Technical Field
The utility model relates to a prestressed carbon fiber plate flat anchorage device with clamping pieces, and belongs to the technical field of construction equipment and facilities.
Background
An existing flat anchorage device is composed of a cover plate 2 with bolt holes 1 and a bottom plate 4, and a carbon fiber plate 3 is clamped between the cover plate and the bottom plate, as shown in fig. 1-3. The action principle is that after the bolt 5 is screwed down, the cover plate 2 and the bottom plate 4 apply pressure to the carbon fiber plate 3, and the applied prestress is balanced through the friction force generated between the carbon fiber plate 3 and the cover plate 2 and the bottom plate 4. However, the existing flat plate anchorage has the following disadvantages: the friction between the carbon fiber plate and the cover bottom plate depends on the pressure between the three, which comes from the tightening torque of the bolts. When the applied prestress is higher, the screwing force of the bolt needs to be larger, the cover plate and the bottom plate generate deflection, the pressure among the three is unevenly distributed, the pressure on two sides close to the bolt is larger, the corresponding friction force is larger, the middle pressure is smaller, and the corresponding friction force is smaller, namely, the friction force of the bottom plate and the cover plate on the transverse section of the carbon fiber plate is uneven, and the two sides are larger and the middle is smaller, as shown in fig. 4. Under the action of prestress, the carbon fiber plate is easy to slide out from the middle, and the two sides are still well clamped, so that splitting damage is generated.
SUMMERY OF THE UTILITY MODEL
Accordingly, it is an object of the present invention to overcome the above-identified deficiencies in the prior art and to provide a prestressed carbon fiber panel flat anchorage with clamping tabs.
In order to achieve the purpose, the prestressed carbon fiber plate flat anchorage device with the clamping piece comprises a cover plate and a bottom plate, wherein a carbon fiber plate can be clamped between the cover plate and the bottom plate; at least, be provided with the holding tank on the two of apron and bottom plate be provided with the clamping piece in the holding tank, one side of clamping piece is planar, and the opposite side is provided with first arcwall face, the tank bottom of holding tank be provided with first arcwall face matched with second arcwall face.

The bolt 5 holes 1 are distributed on two sides of the accommodating groove 6.
By adopting the technical scheme, the prestressed carbon fiber plate 3 flat anchor with the clamping piece 7 can overcome the defect of uneven transverse distribution of pressure on the contact surface of the anchor plate and the carbon fiber plate 3 in the prior art, can ensure that the friction force of the carbon fiber plate 3 is transversely uniformly distributed, and avoids splitting damage. The action principle is as follows: 1. the cross section of the anchor plate (the cover plate 2 and the bottom plate 4) within the range of the bolts 5 at both sides is arc-shaped, the rigidity is large in the middle, and both sides are small, compared with the existing flat anchorage device, under the action of the tensile force of the bolts 5 at both sides, the upper deflection in the middle is relatively small, and the pressure distribution of a contact surface is more uniform; 2. the pressure of anchor slab transmits carbon fiber plate 3 through middle clamping piece 7, and the pressure effect direction is perpendicular with the cambered surface between clamping piece 7 and the anchor slab, and the pressure effect direction is then perpendicular with carbon fiber plate 3 between clamping piece 7 and the carbon fiber plate 3. Through the two points, the uneven transverse distribution of the friction force on the surface of the carbon fiber plate 3 caused by the bending and the upward deflection of the anchor plate can be balanced.
