Variable-curvature clamping type anchorage device suitable for FRP plate and design method
The invention discloses a variable-curvature clamping type anchorage device suitable for an FRP plate and a design method. The anchorage device is suitable for a single-layer FRP plate and a multi-layer FRP plate. According to the anchorage device suitable for the single-layer FRP plate, the single-layer FRP plate is clamped between an upper clamping plate and a lower clamping plate, the upper clamping plate and the lower clamping plate are each provided with a variable-curvature waveform, the FRP plate is bent into the variable-curvature waveform, and the variable-curvature waveform is provided with an adjustable waveform and a wave crest. An upper lug plate, a lower lug plate and a clamping piece are additionally arranged on an anchorage device of a single-layer FRP plate. The design method comprises the steps that a variable curvature waveform function is designed, and an upper clamping plate, a lower clamping plate and a clamping piece are machined according to the variable curvature waveform function; mounting a lower lug plate, a lower clamping plate, an FRP plate, a clamping piece, an upper clamping plate and an upper lug plate; and the gasket and the bolt are installed, the nut is tightened to apply variable pre-tightening force to the bolt, and the FRP plate is bent into a variable-curvature waveform. According to the variable-curvature clamping type anchorage device, stress distribution in the anchorage device can be effectively improved, stress concentration of the loading end of the anchorage device is reduced, the anchoring length is shortened, and the anchoring efficiency is improved.
本发明公开了一种适用于FRP板的变曲率夹持式锚具及设计方法，锚具适用于单层FRP板及多层FRP板。适用于单层FRP板锚具是在上夹板和下夹板之间夹紧有单层FRP板，上夹板和下夹板均具有变曲率波形，FRP板弯曲成变曲率波形，变曲率波形具有可调节波形和波峰。适用于多层FRP板锚具在单层FRP板的锚具上增加了上耳板、下耳板和夹片。设计方法包括：设计变曲率波形函数，根据变曲率波形函数，加工上夹板、下夹板及夹片；安装下耳板、下夹板、FRP板、夹片、上夹板及上耳板；安装垫片和螺栓，拧紧螺母对螺栓施加变预紧力，FRP板弯曲成变曲率波形。变曲率夹持式锚具可以有效地改善锚具内的应力分布，降低锚具加载端的应力集中，缩短锚固长度，提高锚固效率。
