본 발명의 경량벽체는 흡음재 및 차음재인 경량기포콘크리트층의 일측면에 세라믹코팅 또는 방수코팅을 한 보드를 설치함으로써 2중의 소음흡수 및 완화작용을 하는 기능이 있으며, 시공이 용이하고 내구성을 유지할 수 있는 것에 관한 것이다. The lightweight wall of the present invention has a function of absorbing and mitigating double noise by installing a ceramic coated or waterproof coated board on one side of the light-absorbing material and the sound-absorbing material, which is a sound-absorbing material. It's about being.
오늘날, 우리의 일상생활 주변에는 각종 기계 설비의 가동과 자동차, 철도, 지하철, 항공기 등 교통수단의 운행, 그리고 중장비를 이용한 각종 공사, 또는 각 종 음향기기의 작동 등 여러 가지 요인에 의해 끊임없이 소음이 발생되고 있다. 따라서 소음 유발원들은 가능한 한 소음이 적게 발생되도록 설계되어야 하고, 불가피하게 소음이 발생될 경우 그 소음이 외부로 전파되는 것을 최대한 차단할 필요가 있다.In today's world, noise is constantly generated by various factors such as the operation of various mechanical equipment, the operation of transportation means such as automobiles, railways, subways, and aircrafts, the construction of heavy equipment, and the operation of various acoustic devices. It is occurring. Therefore, noise sources should be designed to generate as little noise as possible, and if noise is inevitably generated, it is necessary to block the noise from spreading to the outside.
그리고 건축물은 화재 발생시 일정시간 성능을 유지하고 인명 대피와 보호를 위하여 내화 및 방화 성능을 요구한다. 특히, 사용자가 많거나 노약자들이 많은 집단시설, 공공시설, 양로원, 학원에서 화재발생시 인명구호에 어려움이 있다. In addition, the building maintains its performance for a certain time in the event of a fire and requires fire and fire protection for evacuation and protection. In particular, there are difficulties in lifesaving in case of fire in group facilities, public facilities, nursing homes, and academies with many users or the elderly.
한편, 생활습관의 변화로 실내에 활동하는 시간이 과거에 비해 증가된 지금 실내 공기질 관리는 밀폐된 실내생활에서 공기환경은 인체에 직접적 영향을 미치게 되어 빌딩증후군, 화학물질과민증, 새집증후군을 양산하게 되었다. In the meantime, indoor air quality management has increased compared to the past due to changes in living habits.In the sealed indoor life, the air environment directly affects the human body, resulting in the production of building syndrome, chemical hypersensitivity, and sick house syndrome. It became.
현재에는 실내환경의 쾌적성을 확보하기 위해 특히 건축자재의 오염물질 방출에 규제를 권고하고 있다. 한편, 경량 기포콘크리트 및 세라믹 보드는 친환경적인 무기질 재료로 인체에 유해한 유독가스, VOC가 방출되지 않는 천연 광물질을 주원료로한 무기질 제품이다.At present, in order to ensure the comfort of the indoor environment, it is recommended to regulate the emission of pollutants in building materials. On the other hand, lightweight foam concrete and ceramic boards are eco-friendly inorganic materials, which are inorganic products made of natural minerals that do not emit toxic gases and VOCs harmful to the human body.
상기 기술한 경량 기포콘크리트는 내구성이 확보되고 콘크리트의 미분쇄 및 슬러리화의 공정을 통하여 자체에 함유하고 있는 실리카, 산화알루미늄, 산화칼슘의 주성분으로 내구성 및 재활용성능이 확보되어 공동주택 건설폐기물로 발생되는 처리 비용을 절감하고 지구환경 보호에 기여하고 있다. The above-mentioned lightweight foam concrete is secured in durability, and the durability and recycling performance is ensured as main components of silica, aluminum oxide, and calcium oxide contained in itself through the process of pulverizing and slurrying concrete, resulting in waste of construction of apartment houses. It reduces the processing costs and contributes to the protection of the global environment.
그리고 방음에 대한 필요성은 도로변, 철도변, 공항주변, 작업장, 건설현장, 중장비, 아파트나 사무실과 같은 공동주거시설, 음악당이나 극장과 같은 공연장, 실내스포츠 시설 및 각종 위락시설과 같은 거의 모든 주변 생활환경에 요구되고 있다.And the need for sound insulation is almost all around life, such as roadsides, railroads, airports, workshops, construction sites, heavy equipment, communal housing facilities such as apartments or offices, concert halls or theaters, indoor sports facilities and various entertainment facilities. It is required by the environment.
