Abstract
The invention discloses a method for a mechanical property test of a scaffold in the safe state. The method comprises steps as follows: (1) a test model is set up, gasket type pressure sensors are placed at bolts of fasteners, and a static strain test acquisition instrument is externally connected; (2) the tightening torque is adjusted by the aid of a torque wrench, the pressure is exerted step bystep by the aid of a press in the range of a load p, and data conditions are observed and acquired; (3) unlading is performed, the tightening torque at each fastener is adjusted into other torque, and the test is repeated. According to the method, the tightening torque is adjusted, the pressure is exerted step by step by the aid of the press, and the gasket type pressure sensors are placed at thebolts of the fasteners to acquire pressure information, so that the test result of the mechanical property of the scaffold in the safe state is obtained, and the safety property of the scaffold in aconstruction project is guided.
Description
technical field [0001] The invention relates to the technical field of scaffolding mechanical performance testing, in particular to a method for testing the mechanical performance of scaffolding in a safe state. Background technique [0002] At present, with the rapid development of the national economy, with the development and expansion of the construction industry and the scale of infrastructure construction, the construction safety of scaffolding has also become the focus of attention. In recent years, the collapse accidents of fastener-type steel pipe scaffolding in my country have shown an obvious upward trend. [0003] In view of this situation, it is necessary to carry out mechanical experiments on fastener-type scaffolding docking fasteners or right-angle fasteners in a safe state. Using the existing steel pipe scaffolding material characteristics and technical requirements for erection, combined with the experimental conditions of the laboratory, The material prop...
