Abstract
The utility model relates to a continuous steel box girder for reinforcing a soleplate on a supporting point. On the supporting point of the continuous steel box girder, the upper edge of a bridge is strained, the lower edge is pressed, the thickness of a large steel plate needs to be increased in order to prevent the local flexion of the structure, but the steel consumption of the whole bridge is increased. A longitudinal reinforced rib is respectively welded on the inner side of each of a top plate, a soleplate and webs on two sides, a shear nail is arranged on a soleplate area on the supporting point, and C50 shrinkage-free concrete is filled; and the shear nail is vertically welded on the inner side of the soleplate, the inner side bottom of the web and the longitudinal reinforced rib of the soleplate. The C50 shrinkage-free concrete is filled on the soleplate, so that the soleplate on the lower edge of the bridge is reasonably integrated with the concrete to be stressed collectively, the flexion instability problem of the steel plate on the lower edge can be solved, the thickness of the steel plate can be effectively reduced, and the consumption of the steel for the whole bridge can be reduced; the stress on a supporting seat can be effectively scattered, so that the stress of the steel plate is uniform and reasonable; and the steel box girder is used as a support, no template is needed, and simplicity in operation can be realized when the continuous steel box girder is under construction.
Description
Technical field
the utility model belongs to bridge construction technical field of buildings, is specifically related to the Steel Continuous Box beam of a kind of fulcrum place jacking of floor.
Background technology
At Steel Continuous Box Liang Zhidianchu, bridge upper limb tension, lower edge pressurized.Steel can be given full play to material property under tension state; And at pressured state, concrete can be given full play to material property compared with steel.Near Steel Continuous Box beam fulcrum, bottom flange compressive stress is larger, and lower edge base plate is thinner, and cripling easily occurs steel plate.Generally, in order to make structure that cripling not occur, can strengthen steel plate thickness, but increase the steel using amount of full-bridge.
Summary of the invention
The purpose of this utility model is to provide a kind of Steel Continuous Box beam that can effectively improve the fulcrum place jacking of floor of Steel Continuous Box beam fulcrum place local compression performance.
The technical scheme that the utility model adopts is:
A Steel Continuous Box beam for fulcrum place jacking of floor, comprises the web of top board, base plate and both sides, and each plate inner side is all welded with longitudinal stiffener, and top board both sides are extended with the edge of a wing, it is characterized in that:
The baseplate zone that is positioned at fulcrum place arranges WELDING STUDS, and pours into C50 non-shrinkage concrete.
Described WELDING STUDS vertical welding is on the bottom and base plate longitudinal stiffener of base plate inner side, web inner side.
The utlity model has following advantage:
1), in conjunction with the loading characteristic of steel case beam, steel and concrete material property have been given full play to.
2) reduced fulcrum place steel using amount.
Due to cross section lower edge pressurized, in order to prevent steel plate flexing unstability under larger compressive stress, way is for strengthening corresponding position steel plate thickness conventionally, and this certainly will increase steel using amount.The utility model by filling C50 non-shrinkage concrete on base plate, lower edge base plate and concrete are organically integrated, and jointly stressed, the flexing destabilization problems of lower edge steel plate is resolved, effectively reduce steel plate thickness, thereby reduced the girder steel of using of full-bridge.
3) effectively improve bearing place stress distribution.
Near bearing, due to the supporting role of bearing, can be to the local complicated stress concentration phenomenon of structure generation, this is very disadvantageous to the stressed of steel, near subplate bearer, fill with concrete, can effectively spread bearing stress, the stressed of steel plate is tending towards evenly rationally.
4) construction method is simple.
Owing to having steel case beam as support, without template is set, simple to operate during construction.

Fig. 2 is cross-sectional drawing.
Fig. 3 is layout plan.
In figure, 1-top board, 2-base plate, 3-web, 4-diaphragm, 5-C50 non-shrinkage concrete, 6-WELDING STUDS, 7-top board longitudinal stiffener, 8-web longitudinal stiffener, 9-base plate longitudinal stiffener.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
The Steel Continuous Box beam of a kind of fulcrum place jacking of floor that the utility model is related, during Gang Xiang beam factory section assembling, soldered WELDING STUDS on bridge fulcrum place beam section base plate and longitudinal stiffener, after steel box girder construction completes, by entering Ren Dong, enter case beam inside, pour into the C50 of this place non-shrinkage concrete.
Concrete structure is:
The web 3 that is provided with top board 1, base plate 2 and both sides, forms closed rectangular enclosure.Each plate inner side is all welded with longitudinal stiffener, and top board 1 both sides are extended with the edge of a wing.Web 3 inner sides are provided with web longitudinal stiffener 8, are plate shape stiffening rib; Base plate 2 inner sides are provided with base plate longitudinal stiffener 9, are T-shaped stiffening rib; Top board 1 inner side is provided with top board longitudinal stiffener 7, is T-shaped stiffening rib; Top board 1 inner side of the position corresponding with track is provided with large vertical rib, is T-shaped stiffening rib.All stiffening ribs adopt welding manner to be connected with steel case beam inner side.In the hollow cavity of Steel Continuous Box beam, ring arranges multiple tracks diaphragm 4, interval 2m week.Be positioned at the base plate 2 region division WELDING STUDS 6 at fulcrum place, and pour into C50 non-shrinkage concrete 5, lower edge base plate and concrete are organically integrated, jointly stressed.Wherein, WELDING STUDS 6 vertical weldings are on the bottom and base plate longitudinal stiffener 9 of base plate 2 inner sides, web 3 inner sides.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model manual, is claim of the present utility model and contains.
