Description

Technical Field

[0001] The utility model belongs to the technical field of steel material testing equipment, and specifically relates to a steel material strength testing device, which is mainly used for testing the strength of steel materials with larger specifications used in bridge construction. Background Art

[0002] Steel materials are usually tested for their mechanical properties before use, and the strength of steel materials is an important indicator that must be tested. A large number of large-sized steel materials are often used in bridge construction. These steel materials need to be tested for strength before use and installation to ensure that the steel materials will not break during use. The strength test of steel materials is generally carried out using steel strength testing devices.

[0003] The Chinese patent with publication number CN220339908U discloses a steel strength detection device, which includes a detection body, an indicator light and a control panel are arranged on the side end of the detection body, a detection slot is arranged on the side adjacent to the control panel, and detection ports are distributed on the table of the detection body and other technical contents. The steel strength detection device adopts the form of multi-port synchronous detection in combination with a signal sensing method to achieve overall detection and accurate detection effects. After the steel is embedded, pressure is applied to different positions of the steel through multiple groups of pressure ends. While ensuring that the steel is pressed tightly, strength detection is also achieved. After pressure is applied, the steel is greatly deformed and contacts the pressure sensor at the corresponding position, which proves that the corresponding position of the steel is unqualified and is accompanied by a corresponding indicator light prompt. According to the strength detection of different positions of the steel, the overall qualified rate of the steel can be determined, and the technical effects such as comprehensive detection and accurate determination can be achieved.

[0004] Although the design of the above patent can determine the overall pass rate of steel, the test is comprehensive and the judgment is accurate, but in actual use this design can only perform strength tests on some slender steels, and cannot perform strength tests on larger-sized steel sections used in bridge construction. The structural form of the steel embedding port it adopts cannot adapt to steel sections of different specifications and models, and it also lacks reliable fixation for the steel to be inspected.

[0005] In order to solve the above problems, a new steel strength detection device is proposed in the present application. Utility Model Content
