Description

Net structure lightweight concrete assembled large panel
Technical field
The present invention relates to assembled architecture technical fields, more particularly, to a kind of net structure lightweight concrete assembled large panel.
Background technology
Recommendation housing industrialization is set to fundamental state policy by China, and government is just promoting the development of assembled-type house with all strength.Dress Nuclear structure component with formula house is exactly assembled large panel.This big plate is different from traditional architecture partition wall batten:One is width Face is big, and big plate, floor and the roof boarding of a general standard width of a room in an old-style house are respectively one piece of whole plate, and size is at 10 square metres to 20 squares Between rice;It the second is intensity is high, can be installed with integral lifting, and there is excellent anti-shear performance;The third is Side fascia, partition wall Plate, floor and four plate of roof boarding are mating, can be assembled into complete house main body.And China's production application in the past is mostly Small dimension batten, area only between 1.5 square metres to 1.8 square metres, are mainly used for partition plate, may not apply to Side fascia, Floor and roof boarding, can not be mating between major plate.Although the foam cement composite plate breadth occurred later is larger, also not More than 10 square metres, and mostly it is that batten is not used to assembled-type house, is confined to industrial premises and large public building.This The market vacancy for resulting in the big plate of China native country assembled-type house makes the assembled-type house that the Chinese government promotes occur " under no rice The predicament of pot ".
At home without house assembled large panel in the case of, for that should be badly in need of, China has to the hairs such as comprehensive equipment Imported From German EMH Company Up to the loaded concrete assembled large panel production line technology of country.This big plate is referred to as " PC concrete large slab " in the market." PC " is The abbreviation of English precast concrete (assembled).At present China have PC concrete large slab production line hundreds of, substantially Spread all over the country each province urban district.Currently, it is built and in the PC houses built, entirely use this big plate of PC loaded concrete.But it is this Although the big plate of PC loaded concrete is since policy encourages the dynamics promoted very big, application amount is very pessimistic, most of production lines Halfload production even end-of-life state, product do not have market, the foreign technology awkward situation not acclimatized in China occur.Study carefully its original Cause is substantially policy project and such as moves back room, low-rent housing, economic and practical using the residential project of this PC concrete large slabs The demonstration room etc. that room, government fund are helped, large-scale commercial residential buildings are not applied substantially.
Applicants have discovered that at least there is following technical problem in the prior art:
Existing big every cubic metre of the plate of the loaded concrete for occupying policy house market expends steel, cement, sand, stone total weight It it is 2.7 tons or more, every square metre of housing design is 2200 to 2700 yuan, and capital consumption is higher than traditional residential 20% to 30%;And Due to leading to poor seismic behavior from great, and then foundation engineering is increased, so that its application region is restricted, in addition loaded concrete Big plate heat transfer is big, does not keep the temperature, and the duration can be extended by needing to do secondary heat preservation.Therefore the big plate of loaded concrete of this imported technology belongs to In low cost performance product.
Invention content
