Referring to fig. 15, 16 and 17, the bar guide in this embodiment mainly includes a guide roller 022, a guide roller frame 021 and a bracket 023. Wherein, wire roller 022 sets up on wire roller frame 021, and wire roller frame 021 sets up on support 023, and wire roller 022 includes vertical roller 0221 and the horizontal roller 0222 of level setting that sets up of setting, and vertical roller is used for restricting the side-to-side movement of reinforcing bar, and horizontal roller is used for restricting the up-and-down motion of reinforcing bar. The number of the horizontal rollers 0222 is two, and the horizontal rollers 02221 and the lower horizontal roller 02222 are respectively provided, the upper horizontal roller 02221 and the lower horizontal roller 02222 are vertically disposed, the number of the vertical rollers 0221 is at least three, the vertical rollers 0221 are disposed side by side on the guide roller frame 021, and the upper horizontal roller 02221, the lower horizontal roller 02222 and the vertical rollers 0221 jointly form two or more guide openings through which the reinforcing bars 024 pass.
The reinforcing bar guider that this embodiment provided, its course of work is: when the prestressed laminated slab is released, workers respectively pass each strand of steel bars through a closed guide opening formed by the transverse rollers 0222 and the longitudinal rollers 0221 so as to achieve that each strand of steel bars is respectively distributed in a relatively independent guide space. At the moment, the steel bars passing through the guide device are fixed on the tensioning equipment, and are paid off along the production line. Under the action of the guide device, the multiple strands of reinforcing steel bars are smoothly paid out along the respective guide areas.
Utilize the horizontal roller 0222 and the vertical roller 0221 that set up on wire roller frame 021 to constitute two or two more reinforcing bar guiding openings jointly, horizontal roller 0222 and vertical roller 0221 make the reinforcing bar frictional force when the unwrapping wire reduce, and the reinforcing bar quantity of reinforcing bar guiding opening stretch-draw as required sets up, and a guiding opening corresponds a reinforcing bar to the mutual wearing and tearing of reinforcing bar that exists when having solved the common unwrapping wire of stranded reinforcing bar problem of interfering.
Wherein, reserve a plurality of mounted positions of vertical roller 0221 at certain distance interval on wire roller frame 021, when the reinforcing bar is arranged or the reinforcing bar that waits to stretch-draw and present vertical roller 0221 position mismatch, can increase vertical roller 0221, perhaps move vertical roller 0221.
Because in reinforcing bar processing production process, have other construction equipment work on the construction site, often need reduce reinforcing bar guiding device's height and dodge.
According to this embodiment, the support 023 in the above scheme is preferably a liftable support 023. The liftable bracket 023 drives the wire guide roller frame 021 to reduce the height, so that other construction equipment can be ensured to safely pass through.
According to this embodiment, the support 023 includes a guide sleeve and a guide shaft, which are vertically disposed, the guide sleeve is sleeved on the guide shaft, and the guide sleeve and the guide shaft can move telescopically along the vertical direction. The support 023 can also be provided with a lifting power device 026, the lifting power device 026 is one of an oil cylinder, an air cylinder or a screw rod, and the lifting power device 026 is used for driving the support 023 consisting of the guide sleeve and the guide shaft to extend.
The lifting power device 026 can be disposed in the guide sleeve and the guide shaft to directly push the guide sleeve and the guide shaft to extend or be disposed outside the guide sleeve and the guide shaft to directly push the guide roller frame 021 to lift. For example, the lifting power device 026 is a scissor jack.
In addition, the support 023 may not be provided with a guide shaft and a guide sleeve, or even with a lifting mechanism, referring to fig. 18, a hinge device 028 may be provided at the lower end of the support 023, and the support 023 may be rotated and laid down around the hinge device 028.
In order to guarantee that support 023 puts after more steady, prevent that reinforcing bar guider from damaging, can preferably set up the support and sit on support 023, hinge means 028's top, support 023 puts down the back, and support seat 027 provides the support for support 023.
On the other hand, the invention also provides a prestressed reinforcement integral paying-off method, which comprises the following steps:
a, leading out at least two steel bars from a pay-off device;
b, the reinforcing steel bars pass through reinforcing steel bar guiding devices, and each reinforcing steel bar is independently guided by the reinforcing steel bar guiding devices;
c, leading the steel bars passing through the steel bar guiding device to a wire pulling trolley, and respectively clamping the steel bars by a clamping device of the wire pulling trolley;
d, starting the wire pulling trolley traveling device to drive the wire pulling trolley to move to the final tensioning anchoring end, and stopping the wire pulling trolley;
further, the method also comprises the following steps after the step D:
e, loosening a clamping device of the wire pulling trolley, placing the reinforcing steel bars at the final tensioning anchoring end, and anchoring the reinforcing steel bars at the final tensioning anchoring end;
