Abstract

The invention protects an installation method of an umbrella-shaped roof structure, aiming at the technical problems that the umbrella-shaped roof structure has complex shapes, a large number of components, difficulty in high-altitude assembly, and high precision requirements, which lead to inconvenience in the existing installation and construction methods. The construction technology field of large-scale space structures in construction engineering; the umbrella-shaped roof is divided into 20-30 umbrella-shaped unit structures, and the adjacent umbrella-shaped unit structures are connected by long strips of wavy roof steel beams. As a whole, the installation method includes the following steps: (1) Ground modular assembly; (2) Temporary support installation; (3) Sub-unit hoisting; (4) Temporary support removal and structural deformation monitoring: including sandbox support unloading, Temporary support removal and structural deformation monitoring. The installation method of the invention effectively shortens the construction period, improves the construction accuracy, and also improves the installation quality of other related structures attached to the umbrella roof structure.

Description

Technical field [0001] The present invention relates to the construction technology of large spatial structures of construction engineering, and Background technique [0002] There are more and more demand for large spaces in public buildings, and the application of large spatial structures is getting wider. The construction of large spatial structures and the techniques used in the technology often reflect the level of national building technology, some large-scale, new form, technology advanced extensive large spatial structure has become an important sign of a national economic strength and construction technology. In the past few decades, the profile steel structure has achieved breakthrough in structural form, material, design method and construction process, in some major, especially the iconic engineering, all of which Application of spatial structure. [0003] The umbrella hood structure is a form in a large spatial structure, and its structural space is complex, and the ...
