Bolting device between prefabricated decks of prefabricated bridges

Abstract

The invention discloses a bolting device between prefabricated bridge decks of an assembled bridge, relates to the field of bridge construction, and comprises a first bridge deck, a second bridge deck and connecting members, and both ends of the first bridge deck and the second bridge deck are arranged There are steel plates, the ends of the transverse steel bars inside the first bridge deck and the second bridge deck pass through the steel plates and are bent into reserved steel bars, which are interspersed along the middle of the reserved steel bars set at the ends of the first bridge deck and the second bridge deck There are connecting components. In the present invention, the positioning column passes through the middle part of the reserved steel bar, so that the reserved steel bar is clamped in the slot opened by the positioning column, and the reserved steel bar is sandwiched by the upper splint and the lower splint to prevent the reserved steel bar from detaching, and finally The concrete filling layer is poured at the junction of the first bridge deck and the second bridge deck, and the connecting members and the reserved steel bars are connected and fixed without welding, which effectively improves the progress of the project.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a bolting device between prefabricated bridge decks of an assembled bridge. Background technique [0002] During the assembly and installation of prefabricated bridge panels, the connection between two prefabricated bridge panels is usually connected by cast-in-place reinforced concrete. The steel bars reserved for the two prefabricated bridge panels are welded and fixed, and finally concrete is poured. The process of reinforcing steel bars is relatively troublesome; and when two prefabricated bridge panels are connected, it is relatively difficult to locate the prefabricated bridge panels, which affects the work process. In the prior art, the technical scheme of pre-binding steel bars and then welding is adopted, such as patent document CN109778688A , needs to be operated one by one on site, and there is the disadvantage that the U-shaped steel bars at the ends of the prefabri...

[0002] During the assembly and installation of prefabricated bridge panels, the connection between two prefabricated bridge panels is usually connected by cast-in-place reinforced concrete. The steel bars reserved for the two prefabricated bridge panels are welded and fixed, and finally concrete is poured. The process of reinforcing steel bars is relatively troublesome; and when two prefabricated bridge panels are connected, it is relatively difficult to locate the prefabricated bridge panels, which affects the work process. In the prior art, the technical scheme of pre-binding steel bars and then welding is adopted, such as patent document CN109778688A , needs to be operated one by one on site, and there is the disadvantage that the U-shaped steel bars at the ends of the prefabricated slabs on both sides are easily misaligned with each other. In addition, although CN208009273U and CN204209817U have adopted a snap-fit ​​fixing structure designed to surround the built-in card slots on the outside of the vertical steel bars, However, this type of engaging structure can only be used for the outside of the vertical reinforcement, but cannot be fixedly engaged for the transverse U-shaped reinforcement that needs to be arranged in a staggered manner.
