Abstract

Provided is a prestressed anchorage device used for road and bridge construction. The anchorage device is a permanent anchor device used in prestressed concrete, is an anchorage tool which is used for keeping pull force of prestressed ribs and transmitting the pull force into the concrete in a post-tensioned structure or component, and is also called the prestressed anchorage device. However, clamping performance of an anchorage device used in the prior art is not stable, and construction operations are complicated. The prestressed anchorage device comprises an oil cylinder (1), a piston (2) is arranged in the oil cylinder and connected with a tool anchor (3), the oil cylinder is connected with a limiting plate (4) which is connected with an anchor bearing plate (5), and the outside of the anchor bearing plate is provided with spiral ribs (6). The prestressed anchorage device is used as a steel strand anchorage device.

Description

Road bridge construction prestressed anchor
Technical field:
The utility model relates to a kind of road bridge construction prestressed anchor.
Background technology:
Ground tackle is permanent anchor device used in the solidifying soil of prestressing force, is in post stretching structure or member, for the pulling force of maintenance presstressed reinforcing steel and with its anchoring instrument that is delivered to inside concrete, also is referred to as prestressed anchor.
Permanent anchor device used on concrete.Ground tackle can be divided into two classes: (a) stretching end ground tackle: be arranged on the presstressed reinforcing steel end and can open ground tackle and also be referred to as prestressed anchor, so-called ground tackle is in post stretching structure or member, for the pulling force that keeps presstressed reinforcing steel and it is delivered to the mixed ground tackle that draws; (b) fixed end ground tackle: be arranged on the presstressed reinforcing steel end, usually in Transducers Embedded in Concrete and not in order to the ground tackle of stretch-draw.
But the gripping performance of the ground tackle that uses at present is unstable, and constructing operation is complicated.
Summary of the invention:
The purpose of this utility model is to provide a kind of road bridge construction prestressed anchor.
Above-mentioned purpose realizes by following technical scheme:
A kind of road bridge construction prestressed anchor, its composition comprises: oil cylinder is equipped with piston in described oil cylinder, described piston is connected with moveable anchor, described oil cylinder is connected with limiting plate, and described limiting plate is connected with anchor plate, and described anchor plate outside is equipped with spiral bar.
Described road bridge construction prestressed anchor is separately installed with work clip sheet on described moveable anchor, described work anchor slab, and described work clip sheet passes steel strand.
Beneficial effect:
The utlity model has well in the anchor performance, the intermediate plate follow-up is concordant, and gripping performance is stable, and constructing operation is easy.The lathe turner is easy to operate.Efficiency of anchorage is high, and anchoring property is stable, reliable.Has the repeat stretch-draw performance and than the strong anti-interference performance.
Steel hinge line of the present utility model is arranged in work clip sheet, realizes the clamping to steel strand, then by being arranged on the movement of in-oil cylinder piston, realizes the anchoring to steel hinge line.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment:
Embodiment 1:
A kind of road bridge construction prestressed anchor, its composition comprises: oil cylinder 1 is equipped with piston 2 in described oil cylinder, described piston is connected with moveable anchor 3, described oil cylinder is connected with limiting plate 4, and described limiting plate is connected with anchor plate 5, and described anchor plate outside is equipped with spiral bar 6.
Embodiment 2:
Road described according to embodiment 1 bridge construction prestressed anchor is separately installed with work clip sheet 7 on described moveable anchor, described work anchor slab, and described work clip sheet passes steel strand 8.
