Protection layer thickness control method in pier column construction process

Abstract

The invention relates to the technical field of building construction methods, in particular to a protection layer thickness control method in the pier column construction process. The method comprises the following steps: 100, accurately setting out a pier column according to the design size and position of the pier column, marking longitudinal and transverse axes of the pier column, and positioning pier column reinforcing reinforcements; 200, arranging clamps outside pier column reinforcement samples above a pier column bearing platform in a surrounding mode, and positioning the pier columnreinforcements; 300, accurately inserting the pier stud reinforcing reinforcements according to the positions of the clamps; 400, binding the pier column reinforcing reinforcements, setting a cushionblock and erecting a pier column template; and 500, pouring bearing platform concrete. When a pier column reinforcement cage is manufactured, the clamps are used for positioning the pier column reinforcements, the pier column reinforcement cage can be reinforced, the stability of the pier column reinforcement cage is enhanced, the pier column reinforcement cage is not prone to deviating, then thethickness uniformity of the pier column protection layer is guaranteed, and therefore the using performance and the service life of the pier column are guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction methods, in particular to a method for controlling the thickness of a protective layer during pier construction. Background technique [0002] The durability of reinforced concrete structures is largely reflected in the quality and thickness of the protective layer. The concrete protective layer (referred to as the protective layer) refers to the concrete layer between the outer edge of the outermost reinforced steel bar in the reinforced concrete member and the concrete surface. It protects the steel bar in a closed environment and maintains the strength of the steel bar and the overall structure. Stability, its thickness is one of the important factors affecting the performance of components. If the protective layer is too large, it will reduce the bearing capacity of reinforced concrete components. If the protective layer is too small, it will easily cause the surface concrete to...

Problems solved by technology

[0011] The purpose of this application is to provide a method for controlling the thickness of the protective layer during the construction of pier columns, so as to solve the problem of poor stability and offset of the reinforcement cage during the construction of pier columns in the prior art, which causes the protective layer of pier columns There is a deviation in the thickness, which affects the performance and life of the pier column.
