Abstract
The utility model relates to a bridge prestress anchorage device which is applied to concrete prestress tension in a road bridge construction process. After the prestress anchorage device is locked and used, the prestress anchorage device is withdrawn when facilities are used repeatedly or dismounted. A traditional prestress anchorage device comprises an outer anchorage device sleeve and an inner anchorage device sleeve. After the traditional anchorage device is locked, the relative friction force between the outer sleeve and the inner sleeve is very large to enable anchorage withdrawing to be difficult, and the anchorage withdrawing rate by using anchorage withdrawing machinery is low. Furthermore, destructive anchorage withdrawing methods of fire welding cutting, steel saw cutting, blasting powder explosion and the like are usually used, so that the anchorage withdrawing cost is high, and the traditional anchorage device is basically damaged and cannot be used after anchorage withdrawing. The bridge prestress anchorage device comprises a sleeve (1), a carbon steel wire (2) is arranged in the sleeve, the carbon steel wire is connected with a conical screw (3), a base plate (4) is arranged on the conical screw (3), and the base plate is connected with a six-slot nuts (5). The bridge prestress anchorage device is used for anchoring a steel wire bundle.
Description
Technical field:
The utility model relates to a kind of bridge prestress ground tackle.
Background technology:
Prestressed anchor is applicable in the road and bridge engineering process of construction concrete pre-stress stretch-draw and uses, and after prestressed anchor locking is used, requires to reuse or facility requires prestressed anchor to move back anchor when removing.Traditional prestressed anchor comprises ground tackle overcoat and ground tackle inner sleeve, after the prestressed anchor locking since the relative friction forces of jacket and inner sleeve very large easily to cause moving back anchor very difficult, use the anchor restorer tool successfully to move back the anchor rate very low, often use destructiveness to move back anchor method such as fire weldering cutting, hacksaw cutting, gunpowder explosion etc., move back the anchor cost high and move back anchor after the damage of ground tackle sill can't utilize.
Summary of the invention:
The purpose of this utility model provides a kind of bridge prestress ground tackle.
Above-mentioned purpose realizes by following technical scheme:
A kind of bridge prestress ground tackle, its composition comprises: sleeve, in the described sleeve carbon steel wire is installed, described carbon steel wire is connected with conical screw, on the described conical screw backing plate is installed, and described backing plate is connected with six groove nuts.
Described bridge prestress ground tackle has steam vent on the described backing plate.
Described bridge prestress ground tackle, the diameter of described carbon steel wire are 5mm.
Beneficial effect:
Prestressed anchor simple structure, practicality that the utility model provides can be held so that realize moving back anchor very much.Can have short implementation cycle, characteristics that consolidation effect is good, and any change not occur almost the beam slab shape after the construction so that the active under certain operating mode of bridge concrete beam, plate is reinforced, the bridge outward appearance can be not destroyed yet.
Have steam vent on the described backing plate, state is firm.
The diameter of the carbon steel wire that uses is 5mm, has alleviated overall weight under the best is accepted state.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment:
Embodiment 1:
A kind of bridge prestress ground tackle, sleeve 1 is equipped with carbon steel wire 2 in the described sleeve, and described carbon steel wire is connected with conical screw 3, and backing plate 4 is installed on the described conical screw, and described backing plate is connected with six groove nuts 5.
Embodiment 2:
According to embodiment 1 described bridge prestress ground tackle, has steam vent 6 on the described backing plate.
Embodiment 3:
According to embodiment 1 or 2 described bridge prestress ground tackles, the diameter of described carbon steel wire is 5mm.
Claims (3)
1. bridge prestress ground tackle, its composition comprises: sleeve is characterized in that: in the described sleeve carbon steel wire is installed, described carbon steel wire is connected with conical screw, on the described conical screw backing plate is installed, and described backing plate is connected with six groove nuts.
2. bridge prestress ground tackle according to claim 1 is characterized in that: have steam vent on the described backing plate.
3. bridge prestress ground tackle according to claim 1 and 2, it is characterized in that: the diameter of described carbon steel wire is 5mm.
