Reinforced concrete beam bridge pre-camber positioning device and construction method thereof
The invention provides a reinforced concrete beam bridge pre-camber positioning device and a construction method thereof, and belongs to the technical field of bridges, the reinforced concrete beam bridge pre-camber positioning device comprises a sliding rail, first positioning frames, second positioning frames, elastic steel plates and infrared emitters, and the second positioning frames are slidably arranged on the two sides, located in the length direction of a beam bridge, of each first positioning frame; the height of the first positioning frame and the height of the second positioning frame are arranged in a lifting mode, the height positions after lifting are fixed, angle scales are fixedly arranged on the first positioning frame and the second positioning frame, and clamping plates are rotationally arranged at the positions, located in the centers of the angle scales, of the first positioning frame and the second positioning frame. The clamping plates are provided with clamping grooves used for clamping the elastic steel plates, the elastic steel plates are evenly provided with a plurality of through holes used for containing the infrared emitters in the length direction of the elastic steel plates, and the infrared emitters are arranged in the through holes of the elastic steel plates on one side. The method has the advantages that the pre-camber of the beam bridge can be quickly and accurately positioned during construction of the beam bridge, and the construction efficiency is improved.
本发明提供了一种钢筋混凝土梁桥预拱度定位装置及其施工方法，属于桥梁技术领域，包括滑轨、第一定位架、第二定位架、弹性钢板以及红外线发射器，每个第一定位架位于梁桥的长度方向的两侧均滑移设置有第二定位架，第一定位架与第二定位架的高度均呈升降设置且升降后的高度位置固定，第一定位架与第二定位架上均固定设置有角度盘，第一定位架与第二定位架上位于角度盘中心的位置均转动设置有夹板，夹板上开设有用于供弹性钢板卡接的夹槽，弹性钢板沿自身长度方向均匀开设有多个用于放置红外线发射器的通孔，红外线发射器设置在其中一侧的弹性钢板的通孔内。本发明具有在梁桥建造时便于对梁桥预拱度进行快速精确定位并提升建造效率。