방음방법으로는 흡음 또는 차음 성능이 있는 소재로 만들어진 각종 방음재를 사용하여, 방음벽, 방음칸막이, 방음실, 음향처리용 마감재 등과 같은 방음 구조물을 설치함으로써 소음을 흡수하고 그 전파 경로를 차단하는 방법이 널리 사용되고 있다.As the soundproofing method, various soundproofing materials made of materials with sound absorption or soundproofing performance are used, and soundproofing structures such as soundproof walls, soundproof partitions, soundproof rooms, and finishes for sound processing are absorbed and block the propagation path. It is widely used.
일반적으로 널리 사용되는 방음소재로서는, 목재 또는 콘크리트와 같은 일반적인 건축 소재, 폴리우레탄, 폴리에틸렌, 또는 폴리에스테르와 같은 합성수지재, glass wool 또는 암면과 같은 무기질섬유재, 및 금속타공판과 같은 금속재 등 여러 가지 단독 또는 복합한 것들을 들 수 있다.In general, the soundproofing materials widely used include various materials such as general building materials such as wood or concrete, synthetic resin materials such as polyurethane, polyethylene, or polyester, inorganic fiber materials such as glass wool or rock wool, and metal materials such as metal perforated plates. Single or combination thereof.
방음재는 그 사용 장소와 용도에 따라 다소 차이는 있겠지만, 광범위한 주파수 영역에서의 우수한 흡차음성, 우수한 기계적 특성(내구성 등) 및 열적 특성(불연성, 난연성 등)을 구비하면서도, 제조원가가 저렴하고 시공이 간판한 것이 바람직할 것이다. 그러나 종래의 방음재들은 상기한 여러 가지 요건들 중 일부의 요건에 부합하지 못하여 방음설비의 구축에 이들을 적용함에 있어서 상당한 문제점 들을 내포하고 있다. Sound insulation materials may vary depending on the place and purpose of use, but they have excellent sound absorption and sound resistance in a wide frequency range, excellent mechanical properties (durability, etc.), and thermal properties (non-flammability, flame retardancy, etc.), but are inexpensive in manufacturing cost and easy to install. One would be desirable. However, conventional soundproofing materials do not meet the requirements of some of the various requirements described above, and there are significant problems in applying them to the construction of soundproofing equipment.
목재나 플라스틱 수지로 된 방음재는 열에 약하여 화재에 취약하다는 문제점이 있고, glass wool이나 암면 등은 환경오염의 원인으로 작용하는 문제점이 있으며, 알루미늄판은 자체의 소음방지성능이 충분하지 못하다는 한계가 있다. 또한 금속재를 제외한 종래의 방음재는 거의 재활용이 불가능하여 폐기시 많은 산업폐기물 을 발생시키고 있다. Soundproofing materials made of wood or plastic resin are weak to heat, which is vulnerable to fire, and glass wool or rock wool have the problem of causing environmental pollution, and aluminum plates have a limitation that their noise protection performance is not sufficient. have. In addition, conventional soundproofing materials, except for metal materials, are almost impossible to recycle, thus generating a lot of industrial waste.
기재(Matrix)로서 glass wool, 암면, 폴리우레탄, 폴리에틸렌, 등을 사용하고 그 표면에 타공박판을 부착하여 공명 원리에 의해 방음효과를 향상시키고 있는 종래의 타공 구조형 방음 벽체도, 상기 기재인 glass wool이나 폴리우레탄 등이 지니는 본질적인 단점으로 인하여 전술한 여러 가지 문제점을 내고하고 있다.The conventional perforated structural soundproof wall which uses glass wool, rock wool, polyurethane, polyethylene, etc. as a matrix and attaches a perforated thin plate on its surface to improve the soundproofing effect by the resonance principle is also glass wool as the substrate. Due to the inherent shortcomings of polyurethane and the like, the above-mentioned problems have been raised.
일반적으로 내화 구조란 건축물이 장시간의 화재 시에도 재료의 형태나 강도 등이 크게 변하지 않고 견디어 내어 인명 및 재산을 보호하고, 화재 후 간단한 수선으로 건축물의 재사용이 가능케 하는 구조를 말하는 것으로서, 최근에는 내화구조인정 및 관리 기준이 법규화 되면서 그 기준이 보다 강화되었다.In general, a fireproof structure refers to a structure that allows a building to endure without changing the form or strength of the material even after a long fire without protecting the life and property, and to reuse the building by simple repair after a fire. Structural recognition and management standards have become more stringent as they become legal.
