屋顶风机安装施工方案

1、屋顶风机安装施工方案1、编制说明* 车间厂房屋顶设置屋顶风机84 台，分别布置在厂房屋顶上，风机单体最大重量为188Kg,无法用汽车吊直接吊装就位，人工搬运也比较困难，因此需要考虑采用特殊的工装措施进行屋顶风机的就位。在安装的过程中，屋面瓦容易损坏，需要采取防护措施，故编制该专项方案，明确施工顺序以及防护措施措施。2、工程概述该厂房屋顶风机共有84台，其中76台为体积较大，长X宽X高,1200 X1200X 1250mm单体重量为188Kg,分别布置在 AB跨、BC跨、EF跨和FG跨，每跨19台；另外8台体积重量较小，长X宽X高，750 X750X 800mm布置在GH夸，每台风机配有一台止回

2、阀。3、风机安装方法及技术措施由于屋顶风机单体重量为188Kg,人工无法直接搬运，汽车吊也无法直接吊装就位，因此我方决定制作一套特殊工装措施进行屋顶风机的安装就位。主要方法为在屋顶风机口边厂房通长方向上用槽钢和角钢制作滑道，在滑道上安装小车，将屋顶风机通过小车运输到安装位置，再进行就位。在滑道与屋面瓦接触的部位垫上橡胶垫，保护屋面瓦。4 、具体安装步骤4.1 止回阀安装每台屋顶风机都配有一台止回阀，止回阀有两种规格尺寸，一种规格为：长X宽X高，900 X 900X 60mm此种规格有76台；另一种规格：长X宽X高,500 X 500X 60mm止匕种规格有 8台。止回阀供货时没有考虑到现场的安
