钢筋加工及安装施工作业工艺标准.doc

钢筋加工及安装作业工艺与作业标准一、材料所有钢筋的种类、钢号和直径应符合365JT设计图纸的规定，II、III、IV级钢筋的力学性能应符合《钢筋混凝土的热轧带肋钢筋》（GB1499—91）的规定，I级钢筋的力学性能应符合《钢筋混凝土用热轧光圆钢筋》（GB13013—91）的规定。1. 每批钢筋必须具有生产厂家的质保单，并由试验室抽样试验合格后方可入使用。2. 同一批钢筋应由相同横截面和同一炉号的钢筋组成。每批钢筋（最多为60t）中取三根，各截取3节试件，一节作拉力试验（屈服点、抗拉强度和伸长度），一节作冷弯试验，一节可焊性试验。所有试验必......
Steel processing and installation standards processes and operations of a materials of all types of steel, steel and the diameter should be consistent with the provisions of 365JT design drawings, II, III, IV level should be consistent with the mechanical properties of steel "reinforced concrete hot rolled ribbed bar "(GB1499-91) requirements, I grade the mechanical properties of steel should conform to" the reinforcement of concrete hot-rolled round bar "(GB13013-91) requirements. 1. Each batch of steel manufacturers warranty must have a single, random testing by the laboratory until they have passed into use. 2. With a number of steel cross-section and the same should be the same heat number of steel composition. Each batch of steel (up to 60t) were obtained from 3, the interception of three specimens, one for tensile testing (yield point, tensile strength and elongation), one for cold test, a solderability test. All tests will be ......