한편, 일반적으로 건축물을 신축할 때, 건축물의 구조를 지탱하고 내부를 구획하기 위해서 형성되는 벽체는 대부분이 벽돌을 축조하거나 또는 몰타르를 거푸집에 타설하여 양생하는 방식을 주로 적용하였으나, 최근에는 '경량벽체'라 하여 합판이나 석고보드 등을 이용하여 벽체의 내, 외부를 구성한 후 그 내부에 흡음재 등을 충진하여 벽체를 구성하는 방식의 적용이 점차 확대되고 있는 실정이다.On the other hand, when constructing a building in general, most of the walls formed to support the structure of the building and partition the interior are mainly applied to the method of cultivating bricks or placing mortar on the formwork to cure them. Walls are used in the interior and exterior of the walls using plywood or gypsum board, and the application of a method of constructing the walls by filling the sound absorbing material into the interior is gradually expanding.
그리하여 최근에는 건축물의 외벽체는 벽돌이나, 콘크리트 몰타르를 이용하 여 형성하고, 건축물의 내부에서 건물을 구획하는 내벽체는 상기한 바와 같이 합판이나 석고보드를 활용한 경량벽체를 많이 사용하고 있는 실정이다.Therefore, in recent years, the outer wall of the building is formed by using brick or concrete mortar, and the inner wall of the building that partitions the building from the inside of the building uses a lot of lightweight walls using plywood or plasterboard as described above.
그런데 종래의 경량 벽체는 조립 및 해체가 용이하고 경량이기도 하지만, 건물의 상,하부에 경량 강제로 된 웃막이(METAL RUNNER)와 밑막이(METAL RUNNER)를 설치한 후 웃막이와 밑막이 사이에 경량 강제로 된 샛기둥(METAL STUD)을 설치하 고, 이 샛기둥 사이의 내측과 외측에는 각각 방화석고보드를 설치한 후 석고보드 사이에 glass wool이나 암면과 같은 방음 단열재를 충진하여 경량 벽체를 설치하기 때문에, 시공 과정이 복잡하고, 많은 노동력을 필요로 할 뿐 만 아니라, 차음성이 크게 떨어지며, 특히 열에 견디는 내화성이 약하기 때문에, 최근 부각되고 있는 내화구조의 안전성이 크게 떨어지는 문제점이 있었다.By the way, the conventional lightweight wall is easy to assemble and dismantle and is also lightweight, but after installing METAL RUNNER and METAL RUNNER on the upper and lower parts of the building, the lightweight wall between the upper and the bottom METAL STUD is installed, and fireproof gypsum boards are installed on the inner and outer sides between the pillars, and a lightweight wall is installed between gypsum boards by filling sound insulation such as glass wool or rock wool. As the construction process is complicated and requires a lot of labor, the sound insulation is greatly inferior, and in particular, the heat resistance is weak, and the safety of the fire resistant structure, which has recently emerged, has been greatly deteriorated.
본 발명은 이상의 같은 종래 방음재들에서의 여러 문제점들을 감안하여 창출된 것으로서, 흡음재 및 차음재인 경량기포콘크리트층의 일측면에 세라믹코팅 또는 방수코팅을 한 보드를 설치함으로써 2중의 소음흡수 및 완화작용을 하는 기능이 있으며, 시공이 용이하고 내구성을 유지할 수 있으며, 벽체의 경량화로 인하여 시공이 용이하게 수행할 수 있는 경량벽체를 제공함에 목적이 있다.The present invention has been made in view of the above problems in the conventional soundproofing materials, and by installing a board coated with a ceramic coating or waterproof coating on one side of the light-weight foam concrete layer, which is a sound-absorbing material and sound-proofing material, double noise absorption and mitigation effect. There is a function to, easy to construction and can maintain durability, and the purpose of providing a lightweight wall that can be easily performed due to the weight of the wall.

