Description

Technical Field

[0001] The utility model relates to the technical field of steel structure stress detection equipment, in particular to a building steel structure stress detection equipment. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. In order to ensure the construction quality of steel buildings, stress testing of steel is often required before construction to ensure that the steel meets the construction requirements.

[0003] Existing stress detection equipment for building steel structures can often only perform stress detection on one type of steel, and is only suitable for detecting and fixing one type of steel, and cannot detect and fix steels of multiple different specifications, which makes the applicability of the equipment low. Therefore, there is a problem that it cannot detect and fix steels of multiple different specifications. In addition, the existing stress detection equipment for building steel structures only measures the compressive stress of steel, and cannot measure the torsional stress of steel, which reduces the practicality of the equipment. Therefore, there is a problem that it cannot measure the torsional stress of steel. In summary, the utility model has the problem that it cannot detect and fix steels of multiple different specifications and cannot measure the torsional stress of steel. Utility Model Content
