Bridge top rotation body structure

Abstract

The invention discloses a bridge top rotation body structure which comprises a rotation body component. Steel plates are paved in the rotation body component, a sliding way is vertically arranged in the rotation body component, the top of the sliding way is positioned on the inner top surface of the rotation body component, the bottom portion of the sliding way is arranged on the inner bottom surface of the rotation body component, a sliding body is horizontally mounted on the sliding way, protection plates are connected among two sides of the sliding way and the rotation body component and obliquely arranged on the sliding way and the rotation body component, bearing plates are mounted on the lower surface of the protection plates, the top of the bearing plates is integrally connected with the protection plates, the bottom of the bearing plates is fixed on the inner bottom surface of the rotation body component, the bottom of the rotation body component is connected on a rotating seat, and the rotating seat is connected with the rotation body component through a rotating rod. The bridge top rotation body structure can effectively bear local pressure, overall stress demand is met, pier top operating space is enlarged, safety is improved, design difficulty of the rotation body structure is greatly reduced, structure reliability can be effectively improved, tonnage of the rotation body is decreased, and engineering cost is reduced.

Description

technical field [0001] The invention relates to a top swivel structure, in particular to a bridge top swivel structure. Background technique [0002] The bridge swivel system is generally used in flyover bridges or bridges that are difficult to adopt traditional construction methods. Bridge swivel construction refers to a construction method in which the bridge structure is poured or spliced ​​at a position other than the design axis, and then swiveled. Because the swivel construction method changes complex and highly technical aerial work and water work into land-based work on the shore, it is not only safe and of good quality, but also does not interfere with traffic during the construction of navigable rivers or flyover bridges with frequent vehicles. , uninterrupted navigation, and less damage to the surrounding environment, so it is often used in bridge construction. However, the traditional bridge swivel system has the disadvantages of complex structure and troubleso...
