Quick tensioning device for prestressed anchor rods and construction method
The invention relates to a quick tensioning device for prestressed anchor rods and a construction method. The quick tensioning device comprises a base, a center penetrating oil cylinder arranged on the base, a fixing ring detachably connected to the upper end of a piston barrel of the center penetrating oil cylinder, a plurality of guide rails fixed to the upper side of a fixing disc in a radial shape with the piston barrel of the center penetrating oil cylinder as the center, a plurality of sliding blocks connected to the guide rails in a sliding mode and a driving assembly synchronously driving all the sliding blocks to be close to or away from the center penetrating oil cylinder along the guide rails, and clamping plates are fixed to the sides, facing the center penetrating oil cylinder, of the sliding blocks; and an anchor rod passing hole is formed in the middle of the base, and a wrench passing space is formed in the side face of the base. The quick tensioning device has the advantages that the quick tensioning device can be suitable for the anchor rods of different specifications, and the limitation is small.
本发明涉及一种预应力锚杆快速张拉装置及施工方法，包括底座、设置在底座上的穿心油缸、可拆卸连接在穿心油缸的活塞筒上端的固定环、若干以穿心油缸的活塞筒为中心呈放射状固定在固定盘上侧的导轨、若干分别滑移连接在各个导轨上的滑块以及同步驱动各个滑块沿导轨靠近或远离穿心油缸的驱动组件，所述滑块朝向穿心油缸的一侧固定有夹板；所述底座中部设有锚杆通过孔，所述底座侧面设有扳手通过空间。本发明的优点是：可以适用于不同规格的锚杆，局限性较小。
