Description

  The present invention relates to a non-combustible door composed of a thin steel plate, a skeleton of bone and internal rock wool, and is excellent in sound insulation and fireproof insulation using an inner and outer steel surface plate and a shielding agent. It relates to doors with light weight, sound insulation and fire resistance.

  Conventionally, various structures have been proposed for sound insulating and non-combustible building materials. Among them, magnesium hydroxide has been used as a non-combustible building material because of its excellent non-combustibility, but since the main material component is granular or powdery, it has brittleness to impact, so it uses a fibrous reinforcement. It was common to do.

A ceramic board and a flame-retardant veneer in which a glass fiber base fabric surface layer is formed on one surface or both surfaces of a core layer including a magnesium-based inorganic material and a lightweight chip are disclosed. However, even if the weight of the ceramic board itself can be reduced, there have been proposed insufficiencies such as heat insulation, heat retention, and sound insulation (see Patent Document 1).

In order to improve sound insulation, a flame-retardant synthetic building material is disclosed in which magnesium hydroxide is mixed with an inorganic fiber material such as glass fiber or organic fiber such as natural cellulose fiber or nylon fiber and pressed. In this synthetic building material, these fibrous substances are mixed to provide reinforcement, light weight, and nail retention. However, although this building material has a certain degree of impact resistance, it still has brittleness and lacks toughness (see Patent Document 2).

A substrate is formed on the core material through a bonding material, a moisture-proof layer mixed with an adsorbent is formed on the substrate, a decorative board is formed on the moisture-proof layer, and the core material and the substrate There has been proposed a flash door having a hollow portion formed in an enclosed portion (see Patent Documents 3 and 4).

A pair of front and back first substrates are formed on the front and back surfaces of the core material via a bonding material, and an intermediate core material having a through hole is formed on the surface of the first substrate via the bonding material, and on the back surface of the backing material A pair of front and back second substrates via a bonding material, and a pair of front and back decorative plates via a bonding material formed on the surface of the second substrate, and an intermediate hollow portion surrounded by the core material and the first substrate Is provided with a sound insulation heat insulating door filled with an inorganic lightweight foam or inorganic fiber (see Patent Document 5).

In a fireproof / fireproof panel comprising a combination of a heat-expandable refractory material and a wood board, the heat-expandable refractory material contains 70 inorganic fillers per 100 parts by weight of epoxy resin and / or rubber-like substance and / or thermoplastic resin. ˜500 parts by weight, of the inorganic filler, containing at least 10 to 150 parts by weight of a layered inorganic material that expands upon heating, and having a thickness of 0.1 to 4 mm, the wood board has a density of 0.4 g / cm ^3. With the above brazing material and a core material having a density of 0.6 g / cm ³ or less, the density of the brazing material is relatively larger than the density of the core material. Proposed anti-fire / fire-proof panel that is assembled in any of the shape of a letter, a rice field, a ladder, or a lattice, and the expansive refractory material is laminated on at least one side and / or inside of the wooden board. (See Patent Document 6).

In facilities such as hotels and lodging facilities, doors that are not only incombustible, flame-retardant, heat-insulating, and heat-insulating, but also sound-insulating, and lightweight and robust are expected. Almost does not exist. There is also no light, sound-insulating, and fire-resistant door that can be used as a door for public facilities or facilities where many people gather.
