Abstract

The invention relates to a plug-in modular steel structure connection node with reset function, which includes a modular steel structure connection node and self-resetting arm braces; the modular steel structure connection node includes two upper module units, two lower module units, Cross-type bolt connectors, vertical cover plates, horizontal cover plates and high-strength bolts; four self-resetting arm braces with internal disc springs are symmetrically arranged at the corners of the nodes and are hinged to the module beams and columns. The present invention connects the modular units through the cross-shaped bolt connectors, cover plates and high-strength bolts to ensure that the nodes have sufficient tensile, shear, and bending rigidity, and the connecting device does not need to occupy building space, and has a wide application range while ensuring aesthetic appearance. The setting of self-resetting haunches can improve the bearing capacity of nodes, delay the degradation of stiffness and strength of nodes, reduce the damage at the intersection of beams and columns of nodes, avoid premature failure of components, and have small residual deformation after earthquakes, which can realize rapid repair and ensure node performance stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of modular buildings, and in particular relates to a self-resetting connection node applied to modular steel structures. Background technique [0002] At present, most civil buildings adopt traditional cast-in-place structures, which have a long construction period, low efficiency, high labor costs, and difficulty in ensuring project quality. Construction waste and noise generated during construction also have a certain impact on people's lives. In order to ensure the sustainable development of the construction industry, reduce environmental pollution, and improve energy utilization and labor productivity, my country is vigorously promoting green buildings and building industrialization. The industrialization of construction means the transition from the manual operation mode of the traditional construction industry to the large-scale industrial production mode. The realization of standardization of architec...
