Reinforced concrete deep beam prestress composite reinforcing device and construction method thereof
The invention provides a reinforced concrete deep beam prestress composite reinforcing device and a construction method thereof. The reinforced concrete deep beam prestress composite reinforcing device adopts a mode of combining angle steel, prestress steel wire bundles and sprayed fine aggregate concrete, and comprises bottom angle steel positioned on two sides of the bottom of a reinforced concrete deep beam and top angle steel positioned on two sides of a top floor slab of the reinforced concrete deep beam; the prestressed steel wire bundles are bound outside the top angle steel and the bottom angle steel and are fixed to a floor slab. According to the device, the prestress provided by the prestressed steel wire bundles is adopted to counteract part of the internal force of the original deep beam, and the restraining effect of the prestressed steel wire bundles on the original deep beam is utilized to a great extent, so that the shear bearing capacity of the deep beam is greatly improved; and the reinforced deep beam and a floor plate are connected more firmly, force transmission is more reliable, new and old structures can work cooperatively, and the reinforced concrete deep beam prestress composite reinforcing device can be used for reinforcing deep beams of various sizes. The reinforced concrete deep beam prestress composite reinforcing device is used for reinforcing the reinforced concrete deep beams and has relatively high engineering practical value.
本发明提供钢筋混凝土深梁预应力复合加固装置及其施工方法，采用角钢、预应力钢丝束与喷射细石混凝土相结合的方式，包括位于钢筋混凝土深梁底部两侧的底部角钢及位于钢筋混凝土深梁顶部楼板两侧的顶部角钢，所述顶部角钢与底部角钢外部绑扎有预应力钢丝束，所述预应力钢丝束固定于楼板上，本发明采用了预应力钢丝束提供的预应力抵消原深梁的部分内力，并很大程度上利用了预应力钢丝束对原深梁的约束作用，大幅提高了深梁的抗剪承载力；加固后深梁和楼面板连接更牢固，传力更可靠，使新旧结构能协同工作，可用于各种尺寸的深梁加固。本发明用途：钢筋混凝土深梁加固，具有较好的工程实用价值。
