Embodiment 1

[0029] Embodiment 1, the present invention is a prefabricated double-column bridge pier that can be assembled quickly. Pouring cavities 5 at both ends of the beam body 4, one end of the segment body 1 is pre-embedded with a convex component 2, and the other end is pre-embedded with a concave component 3 that cooperates with the convex component 2, and the convex component 2 includes four A side wall 201, the four side walls 201 are arranged at intervals in a cross shape and their middle parts are connected and fixed by a horizontal plate 202. The horizontal plate 202 is perpendicular to each side wall 201 and is located on the side of the horizontal plate 202. The wall 201 is pre-buried in the segment body 1, the side wall 201 on the other side of the horizontal plate 202 is exposed outside the segment body 1, and the side wall 201 exposed outside the segment body 1 is provided with a first channel A hole 203 and a second through hole 204, the first through hole 203 and the se...

Embodiment 2

[0035] Embodiment 2. The difference between this embodiment and Embodiment 1 is that the four side walls 201 and the horizontal plates 202 in this embodiment are concrete slabs that are integrally poured, and the side plates and the vertical plates 303 are all steel plates. The housing 301 includes a square housing 301 and a bottom plate fixed at the bottom of the housing 301 , and the bottom plate is fixedly connected with the connecting cylinder 302 . The bottom plate is a steel plate, and is welded to the side plate and the vertical plate 303 respectively, and is prefabricated, which shortens the construction period.

Abstract

The invention discloses a prefabricated double-column pier capable of being quickly assembled and belongs to the technical field of fabricated bridges. The pier comprises a section body with a rectangular section; a convex assembly is pre-embedded in one end of the section body; a concave assembly matched with the convex assembly is pre-embedded in the other end of the section body ; the convex assembly comprises four side walls; the four side walls are arranged at intervals in a cross shape; the middle portions of the four side walls are connected and fixed through a transverse plate; the transverse plate is perpendicular to each side wall; the side walls located on one side of the transverse plate are pre-buried in the section body, and the side walls located on the other side of the transverse plate protrude out of the section body. The prefabricated double-column pier capable of being rapidly assembled is rapid to assemble and firm in connection, can assist in greatly shortening aconstruction period, and can be prefabricated on a large scale.

Description

technical field [0001] The invention belongs to the technical field of prefabricated bridges, in particular to a prefabricated double-column pier that can be quickly assembled. Background technique [0002] Prefabricated bridge prefabrication technology is widely used in modern bridge engineering. In recent years, prefabricated bridge pier construction technology has also begun to rise. The prefabricated bridge pier is mainly assembled by caps and pier segments. Specifically, the "factory" prefabricated segments and cast-in-place caps are assembled and connected on site. Compared with cast-in-place pier columns, prefabricated pier segments have the advantages of large-scale prefabrication, convenient transportation and installation, short construction period, and little interference with the atmospheric environment, road traffic, and citizens' lives. [0003] Bridge prefabrication has many advantages and has become the mainstream of bridge construction. However, due to the ...
