Tensioning and locking device for prestressed anti-floating anchor rod in narrow space
The invention is mainly applied to the technical field of construction of a post-tensioned prestressed anti-floating anchor under a foundation slab, and particularly relates to a tensioning and locking device for a prestressed anti-floating anchor in a narrow space, the locking device sleeves the top of a sleeve connecting device, the sleeve connecting device comprises a positioning pipe, an end sleeve is arranged at the bottom of the positioning pipe, and a connecting inner pipe is arranged at the top of the positioning pipe; an outer side flange is arranged between the connecting inner pipe and the positioning pipe, the locking assembly comprises a connecting outer pipe, a ratchet wheel and a pawl, the connecting outer pipe is sleeved on the connecting inner pipe, the ratchet wheel is sleeved on the outer side of the connecting outer pipe, the pawl is arranged on the outer side flange corresponding to the ratchet wheel, the tension loading device comprises a supporting assembly and a loading assembly, the supporting assembly is located on the outer side of the sleeve connecting device, and the loading assembly is located on the outer side of the sleeve connecting device. The top of the supporting assembly is a loading assembly. The method is suitable for tensioning and locking construction of the prestressed anti-floating anchor rod in a narrow space in which the anchorage device elevation of the prestressed anti-floating anchor rod is lower than the top elevation of a foundation raft plate, is safe and reliable, and remarkably influences the technical progress of tensioning and locking of the prestressed anti-floating anchor rod.
本发明主要应用于基础底板下后张法预应力抗浮锚杆施工技术领域，特别涉及一种狭窄空间内预应力抗浮锚杆张拉锁定装置，锁定装置套装在套管连接装置顶部，套管连接装置包括定位管，定位管底部设置端部套筒，顶部设置连接内管，连接内管与定位管之间设置外侧翼缘，锁定组件包括连接外管、棘轮及棘爪，连接外管套装在连接内管上，棘轮套装在连接外管外侧，外侧翼缘上对应棘轮设置棘爪，张拉加荷装置包括支撑组件和加荷组件，支撑组件位于套管连接装置的外侧，支撑组件顶部为加荷组件。本发明适用于预应力抗浮锚杆锚具标高低于基础筏板顶标高的狭窄空间内预应力抗浮锚杆张拉锁定施工，安全可靠，对预应力抗浮锚杆张拉锁定的技术进步产生显著地影响。
