Beam member prestress bending-resistant reinforcing structure and method
The invention provides a beam member prestress bending-resistant reinforcing structure and method.The structure comprises an SMA member, a beam member, a pre-stress component and a pre-stress component, and the SMA member is in a pre-deformation state and used for receiving thermal excitation; the first fixing part is fixed with one end of the SMA component; the second fixing part is fixed with the other end of the SMA component; the first bonding area is used for fixing the first fixing part and the beam type component; the second bonding area is used for fixing the second fixing part and the beam type component; the heating device is arranged between the SMA component and the beam type component and is used for providing thermal excitation for the SMA component; the filling layer is arranged on the two sides of the middle position of the SMA component, and the thickness of the filling layer is the same as that of the first fixing part and the second fixing part; the packaging layer is arranged on the side, away from the beam type component, of the SMA component and used for packaging the first fixing part, the second fixing part and the filling layer. The method adopts the structure. The method can be widely applied to beam member crack repairing and reinforcing projects.
本发明提供了一种梁式构件预应力抗弯加固结构及方法，该结构包括：SMA构件，所述SMA构件处于预变形状态，用于接受热激励；第一固定部，与所述SMA构件的一端固定；第二固定部，与所述SMA构件的另一端固定；第一黏结区，用于将所述第一固定部与梁式构件固定；第二黏结区，用于将所述第二固定部与梁式构件固定；加热装置，布置在所述SMA构件与梁式构件之间，用于为所述SMA构件提供热激励；填充层，设置在SMA构件中间位置的两侧，且与第一固定部以及第二固定部的厚度相同；封装层，设置在所述SMA构件远离所述梁式构件的一侧，用于封装所述第一固定部、所述第二固定部和所述填充层。该方法采用上述结构。本发明可广泛适用于梁式构件裂缝修复加固工程中。
