Reinforcement Of Buildings After Fires
Carbon Fiber Plate
After a fire occurs, it will definitely have a certain impact on engineering structures, reducing their bearing capacity, increasing their deformation, and reducing their service life. The magnitude of the impact is closely related to the size, severity, and form of the engineering structure of the fire.
Project reason: Reinforcement of concrete components after fire
Project Material: Carbon fiber plate
After a fire occurs, it will definitely have a certain impact on engineering structures, reducing their bearing capacity, increasing their deformation, and reducing their service life. The magnitude of the impact is closely related to the size, severity, and form of the engineering structure of the fire.
The degree of damage to the project after a fire should be evaluated by a qualified housing inspection and appraisal company.
There are three types of housing appraisal results:
The first scenario is that the damage is severe and the overall structure has problems, which cannot guarantee the safety of the structure in the future. Therefore, it is necessary to demolish and rebuild the structure.
The second situation is relatively minor and requires maintenance and reinforcement before continuing to use.
The third type is relatively mild and does not require reinforcement.
How to reinforce the building structure after a fire
1. Basic principle: The repair and reinforcement design should be simple, feasible, safe, reliable, and economically reasonable; Pay attention to the node structure and construction method of the reinforced components, ensure that the reinforced part works together with the original structure, and consider the impact of reinforcement on the overall stress changes of the building.
2. To ensure construction quality, due to the differences in the structure and construction methods of repair and reinforcement compared to normal construction, it is necessary to emphasize meticulous construction to ensure quality.
3. Reinforcement methods for reinforced concrete structures after fire
The reinforcement method of pasting carbon fiber cloth (plate): refers to the reinforcement method of pasting carbon fiber cloth (plate) onto the surface of a reinforced concrete structure through a matching adhesive, so that the two form a unified whole and bear the force together, thereby improving the structural bearing capacity.
