Embodiment 1

[0046] Such as Figure 1-4 As shown, the cap girder of the prefabricated bridge pier in the present invention includes: a prefabricated cap girder component 1, which has a contour section 12 and a variable height section 13 located at the side of the contour section 12, and the bottom is provided with a bridge pier body top The embedded opening 11, that is, the size of the opening 11 is larger than the size of the top of the pier body to accommodate the top of the pier body; the inner mold is arranged inside the prefabricated cap beam member 1, and is A closed structure around the inner wall of the prefabricated cover beam member 1.

[0047] Specifically, the prefabricated cover beam member 1 is a hollow shell structure without a cover made of reinforced concrete, and the thickness of the shell structure is 200-300 mm. In this embodiment, the thickness is preferably 200 mm. Therefore, the prefabricated cover beam member 1 of the shell structure can be lighter and more conveni...

Embodiment 2

[0058] This embodiment also provides a bridge pier structure, such as Figure 8 As shown, it includes the cover girder and the pier body 20 described in the first embodiment; the outer peripheral surface of the pier body 20 is provided with the lower end face of the cover girder and is used for temporary support during the construction process. The annular boss 21 of the prefabricated cover beam member 1, the shape of the annular boss 21 can be further optimized, so that it is not obtrusive and more beautiful after being combined with the cover beam; The main force rib 22, the pier body 20 pier top is embedded in the opening 11 of the prefabricated cover beam member, and one end of the main force rib 22 of the pier body extends into the interior of the prefabricated cover beam member 1; in this embodiment, The cross-section of the pier body 20 is a geometric figure such as a circle or a rectangle, and the main reinforcement 22 of the pier body is HRB400 steel bar or HRB500 ste...

Embodiment 3

[0060] This embodiment provides a bridge, such as Figure 8 As shown, it includes the bridge pier structure described in Embodiment 2, the pad stone provided on the upper end surface of the cover beam, the support 30 provided on the pad stone, and the track beam body installed on the support 30 And the fixing ribs arranged in the cross-bridge direction in the prefabricated cover beam member 1 .

[0061] Further, the support 30 is preferably a cast steel tensile support, and its lower part is connected with a support anchor bar 10 extending into the interior of the prefabricated cover beam member 1, which requires high precision, can effectively transmit loads, and has Certain deformation coordination ability meets the requirements of smooth driving, and at the same time facilitates later assembly installation and alignment adjustment;

[0062] Such as Figure 9 As shown, the pad stone includes: some first reinforcement ribs 40, some second reinforcement ribs 41 and a pad sto...

Abstract

The invention discloses a bent cap of a prefabricated assembled pier. The bent cap is characterized in that the bent cap comprises a prefabricated bent cap component and an inner mold, wherein the prefabricated bent cap component is provided with an equal-height section and variable-height sections located on the sides of the equal-height section, and an open hole where the top of a pier body of the pier is embedded is formed in the bottom; and the inner mold is arranged in the prefabricated bent cap component. On the premise that force bearing reliability and durability of the connecting portion are guaranteed, a monorail bridge assembling requirement and an installation support moderately-adjustable requirement can be met, construction is convenient and quick, and cost reduction and application and popularization are facilitated.

Description

technical field [0001] The invention relates to bridge engineering, in particular to a capping girder of a prefabricated and assembled bridge pier, a bridge pier, a bridge and a bridge assembly construction method. Background technique [0002] In the prior art, both the cap beam and the pier body structure of the monorail bridge pier adopt the traditional construction technology of cast-in-place concrete. Concrete affects construction progress, quality control is difficult, and safety risks are high. [0003] At present, there is no related technical research and practical application of prefabrication and assembly applied to monorail bridge pier cap beam and pier body structure. Contents of the invention [0004] Aiming at the above-mentioned defects of the prior art, the present invention provides a prefabricated and assembled bridge pier cover girder, bridge pier, bridge and bridge assembly construction method, which can meet the requirements of monorail bridges under...
