AI Technical Summary

Problems solved by technology

The price of grouting sleeves and special grouting materials is relatively high, and the grouting construction is relatively cumbersome. With the increase of the connection surface, the price of connection materials increases and the construction time is prolonged, which seriously limits the project of segmental assembled piers using this method Value

Embodiment 1

[0066] A structural connection section of a section assembled pier column, comprising a male section 1 and a female section 2 .

[0067] Such as figure 1 As shown, the male segment 1 includes a first body 10, the first body 10 is a reinforced concrete structure, and the body 10 is provided with stirrups. The first body 10 is provided with a first assembly end 11 and a second assembly end 12 , and the first assembly end 11 and the second assembly end 12 are used for assembling with the female segment 2 . Several first longitudinal ribs 13 are also provided in the first body 10, each of the first longitudinal ribs 13 runs through the first body 10, and extends from the first assembly end 11 and the second assembly end 12 respectively. out. In this embodiment, preferably, the length of the first longitudinal rib 13 protruding from the first assembling end 11 is equal to the length protruding from the second assembling end 12 . Such as Figure 2-Figure 3 As shown, the male sec...

Embodiment 2

[0076] A method for designing a structural connection section of a segmentally fabricated pier column, comprising the following steps:

[0077] Step 1: Design the structural connection section of the section-fabricated pier column into two types of standard sections, namely male section 1 and female section 2;

[0078] Step 2: Design the public segment 1, including calculating the cross-sectional size, height, volume reinforcement ratio of the stirrups of the public segment 1, the number, cross-sectional size, and position of the first longitudinal reinforcement 13, and the extension of the first longitudinal reinforcement 13 The length of the first assembling end 11 and the second assembling end 12;

[0079] Step 3: Design the female segment 2, including determining the height of the female segment 2 according to the sum of the lengths of the first longitudinal rib 13 protruding from the first assembly end 11 and the second assembly end 12; according to the number of the firs...

Embodiment 3

[0083] Such as Figure 13-Figure 14 As shown, a construction method for the structural connection section of a segmental fabricated pier column, comprising the following steps:

[0084] Step 1: After the male segment 1 has been assembled, wet the first longitudinal rib 13 of the male segment 1 with tap water, and apply the adhesive material 5 to the first assembly end 11 of the assembled male segment 1, moisten and Level the chiseled surface, and ensure that the shear key A 3 of the male segment 1 is filled with an adhesive material 5 (high-strength mortar, self-leveling concrete, etc.) that is at least a quarter of the volume of the groove. Next, wet the through hole 23 of the female segment 2 to be assembled with tap water first, hoist the female segment 2 above the male segment 1, and align the fourth assembly end 22 of the female segment 2 with the male segment 1, assemble the through hole 23 of the female segment 2 to the first longitudinal rib 13 of the male segment 1, ...

Abstract

The invention discloses a section assembly type pier column structure connection section and a design method and a construction method thereof. The structure connecting section comprises a male section and a female section, wherein the male section comprises a first body, a first splicing end and a second splicing end are arranged on the first body, a plurality of first longitudinal ribs are further arranged in the first body, each first longitudinal rib penetrates through the first body and extends out from the first splicing end and the second splicing end correspondingly, the female section comprises a second body, a third splicing end and a fourth splicing end are arranged on the second body, the height of the second body is greater than or equal to the sum of the lengths of the portions, extending out of the first splicing end and the second splicing end, of each first longitudinal rib, a plurality of through holes are further formed in the second body, the number, the position and the cross section size of the through holes are matched with those of the first longitudinal ribs, shear keys A are arranged at the first splicing end and the third splicing end, shear keys B are arranged at the second splicing end and the fourth splicing end, the shear keys A and the shear keys B are matched, and grooves with the same shape and size are formed in all splicing ends.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a structural connection section of a section-assembled pier column and a design method and a construction method thereof. Background technique [0002] In municipal traffic engineering and railway engineering, the design, manufacture and construction of segmental prefabricated beams have been relatively mature. The cast-in-place construction method leads to a long construction period for the whole bridge, which is one of the important obstacles to the realization of the prefabricated full bridge, which limits the advantages of the prefabricated structure. The integral prefabricated pier column is an engineering application form to realize the prefabricated assembly of the pier column, but this method has prominent problems such as large component weight, large size and volume, and restrictions on transportation and hoisting. Segmentally prefabricated pier column (PSBC...
