1985年11月中旬至1986年2月初,我们采用综合蓄热电暖器养护法完成了北京国际饭店主楼19～24(A)层七个楼层的结构施工。完成结构工程建筑面积16870m~2,现浇混凝土量6163m~3,其中墙体混凝土3140m~3,楼板混凝土3023m~3。为60～80m高空冬期滑模施工提供了经验。一、工程概况国际饭店主楼建筑面积7.17万m~2,平面呈蝶形(图1),共34层(包括三层地下室,两层设备层),土0.00以上高度104.40m,结构形式为筒体剪力墙暗框架体系,墙及楼板全部为现浇300号钢筋混凝土。墙体采用
From mid-November 1985 to early-February 1986, we completed the structural construction of seven floors of floors 19 to 24 (A) of the main building of the Beijing International Hotel using the integrated heat storage heater conservation method. The construction area of the structural engineering is 16870m~2, and the amount of cast-in-place concrete is 6163m~3, among which the wall concrete is 3140m~3 and the floor concrete is 3023m~3. For the 60 ~ 80m high altitude winter slipform construction experience. I. Project Overview The international hotel main building has a building area of 71,700 m2, and the plane is butterfly-shaped (Figure 1). There are 34 floors (including three basements and two equipment floors), and the soil is more than 0.00 and the height is 104.40m. The structure is cylindrical. The body shear wall dark frame system, walls and floor slabs are cast-in-place No. 300 reinforced concrete. Wall use
