Beam-beam connecting node structure

Abstract

The invention discloses a beam-beam connection node structure which comprises a plurality of prefabricated wall panels and is characterized in that a splicing seam is left between each two prefabricated wall panels, and micro-expansion mortar is filled in the splicing seams; and cast-in-situ grooves are formed on the prefabricated wall panels, welts are welded in the cast-in-situ grooves, the splicing seam between each two prefabricated wall panels is a connecting section of beams, dense stirrups are arranged in the splicing seams, and the stirrups can connect the two prefabricated wall panels into a whole by welding through the welts. The micro-expansion mortar is filled in a beam-beam node, and the two wall panels are connected into the whole by welding through the welts, thereby increasing the firmness of the node, having higher mounting precision, higher construction precision and fast construction, reducing the cost of a construction formwork and the construction cost, having simple structure, clear force transfer and fast construction, facilitating the strengthening and the transformation of a construction structure and being extensively applicable to main beam connection of middle and high-rise buildings.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to a connection node structure between beams in a steel structure building. Background technique [0002] In the field of construction, the reinforced concrete column and the reinforced concrete beam or the beam-column joint of the reinforced concrete beam should be rigidly connected, and the longitudinal reinforcement of the beam should extend into the column joint, and the anchorage requirements of the steel bar should be met. The section type of the section steel in the column and the configuration of the longitudinal reinforcement should facilitate the penetration of the longitudinal reinforcement of the beam. The design should reduce the number of the longitudinal reinforcement of the beam passing through the steel column in the column, and it is not suitable to pass through the flange of the section steel, nor should it be in contact with the section steel in the co...

AI Technical Summary

Problems solved by technology

[0004] At present, the construction of the joints between beams and beams is relatively complicated. In order to meet the rigidity requirements of beams and columns, welding or bolt welding is mainly used, and the ends of steel beams are consolidated on the end plates. The connection method that runs through the rectangular steel tube concrete column, however, these methods are relatively complicated to construct and costly
