The formwork support system controls the safety from materials, design, construction and strength.
Material control: all fasteners must be sampled and tested according to the regulations, and can be put into use only after they are qualified. They shall be strictly managed according to relevant regulations, and fake and unqualified fasteners shall be strictly prevented from entering the site and being used. The steel pipe must be strictly inspected before use, and spot check test shall be carried out according to the regulations. The steel pipe can be put into use only after it is qualified.
Design control: the fastener type steel pipe formwork support system must have design calculation and erection scheme - strength, stiffness and stability of the upright, anti sliding force of the fastener, strength and deflection checking calculation of the horizontal bar, foundation bearing capacity of the upright or floor bearing capacity of the supporting upright.
Construction management: technical management and safety management. The formwork support system shall be designed before construction. The operation shall be carried out in strict accordance with the technical scheme of formwork design, and no random change is allowed.
Strength control: when the formwork is removed, the concrete strength must meet the requirements of the Code for Construction and Acceptance of Concrete Structures.
In a word, the safety control should: check the design calculation of the support system and the construction drawing of the support erection, and the approval procedures should be complete; The responsibility is assigned to each person, and the disclosure procedures are complete; Formwork support materials must be strictly controlled; Supervision and inspection shall be strengthened during erection; High formwork support shall be highly valued; Establish the acceptance system of formwork support system; The observation shall be strengthened during the use of formwork support; The load on the support shall be controlled; The removal of formwork support system shall be reported for approval.
