在钢筋混凝土结构工程中,钢筋的使用长度往往要超过其本身长度,为满足设计要求,施工中就必须要把钢筋接长;另外在配料时虽然注意了长短搭配,但仍不可避免地会有一些短料,为利用这些短料,也需要连接起来使用。所以钢筋接头是施工 In the reinforced concrete structure engineering, the length of the steel bar is often longer than its own length. To meet the design requirements, the reinforcement must be lengthened during construction; Some short materials need to be connected to use these short materials. So the steel joint is the construction
