Abstract

The invention provides a construction method of a suspension steel structure. The construction method comprises the steps that according to the preset positions and preset specifications of temporary diagonal tension braces of all floors obtained in advance, cantilever steel beams and the temporary diagonal tension braces of all the floors are installed layer by layer from bottom to top; according to the preset positions and preset specifications of temporary supports obtained in advance, the temporary supports used for supporting a top-layer cantilever steel truss are installed on the top faces of the cantilever steel beams of the topmost floor; the top-layer cantilever steel truss is installed above the cantilever steel beams located on the topmost floor to form a stable frame; hanging columns are installed on the top faces of the cantilever steel beams of all the floors layer by layer from top to bottom; and after all the hanging columns are installed, the temporary supports and the temporary diagonal tension braces are unloaded. According to the construction method, the stress requirement of the hanging columns can be met, construction is safe and controllable, the construction quality and precision can meet the design requirement, the construction efficiency is improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of steel structure engineering construction, in particular to a construction method for hanging a steel structure. Background technique [0002] In the field of long-span steel structure urban pavilion construction, the installation of suspended steel structures has always been a major problem in the construction field. Suspension steel structure is usually set on the periphery of the main structure to meet the space requirements of the lower part or create a special facade architectural form. The suspended steel structure is usually provided with a cantilevered steel truss on the top floor, and the cantilevered steel beams below are suspended by hanging columns or tie rods to form a floor structure. If the hanging columns or tie rods have a certain inclination angle, the The stress system of the above-mentioned cantilevered steel beams will be more complicated, and the requirements for construction precisi...
