6.2.3钢构件分段计划与吊耳设置（改）17页.doc

三 钢结构分段与吊耳设置1 构件分段原则分段原则见下表：序 号构件种类构件简单描述分段原则1主杆件主杆件采用焊接圆钢管，直径在700㎜～1400㎜，壁厚随内力大小变化，在12mm～140mm之间材质主要为Q390B，部分铸钢管材质为LX420；根据施工方案及结构特点，在运输许可的条件下，尽可能将主杆件长度分长，分段位置选择在主次杆件连接节点附近 2次杆件次杆件采用焊接箱形梁，高度为450mm～600mm，宽度为150mm～300mm，壁厚随内力大小变化，在10mm～30mm之间材质为Q345B；根据吊车起重量及结构特点：主杆件设置“米”字节点和主杆件设次杆件连接牛腿的原则分段， 现场分片组装拼接节点处均设置安装临时连接板，以便现场分片拼装对接3节点主节点采用铸钢节点按设计要求进行分段，超过工厂铸造限制的节点两段铸造，现场拼接分段示意图： 2主杆件分段示意3次杆件分段示意2 临时连接板与吊耳的设置类型详图设置位置铸钢节点与立面竖杆件的起端连板耳板距离构件端口70mm 肩谷节点： 40mm厚Q345钢板其余节点或竖杆件： 40mm厚Q345钢板主杆件连接端连板耳板距离构件端口70mm。

连接耳板：-20×250×90mm 材质Q345B主杆件吊耳吊耳位于梁两端，与梁端点距离为1/4梁长8～15t构件吊耳： -25×200×110mm 材质Q345B15～35t构件吊耳：-40×200×110mm 材质Q345B次杆件吊耳位于梁两端，与梁端点距离为1/4梁长20×130×90mm 材质Q345B连接夹板-14×740×90mm 材质Q345B3 典型单元结构面构件的分段与相关参数3.1 典型单元的结构面组成3.2 单元结构面各构件分段与相关参数见下表：M1结构面的构件分段及参数表编 号分段长（m）吊装重量（t）离内环点距离（m）离支座面高度（m）1D-1A2.01．8319．2441A2.01.8034.920A2.01.8034.9E20A-G11-1-110.22.534.637E20A-G11-1-212.82.8613.439E1A-G11-1-112.32.6413.840E1A-G11-1-210.62.585.237E1D1A-G14-113.29．50034.9E1D1A-G14-213．2159．51034.9JG1-1-15.20.332.335.3JG1-1-25.20.332.335.3JG1-1-35.20.332.335.3JG1-1-45.20.332.335.3JG1-1-55.20.332.335.3JG1-1-65.20.332.335.3JG1-1-75.20.332.335.3JG-1-1-85.20.337.237.6JG-1-1-95.20.337.237.6JG-1-1-105.20.337.237.6JG-1-1-115.20.337.237.6JG-1-1-125.20.337.237.6HG1-1-113.91.324.835.9HG1-1-28.50.774.835.9HG-1-1-314.81.329.737.6HG-1-1-46.90.614.239.5M2结构面构件分段及参数表编 号分段长（m）吊装重量（t）离内环点距离（m）离支座面高度（m）2A2.01.8034.91A-2A2.01．8319．244E1A-G11-2-112.82.8613.439E1A-G11-2-211.52.564.637E2A-G11-1-114.23.1714.140.2E2A-G11-1-212.32.7465.739E1A2A-G14-113.29.24034.9E1A2A-G14-211.68.16034.9JG1-2-15.20.332.335.3JG1-2-2 5．00.322.335.3JG1-2-35.20.332.335.3JG1-2-45.00.322.335.3JG1-2-55.20.332.335.3JG1-2-65.00.322.335.3JG1-2-75.20.332.335.3JG-1-2-85.00.327.237.6JG-1-2-95.20.337.237.6JG-1-2-105.00.327.237.6JG-1-2-115.20.337.237.6JG-1-2-125.00.327.237.6HG1-2-1141.23 4.8 35.9HG1-2-27.960.694.835.9HG-1-2-314.41.269.737.6HG-1-2-46.70.5314.239.5M3结构面的构件分段及参数表编 号分段长（m）吊装重量（t）离内环点距离（m）离支座面高度（m）1A1.9514.620.233.3E1A-G-9-1-114.54.3119.439.1E1A-G9-1-22.81.119.640.2E1A-G10-14.21.317.740.3 E1A-G10-214.54.498.937.0JG1-3-14.020.2817.241.4JG1-3-25.60.3517.240.6JG1-3-34.020.2817.238.7JG1-3-45.60.3517.237.4JG1-3-54.020.2817.236.1JG1-3-65.60.3517.234.7JG1-3-74.020.2812.138.9JG-1-3-85.60.3512.137.7JG-1-3-94.020.2812.136.4JG-1-3-105.60.3512.135.3JG-1-3-114.020.287.436.9JG-1-3-125.60.357.435.7HG1-3-14.021.0914.637.8HG1-3-29.10.739.936.8HG-1-3-314.10.284.935.7M4结构面的构件分段及参数表编 号分段长（m）吊装重量（t）离内环点距离（m）离支座面高度（m）E1A-G-9-2-114.54.3119.439.1E1A-G9-2-2 3.2 1.119.640.2JG1-4-14.020.2817.241.4JG1-4-25.20.3317.240.6JG1-4-34.020.2817.238.7JG1-4-45.20.3317.237.4JG1-4-54.020.2817.236.1JG1-4-65.20.3317.234.7JG1-4-74.020.2812.138.9JG-1-4-85.20.3312.137.7JG-1-4-94.020.2812.136.4JG-1-4-105.20.3312.135.3JG-1-4-114.020.287.436.9JG-1-4-125.20.337.435.7HG1-4-14.021.0914.637.8HG1-4-29.10.739.936.8HG-1-4-314.10.284.935.7M5结构面的构件分段及参数表编 号分段长（m）吊装重量（t）离内环点距离（m）离支座面高度（m）1D1A3.259068.230.7E1D1A-G12G-1-112.80.6224.142.9E1D1A-G12G-1-212.80.6235.338.9E1D1A-G12G-1-39.10.44446.435.6E1D1A-G12G-1-49.65.26.132.6E1A-G8-1-11211.456.431.08E1A-G8-1-21211.446.131.7E1A-G8-1-3109.536.232.3E1A-G8-1-49.621.624.833.1JG2-5-1111.7625.340.7JG1-5-210.091.6125.339.2JG2-5-3111.7625.338.3JG2-5-410.091.6125.336.9JG2-5-5111.7625.335.4JG2-5-610.091.6125.334.0JG2-5-7111.7636.337.5JG-2-5-810.091.6136.336.0JG-2-5-9111.7636.334.9JG-2-5-10 10.091.6136.333.4JG-2-5-11111.7647.734.9JG-2-5-1210.091.6147.733.4HG2-5-114.12.2630.836.6HG2-5-27.61.2242.134.8HG-2-5-33.30.5353.332.7M6结构面的构件分段及参数表编 号分段长（m）吊装重量（t）离内环点距离（m）离支座面高度（m）E1A2A-G12G-1-112.40.6024.142.9E1A2A-G12G-1-212.40.6035.338.9E1A2A-G12G-1-38.00.38746.435.6E。
