Outward-extending clamping piece type anchorage device of prestressed carbon plate
The invention discloses an overhanging clamping piece type anchorage device of a prestressed carbon plate. The overhanging clamping piece type anchorage device can be applied to bending reinforcement and crack control of large-span structures, beams and plates in bridge engineering and constructional engineering. The anchorage device is composed of an anchor plate 1 with a taper hole and two wedge-shaped clamping pieces 2. Through the outwards-extending clamping pieces at the two ends of the anchor plate, the anchor plate hole ends 4 and the inverted smooth fillets at the clamping face ends 5 of the clamping pieces, stress concentration at the ends of the clamping pieces is greatly reduced, meanwhile, the anchor plate is leveled through the level bubble to avoid torsional damage when the carbon plate is tensioned, and the problem that the strength utilization rate of the carbon plate is low is solved. The carbon plate 3 is anchored by increasing friction force, so that the durability of the anchorage device is guaranteed, the construction procedure is simplified, the construction period is shortened, the operation is convenient and fast, and the problems that the anchorage device is heavy, the material consumption is large and the cost is high are solved.
本发明公开了一种预应力碳板的外伸夹片式锚具，可应用于桥梁工程及建筑工程中大跨度结构、梁、板的抗弯加固，裂缝控制。提出的锚具由带锥孔的锚板1和两个楔形夹片2组成。通过锚板两端外伸夹片和锚板孔端4、夹片的夹持面端部5倒平滑圆角，大幅降低夹片端部的应力集中，同时通过水准气泡调平锚板避免碳板张拉时发生受扭破坏，改善碳板强度利用率低的问题。取消粘结胶在锚具中的使用，通过增大摩擦力的方式锚固碳板3，避免传统粘结方法的脱胶破坏与老化剥离破坏，使锚具耐久性有了保障，简化施工工序、缩短工期、操作便捷，解决了锚具笨重、材料用量大、成本高昂的问题。
