错层式住宅结构问题探讨

DISCUSSION ON STRUCTURE OF STAGGERED FLOOR DWELLING

随着人们居住质量意识的提高 ,错层式住宅受到青睐 ,但错层部位的结构设计尚无相应的规范及标准约束 ,在已经建成的错层式住宅中 ,错层部位出现水平裂缝。本文结合工程实例 ,总结了这种砖混错层住宅在使用上的优点和结构设计上所存在的问题 ,并给出了在建筑设计和结构设计上所采取的措施 ,如使圈梁尽可能拉通 ,在有错层的墙体上使用防止墙体开裂的构造柱等。文中所举的错层式住宅自建成以来 ,结构稳定 ,收到良好的效果。

The staggered floor dwellings are getting more popular along with stronger sense of people in living quality.However,there are no appropriate standards for structure design of staggered floor section.The horizontal cracks have come into being in the staggered floor section of completed dwellings.This indicates that there are still some shortages in designing the staggered floor dwellings.This paper,based on the case of some projects,summarizes the advantages in application of such brick-concrete staggered floor dwellings and the problems existed in structure design.Furthermore,some measures taken in structure design are proposed,such as possibly building the closed ring beam and using the structural pillars preventing the wall from cracking.The completed staggered floor dwelling mentioned in this paper has been stable in its structure.Better results have been obtained.
