Prestressed carbon fiber plate anchorage device system and construction method thereof
The invention provides a prestressed carbon fiber plate anchorage device system and a construction method thereof, and belongs to the technical field of building reinforcement, the prestressed carbon fiber plate anchorage device system comprises a clamp, a tensioning sliding rail, a tensioning support, a tensioning anchor plate, a fixed anchor plate and a carbon fiber plate, the clamp comprises a pressing plate and a bottom plate, the bottom plate is provided with a curved surface groove for accommodating a carbon fiber plate, and the groove bottom of the curved surface groove comprises a first inclined surface, an inner concave arc-shaped surface and a first horizontal surface which are sequentially connected from front to back; the lower end of the pressing plate is provided with a shape follow-up face matched with the groove bottom of the curved surface groove. According to the prestressed carbon fiber plate anchorage device system, the inwards-concave arc-shaped surfaces are arranged at the lower ends of the curved-surface groove and the pressing plate, and the front sections of the inwards-concave arc-shaped surfaces are in linear gradient transition, so that the carbon fiber plate cannot be cut off by a notch effect caused by matching of the pressing plate and the bottom plate, the clamp can be easily disassembled, large-force-value tensioning is achieved, and the service life of the carbon fiber plate is prolonged. And the required tensioning space is small.
本发明提供了一种预应力碳纤维板锚具系统及其施工方法，属于建筑加固技术领域，其中预应力碳纤维板锚具系统包括夹具、张拉滑轨、张拉支座、张拉锚板、固定锚板和碳纤维板，夹具包括压板和底板，底板上开设有用于容纳碳纤维板的曲面槽，曲面槽的槽底包括自前向后依次连接的第一倾斜面、内凹弧形面和第一水平面；压板的下端具有与曲面槽的槽底相适配的随形面。本发明提供的预应力碳纤维板锚具系统，通过在曲面槽和压板的下端设置内凹弧形面且在内凹弧形面的前段采用直线坡度过度，保证了碳纤维板不会被压板和底板配合导致的切口效应剪断，且夹具可以轻松拆卸，实现了大力值张拉，所需张拉空间小。
