Background technique
Size rivers, deep valley danger gully across China currently, CFST Arch Bridge is such as emerged rapidly in large numbersBamboo shoots after a spring rain, concrete-filled steel tube arch
Bridge construction is positive to be a dark horse, from nineteen ninety First CFST Arch Bridge -- and it is short since Sichuan Wangcang Donghe Bridge is built up
More than 400 seat of size steel concrete arch bridge is built up between 26 years, technology is in world lead level, but still there are many be not fully solved or go back
The problem of not handled well.The present invention connect with arch rib for CFST Arch Bridge spandrel column at this stage and sets
Meter is constructed and is generated.
Currently, CFST Arch Bridge spandrel column is free steel pipe column (more) or steel core concrete column (less), steel pipe
The common practice that concrete arch-type bridge spandrel column is connect with arch rib: first by cable hoisting steel tube arch rib, then in arch rib mesh
Mark direct welded still pipe on control point.This way is easy to cause arch rib steel penstock stress to concentrate, and influences the bearing capacity of arch rib；Especially
For the concrete filled steel tube column of concrete perfusion, concrete forms wedge block in the junction of arch rib and column, due to mixed
The vertical pressure of solidifying soil transmitting generates huge extruding force to the connection of arch rib and column, has seriously affected the stress of weld seam
Energy.More scientific, more practical, more economical novel structure and installation method are proposed in this context.
Summary of the invention
The present invention provides a kind of reasonable stress, construction to overcome deficiency existing for the above existing design, construction technology
The joint structure of convenient novel steel tube concrete arch-type bridge column and arch rib.
The technical solution adopted by the present invention is that:
A kind of CFST Arch Bridge column and arch rib nodes construct, for connecting the column and arch rib of concrete arch-type bridge,
The joint structure includes the plane steel plate connecting for the column with concrete arch-type bridge, the curved surface steel for connecting with arch rib
Plate, if the plane steel plate is connect with plate with curved surface by dry joint ribbed stiffener.
Wherein, the inner wall curvature of the plate with curved surface and the outer wall curvature of arch rib are consistent.
Further, the surface of the plate with curved surface is provided with slot weld, and the slot weld is perpendicular to arch rib axial direction
Setting.
Further, several connector pilot pins abutted with the inner wall of column are provided on the plane steel plate.
Preferably, the connector pilot pin is a five side column bodies with chamfering, there is a side of chamfering and stand
The inner wall of column abuts.
Further, several suspension column ribbed stiffeners are provided on the outer wall of the column.
Wherein, the connector ribbed stiffener is the domes that top has a plane, and top planes and plane steel plate weld
Fixation is connect, the inner wall curvature of domes and the outer wall curvature of plate with curved surface are consistent.
Preferably, the plane steel plate, plate with curved surface and connector ribbed stiffener formed by integrally casting form.
It is that the present invention reaches the utility model has the advantages that
1) compared to existing technology, the present invention can be avoided concrete and form wedge block in the junction of arch rib and column
Huge extruding force is generated to its weld seam, structure is enable to be in good stress；
2) joint structure of the invention can formed by integrally casting molding, steel plant's pouring molding greatly reduces than welding fabrication
The harm of residual stress, and can be mass, strong operability, location accuracy are high；
3) novel arch rib of the invention and column connecting node structural texture are simple, light-weight, convenient transportation, practicability
By force.
