26、iyof wl. Hisoryha5965 kN/m。25t汽车吊其基本臂长16.5m ,最大臂长61m。最大基本臂 最大起重力矩为9526 kN/m ,最大最长主臂最大起重力矩为4675 kN/m。本标段所架设最大梁长为21.5m空心板梁，最大粱重为37.2t。吊装就位时，作业半径最大为8m,最大起重重量为48.9t, 起重机完全符合要求。2、起吊钢丝绳的选用根据所选钢丝绳为66mm, 67+1验算：最大起吊重量 37.2t,设起吊点二个，采用二根钢丝绳作业，每个吊点钢丝绳 受力为25%,考虑吊点受力不均，现每个吊点钢丝绳受力按 35% 考虑，即 Fmax=37.2 M5%=13.02t=1

27、30.2kN。根据钢丝绳的计算要求，最小破断拉力总合=2270 kN X1.249 （钢丝绳为呢绒芯的系数）=2835KN 。安全系数：f=2835/130.2=21.77 >f=5,所选钢丝绳适用。3、运梁炮车为了减少吊车移位，配备四台运输空心板梁的炮车。 炮车选 用进口三菱车，型号为 FV414 ,马力440匹，主车三轴10胎， 后拖架车双联四轴16胎。五、施工程序和方法:5.1、 施工程序图5-1空心板梁架设施工工序图5.2、 吊装顺序、方法及措施1、吊装顺序从内边梁开始至外边梁进行吊装， 这样有利于施工方案完善 和提高安全系数。2、梁板梁场吊装及加固预制梁预制、压浆、封锚完成后，

28、采用两台50T汽车吊配合运梁平车在制梁区将空心板梁运至储梁场存放。空心板梁运输及吊装，采用两台50T汽车吊在储梁场纵横移梁至运梁平车上， 再由运梁平车将梁运送至安装现场，由吊车把梁移至需安装位置上。运梁平车分前后两组，每组平车的承载重量为20to为了运梁平车对梁体受力均匀，空心板梁放在平车上时，用固定式可调的钢支撑将梁支撑稳定。 运梁时，两组平车之间用与空心板梁 支点距离等长的钢丝绳连系作保险绳，保证运梁的安全性。空心 板梁装车后，必须采取稳固措施，然后把空心板梁固定牢固后才 能卸去钢丝绳。梁片起吊时注意起吊力与梁片该处的纵向中心一致， 避免起 吊过程中梁片因起吊而受到侧向力作用， 而引起梁片

29、弯绕。起吊 过程应缓慢进行，以便及时调整起吊力的作用方向。运梁车稳固措施如图5-2所示：3、空心板梁的运输空心板梁运输过程中，对经过的道路须进行检查， 保证路面 的宽度，弯道直径，上下坡度、确保运梁车安全平稳走行，保证空心板梁运输过程中的绝对安全。 空心板梁在运输中，要确保 空心板梁梁板的稳固，防止空心板梁倾覆。空心板梁运输时，与交警及城管进行联系，同时安排在晚上natona prseiy, natona evialzaion, t he ha ppi nes of Ie pe opl e Ciaimporant tfl ow is to klepCina Roa d, cay frwa d
