As a kind of improvement of the present utility model, the junction on the lower chord tube with width bar offers connecting hole.
By using such scheme, directly width bar can be inserted in lower chord tube by connecting hole, it is convenient subsequently by width bar
It is fixed after being welded with lower chord tube.
As it is of the present utility model it is a kind of improve, the connecting hole is the small taper hole of outer imperial palace, the macropore of the connecting hole
Footpath is more than the external diameter of width bar.
By using such scheme, after in width bar insertion connecting hole, between the outer wall of big nose end and the width bar of connecting hole
Certain gap is left, after width bar is connected with lower chord tube on gap, can to connect more between width bar and lower chord tube
Add firmly.
In summary, the utility model has the advantages that：
1st, two lower chord tubes are achieved a fixed connection by the first connecting tube, real by the second connecting tube between three lower chord tubes
Now it is fixedly connected, after it will wind up pipe and lower chord tube is connected firmly by width bar, continues on three pipes that wind up along its length
Uniformly connected by some transverse beam assemblies, so as to greatly reinforce the overall structural strength of circular arc bridge, improve the peace used
Quan Xing；Width bar between the single lower chord tube and the pipe that winds up is distributed in polyline shaped, adjacent width bar and lower boom or the pipe that winds up
Between can form the triangular structures of multiple stabilizations, ensure that the integrally-built stability of circular arc bridge, improve structural strength；
The caliber of lower chord tube is more than the caliber for the pipe that winds up, it is ensured that there is enough intensity the lower end of circular arc bridge to support its circular arc bridge
Upper end, it ensure that the structural strength of whole bridge；
2nd, transverse beam assembly is in I-shaped main body of cross-beam including cross section, can greatly reduce the weight of whole piece, in crossbeam
The side plate that the both ends of main body set cross section L-shaped can improve the structural strength of main body of cross-beam, can also facilitate crossbeam group
Welding between part and the pipe that winds up, set backing plate to be also convenient for welding in the centre position of main body of cross-beam lower surface, ensure crossbeam group
It is connected firmly between part and the pipe that winds up of centre；Multipair gusset is arranged with the concave face of main body of cross-beam, can be greatly improved
The structural strength of main body of cross-beam, so as to improve the structural strength of whole bridge；
3rd, connecting hole is offered on lower chord tube with the junction of width bar, connecting hole is the small taper hole of outer imperial palace, connecting hole
Large aperture is more than the external diameter of width bar, after in width bar insertion connecting hole, is left between the outer wall of big nose end and the width bar of connecting hole
Certain gap, after width bar is connected with lower chord tube on gap, it can to connect between width bar and lower chord tube more firm
