《钢筋混凝土结构设计规范》(TJ 10-74)和《钢筋混凝土工程施工及验收规范》(GBJl 0-65修订本)对冷拉钢筋均作了有关的规定。但是,在执行过程中,由于规范中的某些规定不明确,各单位的施工水平、设备条件、质量管理等方面不尽相同,因而目前冷拉钢筋的施工方法不一,质量难以保证。1976年以来,有关单位就单控冷拉钢筋 The “Code for Design of Reinforced Concrete Structures” (TJ 10-74) and “Code for Construction and Acceptance of Reinforced Concrete Engineering” (Revised Edition of GBJl 0-65) have all made relevant provisions for cold drawn steel bars. However, in the implementation process, due to some ambiguities in the specifications, the construction level, equipment conditions, and quality management of each unit are not the same. Therefore, the construction methods of cold drawn steel bars are not the same, and the quality is difficult to guarantee. Since 1976, the relevant units have controlled cold drawn steel bars
