Description
Technical field
The utility model is related to anchorages, are specially a kind of pre-stressed carbon fiber plate detachable anchorage device.
Background technology
Pre-stressed carbon fiber plate is widely used in the reinforcing and upgrading of building concrete.Anchorage is prestressing force carbon
Load suffered by carbon fiber board can be efficiently transferred to be reinforced in building by the core of plate.Existing anchorage mainly divides
For two major classes, i.e.,：Permanent anchorage and detachable anchorage device.For permanent anchor after building is reinforced, anchorage will permanently and carbon fiber
Plate is connected, although with stronger stability, for this anchorage due to processing and material problem, cost is higher, it is difficult to universal
It promotes and applies.After detachable anchorage device is reinforced, anchorage can be dismantled and recycled, and overall cost cost substantially reduces, simultaneously
Compared to permanent anchorage, there is no reduce on safety and stability.Existing detachable anchorage device such as Simpson's anchorage, can
Relatively low occasion is required for pre-stress design value in some strenthening members, but higher environment is required for some design loads,
It is difficult to be used widely.
The content of the invention
The technical issues of the utility model solves is to provide a kind of pre-stressed carbon fiber plate detachable anchorage device, to solve
The shortcomings that in above-mentioned background technology.
The technical issues of the utility model solves is realized using following technical scheme：A kind of pre-stressed carbon fiber plate can
Anchorage is dismantled, is formed including detachable anchorage device, slideway, tensioning support, anchor slab and carbon fiber board, it is characterized in that：The slideway peace
Mounted in bottommost, the detachable anchorage device is mounted on the top of the slideway；Another part is followed successively by the tensioning from top to bottom
Bearing, the anchor slab, the carbon fiber board；The detachable anchorage device is divided into top, gland, voussoir, pedestal, five parts of cancellation,
One end of the top is connected with the side of the gland, and the other end is connected to the side of the tensioning support；The voussoir peace
Mounted in described pedestal the upper surface of.
In the utility model, the detachable anchorage device is wedge-shaped design, and the voussoir has identical inclination angle with wedge groove,
Angle is in 2 with horizontal line0-50。
In the utility model, the voussoir is 40Cr materials, other are stainless steel, 3Cr13 materials or 2Cr13 materials
Matter.
It is be bonded with epoxy adhesive between concrete surface in the carbon fiber board in the utility model, the epoxy glue
The soft metal material that glutinous agent is thickness 1mm-3mm.
The beneficial effects of the utility model：The utility model provides a kind of detachable anchor of wedge shape based on frictional resistance effect
Tool, the inclination angle of wedge-shaped anchorage is 2o-5o, which has lower cost advantage compared to solid anchor, and universality is stronger.It is viscous
Connect carbon fiber board is the soft metal plate that thickness is 1mm-3mm, which can be aluminium sheet, copper coin and aluminium alloy
Plate so can eliminate stress during prestressing force is applied, and preventing " notch effect " or other causes carbon fiber board to be sent out
Raw improper destruction.The pre-stress design value of detachable anchorage device is relatively broad, in the range of reachable 800MPa-1500MPa, stability
It is higher with security simultaneously because detachable anchorage device can be recycled, be greatly reduced in cost.

Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness for realizing the utility model are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Embodiment：As shown in Figure 1, Figure 2, Figure 3 shows, 1. a kind of pre-stressed carbon fiber plate detachable anchorage device, including detachable anchor
Tool 1, slideway 2, tensioning support 3, anchor slab 4 and carbon fiber board 5 form, it is characterized in that：The slideway 2 is mounted on bottommost, described
Detachable anchorage device 1 is mounted on the top of the slideway 2；Another part is followed successively by the tensioning support 3, the anchor slab from top to bottom
4th, the carbon fiber board 5；The detachable anchorage device 1 divides to come directly towards 6, gland 7, voussoir 8, pedestal 9,10 5 parts of cancellation, described
One end of top 6 is connected with the side of the gland 7, and the other end is connected to the side of the tensioning support 3；The voussoir 8 is pacified
Mounted in described pedestal 9 the upper surface of.The detachable anchorage device 1 is wedge-shaped design, and the voussoir 8 inclines with wedge groove with identical
Angle, angle 20-50.The voussoir 8 is 40Cr materials, other are stainless steel, 3Cr13 materials or 2Cr13 materials.
The carbon fiber board 5 is be bonded with epoxy adhesive between concrete surface, and the epoxy adhesive is the soft gold of thickness 1mm-3mm
Belong to material.
Operation principle：As shown in Figure 1, Figure 2, Figure 3 shows, detachable anchorage device pre-stressed carbon fiber plate system is made of five parts：
Detachable anchorage device 1, slideway 2, tensioning support 3, anchor slab 4 and carbon fiber board 5 form.Detachable anchorage device by top 6, gland 7, up and down
Voussoir 8, pedestal 9 and 10 this five part of cancellation composition.During actual tensioning carbon fiber board 5, hydraulic pressure is placed in tensioning support 3
Jack, the gland 7 of the hydraulic jacking ram contact detachable anchorage device 1 after pressurization, after gland 7 is subject to active force, is transferred to
In voussoir 8, and then intermediate carbon fiber board 5 is squeezed, and carbon fiber board 5 is bonding with there is epoxy adhesive between concrete surface, it is complete
Into whole process from jack to the transmittance process of coagulation soil stress.It is strained simultaneously because carbon fiber board 5 generates, and anchorage
In top 6 can adjust spacing between anchorage and tensioning support 3, so jack is withdrawn after tensioning, when about 12-24 is small
Afterwards, the epoxy adhesive between carbon fiber board 5 and concrete is fully cured, and anchorage and tensioning support 3 are i.e. detachable, only by anchor slab
4 fix.
Carbon fiber board 5 is used as intermediate medium, carries entire stress transfer.And to carbon fiber board 5, effectively anchoring is
Play the premise of its high tensile.Anchorage uses wedge-shaped design in the utility model, and wedge groove and wedge block have in anchorage
Identical inclination angle, angle are 2-5 °, and in anchorage in addition to voussoir is using 40 Cr materials, other are stainless steel, 3Cr13 or 2Cr13
Material.In addition, at carbon fiber board both ends, length is consistent with anchorage length to be located to paste and carbon fiber width using chemical adhesive
Unanimously, the soft metal plate of thickness about 1mm-3 mm, so can during applying prestressing force eliminate stress concentration the problem of,
Preventing " notch effect " or other causes carbon fiber board that improper destruction occurs.Simpson's anchorage uses mechanical anchor formula,
Be directly connected between anchorage and carbon fiber board, and carbon fiber board be brittleness material, if in stretching process stress cross conference cause it is non-
It is normal to destroy, so the application of Simpson's anchorage is more limited to.The patent of this patent design invention is exactly to solve the problems, such as this, is applied
The prestressing force scope added has widened its use scope significantly up to 800MPa-1500MPa.
The basic principle of the utility model and main feature and the advantages of the utility model, one's own profession has been shown and described above
