Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below embodiment of the present invention is made the most detailed
Thin description.
The present invention solves that technical problem present in known technology provides a kind of prestressed reinforced concrete construction chord to prop up structure
The wide-angle intermediate plate clipping anchorage of type CFRP muscle used, this anchorage can anchor horizontal enhancement mode CFRP muscle effectively, and
This anchorage small volume, easy to use, there is bigger versatility, see Fig. 1 to Fig. 5, described below:
A kind of intermediate plate clipping anchorage of type CFRP muscle, is mainly used in wide-angle intermediate plate type CFRP muscle, including: outside metal
Shell 1, pretension pressing plate 2, wedge shape intermediate plate 3, soft metal protection set 4, shrouding 5 and spring 6.
Wedge shape intermediate plate 3 is arranged in metal shell 1, and the CFRP muscle being socketed with soft metal protection set 4 penetrates wedge shape intermediate plate 3
In, pretension pressing plate 2, for depressing wedge shape intermediate plate 3, plays the effect that CFRP muscle applies pretightning force；Shrouding 5 pierces into gold
Belong to shell 1 to fix.
Wherein, metal shell 1 is rectangle, and the inclined plane angle inside the right and left is 6 °～10 °, is provided with intermediate plate location bar
Groove 1-1, shrouding detent 1-2 and pressing plate rod aperture (not shown).The angle of inclination of intermediate plate location bar groove 1-1
It is 6 °～10 °, in pressing plate rod aperture, sets screw thread.
Pretension pressing plate 2 includes pressing plate bar 2-1 and two parts of pressing plate 2-2, and pressing plate 2-2 is highly less than or equal to 5mm, pressing plate
Being threaded (pressing plate bar 2-1 passes pressing plate rod aperture) outside bar 2-1, pressing plate bar 2-1 end is provided with connector, for even
Connect spanner and apply pretightning force, after having applied pretightning force, remove spanner.
Wedge shape intermediate plate 3 is two-piece type, and including intermediate plate location bar 3-1 and two parts of intermediate plate 3-2, intermediate plate 3-2 lateral surface inclines
