单层厂房预制钢筋混凝土结构安装单层厂房预制钢筋混凝土结构安装installation of singlelayer precast reinforced concrete structure for workshop building
daneeng ehangfong yuzhi gangjinhunningtu JiegouanZhuang单层厂房预制钢筋混凝土结构安装(instal-lation of sidglelayer preeast reinforeed eon-eretestrueture for workshoP building)按设计与施工规范要求，将单层钢筋混凝土结构厂房的构件安装、固定到设计位置上的施工作业。构件组成包括柱、吊车梁、预应力析架(屋架及托架)和屋面板。由于构件单件较重，在受到撞击或不正常外力时易发生裂缝或断裂性损坏，因而安装时需合理地选择吊点，使用吊梁，保持起吊平稳，防止构件(特别是析架)发生抖动;禁止不正常施加外力(拉力、扭力等)强行搬转和矫正。安装方式通常分为单件流水作业和综合作业两种。前者是沿厂房全长先将柱列系统构件安装好，然后安装吊车梁，再安装屋盖系统构件;后者是将某一线的柱、梁、屋盖系统构件全部安装固定后，再安装下一线。在冶金工厂施工中多采用单件流水作业。在单层多跨钢筋混凝土结构厂房安装中，应确定中间部位一个净空较高、跨度较大的跨作为基准跨，该跨安装进度应比邻跨超前2~3线，以利合理地分配误差，避免公差积累。
安装准备除按一般厂房结构安装所要求进行的各项准备外，还应做好下列工作:(1)混凝土柱一般均在现场预制，预制场地需进行夯实，防止地基不均匀下沉而造成构件损坏。(2)析架组立、张拉及灌浆养护条件的准备。(3)拓架起吊平面外刚度的核算及必要的加固措施。(4)朽架吊点、吊梁及索具的选定。(5)预制柱翻转900，以增加柱在起吊时的抗弯能力。(6)析架间距调整器具的设计。
钢筋’混凝土柱的安装柱的起吊有旋转法(起重臂杆绕柱脚旋转而逐渐吊起的操作法)和滑行法(起重臂杆不旋转只提升吊钩的操作法)两种。柱的吊点一般设在牛腿下部。吊装时，按柱身离地面的竖直情况，分为垂直吊法和斜吊法石在起重机起重能力允许的情况下，应优先采用垂直吊法。采取斜吊法时，应用卷扬机和滑轮组拉住柱脚，用辅助主机将柱吊运至杯口。当柱重超过主机起重能力时，可采用双机抬吊。一般在柱子吊点处设有吊装孔，配备专门吊具(吊装轴)进行吊装。不设吊装孔的柱可用绳索直接绑扎吊装，但需采取保护柱棱角的措施，以防柱损伤。柱插入杯口后，应用缆绳及钢楔初步找正、固定，然后用经纬仪在柱相邻的两侧复测柱的垂直度，并量测牛腿的平面标高，确认合格后即可进行永久固定。
重型钢筋混凝土柱常采取分节吊装、高空组接的方法(上、下节柱的钢筋对焊或柱外壁连接板对焊)。
