Positioning frame for prefabricated pier column reinforcing bar cages and construction method of pier column reinforcing bar cages

Abstract

The invention discloses a positioning frame for prefabricated pier column reinforcing bar cages and a construction method of the pier column reinforcing bar cages, and belongs to the technical field of construction of municipal works. The positioning frame disclosed by the invention can accurately position the positions of main reinforcing bars in pier column reinforcing bars and the positions of hoop reinforcing bars in the pier column reinforcing bars, and a reinforcing bar framework is rapidly and accurately manufactured; during manufacturing of the reinforcing bar framework, bearing platform reinforcing bars are manufactured, and steel plates are arranged on the bearing platform reinforcing bars; control points are arranged on the steel plates to accurately position the reinforcing bar framework. The positioning frame and the construction method disclosed by the invention have great superiority; the bearing platform reinforcing bars and the pier column reinforcing bars can be in line production in parallel; the positions of the main reinforcing bars in the pier column reinforcing bars and the positions of the hoop reinforcing bars in the pier column reinforcing bars are accurately controlled and are convenient to control, so that the construction schedule and the project quality can be doubly increased; the construction safety is guaranteed; after the prefabrication is completed, the reinforcing bar framework is integrally hoisted, so that the time for working high above the ground and crane working is shortened, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of municipal engineering construction, in particular to a positioning frame for a prefabricated pier column reinforcement cage and a construction method for a pier column reinforcement cage. Background technique [0002] The steel bar protective layer refers to the distance from the outer edge of the outermost steel bar to the concrete surface. If the steel bar protective layer is too thick, the bearing capacity of the component will be reduced; if the protective layer is too small, the intrusion of moisture in the air will cause the steel bar to corrode and affect the adhesion between concrete and steel bar. Knot grip wrap, reduce the bearing capacity of the component. [0003] There are different degrees of dimensional deviation and inaccurate positioning in the processing of pier column steel bars, which lead to unqualified steel bar protection layer, which leads to problems such as steel bar corrosion an...

Problems solved by technology

[0002] The steel bar protective layer refers to the distance from the outer edge of the outermost steel bar to the concrete surface. If the steel bar protective layer is too thick, the bearing capacity of the component will be reduced; if the protective layer is too small, the intrusion of moisture in the air will cause the steel bar to corrode and affect the adhesion between concrete and steel bar. Knot and wrap, reduce the load-carrying capacity of the component

[0003] There are different degrees of dimensional deviation and inaccurate positioning in the processing of pier column steel bars, which lead to unqualified steel bar protection layer, which causes problems such as steel bar corrosion and pier column bearing capacity decline, which seriously affects the service life of structures
