一、钢结构工程施工过程中的部分问题及解决方法

1、构件的生产制作问题

措施:钢结构施工单位协同土建施工单位一起完成预埋件工作,混凝土浇捣之前必须复核相关尺寸及固定牢固。

(2)MAOSHUANBUCHUIZHIXIANXIANG:KUANGJIAZHUZHUJIAODIBANSHUIPINGDUCHA,MAOSHUANBUCHUIZHI,JICHUSHIGONGHOUYUMAIMAOSHUANSHUIPINGWUCHAPIANDA。ZHUZIANZHUANGHOUBUZAIYITIAOZHIXIANSHANG,DONGDAOXIWAI,SHIFANGWUWAIGUANHENNANKAN,JIGANGZHUANZHUANGDAILAIWUCHA,JIEGOUSHOULISHOUDAOYINGXIANG,BUFUHESHIGONGYANSHOUGUIFANYAOQIU。

措施:锚栓安装应坚持先将底板用下部调整螺栓调平,再用无收缩砂浆二次灌浆填实,国外采用此法施工。锚栓施工时,可采用粗钢筋或者角钢等固定锚栓,焊成笼状,完善支撑,或采取其他有效措施,避免浇灌基础混凝土时锚栓移位。

(3)MAOSHUANLIANJIEWENTIXIANXIANG:ZHUJIAOMAOSHUANWEININGJIN,DIANBANWEIYUDIBANHANJIE;BUFENWEILU2~3GESIKOUDEMAOSHUAN。

措施:应采取焊接锚杆与螺帽;在化学锚栓外部,应加厚防火涂料与隔热处理,以防失火时影响锚固性能;应补测基础沉降观测资料。

3、连接问题
