Specific implementation mode
The specific implementation mode of the present invention is described below, in order to facilitate understanding by those skilled in the art this hair
It is bright, it should be apparent that the present invention is not limited to the ranges of specific implementation mode, for those skilled in the art,
As long as various change is in the spirit and scope of the present invention that the attached claims limit and determine, these variations are aobvious and easy
See, all are using the innovation and creation of present inventive concept in the row of protection.
According to one embodiment of the application, with reference to figure 1- Fig. 7, the Precast Concrete Segmental Bridges bridge pier steel reinforced concrete of this programme connects
Head, including the prefabricated pier 100 of several block concretes, the rectangular cross-section hollow section of concrete prefabricated structure, circular hollow section,
Rectangular solid cross section or circular solids section, the present embodiment select rectangular hollow section to carry out following explanation.
It is embedded with an outside plate 1021 on four side walls of adjacent prefabricated 100 junction of the pier periphery of two block concretes,
An inside steel plate 1022, the side end and level of inside steel plate 1022 and outside plate 1021 are embedded on its four side wall in inside
Steel plate 1031 is aligned, and the upper surface and lower face of adjacent prefabricated 100 junction of pier of two block concretes are embedded with a horizontal steel plate
1031, the inside of horizontal steel plate 1031 is evenly distributed with several shear connectors 1032, and shear connector 1032 is welded in level
On steel plate 1031, and shear connector 1032 be WELDING STUDS, perforated panel shear connector 1032, shaped steel shear connector 1032 or
Reinforcing bar shear connector 1032, for realizing the smooth transmission of axle power.
Wherein, the outside of outside plate 1021 and inside steel plate 1022 is close to that a junction steel plate 1041, outside steel is arranged
Several equally distributed screw shells 1023 are equipped on the outer surface of plate 1021 and inside steel plate 1022, screw shell 1023 is logical
It crosses welding or is threadedly coupled and be fixed on outside plate 1021 and inside steel plate 1022.Junction steel plate 1041 be equipped with it is several with
1042 hole of bolt that 1023 position of screw shell is correspondingly arranged, bolt 1042 pass through 1042 hole of bolt and are inserted into screw shell 1023
In, realize being fixedly connected for junction steel plate 1041 and outside plate 1021 and inside steel plate 1022.
Wherein, 1041 area of junction steel plate be less than 1021 area of outside plate, and on junction steel plate 1041 below with outer steel
The upper following alignment setting of plate.
1041 area of junction steel plate be less than 1022 area of inside steel plate, and on junction steel plate 1041 below with inside steel plate
1022 upper following alignment setting.
Outside plate 1021 and inside steel plate 1022 and the inner surface of horizontal steel plate 1031 are weldingly connected, and concrete prefabricated
Pier 100 constitutes an entirety.
The operation principle of the present embodiment is as follows：
Under load action, bridge pier (concrete prefabricated pier 100) will bear axial compressive force, moment of flexure and shearing, of the invention
Inside steel plate 1022, outside plate 1021 (containing screw shell 1023) and horizontal steel plate 1031 (containing shear connector 1032) welding
For component, entirety is connected as by pre-buried fixed mode with precast pier, forms steel reinforced concrete built-up joint, this work can be pre-
It is completed in factory processed.
Since steel construction and concrete structure being combined so that connection may be used in precast concrete bridge pier segment
Steel plate 1041 is connected as entirety by bolt 1042, forms bridge pier.Axle power can be smooth by the horizontal steel plate 1031 of surfacing
It transmits, avoids partial pressing's problem that at the top of precast pier segment and bottom surface out-of-flatness is brought.When bearing moment of flexure, tension side
Junction steel plate 1041 can bear pulling force, compression-side concrete bearing compressive force, and the couple that the two is constituted can offset moment of flexure.It bears to shear
When, the junction steel plate 1041 of prefabricated subsection connecting pin surrounding can bear to shear, therefore the steel reinforced concrete built-up joint of the present invention is with good
The good ability for bearing axle power, shearing, moment of flexure has and is poured with whole to which the bridge pier segment of precast block is connected as entirety
Build the identical structural behaviour of bridge pier.
The present invention is ingenious by junction steel plate 1041, horizontal steel plate 1031, inside steel plate 1022 and outside plate 1021
Design and cooperation, realize the connection between the prefabricated pier of adjacent concrete 100, and need to only install junction steel plate 1041 at the construction field (site)
Operation is waited with stubborn bolt 1042 is applied, you can realizes dry type connection, the operations such as muscle, grouting, prestressed strand tensioning are worn with traditional
It compares, substantially accelerates construction speed, while avoiding environmental pollution caused by the grouting material trickling that scene grouting is likely to occur,
And junction steel plate 1041, horizontal steel plate 1031, inside steel plate 1022 and outside plate 1021 size can according to bridge pier size and
Shape is processed, and is suitable for the bridge pier of Arbitrary Shape Cross Section and arbitrary dimension.
Although being described in detail to the specific implementation mode of invention in conjunction with attached drawing, should not be construed as to this patent
Protection domain restriction.In range described by claims, those skilled in the art are without creative work
The various modifications and deformation made still belong to the protection domain of this patent.
