specific Embodiment

[0029] like Figure 1-Figure 2 As shown, a specific embodiment of the combined connection structure and assembly method of the prefabricated bridge pier column and the cap socket and the socket of the present invention includes the following steps:

[0030] Prefabricated column 2, prefabricated column 2 includes column exposed end 22 and column embedded end 23, several steel bars 24 are embedded in prefabricated column 2, and steel bar 24 is provided with the free end 25 that stretches out certain length from the bottom end of column embedded end 23; The skilled person should know that the cross-section size and reinforcement of the column embedded end 23, as well as the number of steel bars provided and the length of the free end of the steel bars need to meet the various technical requirements for the normal use of the bridge structure and for the bridge to remain firm under earthquake action. In this embodiment The outer contour dimension of the exposed end 22 of the column...

Embodiment 2

[0037] like Figure 3-Figure 4 As shown, another specific embodiment of the combined connection structure and assembly method of the prefabricated bridge pier column and the cap socket and the socket of the present invention includes the following steps:

[0038] Prefabricated column 2, column 2 comprises exposed end 22 and embedded end 23, and several steel bars 24 are embedded in column 2, and steel bar 24 is provided with the free end 25 that stretches out certain length from the bottom end of column embedded end 23; Those skilled in the art should know , the cross-sectional size and reinforcement of the column embedded end 23, the number of steel bars set and the length of the free end of the steel bar need to meet the various technical requirements for the normal use of the bridge structure and the bridge's firmness under earthquake action. In this embodiment, the exposed end 22 of the column The outer contour size is greater than the maximum outer contour size of the emb...

Abstract

The invention discloses a prefabricated pier upright column, cushion cap spigot and insertion groove combined connection structure which comprises a prefabricated upright column and a cushion cap. The upright column comprises an exposed end and an embedded end, a plurality of steel ribs are embedded in the upright column, and the steel ribs extend from the bottom end of the upright column by a certain length to form free ends; an upright column installation hole groove is formed in the vertical direction of the cushion cap, and a plurality of steel rib insertion grooves are formed in the bottom of the upright column installation hole groove; the section shape and the size of the upright installation hole groove are matched with the section shape and the size of the embedded end of the upright column so that the embedded end of the upright column can be embedded into the upright column installation hole groove, and the number, the setting positions and the depths of the steel rib insertion grooves are matched with the number, the setting positions and the lengths of the free ends of the steel ribs so that the free ends of the steel ribs can be embedded in the steel rib insertion grooves. The embedded and fixed connection strength between the upright column and the cushion cap are enhanced in the mode that the number of the steel ribs extend from the bottom of the upright column is increased and the steel ribs are matched and connected with the steel rib insertion grooves of the cushion cap so that increase of the thickness of the cushion cap can be avoided when the section area of the upright column is large, bridge manufacturing materials are saved, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge prefabricated bridge pier column and socket-type connection structure and an assembly method thereof. Background technique [0002] In the prior art, for the assembly of prefabricated pier columns and caps of bridge structures, pre-embedded sleeves, pre-embedded metal bellows and prestressed steel strands are usually used in the columns or caps, and then the connection in the caps or columns Precise positioning and socketing of steel bars Three types of splicing modes for embedded parts; In addition, there is also a splicing method in which a section of column is prefabricated on the cap at the same time, and a section of cast-in-place section is set between this column and the upper column to connect the prefabricated pier and the cap as a whole . [0003] Since the above three commonly used splicing modes of embedded parts need to embed a large number of e...
