Specific embodiment
The embodiment of the present invention is illustrated below in conjunction with the accompanying drawings, embodiment is not construed as limiting the invention：
A kind of steel pipe arch bridge arch rib buckling and hanging mounting structure, which is characterized in that steel pipe arch bridge main arch steel pipe is provided with anchor ear system
System, anchor ear system include two symmetrical semicircle anchor ear units, and semicircle anchor ear unit is arranged on upper strata arch rib, and semicircle wrapper sheet is direct
Main arch steel pipe is wrapped up, semicircle wrapper sheet both sides set connecting plate to be bolted two semicircle anchor ears, and pin is set on connecting plate
Anchor case is connected by keyhole, pin hole with anchor ear by axis pin, and button lashed cable rope is anchored in anchor case.The technical solution at this place is played
Essence technique effect and its realize process be as follows：Structure design of the present invention is simply constructed with the anchor ear method of pier stud bent cap
Principle it is similar, structure stress calculates clearly, rationally, by adjusting the articulated position of anchor case and anchor ear, can hang peace to avoid button
Arch rib is deformed during dress arch rib, constructing operation only carries out that installation exercise is simple and convenient, completion that can be time saving and energy saving
The installation of the interim button point of steel pipe arch bridge, and avoid and the constructing operations such as lifting lug are welded on main arch rib, reduce welding production
Raw residual stress etc. generates the influences such as unbalanced stress to main arch.With it is reasonable in design, be conducive to structure safety and stability, behaviour
Make the advantages that simple and construction cost is relatively low.
The present invention changes interim suspension centre structural arrangement form in the free cantilever erection construction of present CFST Arch Bridge segment,
Security risk when avoiding LFM signal is higher, welding is to the risk of main arch steel pipe damage, solves tearing open after arch rib closure
The problems such as division operation is complicated is a kind of monoblock type button point of steel pipe arch bridge arch rib buckling and hanging installation.
As a further improvement, steel pipe arch bridge main arch steel pipe sets two symmetrical semicircle anchor ear units, semicircle anchor ear
Unit is arranged on upper strata arch rib, and semicircle anchor ear directly wraps up main arch steel pipe for semicircle wrapper sheet, three semicircles are set on semicircle wrapper sheet
Ribbed stiffener, semicircle wrapper sheet both sides set connecting plate to be bolted two semicircle anchor ears, and connecting plate is set with semicircle wrapper sheet
Reinforcing plate carries out reinforcement, sets pin hole on connecting plate, anchor case is connected with anchor ear by axis pin, and button lashed cable rope is anchored in anchor case
It is interior.
Button point construction operation content is as follows：Semicircle anchor ear unit, axis pin and anchor case are made of factory's overall processing, are checked and accepted
Main arch steel pipe is mounted on after qualification, two panels semicircle anchor ear unit is connected by screw bolts, and installation anchor case is connected with anchor ear using axis pin,
Each component installation is complete check it is errorless after start lifting operation and carry out button hang construction；Existing steel pipe arch bridge has been captured to detain temporarily a little
The aspect such as dismounting is complicated, the welding procedure operating time is longer, and safety coefficient is relatively low and security risk is higher the problem of.
With reference to Fig. 3, as a further improvement, comprising contact platform on the main arch steel pipe, contact recessed comprising contacting on platform
Slot, comprising contact projection on semicircle wrapper sheet, contacting groove and contact projection can dock and fix main arch steel pipe.The technology at this place
The technique effect and its realization process for the essence that scheme is played are as follows：It is smooth compared to original main arch steel pipe outside
Structure, this place contact groove and contact projection after improving and can dock and fix main arch steel pipe, therefore fixed more firm, Bu Huifa
It is raw to slide and install unsteady situation.
