In view of the above-mentioned problems of the prior art, it is an object of the invention to provide a kind of inclined-plane anchor rod pallet board, the inclined-plane
After the installation of anchor pole support, after tightening nut, nut can completely attach to pallet, enough pretightning forces be produced to palisades supporting, together
When it is simple in construction, cost is relatively low.
To achieve the above object, the technical solution adopted by the present invention is：A kind of inclined-plane anchor rod pallet board, including anchor hole, pallet
Plane, the downwardly convex formation pallet inclined-plane of holding tray surface and joint face, joint face are bent to form downwards prestressing force face, prestressing force face
Bearing of trend is obtuse angle with angle formed by the bearing of trend of the holding tray surface.
Due to there is pallet inclined-plane on pallet, and the inclined-plane with holding tray surface at an angle, during installation, holding tray surface is close to
Palisades, in the anchor hole on anchor pole insertion pallet inclined-plane after, can be in the drilling of oblique insertion rock mass, while after tightening nut, nut
Side be bonded completely with anchor rod pallet board, stress concentration will not be produced, and enough pretightning forces can be produced to supporting.
Further, the pallet has certain elasticity.
Further, the pallet inclined-plane, which is closed on around anchor hole, an anchor ring relative to pallet ramp projections.
Further, in making or processing, the angle of pallet inclined-plane and holding tray surface can be adjusted greatly according to different situations
It is small.
Further, the pallet thickness is at least 8mm.
