Description
Technical field
This utility model belongs to engineering field, particularly to a kind of device fixedly securing composite material bar.
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.
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
Fixedly secure the device of composite material bar.
Technical scheme：A kind of device fixedly securing composite material bar that this utility model provides, including left anchorage, right anchor
Tool, connecting tube, composite material bar, metal tube；It is respectively equipped with composite material bar groove in the middle part of described left anchorage, right anchorage, described multiple
It is provided with ring shaped thread tooth in condensation material muscle groove；Described composite material bar is provided with and composite wood with the contact surface of composite material bar groove
The tooth of the ring shaped thread tooth cooperation in material muscle groove；Described composite material bar sequentially passes through left anchorage, connecting tube, right anchorage；Described
Composite material bar one end is provided with cylinder hole, and metal tube is fixed in cylinder hole.
As improvement, described left anchorage, right anchorage are respectively cuboid or cylinder.
Improve as another kind of, described left anchorage, the diameter of the composite material bar groove of right anchorage are less than or equal to composite wood
The external diameter of material muscle.
Improve as another kind of, described left anchorage, right anchorage be respectively the upper grip block being connected by fixing bolt and under
The fixture of grip block composition.
Improve as another kind of, described left anchorage, right anchorage are connected by connecting bolt with connecting tube.
Improve as another kind of, described connection inside pipe wall is provided with skid resistant course.
As improving further, described skid resistant course is metallic particles coating.
Improve as another kind of, the external diameter of described metal tube is more than or equal to the internal diameter of cylinder hole.
Beneficial effect：The apparatus structure of what this utility model provided fixedly secure composite material bar is simple, easy to use, becomes
This cheap, high capacity, joint efficiency is high；This utility model passes through projection and the groove fixing composite material that setting matches
Muscle, 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；Additionally, increase skid resistant course can be further
Increasing friction force, makes fixation more firm.Additionally, connecting tube can be random length, thus greatly enhancing bonding strength.
