Draw hole alignment, and cystosepiment 8 and baffle 9 are close together, and are clamped with U-shaped fastener 18 on jack and clamp system 11,
The U-shaped fastener 18 of the present embodiment is made of elastic metallic, and the distance between 18 liang of pinching ends of fastener are slightly smaller than cystosepiment 8
Then the distance merged with baffle 9, the one end not handled in main reinforcement by heading is sequentially passed through on cystosepiment 8
Reinforcing bar jack, draw hole on reinforcing bar jack and clamp system 11 on baffle 9；At this point, mechanism body 111 on clamp system 11
It is bolted with clamping element 112, but bolt is not tightened, main reinforcement 5 can be slided between clamp system draws hole；
（d）Apply the identical pretension of size to every main reinforcement using puller system, every main reinforcement after prestretching process is completed,
Main ribs are fixedly clamped using clamp system 11, after all main reinforcements complete prestretching process, stretch board 10 is rotated, makes tensioning
Fixed metallic rod is aligned with metallic rod fixed on clamp system 11 on plate 10, at this point, stretch board 10 is close in limited block 15
On, clamp system 11 and stretch board 10 are linked together to connected nut 14 using two-way, and fixed stretch board 10 with bayonet lock,
Locking nut 17 is screwed on after tensioning screw rod 16 fixed on stretch board 10 is passed through sealing plate 7, completes the dress of steel reinforcement cage and tensioning tool
Mould, and then prestressed stretch-draw is carried out to prestressing force main reinforcement 5.
After the completion of tensioning step, above-mentioned tensioning component does not take out, but as a part of component of pile pile, continue
Other steps of pile pile production are carried out, until producing pile pile finished product, in above-mentioned tensioning component, clamp system 11 and baffle 9
Between there are certain gaps, after pile pile is obtained, the extra reinforcing bar of end-plate-free one end is cut, formed 6cm long it is pre-
Stay end.
By understanding that this practicality is new to the introduction of the utility model structure that sheet pile tensioning has for no reason and method for stretching above
Type applies every reinforcing bar by puller system in reinforced bar stretching process the pretension of equal size, every to pull a reinforcing bar in advance
Drawn reinforcing bar is fixed on the clamp system afterwards, this causes the tensional state of every reinforcing bar to be consistent, right after pretreatment
All reinforcing bars carry out two times tensionings, and the reinforcing steel bar bear in stretching process is consistent, and greatly improves pile pile quality.
The above is only the preferred embodiment of the utility model patent, it is noted that for the general of the art
For logical technical staff, under the premise of the utility model patent principle is not departed from, several improvements and modifications can also be made, this
A little improvements and modifications also should be regarded as the protection domain of the utility model patent.
