Description
Technical field
The present invention relates to a kind of aerial steel vestibule Lift-on/Lift-off System of multilayer and its application methods.
Background technology
Executive information systems are quickly grown at home at present, and function is increasingly sophisticated with shape, aerial conjoined structure
Using also more and more extensive.Such conjoined structure is mostly steel construction, usually with structure height is high, span is big, installation difficulty is big
The features such as.
The features such as conjoined structure generally has span big, and mounting height is high, assembling and welding job amount are big, traditional steel vestibule
Installation method includes erection by protrusion, high-altitude moulding bed assembly method, Integral Lifting etc..Traditional steel vestibule installation method is primarily present
Following deficiency：
1) Deformation control difficulty is larger in erection by protrusion work progress, and assembled time-consuming, installation effectiveness is low, required precision
Height, and the security risk of working at height is big；High-altitude moulding bed assembly method requires height, working measure to take height, economy assembled moulding bed
Difference, and it is high to lower part assembly moulding bed and support construction force request.
2) in contrast, Integral Lifting has construction efficiency high, reduces high-altitude and dissipates spelling security risk, but to being promoted
Machinery, assembled place are more demanding.For composite steel vestibule, (assembled place is small, place bearing capacity under certain site conditions
It is low), limit the implementation of Integral Lifting.
3) due to initial installation deviation or hoisting frame stress etc., cable wire is easy to tilt and even knot between upper and lower suspension centre, no
In same perpendicular, cable wire oblique loading is caused.
