The purpose of this utility model is achieved in that a kind of U ribs of steel box girder welded construction, it comprises U-shaped rib body, described U-shaped rib body bottom is provided with base plate, riser is connected with on the upside of the middle part of described base plate, the upper end of described riser is connected with top board, the upside at the two ends, left and right of described base plate is all connected with web, the upper end of described web is connected with end plate, the upper end of described end plate is connected with arc, the top of described arc is connected with top board, gap is provided with between the outside of described arc and the downside of top board, on the downside of described top board, the right side of gap is connected with swash plate, the lower end of described swash plate is connected with transverse slat, the end of described transverse slat is connected with the outside of end plate.

The thickness of described arc, end plate, web plate and back plate is for distribute from big to small.

Angle between described swash plate and transverse slat is obtuse angle.

Described base plate, web, end plate and arc are formed in one structure.

Described riser is rectangular configuration.

Angle between described arc and top board is 40 0-50 0between.

The beneficial effects of the utility model: be arc plate structure between U-shaped rib and top board, and form gap, weld from opening position when welding, increase effectively bonding area, promote stability in use and the durability of U-shaped rib, auxiliary fixing structure is made up of swash plate and transverse slat, the end of transverse slat is connected on end plate, improve U-shaped rib and the steadiness be connected between top board, the riser of the inside of U-shaped rib connects between the bottom panel and top panel, strengthen the structural stability of U-shaped rib, arc, end plate, web, the thickness of base plate is for distribute from big to small, reduce the use amount of steel, provide cost savings, the utility model has applied widely in a word, structure is simple, security and stability is high, lower-cost advantage.

Accompanying drawing explanation

Fig. 1 is the welded structural representation of a kind of U ribs of steel box girder of the utility model.

Fig. 2 is a kind of U ribs of steel box girder welded A place of the utility model enlarged drawing.

In figure: 1, U-shaped rib body 2, end plate 3, riser 4, top board 5, swash plate 6, transverse slat 7, web 8, base plate 9, arc 10, gap.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further.

Embodiment 1

As depicted in figs. 1 and 2, a kind of U ribs of steel box girder welded construction, it comprises U-shaped rib body 1, described U-shaped rib body 1 bottom is provided with base plate 8, riser 3 is connected with on the upside of the middle part of described base plate 8, the upper end of described riser 3 is connected with top board 4, the upside at the two ends, left and right of described base plate 8 is all connected with web 7, the upper end of described web 7 is connected with end plate 2, the upper end of described end plate 2 is connected with arc 9, the top of described arc 9 is connected with top board 4, gap 10 is provided with between the outside of described arc 9 and the downside of top board 4, on the downside of described top board 4, the right side of gap 10 is connected with swash plate 5, the lower end of described swash plate 5 is connected with transverse slat 6, the end of described transverse slat 6 is connected with the outside of end plate 2.
