Many old-fashioned communities have been in disrepair for years, and the floors are prone to have cracks or slabs sinking. Especially in some communities built in the early 1990s, the concrete used is insufficient in strength and lacks durability, which is prone to appear instability. Therefore, if the old-fashioned communities appear cracks or sinking of the floor, it is necessary to take the method of carbon fiber reinforcement at the top of the board for maintenance. Why is the old-fashioned community not suitable for reinforcement with planting bars or steel? Please listen to our explanation.
First of all, the concrete of the communities has low strength and is brittle. If it is reinforced with planting ribs, it has to be re-burrowed. If the steel is used for reinforcement, the steel has a large weight and it will imposes a heavy load on the slab itself. Therefore, carbon fiber reinforcement is recommended here. The top of the board generally refers to carbon fiber reinforcement on the upper or lower part of the floor. Generally, the mesh sticking method is adopted.
Carbon fiber is a new type of polymerized reinforcement material with a light weight of only 23% of steel. It does not burden the floor, and it does not need to be reinforced or strengthened with steel reinforcement. The floor slabs don't have to be tossed, so it can be said that it is very suitable for old buildings reinforcement.
In the process of construction, it should be noted that although the carbon fiber cloth has high strength, but the cross section is small, it is necessary to ensure that the stress of the carbon fiber cloth is extended in the correct direction during the pasting process. Generally, we will follow the direction of the stress of the steel bar and paste it in the direction of cracking to ensure correct force.
Nanjing Mankate carbon fiber cloth is a good helper for the reinforcement of the top of the board. Some projects like the strengthening of the floor of Beijing National Space Ministry Complex, Nanjing Dabaoen Temple floor slab reinforcement are reinforced with Nanjing Mankate carbon fiber cloth.
