管道穿楼板


工艺流程
(1)套管预留洞做法(适用于无水部位)
套管制作→放线定位→预留洞口→管道与套管安装→套管固定→套管外封堵→套管内封堵→套管刷漆    
(2)套管预埋做法(适用于有水或无水部位)

套管制作→放线定位→套管预埋→套管清理→管道安装→套管内封堵→套管刷漆

施工要点



(1)套管制作:按管道规格及所穿楼板的厚度切割套管,套管比立管大1~2个管号,套管与管道之间的间隙20~30mm为宜,套管高出无水楼面装饰面层20mm,高出有水楼面装饰面层应为50mm,有水楼面的钢套管应采用防水套管。
(2)洞口预留、套管预埋:预留洞口时,洞口宜为圆形,洞口直径比套管大50mm~100mm;采用吊通线的方式确定预埋套管位置。
(3)管道安装:调整管道与套管的同心度,立管垂直度偏差控制在2mm/m且5米以上垂直度偏差≤8mm。
(4)套管封堵:套管外封堵采用与楼板同强度等级微膨胀细石混凝土分两次封堵并试水检验;套管与管道之间的缝隙用石棉水泥封堵严密,并在上下口各留20mm深的凹槽,在上下口凹槽内嵌填密封胶密封,密封胶要求与套管端面平齐,胶缝要求均匀。
(5)套管与管道之间的空隙应均匀,高出楼地面的高度应一致,板面上外露套管刷黑色或灰色油漆。
(6)创优工程的楼板下套管底部安装装饰圈。

(7)当管道为PVC管,并且设计有阻火圈时,底部应加阻火圈。

施工要点



(1)刚性防水套管制作参见02S404-JS10-1防水套管。
(2)采用吊通线的方式确定预埋套管位置,套管两端用胶布等密封,避免堵塞,保证套管周围混凝土密实。当管道穿越的屋面为普通屋面:穿上人屋面透气管套管高出屋面完成面高度h=800mm,穿屋面给排水管套管高出屋面完成面h=300mm;当管道穿越的屋面为覆土(种植)屋面时,穿屋面透气管套管高出覆土(种植面)高度h=800mm,穿屋面给排水管套管高出覆土(种植面)高度h=300mm。
(3)立管垂直度偏差控制在2mm/m且5米以上垂直度偏差≤8mm。
(4)套管与管道之间的缝隙用石棉水泥封堵严密,在上部收口处嵌填密封膏,表面光滑。
(5)防水层必须沿套管上返不少于300mm高。
(6)在套管周边浇筑混凝土保护墩,高度为300mm。

(7)创优工程的屋面下套管底部安装装饰圈。

套管穿有水部位墙体示意图



施工要点



(1)套管制作:有水部位的套管按设计要求选用刚性防水套管或柔性防水套管,刚性防水套管及柔性防水套管制作参见02S404-JS10-1、02S404-JS10-2。套管比管道大1~2个管号,两端与装饰墙面平齐。
(2)砌体套管安装:将套管套入管道并安放于各个洞口处,用木楔临时固定,使套管与管道同心,套管与墙面平齐,套管与管道之间的间隙用石棉水泥填塞密实,表面光滑平整。
(3)混凝土墙套管预埋:结构施工时按图测量定位套管坐标、位置,预埋套管,套管两端用胶布等密封,避免堵塞。
(4)套管封堵:套管与管道之间的缝隙用石棉水泥封堵严密。

(5)创优工程装饰圈安装:装饰圈的宽度与管道的直径相匹配,DN100以下装饰圈宽20mm,DN100~DN150以内装饰圈宽30mm。对于非防火墙可用3mm橡胶板制作,有防火要求的应采用阻燃PVC板制作。
