近年来,多层砖混住宅的工程质量有了很大提高,但仍存在一些不合理、不规范的施工问题,影响了多层砖混住宅的工程质量。一、基础砖墙上室内暖气沟的留设多层砖混住宅室内暖气沟往往沿基础内墙走 n 字形,大大削弱了内外墙基础的整体性。然而,不合理的施工往往雪上加霜,在钢筋混凝土条形基础或筏板基础上,基础砖墙高度一般为1500mm 左右,而暖气沟为800mm 宽、1000mm 高,所以暖气沟底还应砌400～500mm 的基础墙。有些施工人员不重视这几层砖墙,直接从条形基础或筏板上开始留暖气沟,使有暖气沟的内外墙完全断开;
In recent years, the quality of multi-storey brick houses has been greatly improved, but there are still some unreasonable and non-standard construction problems that affect the quality of multi-storey brick houses. First, the basic brick wall to set up indoor heating ditches Multi-storey brick mixed residential interior heating ditch often along the basis of the internal wall to take the n-shaped, greatly weakened the integrity of the external walls of the foundation. However, irrational construction is often worse. On the basis of reinforced concrete strip foundation or raft foundation, the height of the basic brick wall is generally about 1500mm, while the heating groove is 800mm wide and 1000mm high, so the bottom of the heating ditch should be built 400 ~ 500mm The foundation wall. Some construction workers do not attach importance to these layers of brick walls, directly from the strip foundation or raft left to warm the ditch, so that a warm ditch completely cut off the internal and external walls;
