我院在设计湘江氮肥厂尿素车间蒸发分解平台的工程中,采用了梁板式升板结构。 一、结构 蒸发分解平台二期工程为三层梁板式升板结构,柱距5米,跨度6.5米,层高5米,升板面积每层为153平方米。 楼面设计荷载。静载:一层为30.3吨,二层为26.6吨,三层为30吨。均布活荷载均为300公斤/平方米,超载系数取1.2。 采用捣制钢筋混凝土杯形基础,人工砂垫层地基(因原地基为较深的回填土),钢
In the project of designing the evaporative decomposition platform of the urea plant of the Xiangjiang Nitrogen Fertilizer Plant in our institute, a beam-plate lift structure was adopted. I. Structure The second phase of the evaporation decomposition platform is a three-story beam-type riser structure. The column spacing is 5 meters, the span is 6.5 meters, the height is 5 meters, and the riser area is 153 square meters per floor. Floor design loads. Static load: 30.3 tons for the first floor, 26.6 tons for the second floor, and 30 tons for the third floor. The average live load is 300 kg/m2 and the overload coefficient is 1.2. Using a reinforced concrete cup base made of tantalum, artificial sand cushion foundation (because the original foundation is a deeper backfill), steel
