CFRP plate multi-point anchoring system based on side faces and construction method of CFRP plate multi-point anchoring system
The invention discloses a CFRP plate multi-point anchoring system based on side faces and a construction method of the CFRP plate multi-point anchoring system, belongs to the technical field of building construction, and aims to solve the problems that the effective prestress of other parts in the longitudinal bridge direction is low and the reinforcing effect is not obvious due to the fact that deformation of prestressing tendons can be dispersed to the whole length of an inhaul cable. Tensioning devices are arranged on the two symmetrical sides of a beam body in the length direction of the beam body correspondingly, each tensioning device comprises at least three anchorage devices which are linearly arranged at intervals, the anchorage devices are installed through embedded steel bar bolts arranged on the beam body, the CFRP plates are anchored on the side faces of the beam body in a multi-point mode, and the CFRP plates are low in expansion rate. The prestressed CFRP plate anchoring method is simple and practical, can thoroughly solve the anchoring problem in the reinforcement of the prestressed CFRP plate, can greatly improve the cracking, yield and ultimate load of the beam, and also greatly improves the deformation performance.
本发明公开了一种基于侧面的CFRP板多点锚固系统及其施工方法，属于建筑施工技术领域，以解决预应力束变形会分散到拉索全长，从而导致纵桥向其他部位的有效预应力较低，加固效果不明显的问题，该发明通过在梁体对称的两侧并分别延其长度方向设置张拉装置，而张拉装置包括延直线间距设置的至少三个锚具，锚具通过梁体上设置的植筋螺栓安装，通过利用在梁体侧面多点位的锚固CFRP板，以及CFRP板伸缩率低的特点，保证整体预应力的施加，简单、实用，能彻底解决预应力CFRP板加固中的锚固问题，并且可以使梁的开裂、屈服、极限荷载均有较大幅度的提高，且在变形性能方面也有较大的改善。
