为彻底根治预制垃圾道板接头处的横向裂缝,我们对传统作法进行如下改进。1.预制垃圾道板时,将每层的垃圾道板做成一块,竖向安装,使层与层间垃圾板接缝位置正好位于每层的休息平台处,因为垃圾道板中间不存在接头,也就从根本上杜绝了裂缝的出现。2.采用此法施工预制件的运输不太方便。为解决这个问题,我们采用了随层预制的方法。也就是说,哪一层用的垃圾道板就在哪一层预制。3.待主体施工完毕和楼梯扶手施工前,即进行
In order to completely eradicate the horizontal cracks in the prefabricated landrafts joints, we make the following improvements to the traditional methods. 1. When prefabricating the garbage road boards, make the garbage road boards of each floor into one piece and install them vertically so that the seams between the layers and the floors are located at the rest platform of each floor, because there is no joint in the middle of the garbage road boards , Also fundamentally put an end to the emergence of cracks. 2. The use of this method of construction of prefabricated transport is not easy. To solve this problem, we adopted a method of prefabrication with layers. In other words, which layer of rubbish plywood is prefabricated. 3. Until the main construction is completed and the staircase handrail construction, that is
