Rotatable external prestress reinforcing device and tensioning method thereof
The invention discloses a rotatable external prestressing reinforcing device and a tensioning method thereof, the device comprises a circular anchorage device and a supporting assembly, the circular anchorage device clamps two ends of a carbon fiber plate and is connected to a fixed anchor frame through a bolt pin, and the supporting assembly is located in the midspan and is used for tensioning the carbon fiber plate. According to the external prestressing reinforcement scheme, the semicircular truncated cone-shaped clamping pieces are used, pressure is evenly applied to the carbon fiber plate, the problems of splitting and the like caused by uneven stress of the carbon fiber plate can be effectively solved, and the strength advantage of the carbon fiber plate is fully played; the rotatable tail rod is arranged and can rotate around the pin shaft by 180 degrees, so that the connection mode of the anchorage device and a to-be-reinforced structure can be enlarged and simplified, the connection cost is reduced, and the stress concentration phenomenon at the end of the carbon fiber plate is reduced; and the supporting device is used for transversely tensioning the carbon fiber plate, dependence on a jack and other heavy mechanical devices can be eliminated, implementation is convenient, and the method is widely applied to structures to be reinforced, such as bridges and the like.
本发明公开了一种可转动的体外预应力加固装置及其张拉方法，本装置包括圆形锚具和支撑组件，圆形锚具夹持碳纤维板两端，并通过销栓连接在固定锚框上，支撑组件位于跨中，用于实现张拉碳纤维板。本发明提出的体外预应力加固方案使用半圆台型夹片，对碳纤维板施加压力均匀，可以有效解决碳纤维板受力不均匀而发生的劈裂等问题，充分发挥碳纤维板的强度优势；通过设置可转动尾杆，可绕销轴180°转动，可以加大简化锚具与待加固结构的连接方式，降低连接成本，减小在碳纤维板在端部的应力集中现象；再者使用支撑装置对碳纤维板横向张拉，可以摆脱对千斤顶等重型机械装置的依赖，便于实现，用于广泛的待加固结构，如桥梁等。
