近几年来,我们在工程施工实践中积累一些改进建筑物外墙变形缝的新作法,取得了较好的效果。现将具体作法介绍如下。一、外墙变形缝新旧两种作法比较目前处理外墙变形缝都是用26号镀锌铁皮加工制作并通过墙体中的预埋木砖固定在墙上。实践证明,这种作法存在较多缺陷。首先 In recent years, we have accumulated a number of new practices for improving the deformation joints in the external walls of buildings in the construction practice and achieved good results. The specific practices are described below. First, the new deformation of the outer wall of the old and the new two methods to deal with the current deal with the deformation joints of the outer wall are processed with 26 galvanized iron sheet and through the wall in the embedded wooden bricks fixed to the wall. Practice has proved that this practice has many flaws. First of all
