공동주택의 바닥구조를 시공하는데 이용됨.Used to construct the floor structure of a multi-family house.
Description
본 발명은 개량된 공동주택 바닥구조에 관한 것으로, 더욱 자세하게는 공동주택에 있어서 상하층간의 소음 및 진동의 전달에 의한 충격음을 차폐하기 위한 공동주택 바닥구조에 관한 것이다.The present invention relates to an improved multi-family floor structure, and more particularly to a multi-family floor structure for shielding the impact sound by the transmission of noise and vibration between the upper and lower floors in the multi-family house.
공동주택에 있어서, 상하층간 소음 및 진동 전달의 문제를 해결하기 위한 여러 가지 종류의 소음 및 진동차폐재에 대한 개발이 이루어져 왔다. 이 중에서 주로 사용되고 있는 것은 폐타이어를 잘게 부순 칩을 접착제 등 결합재로 결합시켜판상의 기성재로 만든 제품, 혹은 폐타이어 칩과 결합재를 혼합한 슬러리를 현장에서 직접 타설하여 경화시킨 제품, 혹은 천연고무, 합성고무, 합성수지, 발포고무 등을 원료로 하여 만들어진 탄성을 가진 판상의 기성재 등이 있다. 이 외에도 발포폴리스티렌판 등이 사용되기도 하나, 이는 장기침하의 가능성이 높고, 충격소음 방지의 효과가 낮아 소음 및 진동 차폐재로서의 기능을 충분히 발휘하지 못하고 있다.In apartment buildings, various kinds of noise and vibration shielding materials have been developed to solve the problem of noise and vibration transmission between upper and lower floors. Among them, mainly used are products made of a plate-like material by combining chips with finely divided waste tires with an adhesive, or a product in which a slurry mixed with waste tire chips and a binder is directly poured on site and cured, or natural rubber , Synthetic rubber, synthetic resin, foamed rubber, and the like, and a plate-like material having elasticity made from raw materials. In addition, foamed polystyrene plates may also be used, but they have a high possibility of long-term settlement and have a low effect of preventing shock noise, thus failing to sufficiently function as noise and vibration shielding materials.
전술한 바와 같은 소음 및 진동차폐재를 공동주택에 적용하는 종래 기술로는 실용신안등록출원 95-34218호에 제시되어 있다. 즉, 실용신안등록출원 95-34218호에는 콘크리트 바닥 슬래브 위에 소음 및 진동차폐재를 설치하여 소음 및 진동차폐층을 형성하고, 그 상면에 경량기포콘크리트나 발포스티로폼으로 단열층을 설치한 후, 상기 단열층의 상면에 난방용 온수 파이프를 설치하고, 적정 두께로 온돌미장 몰탈을 타설하여 마감하는 시공법이 제시되어 있다.A conventional technique for applying the noise and vibration shielding material as described above to a multi-family house is disclosed in Utility Model Registration Application No. 95-34218. That is, Utility Model Registration Application No. 95-34218 installs a noise and vibration shielding layer on a concrete floor slab to form a noise and vibration shielding layer, and installs a heat insulating layer of lightweight foam concrete or foamed styrofoam on the upper surface of the thermal insulation layer. A construction method is proposed in which a hot water pipe for heating is installed on the upper surface, and the ondol plaster mortar is cast in the appropriate thickness and finished.
그런데, 이러한 종래의 방법을 공동주택 현장에 도입하여 시공해 본 결과, 여러 가지 문제점이 있는 것으로 나타났다.However, as a result of introducing such a conventional method into a multi-unit housing site, it was found that there are various problems.
