Abstract

The invention relates to a reinforced concrete spherical hinge structure of a swing bridge and a manufacturing process thereof. The reinforced concrete spherical hinge structure comprises an upper turntable used for supporting a rotating structure and a lower turntable of a basic connection body and is characterized in that an inverted conical structure formed by pouring the reinforced concrete is arranged at a lower side of the upper turntable, an upper grinding cover formed by pouring the reinforced concrete is coaxially arranged at a center of the lower end of the inverted conical structure, a lower grinding center matched with the upper grinding cover in a rotating positioning manner is arranged at an upper side of the lower turntable, and the lower grinding center is formed by pouring the reinforced concrete. The reinforced concrete spherical hinge structure of the swing bridge has the advantages of simple structure, low manufacturing cost, simple manufacturing process and convenience for installation.

Description

technical field [0001] The invention relates to a reinforced concrete spherical hinge structure of a swivel bridge and a manufacturing process thereof. Background technique [0002] Most of the existing reinforced concrete spherical hinge structures of swivel bridges are made of steel structures. Such spherical hinge structures must be produced by qualified professional manufacturers, and then transported to the site for installation, which is expensive, complicated in structure, complex in process, and auxiliary equipment. High requirements, difficult on-site installation, inconvenient transportation and other issues. For example: [0003] 1. The utility model patent with the patent number CN200420060993 discloses a spherical hinge capable of rotating the load. It is characterized in that: the swivel spherical hinge structure includes an upper plate, a lower plate, an upper half of the spherical hinge, and a lower half of the spherical hinge. Department, traction turntabl...
