A unilateral prestressed fully assembled self-resetting steel frame joint

Abstract

The invention discloses a unilateral prestressed fully assembled self-resetting steel frame node, which includes H-shaped steel columns, H-shaped steel beams, energy-consuming parts and connecting parts. The connecting parts include end plates, groove-shaped connectors, prestressed steel Stranded wire and anchor plate, the end plate is hinged on the flange plate of the H-shaped steel column; the end of the flange plate of the H-shaped steel beam and the end plate are connected by energy-dissipating parts; On both sides of the web of the beam, the two ends of the prestressed steel strand are respectively anchored to the anchor plate and the groove bottom of the groove connector. The connection node of the present invention does not need to go through the core, and will not weaken the column; and the prestressed steel strand of the present invention is fixed in the H-shaped steel beam through a groove-type connector, which avoids the additional force of the prestressed steel strand on the steel column. the bending moment. Fully assembled, factory prefabricated and then transported to the site for diameter assembly, reducing labor costs and reducing the danger of high-altitude operations.

Description

technical field [0001] The invention belongs to the technical field of earthquake prevention and disaster reduction of building structures, and relates to a self-resetting steel frame node, in particular to a unilateral prestressed fully assembled self-resetting steel frame energy-consuming connection node. Background technique [0002] The self-resetting structure focuses on damage control and reducing post-earthquake economic losses, and belongs to the frontier field of earthquake prevention and disaster reduction of building structures. It has the advantages of dissipating seismic energy and reducing seismic action, reducing or avoiding damage to the main structure and minimizing residual deformation of the structure. It meets the needs of national economic development and the owner's requirements for the seismic performance of the structure. It can easily achieve the anti-seismic fortification goal of "not damaged by small earthquakes, repairable by moderate earthquakes...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the existing technology, the purpose of the present invention is to provide a unilateral prestressed fully assembled self-resetting steel frame node, which solves the problem of weakening the column caused by the core penetration of the existing self-resetting node, and the need for on-site high-altitude operations and tensioning. A series of technical and construction issues
