Construction Technology for Waterproofing Structure of"Hui"-shaped External Wall Columns and Curtain Wall Windows in Residential Buildings
This article mainly explores the construction method of the waterproof structure of the"U-shaped"exterior wall columns and curtain wall windows in a residential building.In the construction of the"Hui"shaped exterior wall column,innovative use of graphite polystyrene board instead of internal formwork has been made,eliminating the need for formwork support and improving the insulation performance of the exterior wall.During construction,the focus is on strengthening the technical control of pre embedded wall column steel bars,pasting graphite polystyrene boards,binding steel cages and pre embedded steel bars,and concrete pouring and curing.In the waterproofing construction of exterior windows of curtain walls,the method of adding waterproof steel plates is adopted to seal the gap between the window frame and the wall structure,thereby improving the waterproofing performance.Install bottom,side,and top waterstop steel plates in ascending order,and leave a 2%slope at the bottom and top for easy drainage.The edge of the waterproof steel plate is filled with sealant to improve the waterproof effect.