첫째, 소음 및 진동차폐재를 콘크리트 슬래브와 밀착시켜 균일하게 시공하기가 매우 어렵다. 일반적으로, 소음 및 진동차폐재는 공장 생산된 두께 10∼30㎜의 판상재인데 반해, 콘크리트 슬래브는 시공상의 오차로 그 면이 고르지 못하여 소음 및 진동차폐재가 콘크리트 슬래브 면에 밀실하게 부착되기 어렵다. 이를 해결하기 위해서는 콘크리트 슬래브면에 모래를 깔아, 바닥면을 균일하게 하는 등의 선행작업이 필요하기 때문에, 경제성이 떨어지는 문제점이 있다. 한편, 폐타이어칩을 주요 재료로 하는 일부 제품은 폐타이어칩과 결합재를 현장에서 섞어서 슬래브면 위에 포설함으로써, 이러한 문제점이 개선되기는 하나, 이 경우 결합재로 사용되는 접착제의 유독가스로 인해 작업자가 작업하는데 곤란하고, 환경 문제를 유발하는 등의 문제점이 있다.First, it is very difficult to uniformly install the noise and vibration shielding material in close contact with the concrete slab. In general, the noise and vibration shielding material is a factory-produced plate material having a thickness of 10 to 30 mm, whereas the concrete slab is not uniformly adhered to the surface of the concrete slab due to construction errors. In order to solve this problem, since it is necessary to perform a preliminary work such as laying the sand on the concrete slab surface and making the bottom surface uniform, there is a problem in that the economic efficiency is poor. On the other hand, some products whose waste tire chips are the main material are mixed with waste tire chips and binders in the field and laid on the slab surface. However, this problem is improved. It is difficult to do so, and causes problems such as environmental problems.
둘째, 소음 및 진동차폐재를 시공한 상면에 경량기포콘크리트를 타설할 경우 콘크리트 바닥 슬래브 위에 경량기포콘크리트를 타설할 때보다 경량기포콘크리트층에 발생되는 균열의 길이가 200% 이상 증가하는 문제점이 있다. 이러한 균열의 증가는 온돌바닥구조 전체의 두께가 일정하게 정하여져 있는 경우, 소음 및 진동차폐층의 두께만큼 경량기포콘크리트층의 두께가 감소되기 때문에, 경량기포콘크리트층의 허용전단력 및 허용인장력이 감소되고, 이 상태에서 작업하중에 의한 변위에 의해 균열이 쉽게 발생하게 된다. 또, 차음 및 진동차폐재가 탄성재이기 때문에 상부의 작업하중에 의해 경량기포콘크리트층의 변형률 변화가 커지는 동시에 소음 및 진동차폐재가 바닥면의 슬래브 콘크리트와 밀실하게 부착되지 않아 작업하중 작용시 급격한 변위를 일으켜 균열이 발생하게 된다. 경량기포콘크리트층에 이렇게 많은 균열이 발생할 경우 온수 파이프 설치가 어려울 뿐만 아니라 온돌미장 몰탈 타설 후, 몰탈 마감면에 균열 발생을 유도하는 등의 문제점이 있다.Second, when the lightweight foam concrete is placed on the upper surface of the noise and vibration shielding material, the length of cracks generated in the lightweight foam concrete layer is increased by 200% or more than when the lightweight foam concrete is placed on the concrete floor slab. This increase in cracks reduces the thickness of the lightweight foamed concrete layer by the thickness of the noise and vibration shielding layer when the entire thickness of the underfloor structure is fixed, thus reducing the allowable shearing force and the tensile strength of the lightweight foamed concrete layer. In this state, cracking easily occurs due to displacement due to the working load. In addition, since the sound insulation and vibration shielding material are elastic materials, the strain change of the lightweight foam concrete layer increases due to the work load on the upper part, and the noise and vibration shielding material do not adhere tightly to the slab concrete on the floor surface, so that the sudden displacement during work load action This will cause cracks. If so many cracks occur in the lightweight foam concrete layer, it is not only difficult to install the hot water pipe, but also has problems such as inducing cracks on the mortar finishing surface after placing ondol plaster mortar.
