Easily there is different degrees of function and structure disease, hinge seam concrete defect to the concrete hollow slab bridge for strengthening bridge deck pavement
Sunken, broken, long section comes off, simultaneously because the concrete hollow slab bridge construction method with laterally reinforcement bridge deck pavement is not
When hinge slit width degree is much larger than the hinge slit width degree of design between the hollow slab girder of practice of construction, and after operation a period of time, hinge stitches easily to go out
Existing disease, causes bridge lateral transmission force property to fail, and bridge floor is easy to the longitudinal crack for occurring along hinge seam, influence hollow slab bridge
Normally use, the step by step tray because of single slab bearing is likely to occur when serious and is destroyed.
Accordingly, it would be desirable to which a kind of have the concrete hollow slab bridge for laterally strengthening bridge deck pavement, improving has laterally reinforcement
The horizontal overall structure performance of the concrete hollow slab bridge of bridge deck pavement, it is to avoid single slab bearing, extends bridge service life, prevents
Only there is longitudinal crack in bridge floor.
The content of the invention
In view of this, it is an object of the invention to provide a kind of concrete core slab for having and laterally strengthening bridge deck pavement
Bridge, improves the horizontal overall structure performance with the concrete hollow slab bridge for laterally strengthening bridge deck pavement, it is to avoid single slab bearing,
Extend bridge service life, prevent bridge floor from longitudinal crack occur.
The present invention's has the concrete hollow slab bridge for laterally strengthening bridge deck pavement, including arranged side by side by many hollow slab girders
The bridge floor beam for composition of arranging and the reinforced pave-load layer of transverse direction for being arranged at the bridge floor top surface of the beam；The reinforced pave-load layer of transverse direction
Including corresponding the multistage steel plate being layed on the hollow slab girder, the sliding layer being supported on the steel plate and being layed in
Bitumen layer on the sliding layer；Interfixed between the steel plate and corresponding bridge floor beam, and adjacent two sections of steel plates it
Between connect to transmit transverse load by connector；
Further, the steel plate is fixed on corresponding bridge floor beam by screw rod, and the connector is connecting plate；Institute
Hinge sew on side of the connecting plate between adjacent hollow plate-girder is stated, the screw rod of hinge seam both sides passes through the connecting plate；
Further, the connecting plate is provided with the waist-shaped hole transversely set；The screw rod passes through institute by the waist-shaped hole
State steel plate；
Further, elastomer block is provided between adjacent two steel plate；
Further, the hollow slab girder is provided with groove relative to the side of another hollow slab girder, the screw rod along perpendicular to
The cell wall of the groove is run through in the direction of bridge floor；
Further, the sliding layer is polyfluortetraethylene plate；
Further, being filled with the longitudinal seam between the adjacent hollow slab girder is used for what the screw rod was protected
Epoxy sealing glue.
The beneficial effects of the invention are as follows：The concrete hollow slab bridge with laterally reinforcement bridge deck pavement of the present invention, it is whole
Body structural strength is high, and the bearing capacity of bridge is strong, and single slab bearing can be avoided by horizontal strengthening of steel bridge, extends bridge service life,
Bridge floor is avoided longitudinal crack occur, its structure simple structure, engineering construction quality easily ensures that stress performance is good, and consolidation effect is bright
It is aobvious, remarkable in economical benefits, beneficial to popularization.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the invention；
The structural representation of the connecting plate of Fig. 2 present invention.
Embodiment
Fig. 1 is structural representation of the invention, as shown in the figure：The mixed of bridge deck pavement is laterally strengthened in having for the present embodiment
Solidifying soil hollow slab bridge, including the bridge floor beam being made up of many hollow slab girder laid out in parallel and the horizontal stroke for being arranged at the bridge floor top surface of the beam
To reinforced pave-load layer；The reinforced pave-load layer of transverse direction includes corresponding the multistage steel plate being layed on the hollow slab girder
2nd, the sliding layer 4 being supported on the steel plate 2 and the bitumen layer being layed on the sliding layer 4；The steel plate 2 and right therewith
Interfixed between the bridge floor beam answered, and connect to transmit transverse load, this implementation by connector between adjacent two sections of steel plates 2
Transverse load between the hollow slab girder of the hollow slab bridge of example can be transmitted by the connector between steel plate 2, overall knot
Structure intensity is high, and the bearing capacity of bridge is strong, and single slab bearing can be avoided by horizontal strengthening of steel bridge, extends bridge service life, it is to avoid
There is longitudinal crack in bridge floor, and its structure simple structure, engineering construction quality easily ensures that stress performance is good, and consolidation effect substantially, is passed through
Help remarkable benefit, beneficial to popularization, in addition, when lateral displacement occurs for hollow slab girder or when expanding with heat and contract with cold, steel plate 2 and bitumen layer it
Between can occur relative slip, it is to avoid there is crack in hollow slab girder displacement in bitumen layer.
