Abstract
The utility model discloses a kind of railroad bridge rotator construction assembling beam body pier base, including vertically arranged Reinforced Concrete Pier Column, the top horizontal of Reinforced Concrete Pier Column is provided with bent cap, bent cap, which is equipped with, turns to blind hole, it turns in blind hole and lays rotation support column, it uses the utility model has the beneficial effects that since rotation support column is to be placed in turn in blind hole with revocable scheme, it can be pulled out after construction, bent cap plays rigid support to beam body, is conducive to the stability for promoting the beam body of installation.
Description
Technical field
The utility model relates to railroad bridge technical fields, and in particular to a kind of railroad bridge rotator construction assembling beam body
Pier base.
Background technique
With the quick raising of national economy level, communication is also greatly developed therewith.Due to some landform or existing
The influence of means of transportation, Bridge Rotation Construction Technique have been more and more widely used in bridge construction.Compared with traditional bridge, turn
The construction technology of body bridge have do not interfere traffic, uninterrupted navigation, can across zanjon river, can be across the spy of traffic bound road
Point, and construct quickly, economical and efficient.Since swivel weight is big, rotational angle is big, beam body is longer, bridge type is complicated, the master of bridge
How tower, Main beam linearity, stay cable force and swivel weight are accurately positioned, and smooth rotation is the difficult point in swivel, and traditional turns
Body bridge is typically all to rotate bridge by flexural pivot by installing flexural pivot on bridge crouching seat, flexural pivot after rotateing in place
For a part for turning bridge support base, bridge is mounted on rotatable component, can produce to the stability of bridge for a long time
Raw adverse effect.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of railroad bridge rotator construction assembling beam body pier base.
Technical solution is as follows: a kind of railroad bridge rotator construction assembling beam body pier base, key are: including vertically setting
The Reinforced Concrete Pier Column set, the top horizontal of the Reinforced Concrete Pier Column are provided with bent cap, and it is blind that the bent cap is equipped with steering
Rotation support column is laid in the steering blind hole in hole.Beam body is equipped with crossover port by adopting the above technical scheme, in rotation support column
After the lifting device and rotating device of upper installation rotation beam body, beam body is lifted using lifting device, utilizes rotating device pair
Beam body turns to, and turns in place rear beam body and falls on bent cap, and bent cap plays hard support to beam body, extracts rotation support column later and is
It can.
As preferred: shoulder guard is arranged in the bottom hole of above-mentioned steering blind hole, and the rotation support column is placed in the protection steel
On plate.The gravity that support column passes over can will be rotated using program shoulder guard to evenly spread on bent cap, avoid bent cap
Stress is concentrated, and is played a protective role to bent cap.
Above-mentioned rotation support column and the protective layer turned between blind hole equipped with rigidity.Protective layer can in rotary course
It plays a protective role to bent cap.
Above-mentioned rotation support column is cylindroid or square column.Rotating support column when rotating beam body using the program will not be with
Beam body turns to together.
The material of above-mentioned rotation support column is solid steel column.Be conducive to be promoted the load-bearing energy of rotation support column using this scheme
Power.
The upper surface of above-mentioned bent cap is equipped with the guide slide of annular, and the rotation support column is located on the inside of the guide slide.
The bottom of above-mentioned Reinforced Concrete Pier Column is provided with the cushion cap of strip, and the cushion cap is parallel with the bent cap, described
The length of cushion cap is more than or equal to the length of the bent cap.Ensured around cushion cap using the program when pouring beam body on roadbed, is held
The position that platform occupies is beam body lifting hole, it is ensured that beam body can pass through bent cap when going up and down.
The 1/5-1/7 with a thickness of the rotation support column height of above-mentioned shoulder guard.
The utility model has the advantages that using the utility model has the beneficial effects that since rotation support column is with the placement of revocable scheme
It is turning in blind hole, can be pulled out after construction, bent cap plays rigid support to beam body, is conducive to the beam body for promoting installation
Stability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the A-A ' cross-sectional view of Fig. 1.
Specific embodiment
Below with reference to embodiment and attached drawing, the utility model is described in further detail.
As shown in Figure 1-3, a kind of railroad bridge rotator construction assembling beam body pier base, including vertically arranged reinforced concrete
Knoll column 1, the top horizontal of the Reinforced Concrete Pier Column 1 are provided with the bent cap 2 of strip, and it is blind that the bent cap 2 is equipped with steering
Rotation support column 3 is laid in hole in the steering blind hole.
The bottom of the Reinforced Concrete Pier Column 1 is provided with the cushion cap 6 of strip, and the cushion cap 6 is parallel with the bent cap 2,
The length of the cushion cap 6 is more than or equal to the length of the bent cap 2, and the rotation support column 3 is solid oval steel column or rectangular
Steel column, the bottom hole for turning to blind hole are arranged shoulder guard 4, the shoulder guard 4 with a thickness of rotation support column 3 height
, the rotation support column 3 is placed on the shoulder guard 4, the rotation support column 3 and the steering blind hole it
Between be equipped with the protective layer 5 of steel, the upper surface of the bent cap 2 is equipped with the guide slide 7 of annular, and the rotation support column 3 is located at
7 inside of guide slide.
When construction, beam body is poured directly about the crouching seat of the utility model, cushion cap 6 is surrounded in beam body and forms a bar shaped
Bent cap relief hole will revolve again in the top installation promotion of rotation support column 3 and rotating device after beam body promotion to certain altitude
Turn, is generally rotated by 90 ° left and right, then puts down beam body, the bent cap relief hole in beam body is become from the direction parallel with bent cap 2
Then rotation support column 3 is extracted so that bent cap 2 be enable to accept beam body in perpendicular direction, take out shoulder guard 4 and prevent
Sheath 5, then to the strip-shaped hole sealing of hole in beam body.
Finally, it should be noted that foregoing description is only the preferred embodiment of the utility model, the common skill of this field
Art personnel are under the enlightenment of the utility model, under the premise of without prejudice to the utility model aims and claim, can make
Multiple similar expressions, such transformation are each fallen within the protection scope of the utility model.
