Research And Application Of Day Lighting Roof Technology In Practical Engineering

The research object of the paper is nanning jiangnan wanda plaza project indoor pedestrian street daylighting top, The article analyzed the daylighting top of the key technical problems in the process of design and construction. Daylighting top as the product of the combination of glass and steel structures,which Plays an important role in modern architecture. Appearing on the top of the daylighting to natural light into the interior, that makes the building energy efficiency has a new definition. At the same time, With the huge improvement of the architectural space and aesthetic for the daylighting top. First of all,the paper studied the design of the daylighting top, through the past experience of daylighting top respectively puts forward the performance index requirements, which including waterproof, fire prevention, seismic performance. All kinds of classification performance, according to the specific site conditions the performance levels of selected accordingly. Through the wind load for the daylighting top and weight of the stress distribution is calculated. Thus for the material selection of the daylighting top is given, the daylighting waterproof glue line on the top of the basis is given.The construction technology, Daylighting top the performance of various materials used material in standard is given. Then respectively for elliptic daylighting top and corridor lighting division of the decomposition, the installation plan is given out. Finally, the installation is complete the daylighting of the roof hanging experiment analysis, through the experiments on daylighting top in the hanging load of steel structure under the working condition of stable performance. Thus provides the daylighting top smooth acceptance of the premise. Through the above about the daylighting top of the key technology research, hoping for design and construction to provide certain reference and basis in the future.In practice, daylighting top also needs pay attention to the design and technical clarificaiton in place, blind spot check construction control, crossover operation, to join each other all the construction work. So for the daylighting top overall quality control and the requirements of the technical indicators can be implemented. Daylighting top key technology of the promotion,for the shorter construction cycle, the construction quality control has a wide range of practical significance and application value.
