Hardness detection device and detection method for high-strength steel bars

Abstract

The invention belongs to the technical field of building material detection, and particularly relates to a hardness detection device for high-strength steel bars and a detection method. The hardness detection device comprises a table top, a supporting frame is fixedly connected to the top of the table top, a pressure air cylinder body is fixedly connected to the bottom of the supporting frame, and a clamping ring is fixedly connected to the bottom of the pressure air cylinder body; protective covers used in cooperation with the pressure air cylinder bodies and the clamping rings are arranged on the two sides of the top of the table top correspondingly, adjusting mechanisms used in cooperation with the protective covers are arranged on the front side and the rear side of the supporting frame correspondingly, and fixing mechanisms used in cooperation with the adjusting mechanisms are arranged on the tops of the front side and the rear side of the supporting frame correspondingly; and the problems are solved that most existing hardness detection devices for the high-strength steel bars are exposed in the detection process and then hardness detection is carried out, so that in the detection process, safety is low, breakage can be caused, fragments of the existing hardness detection devices splash under the action of pressure, an operator is easily injured, and potential safety hazards exist.

Description

technical field [0001] The invention relates to the technical field of building material detection, in particular to a hardness detection device and a detection method for high-strength steel bars. Background technique [0002] High-strength steel bar refers to the steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners, including smooth round steel bar, ribbed steel bar, and twisted steel bar. [0003] In the process of building construction, high-strength steel bars need to be used in many places to play a supporting role. High-strength steel bars need to be tested for hardness to ensure the yield and service life of high-strength steel bars. The existing hardness testing devices for high-strength steel bars are in During the testing process, most of them are exposed and then tested for hardness, which will lead to low safety during the testing process and cause breakage. Hidden danger. ...
