Prestressed carbon fiber plate reinforcing beam device and method based on self-anchoring type anchoring system

BAI YULEI / SHI WENHAO / JIA JUNFENG

The invention discloses a prestressed carbon fiber plate reinforcing beam device and method based on a self-anchoring type anchoring system. The prestressed carbon fiber plate reinforcing beam device is provided with a rectangular notch, a sleeve, a self-locking anchor ring, a common anchor ring, a gear and an end nut, wherein the rectangular notch is used for anchoring a carbon fiber plate; the sleeve is used for clamping the carbon fiber plate; the self-locking anchor ring is provided with a locking rod, a spring, a lock catch and a chemical anchor hole and is used for providing self-locking and anchoring an anchor when the carbon fiber plate is tensioned; the common anchor ring is provided with a chemical anchor hole and is used for anchoring the anchor; the gear is used for assisting in self-locking; and the end nut is used for fastening the anchor. When the prestressed carbon fiber plate reinforcing beam device is applied, the prestressed carbon fiber plate reinforcing beam devices need to be arranged at the two ends of a reinforcing beam according to the even number, after fixing, the thermoplastic carbon fiber plate needs to be heated in advance to be softened, the softened part is coated with carbon fiber plate glue to be wound to a roller to be shaped and cured, a torque wrench or other torque devices are used for being in butt joint with an anchor polygonal hole to apply torque, and prestress is applied to the carbon fiber plate. The prestressed carbon fiber plate reinforcing beam device is flexible and convenient to operate, scientific, efficient and beneficial to fixing, and application of the thermoplastic carbon fiber plate in structure reinforcing can be achieved.

本发明公开了一种基于自锚式锚固系统的预应力碳纤维板加固梁装置及方法，设置有矩形槽口，用于锚固碳纤维板；套筒，用于卡位碳纤维板；自锁锚环，设置有锁杆、弹簧、锁扣和化学锚栓孔，用于张拉碳纤维板时提供自锁以及锚固锚具；普通锚环，设置有化学锚栓孔，用于锚固锚具；齿轮，用于协助进行自锁；端螺母，用于紧固锚具；本发明应用时需按偶数数量布置于加固梁两端，固定好后需预先通过加热热塑性碳纤维板软化，在软化部位涂抹碳纤维板胶缠绕至滚轮后塑形固化，使用扭矩扳手或其他扭矩装置与锚具多边形孔进行对接施加扭矩，并以此对碳纤维板施加预应力。本发明操作灵活方便，科学高效，利于固定，可实现热塑性碳纤维板在结构加固中的应用。
