摘　　要：当建筑墙体两面均需要有饰面清水效果时,保温层只能设置在现浇墙体中部。而目前主流的墙体保温材料挤塑聚苯板密度小、强度低,在混凝土浇筑过程中易漂浮、移动,被混凝土、振动棒的冲击破坏,影响墙体表面清水混凝土观感。基于此,提出并应用了清水混凝土外墙保温中置一体浇筑技术,取得了良好的效果,值得推广。When both sides of the building wall need to present the effect of fair faced finishing,the insulation layer can only be set in the middle of the cast-in-place wall.At present,the mainstream wall insulation material,i.e.extruded polystyrene board has low density and low strength.It is easy to float and move during concrete pouring,and is damaged by the impact of concrete and vibrating rod,which affects the appearance of fair faced concrete on the wall surface.Based on this,an integrated pouring technology of middle insulation for fair faced concrete external wall is proposed and applied,which has achieved good results and is worthy of popularization.
