Abstract
This utility model relates to a kind of polyurethane steel box girder bridge floor paving structure, this paving structure includes steel box-girder top board, it is characterized in that, be upwards sequentially provided with water-proof tack coat, polyurethane sheet, epoxy bond layer and epoxy asphalt concrete layer from described steel box-girder top board.Owing to this utility model is additionally arranged polyurethane sheet between epoxy bond layer and water-proof tack coat, therefore there is stability height, the advantage of good endurance.
Description
Technical field
This utility model relates to the bridge floor of bridge, is specifically related to the paving structure of steel box girder bridge face.
Background technology
Bituminous concrete is the bridge deck pavement material commonly used at present, but due to asphalt concrete pavement layer and bridge floor
Plate interlayer adhesion is poor, so under Driving Loading repeatedly, pave-load layer can produce relative displacement generation failure by shear, and produces
Give birth to the passage of asphalt mixture surfacing, gather around the diseases such as bag.Under low temperature, pave-load layer is the most hardening, becomes fragile, and makes to produce between pave-load layer and steel plate to take off
Layer disease, pave-load layer also can produce vertical under load action, and Transverse Cracks, globality and resistance to shock are poor.
Double-layer asphalt mastic-broken stone mixture (SMA) although mat formation can improve asphalt mixture surfacing passage, gather around the disease of bag
Problem, but work of mating formation weighs big, increases bridge deck pavement deadweight, particularly can not improve the delamination between pave-load layer and steel plate sick
Evil.
Additionally, the most no matter use which kind of material to carry out mating formation and will arrange between floorings and pave-load layer
Water-proof tack coat, and water-proof tack coat is during bituminous mixture laying, can be able to be subject to when rolling by thermal shock simultaneously
That gathers materials punctures, it is also possible to be contaminated, and waterproof action is substantially reduced, simultaneously water-proof tack coat and the adhesion strength of floorings
To significantly reduce.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of polyurethane steel box girder bridge floor paving structure, this knot of mating formation
Structure has stability height, the advantage of good endurance.
A kind of polyurethane steel box girder bridge floor paving structure, this paving structure includes steel box-girder top board, it is characterised in that from institute
The steel box-girder top board stated upwards is sequentially provided with water-proof tack coat, polyurethane sheet, epoxy bond layer and epoxy asphalt concrete
Layer.
In above-mentioned deck installation structure, described water-proof tack coat is by the polyurethane adhesive being coated on steel box-girder top board
Constitute.
In above-mentioned deck installation structure, the thickness of described water-proof tack coat is 0.25-0.4mm；Described polyurethane sheet
Thickness be 5-10mm；The thickness of described epoxy bond layer is 0.5-0.7mm；Described epoxy asphalt concrete layer
Thickness is 4-5cm.
This utility model polyurethane steel box girder bridge floor paving structure increases between epoxy bond layer and water-proof tack coat
If polyurethane sheet, therefore compared with prior art there is following beneficial effect:
1, make full use of that the non-deformability of polyurethane sheet is strong and good springiness, good toughness characteristic, effectively protect under it
The water-proof tack coat in face will not cause tear, even interlayer slip delamination in long-term roller compaction process, significantly improves anti-
Waterproof and the etch-proof effect of water tack coat；
2, the heat-proof quality that polyurethane sheet is excellent is utilized, it is to avoid the epoxy bond layer process that pave is to water-proof tack coat
Thermal shock so that it is that is gathered materials when rolling punctures, and then it causes waterproof and anticorrosion ability to decline；Simultaneously as it is poly-
Urethane plate has excellent heat-proof quality, it is possible to ensure that upper strata bituminous concrete is not affected by steel box-girder temperature.
Accompanying drawing explanation
Fig. 1 is the section structure schematic diagram of polyurethane steel box girder bridge floor paving structure described in the utility model.
Detailed description of the invention
Seeing in Fig. 1, this example, described polyurethane steel box girder bridge floor paving structure is wrapped the most successively from steel box-girder top board 1
Include water-proof tack coat 2, polyurethane sheet 3, epoxy bond layer 4 and epoxy asphalt concrete layer 5；Wherein, water-proof tack coat 2 by
The polyurethane adhesive being coated on steel box-girder top board 1 is constituted, and thickness is 0.3mm；The thickness of polyurethane sheet 3 is 7mm；Epoxy
The thickness of resin-bonded layer is 0.6mm；The thickness of epoxy asphalt concrete layer is 4.5cm.
Seeing Fig. 1, the concrete construction method of polyurethane steel box girder bridge floor paving structure described in the utility model is as follows:
(1) bridge surface armor plate processes
By steel box girder bridge top board 1 surfacing, cleaning, pollution-free etc., steel box girder bridge panel is carried out derusting by sandblasting process,
Making its cleannes reach Sa2.5 level, roughness reaches 50～100 μm.
(2) brushing of polyurethane adhesive binding agent
Polyurethane binder host component A and firming agent B component are joined in blender mixed by the mass ratio of 100:20
Close uniformly, then mixed liquor is poured out and be laid on steel box girder bridge panel, then with sawtooth pattern scraper even spread, obtain waterproof viscous
Knot layer 2.
(3) construction of polyurethane sheet
After coating polyurethane binder, pave on steel box girder bridge panel polyurethane sheet 3 immediately, and makes it fill with Steel Bridge Deck
Tap is touched, and then carries out pressing in being coated with polyurethane binder 30 minutes.Pressure need to be more than 0.05MPa, it is ensured that each piece of plate pressure
Power is uniformly and splicing is neat, and the gap between prefabricated polyurethane sheet 3 uses the mode of perfusion liquid polyurethane binder to seal,
To be bonded dose is fully cured and carries out release afterwards.After integral construction, it is carried out quality examination, it is desirable to reach without broken hole, leakage
Spread, disengage, tilt, Buckling phenomenon, it is ensured that its sealing is good.
(4) construction of epoxy bond layer
Deng (generally 7 days) after the complete maintenance well of polyurethane sheet, the most uniformly spray epoxy resin, obtain asphalt mixtures modified by epoxy resin
Fat tack coat 4.
(5) construction of epoxy asphalt concrete
Pave on epoxy bond layer 4～5cm thick epoxy asphalt concretes, re-use paver carry out paving,
Chaser is compacted, and the speed paved is maintained at 4-5 rice/min, after having paved, carries out deck paving non-vibration and repeatedly rolls, make
Each binder course of mating formation interpenetrates, and is compacted form firm epoxy asphalt concrete layer 5.
