Abstract
The utility model relates to an aluminum alloy pipe restriction reinforced concrete bridge pier post, which comprises a bridge pier base, a bridge pier post upper part cover beam and an aluminum alloy pipe, wherein the aluminum alloy pipe is positioned between the bridge pier base and the bridge pier post upper part cover beam, a plurality of vertical steel bars with the same direction as the pipe length direction and a plurality of transverse steel bars parallel to the pipe surface are arranged in the aluminum alloy pipe, and concrete is cast among the vertical steel bars, the transverse steel bars and the inner wall of the aluminum alloy pipe. The external aluminum alloy pipe does not directly take part in the vertical stress of the bridge pier post and only restricts the internal reinforced concrete in the transverse direction, so the deformation capability and the anti-shock capability of the reinforced concrete bridge pier post are improved. Because of good anti-corrosion performance and good appearance effect of the aluminum alloy pipe, the durability and the appearance effect of the pier post can also be obviously improved. During the construction, the aluminum alloy pipe can also be used as a template for reaching the effects of template saving and construction convenience, and the aluminum alloy pipe restriction reinforced concrete bridge pier post can be applicable to the bridge pier post components of bridges including railway bridges, highway bridges, municipal engineering bridges and the like and has good application prospects.

(2) arrange reinforcing bar according to the longitudinal reinforcement of designing requirement and lateral tie form of reinforcement and quantity;
(3) carry out pouring concrete by the concrete strength of designing requirement and vibrate, behind some strength, namely form aluminium-alloy pipe confined concrete bridge pier until the maintenance of aluminium-alloy pipe inner concrete;
(4) aluminium-alloy pipe and bridge pier basis end face is reserved certain distance;
(5) aluminium-alloy pipe and bridge pier top bent cap are reserved certain distance;
(6) aluminium-alloy pipe constraint reinforced concrete bridge pier pier stud section form can be the various cross sectional shapes such as square, circle and round end type.
Compare with traditional reinforced concrete bridge pier, the utility model patent has the following advantages:
(1) anti-seismic performance is good: because the bridge pier inner concrete is subject to the horizontal restrain of external aluminium compo pipe, the concrete deformation ability is significantly improved, especially for the concrete of higher-strength grade, owing to be subject to good constraint, the high-strength concrete deformability is greatly improved, and pier stud ultimate deformation ability, ductility and energy dissipation capacity all can significantly improve, therefore, have good anti-seismic performance, can effectively prevent and avoid bridge pier under large shake, heavy damage to occur and collapse.
(2) excellent in durability: in aluminium-alloy pipe constraint reinforced concrete bridge pier pier stud, owing to place the aluminium-alloy pipe of pier stud outside to have good decay resistance, the endurance quality of bridge pier obtains fine raising, can effectively solve the crucial difficult problem of bridge pier durability Design;
(3) appearance effect is good: because aluminium-alloy pipe itself has preferably appearance effect, aluminium-alloy pipe constraint reinforced concrete bridge pier pier stud need not to carry out outer list processing, can have good appearance effect, application has remarkable performance advantage for bridge especially Municipal bridge;
(4) save template: during the construction of aluminium-alloy pipe constraint reinforced concrete bridge pier pier stud, aluminium-alloy pipe can play the construction formwork effect, can save template material and recruitment, easy construction;
(5) recovery rate is high: aluminum alloy materials has very high recovery rate, can realize nearly 90% recovery under low cost recovery, and composite energy-saving environment protection demand and sustainable development need.
In addition, aluminium-alloy pipe constraint reinforced concrete bridge pier has also that processing and fabricating is convenient, weight is light and the advantage such as convenient transportation.In general, aluminium-alloy pipe constraint reinforced concrete structure is suitable for bridge pier very much, has superperformance advantage and wide application prospect.
