CONSTRUCTION TECHNOLOGY OF MULTI-SPAN HIGH-LOW DIFFERENCE SUBFLOOR STRUCTURE FOR SCHOOL BUILDINGS
The multi-span floor of the school building is affected by the complexity of the structure,and the problem of incomplete pouring is easy to occur during the pouring process,which affects the compressive strength of the concrete.Therefore,in order to improve the overall strength of multi-span high-low difference floor structure,the construction technology of multi-span high-low difference floor structure of school building is studied.The structure of folding contact bottom plate is designed by optimizing and adjusting the mix ratio of concrete.Then the concrete is poured in combination with the bin hopping method,and the bottom of the box is lowered and the box system is converted,and the bottom keel is lifted and recovered.Through the method of core sampling,the detection point is set up to detect the concrete strength of the bottom plate.The test results show that the compressive strength of the concrete core sample of the floor structure is above 40 MPa,which can indicate that the construction technology of the floor structure has a relatively ideal construction effect.
