Prestress pressure type anti-floating anchor rod and construction method thereof
The invention provides a prestress pressure type anti-floating anchor rod and a construction mode thereof, which are used in the technical field of building foundations and comprise a threaded rod body, a nut, a first steel base plate, an elastic device, a second steel base plate, an anti-corrosion corrugated sleeve, a positioner and a threaded bearing body. Prestress is applied and locked through the anchorage device, the force transmission mode, the construction mode and the prestress applying time of the prestressed anchor rod are changed, the construction efficiency is improved, the prestressed anchorage device is produced and machined in a factory in advance, operation is easy when the prestressed anchorage device is used in a construction site, and when prestress is applied, a nut can be directly screwed through a torque wrench. The requirement on site construction equipment is low, the construction technical difficulty is reduced, and popularization is easy.
本发明提供了一种预应力压力型抗浮锚杆及其施工方式，用于建筑地基基础技术领域，包括螺纹杆体、螺母、第一钢垫板、弹力装置、第二钢垫板、防腐波纹套管、定位器、螺纹承载体。采用锚具施加、锁定预应力，改变了预应力锚杆的传力方式、施工方式及施加预应力的时间，提高了施工效率，而且预应力锚具预先在工厂生产加工，施工现场使用时操作较为简单，施加预应力时可采用扭矩扳手直接拧动螺母，对现场施工设备要求低，降低了施工技术难度，易于推广。
