Rotten root prevention construction method for shear walls, columns and other concrete vertical structures

Abstract

The invention discloses a rotten root prevention construction method for shear walls, columns and other concrete vertical structures. The method comprises the steps of 1 formulating a formwork project construction scheme, 2 fitting a die, 3 determining shear wall and column side boundaries, and performing paying-off along the shear wall and column side boundaries, 4 performing cutting along the shear wall and column side boundaries and chiseling a groove, 5 installing shear wall and column root backform reinforcing steel bars, 6 inspecting and finishing a formwork, and uniformly coating an oil releasing agent, 7 installing the formwork, 8 inspecting the perpendicularity and flatness of the formwork and accepting the formwork, 9 straightening an outer wall external formwork, staircases, elevator shaft formworks and lower wall suspension wires, 10 plastering the formwork root with cement mortar and pouring concrete, and 11 removing the formwork. According to the rotten root prevention construction method for shear walls, columns and other concrete vertical structures, the rotten root phenomenon of the shear walls, columns and other concrete vertical structures is eliminated, the appearance quality of a finished product is improved, the durability is good, following repairing procedures are avoided, and the time limit for a project is shortened.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for preventing and controlling root rot of concrete vertical structures such as shear walls and columns. Background technique [0002] In the construction of high-rise buildings, concrete vertical structures such as shear walls and columns are the key to the construction of the main body of the building. Due to reasons such as construction technology, materials, and technical proficiency of operators, concrete vertical structures such as shear walls and columns often have root rot, a common quality problem. In terms of the reasons for its quality defects, in addition to material and human factors, the main reason is that in the prior art, concrete vertical structures such as shear walls and columns are poured by installing construction splints after the construction of the floor concrete. For concrete vertical structures such as shear walls an...

Problems solved by technology

Due to poor contact between the formwork and the concrete of the floor slab, gaps are likely to occur. The traditional method is to use cement mortar at the root of the formwork to block the gap between the formwork and the floor after the adjustment and reinforcement is completed, and then pour the shear wall after the cement mortar has solidified. Concrete vertical structures such as columns, due to grout leakage caused by loose joints between the formwork and the ground during the construction process or concrete segregation due to irregular manual vibration, rotten roots often appear on the finished shear walls, columns and other concrete vertical structures Phenomenon, resulting in poor sensory quality and low durability of the finished product, and it needs to be repaired later, which increases the construction period and affects the durability and progress of the project
