Design Method And Economic Analysis Of Reinforced Concrete Hollow Floor With Thin-wall Core Box

Cast-in-situ Conerete Hollow Floor System is a kind of new style of floor system, itsmain technique characteristics BE:Press the preparing of statute decoration certain amountnew hollow building cover system of making permanent tube body or box shutteringinside the body but formation in the cast-in-situ concrete floor slab now, have toeconomize material, ease structure own weight and apply span length big, soundproofheat preservation effective and comprehensive economic efficiency sailing over etc.advantage.The cast-in-situ concrete hollow floor now of inside the shuttering has simplifiedtube and box body, piece the body is two major types.In recent years, with simplified tubeis inside shuttering the cast-in-situ concrete hollow floor slab is a lot of in the localapplication now, the research work corresponding is also more.And with box body, piecebody for inside shuttering the cast-in-situ concrete hollow floor slab also has theapplication of equal amount in the domestic now, but as to it’s the research workdeveloping return less.《Cast-in-situ concrete hollow floor structure techniqueregulations》 started implementing in2005(CECS l75:2004), medium more the rulingrules all aim at tube body is inside shuttering of cast-in-situ concrete hollow floor, but aimat a piece of body, box body for inside shuttering of the cast-in-situ concrete hollow floornow of ruling then less.This text mainly aims at a thin wall box of beehive type embodiment cast-in-situconcrete the hollow floor carry on a research.At to privately owned research achievementsorting and the ground wok of analysis up, this text launches a research to the followingproblem:1. Analyze the applied way of thinking of device now according to the cast-in-situconcrete hollow floor inner force, put forward a thin wall box embodiment cast-in-situconcrete the hollow floor of practical design method, and Be applied to engineeringactual;2. Combine engineering actual, put forward to adopt PKPM to carry on a thin wallbox embodiment cast-in-situ concrete the hollow floor of practical design method, andcarry on structure computation and working drawing design;3. Built up5×4across of frame structure, across a degree to take a6m,8m,10mand12m respectively, live a lotus to carry to take5.0kN/m~2、10.0kN/m~2、15.0kN/m~2、20.0kN/m~2, under the different condition the economy of the hollow building coverstructure and common beam plank structure. 3. Pass engineering illustration, adopt a thin wall box of common beam and slabstructure and beehive type the embodiment cast-in-situ concrete hollow floor structuretwo kinds of different decoration pattern model, computation, reinforcement and drawing,carry on detailed comprehensive cost a comparison, discussed a thin wall box of beehivetype body the hollow floor under the different condition of apply sphere and it economicfunction.
