Description
Technical field
The present invention relates to a kind of anchor device structure, especially a kind of carbon beaverboard anchorage.
Background technology
Carbon fibre reinforced composite（Carbon Fiber Reinforced Polymer/Plastic, abbreviation CFRP）
With lightweight, high-strength, high-modulus, it is corrosion-resistant outstanding advantages of, on a large scale be applied to space flight and aviation, automobile, civil engineering
The multiple fields such as field, the component being made of the carbon fiber board constituted based on carbon fibre reinforced composite are used extensively at present
It is repaired in the reinforcing of the civil engineering structures such as science of bridge building, building engineering.
Currently, most of anchorage is when anchoring carbon fiber board, it is general to be provided with ditch using by two pieces of inner surfaces
The clamping plate of slot presss from both sides carbon fiber board in the trench, by the way that perforative bolt lock up and down is arranged around carbon fiber board in the both sides of intermediate plate
Tight mechanism makes two pieces of intermediate plates securely clamp carbon fiber board, not using carbon fiber board of the anchorage of this kind of structure at anchorage zone
Certain thickness clamping plate is needed only to have to ensure anchoring strength, therefore overall volume is larger, occupy larger space, and from by
The compression that lotus end to free end is subject to is consistent substantially, can not be distinguished the compression that various pieces on carbon fiber board are subject to
Adjust, therefore carbon fiber board bears larger compression always at load-bearing end, be easy to cause carbon fiber board in the region by
Damage makes carbon fiber board premature deterioration before having not been sufficiently achieved its ultimate tensile strength, therefore currently used for anchoring carbon fiber
The anchoring efficiency of the anchorage of plate is not high.
Invention content
Technical problem to be solved by the invention is to provide a kind of preferable carbon fiber boards of compression effect to carbon fiber board
Anchorage, can be smaller by adjusting the compression that hold-down bolt makes carbon fiber board be subject at load-bearing end, to give full play to carbon fiber
The tensile characteristics of plate are tieed up, anchoring efficiency is higher.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of carbon beaverboard anchorage, including anchor cylinder and
At least two panels carbon fiber board is provided with anchor slot in the anchor cylinder, and the carbon fiber board is arranged in the anchor slot,
Be provided with power transmission backing plate between the carbon fiber board and the anchor cylinder, the power transmission backing plate and the carbon fiber board it
Between, be both provided with protection colloid between the adjacent carbon fiber board and between the carbon fiber board and the anchor cylinder,
The top of the anchor cylinder is disposed with multiple rows of compression screw hole group in an axial direction, and it includes at least one often to arrange the compression screw hole group
A compression screw hole is provided with hold-down bolt in the compression screw hole, is arranged between the hold-down bolt and the anchor cylinder
There is first sealing device, the hold-down bolt, which presses, to be arranged on the power transmission backing plate.
It is provided on the power transmission backing plate and compresses counterbore, the compression spiral shell correspondingly with the compression screw hole
Bolt is embedded in the compression counterbore.
It includes at least two compression screw holes often to arrange the compression screw hole group.The pressing force of power transmission backing plate is more stablized,
It is general only to need two compression screw holes of setting.
The protection colloid is made of epoxide resin material.
The anchor cylinder and the power transmission backing plate are refined by steel.Anchoring efficiency is higher.
On one side be provided with opposite with the carbon fiber board intersects twill on the power transmission backing plate.Increase to carbon fiber
The anchoring effect of plate.
It is provided with the second sealing device between the power transmission backing plate and the anchor cylinder.
Compared with the prior art, the advantages of the present invention are as follows washer is arranged between carbon fiber board and the top of anchor cylinder
Plate, hold-down bolt, which passes through, to be compressed screw hole and acts directly on power transmission backing plate, on the one hand compresses that effect is preferable, and when compression passes through power transmission
Backing plate indirectly-acting will not damage carbon fiber board on carbon fiber board；On the other hand by the top of anchor cylinder in an axial direction
Be disposed with multiple rows of compression screw hole group, it may be convenient to the active force at each position for compressing carbon fiber board respectively into
Row is adjusted, when by adjust the hold-down bolt compression that makes carbon fiber board be subject at load-bearing end it is smaller when, carbon fiber board by
Can be avoided the occurrence of at lotus end leads to the generation of damaged phenomenon because compression is excessive, to give full play to the anti-of carbon fiber board
Draw characteristic, anchoring efficiency higher；Since the mutual spacing of the compression screw hole in the tight screw hole group of every row pressure is unrestricted,
The width of anchorage can be effectively reduced at a distance of relatively closely；It is big since influence of the thickness to carbon fiber board of anchorage is little
The big thickness for reducing anchorage makes the carbon fiber board at load-bearing end be greatly reduced at a distance from the works surface at this,
Keep the bending angle of the carbon fiber board at the load-bearing end of anchorage zone smaller, be not easy bending damage, its tensile property can be given full play to.
