Beam column mortise and tenon joint type node structure of assembly type steel structure

Abstract

The invention discloses a beam column mortise and tenon joint structure of an assembly type steel structure, and the structure comprises a left tenon, a mortise and tenon groove, a steel structure column body, a right tenon, a steel structure beam body and a leveling device. Two steel structure beam bodies are placed on the leveling clamping bases on the two sides in parallel, so that the two steel structure beam bodies can be in a parallel state, the steel structure beam bodies move inwards in parallel through the leveling clamping bases, and the left tenons and the right tenons on the two steel structure beam bodies can stably stretch into the mortise and tenon grooves; the left tenon and the right tenon are connected with the tenon-and-mortise groove in an engaged mode, and therefore the stability of the beam column tenon-and-mortise type node structure is guaranteed.

Description

technical field [0001] The invention relates to the field of prefabricated steel structure buildings, in particular to a beam-column tenon-mortise joint structure of prefabricated steel structures. Background technique [0002] In recent years, the scale of China's construction industry has continued to expand, and prefabricated steel structures have been widely used. At present, there are some representative prefabricated building projects and demonstration projects in China. Prefabricated buildings have the advantages of environmental protection and fast construction speed, and become one of the important directions of future construction development. A joint connection method, the protruding part is called tenon; the concave part is called mortise, the tenon-and-mortise joint has a simple structure, high bearing capacity, easy installation, and good economic benefits. [0003] When the existing tenon-and-mortise joint is assembled, a tenon-and-mortise groove is set in th...

AI Technical Summary

Problems solved by technology

[0003] When the existing mortise and tenon joints are assembled, a tenon and tenon groove is set in the column, and the tenon of the beam is inserted into the tenon and tenon groove to realize the connection of the beam and the column. After the tenon of the two beams is inserted into the column When the mortise and tenon groove is used, the mortise and tenon heads of the two beams will be butted together inside the mortise and tenon groove. In a parallel state, if the mortises on the two beams are directly connected to the mortise and tenon grooves, the two mortises and the mortise and tenon grooves will be stuck, causing the beam column to be unable to move under the action of the mortise and mortise and tenon grooves. The joint connection makes the stability of the joint structure poor, which will become a safety hazard for the entire building. It is prone to damage under extreme conditions such as earthquakes, and its safety factor is poor.
