Cross beam vertical rotation system for arch tower cable-stayed bridge and construction method thereof
The invention discloses a cross beam vertical rotation system for an arch tower cable-stayed bridge and a construction method thereof. The arch tower cable-stayed bridge comprises a bridge tower, a main beam and a cross beam section, and the bridge tower is an arch bridge tower and is formed by splicing a left side tower and a right side tower which are symmetrical; a cross beam section is arranged on each side tower, is connected with the main beam and is used for improving the transverse stress and stability of the main beam; the vertical load of the main beam is transmitted to a bridge tower through a stay cable; wedge-shaped blocks are arranged on the two sides of the main beam; the cross beam vertical rotation system comprises a locking device and a vertical rotating device, the crossbeam section is of a cuboid structure, and the upper end of the cross beam section is matched with the wedge-shaped block on the main beam in shape; the locking device is matched with the vertical rotating device to fix the cross beam section on the inner side of the side tower, after the bridge tower and the main beam are built, the height of the upper end of the cross beam section can be adjusted, the upper end of the cross beam section is vertically rotated to the transverse wedge-shaped block of the main beam, and the main beam and the cross beam are connected into a whole. According to the system and the construction method thereof, operation of an existing line is not affected, space is saved, and manufacturing cost is reduced.
本发明公开一种用于拱塔斜拉桥的横梁竖转系统及其施工方法，拱塔斜拉桥包括桥塔、主梁和横梁节段，所述桥塔为拱形桥塔，由左右两个对称的侧塔拼接而成；每个侧塔上设置一个横梁节段与主梁连接，用于改善主梁的横向受力及稳定；主梁竖向荷载通过斜拉索传递至桥塔；主梁两侧设置有楔形块；所述横梁竖转系统包括锁定装置和竖转装置，所述横梁节段为长方体结构，上端形体与主梁上的楔形块相适配；所述锁定装置配合竖转装置可先将横梁节段固定在侧塔的内侧，待桥塔和主梁搭建完毕后，可调整横梁节段上端高度，将横梁节段的上端竖转至主梁的横向楔形块上，将主梁与横梁连接为一体。本发明的系统及其施工方法不影响既有线路运行，节约空间，降低造价。
