Construction structure and construction method of a double-purpose long-span stiff beam

Abstract

A dual-purpose large-span stiff beam construction structure and its construction method belong to the technical field of stiff beam construction. It includes a support system, the support system includes several groups of first support components and second support components arranged at equal intervals, the first support components include a group of first tool steel pipes arranged at equal intervals, and the second support components include A group of second tool-type steel pipes arranged at equal intervals, between the adjacent first tool-type steel pipes and the second tool-type steel pipes, between two adjacent first tool-type steel pipes and between two adjacent second tool-type steel pipes The steel pipes are connected by several cross bars. In the present invention, the shaped steel beam is hoisted in sections, which reduces the risk of hoisting, facilitates the protection of structures and components, and is safer; and uses the erection of tool-type steel pipe brackets, and realizes the purpose of one frame for dual purposes through adjustable jacking; the construction method is simple The operation is easy, the integrity is good, the construction period is saved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of stiff beam construction, and particularly relates to a dual-purpose large-span stiff beam construction structure and a construction method thereof. Background technique [0002] Nowadays, there are more and more large-span buildings, and stiff concrete beam structures are mostly used in the design. Among them, the whole section hoisting is used for the installation of the steel beams. The tonnage of the hoisting equipment is large, the hoisting process is cumbersome, the operation safety is poor, and the height adjustment of the steel beams The inconvenience makes the construction site often difficult to transport section steel and hoist large-tonnage cranes in place due to site constraints, resulting in prolonged construction periods and increased construction costs. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to pr...

Problems solved by technology

[0002] Nowadays, there are more and more large-span buildings, and the design mostly adopts stiff concrete beam structure. Among them, the section steel beam is mostly hoisted in the whole section, the tonnage of the hoisting equipment is large, the hoisting process is cumbersome, and the operation safety is poor, and the elevation adjustment of the steel beam It is inconvenient, which makes the construction site often difficult to transport steel sections and hoist in place by large-tonnage cranes due to site constraints, resulting in longer construction periods and increased construction costs
