建筑工程和数字2有许多联系,笔者总结了几点,欢迎大家继续补充。1.安全施工方面(1)危险源分为两种:第一类危险源和第二类危险源。(2)施工现场临时用电采用二级漏电保护。(3)高处作业超过2m时,应采取安全防护措施。2.建筑材料(1)在建筑施工上所用的密封材料主要分为两大类型:一种是定型密封材料,一种是非定型密封材料。(2)防火涂料根据受热后的变化分为两种类型,即非膨胀型防火涂料和膨胀型防火涂料。(3)在工程上使用的钢筋分为两类,
There are many links between construction and number 2, I summed up a few points, welcome to continue to add. 1. Safety Construction (1) There are two kinds of dangerous sources: the first type of hazard and the second type of hazard. (2) The temporary use of electricity at the construction site uses secondary leakage protection. (3) When working at a height of more than 2m, safety precautions should be taken. 2. Building materials (1) The sealing materials used in construction are mainly divided into two types: one is the fixed sealing material, one is the non-fixed sealing material. (2) fire retardant coatings are divided into two types according to the changes after heating, that is, non-intumescent fire retardant coatings and intumescent fire retardant coatings. (3) There are two types of steel bars used in engineering,
