The invention discloses a prestressed anchorage device. The device comprises an anchor plate; one side of the anchor plate is fixedly connected with a horn pipe and a corrugated pipe in sequence; the periphery of the horn pipe and the periphery of the corrugated pipe are sleeved with a spiral rib; one end of the spiral rib is fixedly connected with the side wall of one face of the anchor plate, and the other side of the anchor plate is fixedly connected with a sleeve; the center of the anchor plate, the center of the horn pipe and the center of the corrugated pipe are each provided with a grouting hole; the center of the sleeve is fixedly connected with one end of a connecting pipe and is communicated with the connecting pipe; the other end of the connecting pipe is connected with the grouting hole in the side wall of the anchor plate; a plurality of anchor plugs are arranged on the side wall of the anchor plate and distributed in an annular array mode; a plurality of mounting holes are formed in the side walls of the horn pipe and the corrugated pipe; the mounting holes correspond to the anchor plugs one to one; a prestressed tendon is arranged in each anchor plug; and the prestressed tendons penetrate through the mounting holes to extend out of the corrugated pipe. According to the prestressed anchorage device,a clamping sheet can be stabilized, and the clamping sheet can be prevented from falling off.
本发明公开了一种预应力锚具，包括锚板，所述锚板的一侧依次固定连接有喇叭管与波纹管，且所述喇叭管与波纹管的外周套装有螺旋筋，所述螺旋筋的一端固定连接锚板的一面侧壁，所述锚板的另一侧固定连接有套筒，所述锚板、喇叭管以及波纹管的中央处均开设有注浆孔，所述套筒中央处固定连接连接管的一端并与之相连通，所述连接管的另一端与锚板侧壁的注浆孔相连接，所述锚板的侧壁开设有若干个锚塞，且所述锚塞呈环形阵列布设，所述喇叭管与波纹管的侧壁开设有若干个安装孔，且所述安装孔与锚塞一一对应，每个所述锚塞内设置有预应力筋，所述预应力筋的穿过安装孔延伸至波纹管外，本发明有利于稳定夹片，防止夹片脱落。
