(中國建筑科學(xué)研究院 北京 100013)[提要] 介紹了冷軋帶肋鋼筋及鋼筋焊接網(wǎng)在我國的發(fā)展和應(yīng)用概況。550級鋼筋宜用作鋼筋砼結(jié)構(gòu)構(gòu)件的受力主筋、架立筋、箍筋和構(gòu)造鋼筋以及制作鋼筋焊接網(wǎng)。650級、800級、970級和1 170級鋼筋宜用作預(yù)應(yīng)力砼結(jié)構(gòu)構(gòu)件的受力主筋。
[關(guān)鍵詞] 冷軋帶肋鋼筋 現(xiàn)澆砼 預(yù)應(yīng)力砼構(gòu)件 鋼筋焊接網(wǎng)This paper briefly describes the engineering practice and developing prospect of cold-rolled ribbed steel wires and welded steel fabric in China. Grade 550 cold-rolled ribbed steel wire may be used as main bearing reinforcement, auxiliary reinforcement, stirrups, detailing requirements reinforcement and welded steelfabric in the members of reinforced concrete structures. Grade 650, grade 800, grade 970 and grade 1 170 cold-rolled ribbed steel wires may be used as main bearing reinforcement in the members of prestressed concrete structures.
Keywords: cold-rolled ribbed steel wire; concrete in situ; prestressed concrete member; welded steel fabric
