Problems solved by technology

However, in the existing beam-column joint structure, there is no force transmission mechanism between the upper and lower modular steel pipe columns and the inner steel pipe connection interface, resulting in low rotational stiffness of this type of joint, and poor lateral stiffness of the entire building. Therefore, in practice, this The number of floors of modular steel structure buildings is less

Abstract

The invention discloses a connection structure for beam column nodes of a module-assembly-type building. The structure can be applied to corner nodes, mid-side nodes and mid nodes of module-assembly-type beam column nodes. The structure greatly improves the rotation rigidity of the beam column nodes and helps to enhance constraint for column ends, thereby lowering the coefficient for effective length of columns. The columns with the same cross section have higher stable bearing force, and accordingly the lateral load resistance capacity and integrality of the module-assembly-type steel structure building are improved.

Description

technical field [0001] The invention relates to the technical field of assembled building structures, in particular to a beam-column joint connection structure of a modular assembled building. Background technique [0002] my country is currently vigorously promoting prefabricated buildings, so this type of buildings has received more and more attention in recent years. Modular prefabricated building is a structural form with the highest degree of prefabrication in prefabricated buildings. The unit modules of this type of building are first prefabricated in the factory and the internal pipeline layout and decoration are completed, then they are transported to the site, hoisted and assembled, and finally the entire building is built. Modular prefabricated buildings are more suitable for schools, hospitals, hotels and other buildings with regular unit shapes. The assembly rate of modular prefabricated buildings is high. Practice and research have shown that such buildings ca...
