Problems solved by technology

Using the traditional segmentation scheme and on-site installation and positioning method not only requires components such as "bamboo joints" to be multi-segmented, which increases the workload of on-site welding, but also there are bound to be a large number of sporadic components that cannot be prefabricated in the factory and installed on site, prolonging the construction period. It has an impact on the cross-operation between various disciplines, seriously affects the construction progress and construction quality of the project, and restricts the quality of the steel structure itself and the coordinated development of various disciplines

Abstract

The invention discloses a segmented division and installation method of oversized and ultra-wide double-spliced composite I-shaped steel beams. According to the segmented division and installation method, Tekla steel structure modeling software is adopted to establish a three-dimensional visual model of a complex form; and through a BIM model and on the basis of combination of previous segmented division of the oversized and ultra-wide double-spliced composite I-shaped steel, additional arrangement of reinforcement plates is put forward creatively, and thus the problems that as for long-distance transportation of ultra-wide I-shaped steel, the segmented installation positioning difficulty is high, and the temporary reinforcement measure input is high are effectively solved. According to the segmented division and installation method, operability is high, the installation efficiency is high, welding deformation of a steel structure is effectively controlled, and the welding quality is ensured; and meanwhile, complex components between the pieces of double-spliced composite I-shaped steel are manufactured in a combined mode, the detailed installation process is determined, the construction efficiency of the steel structure is substantially improved, and economic benefits are improved.

Description

technical field [0001] The invention belongs to the field of production and manufacturing, and in particular relates to a super-large and super-wide double-combined combined I-shaped steel beam and a segmented division and installation method. Background technique [0002] For public buildings such as various large airports, railway stations, and super high-rises, it often involves the use of super-large, super-wide, and super-high section steel conversion foundations. Among them, there are extremely many ultra-large and ultra-wide double-combined I-beam transfer beam foundations. How to greatly simplify the construction process for the subsection division and installation scheme of super large and super wide double combined I-beam beams. Using the traditional segmentation scheme and on-site installation and positioning method not only requires components such as "bamboo joints" to be multi-segmented, which increases the workload of on-site welding, but also there are bound...
