The tensioning screw holes 12 and the steel bar anchoring holes 11 are independent and are not connected in series. When the end of the main bar 2 freely passes through the reinforcing bar anchoring hole 11 of the end plate, since the reinforcing bar anchoring hole 11 is not communicated with the tension screw hole 12, and is independent of each other, the main bar 2 does not run into the tension screw hole 12. The reinforcement anchoring hole 11 includes a through hole for penetrating the reinforcement cage main bar 2 and a counter bore for embedding the pier head of the reinforcement cage main bar 2 in the counter bore for fixing.

The shapes of the through holes and the counter bores in the steel bar anchoring hole 11 are not limited to 90-degree crossed arrangement of the kidney-shaped through holes and the kidney-shaped counter bores, 60-degree uniform crossed arrangement of the three kidney-shaped through holes and the three kidney-shaped counter bores and 45-degree uniform crossed arrangement of the two kidney-shaped through holes and the two kidney-shaped counter bores are all suitable for the method, as shown in fig. 6 and 8. The waist-shaped through hole and the waist-shaped counter bore are cross-shaped and cross-shaped, so that the T-shaped main rib upsetting head can penetrate into the end plate through the waist-shaped through hole and is clamped into the waist-shaped counter bore after self-rotation for 90 degrees. The tensioning screw holes 12 may also be arranged in the area between the two sets of cross holes 101, independent of each other, and not in series. As shown in fig. 10, the center line of the tension screw hole 12 and the steel bar anchoring hole 11 of the present invention may be coincident with the center line of the steel bar anchoring hole 11, and the steel bar anchoring hole 11 may include the through hole and the counter bore described above, or the steel bar anchoring hole 11 may be tapered, and the taper angle β thereof is 20 ° to 180 °. When the steel bar anchoring hole 11 is tapered, the pier head of the main steel bar 2 is also tapered, and is consistent with the shape of the steel bar anchoring hole 11, so that the pier head of the main steel bar 2 is conveniently embedded in the steel bar anchoring hole 11.

The number of the stretching screw holes 12 is 0.5 to 2 times of the number of the cross-shaped through holes/counter holes.

As the welding head 306 drives the spiral rib 204 to weld on the surface of the main rib 201 of each T-shaped upsetting head, the welding process of the reinforcement cage is gradually completed.

The small wheels of the tractor 301 are provided with encoders, the count value of the encoders is calculated by the controller, and the distance between the head end plate 1 and the tail end plate 4 of the tractor can be automatically calculated. When the tractor 301 is operated to the initial position, i.e. the position where the roll welding of the reinforcement cage is started, the encoder count is cleared, and after the roll welding is started, the tractor 301 is moved forward, i.e. away from the weld head mount 305. Along with the longer and longer distance, the count value of the encoder is larger and larger, and the tail end plate locking cylinders 3034 are fully retracted until the count length is about to reach the preset length, the tail end plate locking blocks 3035 at the head ends of the tail end plate locking cylinders 3034 are separated from the inner ring of the tail end plate 104, and as most of the reinforcement cages in the front are welded, the reinforcement cages have certain strength, the upsets of the T-shaped upsets main ribs 201 drive the tail end plate 104 to be separated from the copper plate 3036, so that the welding manufacture of the whole reinforcement cage is realized.

After the spiral rib is roll welded on the main rib for a plurality of circles, the angle of the T-shaped head of the main rib is firm and irreversible, and the rolling welding is completed along with the T-shaped head of the tail of the main rib entering the waist-shaped counter bore of the tail end plate 4, so that the reinforcement cage 2 and the end plate form a stable assembly.

And separating the tractor and the copper disc base from the head end plate 1 and the tail end plate 4 respectively to form a reinforcement cage finished product.
