Prestressed beam rapid tensioning structure and construction method thereof
The invention relates to the field of building construction, in particular to a prestressed beam rapid tensioning structure and a construction method thereof, and solves the problem that tensioning ribs of a delayed coagulation binder are easy to retract when losing external force in the curing process of the delayed coagulation binder, so that the prestress applied to a prestressed beam by the tensioning ribs is insufficient. The structure comprises a plurality of tensioning ribs arranged in a prestressed beam in a penetrating manner, the two ends of each tensioning rib extend out of the end of the prestressed beam, anchor heads are connected to the two ends of each tensioning rib, each tensioning rib is provided with a fixing frame between the end of the prestressed beam and the corresponding anchor head, one side of each fixing frame is connected with a first anchor plate, the multiple tensioning ribs are arranged on the first anchor plates in a penetrating manner, the multiple tensioning ribs are sleeved with rotating blocks, and each rotating block is in external threaded connection with a first threaded sleeve. The structure has the effects that the tensioning ribs are prevented from retracting in the curing process of the delayed coagulation binder, and it is guaranteed that the tensioning ribs provide enough prestress for the prestressed beam.
本申请涉及建筑施工的领域，尤其是一种预应力梁快速张拉结构及其施工工法，解决了缓凝粘结剂的张拉筋在缓凝粘结剂固化的过程中易在失去外力时回缩，使张拉筋对预应力梁施加的预应力不足的问题，其包括穿设于预应力梁中的多根张拉筋，每一所述张拉筋两端均伸出预应力梁端部外，每一所述张拉筋两端均连接有锚头，每一所述张拉筋于预应力梁端部和锚头间均设有固定架，所述固定架一侧连接有第一锚板，多根所述张拉筋均穿设于所述第一锚板上，多根所述张拉筋上均套设有转动块，每一所述转动块外螺纹连接有第一螺纹套。本申请具有防止张拉筋在缓凝粘结剂固化过程中回缩，保证张拉筋对预应力梁提供足够的预应力的效果。
