Description

Technical Field

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

[0002] Steel structure refers to building materials made of steel or steel alloy as the main materials. It is widely used in factory construction, large equipment preparation and other fields. After the steel structure is completed, stress detection equipment is usually used to test its compressive stress and other tests to determine whether the steel structure meets the production standards.

[0003] The existing patent (publication number: CN115655895A) is a stress detection device for building steel structures, including a base plate and a steel structure. Two moving columns are installed on the base plate through two moving mechanisms. Positioning boxes are fixedly installed on the two moving columns, and positioning mechanisms are installed in the two positioning boxes, and the steel structure is placed between the two positioning boxes. A top rod is fixedly installed on the base plate through two side rods, a sliding sleeve is provided on the top rod, and a lifting rod is installed on the sliding sleeve through a sliding mechanism, an extrusion piece is fixedly installed on the lifting rod through a pressure detector, a center column and a traction motor are fixedly installed on the base plate, and a winding roller is fixedly installed on the driving end of the traction motor.

[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art that have not been solved: the patent can not only perform multi-point compressive stress detection on steel structural parts with higher detection accuracy, but also perform bending stress detection on steel structural parts, with more comprehensive detection, wider detection range and stronger functionality. However, there is no protective mechanism at the contact point between the existing extrusion parts and the steel structure. When the steel structure is extruded, it is easy to break and cause debris splashing, which can easily cause harm to personnel. Moreover, the generated debris will fall on the processing table, which requires personnel to manually clean it up, which is more troublesome. Therefore, we propose a stress detection device for building steel structures. Utility Model Content
