Steel corbel cut column connecting structure and construction method

Abstract

The invention provides a steel corbel cut column connecting structure and a construction method, the steel corbel cut column connecting structure comprises a concrete column and a steel corbel, the upper column side wall and the lower column side wall of the to-be-cut surface of the concrete column are each provided with a plurality of first mounting holes, the first mounting holes are through in the radial direction of the concrete column, and bent screw rods are mounted in the first mounting holes; the bent screw is bent towards the cross section of the concrete column, the steel corbels are symmetrically arranged on the two side walls of the concrete column, second mounting holes corresponding to the first mounting holes are formed in the steel corbels, the two ends of the bent screw penetrate through the second mounting holes and are fastened to the steel corbels, and the first mounting holes and the second mounting holes are filled with grouting materials. In the jacking or deviation rectifying project, the lifting force applied to the steel corbel by the jacking mechanism is balanced by the tensile force provided for the bent screw rod, the bent screw rod is mainly subjected to the tensile force effect, the stress distribution is relatively uniform relative to the concrete in contact with the penetrating straight screw rod (embedded steel bar), and the condition that the concrete at the end part of the bent screw rod is crushed in the actual project is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a connection structure and construction method of a steel corbel cut-off column. Background technique [0002] Building building has the advantages of not occupying land, less investment, quick results, and can quickly solve the problem of housing shortage. It is especially suitable for my country's national conditions. Therefore, in recent years, my country has carried out a large number of old building building renovations, and achieved good economic benefits and benefits. successful. The inclination and successive collapse of some ancient buildings forced people to take various measures to protect the existing monuments and cultural relics; new buildings (structures) were tilted due to improper foundation treatment or other reasons, forcing people to pay attention to building rectification technology, to reduce economic losses. [0003] The steel corbel truncate...
