[0002] With the development of economy and the continuous progress of technology, the design concept of housing construction has been improved day by day, and the construction technology has been continuously matured. The cast-in-place concrete floor structure has replaced the prefabricated floor structure and brick-concrete structure with its good integrity, good seismic performance and short construction period, becoming the mainstream building structure. However, the thickness of the floor plays a very important role in the safety of the building structure. The increase or decrease of the floor thickness will cause the center deflection of the floor to increase and the bearing capacity to decrease, which is also one of the main reasons for the current floor cracking. In addition, the reduction of the floor thickness will also affect a series of problems such as sound insulation, heat insulation, and vibration. In addition, the floor, as a partition component of the vertical space, plays an extremely important role, not only in terms of structural stress, but also in terms of functional use.
