Description
Technical field
The utility model relates to the sleeves for SFCB.
Background technique
Steel-continuous-fiber composite-rib (SFCB) is one kind using regular reinforcement as inner core, and outsourcing is longitudinally continuous fiber reinforcement tree
The NEW TYPE OF COMPOSITE muscle of resin-based composite (FRP).206070879 U of patent document CN (a kind of FRP reinforcing bar composite reinforcing), CN
104085117 A (a kind of preparation method suitable for steel-continuous-fiber composite-rib), a kind of 104910509 A of CN (continuous life
Produce polypropylene tape winding package reinforcing bar formed composite reinforcing method) etc. disclose its preparation process.SFCB be integrated with reinforcing bar and
The advantages of FRP, such as its higher elasticity modulus, good corrosion resistance and still have after inner core reinforcement yielding
The characteristics such as stable secondary rigidity.Patent document CN1936206A (steel-continuous-fiber composite-rib reinforced concrete earthquake-resisting structure) is i.e.
Disclosing enhances concrete column using SFCB, and it is small, Yi Xiufu novel anti-to form residual displacement after having good secondary rigidity, shake
Shake structure.However, due to FRP layers of outsourcing of brittleness and not bent characteristic, so that SFCB loses the easy processing of regular reinforcement
Property, the connection and anchoring of SFCB is always to perplex its problem applied in practical projects.
In terms of the connection of regular reinforcement, the most universal, China's building industry professional standard of screw shell connection application
(JG163-2004) material of connection sleeve, threaded connection intensity, quality testing standard, packed and transported etc. have all been made in specific
Regulation.In terms of the connection of pure FRP tendons, since the Transverse Shear Strength of FRP tendons is very low, common clipping anchorage can generate circumferential direction
Stress is concentrated, and causes muscle material to crush destruction, anchoring efficiency is low.So it is mostly to use binding type anchorage form for FRP tendons,
The mode that resin is usually filled in outer steel pipe is anchored and is connected.However, due to being completely dependent on rubbing between resin and FRP tendons
It wipes power to be anchored, required anchorage length is big, and anchoring efficiency is low, and safety guarantee is not high.
Currently, the research of SFCB product at home has been becoming better and approaching perfection day by day, product maturity is also higher and higher.Therefore, at present
It is badly in need of sleeve and anchor measure that exploitation matches with SFCB characteristic, to accelerate the landing application of SFCB.
Utility model content
Purpose of utility model: the purpose of the utility model is to provide the sets of a kind of spreading that can be used in SFCB and anchoring
Cylinder.
Technical solution: to reach this purpose, the utility model uses following technical scheme:
Sleeve described in the utility model for SFCB, including the outer straight interior wedge sleeve sections for accommodating SFCB, and
For accommodating the straight screw sleeve section of the tapping thread section of SFCB inner core steel bar end；Outer straight interior wedge sleeve sections connect straight thread set
Cylinder section, and the side wall of straight interior wedge sleeve sections is equipped with glue filling opening and plastic hole outside, outer straight interior wedge sleeve sections end, which is equipped with, to be blocked.
Further, there are two the outer straight interior wedge sleeve sections, straight screw sleeve section is located at wedge sleeve sections in straight outside two
It is intermediate.This structure can be used for the spreading of linear type SFCB.
Further, the inner wall of the straight screw sleeve section is equipped with internal screw thread, and internal screw thread is attacked with SFCB inner core steel bar end
Silk thread segment matching, and the length of internal screw thread is twice of the tapping thread segment length of SFCB inner core steel bar end.
Further, the outer straight interior wedge sleeve sections have one.This structure can add crotch in the end SFCB to be formed
Anchored end.
Further, the outer straight interior wedge sleeve sections inner wall coarse, the big 4mm of diameter of the aperture ratio SFCB at most narrow place.
Further, the blocking uses flexible material, and diameter matches with SFCB diameter, which is provided with circle protrusion,
Protrusion can be embedded in the gap between SFCB and outer straight interior wedge sleeve sections.
The utility model has the advantages that the utility model discloses a kind of sleeves for SFCB, and compared with prior art, the utility model
Have the following the utility model has the advantages that
1) different from the connection type of pure FRP tendons, the utility model makes full use of the inner core reinforcing bar of SFCB, forms rib machine
Tool anchoring, can greatly shorten length sleeve, reduce anchorage cost, promote anchoring efficiency.
2) the outer straight interior wedge sleeve sections of sleeve leading portion can effectively prevent surface layer FRP to crush, and outer layer FRP may make to be in build-in
The double rub clamp position of glue and inner core reinforcing bar, prevents FRP from effectively being anchored while removing to surface layer FRP, outer straight interior
Wedge sleeve sections and straight screw sleeve section form dual fail-safe.
3) by appropriate repacking, the utility model can be used for making crotch anchored end in the end SFCB, for improving
The anchoring property of SFCB.
4) the utility model tube-in-tube structure is simple, and reasonable stress, manufacturing cost is low, low to material requirements, can industrialize big
Large-scale production can pave the way for the practical engineering application of novel SFCB.
