Method for manufacturing track beam, track bridge, and method for manufacturing track bridge
The invention discloses a manufacturing method of a track beam, a track bridge and a manufacturing method of the track bridge. The manufacturing method of the track beam comprises the following steps: determining the position and shape of a beam bottom surface center line on a trolley surface according to a given beam top surface center line and the offset delta 1 of the beam bottom surface center line relative to the beam top surface center line; determining a rectangular coordinate system on a trolley surface according to the center line of the beam bottom surface; determining the position and shape of the beam side line on the trolley surface according to the beam bottom surface center line and the rectangular coordinate system; according to the beam side lines, the pulling and pressing amount of a plurality of jacks arranged in the length direction of the center line of the trolley face is adjusted, so that the bottom of the left side formwork and the bottom of the right side formwork coincide with the two beam side lines correspondingly; and pouring is conducted between the left side formwork and the right side formwork. According to the manufacturing method of the track beam, the track beam formed through one-time pouring can meet the high-precision manufacturing requirement.
本发明公开了一种轨道梁的制造方法、轨道桥梁以及轨道桥梁的制造方法，轨道梁为缓和曲线梁，轨道梁的制造方法包括以下步骤：根据给定的梁顶面中心线以及梁底面中心线相对于梁顶面中心线的偏移量Δ1确定梁底面中心线在台车面上的位置和形状；根据梁底面中心线确定台车面上的直角坐标系；根据梁底面中心线以及直角坐标系确定梁边线在台车面上的位置和形状；根据梁边线调节沿台车面的中心线的长度方向布置的多个千斤顶的拉压量，使左侧模板的底部和右侧模板的底部分别与两个梁边线重合；在左侧模板和右侧模板之间进行浇筑。采用本发明的轨道梁的制造方法一次浇筑成形的轨道梁能够满足高精度的制造要求。
