Prestress construction method in beam-slab-free floor slab
The invention belongs to the technical field of prestress construction, and particularly discloses a construction method of prestress in a beam-slab-free floor slab, a podium building and a plurality of towers forming local fences along the periphery of the podium building are included, the podium building is in lap joint with each tower, and prestress is formed at the lap joint. The podium building and the lap joint position of the podium building and the tower building are divided into a plurality of areas in the prestress direction; a plurality of prestressing forces are formed along the districts, and transverse prestressing forces and/or vertical prestressing forces between the podium building and the tower building are/is formed in each district; pre-stress construction is conducted, specifically, corresponding pre-stress tensioning is conducted along each area, and the pre-stress tensioning adopts a tensioning method that one-time tensioning is conducted to reach a designed tension value; in the pre-stress construction, the construction sequence of the multiple areas is that vertical pre-stress is firstly constructed, and then transverse pre-stress is constructed. The method has the effects of reducing the project construction cost, improving the construction quality and accelerating the project construction progress.
本发明属于预应力施工技术领域，具体公开了无梁板楼板中预应力的施工方法，包括裙楼以及沿裙楼外周形成局部围挡的若干塔楼，所述裙楼与每个塔楼搭接，且所述搭接处形成预应力，所述施工方法包括以下步骤；预应力分区：将所述裙楼以及裙楼与塔楼搭接处，沿预应力方向，分割为若干片区；沿片区，形成若干个预应力，且每个片区形成裙楼与塔楼之间的横向预应力和/或竖向预应力；预应力施工：沿每个所述片区，进行对应的预应力张拉，且预应力张拉采用一次张拉至设计拉力值的张拉方法；所述预应力施工中，若干个片区的施工顺序为先施工竖向预应力，再施工横向预应力。本发明具有降低项目施工成本，提升施工质量、加快工程施工进度的效果。
