Technical field
The present invention relates to how high-rise assembling type steel structure interlock girder steel prestressing force center support system,Belong to technical field of structural engineering.
Background technology
Traditional housing building of steel-structure is not brought into play the superiority of steel house completely, along withThe development of China's steel building technology, many high-rise steel structure system should adopt design moduleChange, component standardization, promote industrialization with standardization, promotes the basic of industrialization with industrializationDevelopment principle, but in assembling type steel structure system, the on-site consolidation node of Liang Heliang is oneIndividual key issue. In existing assembling type steel structure system, what conventionally adopt is two channel-section steelsCarry out assembledly, the docking of the web of two channel-section steels, connects by bolt, forms assembled HShaped steel. But in this connecting method, shearing is to pass to web by bolt, webFor plain plate, so the steel using amount of required Number of Bolts and web is very large, shear-carrying capacity needsImprove. Meanwhile, while being applied in the assembling type steel structure system of large span, traditional assembledSteel member will increase height and the area of beam section significantly, has increased steel using amount.
As can be seen here, traditional Steel section member is used in to assembling type steel structure system among effect notBe very desirable, not only affect the stress performance of member, and need to consume a large amount of steel, produceRaw unnecessary waste. In sum, create the assembling being formed by a kind of novel primary structure memberFormula steel structure system is the only way which must be passed of assembling type steel structure development.
