Description
Technical field
The utility model relates to the realm of building construction, particularly relates to a kind of slippage moulding bed that is used for the large-span steel construction.
Background technology
Along with the rapid development of national economy, large-span space structure is flourish, and the moulding of existing design is more and more novel, unique, and structure becomes increasingly complex, and span is also increasing.Modern's rhythm of life speeds simultaneously, and market condition is fast changing, causes the owner also more and more higher to the requirement of duration.Traditional construction technology can't satisfy the needs of construction, each unit in charge of construction takes the reform of constructing of various means: increase large-scale plant, change the system of management, increase labour and labour hour, but all these schemes can't make all execution conditions fundamentally be changed.So it is inevitable that the change on the construction technology becomes, slippage, the whole tipping that promotes, builds bridge etc. was used for the Construction of Steel Structure that technology that the bridge structure build begins to be applied to longspan structure in the past.
High-altitude sliding method i.e. net shell bar element always is being combined into whole method after in place by an end slippage on the building to design attitude.According to the difference of slipping, mode etc., sliding method can be classified by following five kinds of forms, and the first, be divided into wall scroll sliding method and accumulation slippage method one by one by the mode of sliding: the second, can be divided into tumbling-type and slidingtype slippage by friction mode in the slipping; The 3rd, can be divided into moulding bed slippage, main structure body (net shell) slippage, net shell integral slipping method by slippage object in the slipping; The 4th, can be divided into straight line slippage and curve sliding by the sliding rail arrangement; The 5th, be divided into slippage of traction method and incremental launching method slippage by the slippage tractive force mode of action.
But the high-altitude sliding method generally is used in the less Construction of Steel Structure of span more, and in large-span steel (general span reaches more than the 40 meters) construction, because span is big, skidding distance is far away, the used slippage moulding bed of existing sliding method all can't use, therefore, adopt high altitude bulk method or itemize or piecemeal installation method to install more.The high altitude bulk method is the method that smallest assembled rigid unit or loose mail (single rod member and individual node) are directly always pieced together at design attitude (high-altitude).This method usually needs set up full framing at the installed position of member, and at the full framing top or proper site lay plank, form the high-altitude operation platform.And itemize or piecemeal installation method are that rack is divided into strips or block unit, are lifted in place the shelving in high-altitude design attitude place by crane respectively, and then are assembled into whole installation.The high altitude bulk method exists the bracing frame consumption big, and the installation of bracing frame and dismounting work are heavy, can cause the duration of structural steelwork self longer, can not satisfy the shortcoming of ubiquitous strong workload, the requirement of casual labourer's phase in the engineering; And a large amount of inputs of zero time property facility (especially bracing frame) cause construction cost to increase, and can not realize economy; Setting up of full framing need take land used in the building field in a large number, and the increase of the overall land used amount that can cause constructing makes that simultaneously the cross-operation with specialty such as civil engineering is difficult to realization, more increases the risk of honouring an agreement of overall duration.
Itemize or piecemeal installation method are that rack is divided into strips or block unit, are lifted in place the shelving in high-altitude design attitude place by crane respectively, and then are assembled into whole mounting method.When itemize or piecemeal installation method exist the high-altitude to install, need bracing frame to be set at the node place of piecemeal, itemize etc., for large-area venue class space truss structure, the consumption of bracing frame is also bigger, and cost is bigger, sub-economic shortcoming, and since lack complete, large tracts of land aerial work platform (general only the bracing frame top among a small circle in the laying platform), cause the work high above the ground difficulty bigger, dangerous big, the safety guarantee difficulty.
