现在,应用最广的现浇建筑物外墙结构是多孔骨料混凝土单层墙和带预制保温夹层的重混凝土三层墙。轻混凝土单层墙体对多孔骨料的要求较高,水泥用量大,轻混凝土现浇结构的滑升施工工艺也还不够成熟。因此,这种墙体在建筑中的大量应用受到一定限制。带有预制保温层的三层墙体的缺点是沿墙体的截面不能形成一个整体,而且在保温层之间会形成混凝土夹层,致使墙面的保
Now, the most widely used cast-in-place building exterior wall structure is a porous aggregate concrete single wall and a heavy-concrete three-layered wall with a precast insulation sandwich. The light-concrete single-layer wall has higher requirements for porous aggregates, and the amount of cement is large, and the sliding construction technology of the cast-in-place structure of the light-weight concrete is also not mature enough. Therefore, the large number of applications of such walls in buildings is limited. The disadvantage of a three-layer wall with a prefabricated insulation layer is that the cross-section along the wall cannot form a whole, and a concrete sandwich is formed between the insulation layers, resulting in the preservation of the wall surface.
