Prefabricated steel-concrete combined beam-column joint structure and its implementation method

Abstract

The invention discloses an assembly type steel-concrete combined beam column joint structure and an implementation method thereof. The assembly type steel-concrete combined beam column joint structure comprises concrete structures, a steel structure and steel-concrete combined sections. Each concrete structure comprises concrete and steel bars. The steel structure comprises short steel beams, short steel columns, reinforced ribs and connectors. Each steel-concrete combined section comprises concrete, steel bars, reinforced ribs, shear keys, prestress cables, anchor systems, an upper steel flange plate I, an upper steel flange plate II and a lateral steel end plate, wherein the shear keys are evenly and symmetrically welded to the inner side surface defined by the upper steel flange plate I, the upper steel flange plate II and the lateral steel end plate. The prestress cables are linearly arranged in the concrete structures and the steel-concrete combined sections. The short steel beams and the short steel columns of the steel structure are connected through bolts or in a welding mode, and the steel structure is wrapped with a concrete protective layer. According to the assembly type steel-concrete combined beam column joint structure and the implementation method thereof, the use amount of steel, and the anti-corrosion, fire protection and later-period maintenance cost are reduced, the problem of wet joints in construction of a prefabricated assembly concrete structure is solved, and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to an assembled steel-concrete combined beam-column node structure. Background technique [0002] At present, my country's construction industry is still a labor-intensive traditional industry with relatively backward construction methods. Therefore, it is urgent to transform and upgrade the traditional construction industry and actively promote prefabricated building structures. The existing prefabricated building structures are mainly steel structures, but other Mainly used for public buildings, the application range is limited, and the construction cost of the steel structure is high, the anti-corrosion and fire prevention treatment technology is difficult, and the maintenance cost after delivery is high; compared with the steel structure, the traditional concrete structure has a wide range of applications, mainly using cast-in-place This construction m...

Problems solved by technology

The so-called prefabricated concrete structure is based on the industrial production method, and all or part of the components in the building structure and building interior are constructed by assembly. Therefore, the key to promoting the prefabricated concrete structure is how to effectively solve the problem of parts The connection problem of components. The components of the existing prefabricated concrete structure mainly use wet joints. Compared with the cast-in-place precast concrete structure, the construction progress has been improved, but the quality of the wet joints is difficult to guarantee, and the prefabricated assembly rate is low. Limited room for improvement
