Description
Technical field
The present invention relates to a kind of Extruded anchoring tool of FRP tendons and its anchoring process.
Background technique
Fibre reinforced composites (Fiber Reinforced Plastic, abbreviation FRP) muscle is by carbon fiber, glass fibers
It ties up contour performance continuous fiber and is impregnated in the whole muscle material formed in the good resin of corrosion resistance.FRP tendons have it is high-intensitive,
The excellent performance such as low-gravity, corrosion-resistant, endurance, is widely used in field of civil engineering.But FRP tendons are as each to different
Property material, axial strength is higher, and transverse strength is low, and anchoring is more difficult, therefore anchorage technology is to restrict FRP tendons engineering
The bottleneck problem of application.
Common FRP tendons anchorage is broadly divided into bonded and two kinds of clip type.The advantages of bond type anchorage be to FRP tendons not
It causes to damage, by the way that cementing medium is perfused in anchor cylinder, media cures to be bonded can be prepared by test specimen.But some cementing medium streams
Dynamic property is poor, and perfusion is relatively difficult, easily leads to perfusion leakiness, influences anchoring property, and such anchorage needs longer bonding
Length ensures that FRP tendons do not slide with cementing medium.Strand tapered anchorage is mainly used for anchoring prestress steel strand wires, relies on cone
The extruding force that clevis piece and anchor cup generate clamps muscle material, has many advantages, such as that construction is convenient, anchoring efficiency is high.But for it is horizontal see it is each to
The FRP tendons of the same sex, stress of the FRP tendons in anchoring procedure because of part, which is concentrated, occurs early fracture destruction, cannot give full play to FRP
The high intensity of muscle.In addition, in engineering steel strand wires are also used with extruding anchor construction technology, extrusion element, steel are twisted by extruder
Line is squeezed into extrusion die taper hole, and since extrusion element diameter is greater than taper hole diameter, extrusion element is closely compressed in steel strand wires
On, but extruding anchor technology is also only applied to anchoring steel strand wires.
Currently, civil engineering field is being dedicated to the anchoring system that research and development are suitable for FRP tendons both at home and abroad, how to break through existing
The deficiency of anchorage technology proposes a kind of novel anchorage that can more preferably play FRP tendons advantage, greatly FRP tendons will be pushed in soil
The application in wood engineering field.
Summary of the invention
It is safe and reliable that technical problem to be solved by the invention is to provide one kind, and easy to assembly, internal reasonable stress more can
Extruded anchoring tool suitable for fiber-reinforced composite material rib.
To solve the above-mentioned problems, the technical solution of the present invention is as follows:
A kind of Extruded anchoring tool of FRP tendons, including anchor cylinder 1, casing 2 and fibre reinforced composites FRP tendons 3, it is described
Anchor cylinder 1 is the cylinder that one end is equipped with chamfering, and for anchoring FRP tendons, it is logical that the middle part of cylinder is equipped with the taper extended along its center line
Hole.The chamfer angle is identical as 4 taper hole inclination angle of extrusion die.
Casing 2 compatible with conical through-hole is embedded in the conical through-hole；2 outer surface of casing is wedge
Face, 2 internal diameter of casing are matched with FRP tendons 3, that is, the FRP tendons 3 anchored can extend through casing 2, and 2 sets of casing in FRP tendons 3
It prevents from damaging FRP tendons 3 in extrusion process；The center line coincidence of the conical through-hole, casing 2,3 three of FRP tendons of the cylinder.
3 diameter of FRP tendons is less than 2 internal diameter of casing.
The anchor cylinder 1 is equal with the axial length of casing 2, and the design that both greater than FRP tendons 3 anchor force request anchors length
Degree.
The inclination angle theta of the 1 middle part conical through-hole of anchor cylinder is equal with the wedge-shaped inclination angle of outer surface of casing 2, the size of inclination angle theta
It is related to the intensity of FRP tendons and size.
The casing 2 metal good using ductility, including aluminium alloy, copper alloy, kirsite, austenitic stainless steel,
Terne metal.
The anchoring process of the Extruded anchoring tool of above-mentioned FRP tendons, specific steps include:
Step 1, casing 2 is penetrated in anchor cylinder 1, is bonded the wedge surface of casing 2 and the conical through-hole of anchor cylinder 1.
Step 2, the tail end of FRP tendons 3 is run through into casing 2, FRP tendons 3 stretch out the end face certain length of anchor cylinder 1 and casing 2；Institute
Stating the certain length in step 2 is the extrusion deformation elongation greater than anchor cylinder 1, casing 2.
Step 3, the assembly of anchor cylinder 1, casing 2 and FRP tendons 3 is put into extruder 5, anchor cylinder 1 is made to be equipped with the end of chamfering
Face is bonded with the taper hole of extrusion die 4, anchor cylinder 1, casing 2, FRP tendons 3 center line be overlapped with the center line of the taper hole of extrusion die 4,
Grease is equably smeared in 1 outer surface of anchor cylinder.
Step 4, the assembly of anchor cylinder 1, casing 2 and FRP tendons 3 is evenly headed into extrusion die 4 by operation extruder 5, is assembled
Part is squeezed and deformed in extrusion die 4.
Step 5, to the assembly progress quality inspection completed is squeezed, check whether anchorage bending deformation occurs.
The invention has the benefit that Extruded anchoring tool anchors FRP tendons using extrusion process, anchor in extrusion process
The extrusion deformation degree of tool is controllable, therefore can be uniformly distributed in anchorage zone by being squeezed and deformed the compression generated, stress point
Cloth is more reasonable；Meanwhile it being equipped with chamfering in one end of sleeve, the extrusion deformation degree of the end is small, efficiently avoids due to end
Early fracture caused by portion's stress is concentrated destroys, so as to give full play to the high intensity of FRP tendons.
Casing in Extruded anchoring tool uses the good metal material of ductility, plays transition zone in extrusion process
Effect, avoids extruding force and causes to damage to FRP tendons, squeezes and completes rear sleeve and FRP tendons and closely agree with, improve casing and
The interface shear strength of FRP tendons ensure that effective clamping of the anchorage to FRP tendons.
Extruded anchoring tool has many advantages, such as that safe and reliable, small in size, carrying is fast, easy construction, especially suitable for rock soil anchor
Gu, the engineering fields such as bridge cable and structural strengthening.
With reference to the accompanying drawing the Extruded anchoring tool to a kind of fiber-reinforced composite material rib of the present invention and anchoring process make into
One step explanation.
