Abstract

The invention relates to the technical field of combined steel truss installation construction, in particular to a narrow-space long-span multi-surface special-shaped combined steel truss installationconstruction method. The method is characterized in that a BIM technology is utilized to optimize arcs and establish a high-level control network, and field data is finely adjusted in combination with a computer; during field construction, steel truss segments are spliced, full hall scaffold operation platforms and supporting frames are erected at building structure ends and steel truss connection parts synchronously, and a main truss is formed through assembling and welding; and then sliding units are formed through connection of secondary trusses among main trusses, and existing concrete linking beams are utilized to arrange sliding tracks, and in-place sliding is performed according to a structure accumulating sliding mode. Through the method, the quantity of scaffolds in use can be greatly reduced, the method is safe and reliable, most overhead work is reduced, construction is convenient, a machine used for lifting is relatively small, and mechanical cost is low. The method is mainly applied to the technical field of combined steel truss installation construction.

Description

technical field [0001] The invention relates to the technical field of installation and construction of composite steel trusses, and more specifically relates to a method for installation and construction of large-span multi-curved surface special-shaped composite steel trusses in a narrow space. Background technique [0002] With the development of the construction industry and the advancement of science and technology, in order to meet people's individual requirements for buildings, there are more and more types and functions of building structures. Steel structure is one of the types of building structures, and it is more and more widely used in construction engineering. The design shapes of the steel structure system emerge in endlessly. The unique shape of the design and the irregular curves of the steel truss, such as bumps, undulations, inclinations, and multi-curved surfaces, are one of the highlights of the project. The smooth completion of the internal quality and...
