For addressing the above problem, the utility model provides a kind of FRP muscle bond type anchorage, comprise that anchor cylinder, nut and end are stifled, described anchor cylinder is provided with glue filling opening, and described anchor cylinder is connected with nut, and described anchor cylinder inside comprises concave section and flat segments, one end of described concave section is fixedly installed flat segments, described anchor cylinder two ends are provided with opening, and described opening is provided with that first end is stifled or the second end stifled, and stifled or the second end of described first end blocks and is provided with through hole.
As further improvement of the utility model, described anchor tube inner surface is provided with roughening processing layer, and described anchor tube outer surface is provided with screw thread, and described screw thread and nut are suitable.
As further improvement of the utility model, described nut is at least provided with one, and described anchor cylinder is at least provided with one.Described nut is provided with pin hole, and the inwall of described pin hole is provided with screw thread, and latch is installed in described pin hole.
As further improvement of the utility model, on the axis that is centered close to anchor cylinder that described first end is stifled or the second end is stifled.The distribution that is centrosymmetric of described first end through hole stifled or that the second end blocks.Described latch one end is provided with external screw thread, and described external screw thread and pin hole are suitable.
Compared with existing structure, the beneficial effects of the utility model are: make full use of the cementitiousness of single anchor cylinder to FRP muscle, in the situation that single anchor tube length degree is less (anchoring efficiency is now higher), connect anchor cylinder by nut, the concave section design of the inside of anchor cylinder is beneficial to the extruding (whole concave section simultaneously play a role) of colloid to muscle material, and extruding force is along muscle material length direction even variation, favourable to giving full play to of FRP muscle bearing capacity.Thereby obtain higher overall anchoring efficiency.
Structure design of the present utility model has the following advantages: ground tackle simple structure of the present utility model, and easy to use.Concave section design makes ground tackle inside occur continuous variable cross section, and this setting is beneficial to the formation (whole concave section plays a role simultaneously) of the extruding force of colloid to FRP muscle material, and extruding force is along muscle material length direction even variation, is beneficial to the performance of FRP muscle axial tension.

Detailed description of the invention
As shown in Fig. 1-7, a kind of FRP muscle bond type anchorage, comprises that anchor cylinder, nut and end are stifled, and anchor cylinder 1 is provided with glue filling opening 2, and its diameter need to be determined according to encapsulating.Adjacent anchor cylinder connects by nut 3, and anchor cylinder inside comprises concave section 4 and flat segments 5, and one end of concave section 4 is fixedly installed flat segments 5, and anchor cylinder interior shape is: flat segments+concave section.
Anchor cylinder two ends are provided with opening, and opening is provided with the stifled 6-1 of first end or the stifled 6-2 of the second end, and the stifled 6-1 of first end or the stifled 6-2 of the second end are provided with through hole 7.The left view of the stifled 6-1 of first end and the stifled 6-2 of the second end is shaped as disc, and the stifled 6-1 of first end or the stifled 6-2 brim-portion thickness of the second end are 3mm, and the thickness of mid portion is 6mm, and Duan Du center is provided with a through hole 7; Central Symmetry is arranged some through holes 7, and in order to FRP muscle material is located, through hole 7, than FRP muscle material slightly larger in diameter, can be determined according to FRP muscle material diameter.The stifled 6-1 of first end and the stifled 6-2 of the second end all establish 12 4 of screw holes, for holding stifled location.On the axis that is centered close to anchor cylinder of the stifled 6-1 of first end or the stifled 6-2 of the second end.
Anchor cylinder 1 inner surface is provided with roughening processing layer, and anchor cylinder 1 external surface is provided with screw thread 8, and screw thread 8 is suitable with nut 3.
