Fiber cloth prestress applying device for shear-resistant reinforcement and reinforcement method
The invention discloses a fiber cloth prestress applying device for shear resistance reinforcement and a reinforcement method. The prestress applying device comprises an L-shaped connecting piece, a tensioning shaft, a tensioning screw rod, a steering shaft, a nut, a fixing anchorage device and fiber cloth. During reinforcement, firstly, the tensioning shaft, the tensioning screw rod and the L-shaped connecting piece are assembled; secondly, the fiber cloth is bent oppositely around the tensioning shaft and then penetrates through a gap between the steering shaft and the reinforcing component, and the L-shaped connecting piece is fixed to the reinforcing component; then winding the end part of the fiber cloth on a fixing anchorage device, and fixing the fixing anchorage device on the reinforcing component; and after the fiber cloth is coated with the impregnating adhesive and is fully impregnated, the nut is rotated through the torque wrench to realize the application of prestress. According to the method, the shear bearing capacity is improved, inclined crack development is restrained, complex tensioning equipment and grooving on the concrete surface are not needed, construction is easy and rapid, and the reinforcing efficiency is high.
本发明公开了一种用于抗剪加固的纤维布预应力施加装置及加固方法，该预应力施加装置包括L形连接件、张拉轴、张拉螺杆、转向轴、螺母、固定锚具和纤维布。本发明在加固时，首先将张拉轴、张拉螺杆和L形连接件进行组装；其次将纤维布绕张拉轴对弯后从转向轴与加固构件之间的空隙穿过，并将L形连接件固定在加固构件上；然后将纤维布端部缠绕在固定锚具上，并将固定锚具固定在加固构件上；对纤维布涂抹浸渍胶并充分浸渍后，通过扭力扳手旋转螺母实现预应力的施加。本发明不仅提高了抗剪承载力，抑制斜裂缝发展，而且不需要使用复杂的张拉设备及对混凝土表面开槽，施工简单快速，加固效率高。
