Problems solved by technology
However, the internal reinforcement of thick slabs is complex, generally three-layer and three-directional reinforcement, and usually larger hidden beams are arranged in the slab to connect the frame columns, which makes more reinforcement at the joints and requires more on-site construction technology. High, it is easy to cause the concrete at the joints to be vibrated not densely when pouring on site, thus forming weak parts
In addition, due to the large size of the thick plate itself, formwork support and demoulding are both a huge project, which consumes a lot of construction time and is not economical, and does not meet the requirements of green buildings

The invention discloses a prefabricated floor system for thick plate conversion. An existing thick plate is complex in internal reinforcement, weak parts are easily formed during pouring, and a large amount of construction time needs to be consumed for formwork erecting and demolding. The structure comprises a plurality of reinforced concrete columns and reinforced concrete beams, and the reinforced concrete columns are in bolted connection through the reinforced concrete beams; thick plates are arranged in closed areas formed by the reinforced concrete beams and the reinforced concrete columns; and the thick plate is connected with the reinforced concrete beam through a bolt connecting piece. All the components are connected through bolts to form strong joints, an overall stress piece is formed through cast-in-place concrete, a plate-beam-column force transmission mechanism is formed in the thick plate, and the structural anti-seismic property is improved; the process of formwork erecting and demolding is omitted, the construction period is shortened, meanwhile, cost is saved, and construction pollution is reduced.
Description
technical field [0001] The invention belongs to the technical field of construction engineering, and particularly relates to a prefabricated floor system for thick plate conversion. Background technique [0002] Problems such as the large demand for land in rail transit depots and the shortage of urban land resources have made the development model of properties on top of subway depots an inevitable trend in the intensive use of urban land, and it is also one of the key tasks of the current and future rail transit industry. Generally speaking, there is a big difference between the development formats under the cover and under the cover. The under cover is the track and parking garage, while the cover is for residential or office buildings. The upper and lower axes are staggered a lot. Its advantages such as flexible layout of the superstructure have been welcomed by everyone in this development model. However, the internal reinforcement of the thick plate is complex, genera...
