| 摘 要： | 基于巨大的产量基数必须对中国带肋钢筋升级换代及其相关的资源问题做战略性分析。从资源的极致利用出发,中国地域间显著的差异性和带肋钢筋有限的销售半径将使其升级换代出现目标多元化和地域相关制备技术的显著特点并建议执行地域性标准。在升级换代中宜引入钢筋交变应变基准设计的概念以确保抗震性。从资源友好出发分析了现有带肋钢筋Q235+Mn型和Q235+Mn+MA型强韧化技术的不足,强调焊接连接不利于资源的有效利用;宜开展对用于机械连接的Q235+C型强韧化技术的探讨,以获得更加资源友好的效果,给出了初步的实验室研究结果。 |

| Abstract: | The strategy discussion on the updating of ribbed bar and related resource problem was necessary based on its massive production.In point of view of extreme resource utilization,the outstanding local difference in China and the limited sales radius of ribbed bar brought the multi-purpose and local preparing technique to the ribbed bar updating and then the local standard was recommended.The concept of alternating strain base design should be introduced in the ribbed bar updating to ensure the anti-seismic properties of rebar.The resent(Q235+Mn) and(Q235+Mn+MA) strengthening pattern had the shortage of the resource and the welding jointing should not utilize the resource full.It was recommended to develop the(Q235+C) strengthening pattern for the mechanical jointing of rebar in order to get better effect of resource utilization.The preliminary lab result was given. |
