Description
Technical field
The utility model belongs to bridge construction technical field of auxiliary equipment, more particularly to a kind of concrete Simple T-Girders
Drawing jack hanger.
Background technology
Pre-stressed concrete simple-support T-sectional girder is widely used in China railways engineering field.Prestressing stretching technique is
The critical process of precast beam production.During tensioning construction, it is that loading machine coordinates that traditional jack, which hangs shifting method,
Tripod directly coordinates completion with straddle truck, but this method in operation is easy to that beam body and steel strand wires are caused to damage,
Potential safety hazard is bigger, and needs when moving to take substantial amounts of mechanical one-shift, human resources, therefore the pole not side that constructs
Just, while also it is unfavorable for the saving of the energy.
The content of the invention
In order to solve the above problems, the purpose of this utility model is to provide a kind of light, safe and can repeat profit
With being moved easily the concrete Simple T-Girders tensioning jack hanger of operation.
In order to achieve the above object, concrete Simple T-Girders tensioning provided by the utility model includes horizontal stroke with jack hanger
Beam, two pieces of baffle plates, combination movable pulley, two supporting legs, annulus and steel wire rope；Wherein two supporting legs are set in splayed, upper end point
The on both sides of the middle position of crossbeam is not connected to；Combination movable pulley is arranged in the horizontal stroke of supporting leg junction side in a sliding manner
Liang Shang, for connecting jack by jack；Annulus is fixed on crossbeam on the end bottom surface of supporting leg junction opposite side；
Two pieces of baffle plates are separately fixed at the both ends of crossbeam, for preventing that combining movable pulley outwards skids off crossbeam；The middle part of steel wire rope is run through
In annulus, both ends are separately fixed on bridge floor exposed B1 reinforcing bars and T-steel.
Described combination movable pulley includes U-shaped frame and two rollers, wherein U-shaped frame surround the two sides that are arranged on crossbeam and
Outer side bottom surface, two rollers are arranged on the opening of U-shaped frame, and the outer circumference surface of roller is in contact with the top surface of crossbeam.
Described crossbeam uses 120*74*5mm I-steel；Supporting leg uses 100*48*5.3mm channel-section steels.
Concrete Simple T-Girders tensioning provided by the utility model jack hanger, which has, to be made simply, and installation, dismounting make
With convenient, production cost is low, can reuse, it is environmentally friendly the advantages that, therefore be easy to promote the use of.
Brief description of the drawings
Fig. 1 is concrete Simple T-Girders tensioning jack hanger front view provided by the utility model.
Fig. 2 is concrete Simple T-Girders tensioning jack hanger top view provided by the utility model.
Fig. 3 is concrete Simple T-Girders tensioning jack hanger side view provided by the utility model.
Embodiment
Concrete Simple T-Girders tensioning provided by the utility model is hung with jack with specific embodiment below in conjunction with the accompanying drawings
Frame is described in detail.
As shown in Fig. 1-Fig. 3, concrete Simple T-Girders tensioning provided by the utility model includes crossbeam with jack hanger
1st, two pieces of baffle plates 2,3, two supporting legs 4 of combination movable pulley, annulus 5 and steel wire rope 6；Wherein two supporting legs 4 are set in splayed, on
End is connected to the on both sides of the middle position of crossbeam 1；Combination movable pulley 3 is arranged in the junction of supporting leg 4 in a sliding manner
On the crossbeam 1 of side, for connecting jack by jack；Annulus 5, which is fixed on crossbeam 1, is located at the junction opposite side of supporting leg 4
End bottom surface on；Two pieces of baffle plates 2 are separately fixed at the both ends of crossbeam 1, for preventing that combining movable pulley 3 outwards skids off crossbeam 1；
The middle part of steel wire rope 6 is applied in annulus 5, and both ends are separately fixed on bridge floor exposed B1 reinforcing bars and T-steel.
Described combination movable pulley 3 includes U-shaped frame 7 and two rollers 8, and wherein U-shaped frame 7 surrounds and is arranged on the two of crossbeam 1
Side and outer side bottom surface, two rollers 8 are arranged on the opening of U-shaped frame 7, and the top surface of the outer circumference surface of roller 8 and crossbeam 1
It is in contact.
Described crossbeam 1 uses 120*74*5mm I-steel.
Described supporting leg 4 uses 100*48*5.3mm channel-section steels.
Now concrete Simple T-Girders tensioning provided by the utility model is illustrated such as with jack hanger installation and application method
Under：Concrete Simple T-Girders tensioning provided by the utility model is placed on bridge floor with jack hanger by operating personnel first, and
Supporting leg 4 is stood in the position for being more than 200mm away from beam-ends, then the both ends of steel wire rope 6 are locked in bridge floor respectively with snap ring exposed
On B1 reinforcing bars and T-steel, until steel wire rope 6 is in tensioned state, now crossbeam 1, afterwards will combination just at horizontal level
Movable pulley 3 moves to the close position of baffle plate 2 in the outer end of crossbeam 1, is connected finally by jack by movable pulley 3 is combined with stretch-draw jack
Connect, you can complete installation process.
Application method is：Will with jack hanger using jack and concrete Simple T-Girders tensioning provided by the utility model
Stretch-draw jack is promoted to duct horizontal level to be tensioned, i.e. tension steel strand beam position, the erector successively on steel wire bundle
Make anchorage, work clip sheet, limiting plate and gasket ring, mobile combination movable pulley 3, be installed in place stretch-draw jack and be close to gasket ring,
Installation tool anchorage, tool clamping piece are then proceeded to, finally adjustment combination movable pulley 3 and jack, make in anchorage center, jack
The heart, duct center point-blank, urgent work clip sheet, you can carry out tensioning operation.After the completion of tensioning operation, by opposite
Order is dismantled, and then moves to next duct, and constructed according to the method described above.
