Description
Technical field
The present invention relates to anchorage technical field, in particular to a kind of prestressed anchor.
Background technology
At present, what Bridges in Our Country prestressed anchor used is all that common steel strand wires strand tapered anchorage i.e. anchor ring is with intermediate plate
Version, cause whole prestressed structure to lose efficacy to prevent prestress wire from slipping from intermediate plate, traditional porous
Anchorage is to add a pressing plate at the first end of anchor ring to limit, but owing to pressing plate limiting structure is unstable, thus this biography
The presser type ways to restrain of system can not meet the purpose preventing prestress wire from slipping from intermediate plate.
Summary of the invention
It is an object of the invention to provide a kind of prestressed anchor, to solve the deficiencies in the prior art.
For realizing the object of the invention, the technical scheme of employing is:
A kind of prestressed anchor, it is characterised in that include that base plate, described base plate upper end are rotatably provided with cylinder, cylinder lower end is solid
Surely large bevel gear it is arranged with；Described large bevel gear is connected by thrust ball bearing with base plate；Anchor cup, anchor cup it is provided with in described cylinder
Periphery be connected by threaded engagement with the inner headed face of cylinder；The hollow-core construction of described anchor cup is lower big little taper seat,
Anchor cup hollow in be provided with intermediate plate, the outer surface of intermediate plate coordinates with the taper seat of anchor cup；The bottom surface of described intermediate plate and contacts baseplate
Coordinate；Described base plate offers through hole；Described base plate upper end is provided with housing, and the side of housing is rotatably provided with cone pinion, and
Cone pinion is connected with large bevel gear.
The invention has the beneficial effects as follows:
One, without by jack, directly twist cone pinion by spanner, tension of prestressed tendon, stress regulation can be carried out
And put.The conversion of big cone pinion is arranged, it is simple to the regulation of stress, can reach the proof stress error effect less than 0.5%
Really, the anchoring precision being greatly improved, it is ensured that test requirements document.Without ultra stretching, under original stress level, twisted by spanner
Cone pinion, can open putting with tensioned prestressing bar.The present invention is easy to operate, precision is high, economical and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the prestressed anchor that the present invention provides.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the present invention is described in further detail.
The prestressed anchor that the present invention that Fig. 1 is shown provides, including concrete 1, steel strand wires 8, base plate 2, thrust ball axle
Hold 3, large bevel gear 4, cylinder 5, anchor cup 6, housing 7, intermediate plate 9 and cone pinion 10.Described base plate 2 upper end is rotatably provided with cylinder
5, cylinder 5 lower end fixed cover is provided with large bevel gear 4；Described large bevel gear 4 is connected by thrust ball bearing 3 with base plate 2；Described circle
Being provided with anchor cup 6 in cylinder 5, the periphery of anchor cup 6 is connected by threaded engagement with the inner headed face of cylinder 5；The hollow knot of described anchor cup 6
Structure is lower the least big taper seat, anchor cup 6 hollow in be provided with intermediate plate 9, the outer surface of intermediate plate 9 coordinates with the taper seat of anchor cup 6；
The bottom surface of described intermediate plate 9 contacts cooperation with base plate 2；Described base plate 2 offers through hole；Described base plate 2 upper end is provided with housing 7, shell
The side of body 7 is rotatably provided with cone pinion 10, and cone pinion 10 is connected with large bevel gear 4；Described base plate 2 is fixed on
On concrete 1, steel strand wires 8 coordinate through the through hole of base plate 2 with intermediate plate.
Without by jack, directly twist cone pinion 10 by spanner, tension of prestressed tendon, stress tune can be carried out
Save and put and open.The conversion of big cone pinion is arranged, it is simple to the regulation of stress, can reach the proof stress error effect less than 0.5%
Really, the anchoring precision being greatly improved, it is ensured that test requirements document.Without ultra stretching, under original stress level, twisted by spanner
Cone pinion, can open putting with tensioned prestressing bar.The present invention is easy to operate, precision is high, economical and practical.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
