Reinforcing treatment construction method for concrete beam-column joints with different strength grades of high-rise buildings

Abstract

The invention discloses a reinforcing treatment construction method for concrete beam-column joints with different strength grades of high-rise buildings. The reinforcing treatment construction methodcomprises the following steps that setting out is conducted on a measuring base plane; 2, steel bar surface treatment is conducted, specifically, steel bars needed to be used as embedded steel bars are subjected to polishing and rust removing treatment, and then the surfaces of the steel bars are wiped cleanly; 3, chiseling and hole forming are conducted on concrete, and dabbing is conducted on the concrete; 4, drilling and clearing are conducted on the embedded steel bars; 5, the steel bars are embedded; 6; the steel bars are connected and bound; 7, formworks are erected; and 8, the concretepouring and curing are conducted. Compared with traditional treatment measures and technologies of the beam-column joints, the concrete strength at the core joints is guaranteed, the shrinkage crackat the concrete joints is reduced to some extent, the problem handling efficiency is improved, and the problem of the concrete strength at the joints is better solved; and the reinforcing treatment construction method has a certain practicality, scientificity and applicability, and can be widely used in beam-column joint core areas of complex high-rise buildings.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a construction method for reinforcement treatment at joints of concrete beams and columns of different strength levels in high-rise buildings. Background technique [0002] High-rise buildings have played an irreplaceable role in the process of urbanization, and more and more high-rise buildings have made new breakthroughs and developments in appearance and form. The grand situation requires quality assurance, and high-rise buildings will encounter many problems from design to construction. Among them, the more common situation of different strength levels of beam-column concrete will often bring some inconvenience to construction. If it is improper, it is likely to reduce the strength of concrete and affect the force of the structure. [0003] In high-rise buildings with cast-in-place concrete frame structures, in order to meet the seismic requirements, the des...

Problems solved by technology

[0004] At present, the concrete pouring of beam-column joints is a common problem in actual construction, and many projects do not pay attention to the quality of concrete pouring in the core area of ​​beam-column joints during the concrete pouring construction process. Low-grade concrete flowed into it, causing the concrete strength value of the core area of ​​the beam-column joint to fail to meet the design requirements
