Tensioning and anchoring device of prestressed CFRP plate reinforced beam and use method thereof
The invention discloses a tensioning and anchoring device of a prestressed CFRP plate reinforced beam and a use method thereof. The device comprise a CFRP plate, an anchoring assembly and a tensioningassembly; the tensioning assembly comprises tensioning sliding chambers, a second clamp, a fixed plate and a tensioning mechanism; and the contact surfaces of a telescopic plate and the second clampare provided with sawteeth facing oppositely. According to the device and the method, two groups of clamps fixedly clamped at two ends of the CFRP plate are installed in two groups of sliding chambersto apply the prestress, so that the eccentric tension can be prevented, the self-locking of the CFRP plate after the prestress is applied is realized through the mutual matching of the sawteeth between the telescopic plate and the second clamp, and the retraction of the CFRP plate is limited. The CFRP plate is mechanically clamped through the clamps, the anchoring efficiency is high, the qualityperformance is stable, and the high-strength performance of the CFRP plate can be fully exerted. After the prestress is applied, a jack can be dismantled, the design is integrated, the operation process is simple and convenient, and the working efficiency is improved.
本发明公开一种预应力CFRP板加固梁的张拉锚固装置及其使用方法，包括CFRP板、锚固组件和张拉组件；张拉组件包括张拉滑膛、第二夹具、固定板以及张拉机构；伸缩板与第二夹具两者接触面上设置有朝向相反的锯齿。本发明将两组固定夹持在CFRP板两端的夹具安装在两组滑膛内进行预应力的施加，可防止张紧力偏心，并通过伸缩板与第二夹具两者之间的锯齿相互配合实现了施加完预应力后CFPR板的自锁，限制CFPR板的回缩。通过夹具对CFPR板进行机械夹持，锚固效率高、质量性能稳定，可充分发挥CFRP板的高强性能。施加完预应力后即可拆除千斤顶，一体化设计、简便操作过程，提高了工作效率。
