1999年度国家科技进步奖日前揭晓,由上海建工集团独家承担和实施的“超高层建筑施工技术研究—金茂大厦88层”科技以其8个方面的优异成果,荣获一等奖。 该工程的平面为八边形对称的巨型混凝土建筑体,其垂直累积误差必须控制在5厘米之内。要求模板体系和吊装控制设备要有良好的性能和严格的精度。在主体建筑100米、200米和300米处配置了道高8米的巨型外伸钢桁架,用于1.8万吨重的钢结构安装的高强螺栓共400吨,计42万套,要求将重达20吨的单个构件在高空吊装连成整体,并丝毫不差以保证每只螺栓孔畅通。这种新颖的超高层建筑结构形式,给施工带来极大的难题,就是模板脚手体系要在100米、200米和300米高处进行空中解体和组装,高空中 1999 National Science and Technology Progress Award has been announced recently, by the Shanghai Construction Engineering Group exclusive commitment and implementation of “super high-rise building construction technology research - Jinmao Tower 88” science and technology for its eight outstanding achievements, won the first prize. The project’s plane is octagonal symmetrical giant concrete buildings, the vertical cumulative error must be controlled within 5 cm. Requirements template system and lifting control equipment to have good performance and strict accuracy. In the main building of 100 meters, 200 meters and 300 meters at the allocation of 8 meters high giant steel truss extension for 18,000 tons of steel structure installation of high strength bolts a total of 400 tons, totaling 420,000 sets, will require the weight Up to 20 tons of individual components in the high-altitude hoisting even into the whole, and not bad in every way to ensure that each bolt hole smooth. This novel form of high-rise building structure, to the construction of a great problem is that the template scaffolding system to be 100 meters, 200 meters and 300 meters high for air disintegration and assembly, high altitude
