留槎和接槎正确是保证建筑物整体性的关键一幢房屋的内外墙,一般是分别先后砌筑,因此,常常出现临时间断处。而该处的留槎形式和接砌时的质量好坏,直接关系到建筑物的整体性。这一点,对于抗震设防地区的建筑物尤为重要。据唐山地区的震害调查表明,房屋的破坏一般发生在内外墙的接槎处,而这些破坏多由于施工时留直槎,而且接槎质量很差,砂浆明显地不饱满所引起。 Keeping and picking up the right is the key to ensure the integrity of the building. The inner and outer walls of a house are generally constructed separately, and therefore temporary breaks often occur. The form of the stubborn stay and the quality of the building are directly related to the integrity of the building. This point is particularly important for buildings in earthquake-resistant areas. According to the investigation of the earthquake damage in the Tangshan area, the destruction of houses generally occurred at the joints of the internal and external walls. These damages were mostly caused by straight boring at the time of construction, and the quality of picking was poor and the mortar was obviously not full.
