Steel-concrete composite rib prestressed concrete laminated slab
The invention discloses a steel-concrete composite rib prestressed concrete laminated slab, and belongs to the field of fabricated buildings. Comprising a prestressed concrete bottom plate, and at least one upper structure is arranged on the prestressed concrete bottom plate; the upper structure comprises a steel plate structural part, the lower end of the steel plate structural part is poured in a prestressed concrete bottom plate, the steel plate structural part located above the prestressed concrete bottom plate and the prestressed concrete bottom plate define a cavity with the side faces closed, and filling materials are poured in the cavity to form concrete flanges. The invention has the advantages of high bearing capacity, high flexural rigidity, good out-of-plane stability, simplicity in manufacturing and high production efficiency, and solves the problems that the upper structure and the bottom plate of the existing laminated slab are easy to peel and damage, the flexural rigidity is low, a plurality of temporary supports are supported in the construction stage, and the concrete on the upper surface of the temporary support is easy to crack.
本发明公开了一种钢‑混凝土组合肋预应力混凝土叠合板，属于装配式建筑领域。包括预应力混凝土底板，预应力混凝土底板上设置有至少一组上部结构；上部结构包括钢板结构件，钢板结构件的下端浇筑在预应力混凝土底板内，位于预应力混凝土底板上方的钢板结构件与预应力混凝土底板围成侧面封闭的空腔，空腔内浇筑填充材料，形成混凝土翼缘。本发明承载力高、抗弯刚度大、面外稳定性能好、制作简单、生产效率高，解决了现有叠合板上部结构与底板易发生剥离破坏、抗弯刚度小、施工阶段支设临时支撑多、临时支撑处的上表面混凝土易开裂的问题。
