Technical Field
The utility model relates to a steel construction bridge field, especially a road surface structure of steel construction bridge.
Background
Compared with a concrete structure bridge, the steel structure bridge has the advantages of simple and rapid construction, short construction period, light weight of the bridge body, good toughness, good anti-seismic performance, attractive appearance, convenience in disassembly and the like. Steel construction bridge generally adopts steel sheet + concrete pavement road surface bottom + bituminous paving, and high temperature makes the bonding strength between layer and the steel sheet of mating formation reduce, under the load effect of road surface car, causes the lapse between layer and the steel sheet of mating formation easily, consequently, this application has proposed a steel construction bridge's road surface structure, overcomes the above-mentioned problem that exists among the prior art.
SUMMERY OF THE UTILITY MODEL
This patent is in order to overcome above-mentioned problem, the utility model provides a road surface structure of steel construction bridge.
The road surface structure of steel structure bridge in this patent, including steel frame 1, steel bridge face board 2, steel column 3, reinforcing bar net 4, pull ring 5, steel fibre concrete layer 6, resistant pitch layer of waiting. Install steel bridge deck plate 2 in steel structural framework 1 of steel structural bridge, pass through the bolt or weld installation a plurality of steel column 3 on steel bridge deck plate 2 for steel column 3 is covered on steel bridge deck plate 2 according to certain interval. After the steel columns 3 are installed, the reinforcing mesh 4 is installed on the steel bridge deck 2, and the reinforcing mesh 4 is positioned through the steel columns 3 to prevent slippage. The two sides of the reinforcing mesh 4 are connected with the steel structure frame 1 by adopting pull rings 5, and the pull rings 5 can be connected by adopting bolts or welded. A steel fiber concrete layer 6 and a weather-resistant asphalt layer 7 are paved above the reinforcing mesh 4. The road surface is provided with expansion joints 8 in sections. And a closed structure is arranged in the expansion joint 8.
The closed structure comprises a hard rubber layer 9, an elastic rubber layer 10, a rubber cover 11, vertical steel bars 12, transverse steel bars 13 and springs 14. The middle of the lower portion of the hard rubber layer 9 is provided with a vertical reinforcing steel bar 12, two sides of the vertical reinforcing steel bar 12 are respectively provided with a guide reinforcing steel bar 14, a transverse reinforcing steel bar 13 is arranged on the side of an expansion joint 8 of the pavement structure, the transverse reinforcing steel bar 13 corresponds to the guide reinforcing steel bar 14 in position, and a spring 15 is sleeved outside the transverse reinforcing steel bar 13 and the guide reinforcing steel bar 14. An elastic rubber layer 10 and a rubber cover 11 are arranged above the hard rubber layer 9.
Through set up the steel column on steel bridge deck plate, can restrict the removal of concrete surface course, through set up the spring in the expansion joint, can cushion 8 expansion pressure in expansion joint, also can restrict the pavement structure and take place to remove, improved the stability on steel structure bridge road surface.
