Study And Mechanics Analysis About Honey Comb Core Reinforced Concrete Hollow Slab

The honey combed-core hollow floor is a new style of floor. The weight of this floor is small and the span of this floor is large. the honey combed-core hollow floor adapts the demands for the floor system of this age. It has been used in some projects and has gained great social effects and economical profits. This kind of floor system can provide flexible spaces economically, and can be used widely although the design theories are not mature.This kind of floor system belongs to the hollow reinforced concrete in which a number of prefabricated permanent high strength thin-wall core boxes are laid.At the first,the artile introdudes the hondey core hollow floor slab;Once more, this paper focused on the construction technology of floor slab with comby core, and the key and difficulty of it is to solve the problem of core floating in the pouring and displacement, and the density between comby core and concrete issue. Through specific construction project, and resolution measures about above questions.a certain amount of construction are given.At last,the elastic solution of the slab on the simple support is given using simulating sandwich plate method. According to principle of the stiffness are equivalent, honeycombed-core slab was analyzed to solid two-way slab, then the calculate method of the slab's internal fore and deflection was proposed based on the theory of thin rectangular solid elastic.
