Description
Technical field
The invention belongs to science of bridge building fields, and in particular to a kind of reinforcing device and method of suspention system arch bridge.
Background technique
Arch bridge, it is extensive with material because it is had a graceful figure, it is a kind of common bridge type.Suspention system arch bridge bears bridge using crossbeam
Deck load, longitudinal strength is insufficient, and driving seismaesthesia is obvious, and comfort level is poor.In addition, suspention system arch bridge safety is poor, if horizontal
Beam destroys, and will affect full-bridge normal use.Currently used reinforcement means is that steel stringer is added between crossbeam, and and concrete
Floorings are connected.There are the following problems for reinforcing mode in this way: the temperature difference is big between reinforcing steel stringer and concrete slab, can generate
Biggish internal force, access bridge concrete slab cracking.
Summary of the invention
To solve the above problems, of the invention provides a kind of reinforcing device and method of suspention system arch bridge.
The invention provides the following technical scheme:
A kind of bracing means of suspention system arch bridge is steel case concrete stringer 1；The steel case concrete stringer 1 by
Steel case 3 and concrete 5 form, and steel case 3 is double-layer structure, and concrete 5 is filled in the double-layer structure of steel case 3, make steel case coagulation
The inside of native stringer 1 forms hollow structure；Concrete 5 is connect with steel case 3 by pin 4.
A kind of reinforcement means of suspention system arch bridge bears external load effect by increasing steel case concrete stringer 1；Specifically
Steps are as follows for reinforcing:
(1) steel case 3 is set up between adjacent crossbeam, then the casting concrete 5 in steel case 3, the two is connected by pin 4
It connects, forms steel case concrete stringer 1；
(2) after the completion of steel case concrete stringer 1 is constructed, all sunpenders 2 are replaced, the lower end of new sunpender 2 is fixed on steel case
The inside of concrete stringer 1；
(3) floorings are installed；
(4) installation drainage system and central anticollision barrier；
(5) it pours full-bridge to mat formation, railing is installed.
Effect of the invention and have an advantage that: steel case can be used as template, facilitate construction；Concrete improves the rigid of steel case
Degree, the two play a role jointly.Steel case and Combined concrete form the rigidity that steel case concrete stringer improves structure, improve bridge
Comfort.Casting concrete in steel case adds the temperature difference between steel case and floorings, reduces in the temperature of structure after reducing
Power.The device of the invention and method overcome various problems existing in the prior art.

3. removing main bridge floorings.
4. precasting yard prefabricated bridge.
5. the construction steel case concrete stringer 1 at the steel stringer of dismounting, steel case concrete stringer 1 is used as bracing means, holds
It is acted on by external load；Steel case concrete stringer 1 is made of steel case 3 and concrete 5, and the concrete 5 is filled in the double of steel case 3
In layer structure, the two is connected by pin 4；The inside of steel case concrete stringer 1 is hollow structure, specifically as shown in Fig. 3,4,5.
6. replacing all sunpenders 2 after the completion of steel case concrete stringer 1 is constructed, replacement is a pair of every time.
7. the new prefabricated floorings of installation, cast-in-place 3 two sides floorings of steel case.
8. removing and pouring concrete at deck expansion joint again, new expansion joint is installed.
9. construct cast-in-place floorings and anticollision barrier.
10. installing drainage system and central anticollision barrier.
11. pouring full-bridge again to mat formation, railing is installed.
Steel case concrete stringer 1 high 2.2m, wide 1m；Steel case 3 top wall thickness 20mm, web wall thickness 12mm, pin 4 are long
150mm。
Material property: steel case 3 uses Q235 steel, and concrete 5 uses C30 concrete.
Class of loading: I grades of highway.
Desin speed: 60km/h.
