在以煤及木材为燃料的地区,多层住宅的烟道都是按标准图集砌筑的。笔者曾在四川边区工作近20年,在设计多层住宅烟道时,均套用西南J501(设备、装修)中预制烟囱及砖砌烟囱,在施工及使用中存在不少弊端:设计理想化,施工接槎困难,由于净空断面狭小,内壁边砌边抹灰困难,往往造成多抹或漏抹,抹面粗糙,施工质量极差,且无法检查;使用不久,烟油、炭灰附在内壁,很快堵塞主附烟道,严重串烟,无法使用;一旦杂物掉入,无法清理。
In areas where coal and wood are used as fuel, the flue of multi-storey houses is built according to a standard atlas. I have worked in the Sichuan Border Region for nearly 20 years. When designing multi-storey residential smoke tunnels, I used the prefabricated chimneys and brick chimneys in the southwest J501 (equipment, decoration). There are many drawbacks in the construction and use: design idealization, Difficulties in construction access, due to the narrow cross-section clearance, the inner edge of the wall edge plastering difficulties, often resulting in more than wipe or wipe, rough surface, construction quality is very poor, and can not be checked; use soon, smoke oil, charcoal attached to the inner wall, The main flank attached to the flues will soon be plugged, and it will be heavily smoked and will not be used. Once the debris has fallen, it cannot be cleaned.
