Problems solved by technology

[0003] After the pole is transported to the hoisting site, the installation of the butt plate is the most time-consuming process before the pole is hoisted. However, most of the existing construction uses manual cooperation with machinery to install the butt plate on the pole one by one. This method is for smaller , lighter butt plate, the installation speed is faster, but it is not suitable for a larger butt plate with a weight of nearly two tons

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] see Figure 1 to Figure 7 , a method for installing the butt joint plates of box-shaped rods of steel structure arch bridges. In this method, before the rods are hoisted, after all the butt-joint plates on the inner and outer sides of each side of the box-shaped rods are spliced, the butt joints are manually cooperated with forklifts. The board is installed as a whole to the corresponding position of the bar.

[0021] The following takes the installation of the butt plate of the top plate on the rod as an example to illustrate:

[0022] The butt plates corresponding to the top plate 4 on the rod are divided into four pieces: one outer butt plate 1 and three inner butt plate 2. When assembling, the four butt plates are stacked together according to the spatial position, and each inner butt plate 2 and the outer butt plate 1 are fixed with thre...

Abstract

The invention relates to an installation method of box-shaped rod piece butt plates of a steel structure arch bridge. The method includes the steps that before the butt plates are installed, the corresponding butt plates are assembled, the mid-span distance and the included angle of the butt plates on the inner side and the outer side are adjusted to set values, after rod pieces are completely inserted in the butt plates, the front-back positions of the rod pieces and the butt pates reach the designed positions, and the butt plates can be installed in place only through left-right slight adjustment of a worker. By the adoption of the method, position adjustment of the butt plates in the air is reduced, and the installation efficiency of the butt plates is greatly improved for the heavy rodpieces uneasy to control.

Description

technical field [0001] The invention relates to a butt joint method of steel structure arch bridge rods, in particular to a method for installing a box-shaped rod butt joint plate of a steel structure arch bridge. Background technique [0002] Most of the existing steel structure arch bridges adopt the plug-in butt joint method for the butt joint of the rods, that is, the butt plate is installed at the end of the suspenders, and the butt plate is not installed on the top, and then inserted into the top of the suspenders to complete the connection between the rods. Butt joint; or install the butt plate on the top of the bar and not install the butt plate at the tail to butt the bar. [0003] After the pole is transported to the hoisting site, the installation of the butt plate is the most time-consuming process before the pole is hoisted. However, most of the existing construction uses manual cooperation with machinery to install the butt plate on the pole one by one. This me...
