Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0035] Such as Figure 1-Figure 4 As shown, a replaceable self-resetting assembled connection node is mainly composed of prefabricated steel tube concrete column 1, prefabricated beam 2, energy dissipation steel bar 3, end plate 5, anchor plate 6, steel sleeve 9, longitudinal steel bar 8, stiffener 10, prestressed tendon 11 and stirrup 12 are formed. The joints along the height of the prefabricated steel pipe concrete column 1 are arranged in the floor, and pass continuously in the beam-column node area, and the prefabricated beam 2 is intermittent in the node area, and the beam end and the column side are used as the contact surface of the node connection.

[0036]Open a hole on the anchor plate 6 corresponding to the position of the longitudinal reinforcement 8 of the prefabricated beam 2, and its apertu...

Abstract

The invention relates to the technical field of steel-concrete composite structure in construction engineering, in particular to a replaceable self-resetting fabricated connecting joint and a construction method. The connecting joint comprises a prefabricated steel pipe concrete column and two prefabricated beams. The prefabricated beams are positioned on two sides of the prefabricated steel pipeconcrete column. Terminal plates are in contact with the prefabricated steel pipe concrete column. The prefabricated beams are provided with the terminal plates, steel sleeves and reinforced ribs. Rigidity of the beam ends of the prefabricated beams is improved; the condition of brittle fracture caused by plastic hinge generating at the beam end joint position under the action of an earthquake iseffectively prevented; beam columns adopt energy consumption rebars and prestressing tendons for connection, the energy consumption rebars can consume and dissipate energy during the earthquake, quickreplacement can be achieved after the earthquake; and repairing efficiency is improved; the prestressing tendons keep elasticity in the rare earthquake, and play a role of self-resetting after the earthquake. The replaceable self-resetting fabricated connecting joint and construction method achieve building industrialization, is free of welding and wet work on the construction site, and has the advantages of being excellent in earthquake resistance, environmentally friendly, excellent in component quality, convenient to construct, little in damage after the earthquake, replaceable and self-resetting.

Description

technical field [0001] The invention belongs to the technical field of steel-concrete structures in construction engineering, and in particular relates to a replaceable self-resetting assembled connection node and a construction method. Background technique [0002] More than 5 million earthquakes occur on the earth every year. Earthquakes not only cause physical and mental damage and property loss to people, but also cause people to lose their homes due to large-scale collapse or serious damage of buildings. According to the post-earthquake repair work of previous major earthquakes at home and abroad, it is found that even the post-earthquake repair of small damaged buildings is a huge project that is time-consuming and labor-intensive. Therefore, the research and development of new buildings with low damage under earthquake and rapid repair after earthquake is an important issue that needs to be solved urgently in the field of earthquake resistance. [0003] In addition, ...
