Study on Construction Safety Index and Weight Grade of Disc-buckled Full Support
In order to avoid the occurrence of safety accidents and casualties in the whole process of the construction of the disc-buckled full support,the safety indexes and their weight grades involved in the construction process of the disc-buckled steel pipe support(Abbreviated as disc-buckled bracket are clarified.66 construction safety accidents of full support and 12 relevant standards were investigated,and the importance of safety indexes of disc-buckled support considering the influence of expert confidence index was investigated and analyzed.The research shows that a total of 77 construction safety indexes of disc-buckle support were screened out,and the hierarchical structure of construction safety indexes of disc-buckle support was constructed based on the analytic hierarchy process.After the weight classification,a total of 34,20 and 23 grade Ⅰ,Ⅱ and Ⅲ safety indexes were extracted,which can provide a theoretical basis for the construction safety management of disc-buckle full support and prevent safety accidents in the construction process to a certain extent.
