The problem of relaxation and structural change etc. cause anchoring body system to destroy.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way:
A kind of steel strand wires end anchorage device, including the anchor disk and pedestal that arrangement and longitudinal section take the shape of the letter U outside in one, institute
It states between the bottom plate of anchor disk and the bottom plate of the pedestal there are gap, is both provided in the middle part of the bottom plate of the pedestal and anchor disk logical
Hole, steel strand wires one end are fixed on by horn socket on the bottom plate of the anchor disk, and the horn socket outer surface is tapered, the cone
Shape pipe sleeve inner surface is provided with internal thread, is reached after the through-hole for the bottom plate that the steel strand wires other end sequentially passes through anchor disk and pedestal
Below the bottom plate of pedestal;It is symmetrical arranged on the bottom plate of the anchor disk there are two bolt hole, adjustment bolt passes through the bolt hole simultaneously
The bottom plate for withstanding pedestal is set to the anchor with the adjusting nut of adjustment bolt cooperation and tries to get to the heart of a matter the lower end of plate;The two of the pedestal
It is symmetrical arranged there are two slotted hole on side plate, is provided with circular hole corresponding with the slotted hole on the side plate of the anchor disk, tightly
The side plate of the anchor disk and pedestal is fixed together by fixing bolt after passing through the circular hole and slotted hole.
Further, the horn socket upper end is provided with the retaining ring for compressing horn socket.
Further, the steel strand wires periphery between the anchor disk and pedestal is provided with protection pipe, outside the protection pipe
Side is provided with reinforcing rib in spiral distribution.
Compared with the existing technology, steel strand wires end anchorage device of the present invention has the advantage that:By using upper
Technical solution is stated, adaptability adjusting can be carried out to the prestressing force of steel strand wires, avoids the creep due to stratum, steel relaxation, structure
Steel strand prestress value caused by variation etc. changes, and to enhance the stability of anchoring body system, ensures the peace of building, bridge
It is complete to stablize.

Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood by concrete condition
Concrete meaning in the present invention.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in Figs 1-4, a kind of steel strand wires end anchorage device, including arrangement and longitudinal section take the shape of the letter U outside one in one
Anchor disk 1 and pedestal 2, there are gap between the bottom plate and the bottom plate of the pedestal 2 of the anchor disk 1, the pedestal 2 and anchor disk 1
It is both provided with through-hole in the middle part of bottom plate, 10 one end of steel strand wires is fixed on by horn socket 6 on the bottom plate of the anchor disk 1, the taper
6 outer surface of pipe sleeve is tapered, and 6 inner surface of the horn socket is provided with internal thread, and 10 other end of the steel strand wires sequentially passes through
Below the bottom plate for reaching pedestal 2 after the through-hole of the bottom plate of anchor disk 1 and pedestal 2;
Further, 6 upper end of the horn socket is provided with the retaining ring 7 for compressing horn socket 6;
Further, the steel strand wires periphery between the anchor disk 1 and pedestal 2 is provided with protection pipe 8, the protection pipe
8 outsides are provided with reinforcing rib 9 in spiral distribution;
It is symmetrical arranged on the bottom plate of the anchor disk 1 there are two bolt hole, adjustment bolt 4 passes through the bolt hole and withstands base
The bottom plate of seat 2, the adjusting nut 5 coordinated with adjustment bolt 4 are set to the lower end of 1 bottom plate of anchor disk;
It is symmetrical arranged there are two slotted hole 201 on the both side plate of the pedestal 2, is provided on the side plate of the anchor disk 1
Circular hole corresponding with the slotted hole 201, fastening bolt 3 is after the circular hole and slotted hole 201 by the anchor disk 1 and pedestal
2 side plate is fixed together;
The course of work of this example:When creep, steel relaxation, the structural change etc. due to stratum cause steel strand prestress
When value variation, adjustment bolt 4 and other fastening bolts 3 are loosened, are then adjusted using the correspondence of slotted hole 201 and circular hole
The relative position of anchor disk 1 and pedestal 2 ensures the stabilization of steel strand prestress value, after adjusting, tightens fastening bolt 3 and adjustment
Bolt 4.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
