LI JUNHUI / DENG JUN / HUANG WEIZHE / DENG SHENGJIE

The invention discloses a beam member prestress reinforcing device, reinforcing method and reinforcing system. The beam member prestress reinforcing device is provided with a connecting device, a first anchorage device, a second anchorage device, a CFRP member and an SMA member, the CFRP member makes contact with a beam member, one end of the CFRP member is fixed to the first anchorage device, and the other end of the CFRP member is fixed to the connecting device, one end of the SMA component in the pre-deformation state is fixed to the second anchorage device, the other end of the SMA component in the pre-deformation state is fixed to the connecting device, the first anchorage device and the second anchorage device are arranged in a spaced mode and can be fixed to the beam type component, and when the SMA component in the pre-deformation state receives thermal excitation, the SMA component recovers deformation and can drive the connecting device to move, therefore, the CFRP component is pre-tensioned by the connecting device, so that the CFRP component generates pre-stress, and the pre-stress is transmitted to the beam-type component to be reinforced. The beam member prestress reinforcing device, reinforcing method and reinforcing system can be widely applied to the field of engineering components.

本发明公开了一种梁式构件预应力加固装置、加固方法及加固系统，本发明通过设置连接装置、所述第一锚具、第二锚具、CFRP构件以及SMA构件，CFRP构件与梁式构件接触，CFRP构件一端与第一锚具固定，另一端与连接装置固定，将处于预变形状态的SMA构件一端与第二锚具固定，另一端与连接装置固定，第一锚具与第二锚具间隔设置且能够固定于梁式构件，当预变形状态的SMA构件接收热激励，SMA构件恢复形变会带动连接装置移动，从而使得连接装置对CFRP构件实现预张拉使得CFRP构件产生预应力，传递至梁式构件实现加固，本发明作为一种梁式构件预应力加固装置、加固方法及加固系统，可广泛应用于工程构件领域。