한편, 이러한 문제를 해결하기 위해 경량기포콘크리트 대신 다른 단열재료를 사용하는 것을 생각할 수 있는데, 실용신안등록출원 95-34218호 및 95-34219호에서는 경량기포콘크리트 대신 발포폴리스티렌 보드를 사용하는 것을 제시하고 있다. 그러나, 발포폴리스티렌 보드는 정적변형율이 크기 때문에, 차음 및 진동차폐재를설치하고, 그 위에 발포폴리스티렌 보드를 단열재로 설치하는 공법은, 마감몰탈의 치명적인 장기침하를 가져오게 된다. 또 난방용 온수 파이프를 발포폴리스티렌 보드 위에 설치할 경우 내열성이 부족하여, 발포폴리스티렌 보드에 변형이 일어나게 되므로, 전혀 실효성이 없다. 단, 발포폴리스티렌 보드 대신 고급재로서, 높은 압축강도를 가진 압축발포폴리스티렌 보드를 사용할 수는 있으나, 이는 경제성면에서 현실성이 없어, 그 적용이 제한적일 수밖에 없으며, 내열성의 부분에서는 여전히 문제점이 내포되어 있다.On the other hand, in order to solve this problem, it is conceivable to use other insulating materials instead of lightweight foam concrete. In the Utility Model Registration Application Nos. 95-34218 and 95-34219, it is suggested to use foamed polystyrene board instead of lightweight foam concrete. have. However, since the foam polystyrene board has a high static strain rate, the method of installing the sound insulation and vibration shielding material and installing the foam polystyrene board as a heat insulating material thereon leads to a fatal long-term settlement of the mortar. In addition, when the heating hot water pipe is installed on the foamed polystyrene board, heat resistance is insufficient, so that deformation occurs in the foamed polystyrene board, and thus is not at all effective. However, as a premium material instead of the foamed polystyrene board, it is possible to use a compressed foamed polystyrene board having a high compressive strength, but this is not practical in terms of economics, its application is limited, and still has problems in the heat resistance part.
따라서, 본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위한 것으로, 본 발명의 목적은 소음 및 진동차폐층과 단열용 경량기포콘크리트층을 형성함에 있어, 소음 및 진동차폐 효과를 증진시키면서도 경량기포콘크리트층의 균열 문제로 인한 시공상의 하자를 방지할 수 있는 개량된 공동주택 바닥구조를 제공하는데 있다.Accordingly, the present invention is to solve the problems of the prior art as described above, an object of the present invention in forming a noise and vibration shielding layer and a lightweight foam concrete layer for thermal insulation, while improving the noise and vibration shielding effect, while lightweight foam The present invention provides an improved apartment building floor structure that can prevent construction defects caused by cracking problems in concrete layers.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도1은 본 발명에 따른 공동주택 바닥구조의 단면도로서, 도면에서 11은 바닥 슬래브, 12는 단열 및 채움층, 13은 소음 및 진동차폐층, 14는 난방용 온수배관, 15는 마감 몰탈층을 각각 나타낸다.1 is a cross-sectional view of a multi-floor floor structure according to the present invention, 11 is a floor slab, 12 is a heat insulation and filling layer, 13 is a noise and vibration shielding layer, 14 is a hot water pipe for heating, 15 is a finishing mortar layer Indicates.
본 발명에 따른 공동주택의 바닥구조는 도1에 도시된 바와 같이 콘크리트 바닥 슬래브(11)와, 상기 콘크리트 바닥 슬래브(11) 상에 일정 두께의 경량기포콘크리트를 타설하여 형성된 단열 및 채움층(12)과, 상기 단열 및 채움층(12) 상면에 형성되는 소음 및 진동차폐층(13)과, 상기 소음 및 진동차폐층(13) 상면에 배설되는 난방용 온수배관(14), 그리고, 일정 두께로 몰탈을 타설하여 형성된 마감층(15)을 포함한다.As shown in FIG. 1, the floor structure of the multi-family house according to the present invention is a concrete floor slab 11 and a heat insulation and filling layer 12 formed by pouring lightweight foam concrete having a predetermined thickness on the concrete floor slab 11. ), The noise and vibration shielding layer 13 formed on the top surface of the heat insulation and filling layer 12, the hot water piping 14 for heating disposed on the top surface of the noise and vibration shielding layer 13, and a predetermined thickness. And a finishing layer 15 formed by pouring mortar.
