In the renovation project of the old factory building, retaining and using the original structure is an important way to achieve resource conservation and sustainable development.The prefabricated industrial plant structure can continue to be used after proper reinforcement within the design service life.Before reinforcement, the original structure needs to be comprehensively tested and appraised to understand the status quo of the structure and the remaining carrying capacity.The inspection content includes component size, material strength, connection condition, degree of corrosion, etc.According to the test results and the requirements for use after the transformation, determine the scope and plan of reinforcement.

There are many options for structural reinforcement technology, which need to be determined according to specific circumstances.For components with insufficient carrying capacity, the method of increasing the cross-section can be used to increase the cross-section or reinforcement of the components.For connecting weak nodes, additional connecting plates and bolts can be used to strengthen them.For structures with insufficient overall stiffness, a support system or shear wall can be added to improve the side resistance.For rust-damaged components, rust removal treatment is required first, and then reinforcement and reinforcement are carried out.The reinforcement material should be compatible with the original structure, and the reinforcement construction should minimize damage to the original structure.

Safety control during construction is an important part of the reinforcement project.During the reinforcement construction, the original structure may be in a state of stress, and temporary support and other measures need to be taken to ensure the safety of the construction.The connection between the new components and the original structure needs to be reliable, and the force transmission path needs to be clear.After the reinforcement is completed, a load test or structural inspection is required to verify the reinforcement effect.After being put into use, regular monitoring is required to observe structural deformation and cracks to ensure safety.These technical measures and management requirements have made it a feasible and economical solution to retain the original prefabricated industrial plant structure for transformation, continuing the life cycle of traditional industrial buildings.
