Huadian Project in Karamay Xinjiang

The steel structure of this project adopts a bolted ball grid structure, with a coal shed span of 85m and a length of 286m. Four corner cone bolt ball node form, internal chord support of the grid, welded ball support for the grid, closed mountain walls at both ends, and single-layer color steel plate for the roof; The support of the grid frame is a hinge point, supported on reinforced concrete columns. The top elevation of the vertical wall concrete column is 2.5m, and the top elevation of the mountain wall concrete column in this project is 1.5m. The steel roof structure adopts a positive four corner cone welded ball node grid structure with an elliptical hyperbolic shape, with a long axis of 130.42 meters and a short axis of 98.944 meters. The steel grid support columns are concrete columns connected by finished seismic ball joint bearings. The elevation of the stand side bearings is 13.95 meters, the elevation of the long axis end bearings is 6.75 meters, and the maximum span between bearings is 93.38 meters. The maximum thickness of the grid structure is 6.5 meters. The highest point of the grid structure has an elevation of 21.35 meters.
