五、钢 筋 笼 钢筋笼最好是尽量按单元墙段组装成一个整体。如果需要分段接长,其接头以帮条焊为原则。接头应尽量布置在应力小的位置。 钢筋接头原则上应与钢筋等强。单根帮条焊由于钢筋轴线偏心、电弧造成钢材质量变化等等问题,一般认为强度会有所降低。 组装钢筋笼时,要预先定下插入导管的位置,留有足够的空间。由于这部分空间要求上下贯通,因而其周围增设箍筋、连接筋以资加固。 5. Steel cages Reinforced cages are best assembled as a whole by unit wall sections. If you need to lengthen the segment, the joints are based on the principle of strip welding. The joint should be placed as far as possible in the stress-free position. Reinforced joints should in principle be reinforced with reinforcing bars. Single root bar welding is generally considered to have reduced strength due to problems such as eccentricity of the bar axis and changes in the quality of the steel caused by the arc. When assembling rebar cages, place the catheters in advance so that there is enough room. As this part of the space is required to penetrate up and down, additional stirrups and connecting ribs are added around it for reinforcement.
