Post-tensioned unbonded prestressed beam dismantling method
The invention relates to the technical field of prestressed beam dismantling, in particular to a post-tensioned unbonded prestressed beam dismantling method which comprises a prestressed beam, an open anchor bearing plate assembly and an open tensioning anchorage device assembly. A supporting frame attached to the lower end face is built at the lower end of the prestressed beam; then, a releasing operation area is manually chiseled out at the position, needing to be dismantled, of the prestressed beam, a steel strand is found out, the open anchor bearing plate assembly is connected to one side of the steel strand in a sleeving mode, the open anchor bearing plate assembly and the prestressed beam are fixedly arranged in an attached mode through an anchor rod, and the releasing operation area is manually chiseled out at the joint, needing to be dismantled, of a beam body; then the steel strand is fixed in advance through the open anchor backing plate assembly and the open tensioning anchorage device, then the steel strand is cut off and matched with a hydraulic device to release prestress of the steel strand, and after the prestress of the steel strand is released, the prestressed beam becomes common concrete and can be rapidly disassembled, the operation process is simple, and due to the arrangement of open accessories, the cost is low. And connection and use are convenient.
本发明公开涉及预应力梁拆除技术领域，具体为一种后张无粘结预应力梁拆除方法，包括预应力梁、开口锚垫板组件、开口张拉锚具组件，在预应力梁的下端搭建贴合下端面的支护架，然后在预应力梁需要拆除的位置进行人工剔凿出放张操作区，并找出钢绞线，将开口锚垫板组件套接在钢绞线的一侧，并通过锚杆与预应力梁贴合固定设置，通过在梁体需要拆除的节点进行人工剔凿出放张操作区，然后通过开口锚垫板组件和开口张拉锚具对钢绞线进行先行固定，然后切断钢绞线并配合液压装置进行钢绞线的预应力释放，待钢绞线的预应力放张完成后，预应力梁变成普通混凝土，可进行快速的拆除，操作流程简单，且开口的配件设置，方便连接使用。
