Preparation method of steel rib prestressed concrete laminated slab hoisting structure
The invention discloses a preparation method of a steel rib prestressed concrete laminated slab hoisting structure, and belongs to the field of fabricated buildings. The steel rib and prestressed concrete laminated slab comprises a prestressed concrete bottom slab, a concrete upper flange and steel ribs, the steel ribs are located between the prestressed concrete bottom slab and the concrete upper flange, and the lower ends and the upper ends of the steel ribs are poured in the prestressed concrete bottom slab and the concrete upper flange respectively. The number of the hoisting structures is multiple, and each hoisting structure comprises a hoisting ring made of an ultra-high molecular weight polyethylene rope. During preparation, the lower portion of the lifting ring is connected with a steel rib or a transversely-distributed steel bar of a prestressed concrete bottom plate, and the upper portion of the lifting ring is located above a concrete upper flange and forms a lifting portion. The steel rib prestressed concrete laminated slab is easy to manufacture, high in production efficiency and lower in cost, the advantage of large flexural rigidity of the steel rib prestressed concrete laminated slab can be brought into full play, deformation of the prefabricated concrete bottom slab and the laminated slab is reduced, transportation and stacking are convenient, and post-pouring laminated layer concrete is convenient to pour.
本发明公开了一种钢肋预应力混凝土叠合板吊装结构的制备方法，属于装配式建筑领域。钢肋预应力混凝土叠合板包括预应力混凝土底板、混凝土上翼缘和钢肋，钢肋位于预应力混凝土底板和混凝土上翼缘之间，并且钢肋的下端和上端分别浇筑在预应力混凝土底板和混凝土上翼缘内；吊装结构的数量为多个，每个吊装结构均包括由超高分子量聚乙烯绳索制成的吊环。在制备时，吊环的下部与钢肋或预应力混凝土底板的横向分布钢筋连接，吊环上部位于混凝土上翼缘上方且形成吊装部。本发明制作简单、生产效率高、成本更低，可以充分发挥钢肋预应力混凝土叠合板抗弯刚度大的优势，减小预制混凝土底板和叠合板的变形，便于运输和堆放，便于浇筑后浇叠合层混凝土。
