The Technology Research On Steel Reinforcing Concrete Roofing Structure

As the fifth cube surface of building, building roof is directly under stronger sunshine and ruthless rain. How to do well building roof waterproof and structure energy save is relevant to building utility function and the people of live quality and living circumstance. In present developing society, as a very important coverage structure of the building roof, it not only suffers from wind and rain but also has function of utilizing rich sunshine energy to benefit human being and increasing areas of green land in city. In recent years, with the building roof garden in fashion, then it adds another good way to increase areas of green land in city and improve ecological environment in city. Spreading utility of solar energy of building roof it will be a bright future in how to utilize the resource of building roof which occupies a quarter of the one of development land areas in city.In recent years it has made great achievement in research and application and reached to more advanced level regarding of building roof waterproof and energy save and building roof garden in the world. But in the domestic mass construction still have all kinds of problem and shortage in building roof structure function design, although with the city being developed it brings on large of scale building construction. According to statistic more then 50% building roof exist different level leakage and it has made great inconvenience for people live, and more then 95% building in existence cannot reach construction standard on building energy save. Over 80% new adding building cannot reach the standard of building energy save. Solar energy application is still a kind of personal behavior in most area. The development and application of building roof garden also have a lot of problems. So it is a very important signification on which whether building can be good used and develop so call all along developing greenness construction is based on how to do research work well of construct design, reinforcing building roof for waterproof and energy save and construction of building roof garden, and how to set up a series of true and effective building roof structure design system.Since the building roof is in an important place in building structure, function and architecture style, according to the development trend on abroad and in the domestic, the article will do some research on waterproof and energy save and construction of roof garden of concrete building roof. It has simple discussed the signification of setting so call greenness architecture system and had more synthetic description on application of some relative measure.All of the content in my article has five sections.At first the firth section has described its research background, purpose and signification, and introduces actuality of relative research work on abroad and in the state. It has analyzed some existing problem of building roof function and described my study manner and way in my article.In the second part, in view of problem that there are serious leakage on some building roof at present in china and it has caused great inconvenience to people live and made much more waste, by analyzing leakage reason of flat building concrete roof, it stressed that shall take some protective measures to drainage, energy save structure, waterproof material and structure waterproof to solve building roof leakage. It emphasized roof waterproof shall obey on the principle of synthetic management and integrative protection. By summarizing some advanced waterproof material and technology in the state and on abroad, it has had some means for completely solving the problem of roof leakage.In the third by analyzing day and day energy consumption in the world and the trend of utility on green energy save construction, it has revealed necessity and importance of building roof energy save. And both through measures of building roof warm keeping and heat insulation and application of solar energy on roof, it has simply introduced a advanced technical trend on roof energy save, mentioned some present problems and shortages regarding of roof energy save and also had some improvement advices on that.The fourth described the development trend of roof garden and its important signification our improving city ecological environment. And by analyzing affective factor, construction layer, structure layout and etc., it proposed an architecture principle of roof garden and has analyzed its present development situation and its future development trend on abroad and in the domestic.The fifth is a conclusion in which it has summed up author's opinions and revealed relationship of concrete building roof waterproof, energy save and the afforest.
