Problems solved by technology
During the construction of defective concrete replacement and reinforcement, the removal of defective concrete will cause redistribution of the internal force of the concrete shear wall. If the replacement position is unreasonable or the replacement width is too large, it will cause irreversible damage to the concrete shear wall, and even cause concrete shear. The wall collapsed, posing a threat to the safety of people's lives and property

Embodiment Construction
[0017] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0018] refer to figure 1 and figure 2 , the replacement method of defective concrete shear wall provided by the present invention comprises the following steps:
[0019] Step 1: divide the concrete shear wall to be replaced into several sections along the horizontal direction, and the width of each section is 200mm-500mm. In this specific embodiment, we divide the concrete shear wall to be replaced into 8 sections along the horizontal direction , the width of each section is 500mm.
[0020] Step 2: Open a hole in the first section of the concrete shear wall. If both sides of the concrete shear wall can support the formwork, you can open the hole front and back. If one side of the concrete shear wall cannot support the formwork, for example: For the outer wall, the holes can be kept open at the front and back, and only the concrete str...

The invention discloses a method for replacing a defective concrete shear wall, which comprises the following steps: dividing the concrete shear wall into several sections horizontally, opening a hole in the first section and burying a strain sensor along the story height direction, pouring concrete into the hole and Collect sensor data, then carry out concrete chiseling on the second section along the wall height and regularly collect the strain data of the previous section to calculate the accumulated concrete strain. The strain sensor is fixed on the vertical steel bar of the section, the formwork is supported, the concrete is poured, and the current sensor data is collected, and the rest of the sections are analogized in sequence. The invention is beneficial in that: by collecting the dynamic data in the replacement process of defective concrete shear walls—concrete strain, the replacement width and replacement position can be adjusted at any time, which avoids irreversible damage to the concrete shear walls, and more avoids The concrete shear wall is prevented from collapsing and the construction is safe and reliable.
Description
technical field [0001] The invention relates to a replacement method for a wall, in particular to a replacement method for a defective concrete shear wall, and belongs to the technical field of construction. Background technique [0002] With the acceleration of urbanization in our country, the construction industry is booming, and concrete materials are widely used in high-rise residential buildings. At present, concrete shear walls are mostly used in domestic high-rise residential buildings. Affected by factors such as the production level of commercial mixed supply enterprises and the quality control level of engineering construction, the strength of concrete shear walls is seriously insufficient. [0003] The defective concrete replacement and reinforcement method can well solve the defect problem of low strength of the actual concrete shear wall, but it is often found that when the concrete shear wall has a defect, the superstructure at the position of the defective con...
