Fabricated formwork-free box floor system and construction process thereof
The invention belongs to the technical field of building application, and particularly discloses an fabricated formwork-free box type floor system and a construction process thereof. The fabricated formwork-free box type floor system comprises a plurality of formworks, a prefabricated rib beam bottom supporting plate, a reinforced concrete prefabricated bottom plate, a cast-in-place concrete rib beam, a plurality of bottom plate steel bars, a plurality of top plate steel bars and the like. The fabricated formwork-free box type floor system and the construction process thereof have the beneficial effects that the high-strength integral bottom plate formed by combining the prefabricated reinforced concrete bottom plate and the prefabricated rib beam bottom supporting plate is fully utilizedas a formwork, a large-area special floor formwork does not need to be laid any more, the formwork exemption rate reaches 85% or above, the purposes of reducing the self weight and saving reinforced concrete are achieved, and the formwork cost is further saved; the box type floor system is high in bearing capacity and light in self weight, the prefabricated part and the cast-in-place concrete ribbed beam are firmly combined and good in integrality, and the stress performance is better than that of the cast-in-place reinforced concrete ribbed floor system; and engineering application can greatly save steel bars, concrete and formworks, the on-site concrete pouring amount is small, the construction speed is high, and the manufacturing cost is obviously saved.
本发明属于建筑应用技术领域，具体公开了一种装配式免模板箱型楼盖及其施工工艺，包括若干个模架、预制肋梁底托板、钢筋混凝土预制底板、现浇混凝土肋梁、若干根底板钢筋和若干根顶板钢筋等。本发明的有益效果在于：充分利用了预制钢筋混凝土底板和预制肋梁底托板组合形成的高强度整体底板做为模板，不再需要大面积专门铺设楼盖模板，模板免除率达到85%以上，既实现了减轻自重节约钢筋混凝土的目的，又进一步节约模板费用；箱型楼盖承载力高、自重轻、预制构件和现浇混凝土肋梁结合牢固，整体性好，受力性能比现浇钢筋混凝土密肋楼盖效果更佳；工程应用可大量节约钢筋、混凝土和模板，现场混凝土浇筑量小，施工速度快，造价节约明显。
