大型钢螺旋楼梯的计算和装修过程分析

Calculation of Large-sized Steel Screwy Stairs and Analysis of their Decoration Order

大型钢螺旋楼梯在荷载作用下,楼梯整体存在一定的扭曲,内外圈梯梁对支座的作用也和普通楼梯不同。由于钢结构刚度较小,内外圈梯梁变形都较大,而且变形差异较大,对后期的装修带来较大的影响。所以选择合理的施工装修顺序对保证装修质量至关重要。

Architects and Civil Engineers are now more and more favor of steel screwy stairs because of their mellow lineafion and portable patterns. Large-sized steel screwy stairs are different with small ones at their beating and distortion performance. With loads＇ effect, large-sized stairs will be twisted, and the act to supports will be different with normal-sized stairs. Steel stairs have large displacement due to their poor stiffness. The displacement of inner and outer beams varies a lot, and it will affect the decoration construction, so a reasonable decoration construction sequence is necessary.
