Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering detection, and more specifically, to a steel strength detection device. Background Art

[0002] The strength of construction steel refers to the ability of the material to resist fracture under the action of external forces. The strength of construction steel is an important criterion that must be measured during the use of the material. These steels usually have to pass the mechanical property test before they can be used. The strength test of steel is mainly carried out from the aspects of the tensile strength and bending strength of the steel, which requires the use of steel strength testing equipment.

[0003] At present, most of the steel strength testing devices on the market for bending strength are troublesome to use on construction sites in actual production life. Because steel has different shapes and often has sharp edges, most testing devices have pressure sensors. The sensors are in direct contact with the steel at the force application point, and excessive contact can easily damage the sensors.

[0004] After searching, the Chinese patent with publication number CN218823643U discloses a steel strength testing device. The steel strength testing device is small in size and has a handle on the L-shaped support structure, which makes the steel strength testing device compact and portable, and convenient for use at the construction site. The presence of the connecting component prevents the pressure sensor from directly contacting the force application point of the steel, making the sensor less likely to be damaged. At the same time, the rectangular hole on the base limits the L-shaped pressure plate, so that the L-shaped pressure plate will not slide during the process of fixing the steel, thereby ensuring that the steel will not move during the detection process.

[0005] When the above-mentioned steel strength testing equipment is actually used, the traditional fixing method may cause the steel to shake during testing, resulting in errors in the measured data and a decrease in the accuracy of the test results. At the same time, the staff is required to readjust and re-fix, which increases the complexity of the operation. Utility Model Content
