Application of Plastic Formwork with Dense Ribs for Large-scale Basement Floors
The demountable plastic formwork with dense ribs floor system is widely used in various large buildings and long-span structures due to its excellent economic benefits. This force-bearing structure is composed of a detachable formwork shell and densely ribbed beam-slab system, which has many advantages such as reusable use, low cost, fast construction speed, and beautiful appearance. It has gradually replaced the traditional beam-slab structure system in recent years. This paper briefly analyzed the construction structure design, material selection, process arrangement, the formwork and support system, the formwork layout, installation and removal process, the main rib beam and secondary rib reinforcement construction, concrete pouring and maintenance, and other major construction methods in the practical application of plastic formwork ribbed floor system in large-scale basement engineering.
