38、 、加强班前与班后的安全技术交底与检查工作，工作人员不准远离施工现场，防止意外事故发生。吊装时，未焊接牢固和未连接紧固的各种零部件不允许起吊作业。8、吊装时对构件的保护吊装时如不采用焊接吊耳，在构件本身用钢丝绳绑扎时对构件及钢丝绳进行保护：（1） 、在构件四角做包角（用半圆钢管内夹角钢）以防止钢丝绳刻断。护角示意图（2） 、在绑扎点处为防止 H 形钢梁局部挤压破坏，临时加一块加强胫板。四、吊装方法1、钢柱的吊装（1）柱吊装前准备重选车间 B-C 跨钢结构吊装专项施工方案7待现场检验合格后，即检查预埋铁板、预埋螺栓的轴线、平整度、标高，预埋铁板标高根据测设在厂房原有柱子上的+6.000m 标高用

39、钢尺测量并复查。预埋铁板待检查、测量合格后，检查其他项目。柱吊装前再次检查柱的各种基准点、中心线、吊（捆扎）点以及表面是否有损坏和污垢，确认无误后开始捆扎和吊装。钢柱吊装前，应先将柱脚螺栓表面清理干净。为消除立柱长度制造误差对立柱标高的影响，吊装前，从立柱顶端向下量出理论标高为 1m 的截面，并作一明显标记，便于校正立柱标高时使用。在立柱下底板上表面，做通过立柱中心的纵横轴十字交叉线。吊装前复核钢丝绳、吊具强度并检查有无缺陷和安全隐患。（2） 、吊点的选择本工程全部为钢柱，弹性较好，因此吊点采用一点起吊，吊耳放置在柱顶处，柱身垂直、易于对线校正。（3） 、起吊方法本工程采用 QY16 型汽车吊

40、进行吊装，由专人指挥。考虑到场地狭窄的主要原因，本次吊装钢柱采用对起重设备机动性能要求较低的滑行法，吊装时在柱子滑行范围内铺设层板，防止损伤新浇筑好的楼面。过程主要包括绑扎 起吊对位 临时固定 校正最后固定。吊装前准备工作就绪后，首先进行试吊，吊起一端高度为 100200时停吊，检查索具牢固性和吊车稳定性以及钢柱的垂直度，然后指挥吊车缓慢下降，用两台经纬仪沿中心轴线成 90 度choose the correct meaning; (4) to correct the typos; (5) so the child write words (ABAB, and AABB); (6) in ac
