Method for dismantling post-tensioned bonded prestressed beam
The invention relates to a post-tensioned bonded prestressed beam dismantling method which comprises a post-tensioned bonded prestressed beam, a frame column, a beam prestressed steel strand, a supporting frame body and a temporary support, the post-tensioned bonded prestressed beam needs to be dismantled due to building function adjustment, and direct dismantling can endanger the safety of constructors and possibly cause damage to the structure. According to the method, the mechanics principle is utilized, the post-tensioned bonded prestressed beam is symmetrically cut in a segmented mode from the midspan to the two sides, the prestressed steel strands of the beam are reserved in the cutting process, and after segmented cutting is completed, the post-tensioned bonded prestressed beam is symmetrically cut in a segmented mode from the midspan to the two sides till the beam is completely cut off. In the segmented step-by-step cutting process of the post-tensioned bonded prestressed beam, stress is released step by step, the stress adjusting time is reserved for a structural system, the post-tensioned bonded prestressed beam is completely cut off after the stress of the structural system is adjusted in place, and the post-tensioned bonded prestressed beam is safe, reliable and high in practicability.
本发明涉及一种后张有粘结预应力梁拆除方法，包括后张有粘结预应力梁、框架柱、梁预应力钢绞线、支撑架体、临时支撑，所述后张有粘结预应力梁由于建筑功能调整需要拆除，直接拆除会危及施工人员安全并有可能导致结构本身的破坏。本方法利用力学原理，通过对所述后张有粘结预应力梁从跨中向两边对称、分段切割，切割的过程中保留所述梁预应力钢绞线，分段切割完成后再从跨中向两边对称、分段继续切割直到梁完全切断。所述后张有粘结预应力梁在分段逐步切割的过程中，应力逐步释放，给结构体系留有应力调整的时间，待结构体系应力调整到位后完全割断所述后张有粘结预应力梁，安全可靠，实用性强。
