Description

Technical Field

[0001] This utility model relates to the technical field of steel bar detection and protection, specifically a steel bar strength tester. Background Technology

[0002] Reinforcing bars refer to steel used in reinforced concrete and prestressed reinforced concrete, with a circular cross-section, sometimes square with rounded corners. They include plain round bars, ribbed bars, and twisted bars. Reinforcing bars for reinforced concrete refer to straight or coiled steel bars used for reinforcing concrete, and their shape is divided into plain round bars and deformed bars, delivered in straight bars or coils.

[0003] Chinese patent application number 202221017529.0 describes a rebar strength tester, including a workbench with a groove at the bottom. A weighing device and a digital display device are installed inside the groove. A hydraulic rod is installed at the top of the inner wall of the workbench. Two baffles are fixed to the inner wall of the workbench, and cylinders are fixed to the opposite ends of the two baffles. The outer ends of the shafts of the two cylinders are slidably connected to the baffles. In this invention, the two cylinders drive two first clamping blocks to move in opposite directions, thereby moving the two side plates in opposite directions to clamp and limit the rebar, preventing displacement and tilting of the rebar when the hydraulic rod is driven and compressed. The pressure of the hydraulic rod is displayed on the digital display device to detect the strength of the rebar. The side plates, sleeve rod, sliding rod, and spring act as a buffer to limit the rebar, making the device suitable for use with rebars of different sizes and more convenient to use. This technical solution achieves strength detection by compressing the end face of the rebar and using a pressure sensor. However, there is a safety hazard of the rebar breaking off and ejecting, causing injury, when compressing the end face of the rebar. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments.
