住宅楼梯间是单元住户共用的地方。《住宅建筑设计规范》对楼梯间的采光和通风等都有明确的要求,可是,在规范及实际设计中却常常忽略了平台防、排雨水的问题。在雨水较多的地区,在风雨交加时常出现平台积水,且顺着踏步、楼梯井向下流,影响人们的行走;特别对老人与儿童,更加不便。笔者根据一些住宅楼梯间的现状,提出以下改进意见,供设计时参考。 Residential stairwells are shared by apartment occupants. The “Code for Design of Residential Buildings” has clear requirements for lighting and ventilation in stairwells. However, in the specification and practical design, the problem of platform prevention and drainage is often overlooked. In areas where there is a lot of rain, platforms often accumulate water during rain and rain, and they follow the steps and down the stairs to affect people’s walking. This is particularly inconvenient for the elderly and children. According to the status quo of some residential stairwells, the author proposes the following improvements for reference during design.
