There are numerous precautions to consider during the installation of steel structure coal sheds. Below is an introduction covering aspects such as construction preparation, component installation, welding and connections, roof and wall installation, and safety management.

Construction Preparation

Site Clearing: Ensure the construction site is level and free of debris, providing suitable working conditions. In particular, remove any obstacles that may hinder the installation of steel structures to facilitate the transportation and storage of construction equipment and materials.

Material Inspection: Verify the model, specifications, and quantity of steel structure components. Check for any deformation, damage, or coating peeling on the components. Additionally, ensure the quality of connecting materials (such as bolts, welding rods, etc.) meets requirements.

Construction Equipment Preparation: Based on the construction plan, prepare all necessary equipment, such as cranes, welding machines, gas cutting tools, and measuring instruments. Ensure the equipment is in good working condition and operates properly.

Component Installation

Foundation Inspection: Before installing steel structure components, inspect the foundation to verify that its axis, elevation, and flatness comply with design requirements. Ensure the foundation's anchor bolts are correctly positioned, sized, and extend to the proper length.

Component Lifting: Use appropriate lifting methods and rigging to prevent deformation or damage during hoisting. Select lifting points based on the component's shape, size, and center of gravity to ensure stable lifting. During installation, conduct timely measurements and adjustments to guarantee accurate positioning.

Component Connection: The primary connection methods for steel structures include welding and bolting. Strictly adhere to design requirements and construction standards during the connection process. For bolted connections, ensure the tightening torque meets specifications to prevent loosening.

Welding and Connections

Welding Process: Welding is a critical procedure in steel structure construction, as its quality directly impacts safety. Select suitable welding techniques and materials based on the component's material and thickness. Welding must be performed by qualified welders.

Weld Inspection: After welding, conduct visual inspections and non-destructive testing to check for defects such as pores, slag inclusions, or cracks. Address any issues promptly with repairs.

Roof and Wall Installation

Roof Installation: The roof system should be installed after the main steel structure is in place. When installing color steel roofing panels, pay attention to the laying direction, overlap length, and sealing to prevent leaks. Additionally, ensure the spacing of roof purlins meets design requirements to maintain flatness and stability.

Wall Installation: Color steel wall panels must be installed with proper vertical and horizontal alignment, ensuring tight connections between panels. When creating openings for doors and windows, ensure accurate dimensions and positioning, and reinforce and seal the openings to prevent water infiltration.

Safety Management

Personnel Safety: All construction personnel must wear personal protective equipment such as hard hats and safety harnesses. For high-altitude work, install reliable safety measures like safety nets and guardrails.

Equipment Safety: Regularly inspect and maintain construction equipment to ensure safe operation. Strictly follow operating procedures to prevent accidents caused by equipment failure or improper use.

On-Site Safety: Keep the construction site clean and organized. Store materials and equipment safely to prevent collapses, fires, or other hazards. Clearly mark safety warning signs and restrict access to unauthorized personnel.