이러한 구조에서 본 발명에 따른 공동주택 바닥구조의 가장 바람직한 실시예로서, 경량기포콘크리트(12)는 타설 후 약 7일이 지난 다음의 압축강도가 약 3㎏/㎠ 이상이어야 하며, 소음 및 진동차폐층(13)은 스프링 상수가 약 1,500∼10,000㎏/㎜/㎡, 정적압축변형율이 약 3% 이하의 물성을 가진 타이어칩 또는 합성고무를 주요 재료로 하여 제조된 것이다. 한편, 상기 소음 및 진동차폐재에 그 원료의 일부로서 황토미분, 황동 미분 등이 첨가될 수 있다. 그리고, 마감몰탈(15)은 타설 후 약 28일정도 지난 다음의 압축강도가 약 140㎏/㎠ 이상이어야 한다.As the most preferred embodiment of the multi-floor floor structure according to the present invention in this structure, the lightweight foam concrete 12 has to have a compressive strength of about 3 kg / ㎠ or more after about 7 days after pouring, shielding noise and vibration The layer 13 is made of a tire chip or synthetic rubber having a spring constant of about 1,500 to 10,000 kg / mm / m 2 and a static compressive strain of about 3% or less as a main material. On the other hand, ocher fine powder, brass fine powder, etc. may be added to the noise and vibration shielding material as part of the raw material. And, the finishing mortar 15 should be about 140kg / ㎠ or more after about 28 days after pouring.
이와 같이 본 발명에서는 타설 후 7일이 지난 다음의 압축강도가 약 3㎏/㎠이상이 되는 경량기포콘크리트를 사용함으로써, 일반적으로 경량기포콘크리트 타설후 약 5일 후에 진행되는 후속 작업에 의한 작업 하중에 의해 경량기포콘크리트층의 지압파괴, 펀칭파괴, 인장파괴 등이 일어나지 않도록 하여 균열 발생의 가능성을 최소화 하였다.As described above, in the present invention, by using lightweight foamed concrete having a compressive strength of about 3 kg / cm 2 or more after 7 days after pouring, the work load by subsequent work that is generally performed about 5 days after the lightweight foamed concrete is poured. By minimizing the pressure breakdown, punching breakdown, and tensile breakdown of the lightweight foam concrete layer, the possibility of cracking is minimized.
그런데, 전술한 바와 같은 본 발명에 따른 바닥구조는 마감몰탈의 내부에 발생하는 응력이, 경량기포콘크리트층 위에 시공되는 경우보다 더 커져서 마감 몰탈에 균열이 발생할 가능성이 높아지게 된다. 따라서, 본 출원인은 이러한 문제를 해결하기 위해 소음 및 진동차폐층에 대한 적절한 스프링 상수 및 정적 압축 변형율을 제한하여, 마감 몰탈층에 균열이 발생되거나 부분적인 침하가 일어나는 것을 방지하였다. 본 출원인의 연구 결과에 따르면 소음 및 진동차폐 성능과 구조적 안전성을 모두 고려한 적정한 스프링 상수는 약 1,500∼5,000㎏/㎜/㎡, 정적압축변형율은 3% 이하로서, 이와 같은 특성을 갖는 재료를 사용하여 소음 및 진동차폐층을 형성하는 것이 바람직하며, 암면, 발포폴리스티렌, 글라스울 등의 재료는 본 발명에 적용되는 소음 및 진동차폐재로서 적합하지 않는 것으로 나타났다.However, in the floor structure according to the present invention as described above, the stress generated in the interior of the finishing mortar is greater than when the construction on the lightweight foam concrete layer is likely to cause cracks in the finishing mortar. Therefore, Applicant limited the appropriate spring constant and static compressive strain for the noise and vibration shielding layer to solve this problem, to prevent cracking or partial settlement of the finishing mortar layer. According to the results of the applicant's research, the proper spring constant considering both noise and vibration shielding performance and structural safety is about 1,500∼5,000㎏ / ㎜ / ㎡, and the static compressive strain is 3% or less. It is preferable to form a noise and vibration shielding layer, and materials such as rock wool, expanded polystyrene, glass wool, etc. have been found to be unsuitable as noise and vibration shielding materials applied to the present invention.
