Reinforcement construction plan for steel structure industrial plant
As the country vigorously develops clean energy, photovoltaic systems are widely used in the field of industrial buildings. Steel structure workshops have been widely used due to their high strength, fast construction, and recyclability. However, with the passage of time, changes in usage functions, or natural disasters, some Steel structure workshops may experience a decline in structural performance. At this time, steel structure reinforcement is particularly important, and a scientific and reasonable steel structure construction plan is the key to ensuring the quality and safety of the reinforcement project.
First of all, before the reinforcement construction of the steel structure workshop, it is necessary to conduct a comprehensive and detailed inspection and evaluation of the workshop structure. According to the relevant steel structure design specifications, check whether there are defects such as rust, deformation, and cracks in the beam-column nodes, rod connections, and foundations of the workshop. Through professional testing equipment and technical means, such as ultrasonic flaw detection to detect internal defects in steel, total station measurement of structural deformation, etc., accurate data information is collected to provide a basis for the subsequent formulation of targeted reinforcement plans.
There are many common steel structure reinforcement methods, among which the cross-section reinforcement method is more commonly used. For components such as steel beams and steel columns, additional steel plates, angle steels and other materials are welded or pasted on their surfaces to increase the cross-sectional area of the components, thereby improving their bearing capacity. During the construction process, operations must be carried out strictly in accordance with the requirements of the steel structure construction process. For example, the steel surface needs to be rusted and cleaned before welding to ensure the welding quality. When welding, select appropriate welding process parameters, such as welding current, voltage, welding speed, etc., to ensure that the weld is full and free of defects such as pores and slag inclusions. In addition, attention should be paid to the integrity of the connection between the newly added section and the original structure. Reasonable connection methods, such as groove welding and high-strength bolt connection, can be used to make the reinforced components work together.
Another effective reinforcement method is external prestressed reinforcement. For bending components such as beams and trusses of large-span steel structure workshops, prestressed steel cables or pull rods are applied to the outside of the components to generate reverse bending moments on the structure to offset part of the internal forces generated by the original load and improve the stiffness and bearing capacity of the structure. During construction, the prestressed anchor device is first installed at a suitable position of the workshop structure, and then the prestressed steel cables or pull rods are tensioned. The tensioning process needs to strictly control the tensioning force and tensioning sequence. Professional equipment such as jacks can be used for graded tensioning, and the deformation of the structure can be monitored in real time to prevent structural damage due to improper tensioning.
In addition, there is also a reinforcement method of pasting carbon fiber composite materials. Carbon fiber cloth or carbon fiber plate is pasted on the surface of the steel structure with a special adhesive, and the high strength characteristics of carbon fiber materials are used to enhance the bearing capacity of the structure. During construction, the surface of the steel structure needs to be polished to make its roughness meet the requirements to ensure the bonding effect of the adhesive. During the pasting process, it is necessary to ensure that the carbon fiber material fits tightly with the surface of the steel structure without bubbles or hollows. Rolling, vibrating and other methods can be used to fully infiltrate the carbon fiber material and the surface of the steel structure.
Safety management is crucial during the entire steel structure plant reinforcement construction process. Obvious safety warning signs should be set up at the construction site, and safety education and training should be conducted for construction personnel to familiarize them with the safe operating procedures for steel structure construction. When working at heights, protective facilities such as safety belts and safety nets must be equipped to prevent accidents of personnel falling. At the same time, the construction sequence and progress should be arranged reasonably to avoid safety hazards caused by cross-operation. The reinforcement construction of steel structure workshops is a complex and systematic project, which requires comprehensive consideration of the structural characteristics, use requirements, economic costs and other factors of the workshops. Only by selecting appropriate reinforcement methods, strictly following the steel structure construction specifications, and strengthening safety management can we ensure that the reinforced steel structure workshops are stable, safe and reliable, continue to play an important role in industrial production, extend their service life, and create greater economic benefits for enterprises.
