Tensioning construction method on post-tensioning method unbonded prestressed tendon beam
The invention provides a tensioning construction method on a post-tensioning method unbonded prestressed tendon beam, and belongs to the technical field of building construction. The construction method is characterized in that a prestressed steel strand is pre-buried in the prestressed beam, and the tensioning end of the prestressed steel strand extends outwards from a tensioning groove formed in the beam top of the prestressed beam; tensioning equipment is conveyed to the prestressed beam; and the tensioning end of the prestressed steel strand is tensioned through the tensioning equipment. Therefore, the technical effect of quickly conveniently and safely completing tensioning construction is achieved.
本发明提供一种后张法无粘结预应力筋梁上张拉施工方法，属于建筑施工技术领域，本发明通过在预应力梁内预埋预应力钢绞线，预应力钢绞线的张拉端自设置在预应力梁的梁顶处的张拉槽向外延伸；将张拉设备运送至预应力梁上；利用张拉设备对预应力钢绞线的张拉端进行张拉操作；进而达到快捷安全地完成张拉施工的技术效果。
