Description
Technical Field
The application relates to the technical field of construction and installation of building steel structures, in particular to a construction method for layered lifting of a large-span hollow corridor steel platform.
Background
With the increasing shortage of urban building land, the pursuit of people for building art is continuously improved, and the construction cost is increased dramatically day by day. In the definition of modern architecture, a corridor is one of complex high-rise building structural systems, and generally means that two or more high-rise buildings are connected with each other by an overhead connector so as to meet the requirements of building shape and service function. The connecting body is a corridor. The span is several meters long and also several tens of meters long. The vestibules are arranged one by one or a plurality of in the vertical direction of the building.
For the rapid and efficient construction of multi-layer vestibules among buildings, the traditional method is to install a vestibule steel platform which is equivalent to the foundation part of the vestibule and then carry out the integral construction of the vestibule on the steel platform. Because vestibule steel platform is mostly fretwork form girder steel structure, also is called empty stomach vestibule steel platform. When a multi-layer large-span corridor is constructed between high-rise buildings, cost, safety and construction simplicity must be considered for a proper lifting method of a hollow corridor steel platform.
When the vestibule height is not very high, generally set up the support pylon, adopt the mode of large-scale crane hoist and mount, from up successive layer installation completion down, if the vestibule height is too high, the plane dimension is too big, and when the construction site does not possess large-scale loop wheel station yet, just need consider assembling at ground or floor normal position, the mode of successive layer whole hydraulic lifting realizes, promote hoisting point fixes on the building subject at top layer vestibule place during successive layer promotes, because install the pre-assembly at the installation layer in advance, just so can only from up successive layer lifting steel platform down, but lower floor steel platform installation back, upper steel platform need bypass lower floor steel platform from the side and promote the installation again, lead to the hoist and mount place big, hoist and mount inefficiency. Although the multi-layer platforms can be assembled and stacked on the ground in situ, the operation is difficult in practice.
In the prior art, the patent number CN201710326724.9 provides a lifting construction method for a plurality of steel galleries between tower buildings; the essence of the method is that on the basis that the lower steel platform is installed, the upper steel platform is assembled on the lower steel platform and then integrally lifted. Because the hollow corridor steel platform is only a basic frame of the corridor, the hollow corridor steel platform has no actual construction working surface, and the safety performance of the hollow corridor steel platform serving as an assembling working surface is poor. Meanwhile, the problem of the standing position of the auxiliary crane is also considered during the actual assembly operation.
