受力钢筋的混凝土保护层厚度有三个具体的数值:1.受力钢筋混凝土保护层的最小厚度值;2.验收批内质量检查验收受力钢筋的混凝土保护层的允许偏差数值;3.结构实体受力钢筋混凝土保护层厚度检验时的允许偏差数值。受力钢筋混凝土保护层厚度的控制,要按照《混凝土结构工程施工质量验收规范》(GB50204—2002,2011年版)、国家标准图集和建筑设计文件中的相关规定实施。钢筋混凝土保护层最小厚度的控制直接影响到建筑物结构的承载力、耐久性、防火等各项性能,
Concrete reinforcement thickness of the reinforced concrete has three specific values: 1. The minimum thickness of the reinforced concrete protective layer; 2. Acceptance within the batch inspection Acceptance reinforced concrete protective layer of the allowable value; 3. Structure The value of allowable deviation in the test of thickness of concrete reinforced concrete protective layer. The control of the thickness of reinforced concrete protective layer should be implemented in accordance with the relevant provisions of “Code for Acceptance of Construction Quality of Concrete Structures” (GB50204-2002, 2011 edition), national standard atlas and architectural design documents. The minimum thickness of reinforced concrete protective layer directly affects the structure of the bearing capacity of the structure, durability, fire and other properties,
