Background:

The old factory building of a company was built in the 1970s and has been in use for over 30 years. Due to long-term use and natural aging, some parts of the old factory building have problems such as cracks and deformation, which pose certain safety risks. In order to ensure the safety and stability of the factory building, the company decided to reinforce the old factory building and use carbon fiber reinforcement technology for reinforcement.

Design analysis

Column reinforcement: Reinforce the columns of the old factory building using carbon fiber reinforcement technology. The specific plan is as follows:

Clean and treat the surface of the column to ensure it is smooth, clean, and free of oil and loose materials.

Cut the pre-prepared carbon fiber cloth to the required length and width.

Apply epoxy resin to the carbon fiber cloth and paste it on the surface of the column, ensuring full adhesion and coverage.

Use a brush or roller to compact the epoxy resin on the surface of the carbon fiber cloth, ensuring full infiltration and solidification.

Beam reinforcement: Reinforce the beams of the old factory building using carbon fiber reinforcement technology. The specific plan is as follows:

Clean and treat the surface of the beam to ensure it is smooth, clean, and free of oil and loose materials.

Cut the pre-prepared carbon fiber cloth to the required length and width.

Apply epoxy resin to the carbon fiber cloth and paste it on the upper and lower surfaces of the beam, ensuring full adhesion and coverage.

Use a brush or roller to compact the epoxy resin on the surface of the carbon fiber cloth, ensuring full infiltration and solidification.

Wall reinforcement: Reinforce the walls of the old factory building using carbon fiber reinforcement technology. The specific plan is as follows:

Clean and treat the surface of the wall to ensure it is smooth, clean, and free of oil and loose materials.

Cut the pre-prepared carbon fiber cloth to the required length and width.

Apply epoxy resin to the carbon fiber cloth and paste it on the surface of the wall, ensuring full adhesion and coverage.

Use a brush or roller to compact the epoxy resin on the surface of the carbon fiber cloth, ensuring full infiltration and solidification.

Solutions

Before construction, a comprehensive inspection and evaluation of the old factory building should be carried out to determine the parts that need to be reinforced and the reinforcement plan, and a detailed construction plan and safety measures should be formulated.

During construction, the reinforcement plan should be followed to ensure the quality and bonding effect of the carbon fiber cloth and epoxy resin.

Safety measures should be taken during construction, such as wearing safety helmets, gloves, and protective goggles.

After construction is completed, a comprehensive inspection and testing should be carried out to ensure that the reinforcement effect meets the design requirements, and any problems discovered should be dealt with promptly.

By adopting carbon fiber reinforcement technology, the structural reinforcement of the old factory building of a company has been effectively carried out, which effectively solves the safety risks and stability problems that existed before. The advantages of using carbon fiber reinforcement technology include easy construction, significant effect, and no impact on the original structure's aesthetics. In the actual construction process, the quality of construction and safety management should be strengthened to ensure the reinforcement effect and construction safety.
