钢结构箱形旋转楼梯制作技术

The Manufacturing Technology of Steel Structure Box-Type Revolving Stairs

在钢结构箱形旋转楼梯的生产制作过程中,先对图纸进行分析,建立BIM三维实体模型,在实体模型上找出尺寸控制点,绘制胎具放样图,搭设旋转楼梯专用组焊胎具,同时使用基于PKPM系统下的学思软件进行排版,通过对旋转楼梯生产过程中的下料尺寸、坡口角度、装配精度和焊接参数等对产品质量有着关键影响的因素进行严格控制,有效保证了钢结构箱形旋转楼梯的制作质量。

In the production process of steel structure box type rotary staircase,first analyze the drawings,establish the BIM 3 d entity model,find out the size control point on the entity model,tire lofting diagram,set rotating staircase special welding tools,using learning software based on PKPM system layout,through the rotating staircase production size,groove angle,assembly accuracy and welding parameters have key factors on the product quality of strict control,effectively ensure the production quality of steel structure box type rotary stair.
