Description
Technical field
the utility model relates to civil engineering work structure field, is specially a kind of assembling stiffness combo box support structure.
Background technology
Expect the year two thousand twenty, the level of urbanization of China will reach 57% left and right, cities and towns total population 8.28 hundred million, and in the face of the urbanization level of fast development, the demand that Urban House and industrial premises are built is increasing.
In construction market great development, due to design, the construction technology restriction of existing house and industrial premises, can not meet the requirement of the people to housing stock and quality.
(1) traditional architecture speed of application is slow, unbecoming with the urbanization level.
The construction of tradition residential standard layer also needs 5 days/layer, sky faster, adds later stage decorations, and a community residential building is delivered for use from starting building to, generally needs the time of one or two years.Presell phenomenon in house has reflected the contradiction between demand and supply in the ubiquitous situation of China, and for the industrial premises of the market for business management and production use, the time is exactly business opportunity especially.
(2) traditional architecture architecture quality is wayward.
Construction quality is the major issue that concerns the people's livelihood, can not be ignored.But the construction of traditional architecture, is subject to the impact of site operation personnel level and construction environment, and construction quality is wayward, has the reason of many common quality defects.
(3) traditional architecture cost of production is high
Because traditional architecture construction has " unique " property, owing to can not forming large-scale production, cause the waste of material, instrument etc.Labor cost improves constantly at present in addition, produces as labor-intensive traditional architecture, has also increased cost of production.
(4) traditional housing construction energy consumption is high.
At present building operations or highly energy-consuming industry, the requirement of " energy-saving and environmental protection, the sustainable development " advocated with country does not also conform to, and the construction theory of " green construction, green building " is placed to critical positions.
(5) there is more potential safety hazard in traditional architecture construction.
There are the hazards such as work high above the ground due to building operations, cause the safety problems such as building site falling from high altitude, fire to happen occasionally.
China starts to apply assembled architecture the sixties in last century, within the beginning of the seventies to the more than ten years of the mid-80, a flourishing as never before great development period has been experienced in the production of precast concrete, to the end of the eighties, prefabricated units enterprise of China has tens thousand of families, produces precast concrete quantity per year and reaches 2500 ten thousand stere left and right.But, at that time because the key technologies such as the sound insulation of assembled-type house, waterproof, anti-seismic performance are not well solved, particularly Seismic Behavior does not solve, make after Tangshan Earthquake, assembled architecture damage is serious, people have produced suspection to this form of structure, have hindered greatly the development of assembled architecture.
The combination assembled building structure of existing steel reinforced concrete exists following not enough: (1) extensively adopts steel work or steel-concrete combined structure in multilayer, high level and super highrise building, wherein frame column usually adopts steel column or steel core concrete column or profile steel concrete column, and frame support beam adopts steel-concrete composite beam or reinforced concrete beam.Adopt steel-concrete beam to there is the features such as easy construction, speed of application is fast, bearing capacity is high, span ability is strong, but also exist steel using amount large, need to adopt suitable fire prevention measure, the high deficiency of structural cost; Adopt steel concrete to there is the advantages such as fire resistance is good, structural cost is low, but larger, the span ability of its deadweight, executing the operations such as man-hour requirement formwork, cast in situs, concrete curing, form removal, construction speed is slow, and is subject to construction plant restriction ratio larger.
Existing industrialized building advantage is to complete textural association with the member of less specification, and standardization level is high, but has ignored building shape-designing, does not meet the requirement of people to construction aesthetic perception.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of simple in structure, easy construction, and span ability is large, the assembling stiffness combo box support structure that construction cost is low.
