Stress supplementing method for prestressed carbon fiber plate
The invention relates to a stress supplementing method for a prestressed carbon fiber plate. The stress supplementing method comprises the following steps of: placing jacks between a concrete component and the prestressed carbon fiber plate which is positioned below the concrete component and is used for reinforcing the concrete component, and carrying out jacking; after the jack carries out jacking to a certain jacking amount, arranging a roller shaft of which the diameter is matched with the jacking amount of the jack is in the middle of the prestressed carbon fiber plate of the concrete component; and then, removing the jacks, and filling a gap generated between the concrete component and the prestressed carbon fiber plate with structural adhesive. According to the stress supplementing method for the prestressed carbon fiber plate, one component, i.e., the roller shaft, is increased, so that the lost prestress of the component can be effectively supplemented while no carbon fiber plates need to be increased, the utilization efficiency of the original carbon fiber plate is effectively improved, the reinforcing cost of the concrete component is reduced, practicability is extremely high, and the stress supplementing method can be widely popularized.
本发明涉及一种预应力碳纤维板应力补充方法，将千斤顶置于混凝土构件与位于混凝土构件下方、用于加固该混凝土构件的预应力碳纤维板之间并进行顶升，待千斤顶顶升至一定顶升量时，将直径与千斤顶的顶升量相匹配的辊轴置于混凝土构件的预应力碳纤维板之间，再卸除千斤顶，再采用结构胶对混凝土构件与预应力碳纤维板间产生的间隙进行填补。本发明的一种预应力碳纤维板应力补充方法，通过仅增加辊轴一个部件，就能实现在避免新增碳纤维板的同时，有效补充构件损失的预应力，有效提升原碳纤维板的利用效率，降低混凝土构件加固的成本，实用性极强，可大范围推广。
