Abstract

The construction of large-span spatial truss structures faces severe challenges such as strict control of component processing accuracy, complex sectional hoisting conditions, and high requirements for synchronous sliding and unfolding. This paper studies the key technologies for the construction of large-span spatial truss structures in combination with the construction of spatial truss structures with a span of 145 meters. By integrating temporary structure design based on numerical simulation, high-precision positioning and welding deformation control, a technology for high-precision fabrication and segmented precise installation of steel trusses was formed, achieving the control target of component fabrication and installation error not exceeding 4mm. A multi-point sliding unfolding technology for large-span spatial trusses based on modular hydraulic pump sources and computer synchronous control was developed, and the synchronous jacking operation of 12 jacking points was successfully achieved, with synchronous error controlled within 10mm. By adding temporary measures, the spatial truss sliding system successfully withstood a typhoon of level 11 before the structure was formed, which is of great reference significance for similar projects.
