Carbon fiber structural reinforcement plays a huge role in the construction industry. If there are some cracks in the floor during pouring, can it be reinforced in this case, and will it be effective after reinforcement? What aspects should be paid attention to when using structural carbon fiber cloth to reinforce the floor slab?

1.When pouring, it was found that the floor slab had cracks, can it be reinforced?

This question actually requires a specific analysis of specific issues. If there are cracks in the cast-in-place slab, the cause of the cracks needs to be found first.

1). If it is a general crack, because it does not affect the quality and safety of the project, we need to repair the crack first, and then we can carry out carbon fiber reinforcement, and the effect is the same. It will not have a big impact on the stability and safety of the floor.

2). If the cracks are relatively large, they have seriously affected the safety of the house, and structural cracks have appeared, which must be paid attention to. Need to be reinforced. When using structural carbon fiber to reinforce, if it is a single crack, in addition to the bonding of the crack, it must be in the direction perpendicular to the crack. Use the width of the cloth to paste, and at the same time, use the method of crossing each other to paste, so that the effect can be better.

3). If there are different cracks, different remedial measures should be taken according to the impact caused. It is necessary to do a test and appraisal. In this way, the safety of the house will not be affected, and the safe use of the house in the future can also be ensured.

2. What aspects should be paid attention to when strengthening the floor slab

1) The location of the floor slab is more important. Generally, it is pasted under the floor. Because the bearing capacity of most floor slabs is in the middle part or the direction of downward force, the lower part can be pasted to improve the bending resistance.

2) When reinforcing with carbon fiber cloth, the bearing structure on most structures should be removed first. Because the bearing capacity of carbon fiber cloth is not particularly strong, it can only play a strong performance before reinforcement.
