Prefabricated tubular column steel bar concentric and coaxial positioning device and positioning method
The invention provides a prefabricated tubular column steel bar concentric and coaxial positioning device and method, and belongs to the technical field of bridge construction, the prefabricated tubular column steel bar concentric and coaxial positioning device comprises a steel outer mold, a steel inner mold and a steel outer mold, the steel outer mold is arranged on the outer side of a steel reinforcement cage in a sleeving mode, and the steel outer mold and the steel reinforcement cage are coaxially arranged; the top axis positioning mechanism is arranged at the top of the reinforcement cage, connected with the top of the steel outer mold and used for clamping and limiting the top of a vertical steel cable in the reinforcement cage; and the bottom axis positioning mechanism is arranged at the bottom of the reinforcement cage, connected with the bottom of the steel outer mold and used for clamping and limiting the bottom of the vertical steel cable in the reinforcement cage. The vertical steel cable in the reinforcement cage is concentrically and coaxially positioned through the clamping and limiting effects of the top axis positioning mechanism and the bottom axis positioning mechanism, the phenomena of centrifugal rotation, torsion, circumferential sliding and the like caused by deviation of the vertical steel cable of the reinforcement cage due to stress in the pouring process of the prefabricated tubular column are avoided, and the construction quality of the prefabricated tubular column is improved. And the overall quality of the prefabricated tubular column is improved.
本发明提出了预制管柱钢筋同心同轴定位装置及定位方法，属于桥梁施工技术领域，包括：钢外模，套设在钢筋笼的外侧，且与所述钢筋笼同轴设置，所述钢筋笼用于浇筑预制管柱；顶部轴心定位机构，设置在钢筋笼的顶部，并与钢外模的顶部连接，用于对钢筋笼中竖向钢索的顶部进行夹持限位；以及底部轴心定位机构：设置在钢筋笼的底部，并与钢外模的底部连接，用于对钢筋笼中竖向钢索的底部进行夹持限位。本发明通过顶部轴心定位机构和底部轴心定位机构的夹持限位作用对钢筋笼中的竖向钢索进行同心同轴定位，避免在预制管柱浇筑的过程中，钢筋笼的竖向钢索因受力而发生偏移，导致出现离心旋转、扭转和环向滑动等现象，提高了预制管柱的整体质量。
