On February 18, then in the morning, silver lake chau butterfly project started the first pillar of steel hoisting, marked the steel structure engineering.

　　Project is located in nantong, jiangsu qidong HuiLong Town, government is key to build the future of the core - lake butterfly plate, the total area of 81900 square meters, planning a total construction area of 376000 square meters, of which the building area of 235000 square meters, construction area of 141000 square meters underground.

　　Project by two 239 - meter butterfly lake super-tall tower and podium and two layers of basement, 44 layer, the Middle East tower podium 4 layer, west tower 43 layer and 3 layer podium, steel amount exceeds ten thousand tons, tower height to refresh the city skyline, become a new landmark of qidong rise.

　　Steel structure project subject to strong column, and civil engineering to the crossover operation, especially complex beam node, add reinforced connection device is used in most of high steel structure installation requirements.

　　Podium girder of the banquet hall 35.5 meters long, can't use conventional mechanical lifting equipment, for the sake of the construction smoothly, USES the triangle bracket after the check calculation, main girder section when entering the banquet hall inside, welding through the chain installation.

Twin towers, each has a hyperbolic towers, crowns, and USES the design of curved continuous, in the bottom of the tower crown elevation 199 meters place, to gradually by a great crown, coherent whole, emphasize the tower crown and the identification of the whole project.
