Described shaped steel 2 is cross steel, i iron, round steel pipe or square steel pipe.
Leave certain distance between the end face on described aluminium-alloy pipe 1 and bridge pier basis 5, shaped steel 2 is inserted in the bridge pier basis 5 simultaneously.
Leave certain distance between described aluminium-alloy pipe 1 and the bridge pier top bent cap 4.
The concrete steps that realize this structure are:
(1) determines aluminium-alloy pipe diameter and wall thickness according to designing requirement;
(2) determine inner shaped steel cross sectional shape and sectional dimension according to designing requirement, and carry out inner steel installation in position;
(3) carry out pouring concrete by the concrete strength of designing requirement and vibrate, behind some strength, namely form aluminium-alloy pipe binding type steel concrete 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 binding type steel concrete pier pier stud section form can be the various cross sectional shapes such as square, rectangle, 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 inner shaped steel exists, the bridge pier bending resistance, shear resistant capacity all is significantly improved, simultaneously 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, 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 binding type steel concrete 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 binding type steel concrete 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) easy construction: in aluminium-alloy pipe binding type steel concrete pier pier stud, owing to need not to dispose the vertical and horizontal steel bar stress, can save in a large number reinforcement fabrication colligation man-hour, during simultaneously aluminium-alloy pipe binding type steel concrete pier pier stud construction, 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 general, aluminium-alloy pipe constraint reinforced concrete structure is suitable for bridge pier very much, has superperformance advantage and wide application prospect.
