Example Embodiment

[0033] The present invention will be further described in detail below in conjunction with the drawings.

[0034] Such as Figure 1-10 As shown, the plug-in modular steel structure connection node with the reset function includes a modular steel structure connection node and a self-resetting armpit 11. The modular steel structure connection node includes two upper module units, two lower module units, a cross-type plug connector 7, a vertical cover plate 8, a horizontal cover plate 9 and a high-strength bolt 10. The upper module unit includes upper box section module column 1, upper I-section module beam 2, upper channel section module beam 3, upper I-section module beam 2 and upper channel section module beam 3 are welded vertically to the upper box On the adjacent side surface of the end of the module column 1 with section; the lower module unit includes lower box section module column 4, lower I-section module beam 5, lower channel section module beam 6, and lower I-section mo...

Abstract

The invention relates to an inserting type modular steel structure connecting joint with a reset function. The inserting type modular steel structure connecting joint comprises a modular steel structure connecting joint body and self-reset haunch supports, wherein the modular steel structure connecting joint body comprises two upper module units, two lower module units, a cross-shaped inserting pin connecting piece, a vertical cover plate, a horizontal cover plate and high-strength bolts, and the four self-reset haunch supports internally provided with disc springs are symmetrically arranged at the corner parts of the joint body and are hinged to module beam columns. According to the inserting type modular steel structure connecting joint, module units are connected through the cross-shaped inserting pin connecting piece, the cover plate and the high-strength bolts, so that it is guaranteed that the joint has enough tensile strength, shear strength and bending strength, a connecting device has no need occupying the use space of a building, the application range is wide, and meanwhile attractiveness is guaranteed; and the arrangement of the self-reset haunch supports can improve thebearing capacity of the joint, delay degradation of the rigidity and strength of the joint, reduce damage to the joint beam-column intersection, avoid premature damage to components, achieve rapid repair and guarantee stability and reliability of the joint performance, and residual deformation after an earthquake is small.

Description

Technical field [0001] The invention belongs to the technical field of modular buildings, and specifically relates to a self-resetting connection node applied to a modular steel structure. 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 the quality of the project. Construction waste and noise generated during the construction process 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 mode of the traditional construction industry to the large-scale industrial production mode. The realization of standardization of ...
