当受力钢筋直径等于或小于22mm时,GBJ10-89规范规定可采用非焊接的搭接接头。但现行钢筋混凝土工程施工及验收规范GBJ204-83第3.5.1条、第3.5.3条、第3.5.5条,均未写入钢筋绑扎接头搭接长度范围内箍筋间距应加密。而GBJ10-89混凝土结构设计规范第6.1.14条、第7.2.7条、第7.3.2条已写入钢筋绑扎接头在搭接长度范围内,箍筋间距应加密。当搭接钢筋受拉时 When the diameter of the stressed bar is equal to or less than 22mm, the GBJ10-89 specification provides for non-welded lap joints. However, the current reinforced concrete construction and acceptance specification GBJ204-83 Article 3.5.1, Article 3.5.3, Article 3.5.5, are not written in the lashing length range of reinforced binding joints should be encrypted. The GBJ10-89 concrete structural design specifications 6.1.14, 7.2.7, 7.3.2 have been written into the steel banding joints in the lap length range, stirrup spacing should be encrypted.
