Problems solved by technology

[0003] The existing pier column construction process includes measurement and setting out, scaffolding construction, steel bar processing and installation, formwork installation, concrete pouring, concrete curing, formwork removal and tie beam backfilling. During pier column construction, formwork installation, concrete pouring, and concrete curing are required. Concrete maintenance takes seven days if it is less, and one month if it is more, which greatly prolongs the construction time of construction personnel and reduces the construction efficiency of construction personnel during pier construction.

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] refer to figure 1 , is a spliced ​​pier column for an overpass disclosed by the present invention, comprising a base 1 and a column arranged on the base 1 .

[0032] Such as figure 1 As shown, the column body includes a plurality of splicing columns 11 , and in order to splice the plurality of splicing columns 11 , each splicing column 11 is set to be prefabricated in a factory.

[0033] combine figure 1 and figure 2 In order to facilitate the splicing together of adjacent splicing columns 11 and prevent positional deviation between adjacent splicing columns 11, a plurality of sets of mutually matching slots 151 and Insertion strip 15, multiple groups of slots 151 and insertion strip 15 are evenly distributed along the circumferential position of splicing column 11, no slot 151 is set on the uppermost splicing column 11, and no inserting strip 15 ...

Abstract

The invention relates to an overpass spliced pier. The overpass spliced pier comprises a base and a pier main body arranged on the base, wherein the pier main body comprises a plurality of splicing pier bodies which are prefabricated by a factory, the edge, far away from the base, of each splicing pier body is provided with a plurality of first connecting plates, the plurality of first connectingplates are uniformly arranged along in circumferential direction of the splicing pier body, the edge, close to the base, of each splicing pier body is provided with a plurality of second connecting plates, the plurality of second connecting plates are uniformly arranged along in circumferential direction of the splicing pier body, the first connecting plates and the second connecting plates on theadjacent splicing pier bodies are in butt joint with each other and are oppositely arranged, and the first connecting plates and the second connecting plates on the adjacent splicing pier bodies areconnected together through first bolts and nuts. The plurality of splicing pier bodies are mounted by adopting the first bolts and the nuts, the construction time of constructors is shortened, and theconstruction efficiency during pier construction of the constructors is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an overpass spliced ​​pier column. Background technique [0002] Pier column, that is, the lower load-bearing object used to carry the upper structure in civil engineering. Most of the cross-sections of piers are circular, and there are also heterosexual piers such as ellipse, square, curve, and parabola. It is an important part of highway bridges, railway bridges, sidewalks and other bridges, overpasses, ramp bridges, flyovers and other projects. [0003] The existing pier column construction process includes measurement and setting out, scaffolding construction, steel bar processing and installation, formwork installation, concrete pouring, concrete curing, formwork removal and tie beam backfilling. During pier column construction, formwork installation, concrete pouring, and concrete curing are required. Concrete maintenance needs seven days at least, and one mon...
