The invention relates to the field of assembly type steel buildings, in particular to an assembly type steel beam-column mortise and tenon joint type joint structure and an assembling method. The structure comprises orthogonal beams A, upper grooves, reinforced ring engagement keys, orthogonal beams B, lower grooves, reinforced rings, reinforced ring engagement key grooves, mortise and tenon joint steel pipes, mortise and tenon joint steel pipe grooves, mortise and tenon joint steel pipe groove reinforced angle steel, connection steel beams, steel beam reinforced angle steel, flanges and web plates which form a mortise and tenon joint connection joint combined frame, each frame is composed of eight mortise and tenon joint connection joints, the vertical directions of the joints are connected through the mortise and tenon joint steel pipes, and the transverse directions of the joints are connected through the connection steel beams. According to the assembly type steel beam-column mortise and tenon joint type joint structure and the assembling method, factory prefabrication and site operation requirements are comprehensively considered, and connection among the orthogonal beams and the mortise and tenon joint steel pipes and the reinforced rings is achieved; actual engineering design and construction needs are met, the welding workload is small, environmental protection and energy conservation are achieved, and the current green building requirement is better met.
Description
technical field [0001] The invention relates to the field of prefabricated steel structure buildings, in particular to a beam-column mortise and tenon joint structure and an assembly method of the prefabricated steel structure. Background technique [0002] Prefabricated buildings have the advantages of environmental protection and fast construction speed, and become one of the important directions of future building development. The prefabricated steel structure is one of the important components of the prefabricated building. In the past, in the prefabricated steel structure, the beam-column joints were mainly connected by welding, and the force between the beams and columns was transmitted by the weld. This kind of joint has many disadvantages, such as: high welding quality requirements, complex construction, large welding quality affected by human factors, large residual stress in the weld and around the weld, and the seismic performance is greatly affected by the weld. ...
