Embodiment Construction

[0034] It should be pointed out that the following detailed description is exemplary and intended to provide further explanation to the present application. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] Such as Figure 1-Figure 12 As shown, the present invention discloses a modular self-resetting concrete frame low-damage joint structure of energy-consuming parts. The idea of ​​the invention is to pre-embed a strip steel part at the end of a prefabricated reinforced concrete beam on the basis of a prestressed assembled joint. Prefabricated steel sleeves, pre-embedded connecting steel plates on prefabricated reinforced concrete columns, and setting mild steel dampers on both sides of the steel web, using the low yield a...

Abstract

The invention provides a low-damage joint of assembled self-resetting concrete frame with modular energy consumption parts, including prefabricated reinforced concrete columns, prefabricated reinforced concrete beams, pre-embedded steel plates at column ends, pre-embedded shaped steel sleeves at beam ends, and soft steel damping device, unbonded prestressed steel strand, prestressed steel strand channel, high-strength hinged hole bolts; one side of the embedded steel plate at the column end is the anchor end, and the other side is the butt plate at the column end; the embedded section steel at the beam end The inner wall of the steel sleeve is welded with a shear key, and the steel web at the beam end is the butt plate at the beam end. The mild steel damper is arranged at the steel web at the beam end, fastened on both sides of the web by high-strength reamed hole bolts, and the beam-column components are connected by prestressed steel strands.

Description

technical field [0001] The invention relates to an assembled self-resetting concrete frame low-damage node, in particular to an assembled self-resetting concrete frame low-damage node with modularized energy consumption parts. Background technique [0002] my country's prefabricated structure mainly adopts the prefabricated integral type, that is, the theoretical model of "equivalent to cast-in-place". The seismic performance of the assembled monolithic structure is close to that of the cast-in-place structure, but the joints still need to be cast-in-situ, and the degree of assembly is not high. The post-tensioned prestressed prefabricated structure formed by splicing prefabricated components through prestressed steel strands not only facilitates construction, but also can withstand the bending moment at the beam end during the use stage. The residual deformation is greatly reduced, and the repair cost and indirect loss of the post-earthquake structure are greatly reduced. ...
