Layered hoisting construction process for suspended steel structure

Abstract

The invention designs a layered hoisting construction process for a suspended steel structure, comprising a truss structure and a spherical pod structure in a space structure below a truss. The layered hoisting construction process is characterized by comprising the following steps of: erecting a high-altitude temporary support moulding bed on the ground of the space structure below the truss; mounting a pod structure on the temporary support moulding bed by using a high-altitude spread method; tensioning a high-strength span wire; mounting the pod structure to be in place and then mounting and tensioning the high-strength span wire; dividing the whole tensioning process into three phases, namely initial pre-tightening and tensioning before unloading a temporary support, tensioning after mounting and unloading the structure and tensioning after mounting a permanent load to be in place, for construction; and downwards staying the pod structure by using a stabilization cable. The invention has the advantages that the suspended steel structure is mounted by adopting a method for erecting a layered separate temporary support system and the problems of positioning of the structure space and the structure stabilization in the mounting process are solved.

Description

technical field [0001] This process belongs to the field of construction engineering structure, and is a large-scale suspended steel structure construction process using high-strength suspension cables as the main force-bearing system. Background technique [0002] The steel structure of the Shanghai Port International Passenger Transport Center Project Music Culture Center is about 50m south of the Huangpu River. The span of the entire structure is 48.4m in the east-west direction, 30.4m in the north-south direction, and the building height is 53.6m. The entire structure consists of independent vertical steel frames on both sides and an inclined frame in the middle to form the core force supporting system of the entire structure. The top of the structure is a large-span truss system. Three irregular spherical pods are suspended inside the steel frame structure, which is a suspended steel structure.

Problems solved by technology

[0003] As a landmark building in the construction of Shanghai Port International Passenger Transport Center, the project has many components and structural units, and its stress state is complicated. In particular, the steel structure of the gondola suspended by high-strength suspension cables is used. As a brand-new structural system, its The complexity poses great challenges to the design, processing and installation of steel structures
