Technical Field

[0002] A skeleton-structured building is a building that uses a structural system composed of members to bear the loads transmitted from the roof and floor. The components of the skeleton structure have clear divisions of labor, and materials can be selected according to needs. For example, the load-bearing skeleton can be made of steel or reinforced concrete with good mechanical properties, and the non-load-bearing walls can be made of lightweight materials with good sound insulation and heat insulation.

[0003] In current life, building steel bars refer to various steel bars, steel wires, etc. used in reinforced concrete. When using building steel bars, according to the actual situation, it is necessary to bend the building steel bars, and after bending, it is necessary to detect the bending angles of these building steel bars to determine whether their bending angles are qualified.

[0004] After retrieval, a Chinese utility model patent with the authorization announcement number of CN214373979U discloses a steel bar bending fatigue detection device. Its structure includes a detection table, on which there are opposite fixed seats and fixed frames. A locking frame is fixedly installed on the fixed seat. The locking frame and the fixed frame are respectively used to fix the two ends of the steel bar to be tested, and a mechanical sensor for detecting the force condition of the steel bar is arranged in the fixed frame; a displacement mechanism is arranged in the detection table, and the displacement mechanism passes through the detection table and is fixedly connected to the fixed seat above the detection table. The displacement mechanism can drive the fixed seat to move, and then the fixed seat can drive one end of the steel bar to bend through the locking frame. The mechanical sensor located at the other end of the steel bar can detect the bending fatigue of the steel bar. This utility model realizes the function of driving the transmission rod to make the connecting rod uniformly stressed and reciprocate left and right by rotating the rocker; both ends of the connecting rod are fixedly connected to the side axles of two gears through rotating shafts, which plays the role of driving the two gears to reciprocate left and right on the top surface of the fixed rack; the two gears can drive the moving rack to move along the slide rail, and then drive the fixed seat on the moving rack to move. The locking frame connected to the fixed seat and the fixed frame opposite to the locking frame respectively fix the two ends of the steel bar, and the locking frame drives one end of the steel bar to move under the action of the fixed seat, realizing the bending of the steel bar.

[0005] In the process of implementing this application, at least the following problems exist in this technology. The steel bar angle detection device for this building steel bar bending equipment detects the anti-bending ability of a certain type of steel bar at a fixed distance, which is inconvenient for multi-section distance detection, resulting in the inability to know the standard of the force that the steel bar can withstand at each distance, and it is also inconvenient to detect steel bars of different lengths, making the detection efficiency limited.
