Description
Technical field
The utility model relates to anchoring, particularly a kind of new type FRP rib tape screw plug bond type anchorage by lacing wire (rope) material in civil engineering.
Background technology
Under erosion environment, easily there is corrosion in reinforcing bar or the prestress wire of reinforced concrete structure, causes concrete structure to occur endurance issues.Fibre reinforced composites (Fiber Reinforced Polymer, being called for short FRP) muscle has the advantages such as high-strength light, corrosion-resistant, underrelaxation and anti-fatigue performance are good, be used in concrete structure using FRP muscle as vertical muscle or presstressed reinforcing steel, the durability of concrete structure can be improved, there is good economic and social benefit.
FRP muscle is made up of fiber and polymeric matrix two parts, belongs to anisotropic material, and its shear strength is well below tensile strength.In tension test, directly clamping FRP muscle easily causes the sheared destruction of gripping section, cannot obtain its tensile strength; The traditional strand tapered anchorage being used in prestressed reinforced concrete structure is used for the anchoring of prestressed FRP rebar, easily cause FRP muscle to be cut up at ground tackle place, its tensile strength cannot give full play to.Around the anchorage problem of FRP muscle, carry out correlative study both at home and abroad, have developed corresponding ground tackle.Such as, in order to strengthen the adhesion stress of cementing agent and anchor cylinder, adopt inwall with the anchor cylinder of boring section continuously; In order to prevent FRP muscle from being crushed, adopt the soft metal intermediate plate of taper.But the anchor tube length of existing FRP muscle bond type anchorage is spent greatly, and the processed complex of follow-on bonded or strand tapered anchorage, cost is higher.Therefore, develop and a kind ofly process FRP muscle anchor device simple, easy to use, to promoting that the investigation and application of FRP muscle is significant.
Utility model content
The deficiency that the utility model exists for prior art and defect, provide a kind of anchorage length little, process easy, that anchoring property is good FRP rib tape screw plug bond type anchorage.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of new type FRP rib tape screw plug bond type anchorage, comprise anchor cylinder and annular gasket, described anchor cylinder two ends are fixed with annular gasket respectively, also comprise screw plug, screw plug is threaded by pull end with anchor cylinder, and described annular gasket circle centre position is provided with one for being set with the central through hole of FRP muscle, and the center of circle of this annular gasket is positioned on the center line of described anchor cylinder.
In above-mentioned new type FRP rib tape screw plug bond type anchorage, described screw plug is made up of the cylinder barrel segment be connected with anchor drum outer wall, reducer and the cylinder boss section that is sleeved on FRP muscle external surface.
In above-mentioned new type FRP rib tape screw plug bond type anchorage, described anchor barrel structure is the straight cylinder barrel shaped of inwall; Described annular gasket is pasted onto on the end face of anchor cylinder by cementing agent.
The beneficial effects of the utility model are:
The utility model FRP rib tape screw plug bond type anchorage is designed by the screw plug of end, improve the interaction between anchor cylinder and cementing agent, enhance the constraint to cementing agent straight skidding, effectively prevent cementing agent from skidding off, reduce the length of anchor device, compared with being ground tackle with traditional bonding, the anchor cylinder of equal length, improves bearing load (see table 1 sample type and test structure contrast table); And ground tackle parts are without the need to special processing, low to material requirements, structure is simple, reasonable in design, easy to use, and mounting process is simple, with low cost, and screw plug adopts screw thread to be connected with anchor cylinder, improves anchoring efficiency.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail:
Embodiment 1: see Fig. 1 ~ 4, a kind of new type FRP rib tape screw plug bond type anchorage, comprise anchor cylinder 3 and annular gasket, described anchor cylinder two ends are bonded with annular gasket 5,7 respectively, wherein, anchor cylinder 3 one end is free end, one end is for being subject to pull end, free end pastes annular gasket 5, tension section is pasted annular gasket 7, also comprised screw plug 6, screw plug 6 is threaded by pull end with anchor cylinder 3, the circle centre position of described annular gasket 5 and annular gasket 7 is respectively equipped with one for being set with the central through hole of FRP muscle, and the center of circle of this annular gasket is positioned on the center line of described anchor cylinder 3.Described screw plug 6 is made up of the cylinder barrel segment be connected with anchor cylinder 3 outer wall, reducer and the cylinder boss section that is sleeved on FRP muscle external surface, and described screw plug 6 adopts reducer union.Described anchor cylinder 3 structure is the straight cylinder barrel shaped of inwall, adopts seamless steel pipe to make.Described annular gasket 5 and annular gasket 7 are pasted onto on the end face of anchor cylinder 3 respectively.
The mounting method that the utility model is arranged on FRP muscle material is: comprise the following steps:
Step one: anchor cylinder 3 inside is carried out cleaning, eliminating rust, and at anchor cylinder 3 by pull end threading 2;
Step 2: will the free end end face of anchor cylinder 3 be fixed upper annular gasket 5 and seal;
Step 3: by the suit screw plug 6 of FRP muscle 1 one end;
Step 4: pour into cementing agent by pull end in anchor cylinder 3 from anchor cylinder 3, until anchor cylinder 3 inside is full of cementing agent, complete filling adhesive, again FRP muscle 1 is sleeved on the one end in screw plug 6 to be inserted in anchor cylinder 3 by the central through hole of tension end annular gasket 7, makes its end enter in the annular gasket central through hole 8 of anchor cylinder 3 free end;
Step 5: annular gasket 8 is fixed on anchor cylinder 3 by pull end end face, then screw plug 6 is connected with the external screw thread 2 on anchor cylinder 3 by internal thread;
Step 6: to be bonded dose solidify after, remove the sealing of anchor cylinder 3 free end;
Step 7: according to step one to six ground tackles installing the FRP muscle other ends.
The utility model FRP rib tape screw plug bond type anchorage is designed by the screw plug of end, improves the interaction between anchor cylinder and cementing agent, enhances the constraint to cementing agent straight skidding, effectively prevent cementing agent from skidding off, bearing load.
Above detailed description of the invention is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement, all should be included within protection domain of the present utility model.
