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)。
