Abstract
The invention relates to a strand tapered anchorage for tension of a carbon fiber plate. The strand tapered anchorage comprises an anchor plate and a clamping piece, wherein the anchor plate is provided with a square hole for installing of the clamping piece, two extruded surfaces have a 1-5 degree dip angle, and the dip angle outside the clamping piece is greater than the corresponding dip angle on the anchor plate by 0.1-1 degree. Due to the inclination difference between the clamping piece and the anchor plate, after being installed in the anchor plate, the clamping piece bears uniform clamping force on the side surface, so that the problem that the carbon fiber plate breaks at the tip of the clamping piece due to stress concentration is solved, the carbon fiber plate is prevented from being damaged, and the anchoring effect of the anchorage is improved.
Description
Technical field
The present invention relates to the strand tapered anchorage that a kind of carbon fiber board stretch-draw is used, belong to carbon fiber board and strengthen technical field.
Background technology
That carbon fiber board has advantages of is lightweight, hot strength is large, is ideal reinforcing material.In the enhancing of steel construction piece, there is fabulous application prospect.
Strengthen steel work with carbon fiber board, need to the two ends of carbon fiber board be fixed with ground tackle, and then ground tackle is fixed on steel work, so ground tackle is a key technology in carbon fiber board enhancing technology.
As accompanying drawing 1, ground tackle used comprises anchor slab 1, intermediate plate 2 at present, and the inner surface of anchor slab 1 has certain inclination angle, and the external surface inclination angle of intermediate plate 2 is identical with the external surface inclination angle of anchor slab 1.With two intermediate plates 2, clamp carbon fiber board 3, be assembled in anchor slab 1, when stretching carbon fiber board 3, intermediate plate 2 is subject to the extruding of anchor slab 1, and carbon fiber board 3 is stepped up, and realizes the anchoring of carbon fiber board 3.
Because the inclination angle of intermediate plate and anchor slab is identical, intermediate plate easily comes off from anchor slab.And in processing, for the convenience of assembling, conventionally the inclination angle of anchor slab is done to such an extent that be slightly larger than the inclination angle of intermediate plate, so in use, the tip of intermediate plate is subject to larger extruding force, easily makes carbon fiber board be damaged.
Summary of the invention
The object of the invention is, for above-mentioned the deficiencies in the prior art, provides a kind of ground tackle, solves the problem of carbon fiber board in the fracture of the place, tip of intermediate plate.
Technical scheme of the present invention is as follows:
The ground tackle that carbon fiber board stretch-draw is used, comprises anchor slab and intermediate plate, and anchor slab is with the square hole that intermediate plate is installed, two of square hole are squeezed and wear the inclination angle of 1-5 °, intermediate plate is arranged in square hole, and the inclination angle in intermediate plate outside is 1.1-6 °, and the inclination angle of intermediate plate is than the large 0.1-1 ° of anchor slab.
As preferred version, the inclination angle of anchor slab is 1.5-2.5 °.
As preferred version, the inclination angle of intermediate plate is than the large 0.2-0.3 ° of anchor slab.
Beneficial effect is: intermediate plate has the inclination angle larger than anchor slab, intermediate plate is packed into after anchor slab, and side is subject to uniform chucking power, and carbon fiber board is not concentrated and the problem of generation fracture in the most advanced and sophisticated stress of intermediate plate, avoid the destruction to carbon fiber board, improved the anchoring effect of ground tackle.
Accompanying drawing explanation
The ground tackle sectional view that accompanying drawing 1 is prior art.
Accompanying drawing 2 is ground tackle sectional view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 2, the external form of anchor slab 21 is the cuboid of length 100mm, width 100mm, height 50mm, and centre is square hole, and the width 50-70mm of square hole is 20-30mm highly, and two of width 50-70mm are squeezed and wear the inclination angle of 2 °.The external form of intermediate plate 22 is cuboid, length 100mm, and outside is with the inclination angle of 2.5 °.
With intermediate plate 22, clamp carbon fiber board 23 and be assembled among anchor slab 21, after pretension, there is slight distortion in great Kou one end of anchor slab 21, and the face that is squeezed of intermediate plate 22 is formed to chucking power.Because the inclination angle of intermediate plate 22 is greater than the inclination angle of anchor slab 21, so the afterbody of intermediate plate is stressed larger, most advanced and sophisticated stressed smaller.Point stresses is concentrated and can be caused carbon fiber board 23 in tip fracture, causes ground tackle timeliness; And afterbody is stressed bigger, can not cause the problem of inefficacy.And under use state, anchor slab 21 continues distortion under stronger stretching action, the tip of intermediate plate 22 and afterbody can reach unanimity more to the chucking power of carbon fiber board 23.And anchor slab is bigger to the chucking power of intermediate plate afterbody, make intermediate plate more be not easy to come off, can reduce pretightning force, be conducive to assembly manipulation.
Compared with prior art, the inclination angle of this intermediate plate is greater than the scheme at the inclination angle of the intermediate plate installing hole of ground tackle, has solved the problem that fracture easily occurs at the tip of intermediate plate at carbon fiber board, has improved the anchoring effect of ground tackle.
The present invention can summarize with other the concrete form without prejudice to spirit of the present invention or principal character.Therefore, any change in implication and the scope suitable with claims of the present invention, all should think to be included in the scope of claims.
