Surface treatment；Make a call to one group by the anchoring hole site of retractor device both sides beam body to be arranged is each to two step surface relevant positions
Hole, each swivel nut of two groups of expansion bolts and screw rod are placed in each corresponding aperture of step surface, and pour into epoxy cement slurry, and two
The uniform brushing in step surface surface adhesive；The each anchor hole of both sides beam body of retractor device is penetrated each corresponding expansion bolt one by one
Screw rod on, then close-fitting is connected with packing ring and nut thereon；Between retractor device both sides beam body and corresponding step surface side
Cavity in fill up High Strength Concrete, retractor device beam body is connected by it with bridge structure thing, simultaneously will be equal for two groups of expansion bolts
Effectively it is locked in inside it.
Contrasted by technical characteristic, the bridge expanssion joint construction process disclosed in above-mentioned document and present patent application are in technology
Relatively big difference is existed on scheme.
Content of the invention
It is an object of the invention to overcoming the deficiencies in the prior art, provide a kind of construction method of bridge expanssion joint, the party
Method using plank sheathing readily removable remove, feature that is capable of circulation, being difficult displacement and surfacing；Customize plank sheathing, peace using live material
It is filled to expansion joint position, compactness and the flatness of expansion joint both sides bituminous concrete not only can be ensured, and do not result in
Sandy soil, debris etc. leak in expansion joint, be a kind of efficiently, reliability, energy-conservation, the construction method of low cost.
The solution of the present invention is achieved in that
A kind of construction method of bridge expanssion joint, step is as follows:
Step one, before science of bridge building abutment concreting, in longitudinal direction or the horizontal stroke of the pre-buried bridge expanssion joint in abutment top
To embedded ribs；
Step 2, make template assembly, the width of this template assembly is wide with expansion joint, the height of template assembly with substantially
Road surface is contour；
Step 3, template assembly is placed on the embedded ribs in expansion joint, template assembly lower surface be supported on beam-ends and
On abutment, the upper surface of template assembly is flushed with basic road surface, and assembly tightly consolidates；
Step 4, in basic road surface and template assembly top asphalt concrete grinding compacting；
Step 5, along template assembly arranged on left and right sides side cutting bituminous concrete and counter open, taking-up template assembly；
Other reinforcing bars in step 6, colligation expansion joint, and welding expansion joint shaped steel on reinforcing bar；
Plug-in mounting cystosepiment in step 7, the gap being formed between the shaped steel of expansion joint, then pours coagulation into expansion joint
Soil, completes expansion joint and all constructs.
And, described template assembly includes template and the lumps of wood of rectangular configuration, parallel longitudinal of the lower surface of described template
Every the multiple lumps of wood of installation.
And, the template size of described template assembly is 75cm × 100cm.
And, in step 4, before asphalt concrete, smear one layer of oils and fats in template assembly top surface.
Advantages of the present invention and good effect are:
The present invention utilizes existing construction material, draw materials easily, construction cost low, and process is simple, speed of application are fast,
Bad utilization can be followed after template assembly dismounting；This method easy construction, quick, not only can ensure expansion joint in work progress
Do not filled by sandy soil debris, and it is flat to can ensure that expansion joint is connected with the asphalt concrete pavement of laying after the completion of constructing
Whole degree, the present invention suitably promotes, and has a extensive future.
