A main cable saddle saddle head structure and its forming method

Abstract

The invention discloses a main cable saddle head structure and a forming method thereof. The saddle head structure comprises a saddle head body provided with a saddle groove, multiple partition plates are vertically welded in the saddle groove in a groove weld manner, and each partition plate is of an integral structure. The forming method of the saddle head structure includes the steps that firstly, the saddle head body and the partition plates meeting design requirements are manufactured, and corresponding slope grooves are machined in the saddle groove and the partition plates correspondingly according to the design requirements; secondly, the corresponding partition plates are assembled on other welded parts, except for two to four welded parts in the center of the saddle groove, in the saddle groove one by one according to the welding sequence of conducting symmetric welding from the two sides to the center and are welded in the groove weld manner; and thirdly, the corresponding partition plates are assembled on all the welded parts in the center of the saddle groove one by one and are welded in the groove weld manner. According to the main cable saddle head structure and the forming method thereof, the strength of connecting structures between the partition plates and the saddle groove and the structural strength of the partition plates are greatly improved, and the anti-shearing capability of a whole saddle head is high.

Description

technical field [0001] The invention relates to a main cable saddle of a suspension bridge, in particular to a saddle head structure and a forming method of the saddle head structure. Background technique [0002] The main cable saddle is a permanent structural part used to support the main cable of the suspension bridge. The common main cable saddles are all-cast, all-welded and cast-welded. Among them, the cast-welded main cable saddle absorbs the advantages of the all-cast and all-welded main cable saddles, that is, the saddle head with a complex structure is formed by casting steel, and the base with a relatively simple structure is welded and formed by steel plates. In this way, the advantages of the structural strength and manufacturing method of the all-cast and all-welded types are better utilized, and the contradiction between the simplified manufacturing process and the rational use of materials is effectively resolved. [0003] In the cast-welded main cable saddl...

AI Technical Summary

Problems solved by technology

Although this kind of saddle head structure is relatively convenient and easy to form, due to the split structure of the partition and the welded combination structure of the partition on the saddle groove, the structural strength of the partition itself and the connection between the saddle body and the saddle body The strength is poor, and the shear resistance of the entire saddle head is weak, which is not conducive to improving the stability and reliability of the permanent main cable saddle structure in suspension bridge engineering
