Shearing force pins are welded to the steel bridge panel; the steel bridge panel is coated with the epoxy waterproof adhesion coating; a layer of rubble with a single particle diameter is uniformly scattered on the epoxy adhesion layer; then the elastic epoxy mortar transition layer 2-4 cm in thickness is laid on the epoxy adhesion layer, and basalt with a single particle diameter is partially embedded into the elastic epoxy mortar transition layer; the rubble with the single particle diameter is embedded in the elastic epoxy mortar transition layer; finally, the bridge surface epoxy coating layer 5-7 mm in thickness is laid, and the rubble with the single particle diameter is partially embedded in the bridge surface epoxy coating layer. The steel bridge surface pavement structure can effectively lowers the constant load of a bridge, improves the effective loading capacity of a steel box girder bridge, and has the characteristics of sliding prevention, abrasion resistance, high and lower temperature resistance, excellent durability, simple construction, easy maintenance, economic performance, environmental protection and the like.
Description
Technical field
The utility model relates to a kind of steel box girder bridge floor paving structure.
Background technology
Features such as steel box girder bridge face has from heavy and light, and span ability is large, easy construction, economy are remarkable and be applied to more and more widely Large Span Bridges.But steel box girder bridge floor paving system is often easily destroyed within service life, steel box girder bridge floor paving problem restricts steel box girder bridge development always.Paving steel bridge deck generally refers to lays the asphalt surface course that general 10cm is thick on steel plate, under summer high temperature condition, the temperature of Steel Bridge Deck can reach 60-80 DEG C of left and right, at this temperature, bonding layer material easily occurs softening and lost efficacy, and bituminous concrete bad stability, particularly under the effect of traction engine, very easily cause Steel Bridge Deck and asphalt surface course unsticking at vehicular load, bitumen layer produces and passes, gathers around the Common Diseases such as bag, rut, cause the pavement performance variation of bridge floor, when serious, can cause traffic accident.Steel box girder bridge floor paving problem has been expert and the confessed global problem of scholar of this area.
Utility model content
The utility model provides the one layer thickness of mating formation little for the deficiencies in the prior art, have that anti-skid wearable, high-low temperature resistant, waterproof, seepage control, endurance quality excellence, construction are simple, easy care, the bridge deck pavement structure of the features such as economic environmental protection.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of bridge deck pavement structure, fire resistant epoxy water-proof tack coat, elastic epoxy mortar transition zone and bridge floor epoxy coating, described steel bridge deck, fire resistant epoxy water-proof tack coat, elastic epoxy mortar transition zone and bridge floor epoxy coating are mated formation from top to bottom successively, between described elastic epoxy mortar transition zone and steel bridge deck, clench close being connected by shear pin.
Described fire resistant epoxy water-proof tack coat is by high temperature resistant epoxy adhesive and be evenly laid in the rubble that the particle diameter on high temperature resistant epoxy adhesive and described elastic epoxy mortar transition zone joint face is 5-6mm and form, and described rubble accounts for the 50%-80% of described fire resistant epoxy water-proof tack coat superficial area.
Described elastic epoxy mortar transition zone by elastic epoxy mortar and be evenly laid in elastic epoxy mortar and bridge floor epoxy coating joint face on particle diameter be 3-4mm rubble forms, described rubble accounts for the 50%-80% of described elastic epoxy mortar transition zone superficial area.
Described elastic epoxy mortar transition region thickness is 2-4cm, and described epoxy coating thickness is 5-7mm.
Owing to adopting said structure, the utility model compared with prior art has the following advantages:
1, adopt high temperature resistant epoxy adhesive as water-proof tack coat, the cementitiousness of tack coat and steel bridge deck while being increased in summer high temperature, the anti-shearing force at interface while improving high temperature;
2, adopt elastic epoxy mortar transition zone, it can be consistent with the compatibility of deformation of steel bridge deck, and be closely connected with steel bridge deck by shearing pin, in the time of summer high temperature, it can also serve as isolation layer, reduces the serviceability temperature of surperficial epoxy coating, improves the high-temperature behavior of epoxy coating;
3, adopt epoxy coating as surface layer, thickness is 5-7mm, can alleviate the dead load of bridge, improves effective supporting capacity of steel bridge, and anti-skid wearable, road surface comfort level is high, endurance quality is excellent.
Brief description of the drawings
Fig. 1 is the bridge of the embodiment cross section structure schematic diagram of mating formation
In accompanying drawing: 1-bridge floor epoxy coating, 2-elastic epoxy mortar transition zone, 3-shearing pin, 4-fire resistant epoxy water-proof tack coat, 5-steel bridge deck.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.Embodiment
As shown in Figure 1, the bridge deck pavement structure of the present embodiment, Specific construction step is as follows: on steel bridge deck 5, weld shearing pin 3, and steel bridge deck is carried out to processing of rust removing, derusting grade reaches Sa2.5-3 level, roughness reaches 60-100pm, on surface of steel plate after derusting by sandblasting, spray immediately high temperature resistant epoxy adhesive by the standard of 0.4-0.6Kg/m2, this high temperature resistant epoxy adhesive is made up of the component of following mass fraction: epoxy resin 100, thinner 15～20, nano-rubber 10-15, resistant to elevated temperatures curing compound 50～70 compositions of normal temperature cure, high temperature resistant epoxy adhesive performance indications are that the steel to steel tensile shear strength at 80 DEG C is 12MPa, then at the high temperature resistant epoxy adhesive surface small crushed stone that spread particle diameter is 5-6mm immediately, and to make the shared area of small crushed stone and the ratio of the area of epoxy bonds layer be 50%-80%, form fire resistant epoxy water-proof tack coat 4, then build the elastic epoxy mortar transition zone 2 that 3cm is thick in the above, the material of selecting is the JN-RX elastic epoxy mortar that Hunan Goodbond Construction Technic Development Co., Ltd. produces, this elastic epoxy mortar is high tenacity, solvent-free, the three component bonding adhesive taking modified epoxy as chief component, wherein A, B component is respectively elastic epoxy resin and curing compound, C component is special aggregate, there is impact toughness superpower, cementitiousness brilliance, ageing resistance and media-resistant (acid, alkali and water etc.) property excellence, with the advantage such as base material compatibility is good.The small crushed stone that spread particle diameter is 3-4mm in the above before elastic epoxy mortar is uncured, then lay the bridge floor epoxy coating 1 that 6mm is thick, the material that bridge floor epoxy coating is selected is the JN-R bridge floor epoxy coating that Hunan Goodbond Construction Technic Development Co., Ltd. produces, this bridge floor epoxy coating is to be combined by modified epoxy and abrasive aggregates, and thickness is 5-7mm.Modified epoxy has excellent caking property, extensibility, water proofing property, can guarantee that abrasive aggregates is well bonded on basal plane, and abrasive aggregates is the fines of natural basalt fragmentation, has excellent wear-resisting, compressive property.The epoxy coat structure that bi-material is combined to form, quality is light in unit area, rough surface, integral color is black, body structure surface is without seam, good integrity.Thickness is 5-7mm.
