Pier column protective layer thickness detection adjusting device

Abstract

The invention discloses a pier column protective layer thickness detection adjusting device, which comprises a detection unit hung on a tower crane hook and a mobile terminal used for operating the detection unit, and through the arrangement of the detection unit and the mobile terminal, constructors can directly detect the thickness of a pier column protective layer on the outer side of a reinforcement cage, so that the construction difficulty is reduced, the construction efficiency is improved, meanwhile, the personal safety of constructors can be guaranteed, precise centering of a distance measuring sensor can be achieved through arrangement of a limiting arm, an electronic level meter, a pressure sensor, a detection rod, an electromagnetic brake and an adjusting sliding table, and the accuracy of protective layer thickness detection is guaranteed; a laser indicator can prompt constructors to perform targeted adjustment on a main reinforcement or template, the construction difficulty is further reduced, the detection unit can be adapted to detection of different pier columns and different reinforcement cages, and the universality of the equipment is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction detection equipment, in particular to a detection and adjustment device for the thickness of a pier column protective layer. Background technique [0002] The national standard GB50204-2002 "Construction Quality Acceptance Code for Concrete Structure Engineering" stipulates that the allowable deviation range of the thickness of the concrete cover is -7~+10mm for beam members and -5~+8mm for slab members. [0003] According to the regulations, the thickness of the protective layer is "the thickness of the concrete protective layer calculated based on the outer edge of the outermost reinforcement (including stirrup 22, structural reinforcement, distribution reinforcement, etc.)". [0004] The regulation of the minimum thickness of the protective layer is to meet the durability requirements of the concrete structural members and the requirements for the effective anchoring of the stressed...

AI Technical Summary

Problems solved by technology

[0007] The existing method of measuring the thickness of the protective layer of pier columns needs to be carried out by hoisting the construction personnel into the steel cage. The construction is difficult and the construction efficiency is low. High, the exact value of the thickness of the protective layer of the pier column cannot be obtained
