Large-span bidirectional prestressed concrete dense rib sandwich composite floor slab
The invention discloses a large-span bidirectional prestressed concrete dense rib sandwich composite floor slab. The composite floor slab is composed of a bottom plate, a longitudinal rib beam, a transverse rib beam and a light filling block, wherein the light filling block is clamped in a cavity formed by the bottom plate, the longitudinal rib beam and the transverse rib beam, an extension beam is arranged at an upper end of the longitudinal rib beam, transverse reinforcing steel bars are arranged between the extension beams in a suspended mode, grouting through holes used for transverse post-tensioned prestress construction are formed in the transverse rib beams, a plurality of stirrups which are longitudinally arranged are arranged on the longitudinal rib beams and the extension beams, connecting reinforcing steel bars are inserted into the grouting through holes, and post-poured concrete is used for connecting the composite floor slabs. The composite floor slab is light in dead weight, convenient to carry, low in manufacturing cost and good in heat preservation effect, the post-poured concrete and the composite floor slab can be stably combined in a two-way mode, and the floor slab is high in structural strength and not prone to cracking.
本发明公开了一种大跨度双向预应力砼密肋夹心叠合楼板，其中复合轻质砼密肋夹心叠合楼板由底板、纵向肋梁、横向肋梁和轻质填充块组成，轻质填充块夹在由底板、纵向肋梁和横向肋梁形成的空腔之中，所述纵向肋梁上端设置延伸梁，所述延伸梁之间悬空设置横向钢筋，所述横向肋梁内部设置用于横向后张预应力施工的注浆通孔，纵向肋梁和延伸梁上设置若干纵向排布的箍筋，注浆通孔内部插入连接钢筋，后浇混凝土进行叠合楼板之间的连接，本发明中的叠合楼板自重较轻，便于搬运，制造成本低、保温效果佳，且后浇砼与叠合楼板之间的可稳固双向结合，楼板结构强度大且不易开裂。
