Abstract

The invention discloses a novel support-free shear wall concrete replacing device and a novel support-free shear wall concrete replacing method. The shear wall concrete replacing device comprises an upper structure, a lower structure and a placing area located between the upper structure and the lower structure. The replacing area comprises an original wall and a replacing wall. The replacing walland the original wall are adjacent. Vertical vibrating wire strainometers are arranged on the replacing wall and the original wall, and a stress conversion jack is arranged on the top of the replacing wall. The shear wall concrete replacing method comprises the following steps: dividing a shear wall needed to be replaced into a plurality of sections, replacing the shear wall sections one by one and measuring variations of stresses of the walls in a construction process by the vibrating wire strainometers; and then applying a pressure by the stress conversion jack, wherein the inner stresses of the walls are converted into designed values to make sure the structure is safe. The device is simple and the method is simple and convenient, and the device and the method solve the problem of stress differences among the replacing walls in the prior art effectively.

Description

technical field [0001] The invention relates to a novel unsupported replacement shear wall concrete device and method. Background technique [0002] The replacement concrete reinforcement method is a common reinforcement method used to deal with the low strength or serious defects of concrete structures. The commonly used replacement concrete reinforcement method is the supported replacement method. However, in high-rise concrete shear wall structures, when the shear wall concrete to be replaced is on the bottom floor, due to the large load, the support during the replacement construction process is quite difficult, expensive, and has safety risks. Unsupported replacement reinforcement technology can solve this problem, but it brings the problem of stress hysteresis. In the unsupported replacement shear wall concrete reinforcement project, the vertical stress hysteresis phenomenon exists in the post-replacement wall section compared with the first-replacement wall section....
