框架填充墙砌体拉结筋“植筋法”施工工艺探析

Study on the Planting Reinforcement Construction Techniques of Infill Wall in Frame with Tie Bar

框架填充墙砌体拉结筋,采用＂植筋法＂施工,拉结筋定位准确,方便墙体砌筑;不直接预埋拉结筋,也不需事先在钢筋混凝土结构柱（墙）中设置埋件,而且可以按砌块模数进行定位设置。与预埋方法比较,采用＂植筋法＂时,模板不需钻孔穿筋,避免了因混凝土施工时,由于振捣等原因而造成的拉结筋移位、歪斜,拉结筋施工时剔凿过深或面积过大,影响主筋保护层和削弱混凝土结构断面尺寸等质量问题。

Employing the method of planting reinforcement to anchor precisely and make building walls convenient,infill wall in frame with tie bar can not only save the effort of tie bars directly and beforehand or place embedded parts in concrete structure in advance,but also anchor according to the number of blocks.Compared with embedment beforehand, planting reinforcement is better in that it doesn＇ t need to do drilling and thus avoids quality problems such as displacement or distortion due to vibrating in concrete operation,affecting the protecting function of the main reinforcing steel and reducing the concrete cross section size,etc.because of digging too much in tie bar operation.
