Fabricated large-span prestressed floor slab
A fabricated large-span prestressed floor slab comprises a concrete floor slab and is characterized in that bearing end beams are arranged at the two ends of the floor slab, prestressed longitudinal ribbed beams are arranged on the two sides of the floor slab, the bearing end beams and the prestressed longitudinal ribbed beams are connected to form a slab-girder frame, the concrete floor slab is arranged on the upper portion of the slab-girder frame, and the concrete floor slab is arranged on the lower portion of the slab-girder frame. Longitudinal non-prestressed upper main reinforcing steel bars are arranged on the upper portions in the prestressed longitudinal rib beams, longitudinal non-prestressed lower main reinforcing steel bars and prestressed reinforcing steel bars are arranged on the lower portions of the prestressed longitudinal rib beams, the longitudinal non-prestressed lower main reinforcing steel bars are arranged on the lower portions of the prestressed reinforcing steel bars, and the longitudinal non-prestressed lower main reinforcing steel bars and the prestressed reinforcing steel bars are fixed together through hoop fasteners. And a rib separating piece is arranged at the hoop fastening part between the longitudinal non-prestressed lower main reinforcing steel bar and the prestressed reinforcing steel bar, and the hoop fastening piece is arranged at the joint part of the prestressed longitudinal rib beam and the bearing end beam, so that the device has the characteristics of no need of high formwork erection, realization of the large-span requirement and the like.
一种装配式大跨度预应力楼板，包括混凝土楼面板，其特征在于所述的楼板两端设置有承力端梁，所述的楼板两侧设置有预应力纵向肋梁，承力端梁和预应力纵向肋梁相连接成板梁框架，所述的混凝土楼面板设置在板梁框架的上部，所述的预应力纵向肋梁内的上部设置有纵向非预应力上部主钢筋，其下部设置有纵向非预应力下部主钢筋和预应力钢筋，所述的纵向非预应力下部主钢筋设置在预应力钢筋的下部，两者之间通过卡箍紧固件固定在一起，且纵向非预应力下部主钢筋与预应力钢筋之间在卡箍紧固部位设置有隔筋件，所述卡箍紧固件设置在预应力纵向肋梁与承力端梁的交接部位，具有免高支模，实现大跨度的需求等特点。
