Description
Technical field
The utility model relates to light gauge cold-formed steel shape building construction technology field, specially a kind of light gauge cold-formed steel shape is compound
Gypsum lightweight outer wall body.
Background technique
One, the wall structure Shortcomings of modern low layer light gauge cold-formed steel shape building
The wall of modern low layer light gauge cold-formed steel shape building is by light gauge cold-formed steel shape skeleton, wall body structure panel
(cement plate, plasterboard, calcium silicate board with microporous and OSB plate etc.), lumen loading fireproof heat insulating cotton or hard polyurethane foam etc. pass through screw
Connect the complex being composed.
This wall compared to traditional architecture blockwork construction, transport, antidetonation, in terms of have it is very big excellent
Gesture, but also have many deficiencies, it shows themselves in that
It 1, is substantially hollow structure among light gauge cold-formed steel shape retaining wall, it is easy to form " eardrum " effect, hit
Soundproof effect is very poor, and " cavity wall " structural form of formed steel construction retaining wall two sides covering plate allows and gets used to " Qin Zhuanhan
Watt " Chinese of solid wall are beyond affordability.
2, exterior wall plate stitch leads to external wall seepage, paint film bubbling and other issues, influences to decorate because of the easy cracking of difference variation
And using effect.
3, fireproof heat insulating cotton quality is different, and second-rate fireproof heat insulating cotton will disperse out to swim in air for a long time
Tiny, naked eyes almost invisible fiber, after being sucked by human body, gradually deposits and gives rise to diseases in lung；And hard is sent out
It is poor to steep polyurethane fireproof performance, it is sustainable to volatilize the substance that is harmful to the human body.
Two, industry by-product gypsum especially ardealite utilization rate is low
The year yield of China's industry by-product gypsum is about 1.84 hundred million tons, wherein newly-increased 70,000,000 tons of ardealite every year；Phosphorus
It is more than 300,000,000 that gypsum, which adds up volume of cargo in storage, and for utilization rate less than 20%, the overwhelming majority is taken as waste to abandon.
Phosphogypsum slag stockpiling occupies a large amount of soils；Its acidity contained and other harmful substances are easy to make surrounding enviroment
At pollution, runed counter to the fundamental state policy of China's protection environment！If not increasing using disposition, by the hair of extreme influence phosphate fertilizer industry
Exhibition.
Currently, the industry by-product gypsums such as ardealite, are mainly used in cement retarder, Thistle board and gypsum hollow and build
Block, consumption tend to be saturated, it is therefore necessary to extend other application direction.
