Analysis on the causes and prevention measures of the potential safety hazard of the formwork support system

In recent years, with the rapid development of urban modernization, the collapse of formwork support system occurs frequently. The erection of formwork support system has become the key control object in the current construction safety production. This paper summarizes the main reasons for the potential safety hazards of the formwork support system in four aspects. The design of formwork support scheme is lack of guidance; the material and specification of formwork support system do not meet the standard; the formwork erection personnel are not professional; the management concept of the general contractor and subcontractor is different, and the supervision implementation is not complete. In view of the above reasons for the potential safety hazards, this paper innovatively puts forward the use of three-dimensional virtualization technology to make the virtual positioning of the mold support system, increase the mold support system process (three-dimensional positioning, solid line inspection); the frame rental is suggested to be self-sufficient, customized frame materials to establish the internal material catalogue for the use of turnover; sets up a new type of work, carry out assessment and training according to the scaffolders, and understand woodworking skills, so as to promote the standard erection of formwork support system; changes the conventional quota calculation rules, and increases the lower limit usage amount (tonnage calculation) of support system materials per square meter in the subcontract management agreement, so as to limit the abuse of excessive cost control.
