Steel strand prestress loss compensation device in concrete beam
The invention discloses a concrete beam steel strand prestress loss compensation device which comprises a jack, a bottom plate and an anchoring disc, the anchoring disc is provided with an anchor hole, a clamping block is arranged in the anchor hole, the bottom plate is provided with an avoiding hole, the outer side of the bottom plate is fixedly connected with a plurality of backing rings, the bottom plate is fixedly connected with a plurality of guide columns, and the guide columns are jointly connected with a supporting ring in a sliding mode. The two-way jacking device comprises a supporting plate, the supporting plate is connected to the guiding columns in a sliding and rotating mode, a boss is arranged at the end, away from the bottom plate, of each guiding column, a supporting spring is arranged between the boss and the supporting plate, an elastic hoop plate is arranged at one end of the supporting plate, and a jacking rod assembly is arranged on one side of the elastic hoop plate. The ejector rod assembly is rotationally connected with the supporting plate. The bottom plate is jacked by the jacking rod assembly, on one hand, the bottom plate and the backing ring are pushed to the clamping block, on the other hand, the supporting plate slides on the guide column away from the clamping block, and therefore the effect of pressing and pulling the steel strand outwards at the same time is achieved.
本发明公开了一种混凝土梁中钢绞线预应力损失补偿装置，包括千斤顶、底板和锚固盘，锚固盘设置锚孔，锚孔内设置夹块，底板设有避让孔，底板外侧固定连接多个垫环，底板固定连接多个导向柱，多个导向柱共同滑动连接支撑环，导向柱轴向滑动连接双向顶压装置，双向顶压装置包括支板，支板滑动且转动连接在导向柱上，每个导向柱远离底板的一端设置凸台，凸台与支板之间设置支撑弹簧，支板一端设置弹性箍板，弹性箍板一侧设置顶杆组件，顶杆组件与支板转动连接。本发明通过顶杆组件向底板顶进，一方面对底板、垫环往夹块的推动，另一方面反作用力，使得支板在导向柱的背离夹块的滑动，从而起到一边压紧，一边将钢绞线往外拔拉的作用。
