Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, in the following with reference to the drawings and specific embodiments
Clear, complete description is carried out to utility model.
Existing pre-stressed carbon fiber plate anchorage technology, there are the anchorings of pre-stressed carbon fiber plate to loosen, bites broken, and anchoring property is steady
The problem of qualitative, poor reliability, develops a kind of pre-stressed carbon fiber plate wedge as shown in Figs. 1-3 in order to solve this problem
Shape anchorage comprising carbon fiber board 1, anchor set 2, wedge-shaped anchor slab 3, boss 4 and adhesive glue, the wedge shape anchor slab 3 and anchor set 2
Contact surface be spherical surface 6, wedge insert compatible with the wedge-shaped anchor slab 3, the wedge insert are provided on anchor set 2
Upper and lower end face be the spherical structure being recessed inwardly, the upper and lower end face of upper and lower two wedge-shaped anchor slabs 3 is the ball outwardly protruded
Face structure；Multiple boss 4 are symmetrically arranged on the stitching surface of the upper and lower two wedge-shaped anchor slabs 3, the wedge shape anchor slab 3
Stitching surface is coated with the adhesive glue 5, after upper and lower two 3 splits of the wedge-shaped anchor slab in the wedge insert of anchor set 2,
Boss 4 on the wedge shape anchor slab 3, which is laminated, is anchored at the carbon fiber board 1 in the anchor set 2.In the present embodiment, institute
The cross section rectangular and trapezoidal shapes of boss 4 are stated, the top surface of boss 4 forms seal face, and multiple seal faces that multiple boss 4 are formed can
Carbon fiber board 1 is effectively compressed, prevents carbon fiber board 1 from loosening.
As shown in Figure 1-3, the contact surface of wedge-shaped anchor slab 3 and anchor set 2 is spherical surface 6, reduce anchor set 2 because carbon fiber board 1 by
Power generate deformation and caused by stress concentrate, make wedge-shaped anchor slab 3 press when stress it is more balanced, strengthen anchoring stability,
Reliability；The tension small end excessive compression carbon fiber board 1 for avoiding two wedge-shaped anchor slabs 3, reduces the stress collection of carbon fiber board 1
In, increase the service life and reliability of carbon fiber board 1.The upper and lower end face of wedge insert is the spherical structure being recessed inwardly, on
The upper and lower end face of the lower two wedge-shaped anchor slabs 3 is the spherical structure outwardly protruded, and one end is big by one after two wedge-shaped anchor slabs 3 press
Hold small, the small end of two wedge-shaped anchor slabs 3 can be inserted into wedge insert by the big end of wedge insert, be drawn when applying to carbon fiber board 1
When the small extreme direction of power inward hole is drawn, two wedge-shaped anchor slabs 3 and the inner hole of wedge shape are conducive to the locking of 1 tension of carbon fiber board, avoid
The anchoring of carbon fiber board 1 loosens.
Four stupefied, wedge inserts that the wedge insert of wedge-shaped anchor slab 3 and anchor set 2 is in contact contacted with wedge shape anchor slab 3 four
