Abstract
The invention discloses a carbon fiber plate anchorage device limiting tensioning block which comprises a block body. A square through hole for a carbon fiber plate to penetrate through is formed in the block body, a curved surface concaved inwards is formed in the face, making contact with an anchorage device, of the block body, and a limiting groove communicated with the square through hole is formed in the center of the curved surface. According to the carbon fiber plate anchorage device limiting tensioning block of the structure, in the process that a carbon fiber plate is stretched, shear stress in the thickness direction of the carbon fiber plate can be avoided, stress concentration of the tensioning block can be reduced, and therefore the service life of the tensioning block is prolonged.
Description
Technical field
The present invention relates to the spacing stretch-draw block of a kind of carbon beaverboard anchorage.
Background technology
In recent years, the high strength complex fiber material such as carbon fiber board is widely used in the field of reinforcement of civil construction project.The surface normally carbon fiber board being pasted onto mixed earth component is used for the intensity improving mixed earth component.If the surface being reinforced component will be anchored in after carbon fiber board stretch-draw, the flexural strength being reinforced component can be improved, anti-strong, the service efficiency of carbon fibre material can also be improved, reduce reinforcement cost.
Increase component strength with carbon fiber board, need first by tensioning system, carbon fiber board to be stretched, then utilize ground tackle to be anchored at carbon fiber two ends and be reinforced on component.Stretch-draw block belongs to the important component of tensioning system, and in the process stretched to carbon fiber board, first carbon fiber board is fixed by ground tackle, and post tensioning block drives ground tackle to move, and realizes the stretching to carbon fiber board.Existing stretch-draw block, owing to there is no position limiting structure in a thickness direction, therefore move in the process of stretching carbon fiber board at drive ground tackle, easily occur that the central plane of ground tackle does not overlap with the central plane of stretch-draw block, ground tackle through-thickness offsets downward or upward, this just makes carbon fiber board there is shear stress in a thickness direction, thus cause carbon fiber board to occur shear failure, in addition, in drawing process, also easily cause the stress of stretch-draw block itself to be concentrated, thus substantially reduce the application life of stretch-draw block.
Summary of the invention
In view of this, the object of this invention is to provide the spacing stretch-draw block of a kind of carbon beaverboard anchorage, in the process that carbon fiber board is stretched, carbon fiber board can not only be avoided to there is shear stress in a thickness direction, and the stress that can reduce stretch-draw block itself is concentrated, thus improve the application life of stretch-draw block.
The present invention is solved the problem by following technological means: the spacing stretch-draw block of a kind of carbon beaverboard anchorage, comprise block, described block is provided with the square through hole passed for carbon fiber board, the one side that described block contacts with ground tackle is provided with the curved surface caved inward, and described center of surface is provided with the stopper slot be communicated with square through hole.
Further, four drift angles of described stopper slot are provided with arc notch.
Further, the shape of described arc notch is semicircle.
Further, the size of described square through hole is less than the cross section of carbon fiber board.
Beneficial effect of the present invention: the spacing stretch-draw block of carbon beaverboard anchorage of the present invention, comprise block, described block is provided with the square through hole passed for carbon fiber board, the one side that described block contacts with ground tackle is provided with the curved surface caved inward, and described center of surface is provided with the stopper slot be communicated with square through hole.The spacing stretch-draw block of carbon beaverboard anchorage of this structure, in the process that carbon fiber board is stretched, carbon fiber board can not only be avoided to there is shear stress in a thickness direction, and the stress that can reduce stretch-draw block itself is concentrated, thus improve the application life of stretch-draw block.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is that master sees schematic diagram.
Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail, as shown in Figure 1-2: the spacing stretch-draw block of carbon beaverboard anchorage of the present embodiment, comprise block 1, described block is provided with the square through hole 2 passed for carbon fiber board, the size of described square through hole is less than the cross section of carbon fiber board, the one side that described block contacts with ground tackle is provided with the curved surface 3 caved inward, and described center of surface is provided with the stopper slot 4 be communicated with square through hole.The spacing stretch-draw block of carbon beaverboard anchorage of this structure, on the one hand, arranges curved surface in the one side contacted with ground tackle, in the process of stretching carbon fiber board, can make stretch-draw block uniform force, the stress that can effectively reduce stretch-draw block is concentrated, and substantially increases the application life of stretch-draw block; On the other hand, in center of surface, stopper slot is set, ground tackle embeds in stopper slot, stopper slot can guarantee steadiness and the accuracy of anchorage installation, not only make ground tackle can not come to nothing in the process of stretching carbon fiber board to drop, and the central plane of ground tackle is overlapped all the time with the central plane of stretch-draw block, ground tackle can not slide by through-thickness downward or upward, effectively prevent carbon fiber board and produce shear stress in a thickness direction, prevent carbon fiber board shear failure.
As the further improvement of technique scheme, four drift angles of described stopper slot are provided with arc notch 5, and the shape of described arc notch is semicircle.In drawing process, ground tackle and spacing cell wall extrude mutually, elastic deformation to a certain degree can be there is in the with angle face of being squeezed, the impact distortion that drift angle is subject to two other aclinal face is minimum and stressed maximum, therefore easily there is stress and concentrate in drift angle place, and this has had a strong impact on the application life of stretch-draw block, and arranging of arc notch can avoid drift angle place stress to concentrate, make distribution of force more reasonable, effectively improve the application life of stretch-draw block further.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
