Abstract
The utility model discloses a large span steel structure high-altitude subsection hoisting support system which comprises a temporary support frame comprising a subgrade, a main support structure connected to the subgrade, an upper part steel frame connected to the main support structure and a wind embracing rope. The main support frame is a plurality of sections of tower hoisting standard knots which are mutually connected, the wind embracing rope is arranged between the upper part of the main support structure and the ground in a connecting mode, and a lifting jack is arranged on the top of the upper part steel frame. According to the large span steel structure high-altitude subsection hoisting support system, the main support structure is formed by the tower hoisting standard knots, and thus the construction is convenient, the installation time is short and the disassembly is convenient, the construction safety is ensured and the economic benefit is remarkable. The temporary support frame is provided with the subgrade and the wind embracing rope, so that the temporary support frame is more safe and reliable.
Description
Technical field
The utility model relates to a kind of lifting support system, particularly relates to the high-altitude segmented lifting support system of a kind of large-span steel.
Background technology
For large-span steel, be divided into job practicess such as high-altitude segmented lifting, integral slipping, installation on ground integral hoisting basically.Take all factors into consideration factors such as construction cost, security risk coefficient and construction environment, at present, adopting maximum is high-altitude segmented assembly unit, and this method requires in upper air installing, member to be supported, and carries out smoothly to guarantee the safety of docking.Adopting at present maximum is that the load-bearing scaffold supports with lattice column and supports, but these two kinds of methods all have its limitation, has all that construction cost is relatively large, length, safety factor do not have relevant drawbacks such as reliable guarantee, complicated operation to construction period.
