Description
Technical field
The utility model belongs to bridge construction field, is related to a kind of uniform load transfer device of bearing for having gradient precast beam, can
Avoid the occurrence of seat empty and the serious non-uniform phenomenon of stress.
Background technology
At present, in middle or small bridge beam, adopt high elastic rubber sheet-type support more, its planform generally circular in cross section or
Rectangle.The bridge pad of this form is for conventional orthogonal, horizontal plate-girder, a kind of preferable form of can yet be regarded as.In recent years, with
The high speed development of urban road and highway, substantial amounts of curved bridge, slope bridge is occurred in that, sometimes bridge bottom surface is more than
There is the gradient in direction across bridge, in vertical bridge to there is also the gradient.This brings great difficulty to the installation of bearing.Even level is propped up
Seat, in 4 bearings of one piece of prefabricated board, it would still be possible to there is the bearing for coming to nothing.In view of construction error, it is impossible in the pre- of beam slab
When processed, make each Bearing Seat Force uniform by the thickness or angle of inclination of the embedded board of every piece of prefabricated board of adjustment.Mishandling, then
The pressure distribution that beam slab passes to pier by bridge pad is just very uneven, and the bias of generation causes that bridge pad is monolateral to be received
Power, i.e. bridge pad have that stress is overweight, the phenomenon that another side does not almost stress.
Requirement that laminated rubber bearing can only horizontal positioned stress, therefore by adjust base-plate method not
A difficult problem installed by the bearing of the beam slab that can solve very well to there is slope.Utility model as Patent No. ZL01239234.0 is disclosed
A kind of adjustable basin type bridge pedestal, is provided with basin ring on its lower seat board, and the basin ring is by adjustable screw mechanism and lower seat board
Connection.After rotary screw mechanism, the absolute altitude of bearing can be adjusted by increaseing or decreasing the quantity of steel pad.The device is applied to plate
During formula rubber support, the situation effect to bridge bottom surface level is preferable, and the precast beam that all there is inclination to both direction is then incompetent
For power.
Although certain adjustment effect can be played using the coronal circular plate rubber bearing of Intermediate Gray projection, when top is tied
When the beam body gradient of structure is larger, monolateral stress can not still obtain basic solution.The invention of Publication No. CN105239502A is special
Profit discloses a kind of bridge pad uniform load transfer device and its installation method.Its stressed regulating device is steel plate spherical crown polymer
Mortar structure, because construction error, the size of wherein spherical crown are difficult to meet field requirement, increased installation difficulty.Publication No.
The patent of invention of CN101220578A discloses a kind of regulatable supporter, by disposing a press expansion body on bearing, then
Curable liquid is injected into press expansion body, so as to more ideally solve the problems, such as that beam body has slope.Which dilates change
Body vertical and lateral dimension during press-in curable liquid changes, a generally flexible pocket.Because of press expansion body
Typically it is made by rubber, needs custom-made, and aging with rubber, the absolute altitude of beam slab can change, because of each rubber
The degree of aging of colloid is not necessarily identical, and portion of standoff still occurs unbalance stress and phenomenon of coming to nothing.In addition, which dilates change
Body widthwise size after deformation and size wayward.
Content of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art and problem, there is provided one kind has slope
The uniform load transfer device of bearing of degree precast beam.The device is by upper padding plate, metal bellows, sealing ring and by upper padding plate
Bolt, the grout outlet for penetrating inboard aperture and pulp-inlet pipe composition that apertura lateralis is screwed in, form a sky with beam body lower surface after installation
Chamber, the cavity can be pressed into high-strength mortar by pulp-inlet pipe for closed in addition to the pore of grout outlet and pulp-inlet pipe.Bellows makes this
Device vertically scalable, so as to full-bridge using a kind of specification the device.The top and bottom of bellows respectively with sealing ring
Paste closely with upper padding plate.When installing the device, precession bolt, makes sealing ring closely close with the embedded board of beam body bottom surface upwards
Patch.Though metal bellows in the installation process of the device can longitudinal extension, after being bolted, shape is fixed, pressure
During slurry lateral dimension also change little, negligible.The device is easy to building site to make, easy for installation.
Further, the material of sealing ring is metal.The sealing ring rigidity of metal is larger, acts in the pressure of lower square bolt
Under, it can be ensured that the adhesive glue during mud jacking between sealing ring and embedded board does not ftracture.
The utility model simple structure, is easy to field fabrication, easy for installation, is suitable for acclive prefabricated beam support and installs,
Avoid the occurrence of seat empty and the serious non-uniform phenomenon of stress.Just by the device fix in position before mud jacking, during mud jacking
Also without observable deformation, for designing predetermined shape after slurry solidification in cavity.

Specific embodiment
Specific embodiment of the utility model is the following is, and combines accompanying drawing and the technical solution of the utility model is retouched
State, but the utility model is not limited to these embodiments.
Embodiment one
The corresponding schematic diagram of the present embodiment is shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4.Device in the present embodiment mainly includes upper padding plate
3rd, metal bellows 2 is connected with upper padding plate 3 and sealing ring 1 by epoxide-resin glue with sealing ring 1, metal bellows 2, so as to
Ensure that impermeability and the intensity of seam.The size of their threes matches.The edge of upper padding plate 3 is to the edge of rubber support 6
Minimum dimension is 3 centimeters.The thickness of upper padding plate 3 and sealing ring 1 is 1 centimeter.In compressive state, metal bellows 2 is formed
The wall thickness of cylinder is 1 centimeter, and the diameter of inboard aperture 5 and apertura lateralis 4 is 1 centimeter, and inboard aperture 5 and apertura lateralis 4 all have internal thread.
Bridge beam body 16 has prefabricated beam sides 11, precast beam end face 12 and prefabricated soffit 10, is embedded with pre-buried on prefabricated soffit 10
Plate 9.During the beam body 16 that builds a bridge, in each 6 one height adjustable temporary support of other placement of rubber support.Adjustment bridge beam body
After 16 horizontal level, it is placed on temporary support, temporary support is adjusted, makes the absolute altitude at the control point of bridge beam body 16
Meet design requirement.
Lower bolster 7, and strictly placement design attitude placement rubber support 6 is disposed on pinner 8, and guarantees its level.Will
Device of the present utility model is installed on rubber support 6, it is ensured that upper padding plate 3 is symmetrical in rubber support 6, inboard aperture 5 and apertura lateralis 4
Expose.In 1 upper surface uniform application epoxide-resin glue of sealing ring.Outwards side opening 4 screws in bolt 13 from bottom to top, screws in successively each
Bolt 13, it is to avoid sealing ring 1 produces excessive inclination, until the epoxide-resin glue contact embedded board 9 on sealing ring 1, and extrude
Colloid more uniform till.
After epoxy resin adhesive curing and after reaching the intensity of regulation, it is installed into grout outlet 14 into inboard aperture 5 respectively and enters slurry
Pipe 15.The length that pulp-inlet pipe 15 is screwed in is slightly larger than 1 centimeter, and 14 top of grout outlet releases 1 centimeter after arriving to embedded board 9 again.Can lead to
Cross pulp-inlet pipe 15 and high-strength mortar is slowly pressed into, when grout outlet 14 has slurries to flow out, then slowly grout outlet 14 is closed, in this mistake
Cheng Zhong, quick pressure injection high-strength mortar.Closing grout outlet 14 and pulp-inlet pipe 15, to be solidified, temporary support is removed, that is, completes bearing
Install.
