다.Although the shape of the sound insulation grooves 12, 21, 23, A is illustrated and described in a long rectangular shape up and down, it will be obvious that the shape of the sound insulating grooves 12, 21, 23, and A may be modified in various shapes such as semicircular, elliptical, and rectangular.

First, the same construction as the construction cross-sectional standards of the same layer noise prevention material as in the comparative example above, but only the change in the interlayer sound insulation material. The interlayer sound insulating material is bonded to the first member is a lightweight styrofoam having a weight of 8㎏ / ㎥ per unit volume of 1cm, and the second member is bonded with a weight of styrofoam having a thickness of 15㎏ / ㎥ per unit volume of 2cm, the bonding In the case where the sound insulation grooves are formed in the shape of a checkerboard only on the surface, in the case where the sound insulation grooves are formed in the form of a checkerboard on the lower surface of the first member, and the joint surface of the lightweight styrofoam and the heavy styrofoam, as well as the sound insulation grooves in the form of a checkerboard on the lower surface of the first member For the case of forming a light impact sound and a heavy impact sound was measured. At this time, the depth of the sound insulating groove was 7 mm in the longitudinal direction of the first and second members and 4 mm in the width direction.

상기 실시 예에서 알 수 있듯이, 제1부재 및 제2부재의 접합면에 제1, 제2차음 홈을 형성한 경우에는 단일의 경량 또는 중량스티로폼으로 된 층간차음재를 시 공한 경우에 비해 경량충격음과 중량충격음이 5~11dB 더 떨어지는 것을 알 수 있었다. 특히, 제1부재 및 제2부재의 접합면은 물론 바닥면에도 반원형의 차음 홈을 형성한 경우에는 제1부재 및 제2부재의 접합면에 차음 홈을 형성한 경우보다 경량충격음과 중량충격음이 2~9dB 더 떨어지는 것을 알 수 있었다. 결론적으로, 본 발명에 따른 층간차음재는 주택건설기준 등에 관한 규정에서 요구하는 경량충격음과 중량충격음 모두 규제치 이하로서 상기 규정에 적합한 것임을 알 수 있었다.As can be seen in the above embodiment, when the first and second sound insulating grooves are formed on the joining surfaces of the first member and the second member, a light impact sound and The weight shock sound was found to be 5 to 11 dB lower. In particular, when the semicircular sound insulation grooves are formed on the joining surfaces of the first member and the second member as well as the bottom surface, the light impact sound and the heavy impact sound are more than the case where the sound insulation grooves are formed on the joining surfaces of the first member and the second member. It can be seen that it is 2 ~ 9dB lower. In conclusion, it was found that the interlayer sound insulation material according to the present invention is suitable for the above regulations as both the light impact sound and the heavy impact sound required by the regulations on the housing construction standards and the like are below the regulation values.

상술한 바와 같이 본 발명인 건물의 층간차음재 및 그 제조방법에 의하면, 건물의 바닥슬래브에 설치하는 층간차음재의 제조가 간단한 구성에 의해 이루어짐에 따라 생산단가의 절감을 유도할 수 있고, 층간차음재의 바닥면에 형성된 완충차음 돌기라든가, 층간차음재를 구성하는 제1부재와 제2부재의 접합면에 형성된 차음 홈은 물론 제1부재 바닥면의 차음 홈들로 인해 층간소음이 확실하게 최소화되어 줄어들음으로써, 하층에 거주하는 거주자들에게 심한 소음에 의한 스트레스를 미연에 방지할 수 있는 효과가 기대된다.
아울러 제1부재와 제2부재의 접합면에 각각 형성된 차음 홈은 너비 방향과 서로 직교하는 길이 방향의 깊이가 상이한 바, 이에 따라 고체전달음과 공기전달음을 효과적으로 교란, 상쇄시켜 보다 향상된 차음효과를 기대할 수 있다는 이점이 있다.
