A kind of basalt fibre bar stretching and anchoring device, including basalt fibre muscle, the end of basalt fibre muscle is provided with overstriking portion, the outer circumference surface in overstriking portion is provided with the basalt fibre muscle overstriking section protrusion of surface of some rules, the outer section in overstriking portion is provided with umbrella shape termination, umbrella shape termination is protruded to the direction away from basalt fibre muscle, and umbrella shape termination is depression on the direction of basalt fibre muscle；Overstriking portion and umbrella shape termination are respectively positioned in steel anchor ring, steel anchor ring endoporus is shaped as inner conical surface in the middle part of basalt fibre muscle, having some rules hemispheric steel anchor ring inner conical surface projection on inner conical surface, the endoporus away from basalt fibre muscle is circular, which is provided with front end female thread；
The expandable epoxy mortar solidified after being provided with perfusion between overstriking portion and the umbrella shape termination of steel anchor ring and basalt fibre muscle, the outer surface of epoxy resin mortar is identical with the bore section being shaped as inner conical surface of steel anchor ring, and the inner surface of epoxy resin mortar coincide with the overstriking portion of basalt fibre muscle and the external surface shape of umbrella shape termination。
The manufacture method of above-mentioned basalt fibre bar stretching and anchoring device, comprises the following steps:
On the end of basalt fibre muscle, melting basalt fibre muscle in the mould with surface hemisphere groove, mould internal diameter is 10-12 times of basalt fibre muscle diameter, removes mould after cooling, basalt fibre muscle end diameter increases, and its surface forms the hemispheric projection of some rules simultaneously；
Meanwhile, arranging umbrella shape mould in the outer end of basalt fibre muscle, in umbrella shape mould inner pressure system after the thawing of basalt fibre muscle, after removing mould, its end forms umbrella shape；
Outer end is formed umbrella shape, process adds bulk processing, the basalt fibre muscle of the regular projection in surface is placed on endoporus and has inner conical surface, having in the steel anchor ring of some rules hemispheric basalt fibre muscle overstriking section protrusion of surface on inner conical surface, in anchor ring, enhancing perfusion has the epoxy resin mortar expanding function。
The invention has the advantage that and has the benefit effect that
Owing to the invention adopts technique scheme, umbrella shape termination, basalt fibre muscle end is utilized to be cut, pressurized, the cohesive force between the overstriking portion of end and epoxy resin mortar and the shearing force between regular hemispheric basalt fibre muscle overstriking section projection, steel anchor ring inner conical surface projection and epoxy resin mortar play anchorage effect；And, epoxy resin mortar expands can increase self compaction rate, basalt fibre muscle end radial stress can be increased, ensureing to pour into epoxy resin mortar degree of compaction while, shear ability between cohesive force, regular hemispheric basalt fibre muscle overstriking section protrusion of surface, steel anchor ring inner conical surface projection and epoxy resin mortar between increase basalt fibre muscle and epoxy resin mortar, thus improving anchoring ability。
