How to hoist steel plate in steel structure construction?The following is a brief introduction:
1.By using the method of adding floors to the steel structure workshop, not only can the utilization area of the building be expanded, but also the opposition of the lack of housing at that time can be alleviated.
2.After adjustment and planning, we can make the house look new and improve the appearance of the city.
3.The original foundation and data can be used to reduce the cost of the project.
4.The use of steel structure to add floors can achieve the purpose of saving land, supply land utilization rate, and reduce the cost of household moving and settling together.
5.Reduce site excavation, construction data stacking, transportation and processing.
6.By adding ring beams, structural columns, internal and external columns and other reinforcement methods, the seismic capacity and stress condition of the building are improved, and the service life of the building is extended.
7.If the original building is reconstructed by adding floors, the operation of the original building will not be suspended (only part of the application will be suspended), and the production, education and operation will not be delayed.
8.It can make full use of the growth value of the bearing capacity of the foundation under the long-term load effect of the existing buildings, as well as the safe storage of the foundation in the planning of the existing buildings, or the favorable conditions for the improvement of the bearing capacity of the foundation caused by the decline of the groundwater level, it is most economical to directly carry out the steel structure storey adding reconstruction project without foundation treatment or slight treatment.
Process 1: the ground operators locate the hoisting operation
The operation content and safety items are: recognize the standard and scale of steel bearing plate and its hoisting position.
Process 2: check the hoisting equipment
The operation contents and safety items are as follows:
(1) There should be anti-skid tongue on the hook and spreader.
(2) The steel cable and retaining ring should have enough strength, and the steel structure in Shanghai should not crack or deform.
Process 3: preparation before lifting
The operation contents and safety items are as follows:
(1) Firstly, the lifting position of steel bearing plate should be planned to bear the lifting load.
(2) Before lifting, the control rope should be placed in the proper position of the buckle ring, so that the steel bearing plate is convenient for hoisting and stacking.
(3) There should be corresponding isolation methods, and no personnel are allowed to enter during lifting.
Process 4: the hook is hung on the steel cable and buckle ring, and the operation contents and safety matters are as follows: the steel structure admits that all parts are tightly connected, and then the steel cable is hung on the hook.
Lifting process of crane
The operation content and safety matters are: lifting according to the command signal.
Step 6: after the steel bearing plate is hoisted to its position, the stacking position of the steel bearing plate shall be carried out
The operation contents and safety items are as follows: the operators shall inspect the appliances and tools, and the steel structure shall wear the safety protection measures.
Process 7: release the hanging steel lock and position the steel bearing plate
The operation contents and safety items are as follows: the steel cable, buckle ring and spanner should be avoided from flying down, and the planned orientation should be acknowledged.
