Prestressed profile steel combined joint construction method
The invention discloses a prestressed profile steel combined joint construction method which comprises the following steps: S1, accurately positioning a prestressed steel strand hole channel for accurately forming a hole in a tubular column, S2, additionally arranging a circular steel tube hole channel to mount a circular steel tube on the tubular column for replacing a corrugated tube, S3, arranging a positioning rib on the outer side of a prestressed steel column, and S4, arranging a prestressed steel strand hole channel on the outer side of the prestressed steel column, in the step S1, a precise positioning mode adopts a three-dimensional measurement technology, a specific numerical value is generated from a three-dimensional coordinate value of a pre-stressed steel strand pore channel by combining a BIM model, and meanwhile, the three-dimensional coordinate is imported by utilizing a digital technology; according to the construction method of the prestressed section steel combined joint, the problems that when corrugated pipes are installed under the existing condition, firstly, the distance and the placing position of the steel bars need to be repeatedly adjusted according to the actual site situation, secondly, the positions of the corrugated pipes penetrating through the tubular column are needed, if holes are not formed in advance, holes are formed in the tubular column later, and the steel bars are dense and hole forming is slow in the positions; and reworking of the vertical steel bars is possibly caused, so that the installation speed of the corrugated pipe is slow, and the construction period is influenced.
本发明公开了一种预应力型钢组合节点施工方法，包括S1：精准定位预应力钢绞线孔道用于在圆管柱上精确开孔，S2：增加圆钢管孔道安装圆钢管于圆管柱上用于取代波纹管，S3：于预应力钢柱外侧布置定位筋，所述步骤S1中精准定位方式采用三维测量技术，结合BIM模型将预应力钢绞线孔道三维坐标值生成具体数值，同时利用数字化技术将三维坐标导入；该预应力型钢组合节点施工方法，通过以上步骤解决了在现有状况下波纹管安装时，首先需要根据现场实际情况，反复地调整钢筋间距、摆放位置，其次，波纹管穿圆管柱位置，如果不提前开孔，在圆管柱上后开孔，此位置钢筋密集，开孔缓慢，很有可能造成竖向钢筋返工，导致波纹管安装速度缓慢，进而影响工期的问题。