즉, 벽체의 중앙은 심재로 구성되고, 심재의 일측면에는 보드가 에폭시, 멜라민, 폐놀계 접착제 중에서 어느 하나를 이용하여 부착된 것을 특징으로 하며, 상기 심재는 경량 기포 콘크리트 패널, 경량 콘크리트 패널, 셀룰로즈 섬유보강 콘크리트 패널 중에서 선택된 어느 하나로 하고, 보드는 마그네슘보드, 셀룰로즈 보강 시멘트보드, 시멘트 압출판 중에서 선택된 어느 하나인 것을 특징으로 하며, 상기 보드의 표면에 마감 처리되는 도장마감재는 세라믹코팅 또는 방수코팅인 것을 특징으로 하고, 한편으로는 경량 기포 콘크리트 패널을 심재로 하되, 표면은 퍼티로 고름질한 후 도장재로 세라믹 코팅을 하는 것을 특징으로 하게 된다.That is, the center of the wall is composed of a core material, one side of the core material is characterized in that the board is attached using any one of epoxy, melamine, phenol-based adhesive, the core material is a lightweight foam concrete panel, lightweight concrete panel, Any one selected from cellulose fiber reinforced concrete panels, characterized in that the board is any one selected from magnesium board, cellulose-reinforced cement board, cement extruded plate, the surface finish of the coating is ceramic coating or waterproof coating It is characterized in that, on the other hand, the lightweight foam concrete panel as a core material, the surface is characterized in that the ceramic coating with a coating material after the puddle.
본 발명의 세라믹이 보드의 표면에 코팅된 세라믹보드는 환경적인 신기술 건축재료로서, 내화, 방수, 고강도 및 저 열전도성, 치수 안정성, 내구성, 각종 가공성을 갖추고 있다. The ceramic board coated with the ceramic surface of the board of the present invention is an environmental new technology building material, and has fire resistance, water resistance, high strength and low thermal conductivity, dimensional stability, durability, and various processability.
특징으로는 습기에 대한 변형이 없고, 유해 전자파 및 정전기 흡수 성능이 우수하고 높은 강도를 가지고 있으며, 충격에도 잘 견디어 쉽게 부러지지 않는다. It is characterized by no deformation against moisture, excellent absorption of harmful electromagnetic waves and static electricity, high strength, good resistance to shock, and not easily broken.
또한, 친환경적인 건축자재로서 인체에 유해한 유독 물질이 포함되지 않았으며, 표면에 페인트나 벽지 각종칼라 코팅, HPM(High Pressure Melamine)접착등 2차 가공이 가능하다. 세라믹보드로서는 마그네슘보드, 셀룰로즈 보강 시멘트보드, 시멘트압출판등으로 구성되어 있다. In addition, as an environmentally friendly building material, it does not contain toxic substances harmful to the human body. Secondary processing such as paint, wallpaper, various color coatings, and HPM (High Pressure Melamine) adhesion are possible. The ceramic board is composed of magnesium board, cellulose-reinforced cement board, cement extrusion plate and the like.
상기 세라믹보드는 경량기포콘크리트의 내측 또는 외측에 설치되며, 소음원으로부터 발생된 소음을 1차적으로 흡수 및 완화시키는 역할을 한다. The ceramic board is installed inside or outside the lightweight foam concrete, and serves to primarily absorb and mitigate the noise generated from the noise source.
이와 같은 세라믹보드는 주성분이 무기자재인 포틀랜드 시멘트, 규사, Cellulose fiber, 혼화제등으로 구성되어 있으며, 소음 및 방음시설을 위한 자재나 친환경건축자재 등으로 사용되고 있는 제품이다. Such ceramic board is composed of portland cement, silica sand, cellulose fiber, admixture, etc., which are main components, and is used as a material for noise and soundproofing facilities or environmentally friendly building materials.
즉, 세라믹보드는 독립구조의 집합이지만 이격막에 압축가공 등의 수단에 의해 물/시멘트 비율이 적기 때문에 면밀도가 높아 소음을 차단하는 차음성능 및 치밀한 강도를 유지하는 성능이 뛰어나 쾌적한 실내환경을 조성한다.In other words, the ceramic board is a set of independent structures, but because of the small ratio of water / cement by means of compression processing, etc., the surface area is high, so the sound insulation performance that blocks noise and maintains dense strength create a pleasant indoor environment. do.

그리고 상기 경량기포콘크리트는 시멘트, 생석회를 주 원료로 한 석회질 원료와 규산질 원료를 이용한 수화반응으로 상온상압에서 타설적층 후 체적량의 150∼200%를 후발포시키는 제법으로 제공되는 무기물질 경량기포콘크리트(ALC)이다.In addition, the lightweight foam concrete is an inorganic material lightweight foam concrete provided by a method of post-foaming 150 to 200% of the volume after pouring at normal temperature and pressure by a hydration reaction using a lime material and a siliceous material mainly composed of cement and quicklime. (ALC).
