Prefabricated steel frame warehouse is a new force. Improve the design specifications and construction technical standards of different types of steel structures, develop new steel materials comparable to traditional technologies, and learn from mature advanced experience. Only in this way can it speed up its industrialization process, meet the needs of the market, and promote the development of steel frame warehouse.
For the high-altitude connection between columns and beams, and between beams and beams, a stable and reliable temporary working platform should be set up, and a ladder should be set up for each column to facilitate construction personnel to go up and down and operate.
When installing horizontal components such as crane beams, inter-column supports, pipe racks, and roof beams, safety ropes should be installed first (the diameter of the rope should not be less than 6mm, and 8mm galvanized steel wire ropes are generally used), so that it is convenient for construction workers to hang them safely when moving in the air. bring.
The installation and welding of the diagonal braces of the roof beams, the installation and welding of the diagonal braces between the columns need to use the hanging cage, and the manufacturing of the hanging cage should not use rebar to avoid brittle fracture.
During construction, structural platforms, passages, stairs, holes, and roof edges should be maintained, and safety measures should be taken as far as possible, and safety protection measures should be taken.
The hoisting operation requires a special person to command, fixed posts and designated personnel cooperate with the unified organization of the hoisting operation, and unauthorized overload hoisting and multi-headed command operations are strictly prohibited.
The slings should be inspected before the hoisting operation, and the slings that are damaged or do not meet the safety requirements shall not be used without repair.
Structural parts must be tied firmly for transportation and unloading, stacked steadily and firmly, anti-deformation, anti-collapse and dumping, no hook loosening if not fixed, and sheaths must be added at the edges and corners of the sling.
Follow the relevant procedures for installation work. The lifting operation implements the “ten no lifting” regulations, and the safety belt is used for high-altitude and low-hanging safety belts.
Operators must strictly abide by the operating procedures of each post, and especially make corresponding signs, signals and warnings for dangerous sources, so as to avoid injury to others.
All types of work must strictly abide by the safety technical operating procedures, and conduct safety studies and education for all types of personnel in accordance with relevant labor laws and regulations, especially for special types of work that must hold a certificate.
Strengthen fire management and control, and strictly implement the fire approval system and fire supervisor system.
Strictly abide by the regulations on fire prevention at the construction site, strengthen fire protection publicity and education, add fire protection facilities and equipment, and conduct regular inspections to eliminate hidden dangers. Enhance fire awareness and prevent fire accidents.
With the continuous improvement of science and technology, the living standard is increasing, the demand is increasing, and the development of the construction industry is striving for perfection. Steel structure is an important and necessary material, especially in the application of prefabricated warehouse. Combined with the performance of steel structure, the hoisting process and quality assurance should be well grasped, so that it can face the development prospects of the world.
