Description
Technical field
The utility model belongs to the structural strengthenings such as science of bridge building, architectural engineering field, in particular to a kind of reinforced steel is mixed
The prestressed fiber cloth reinforced device of the detachable tension ground tackle of solidifying knoll column.
Background technique
The local damage of building and bridge pier column due to structure, the reasons such as aging of material, so that original component can not
The requirement for meeting bearing capacity needs to carry out reinforcement and strengthening to it.When reinforcing, by providing lateral confinement power to pier stud, make coagulation
Soil is in three dimension stress state, to improve the ultimate bearing capacity and ductility of concrete.Currently, common prestressed reinforcement pier stud
Method have prestress steel cuff, steel band, fiber cloth, steel strand wires etc..Relative to traditional reinforcement material, fiber-reinforced composite material
Expect that (Fiber Reinforced Plastics, abbreviation FRP) has tensile strength high, elasticity modulus is high, and it is corrosion-resistant, it is good
It the advantages that designability and work strong operability, is widely applied in steel bar concrete reinforcement.Common FRP material is to concrete
The constraint of component belongs to " passive bound ", and only in the case where concrete sufficiently expands, FRP material just starts to play effect of contraction, deposits
It is not in full use in the high-strength performance of a degree of Stress resort, FRP material.Pre-stress FRP cloth reinforcement technique is one
Kind active reinforcement means, using the high-strength characteristic of FRP, the three dimension stress shape so that the concrete column of hoop constraint has the initiative
State improves bearing capacity, shock resistance, energy dissipation capacity, the ductile performance of performance of concrete column confined.
Currently, the stretching and anchoring device of pre-stressed fiber cloth cloth reinforced concrete pier stud is mostly permanent, tension ground tackle
Not reproducible utilization, higher cost.And anchorage is exposed at pier stud surface, not only influencing its durability also has centainly constructional appearance
It influences.In addition, in common tension ground tackle fibre cloth winding be wound on intermediate plate perhaps on roller bearing when fiber cloth is wider or prestressing force compared with
Greatly, intermediate plate or roller bearing bending deformation are larger when tensioning, so that expection is not achieved in fiber cloth prestress value.
Utility model content
The purpose of this utility model is to provide a kind of prestressed fiber cloth reinforced devices, using the device to fiber cloth
