Fabricated formwork-free box floor system and construction process thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of building applications, and in particular relates to an assembled formwork-free box-shaped floor and a construction process thereof. Background technique [0002] In order to facilitate construction and save costs, the construction industry currently widely uses bamboo, wood, and aluminum-plastic building formwork to build ribbed floors or hollow floors. These formworks generally have problems such as limited turnover times and low recycling value, especially bamboo and wood. Formwork and aluminum-plastic formwork generally have no more than 10 turnovers, resulting in a large amount of resource consumption and waste. The recycling process is also likely to cause secondary pollution, which has a greater impact on the environment. [0003] At present, the state calls for the green and low-carbon development of the construction industry and vigorously promotes prefabricated buildings. Two important indicators...

[0002] In order to facilitate construction and save costs, the construction industry currently widely uses bamboo, wood, and aluminum-plastic building formwork to build ribbed floors or hollow floors. These formworks generally have problems such as limited turnover times and low recycling value, especially bamboo and wood. Formwork and aluminum-plastic formwork, the number of turnovers generally does not exceed 10 times, resulting in a large amount of resource consumption and waste, and it is also easy to cause secondary pollution during the recycling process, which has a greater impact on the environment
