Pier bent cap for preventing beam body from overturning and using method thereof

Abstract

The invention discloses a pier bent cap for preventing a beam body from overturning, which is characterized in that a prefabricated assembly component is arranged on a bent cap body; the top of the prefabricated assembly component arranged at the edge part is provided with a spanned edge beam; the edge beam extends outwards to form overhanging arms, anti-seismic check blocks stacked upwards are arranged at the two side ends of the bent cap body, there is a gap between the top of the anti-seismic check block and the lower edge of the overhanging arm, the lower edge of the overhanging arm tiltsupwards to form an included angles with the horizontal plane, a wedge-shaped structure with a large outer opening and small inner part is formed by each gap, and temporary supporting blocks are arranged in the gaps. When the pier bent cap is used, the two side ends of the bent cap body are provided with the anti-seismic check blocks extending upwards; the gap exists between the top of the anti-seismic check block and the outer overhanging arm of the edge beam of the assembly type upper structure, and the gaps can be filled with the temporary supporting blocks when matched components of the pier bent cap are installed, so that the overall rigidity is improved, and the risk that the beam body overturns outwards in the erecting and detaching process is avoided. Therefore, the edge beams can be sequentially mounted or dismounted with the guardrails, and the safety degree and the construction efficiency of mounting or dismounting operation are improved.

Description

technical field [0001] The present invention mainly relates to the technical field of bridge design and construction, in particular to a bridge pier cover girder for preventing girder body from overturning and its use method, in particular to a method for preventing prefabricated bridge superstructure girder body from being installed and dismantled. Overturned cap beam structures and methods of use thereof. Background technique [0002] Prefabricated bridges have received extensive attention and research due to their many advantages such as shortening the construction period, improving quality and efficiency, reducing the impact of construction on the current traffic, and adapting to modern and intensive production development models. The application of prefabricated assembly technology in the superstructure of concrete bridges has a history of several decades. At present, the commonly used structural forms such as hollow slabs, T beams, and small box girders are typical pre...
