在建筑基础材料中被普遍采用的建筑材料就是毛石,它具有抗压强度高、材料来源广泛、价格低廉、施工方便等优点。但是毛石砌体的整体性能较差,所以规范规定:毛石墙须设拉接石。拉接石应均匀分布,相互错开,一般每0.7m~2墙面至少应设置一块,且同皮内的中距不应大于2M。拉接石的长度,如墙厚≤40cm,应等于墙厚;墙厚>40cm,可用两块拉接石内外搭接,搭接长度不应小于15cm,且其中一块长度不应小于2/3墙厚。由
The commonly used building material in building foundation materials is rubble, which has the advantages of high compressive strength, wide source of materials, low cost, and easy construction. However, the overall performance of the masonry masonry is poor, so the specification states that: The connecting stones should be evenly distributed and staggered. Generally, at least one wall should be provided for each 0.7m~2 wall surface, and the median distance within the same skin should not be greater than 2M. The length of the braced stone, if the wall thickness is ≤40cm, shall be equal to the wall thickness; the wall thickness shall be >40cm, and two bracing stones may be used to bridge the inside and outside. The length of the lap joint shall not be less than 15cm, and one of the lengths shall not be less than 2/3 Wall thickness. by
