The first direction, the second direction and the third direction are mutually perpendicular. In order to solve the problem that the stirrup 100 in the prior art does not slide smoothly on the longitudinal bars 200, in the present application, the size of the stirrup 100 in one direction needs to be increased (that is, the distance h between the stirrup 100 and the transverse rib 202 of each longitudinal bar 200 in the two rows of longitudinal bars located at the outermost side and arranged oppositely is greater than the standard distance h'), the relative position of the longitudinal bar 200 and the stirrup 100 is set by using the characteristics of the transverse rib 202 and the longitudinal rib 201 distributed on the steel bar, so that the stirrup 100 can be smoothly pushed to the pre-installation position, and then the stirrup 100 is deflected by an angle (deflection angle α), so that the stirrup 100 abuts against the two rows of longitudinal bars located at the outermost side and the two rows of longitudinal bars 100 located at the outermost side in the plurality of longitudinal bars 200 are welded or bound and fixed on the plurality of longitudinal bars 200, which is favorable for the automatic production of the steel reinforcement cage in a factory.
It should be noted that the standard distance h' in this application refers to the distance between the stirrup 100 and the transverse rib 202 of each longitudinal bar 200 in the two opposite rows located at the outermost side in the manufacturing process of the reinforcement cage in the prior art. The distance h' is a variable value, and varies with the selected specifications of the longitudinal bars 200 and the stirrups 100 in the reinforcement cage. The standard deflection angle α 'in the present application refers to a deflection angle α' when the distance between the stirrup 100 and the transverse rib 202 of each longitudinal bar 200 in two rows of the outermost opposite longitudinal bars is the standard distance h 'in the manufacturing process of the reinforcement cage in the prior art, and the corresponding stirrup 100 abuts against the transverse rib 202 of the longitudinal bar 200, where α' is less than 2 degrees.

the push down lever 400 is further moved in the first direction away from the stirrup 100 by a distance b (step S15);
then, limiting the limit position of the stirrup 100 sliding along the first direction by the limiting structure 300 (step S20);
then, the upper push rod 400 is used to continuously push the stirrup 100 to move for a distance b in the first direction, so that the stirrup 100 rotates around a contact area formed between the stirrup 100 and the limiting structure 300, and the stirrup 100 is pushed to a pre-locking position (step S30);
welding the joints of the first stirrup 100 and the plurality of longitudinal bars 200 in the first direction (step S40);
thereafter, the plurality of longitudinal bars 200 and the first stirrup 100 are retracted in the first direction by a distance b by using the bar stretching mechanism (step S50);
then, welding the abutting positions of the first stirrup 100 and the two uppermost longitudinal bar rows (step S60);
thereafter, the plurality of longitudinal beads 200 and the first stirrup 100 are advanced in the first direction by a distance 2b using the lacing mechanism (step S70);
then, welding the abutting positions of the first stirrup 100 and the two longitudinal bar rows positioned at the lowest part (step S80);
after step S80, the plurality of longitudinal bars 200 and the first stirrup 100 are further advanced in the first direction by a distance c (step S90); at this time, the welding process of the first stirrup 100 and the plurality of longitudinal bars 200 can be completed.
Then, the welding process of the second stirrup 100 to the nth stirrup 100 is sequentially completed according to the steps S10 to S80, where N is an integer greater than 1.
It should be noted that, after the last stirrup 100 to be welded in position is welded, the reinforcement cage is manufactured. The distance c is a distance between two adjacent stirrups 100 in the reinforcement cage in the first direction. The forward distance 2b in this application refers to a distance 2b in the feeding direction of the longitudinal rib 200 in fig. 1, and the backward distance b in this application refers to a distance b in the direction opposite to the feeding direction of the longitudinal rib 200 in fig. 1.
From the above description, it can be seen that the dimension H in the height direction of the stirrup is larger than the height dimension of the stirrup of the standard component of the same specification, that is, the deflection angle α is greater than or equal to 2 °, so that the stirrup can smoothly slide on the longitudinal bar, and the stirrup can be conveniently slid to the pre-installation position. In addition, through the mode that the stirrup deflects for indulging the muscle for the stirrup can follow preinstallation position and switch over to locking position in advance, avoided like this because of the stirrup with lie in the outside relative two lines set up indulge the distance h between the transverse rib of each muscle of indulging in the muscle row too big and lead to the stirrup can not accurate welding position on indulging the muscle problem, thereby ensure that the stirrup can accurate welding position on indulging the muscle, and then improved the preparation qualification rate of steel reinforcement cage.
