一般建筑外墙窗的安装,按照常规施工方法,即在房屋结构至二层以上(窗过梁底模拆除后)便可进行外墙窗的安装工作,但在几十米乃至百米以上建筑物,要求外立面墙,竖向、横向为一直线,如用挂线锤方法显然不现实,如用经纬仪测出垂直线,虽然较精确,但一受地理位置之局限,二有外脚手之遮挡视线,困难亦很大。在上海亚洲宾馆施工中,我们采取了如下办法收到了较好的效果,其做法是:一、在每层楼面弹好墙身线的同时,沿墙身线平行方向,向内放500厘米即为外墙窗与外墙厚度位置的关系控制线,再弹出每间之中心线,或窗的中心线,即为外墙窗横向之控制线。
The installation of exterior wall windows for general building exterior wall windows can be carried out according to conventional construction methods, that is, after the housing structure is up to the second floor (after the window lining bottom mold is removed), but the installation of external wall windows can be carried out, but in tens of meters or even 100 meters or more For objects, the facade wall is required, and the vertical and horizontal directions are straight lines. If the method of using a hanging hammer is obviously unrealistic, such as using a theodolite to measure the vertical line, although it is more accurate, it is limited by the geographical location, and there are external feet. It is difficult for the hand to block the line of sight. In the construction of the Asian Hotel in Shanghai, we have taken the following measures and received good results. The approach is as follows: 1. While playing the wall line on each floor, put 500 centimeters inward along the parallel line of the wall line. That is, the control line for the relationship between the thickness of the external wall and the external wall, and then pop out the center line of each, or the center line of the window, that is, the horizontal control line of the external wall window.
