我市近十年来大量兴建的高层剪力墙结构体系、各项技术经济指标均比较先进、因此得到广泛推广,并且在今后一个时期中还将继续采用。目前各施工部门在这类建筑的主体结构施工方法上基本相同,主要程序为:“浇注墙体砼”→“安装楼板”→“补浇板缝砼”→浇上层墙体砼”的层层往复工艺。笔者从很多工地看到,其中“补浇板缝砼”工序有如下一些普遍现象,即:(1)板缝下部砼有蜂窝麻面,不密实。(2)补浇砼时大量砂浆流失。(3)当上部积水、水即从板缝
The high-rise shear wall structural system and various technical and economic indicators that the city has built in large quantities in the past ten years are relatively advanced and are therefore widely promoted, and will continue to be adopted in the coming period. At present, each construction department is basically the same in the construction method of the main structure of this kind of building. The main procedure is: “pour wall rakes” → “install the floor slabs” → “filling slab rakes” → pour the upper wall ridges Reciprocating process.The author sees from many construction sites, among which the following procedures are commonly used in the process of “recoiling slabs”, namely: (1) There are honeycomb pockmarks on the lower part of the seams, which are not dense. Loss of mortar (3) When the upper part of the water, water that is from the board seam
