The main load-bearing structure in concrete buildings, the damage of its structure or the lack of carrying capacity can easily cause accidents. As the concrete column grows with the use year, its rigidity, strength and load stress will change, and the damage of the concrete columns is very sudden. Therefore, the state of the concrete is regularly detected and timely targeted to the defective concrete. Column reinforcement is very necessary.
There are generally three methods for concrete column reinforcement in the construction: increasing section method, outer steel reinforcement method, and carbon fiber reinforcement method. These three methods each have their own advantages, and the applicable engineering conditions are also different. Therefore, in the process of reinforcing the concrete columns, attention should be paid to the specific needs of the engineering.
The enlarged section method is suitable for the case where the bearing capacity of the concrete column is too small, and the bearing capacity is insufficient. The steel-clad method is suitable for concrete column reinforcement that needs to greatly increase the section load capacity and seismic capacity, and can significantly improve the structural performance. Carbon fiber reinforcement method is applicable to the reinforcement of concrete columns with axial compression and large eccentric compression and insufficient ductility.
The reinforcement of concrete in the later period is very important, so in the selection of construction methods, it is necessary to carry out engineering test to carefully choose. In addition, it is the choice of reinforcement materials. The right method is selected, but the material quality can not keep up, and the later reinforcement has no effect. This situation is extremely dangerous. Here also follows the state-owned enterprises, CCTV7 "brand exhibition broadcast" and other recommendations - Nanjing Mankate Technology.
