鋼筋加工及安裝作業(yè)工藝與作業(yè)標(biāo)準(zhǔn)一、材料所有鋼筋的種類、鋼號(hào)和直徑應(yīng)符合365JT設(shè)計(jì)圖紙的規(guī)定，II、III、IV級(jí)鋼筋的力學(xué)性能應(yīng)符合《鋼筋混凝土的熱軋帶肋鋼筋》（GB1499—91）的規(guī)定，I級(jí)鋼筋的力學(xué)性能應(yīng)符合《鋼筋混凝土用熱軋光圓鋼筋》（GB13013—91）的規(guī)定。1. 每批鋼筋必須具有生產(chǎn)廠家的質(zhì)保單，并由試驗(yàn)室抽樣試驗(yàn)合格后方可入使用。2. 同一批鋼筋應(yīng)由相同橫截面和同一爐號(hào)的鋼筋組成。每批鋼筋（最多為60t）中取三根，各截取3節(jié)試件，一節(jié)作拉力試驗(yàn)（屈服點(diǎn)、抗拉強(qiáng)度和伸長(zhǎng)度），一節(jié)作冷彎試驗(yàn)，一節(jié)可焊性試驗(yàn)。所有試驗(yàn)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 ......
