Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art road and bridge projects often use vernier calipers to measure the diameter of the steel bars when measuring the diameter of the steel bars used in construction projects. The diameter measurement steps are cumbersome, and the requirements for the quality of the measuring personnel are high. This method of measuring the diameter of steel bars is not conducive to the promotion of the problem. A road and bridge engineering supervision with steel bar diameter measuring pliers is proposed.

Abstract

The invention discloses steel bar diameter measuring pliers for road and bridge engineering supervision, and relates to the technical field of bridge engineering. The steel bar diameter measuring pliers comprises a shell, a fixed vertical plate is fixedly connected to the middle of the bottom of the shell, a supporting rod is fixedly connected to the middle of the top of the fixed vertical plate,a graduated scale is fixedly connected to the top of the supporting rod, and an incomplete gear is rotatably connected to the middle of the fixed vertical plate; after the claws of the measuring pliers are used for a long time, the inner wall surface is rusted to be uneven; when the clamping pliers are used for measuring the diameter of a steel bar, a large error can be caused, and at the moment,the clamping jaws need to be polished or replaced, the bayonet locks are pulled upwards to drive the protruding rods to move upwards to force movable rods to slide along the outer edges of connectingblocks, and the movable rods force clamping rods to rotate along horizontal connecting rods, therefore the clamping jaws can be easily separated from the connecting blocks. And the inner wall of the disassembled clamping jaws can be conveniently polished or replaced with new clamping jaws.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a steel bar diameter measuring pliers for road and bridge engineering supervision. Background technique [0002] Steel bar refers to steel for reinforced concrete and prestressed reinforced concrete. There are many types of steel bars, which are usually classified according to chemical composition, production process, rolling shape, supply form, diameter, and use in structures; steel bars currently on the market Although the types are diverse, the shape of each steel bar is fixed, thus ensuring the rationality of using steel bars in the civil engineering process. In the production process of steel bars, the quality inspection of steel bars is particularly important, and the diameter of steel bars The size is the most intuitive standard for the quality of steel bars. [0003] When measuring the diameter of steel bars used in construction projects in existing road and b...
