For this reason, safety nets made of steel (e.g., punched steel plate nets) have been used. At present, the connection modes between the steel plate meshes and the attached lifting scaffold body mainly comprise iron wire binding connection, half-side buckling connection, bolt direct connection and the like. The common characteristics of the different connection modes are that an integral rigid structure body is arranged between the connection mode and the scaffold and between the connection mode and the safety net, when the scaffold is strongly impacted by external forces such as falling objects, storms and the like, stress concentration of a stressed part has no buffer room, the safety coefficient is low, and potential safety hazards exist; once the constructors fall down on the steel plate net carelessly, the constructors can be damaged seriously due to lack of buffering. Therefore, a plurality of major accidents of collapse of the attached lifting scaffold still occur at present, and serious loss of constructors and property is caused. Therefore, the safety and reliability in the construction of the safety protection system of the attached lifting scaffold are further ensured and improved, and the practical problem which is not overlooked and needs to be solved urgently is solved.