경량기포콘크리트(ALC)는 고온·고압하에서 양생 과정을 거쳐 구조적으로 안정한 판상 미세 결정 구조의 tobermorite상 결정을 이루는 과정에서 만들어지는 다공질 경량 콘크리트로서, Autoclave는 제조과정에서 사용되는 고온·고압증기 양생기를 의미한다. ALC의 국제적인 학술용어는 AAC(Autoclaved Aerated Concrete)라고 하는데 이는 혼합제와 같은 화학물질로 콘크리트 내 기공을 생성하여 자연 양생한 다공질 경량 콘크리트와는 구별된다.Lightweight aerated concrete (ALC) is a porous lightweight concrete made during the process of curing under high temperature and high pressure to form a tobermorite phase crystal with a structurally stable plate-like microcrystalline structure. it means. ALC's international terminology is called AAC (Autoclaved Aerated Concrete), which is distinguished from naturally cured porous lightweight concrete by creating pores in concrete with chemicals such as mixtures.
ALC의 기포는 그 크기에 따라 Macro pore(거대기공)와 Micro pore(미세기공)로 구분되는데 이들 기포는 전체 ALC의 체적에 70~80%를 차지하여 물질은 단지 20~30%밖에 되지 않기 때문에 이들 대부분의 기포들로 인해 ALC는 물에 뜰 정도의 아주 낮은 비중(0.5~0.7)의 특성을 지니게 된다. 또한 ALC가 지닌 대부분의 특성 즉 단열성, 내화성, 차음성, 내구성, 등이 이들 기포로 인하여 발현되는 것이다.Bubbles of ALC are classified into macro pores and micro pores according to their size. These bubbles occupy 70 to 80% of the volume of the entire ALC. Due to most of these bubbles, ALC has a very low specific gravity (0.5 to 0.7) that floats on water. In addition, most of the characteristics of ALC, such as heat insulation, fire resistance, sound insulation, durability, etc. are expressed by these bubbles.
* 물리적 특성* Physical properties
가. 경량성 end. Lightweight
ALC는 중량이 보통 콘크리트의 약1/4(비중:0.6)이므로 물에 뜰 정도로 가볍기 때문에 건물의 경량화가 이루어져 구조체 절감으로 인한 경제적인 건축이 가능할 뿐만 아니라 운반 및 작업효율이 한층 높다.ALC is usually about 1/4 of concrete (specific gravity: 0.6), so it is light enough to float on water, making the building lighter and economically constructive due to structural reduction, as well as higher transportation and work efficiency.
나. 단열성 I. Heat insulation
미세한 기포로 인해 보통콘크리트(열전도율:0.8㎉/mh℃)의 10배 단열 성능을 가지고 있어 별도의 단열재를 쓸 필요가 없다. 또한 냉난방에 대한 에너지비용을 절감할 수 있다.Due to the fine bubbles, it has 10 times the insulation performance of ordinary concrete (heat conductivity: 0.8㎉ / mh ℃), so there is no need to use a separate insulation material. In addition, energy costs for heating and cooling can be reduced.
다. 내화성 All. Fireproof
2시간 내화시험을 통하여 시험체의 허용온도범위내에 존재하였으며, 가열시작에서 종료시점까지 무기질소재를 원료로 사용하는 불연재로서 연기나 유독성 가스를 전혀 발생시키지 않으며, 내화성능기준에 적합하다.It was within the allowable temperature range of the test specimen through a 2-hour fire resistance test. It is a non-combustible material that uses inorganic material as a raw material from the start of heating to the end of the heating.
라. 차음성 la. Sound insulation
무수한 독립기포로 구성되어 있어 차음성이 뛰어나기 때문에 소음이 심한 곳에 차음구조로 사용할 수 있다.It is composed of a myriad of independent bubbles, so the sound insulation is excellent.
마. 내구성 hemp. durability
양생 시 조직이 안정된 새로운 광물질을 생성해 내기 때문에 수축 및 팽창력이 적고 동결융해 내구성이 탁월하다. 또한 곰팡이, 습기, 결로 등의 문제가 발생하지 않는다.When cured, the tissue produces stable new minerals, so it has less shrinkage and expansion, and excellent freeze-thawing durability. In addition, no problems such as mold, moisture, condensation.
