When we use steel structure products to work, we will carry out a hoisting operation for high-rise and multi-layer structures. This hoisting operation is very important. It is helpful to remove the accumulation of installation errors and the welding deformation of joints, so that the errors can be reduced to a very small limit, and it is related to the installation of the structure. It's going on normally. No one can guarantee 100% that there will be no problems in the hoisting construction. Therefore, we must make relevant preparations when hoisting, and pay more attention to the occurrence of safety accidents. So, what preparatory work should be done for the hoisting of this structure?
I. The following basic conditions should be met before hoisting:
1. The reinforced concrete foundation is completed and qualified for acceptance.
2. The compilation and auditing of the special construction schemes have been completed.
3. Construction temporary water and electricity laying in place, the plan has been completed according to the plan.
4. Installation, commissioning and acceptance of construction tools are qualified.
5. Access and acceptance of components.
6. Labor force enters the market.
II. Precautions before hoisting of steel structures:
1. Technical and safety submissions should be made to all construction workers before hoisting.
2. Strictly follow the hoisting steps of the handover.
3. Strictly abide by the lifting, welding and other operating procedures, in accordance with the content of process assessment, problems in accordance with the content of the submission.
4. Strictly abide by the operating rules and prohibit the operation or construction under harsh weather conditions.
Operators must know more about these things, which is especially important for safety. Once an accident or problem is discovered, the operator should stop the hoisting work immediately, check the equipment structure, find out the cause of the problem, and solve it immediately. These preparations can be solved at the first time when problems arise, which is conducive to the normal operation of the work.
