Construction method for arranging steel corbel on concrete frame column

Abstract

The invention relates to a construction method for arranging a steel corbel on a concrete frame column. The construction method comprises the steps of assembling steel reinforcements to form a steel reinforcement framework, and fixing at least four pre-cast screws on at least one face of the steel reinforcement framework according to the designed elevation, wherein one end of each pre-cast screw and the steel reinforcements in the steel reinforcement framework are in point welding to be fixed, and the other end of each pre-cast screw is exposed out of the steel reinforcement framework; installing a formwork on the outer side of the steel reinforcement framework, wherein the portions, exposed out of the formwork, of the pre-cast screws are protected by being wound with adhesive plasters; pouring concrete in the steel reinforcement framework; after the concrete reaches the design strength, disassembling the formwork to form the concrete frame column; installing the steel corbel on the concrete frame column, wherein the steel corbel is provided with a plurality of transverse adjustable bolt holes, and the steel corbel is fixed on the pre-cast screws through bolt holes in an adjustable mode.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction method for setting steel corbels on concrete frame columns. [0002] Background technique [0003] In the process of building construction, according to the "Code for Design of Concrete Structures", for the design of industrial plants with concrete frame structures, it is necessary to set corbels at the support points of beams such as trusses, crane beams, and process tracks. [0004] However, the corbel structure on the concrete frame column in the prior art is usually formed integrally with the concrete frame column by pouring concrete. In this way, the joints where the corbels are set on the concrete frame columns need to add horizontal reinforcement stirrups and bent steel bars. On the one hand, the joints will have dense reinforcement and concrete pouring will be difficult, and even the concrete at the joints will not be compacted by vibration, expose...

AI Technical Summary

Problems solved by technology

In this way, the joints where the corbels are set on the concrete frame columns need to add horizontal reinforcement stirrups and bent steel bars. On the one hand, the joints will have dense reinforcement and concrete pouring will be difficult, and even the concrete at the joints will not be compacted by vibration, exposed bars, and numb. surface and other defects; on the other hand, the production of special-shaped formwork is complicated, which reduces the work efficiency

Especially in the case of setting corbels on three and four sides of the concrete frame column, the defect is more serious, and it is also more unfavorable for construction
