Problems solved by technology

[0003] The problem of the traditional splicing method of prefabricated bridge piers and caps is that there are many pre-embedded steel bars in the caps, all of which need to pass through the reserved holes in the pier body, and the self-weight of the prefabricated pier body is relatively large. There is a certain degree of construction difficulty in the accurate docking of the pier body; the grouting of the holes in the pier body requires a large workload and many uncertain factors

Embodiment 1

[0055] Please refer to figure 1 with figure 2 As shown, a prefabricated bridge pier and a prefabricated platform fast splicing structure, including a prefabricated platform 1, a prefabricated bridge pier 2 and a steel plate assembly 3; the prefabricated platform 1 is provided with a platform groove 11 with an upward opening, the The middle part of the platform groove 11 is provided with a steel pipe concrete tenon 12; the prefabricated pier 2 is vertically arranged and the prefabricated pier 2 is pre-embedded with a hollow steel pipe 21 arranged in the vertical direction, and the hollow steel pipe 21 is located in the prefabricated In the middle of the pier 2 and the lower surface of the hollow steel pipe 21 is flush with the lower surface of the prefabricated pier 2, the prefabricated pier 2 is sleeved on the steel pipe concrete tenon 12 of the prefabricated cap 1 through the hollow steel pipe 21, so The lower surface of the prefabricated pier 2 is flush with the horizontal...

Embodiment 2

[0060] The present invention also provides a construction method for the rapid splicing of prefabricated bridge piers 2 and prefabricated caps 1, which includes the following steps:

[0061] Step 1. Fix the prefabricated cap 1, and fix the prefabricated pier 2 on the prefabricated cap 1 by nesting the steel pipe concrete tenon 12 on the cap groove 11 with the hollow steel pipe 21 of the prefabricated pier 2;

[0062] Step 2. Weld the first steel plate 31 pre-embedded on the prefabricated cap 1 and the second steel plate 32 pre-embedded on the prefabricated pier 2, and weld the third steel plate 33 on the first steel plate 31 pre-embedded on the prefabricated cap 1 , and connected with the second steel plate 32 pre-embedded on the prefabricated pier 2 through bolts 6;

[0063] Step 3: Pour self-compacting concrete 4 whose strength level is one level higher than that of the prefabricated pier 2 between the cap groove 11 and the prefabricated pier 2 .

[0064] To sum up, the pre...

Abstract

The invention relates to the technical field of bridge construction, in particular to a structure for quickly splicing a prefabricated pier and a prefabricated bearing platform and a construction method of the structure. The structure comprises the prefabricated bearing platform, the prefabricated pier and a steel plate component; a bearing platform groove with an upward opening is formed in the prefabricated bearing platform, and a steel pipe concrete tenon is arranged on the middle portion of the bearing platform groove; and the prefabricated pier is vertically arranged, a hollow steel pipearranged in the vertical direction is pre-buried in the prefabricated pier and located in the middle of the prefabricated pier, and the lower surface of the hollow steel pipe and the lower surface ofthe prefabricated pier are flush. The structure has the beneficial effects that the structural design is simple, construction is convenient, only a small part of later-poured concrete needs to be poured, construction efficiency is improved, a construction period of a bridge is shortened, the influence of bridge construction on an urban traffic environment is effectively reduced, and it is guaranteed that the strength of the prefabricated pier is not lower than the strength of a cast-in-place pier.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a structure for quick splicing of prefabricated bridge piers and prefabricated caps and a construction method thereof. Background technique [0002] In order to improve the construction efficiency of the bridge substructure, shorten the construction period, and reduce the interference of bridge construction on the urban environment as much as possible, in recent years, the piers of some urban bridges have been prefabricated and spliced ​​with the caps on site. The common splicing method mostly adopts the reserved channel in the prefabricated pier body, and the pre-embedded steel bar of the cap is exposed for a section. The body and the platform are connected as a whole. [0003] The problem with the traditional splicing method of prefabricated bridge piers and caps is that there are many pre-embedded steel bars in the caps, all of which need to pass through the reser...
