[0021] The construction method for hoisting the platform steel column provided by the present invention will be described in detail below with reference to the drawings and specific embodiments.
[0022] Now take a railway station reconstruction project as an example to illustrate: the railway station is located in the center of the urban area. The new steel canopy covers an area of 43754.3m2 and a total width of 114.6m. The east-west direction PA, PB, PC, PD has four axes, 18 axes in north-south direction, with a total length of 381.8m. The elevations of the arches of the rain canopy are 14m and 16.8m respectively, and the corresponding steel column top elevations are 17m and 19.8m (P7~P9 axis and P10~P12 axis) respectively.
[0023] Such as Figure 1 to Figure 3 As shown, the construction method for hoisting a platform steel column provided by the present invention includes the following steps in sequence:
[0024] 1) Before the steel column 1 is hoisted, the construction perso...
