In groove, the size of tubing bore is directly related to the span and intensity of entire arch bridge, but arc-shaped wave card is recessed in practical application
The size of slot limits the size of concrete plug bore, is not suitable for large span and the construction of high buried depth arch bridge.
Utility model content
Purpose of utility model：The purpose of this utility model is to provide a kind of assembled formed steel construction arch bridge, to improve intensity
While avoid the limitation of groove size, adapt to the construction under large span and high Conditions of Buried Depth.
Technical solution：Assembled formed steel construction arch bridge provided by the utility model, including arc-shaped wave card, shaped steel, type
Steel sets composition assembled unit in arc-shaped wave card groove parallel beneath, and assembled unit splices shape along arch bridge length and width direction
Into bow member, the ridge orientation of arc-shaped wave card is vertical with arch bridge width, and arc-shaped wave card is with shaped steel by welding or being bolted
For an entirety.
Shaped steel is arranged at intervals in arc-shaped wave card groove parallel beneath；Shaped steel is the arch consistent with arc-shaped wave card curvature
The single section such as shaped steel or I-steel, channel steel, shaped steel or rectangular steel tube or the form of multiple section shaped steel combination, arch
Shaped steel is welded in side-lower in arcuate corrugation plate groove, and I-steel, channel steel, shaped steel or rectangular steel tube are respectively positioned on arcuate corrugation
The outer side-lower of plate groove, and be bolted or be welded as a whole with arc-shaped wave card；Filling coagulation in rectangular steel tube
Soil；Arc-shaped wave card is arc corrugated sheet steel.
Advantageous effect：Compared with prior art, the assembled formed steel construction arch bridge unit sheet bar area is big, install convenient,
Construction speed is guaranteed；Using shaped steel structural framing as a whole, overall construction intensity is guaranteed, while avoids arcuate corrugation
The limitation of plate groove size can be applicable under large span and high Conditions of Buried Depth.
