3支、吊架安装
3,installationofhanger
(1)安装前的准备工作:
室内管道的支架,首先应根据设计要求定出固定支架和活动支架的位置,再按管道的标高,把同一水平水管段两端的支架位置画在墙或柱子上;要求有坡度的管道,应根据两点间的距离和坡度的大小,算出两点间的高度差,然后的两点间拉一条直线,按照支架的间距,再墙上或柱子上画出每个支架的位置;如果土建施工时已在墙上预留的预埋支架孔洞,或在钢筋混凝土构件上预埋了焊接支架和钢板,应检查预留孔洞或预埋钢板的标高及位置是否符合要求,预埋钢板上的沙浆或油漆应清除干净。

(2)支架安装的一般要求:
支架横梁应牢固地固定在墙、柱子或者其它结构物上,横梁长度方向应水平,顶面应与管子中心线平行;固定支架承受着内压力和反力,因此固定支架必须严格安装在设计规定的位置,并应使管子牢固地固定在支架上,在无补偿装置且有位移的直段上,不得安装一个以上的固定支架。

(3)支架的受力部件,如横梁、吊杆及螺栓等的规格应符合设计或标准图的规定。
(3)thestresscomponentssupport,suchasabeam,rodandboltspecificationsshouldmeettherequirementsofdesignanddrawing.
(4)支架安装应使管道中心偏离距离符合设计要求,一般管道的表面离墙和柱的表面的净距离不应小于60mm。

(6)支架的固定方法:
墙上有预留孔洞的,可将支架横梁埋入墙内,埋设前,应清除孔洞内的碎砖及灰尘,并用水将洞浇湿,埋入深度应符合设计要求或有关标准图的规定,填塞使用1:
3水泥沙浆,必须填密实饱满;钢筋混凝土构件上的支架,将支架焊接在预埋板上;在没有预留孔洞和预埋板的砖或混凝土的构件上,根据管道直径采用M10-M16膨胀螺栓安装支架。
管道安装时使用的临时支架应有明显的标志,不可与正式支架位置冲突,管道安装完毕应拆除。
