Description

Steel wire net rack expanded perlite combined wall board

The utility model relates to New Building Materials, is specifically related to a kind of composite fireproof warming plate that is used for replacing building clay tile wall, roof panel, i.e. steel wire net rack expanded perlite combined wall board.

In building operations, limit solid clay brick, be intended to adjust structure, energy-conservation, the water saving that saves land, reduce environment pollution, in recent years, various places building material, novel wall material are like rain the back spring bamboo, once Re Men steel wire net rack polystyrene combined wall board (Taibai panel) had also once played the promotion wall reform, accelerate the leading effect of building field reform, along with the proposition of Ministry of Public Security nineteen ninety-five about steel wire net rack polystyrene core bar " fire prevention " problem, some building storeys are subjected to using restriction in succession, and nearly more than the 200 tame factories in the whole nation face the row of stopping doing business and wander.

The purpose of this utility model provides a kind of building material, specifically, the purpose of this utility model provides and a kind ofly can overcome the set fire light-weight walling material of poor performance shortcoming of prior art combined wall board, this materials for wall is not only in light weight, and having fabulous fire prevention, insulation, sound insulation, antibiotic, antidetonation, corrosion resistance, cost of production is also low.

The purpose of this utility model is to realize like this, construct a kind of steel wire net rack expanded perlite combined wall board, it is characterized in that welding three-dimensional steel wire net rack with machinery is skeleton, mutually compound with the expanded perlite of wrapping up in inorganic glue gluings such as water glass in the fiberglass gridding cloth, core bar that vermiculite is made, after cement mortar is smeared in the spray of central layer two sides at the construction field (site), form the novel building wallboard of the antibiotic function admirable such as nonpoisonous and tasteless of fire prevention, high-strength anti-shock, light sound-proof.

The steel wire net rack expanded perlite combined wall board that provides according to the utility model, it is characterized in that in the three-dimensional steel wire net rack of described machinery welding, the rack steel wire diameter is 2.0～3.5mm, the steel wire spacing of net sheet is 30～100mm, net sheet thickness is between 40～300mm, connects between the steel wire or vertical or undulate intersects.

The steel wire net rack expanded perlite combined wall board that provides according to the utility model, it is characterized in that, with wrap up in the glass cloth core bar (or whole plate) with glass cloth with expanded pearlite core bar do two sided glued strengthen anti-, the core bar is to be that light aggregate cooperates an amount of inorganic adhesive with perlite, vermiculite, waterproof agent, the fire prevention strip core bar (or whole plate) that water etc. form through stirring, moulding, dry maintenance.

According to the steel wire net rack expanded perlite combined wall board that the utility model provides, it is characterized in that described strip core bar is meant in advance in factory to make the strip of cross section for (40～50) * (40～50) * 2400～3500mm.

The steel wire net rack expanded perlite combined wall board that provides according to the utility model, it is characterized in that the job site is installed in steel wire net rack expanded perlite or vermiculite compound core plate the region of interest of building, the cement mortar that 25mm is smeared in the spray of central layer two sides, promptly form novel fire proof construction wallboard, fire prevention reaches the A level, the intensity height, the strong and heat preservation and soundproof of shock resistance.

Implement the steel wire net rack expanded perlite combined wall board that the utility model provides, have following characteristics: 1. intensity height, three dimensions steel wire net rack with special mechanical spot welding moulding, having " body strong as iron " worthy of the name is easy to connect with frame structure system, the whole shock resistance of building building is significantly improved, be particularly suitable for high level or super highrise building.2. wall is thin: the spray of wallboard core two sides is smeared after the 25mm cement mortar becomes body of wall, and thickness is 100～110mm, effectively increases the room usable floor area.3. fire prevention is not fired: with the inorganic adhesive of specialized configuration bonding expanded perlite or vermiculite, its refractory temperature is up to 1280～1360 ℃, and the safe handling temperature is 650～800 ℃.4. insulation with the expanded perlite that directed glass grid cloth is wrapped up in mutually, has antidetonation, anti-folding, anti-crushing, characteristics such as volume stability is good, and high-efficiency insulated, and sound-absorbing has light weight simultaneously, antibiotic corrosion-resistant acidproof protection steel mesh etc.5. adopt steel wire net rack pearl stone composite wall plate, fully can the instead of clay brick, ban steel wire net rack polystyrene combined wall board, not only energy-conservation but also joint soil met the fundamental state policy that country's restriction is cut the earth and baked bricks, and also met the fire protection criteria that Ministry of Public Security's song is sent out.

In conjunction with the accompanying drawings and embodiments, further specify characteristics of the present utility model, in the accompanying drawing:
