Method for positioning and installing stiffening chord gusset plate on steel truss girder
The invention discloses a method for positioning and installing a stiffening chord gusset plate on a steel truss girder, which comprises the following steps of: placing a cross-shaped positioning rod piece with a first prism and a second prism arranged at two ends of a longitudinal rod and a third prism and a fourth prism arranged at two ends of a transverse rod at an upper stiffening chord gusset plate installation position on a bridge deck; the cross center of the cross-shaped positioning rod piece is aligned with the mounting center of the upper stiffening chord gusset plate, and the longitudinal rod and the transverse rod face the longitudinal bridge direction and the transverse bridge direction correspondingly; a total station and a cross-shaped positioning rod piece are matched to measure longitudinal-bridge-direction gradient calculation parameters and transverse-bridge-direction gradient calculation parameters at the mounting position of the upper stiffening chord gusset plate, and a longitudinal-bridge-direction gradient and a transverse-bridge-direction gradient at the mounting position of the upper stiffening chord gusset plate are calculated according to the longitudinal-bridge-direction gradient calculation parameters and the transverse-bridge-direction gradient calculation parameters respectively; and cutting the gradient at the bottom of the upper stiffening chord gusset plate according to the longitudinal-bridge-direction gradient and the transverse-bridge-direction gradient at the mounting position of the upper stiffening chord gusset plate. The invention aims to improve the mounting accuracy of the upper stiffening chord gusset plate.
本发明公开了一种钢桁梁上加劲弦节点板定位安装方法，将纵杆两端设有第一棱镜和第二棱镜以及横杆两端设有第三棱镜和第四棱镜的十字形定位杆件放置在桥面板上的上加劲弦节点板安装位置，使十字形定位杆件的十字中心与上加劲弦节点板安装中心对齐，并且使纵杆和横杆分别朝向纵桥向和横桥向；利用全站仪与十字形定位杆件配合测取上加劲弦节点板安装位置处的纵桥向坡度计算参数和横桥向坡度计算参数，根据纵桥向坡度计算参数和横桥向坡度计算参数分别计算出上加劲弦节点板安装位置处的纵桥向坡度和横桥向坡度；根据上加劲弦节点板安装位置处的纵桥向坡度和横桥向坡度，在上加劲弦节点板的底部切割坡度。本发明目的在于提高上加劲弦节点板安装精确度。
