A Discussion on the Type Selection of the 200 m Span Closed Coal Shed in the Thermal Power Plant

This thesis discusses the type selection of the concrete implementation of the 200 m span closed coal shed in the thermal power plant. We analyze the characteristics and development situations of five schemes for selection, and focus on introducing and recommending the closed coal shed which uses the PVDF membrane material as its outer space cover. Then we choose the steel grid of three-centered circulars and the membrane framework as its structure selection, and strives to make it highly coordinated with the surrounding buildings and environment. Such renovation is to turn it into an industrial construction in the new era with both aesthetics and practicality, and to promote the rapid development of the membrane material structure as a new product of new technology. At the same time, the paper provides guidance and reference for the type selection of the supramaximal span structure of 200 m and above. (paper)
