Report from our correspondent (reporter Han Ling) recently, Chaofeng steel signed the new Hangzhou train station project roofing system second section of project, it also inherits the built the project main body steel structure engineering and roof steel structure engineering, and obtain a sub project, the contract of about 40000000.
New signing for new Hangzhou East Railway Station east station building engineering project bid second (P-U axis) project is about 262.599 meters long, width of about 142.78 meters, an area of about 40000 square meters. The roof with standing seam aluminium magnesium manganese alloy roof panel, metal roof area of about 37494 square meters, of which the metal roof panels up to 262 meters, the highest point of elevation of about 40 meters in the center. In addition to the metal roofing, part of the roof is provided with roof skylight to increase roof lighting conditions, using hollow toughened glass skylight group box.
In 2010 October, Chaofeng steel structure to undertake a new Hangzhou train station N axis to U axis parts, including basement, elevated, elevated dissection steel structure project of about 20000 tons; in 2011 September, and undertake the station roof steel structure project, the total amount of steel of about 6100 tons, covering an area of 4 square meters. The complex engineering structures, especially for large diameter conical tube column, special-shaped frame column used in domestic construction steel structure is extremely rare, with design difficult, difficult processing, difficult positioning, assembling, hoisting difficult difficult, group design institute, technology department, production department, project department the close cooperation, a crack problem, especially the development of large diameter oblique elliptic cone pipe production technology, for the smooth implementation of Hangzhou train station project has played a key role, at the same time, the technology has obtained national patent for utility model.
