Separate combined type splay saddle and installation method thereof

Abstract

The invention discloses a separate combined type splay saddle and an installation method thereof. The split combination type splay saddle comprises a saddle head and a saddle body which are separated. The bottom of the saddle head is provided with a bottom board, the top of the saddle body is provided with a top board, and a plurality groups of bolt holes corresponding to one another are arranged between the bottom board and the top board. A seam allowance groove is concaved inwards, matched with the bottom board and arranged on the top face of the top board, the saddle head is arranged in the seam allowance groove on the top board of the saddle body in an embedded mode through the bottom board, and the bottom board of the saddle head and the top board of the saddle body are locked tightly and combined together though bolt sets penetrating through the bolt holes corresponding to one another. According to the separate combined type splay saddle, the saddle head and the saddle body matched with each other are formed, therefore, the splay saddle can effectively and reliably achieve easy positioning and installation on the premise that manufacture and transportation are facilitated; the difficulty of alignment and assembling between the saddle head and the saddle body is small, the qualification rate and the accuracy of combination of the saddle head and the saddle body are high, the structural strength is high, the quality is reliable, the practicability is high, and the installation method is particularly suitable for formation of a large-tonnage splay saddle of large-scale suspension bridge engineering.

Description

technical field [0001] The invention relates to a loose cable saddle for a suspension bridge project, in particular to a split and combined loose cable saddle and a method for installing the loose cable saddle. The invention is particularly suitable for a large tonnage loose cable saddle for a large suspension bridge project. Background technique [0002] The scatter cable saddle is an important scatter cable support component arranged between the anchorage and the main tower of the suspension bridge. The smooth transition required by the model. [0003] see figure 1 As shown, the traditional scatter saddle for suspension bridges is mainly composed of a saddle head 1 and a saddle body 2 with an integrated structure. The saddle head 1 is provided with a saddle groove for arranging the main cable, and the bottom of the saddle body 2 is provided with a connecting structure for connecting the base; The saddle head 1 and the saddle body 2 can be formed as an integral casting st...

AI Technical Summary

Problems solved by technology

Undoubtedly, this technology effectively solves the technical problems of the traditional loose cable saddle with integral structure. However, this technology is only a combination of several matching steel plates—that is, the half bodies are connected by bolt pairs. On the one hand, the technology will increase the difficulty of alignment and assembly between the halves, resulting in low pass rate and poor precision. On the other hand, the positioning connection between the halves is only realized by bolt pairs, and its structural strength and reliability Poor performance, which will significantly affect the service life of the loose cable saddle and the overall safety and reliability of the suspension bridge project, especially not suitable for the large tonnage loose cable saddle forming of the large suspension bridge project
