上海市新式里弄住宅典型悬挑阳台变形处置方案探讨

Discussion on Deformation Treatment Scheme of Typical Cantilevered Balcony in Shanghai New-style Lane Residences

上海市新式里弄住宅主要建造于20世纪20—30年代,总平面大部分采用横向联列型式,单户平面有单开间、双开间等,户内设有门厅、卧室、起居室、厨房等,部分卧室或起居室设有阳台。由于房屋建造年代久远、阳台使用荷载较大等原因,部分悬挑阳台出现了较明显的变形,影响正常使用及结构安全。文章以上海市某新式里弄住宅为例,调查了悬挑阳台的结构布置和构造,分析了阳台变形原因,提出处置方案,为解决同类问题方面提供了参考依据。

Shanghai new-style lane residences were mainly built in the 1920s and 1930s.Most of the general layouts were horizontal combined type,with single width and double width in the single-family plan.There were foyers,bedrooms,living rooms,kitchens and so on inside,and some bedrooms or living rooms had balconies.Obvious deformation occurred on some cantilevered balconies due to the age of residences and the high load of balconies,which affected the normal use and structural safety.Taking a Shanghai new-style lane residence as an example,this paper investigates the structural layout and construction of cantilevered balconies,analyzes the reason of balcony deformation,and puts forward the treatment scheme,which provides reference for solving similar problems.
