Abstract
Provided is a square bridge pier with built-in FRP ribs. Reinforced concrete serves as a main body of the square bridge pier, a steel binding strip is arranged in the circumference direction of the top end of the bridge pier, and the FRP ribs adhere to the inside of a concrete protecting layer inside the bridge pier. According to the square bridge pier, slits are effectively avoided while structural strength can be improved, and bridge pier performance reduction under the conditions that steel bars are corroded is reduced.
Description
Technical field
The present invention relates to bridge technology field, particularly a kind of square bridge pier of built-in FRP muscle.
Background technology
FRP--(Fiber Reinforced Plastics) fibre-reinforced plastics, by fortifying fibre and matrix composition.The diameter of fiber (or whisker) is very little, and generally, below 10 μ m, defect is less again less, and breaking strain is about in 30/1000ths, is fragile material, easy damaged, ruptures and is corroded.Matrix phase is for fiber, and intensity, modulus are all much lower, but can withstand large strain, often has viscoplasticity and elastoplasticity, is toughness material, has been applied in field of civil engineering.
The square bridge pier of existing built-in FRP muscle is all take steel concrete as main body, often because of climatic factor, construction wrong, design and construction mistake, change to use function or use and unreasonable etc. cause crack, repair difficulty larger.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of square bridge pier of built-in FRP muscle, there is feature easy to use simple in structure.
To achieve these goals, the technical solution used in the present invention is:
A square bridge pier for built-in FRP muscle take steel concrete as main body, arranges steel band 3 in bridge pier 2 top circumferential direction, in bridge pier 2 inner concrete toppings, is bonded with FRP muscle 1.
The present invention compared with prior art, can, improving in structural strength, effectively prevent that crack from occurring, has avoided the situation of bridge pier hydraulic performance decline in situation that reinforcing bar is corroded.
Accompanying drawing explanation
Accompanying drawing is top view of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is carried out to more detailed explanation.
As shown in the figure, the present invention is a kind of square bridge pier of built-in FRP muscle, take steel concrete as main body, in bridge pier 2 top circumferential direction, steel band 3 is set, and in bridge pier 2 inner concrete toppings, is bonded with FRP muscle 1.
The use of FRP muscle 1 can strengthen concrete structure performance, this structure has chemical bond power, make cement colloid and muscle surface produce suction-operated, and when after concrete shrinkage, FRP muscle 1 can be wrapped to generation frictional force, the extruding force between concrete and FRP muscle 1 is larger, and contact surface is more coarse, frictional force is just larger, and the steel band 3 outside bridge pier 2 can continue to guarantee maintaining of this power.Therefore the present invention has increased structural strength to a great extent, has improved corrosion resistant degree simultaneously.
Claims (1)
1. a square bridge pier for built-in FRP muscle, take steel concrete as main body, is characterized in that, in the circumferential direction of bridge pier (2) top, steel band (3) is set, longitudinal bonding FRP muscle (1) in bridge pier (2) inner concrete topping.
