Description
Technical field
This utility model belongs to engineering field, particularly to a kind of composite material bar suspension cable anchorage device, further relates to one kind
Pretightning force tooth connecting-type anchorage for composite rope.
Background technology
With the muscle that composite makes, there is high-strength light, endurance and anticorrosive, in civil engineering
Show advantage and be increasingly widely applied.But because composite material bar compares reinforcing bar, its horizontal comprcssive strength and
Shear resistance is relatively low, thus it anchoring be different from regular reinforcement anchorage style.From force-mechanism, composite material bar
Anchorage can be divided into mechanical type and bonded two kinds：Mechanical type anchorage clamps muscle material mainly by intermediate plate, by the frictional force on muscle material surface
Power transmission, easily produces stress concentration in clamping process, causes the fracture of muscle material few fibers silk thus being cut up in advance；Bonded
Anchorage is mainly by the cohesive force power transmission at muscle material interface and colloid, but its anchorage length is longer, and section shearing stress distribution is uneven
Problem affect its anchoring efficiency.
Faced by rope is main when applying is connectivity problem.Common metal rope becomes eye to realize anchoring even by snap-type
Connect.But for composite rope, because the high rigidity of itself is it is easy to fractureing and damaging, so being not suitable for picture
The connected modes such as knotting, braiding eye, otherwise can cause the serious damage of fiber.
Utility model content
Utility model purpose：In order to overcome the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide one kind
Composite material bar suspension cable anchorage device；Another object of the present utility model is to provide a kind of pretightning force for composite rope
Tooth connecting-type anchorage.
Technical scheme：A kind of composite material bar suspension cable anchorage device that this utility model provides, is provided with ring-type including end
The composite material bar of thread, metal fixture, fixing bolt；It is provided with composite material bar groove in the middle part of described metal fixture, described multiple
It is provided with the tooth with the cooperation of composite material bar end ring-type thread in condensation material muscle groove；Described composite material bar is provided with a pair and hangs down
Directly arrange and not in the through hole of same longitudinal section, described metal fixture is provided with the bolt hole with through hole cooperation；Described fixing spiral shell
Bolt passes through bolt hole and through hole.
As improvement, described metal fixture is cuboid or cylinder.
Improve as another kind of, the ring set that described metal fixture is formed in one.
As improving further, the diameter of the composite material bar groove of described metal fixture is less than composite material bar external diameter.
Improve as another kind of, described metal fixture is the upper grip block being connected by grip bolt and lower grip block composition
Fixture.
Improve as another kind of, described composite material bar groove includes lobe and depressed part；Described lobe surface is provided with
Skid resistant course；Described depressed part surface is provided with wearing layer.
Improve as another kind of, described skid resistant course is metal skid-proof coating.
Beneficial effect：The composite material bar suspension cable anchorage apparatus structure that this utility model provides is simple, easy to use, cost
Cheap, high capacity, joint efficiency is high；After metalwork and composite material bar are assembled by this utility model by tooth, by certain
Method applies radial pressure on composite tooth, then by composite root position shearing strength at intersection ability and contact surface
Frictional resistance jointly transmit external load, thus reaching the purpose of anchoring composite materials muscle.
The method that this utility model mainly provides two kinds of applying pretightning forces：
One is to apply pretightning force by high-strength bolt.Process the tooth of multiple tracks ring first on composite material bar, in metal
Process, on fixture, the tooth matching with composite material bar tooth, and processing bolt hole on metal fixture；Then by the occlusion of tooth
Assembling, and assemble high-strength bolt；Finally moment of torsion is applied to high-strength bolt, thus composite material bar is applied with a certain size radial direction
Pretightning force.
Two is to apply pretightning force by interference fit.Will external diameter be slightly smaller than composite material bar diameter metal fixture heating
Be inserted in composite material bar after expansion, after cooling, metal fixture to contract extruding composite material muscle, then outer steel sleeve with compound
Larger radial compressive stress is produced on material rib interface.
Three is by increasing metal skid-proof coating, considerably increasing frictional force, make fixation more firm.
