Device for assembling stand column with bearing platform of bridge

Abstract

The invention discloses a device for assembling a stand column with a bearing platform of a bridge. The device is used for assembling the stand column with the bearing platform of the bridge, and comprises a plurality of stand column steel bars extending out of the bottom of the stand column of the bridge, and a plurality of metal bellows embedded in the bearing platform, wherein the length direction of the metal bellows is parallel to the vertical direction of the bearing platform; the position of the metal bellows corresponds to that of the stand column steel bars, and the number of the metal bellows corresponds to that of the stand column steel bars; and when the stand column of the bridge is assembled with the bearing platform, each of the stand column steel bars is correspondingly inserted into the corresponding metal bellow, and then high-strength mortar or seam abutting glue is arranged at the abutted seam between the stand column and the bearing platform. According to the device disclosed by the invention, the construction period can be shortened, the influence on the surrounding environment can also be reduced, the quality of concrete pouring can be better controlled, and the project cost is low.

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to an assembly device for bridge columns and caps. Background technique [0002] At present, the bridge column usually adopts the cast-in-place process, that is, after the pile foundation construction is completed, part of the column reinforcement is pre-embedded while binding the cap reinforcement, and the concrete pouring of the cap is completed. After the maintenance is completed, the column reinforcement is bound, and then the column concrete is poured. The construction of a column requires about 7 days of maintenance, that is, in the prior art, the on-site construction period is long, the impact on the surrounding environment is large, and the quality of on-site concrete pouring is not stable. Contents of the invention [0003] The purpose of the present invention is to provide an assembly device for bridge columns and caps, which can not only shorten the constructi...
