Recently a piece of sad news spread on the Internet. Beilong Hot Spring Leisure Hotel in Sun Island Scenic Area, Songbei District, Harbin, a fire broke out on the night of August 25th, killing 20 people, injuring 23 people and causing huge house damage and property damage. Personal damage can be healed through compensation and the passage of time. Then how can the damage of the house in the fire be reinforced with carbon fiber cloth?
The house after the fire generally has a relatively large injury. First, it is necessary to judge the status of the house. If it is indeed more serious damaged, reconstruction is a better choice. If it is not very serious, it can be judged separately for the overfire area to carry out the reinforcement of the targeted carbon fiber cloth.
If the beam is burnt, especially the slab beam is always burnt on the lower side, that is, the fire damage is mainly in the tension zone. Since the concrete layer is peeled off, the steel bars are often exposed, and the necessary additional steel bars should be added during reinforcement. After removing the loosened concrete layer, the additional ribs are placed on the beam to ensure good anchoring of the additional steel bars; then the carbon fiber cloth impregnated adhesive is used to bond the carbon fiber cloth to the bottom of the structural beam (bottom) or side (board). Through the glue bonding, the carbon fiber cloth and the original structure bear the structural load together, thereby achieving the purpose of reinforcing and bearing.
If the column is burnt, the carbon fiber impregnated adhesive should be used to wrap the carbon fiber cloth around the structural column to prevent the structural column from being laterally damaged, thereby ensuring the safety of the column.
Regardless of the location of the carbon fiber cloth reinforcement, the principle of safety first must be followed. If you don't know which reinforcement way to use, you can consult Nanjing Mankate with 15 years of experience in carbon fiber production. We will provide you with nuanced service.
