Abstract
The utility model belongs to building machinery technical field prestressed stretch-draw equipment, more particularly to one kind can be used in turn anchor pole tension tool, and this anchor pole tension tool that is used in turn includes strand tapered anchorage, steel bushing, steel strand wires；Steel bushing is internally provided with taper anchor hole, rear portion is equipped with the internal thread being connect with anchor pole and steel bushing baffle；Strand tapered anchorage shape is cone, and strand tapered anchorage maximum outside diameter is more than taper anchor hole minimum diameter, and strand tapered anchorage is internally provided with the through-hole to match with steel strand wires, and through-hole wall is equipped with anti-skid chequer.The utility model solves the problems, such as that traditional steel bushing stretches position access times and excessively causes abrasion so that tensioning is from reaching requirement using strand tapered anchorage, steel bushing also solves the problems, such as to have enough to meet the need when strand tapered anchorage exclusive use simultaneously, the frictional force between strand tapered anchorage and steel strand wires is increased using anti-skid chequer inside strand tapered anchorage, steel strand wires is enable to bear the pulling force of bigger and then increases the range of stretch of anchor pole.
Description
Technical field
The utility model belongs to building machinery technical field prestressed stretch-draw equipment, more particularly to one kind can be used in turn anchor
Bar tension tool.
Background technology
Anchorage, fixture and connector are a kind of devices for anchoring and connecting presstressed reinforcing steel.After anchorage is mainly used in
In the method for opening construction, it is anchored at component ends and is used for keeping presstressed reinforcing steel pulling force and passing it in concrete, be permanent
Anchor.Fixture is also known as moveable anchor for post-tensioned construction, is the device that the stretching force of jack is transmitted to presstressed reinforcing steel.
Fixture is used in pre-tensioning system, and presstressed reinforcing steel is clamped during tensioning and concrete formation, to keep presstressed reinforcing steel pulling force and incite somebody to action
It is fixed on stretching bed seat, is reusable anchor.It anchor and can be also used interchangeably sometimes with fixture.Connector is used
In continuous structure, multistage presstressed reinforcing steel can be connected into an elongated long beam, to reach piecewise tensioning, connect, subtract paragraph by paragraph
Small friction loss makes the stress that presstressed reinforcing steel generates in total tend to be uniform, and saves the purpose of steel.
There are two types of methods for the anchorage and connector used when applying prestressing force for bar reinforcement at present：A kind of use and anchor cable
The fixation anchorage to match locks deformed bar by fixed anchorage, and fixed anchorage can not take out；Another can to use
To make the connector of turnover movement, this connector includes the internal steel bushing being threaded, the prestressing force being connected with steel bushing
Reinforcing bar and screw head, tensioning equipment carry out tensioning by tension reinforcing steel bar head to deformed bar.When using tension reinforcing steel bar head method
Deformed bar elasticity modulus is small compared with steel strand wires, and the deformation of stretching process deformed bar is big, can not ensure effective tensioning as a result, and
And when using this kind of method to certain number, screw head grinds with steel bushing junction screw thread and then causes shadow to connection reliability
It rings, therefore this connector access times are than relatively limited.
Utility model content
In the presence of solving the problems, such as background technology, the utility model proposes one kind being used in turn anchor pole tensioning work
Tool.
What the technical solution of the utility model was realized in：It includes clip type that one kind, which can be used in turn anchor pole tension tool,
Anchorage, steel bushing, steel strand wires；Steel bushing is internally provided with taper anchor hole, rear portion is equipped with the internal thread and steel bushing being connect with anchor pole
Cylinder baffle；Strand tapered anchorage shape is cone, and strand tapered anchorage maximum outside diameter is more than taper anchor hole minimum diameter, strand tapered anchorage
It is internally provided with the through-hole to match with steel strand wires, through-hole wall is equipped with anti-skid chequer.
The hole of the strand tapered anchorage is equipped with internal thread, and steel strand wires one end is equipped with external screw thread, and strand tapered anchorage is twisted with steel
Line is threadedly coupled.
The strand tapered anchorage and taper anchor hole contact site are smooth.
The utility model solves traditional steel bushing stretching position access times using strand tapered anchorage and excessively causes to wear
Prevent the problem of tensioning is from reaching perfect condition, while when steel bushing also solves strand tapered anchorage exclusive use, can not have enough to meet the need
The problem of, inside strand tapered anchorage using anti-skid chequer or setting and the internal thread that steel strand wires match increase strand tapered anchorage with
Frictional force between steel strand wires enables steel strand wires to bear the pulling force of bigger and then increases the range of stretch of anchor pole.
