I believe that everyone has encountered a decoration of the house. An important part of the decoration is to understand where the load-bearing structure is. Generally, we do not recommend that you move the load-bearing structure, but sometimes when you are forced to move the structure, how do we go about conservation? For example, there is a family who recently extended their air-conditioning ducts outside the house and made a hole in the beam of the house. They wrote to NJMKT and asked if this situation would be dangerous.
Carbon Fiber Fabric
First of all, we need to determine whether the main reinforcement is damaged. If the main reinforcement is not hit, but the hole is opened in the concrete, and the hole is relatively small, it is not necessary to strengthen it. If the main reinforcement has been moved, but only a small part of it has been interrupted, you can consider using carbon fiber fabric or cladding steel to strengthen it, but it must be carried out as soon as possible, because after the house beam is deformed by the load, these two reinforcement methods are not so good. Before deforming, Carbon Fiber Fabric should be reinforced before deformation.
Then there is the worst case, that is, most of the main reinforcement is interrupted. In this case, it is no longer suitable to use carbon fiber fabric for reinforcement, because the paste steel plate and carbon fiber fabric are not suitable for the reinforcement of concrete and longitudinally stressed steel bars. It is recommended to strengthen the component with a rate of less than 0.2%. For how much reinforcement is required when increasing the cross section, you can consult a professional Chemical Anchor System Supplier: NJMKT.
