Recoverable anchorage device for pre-stressed steel strand and installation method of recoverable anchorage device
The invention discloses a recoverable anchorage device for a prestressed steel strand and an installation method of the recoverable anchorage device, and relates to the technical field of prestressed anchorage devices. According to the anchorage device, an anchoring section of the anchorage device comprises a protective sleeve, a limiting sleeve, an end cover, a sealing cylinder, an outer ring fixing anchor plate, inner ring movable anchor plates, an anchoring end working clamping piece, a sealing baffle, an anchoring guide head, an anchoring reinforcing plate, a connecting rod, a fixing rod and a wire separating plate, wherein the protective sleeve is connected with the limiting sleeve, a threaded section of the limiting sleeve penetrates through the end cover and is screwed by means of a locking nut, the wire separating plate penetrates through the protective sleeve, tensioning steel strands or auxiliary steel strands penetrate into the protective sleeve, all the steel strands are exposed out of the inner end face of the end cover by a certain distance, an isolation plate, the outer ring fixing anchor plate and the inner ring movable anchor plates are sequentially installed, then the tensioning steel strands penetrates into the working clamping piece, the working clamping piece is hammered tightly, the sealing cylinder, the sealing baffle and a connecting sleeve are welded, the end cover is mounted, and then the connecting rod is connected with the sealing baffle, the anchoring reinforcing plate and the anchoring guide head separately. The anchorage device is high in bearing capacity, convenient to recycle, high in recycling rate and high in installation and construction efficiency.
本发明公开了一种预应力钢绞线用可回收锚具及其安装方法，涉及预应力锚具技术领域，其锚固段包括护套管、限位套、端盖、密封筒、外圈固定锚板、内圈固定锚板、锚固端工作夹片、密封挡板、锚固导向头、锚固加强板、连接杆、固定杆和分丝板；将护套管与限位套连接，限位套螺纹段穿过端盖并通过锁紧螺母扭紧；将分丝板穿过护套管，护套管内穿入张拉钢绞线或辅助钢绞线，使各钢绞线露出端盖内端面一定距离；依次安装隔离板、外圈固定锚板、内圈活动锚板，接着将工作夹片穿入张拉钢绞线并锤紧；焊接密封筒、密封挡板、连接套，安装端盖，再将连接杆分别连接密封挡板、锚固加强板、锚固导向头。本锚具承载力高、回收方便、回收率高、安装施工效率高。
