Through bolt assembling structure for square steel binding post and square steel tubular beam

Abstract

The invention discloses a through bolt assembling structure for a square steel binding post and a square steel tubular beam, and relates to the fields of building steel structures, civil constructiontechnologies, and large cultural relic duplication, exhibition and display. The through bolt assembling structure comprises bolt connecting holes arranged in the square steel tubular beam; the connecting end of the square steel binding post is fixedly connected with end plates; each end plate is provided with bolt connecting holes cooperated with the bolt connecting holes on the square steel tubular beam; and the square steel tubular beam and the end plates are connected in a way that thread bolts penetrate through the bolt connecting holes. The through bolt assembling structure adopts full-bolt assembling, prefabricating work and welding work are both finished in a factory, so that quality is reliable, and full-bolt through connection is adopted in field. A field assembling workload is greatly reduced, meanwhile, material consumption is reduced, and the reliability of the structure is reinforced. The through bolt assembling structure has excellent anti-seismic properties, and the ductility and the energy-dissipating capacity of the structure can be obviously improved. An outward extending stiffening rib is arranged on each plate to enable a plastic hinge to move outwards so as toprevent the plastic hinge from appearing on a beam end. The through bolt assembling structure is convenient in repairing or replacement after an earthquake.

Description

technical field [0001] The invention relates to the fields of building steel structure, civil engineering technology, reproduction and display of large-scale cultural relics, and mechanical assembly, in particular to a through-bolt assembly structure of a square steel connecting column and a square steel pipe beam. Background technique [0002] The development of prefabricated steel structure buildings is one of the key points of construction industry reform in recent years. Although box columns have good resistance to bidirectional bending and torsional buckling, there is no space for bolt installation. Under the background of multidisciplinary cooperation, the application of prefabricated steel structure connection structure has been extended to the actual project of large-scale cultural relics reproduction and exhibition in the field of traditional architecture. The square steel pipe beam and the square steel connecting column structure are connected by end plate bolts. I...

AI Technical Summary

Problems solved by technology

The square steel pipe beam and the square steel connecting column structure are connected by end plate bolts. In view of the lack of relevant theories, imperfect structural design and complicated on-site operation, there is an urgent need for a structure with superior seismic performance, convenient and reliable construction, no welding on site, and quick replacement after the earthquake. and repair, a new connection structure that meets the requirements of building industrialization
