Method for reinforcing integral replacement concrete for high-rise building steel bar concrete column

Abstract

The invention discloses a method for reinforcing integral replacement concrete of a high-rising building steel bar concrete column, and aims to solve the problem that unqualified steel bar concrete frame column can not be effectively treated by the prior replacing concrete reinforcing method under a condition that the frame concrete columns endure huge load. The method comprises the following steps: mounting an unloading support on the beam end on the periphery of a replaced column; dividing the replaced column into a plurality of parts; manually removing concrete and mounting a profile steelsupport in sequence; welding a batten plate on the profile steel support to form a structural batten plate column; building concrete on the position of the original replaced column; and detaching theunloading support on the edge of the column. The method can perform integral replacement on the unqualified column of the high-rise building, has small economic loss without affecting the appearance and use functions of the building, need not stop construction for the upper building during construction, and can not cause adverse affect on commercial housing and disturb the selling of the commercial housing.

Description

technical field [0001] The invention belongs to the technical field of construction, and specifically relates to a reinforcement method for integrally replacing reinforced concrete columns of high-rise buildings. Background technique [0002] For reinforced concrete frame structures, frame-shear structures, and frame-tube structures, the quality of concrete engineering is the key to ensuring building safety. However, in actual engineering, due to the influence of various factors, concrete engineering is more prone to engineering quality accidents, especially the strength of concrete. If the difference between the concrete strength level and the design requirements during construction is small, the reinforcement problem is relatively easy to deal with. What is discussed here is how to carry out frame column replacement and reinforcement treatment when the strength grade of concrete is quite different from the design requirements. Since commercial concrete is basically used ...
