楼梯是建筑物上下交通的专用设施,一些建筑对楼梯的造型和使用要求越来越高,它不仅体现建筑内部空间组织的合理与交通的畅通,同时也是建筑内部装饰设施的重要标志之一。但在实际工程设计中,楼层装修构造层的厚度与楼梯构造层的厚度不同,结构设计者往往容易忽视,只按建筑设计施工图所标注的尺寸扣除楼梯构造层后进行结构尺寸的标注,而忽略了构造层施工后的使用效果。以常见的现浇水磨石构造层为例:楼层构造层一般为70mm(其中:面层30mm、垫层40mm),楼梯构造层为30mm,当结构设计忽视了两个构造层的
Stairs are special facilities for transportation of buildings. Some buildings require higher and higher requirements for the shape and use of stairs. It not only reflects the rational organization of internal space and the smooth flow of traffic, but also is one of the important signs of interior decoration facilities. However, in the actual engineering design, the thickness of the floor decoration structure layer is different from the thickness of the stair structure layer, and the structure designer is often easy to ignore. Only the dimensions marked by the architectural design drawing are used to deduct the stair structure and mark the structure size. Ignore the use effect of construction after construction. Take the common in-situ grindstone construction layer as an example: the floor structure layer is generally 70mm (including: surface layer 30mm, cushion layer 40mm), and the stair structure layer is 30mm, when the structural design ignores the two structural layers
