Key Points for Construction Quality Control of Steel Bar Concrete Structure

Abstract

In view of the good effect of steel bars in improving the elastic-plastic and flexural properties of concrete structures, combined with the good compressive strength of concrete, steel bars in the traditional reinforced concrete column and shear wall structures can greatly improve the performance of the main stress-bearing structures of super high-rise buildings. In order to clarify the key points of construction quality control of steel bar concrete structure, the control points are analyzed by theoretical analysis method combined with an engineering example. The results show that it is feasible to replace the traditional solid web section steel with the scattered steel bars to solve the difficult problem of the layout of the stirrups and longitudinal bars of the solid web section steel reinforced concrete column, and the ear plate connection of the steel bars is feasible; BIM Technology can realize the accurate positioning of steel bars and greatly improve the construction quality of steel bar concrete structures; During the construction process, it is very important to strictly control the verticality of steel bars, the spacing between steel bars, the spacing between steel bars, the distance from the outside of steel bars to the reinforcement at the column edge, and strictly control the quality of formwork installation and concrete pouring to ensure the quality of steel bar concrete structure.
