Description

Technical Field

[0001] The utility model belongs to the technical field of civil engineering, in particular to a hydraulic climbing formwork device for high pier columns of bridges. Background Art

[0002] A bridge generally refers to a structure built on rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient. Bridges are generally composed of superstructures, substructures, supports, and auxiliary structures. The superstructure is also called the span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; the supports are force transmission devices installed at the supporting places of the span structure and the piers or abutments; the auxiliary structures refer to the bridge head slabs, conical slope protection, revetments, diversion projects, etc.

[0003] Piers are the lower load-bearing objects used to support the upper structures in civil engineering. The cross-section of piers is mostly circular, but there are also elliptical, square, curved, parabolic and other special-shaped piers. They are important components in highway bridges, railway bridges, sidewalks, overpasses, ramp bridges, flyovers and other projects.

[0004] During the process of pouring concrete in the pier, a formwork system is needed to shape the concrete. The problem with the above technology is that most bridge piers are wide at the top and narrow at the bottom. The existing formwork system directly uses a fixed formwork for the control of the elevation angle of the formwork and the movement of the formwork, and the elevation angle cannot be adjusted according to needs.
