总则一、按照国家标准局、国家建材局关于优等品、一级品和合格品评定产品质量的有关规定,制定混凝土多孔板(高度<120mm)质量评定细则。二、检测依据:《钢筋混凝土工程施工及验收规范》(GBJ204—83),《建筑安装工程质量检验评定标准——钢筋混凝土预制构件工程》(TJ321—76),《冷拔低碳钢丝医预应力混凝土中小构件设计与施工规程》(JGJ19—84)。
General Principles 1. According to the relevant provisions of the National Bureau of Standards and the National Building Materials Bureau on superior products, first-grade products and qualified products to assess product quality, the detailed rules for the quality assessment of concrete porous plates (height < 120mm) are formulated. Second, the test basis: “Construction and acceptance of reinforced concrete engineering” (GBJ204-83), “Building and installation project quality inspection and evaluation standards - prefabricated reinforced concrete structure project” (TJ321-76), "cold drawing low-carbon steel wire pre-medical Design and Construction Rules for Small and Medium-sized Components in Stressed Concrete (JGJ19-84).
