Prefabricated assembly type beam column joint connecting process

Abstract

The invention discloses a prefabricated assembly type beam column joint connecting process. The process comprises the steps that a frame column comprising three rows of threaded sleeves is prefabricated; a pore passage is reserved in the lower end of each prefabricated frame beam, a connecting steel bar on the lower portion of each frame beam is inserted in the corresponding reserved pore passage, and a gap is kept between each frame beam and the frame column; a connecting steel bar on the upper portion of each frame beam is connected with the upper threaded sleeves, the connecting steel bar on the lower portion of each frame beam is connected with the lower threaded sleeves, and detachable supporting pieces are connected with the reinforced threaded sleeves; the reserved pore passages are filled with high-strength mortar; a prefabricated plate is hoisted and placed on each frame beam, and beam and plate laminating layers are formed in a pouring mode through concrete to complete wet joint connection. By means of the process, the frame beams on the two sides of the frame column can be connected together, the overall structural stability can be improved, no weld spot exists, high-altitude welding operation is avoided, the safety risk is lowered, and connection between the frame column and the frame beams is more stable and reliable by means of pouring of the wet joint concrete and the high-strength mortar; moreover, construction is fast, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prefabricated beam-column node connection process. Background technique [0002] The beam-column joints of reinforced concrete frame structures are also called the joint core area. Due to the complex and concentrated stress in this area, its destruction can lead to the collapse of the entire frame structure system. Therefore, the design of beam-column joints is also the focus of the frame structure. Although there are sufficient guarantee measures in the design, such as thickening and thickening the beam-column stirrups, there is no effective control measure for the binding of the beam-column joint steel bars at the construction site. Binding, insufficient quantity, indiscriminate spacing, several stirrups piled up together or a long empty section without stirrups seriously affect the safety of the structure. [0003] At present, the prefabricated beam-column joi...

AI Technical Summary

Problems solved by technology

The disadvantages of this kind of prefabricated beam-column joints are: during construction, it is necessary to strictly calculate the vertical and horizontal distribution of steel bars to avoid construction pouring that is not staggered or should be avoided in the concrete. , it is necessary to re-adjust the layout plan and re-construct, resulting in a prolonged construction period and a waste of human, financial and material resources

This connection method leads to difficult construction and low construction efficiency.
