[0002] Building engineering detection mainly includes the detection of the physical and mechanical properties of materials entering the construction site, analyzing data to obtain the material mix ratio of building engineering design, and detecting the construction quality to ensure compliance with design and specification requirements. The steel bar pulling test is the on-site detection of the anchoring force of the anchor solid. Generally, after the steel bars are implanted for 48-72 hours, the implanted steel bars are subjected to the pulling test. During the process of engineering construction, a large amount of reinforced concrete is required. In order to detect whether the anti-pulling bearing capacity of the steel bars meets the construction standards, it is necessary to conduct a pulling test on the steel bars.
