Background Art

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 and steel plates. The components or parts are usually connected by welds, bolts or rivets. In the production of steel structures, it is necessary to conduct sampling inspections on steel structures and pressure tests on the same batch of steel structures to ensure the quality and safety of steel structures.

For example, a document with prior art publication number CN214309947U provides a steel structure strength detection device, which includes a fixed base, a fixed frame fixedly connected to the surface of the fixed base, a detection cylinder is arranged on the top of the fixed frame, a detection plate is arranged on the top of the inner cavity of the fixed frame, the movable end of the detection cylinder passes through the fixed frame and is connected to the detection plate, etc. The device clamps the steel structure by a clamp and applies pressure to the steel structure by the detection cylinder, thereby detecting the strength of the steel structure.

Although the device has many beneficial effects, it still has the following problems: the fixed frame used to install the detection cylinder is fixed, that is, when the steel structure is subjected to pressure testing, the position where the detection cylinder applies pressure to the steel structure cannot be changed and adjusted, which is not convenient for testing the relationship between the distance of the steel structure from the clamping point and the strength. In view of this, we propose a steel structure strength testing device.
