Embodiment 1

[0030] Such as image 3 As shown, a specific embodiment of the prefabricated assembled column bearing platform structure of the present invention includes two parts of the column 1 and the bearing platform 2, which are fixedly connected to form the column bearing platform structure.

[0031] A connecting plane 21 is formed on the surface where the bearing platform 2 and the column 1 are fixedly connected. Preferably, the connecting plane 21 is lower than the upper plane of the platform 2.

[0032] Of course, in other embodiments, the connecting plane 21 can also be flush with the upper plane of the platform 2 or higher.

[0033] A pre-stressed component 3 is fixedly arranged on the connecting plane 21. In this embodiment, the prestressed component 3 is a thick threaded steel bar, which is anchored in the connecting plane 21 and erected in a direction away from the connecting plane 21.

[0034] The column 1 is assembled by several prefabricated column segments 11, 12, 13 and so on. ...

Embodiment 2

[0042] The structure of this embodiment is basically the same as that of the foregoing embodiment, except that the prestressed component 3 is a prestressed steel strand, which is anchored in the connection plane 21 of the bearing platform 2.

[0043] In addition, in this embodiment, the bearing platform 2 and the prefabricated column section 11, and the prefabricated column sections 11, 12, 13 are fixedly connected by cast-in-place concrete.

Embodiment 3

[0045] The assembly and positioning process of the prefabricated assembled column cap structure of the present invention is used to realize the accurate positioning between the prefabricated column segments and the caps and between the prefabricated column segments during the installation process of the prefabricated assembled column cap structure , Including the following steps:

[0046] Step one, refer to image 3 As shown, a pre-stressed component 3 is fixedly arranged in the connecting plane 21 of the bearing platform 2.

[0047] In different embodiments, the prestressed component 3 can be thick rebar or prestressed steel strand. The special feature of the present invention is that the prestressed component 3 also doubles as a positioning component.

[0048] Step two: hoist a prefabricated column section 11 on the connecting plane 21.

[0049] Among them, during the hoisting construction process, it is necessary to ensure that the prestressed component 3 is inserted in the posit...

Abstract

The invention discloses a prefabricated upright post and bearing platform assembled structure, which comprises upright posts and a bearing platform, wherein the upright posts are fixedly connected with the bearing platform to form a whole through a connecting plane of the bearing platform; the upright post is formed by assembling a plurality of prefabricated upright post sections; each prefabricated upright post section is provided with a positioning through hole; and prestressed components are fixedly arranged on the connecting plane of the bearing platform, and the prestressed components also serve as positioning pieces and pass through the positioning through holes. The invention also discloses an assembling and positioning process of the prefabricated upright post and bearing platform assembled structure. The structure design and the process arrangement are adopted, the prestressed components are also used as the positioning pieces, the positioning through holes are reserved in the prefabricated upright post sections, and the positioning pieces are matched with the positioning through holes, so that accurate positioning between the prefabricated upright post section and the bearing platform and between the prefabricated upright post sections is conveniently realized, and good conditions are created for subsequent construction.

Description

Technical field [0001] The invention relates to the technical field of road and bridge construction, in particular to a prefabricated assembled column cap structure. The invention also relates to the assembling and positioning process of the prefabricated assembled column bearing platform structure. Background technique [0002] The prefabricated column (or bridge pier) has been invented for a long time. Compared with the mature on-site pouring construction technology or the overall precast construction technology, it has the advantages of large-scale prefabrication, convenient transportation and installation, and short construction period. But for a long time, the practical application of the assembled bridge pier is very limited. One of the obstacles is the complexity and high technical requirements of the assembled construction process. [0003] Such as figure 1 As shown, CN85202839 discloses a "assembled reinforced concrete prefabricated component", which is a rectangular holl...
