The invention provides an ultra-high special-shaped outer-frame steel structure construction method which comprises the following steps: setting up a space measurement network, carrying out setting-out by adopting a GPS three-dimensional positioning system, as well as determining a plane control network and a high-rise control network by adopting a full-automatic total station and a precise level,so that the precise node control of a special-shaped outer-frame steel structure can be ensured; mounting a core tube close to the ground and the outer-frame steel structure; mounting an overall steel platform mold base and arranging a selected tower crane on the overall steel platform mold base; hoisting an outer-frame steel pipe column; sequentially hoisting oblique vertical columns in place byadopting the tower crane; arranging radial temporary supports between the core tube and inner-ring steel columns; sequentially hoisting ring beams in place by adopting the tower crane; after a circleof steel structures are mounted in place, correcting the positions of all control nodes; welding the steel structures; dismounting temperature connecting plates; pouring concrete into the outer-framesteel pipe column; constructing outer-frame steel beams; dismounting the radial temporary supports; and repeating the above steps. Through the ultra-high special-shaped outer-frame steel structure construction method, the efficient and precise construction of the ultra-high special-shaped outer-frame steel structure can be achieved.
Description
technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an installation and construction technology of a super high-rise steel structure. Background technique [0002] my country's super-high-rise steel structure construction technology and management are in the development stage in China, and the increasingly perfect construction technology and management methods are gradually in line with international standards. Since the compressive and lateral bending strength of the steel structure is very large, which is 1.5 times the strength of the concrete, the building space occupied by the steel structure is much smaller than the space occupied by the concrete, which increases the use of space. The components of the steel structure can only be installed on site after precision fabrication in the factory. Compared with ordinary concrete buildings, it avoids a large number of scaffolding during construction, and us...
