Description
Technical field
The utility model is related to Strengthening Technique of Reinforced Concrete Structure field, more particularly to prefabricated concrete filled is small-bore
FRP pipe reinforced steel concrete rod structures.
Background technology
At this stage, a large amount of in-service infrastructure due to various reasons, design requirement change, construct by such as material property degradation
Error etc., needs to repair reinforcing.But the maintenance and reinforcement of these infrastructure needs to expend substantial contribution, therefore as each
Significant challenge in state's national economic development.
In European and American developed countries, currently used for build strengthening reconstruction investment accounted for the 1/2 of national construction industry gross investment with
On, according to statistics bureau of the U.S. in estimated data in 2015, the U.S. is used for reinforcement and repair every year, and there are structure or function defects
The fund of bridge is more than 17,000,000,000 dollars.It should be noted that China also faces the problem of same sternness.
Reinforced column is one of main supporting member in concrete structure, and working performance is directly related to structure peace
Complete and use.When existing reinforced concrete column cannot meet requirement for all the foregoing reasons, then need to its into
Row consolidation process, makes it meet requirement.
Existing Reinforced Concrete Reinforcement method includes section augmentativity, fibre reinforced composites (FRP) winding constraint
Method.Section augmentativity increases the section of former xoncrete structure component using with former component same material (such as reinforcing bar and concrete)
Area, to reach a kind of reinforcement means for improving bearing capacity.This reinforcement means is widely used in reinforced concrete structure
The components such as beam, plate, column, have many advantages, such as that principle is simple, use experience is abundant, stress is reliable, low-cost, but there is also wet
Work operations amount is big, curing cycle is long, dramatically increase dead load, occupies the shortcomings of space is more.And FRP winding constraints
Method passes through in the circumferentially wound FRP in concrete column section so that concrete in the case that the lateral expansion for bearing axial compressive force by
Constraint, reaches a kind of reinforcement of concrete post method for improving bearing capacity, which there are unobvious to increase dead load and cut
Face feature, however, this method effect unobvious when reinforcing rectangular or rectangular concrete column.
