我们在实践中摸索出一种现场制作安装钢管旋转楼梯栏杆的方法,简单易行、工效高、质量完全符合设计要求。现介绍如下: 1.根据旋转楼梯栏杆的长短和需要,用8mm厚的钢板制作一简易平板工作台。在工作台上用槽钢头、扁钢头、小钢板等角料焊接成小于旋转楼梯栏杆设计直径1/4的圆弧模槽(图1)。 In practice, we have developed a method of on-site production and installation of steel pipe spiral staircase railings, which is simple and easy to implement, high work efficiency, and quality in full compliance with the design requirements. The introduction is as follows: 1. According to the length and needs of the rotating staircase railings, a simple flat table is made from 8mm thick steel plate. On the workbench, the arc angle head, flat steel head, small steel plate and other angle materials are welded into an arc-shaped groove less than 1/4 of the diameter of the rotating stair railing (Fig. 1).
