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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
