Embodiment Construction

[0041] Taking square columns, four steel pipe supports, and four section steel supports as examples below, the present invention will be described in detail.

[0042] (1) Design of support unloading system

[0043] Due to the huge axial pressure on the lower floors of high-rise buildings, which are generally in the state of axial compression or small eccentric compression, only the vertical pressure can be considered in the calculation of support unloading.

[0044] 1. Beam end unloading support

[0045] Such as figure 1 As shown, first set up two (corner columns), or three (side columns), or four (middle column) steel pipe supports at the beam ends around the frame columns to be replaced, and install screw jacks on the supports, and the jacks will tighten the upper and lower beams end, and use this steel pipe to support part of the load of the detachable column.

[0046] The load that can be unloaded by the steel pipe support is determined according to the following calcul...

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 steel support 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 the unloading 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 ...
