Technical field
The utility model is related to bridge construction device, and steel reinforced concrete combines upright column joint on specifically a kind of tubular arch bridge arch.
Background technology
CFST Arch Bridge is generally ribbed arch bridge, is formed per rib by two panels concrete-filled steel tube truss connecting structure.Bridge floor
Connected between arch rib part above and deck structure using suspension rod, and between the arch rib part and deck structure below bridge floor then
Connected by the upper steel pipe post of arch.
Steel pipe post joint is typically included in the bearing beam that two steel tube of main chord levels of arch rib are fixedly connected on arch, and fixed
It is arranged on seat under the spandrel column on the bearing beam.Using steel-mixed combining structure of strip case more than current bearing beam, or by arch rib it
Arch springing be rolled into reinforced concrete box again thereon plus concrete pad beam structure, both combining structures are complicated, and need to be
Bridge construction site operation, constructs also relatively complicated, connection reliability is poor.
Utility model content
The technical problems to be solved in the utility model is to provide steel reinforced concrete on a kind of tubular arch bridge arch and combines upright column joint, should
Device, provided with steel case ribbed stiffener and to kerve steel, strengthens the bulk strength of steel case, makes pier stud shaped steel and steel in steel case in steel case
Case connection is more firm, and stability is good, and connection reliability is high.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：
Steel reinforced concrete combines upright column joint, including tubular arch on a kind of tubular arch bridge arch, is arranged on the steel case on tubular arch, described
Steel case be connected with tubular arch, the top of tubular arch is at least part of to be arranged in steel case；Pier stud shaped steel inserts steel case
It is interior, steel case ribbed stiffener is set, and steel case ribbed stiffener is vertically arranged with pier stud shaped steel, steel case ribbed stiffener is provided with connection jack in steel case,
Pier stud shaped steel is connected by connecting jack with steel case ribbed stiffener, and pier stud shaped steel is with pier stud shaped steel by being connected to kerve steel；
Cast pier base concrete in steel case.
Using the utility model of above-mentioned technical proposal, compared with prior art, its advantage is：
By setting steel case ribbed stiffener in steel case, the same of the intensity after steel case is cast in itself is improved using steel case ribbed stiffener
When, fixation also is attached to pier stud shaped steel using steel case ribbed stiffener；Kerve steel is entered to advance to pier stud shaped steel in addition, also utilizing
One step is connected, and the utility model annexation is simple, and constructing operation is time saving, laborsaving, cost-effective to improve simultaneously
The reliability of the fastness of connection, stability and connection.
Further, preferred scheme of the present utility model is：
The size of described steel case ribbed stiffener is corresponding to the cavity of steel case, and steel case ribbed stiffener is provided with steam vent.Above-mentioned setting,
Make steel case and steel case ribbed stiffener more closely sealed, so as to improve the intensity after the casting of steel case.
Periphery of the described steam vent along steel case ribbed stiffener is arranged at intervals.By setting steam vent, it is ensured that concrete is poured into
Density, prevent air be full of form bubble in steel case.
The part that described pier stud shaped steel is inserted into steel case is provided with WELDING STUDS.A diameter of 22mm that WELDING STUDS is preferably used,
The center spacing of WELDING STUDS should be not less than 15cm.By setting WELDING STUDS, can further it improve in pier stud shaped steel and steel case
The stability of concrete connection.
The part being arranged at the top of the inwall and tubular arch of described steel case in steel case is equipped with WELDING STUDS.Above-mentioned setting,
Make the connection of steel case and tubular arch more firm, more stable.

Embodiment
With reference to embodiment, the utility model is further illustrated.
Referring to Fig. 1, a kind of upper steel reinforced concrete combination upright column joint of tubular arch Bridge 1 arch, by tubular arch 1, is arranged on tubular arch 1
Steel case 2 is constituted；Steel case 2 is connected with tubular arch 1, and the top of tubular arch 1 is at least part of to be arranged in steel case 2；Pier stud
In the insertion steel of shaped steel 5 case 2, steel case ribbed stiffener 3 is set, and steel case ribbed stiffener 3 is vertically arranged with pier stud shaped steel 5, and steel case adds in steel case 2
Strength rib 3 is connected provided with connection jack, pier stud shaped steel 5 by connecting jack with steel case ribbed stiffener 3, pier stud shaped steel 5 and pier stud shaped steel 5
