[手绘大样][Detail Drawing] 悬臂板配筋构造(纯悬臂板) [Cantilever slab reinforcement details]

实干、实践、积累、思考、创新。


悬臂板配筋构造(有高差),参考 图集 17G101-11

(1)当悬臂板的跨度较大且板面与内跨标高一致时,由于悬臂支座处的负弯矩对内跨中有影响,当内跨跨度较小时,甚至会出现全跨均为负弯矩,因此上部钢筋应通长配置。板面有高差时应采用分离式配置上部受力钢筋,悬臂板上部受力钢筋在内跨应满足锚固长度的要求。

(2)无内跨纯悬臂板上部受力钢筋伸入支座内的锚固宜采用弯折锚固。当支座宽度满足直线锚固长度la时,上部受力钢筋宜伸至支座远端向下90°弯折,弯折段长度为15d;当支座尺寸不满足直线锚固要求时,水平段投影长度应不小于0.6lab,弯折段长度为15d。

(2)悬臂构件的上部纵向钢筋是受力钢筋,因此要保证其在构件中的设计位置,不可以随意加大保护层的厚度,否则造成板面开裂等质量事故。悬臂板要待混凝土达到100%设计强度后方可拆除下部支撑。

(3)抗震设防烈度为7度(015g)以上,且悬臂板跨度大于2米时,板上下纵向钢筋伸入支座内的锚固长度需满足抗震锚固要求。
