Temporary connecting structure for steel pipe arch ring sections

Abstract

The invention discloses a temporary connecting structure for steel pipe arch ring sections. The temporary connecting structure comprises a plurality of lug plates located outside the arch ring sections, all the lug plates are arranged at intervals in the circumferential direction of the arch ring sections, the lug plates are fixedly connected with the outer walls of the steel pipes of the arch ring sections, a plurality of brackets are further connected between the lug plates and the outer walls of the steel pipes, and the lug plates of every two adjacent arch ring sections are connected through bolts. The lug plates and the brackets are arranged on the outer walls of the steel pipes of the arch ring sections, so the internal structures of the steel pipes are not affected, flowing of concrete is not affected at all when the concrete in the pipes is pressed and injected, and the compactness of the concrete in the pipes is guaranteed; all the lug plates are arranged at intervals in the circumferential direction of the arch ring sections, the installation workload of connecting bolts is reduced, and the lug plates are arranged outside the steel pipe, so alignment installation operation is more convenient, the aerial work time is shortened, and the construction risk is reduced; and after permanent weld joint welding of the arch ring sections is completed, the temporary connecting structure can be directly cut off, steel can be recycled, and energy conservation and environmental protection are better facilitated.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a temporary connection structure of steel pipe arch ring segments. Background technique [0002] The steel pipe truss structure of the traditional steel pipe concrete arch bridge (or steel pipe concrete stiff skeleton) is usually constructed by cable hoisting, cable-stayed buckle-hanging method, and the steel pipe truss segments are hoisted symmetrically on both sides. After each segment is hoisted in place, it is used as a temporary Connection, after the temporary connection is in place, install the buckle and anchor cable, and then weld the permanent welds between the segments to complete the segment installation. For example, if Figure 1-Figure 2 As shown, the first segment 1 and the second segment 2 are connected through a temporary connection structure 3 (flange plate), the flange plate is provided with a corbel 31, and the flange plates of the two segments...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a temporary connection structure for steel pipe arch ring segments in view of the problems in the prior art that there are too many bolts in the traditional flange, difficult alignment and insufficient concrete injection in the pipe