또한, 본 발명에 따른 소음 및 진동차폐층에 접하여 난방용 온수배관을 설치함에 있어, 소음 및 진동차폐층에 황토 등의 물질을 첨가하면 열원에 가까이 접하게 되므로 원적외선이 방사되는 효과를 극대화할 수 있다.In addition, in installing the hot water pipe for heating in contact with the noise and vibration shielding layer according to the present invention, by adding a material such as ocher to the noise and vibration shielding layer can be in close contact with the heat source can maximize the effect of the far infrared radiation.
한편, 본 발명에 따른 실시예에서는 소음 및 진동차폐재로서, 천연고무, 합성고무, 합성수지 혹은 발포고무 등을 원료로 하여 만들어진 판상의 기성재, 혹은 폐타이어의 칩을 접착제 등의 결합재와 혼합하여 만든 판상의 기성재, 혹은 폐타이어의 칩과 접착제 등의 결합재를 현장에서 혼합하여 일정 두께로 포설한 형태를 가질 수 있다.On the other hand, in the embodiment according to the present invention as a noise and vibration shielding material, a plate-like base material made of natural rubber, synthetic rubber, synthetic resin or foamed rubber or the like, or waste tire chips made by mixing with a binder such as adhesive A plate-like ready-made material, or a binder and a bonding material such as chips and adhesives of waste tires may be mixed in the field and laid in a predetermined thickness.
또한, 본 발명에서는 이와 같이 소음 및 진동차폐층을 설치한 다음에, 그 상면에 염화비닐 시트 또는 이에 준하는 합성수지층을 깔고, 그 상면에 난방용 온수배관 설치한 다음, 마감 몰탈로 바닥을 마감할 수 있다.In addition, in the present invention, after installing the noise and vibration shielding layer, the vinyl chloride sheet or the corresponding synthetic resin layer is laid on the upper surface, and the hot water pipe for heating is installed on the upper surface, and then the floor can be finished by finishing mortar. have.
상기와 같이 이루어지는 본 발명에 의하면, 소음 및 진동차폐재가 콘크리트 바닥 슬래브와 경량기포콘크리트 사이에 설치된 종래 기술이 갖는 문제점인 경량기포콘크리트에 균열이 발생되는 문제점을 현저히 감소시켜, 균열에 의한 문제를 근본적으로 해결할 수 있으며, 또한 경량기포콘크리트가 타설된 상면은 경량기포콘크리트의 셀프레벨링성으로 인해 매끄러운 표면을 형성하게 되므로, 소음 및 진동차폐재가 밀실하게 부착될 수 있는 좋은 조건이 되어, 기존의 소음 및 진동차폐층의 설치를 위해 콘크리트 바닥면을 정리하던 시간과 비용을 현저하게 줄일 수 있고, 소음 및 진동차폐성능을 극대화할 수 있다. 더욱이 이와 같은 본 발명의 구조는 음원에서부터 소음 및 진동차폐층까지의 거리가 짧아지게 되므로, 진동에 의한 소음의 방지에 특히 유리하다.According to the present invention made as described above, the noise and vibration shielding material significantly reduces the problem of cracking in the lightweight foam concrete, which is a problem with the prior art installed between the concrete floor slab and lightweight foam concrete, fundamentally solve the problem caused by cracking In addition, the upper surface on which the lightweight foam concrete is poured forms a smooth surface due to the self-leveling property of the lightweight foam concrete, so it is a good condition for the noise and vibration shielding material to be tightly attached. It can significantly reduce the time and cost of cleaning the concrete floor for the installation of the vibration shielding layer, and maximize the noise and vibration shielding performance. Moreover, since the distance from the sound source to the noise and vibration shielding layer is shortened, the structure of the present invention is particularly advantageous in preventing noise caused by vibration.
