Theory Calculation The Project Apply Of Hollow Concrete Buikling Cover

Presently,in the area of industry and civil architecture in china,the structure of reinforced concrete is still the most widely used architecture form in our country due to its wide-ranging material,advanced skill,low price and its strong life-force.The floorslab of reinforced concrete can be divided into the following types according to its category:rib roof beam floorslab,floorslab without roof beam,flat floorslab,floorslab with steel.However,further requirements are ordered by the high altitude,wide space,flexible intervals and antiknock of modern architecture,people are committed to reseaching the newer,more comfortable and more economical and technical system of reinforced concrete.The skill of hollow cover with concrete cast-in-place is the new skill of covering structure that developed home in recent years.It is based on the solid cover with some high-strength thin-wall tube being put in it according to certain rules.The high-strength thin-wall tube are used to replace some of the concrete,thus reduce the volume of concrete,reduce the weight of the whole structure.It is a new system after the development of common roof beam board,dense floorslab and cover without adhesive prestressing force.Since nowadays our country hasn`t got the designing standard for hollow cover with concrete cast-in-place,the article discusses the calculating method,first,calculate and analyze according to the feature of the support of reinforced concrete,then the hollow cover was shortened as and use the calculating software which designers are familiar with to work it out by computer.And the article discusses the economis function of the high-strength thin-wall tube hollow cover in different situations and the best area that this kind of cover suits.The article also expounds in detail the working technology of the hollow cover with concrete cast-in-place.
