Description
Technical field
The utility model is related to a kind of prestress steel twist wire-connecting devices, belong to steel strand wires technical field.
Background technology
The increasingly extensive industry that is applied to of prestressed anchorage technology is led with civil buildings, municipal road and bridge, mine roadway support
Domain, prestress steel twist wire-connecting device are most basic and most important component parts in anchoring system, and prestress wire connects
Whether connection device is effective, is related to the foundation of prestress system success, and importance is self-evident.For prestress steel twist
The fixation of line has two kinds of pre-tensioning system and post stretching, and the key of prestressing technique is anchor rod, and anchor rod is to ensure prestressing force
One of safe and reliable key of concrete structure, the stress of anchorage is uniform, when the engineering of prestressed concrete is long, mixed
Solidifying soil end stretch-draw prestressing force steel strand wires can cause larger loss of prestress, need to be segmented using prestress steel twist wiring connector
Stretch-draw prestressing force steel strand wires, to reduce the loss of prestress of prestressed concrete engineering.
At present, cause between the anchor and anchor ring of the anchored end of existing prestress steel twist wiring connector easily into cement mortar
Prestress wire anchored end clamping before tensioning and in stretching process is not tight, so as to cause prestress wire in stretching process
Pulled, influence the foundation of stretching force, existing prestress steel twist wiring connector in assembling process anchored end and connecting sleeve it
Between insufficient strength it is high, be easy to cause prestress wire and come off with connector, influence assembling quality and efficiency.Although existing
Technology in there is different devices to solve the above problems, but still can not plan bottom solve the problems, such as this.
Utility model content
In order to overcome the problems, such as that existing prestress wire attachment device clamps scarce capacity at present, the utility model carries
A kind of prestress steel twist wire-connecting device is supplied.
To solve the above problems, the utility model adopts the following technical solution：
A kind of prestress steel twist wire-connecting device is made of Extrusion anchor ground tackle, anchor ring, protection sleeve pipe.The Extrusion anchor ground tackle is fixed
It is sleeved on prestress wire, coarse arc convex item is set on the inside of Extrusion anchor ground tackle, and the coarse arc convex item part is fitted into
At prestress wire gap, the outside of Extrusion anchor ground tackle is equipped with anti-skidding rectangular strip, and high strong spring is set above anti-skidding rectangular strip,
High strong spring, which is fixedly connected, allows pressure pad block.The anchor ring is sleeved on the outside of Extrusion anchor ground tackle, and the anchor ring is by two semicircle anchors
Part forms, and semicircle anchor is internally provided with groove corresponding with anti-skidding rectangular strip, and the outside of semicircle anchor is equipped with coarse circle
Hemisphere jut.The protection sleeve pipe fixing sleeve sets coarse spheroidal protrusion inside the outside of anchor ring, protection sleeve pipe.
At least ten groups of the coarse raised item, the high strong spring at least set 15 groups, and the Extrusion anchor ground tackle is using soft
Matter metallic aluminium is made, and the anchor ring and protection sleeve pipe are made of low-carbon alloy steel, the Extrusion anchor ground tackle, anchor ring and protective case
Pipe is coated with erosion resistant coating.
The beneficial effects of the utility model are：A kind of prestress steel twist wire-connecting device provided by the utility model, can be right
Prestress wire connection is played the role of good.Coarse arc convex is set on the inside of the inside Extrusion anchor ground tackle of Extrusion anchor ground tackle
Item so that Extrusion anchor ground tackle is seamlessly connected with prestress wire, and allowing between prestress wire and Extrusion anchor ground tackle has stronger hold
Power is wrapped up in, and does not allow to be also easy to produce slip.By the spring set on the outside of Extrusion anchor ground tackle and allow anchor ring that pressure pad block can be ensured that
Tightening force can also make the anti-skidding rectangular strip on the outside of extruding anchor have the tension of bigger, and increase friction.By in anchor ring
Setting spheroidal protrusion increases frictional force on the inside of outside and protection sleeve pipe, is not likely to produce slip.Therefore, the utility model designs
Rationally, it is simple in structure, easy for construction, prestress wire can be effectively connected, realizes prestress wire segmentation blanking, segmentation
It draws, prestress wire subsection tension or the prestress wire segmentation being widely portable in prestressed reinforced concrete construction connect
It is long.
