The integrated lifting steel platform integrates multiple functions and facilities such as material stacking, rebar binding, formwork installation, concrete pouring, hanging frame, concrete placing boom, machine room warehouse, personnel rest room and simple toilet. It provides a mobile working platform for the entire construction process of the core tube of super high-rise buildings, and has the advantages of fast construction speed, good enclosure and good overall protection.

[0029] To achieve the above objectives, the present invention provides an installation method for a truss system of an integrated steel platform for super high-rise construction, used in any of the above-mentioned applications, the installation method comprising:

[0030] S1: Divide the truss system into several assembly units, arrange the lifting points for the assembly units, and determine the number of lifting points based on the weight of the assembly unit and the load-bearing capacity of the lifting lugs. The lifting points are set at the T-shaped nodes where the truss system meets the maximum lifting weight requirement of the lifting equipment.

[0031] S2: A steel pipe support frame is erected at the location where the truss cantilever is large, so that the cantilever assembly unit at the corner of the truss system becomes a simply supported structure during installation, and the main beam rests on the top support of the steel pipe support frame.

[0032] S3: The main truss assembly unit connected to the support column is hoisted using lifting equipment.

[0039] Compared with existing technologies, the truss system for an integrated steel platform for super high-rise construction provided by this invention has the following advantages:

[0040] (1) The load transmission of the truss structure is clear and reliable. The loads borne by the secondary truss, open web truss and external Bailey truss are transferred to the main truss, and the main truss transfers the load of the steel platform to the support system.

[0041] (2) The hollow truss structure is simple and can be flexibly arranged in the pedestrian passage area and loading area of ​​the lower chord of the truss system, providing space for personnel passage, control room, fire water tank, etc. on the lower chord.

[0042] (3) The placing boom fixing device uses pressure plates and bolt rods to clamp the placing boom legs and the upper chord, so that the placing boom and the truss are reliably fixed, which is convenient for installation and dismantling.

[0043] (4) The truss system is equipped with a feeding chute to facilitate the delivery of concrete from the top steel platform to the concrete pouring operation layer, ensuring the quality of concrete pouring; the truss system is equipped with a waste channel to facilitate the transportation of construction waste from the steel platform to the ground, improving the vertical transportation efficiency of construction waste from the steel platform.

[0044] (5) The truss system is equipped with a construction elevator attachment frame. The standard section of the construction elevator is connected to the attachment frame by a rolling wall attachment to ensure that the construction elevator can safely climb to the top of the steel platform and provide convenience for construction personnel to move up and down.

[0045] This invention can effectively solve problems such as the design of the truss structure of the overall steel platform for super high-rise construction, the node connection construction of equipment and truss structure, and the installation of the truss system, ensuring the safety of the overall steel platform for super high-rise construction and the convenience of construction.
