汽机扩建端山墙属于临时性围护结构,要求使用灵活,拆迁方便,因此,一般都采用钢骨架,轻型墙板。旧式扩建端山墙(以牡二电厂一期工程汽机临时端山墙为例)的结构是:设置山墙柱基础(钢筋混凝土独立基础),其上安装钢柱(工~#45),钢柱顶部与钢屋架铰结,钢柱间设若干道横梁(工~#30)并有剪刀撑((?)~#20),8米以下墙板为砖墙、8米以土墙板为双 The extension gable of steam turbines is a temporary enclosure structure, requiring flexible use and convenient demolition. Therefore, steel skeletons and light wall panels are generally used. The structure of the old-style extension end gable (an example of the temporary end girder of the first phase of the first-phase project of Mu’er Power Plant) is as follows: gable base (reinforced concrete foundation) is installed, and the steel column (working-#45) is installed on the top of the steel column. Steel truss hinge joints, a number of beams between steel columns (working ~ # 30) and scissors ((?) ~ # 20), 8 meters below the wall for the brick wall, 8 meters to the wall for double
