Device and construction method suitable for adjusting protective layer of bridge pier column reinforcement

Abstract

The invention discloses a device and a construction method suitable for adjusting a protective layer of a bridge pier column reinforcement. The device suitable for adjusting the protective layer of the bridge pier column reinforcement is arranged in a bridge pier column construction position; in the bridge pier column construction, steel reinforcement cages and a steel template are arranged in the bridge pier column construction; the steel template is horizontally arranged; the multiple steel reinforcement cages are arranged in an equally spaced manner; the steel reinforcement cages are perpendicular to to the steel template; the device suitable for adjusting the protective layer of the bridge pier column reinforcement is arranged at one end of the steel template and comprises a manual steel wire rope winch, a hand-cranking rod, a steel wire rope and a winch hook, wherein a bolt hole is formed in one end of the steel template; the winch hook hooks the bolt hole; one end of the steel wire rope is connected with the winch hook; the other end of the steel wire rope is wound on the manual steel wire rope winch; the hand-cranking rod is mounted in the central position of the manual steel wire rope winch; by pressing down the hand-cranking rod, the steel wire rope is enabled to drive the steel reinforcement cages to move to one side of the manual steel wire rope winch, and cushion blocks are additionally mounted on the steel reinforcement cages to adjust the steel reinforcement cages. The device suitable for adjusting the protective layer of the bridge pier column reinforcement has the advantages that the structure is simple, the implementation cost is low, the device is safe, convenient and fast, and the occurrence rate of engineering accidents can be reduced.

Description

technical field

[0001] The invention relates to the field of steel bar construction for bridge pier columns, in particular to an adjusting device and a construction method for a steel bar protective layer of bridge pier columns. Background technique

[0002] The diameter of the steel bars of the bridge piers is relatively large. No matter what form of piers, the steel bars are biased and the protective layer is not enough. It takes a lot of force to move the steel bars. The most common way to adjust the protective layer is to use a crowbar directly to open it, and use a crowbar to open it. If the crowbar slides on the steel bar, the worker's center of gravity will easily become unstable, and it is easy to fall from a height. mold or scaffolding, causing a safety accident. The hoist is also used to pull the steel cage, but the hoist cannot be directly tied to the scaffolding, so as not to affect the stability of the frame, and a fixture must be found on the ground. If it is...
