Prefabricated box girder expansion joint embedded bar positioning device
The invention relates to the technical field of bridge construction, and discloses a prefabricated box girder expansion joint embedded bar positioning device which comprises two guide rails, the two guide rails are parallel to each other, sliding seats are slidably arranged at the top ends of the two guide rails, telescopic columns are fixedly mounted at the top ends of the two sliding seats, and rotating seats are rotatably mounted at the top ends of the telescopic columns; a telescopic supporting beam is connected between the two rotating seats, and a plurality of supporting rods are connected to the bottom end of the telescopic supporting beam; accurate movement and positioning of the expansion joint embedded bars in the longitudinal direction, the corner direction, the vertical direction and the transverse direction can be achieved, the situation that due to the fact that the installation precision of the embedded bars in a traditional technology is low, broken welding and re-welding or repeated steel bar correction are needed, the bridge construction progress is affected is avoided, positioning and installation of the box girder expansion joint embedded bars with different oblique crossing angles can be achieved, and the construction efficiency is improved. The expansion joint embedded bars do not need to be welded and fixed to the box girder top plate main bars, and the situation that the main bars have quality defects such as welding damage and weld beading, and structural durability and bearing capacity are affected is avoided.
本发明涉及桥梁施工技术领域，公开了一种预制箱梁伸缩缝预埋筋定位装置，包括两个导轨，两个导轨相互平行设置，两个导轨的顶端均滑动设置有滑座，两个滑座的顶端均固定安装有伸缩柱，伸缩柱的顶端转动安装有旋转座，两个旋转座之间连接有伸缩支撑梁，伸缩支撑梁的底端连接有多个支撑杆；本发明能够实现对伸缩缝预埋筋纵向、转角、竖向及横向四个维度的精确移动及定位，避免了传统工艺预埋筋安装精度低导致需破焊并重新焊接或反复矫正钢筋，影响桥梁施工进度，可实现不同斜交角度箱梁伸缩缝预埋筋的定位安装,无须将伸缩缝预埋筋焊接固定于箱梁顶板主筋，避免了主筋出现焊伤、焊瘤等质量缺陷，影响结构耐久性和承载力。
