Carbon fiber carbon cloth is a reinforcement material for large buildings, and is widely used in bridges and concrete structures such as beams and columns. It is a very mature way in the concrete reinforcement scheme, because the carbon fiber carbon cloth has obvious advantages. Its own weight is light. The specific gravity is 23% of the steel. The tensile strength can be up to 8 times steel, and it can be bent and wound and suitable for the reinforcement of various curved surfaces and special-shaped components. So it shines in the concrete reinforcement industry. Are all the concrete diseases reinforced with carbon fiber carbon cloth? That may not be.
First of all, if the deformation of the building structure is serious, it should not be reinforced with carbon fiber carbon cloth. Because the carbon fiber carbon cloth is relatively lagging behind the building structure, if it is used for the slab reinforcement project with insufficient bearing capacity to form a large deformation. Not only can the slab not improve the bearing capacity and seismic performance, but also deteriorate the original situation, resulting in more serious deformation. However, there are some remedies. In addition to the carbon fiber carbon cloth reinforcement method, you can also consider the use of the reinforcement of planting bar adhesive, the increase of the section method, or the direct reinforcement, thereby improving the rigidity of the building structure.
Carbon fiber carbon cloth is a good helper for floor cracks.
Secondly, when the rigidity of the building structure itself is insufficient, the carbon fiber carbon cloth can not be used to improve the rigidity. On the contrary, because the carbon fiber carbon cloth has low utilization rate and poor effect, the engineering is delayed and the carbon fiber carbon cloth reinforcement material is wasted, and the later rework and the funding and energy of maintenance are increased. Some building components themselves have insufficient rigidity and low pressure resistance. If the carbon fiber carbon cloth is hardly attached, the construction load will not be correspondingly affected, and the carbon fiber carbon cloth can only be wasted.
Third, when the shearing force of the building structure is relatively large, it can no longer be reinforced with carbon fiber carbon cloth. Everyone knows that carbon fiber carbon cloth has strong tensile strength, but sometimes there will be large shearing force when there is a problem in the building. Especially if the shearing force is perpendicular to the building component, this time, carbon fiber carbon cloth is attached, and the tensile strength is applied. The force will balance with the building components. In this case, even if the carbon fiber carbon cloth is successfully reinforced, it is stable for a while and cannot be long-lasting.
Carbon fiber carbon cloth reinforcement also has his limitations. It can’t be used in any case. It will only lead to shorten the service life of buildings and more serious unsafe factors. Therefore, it is recommended to consult us before making carbon fiber carbon cloth reinforcement. We will give professional guidance, and give a free calculation book, phone: 400-894-5118.
