This embodiment provides a supplementary tool of steel reinforcement cage for supplementary steel reinforcement cage's preparation.

Referring to fig. 1, a reinforcement cage 10 includes a plurality of hoop reinforcements 11 arranged in a ring shape at intervals, and an upper longitudinal reinforcement 12 and a lower longitudinal reinforcement 13 inserted in sequence into each hoop reinforcement 11 and arranged in parallel up and down. It will be understood by those skilled in the art that there are a plurality of upper longitudinal ribs 12 and a plurality of lower longitudinal ribs 13, which are correspondingly disposed. For convenience of description, only one upper longitudinal rib 12 and one lower longitudinal rib 13 will be described, and the extending direction of the upper longitudinal rib 12 and the lower longitudinal rib 13 will be defined as the front-rear direction, and the stirrup 11 will be placed upright with its length direction being the left-right direction and its width direction being the up-down direction.

Referring to fig. 2 to 5, the reinforcement cage auxiliary fixture includes a clamping structure 20, a first limiting structure 30 and a second limiting structure 40 for temporarily fixing the stirrup 11, the upper longitudinal bar 12 and the lower longitudinal bar 13, respectively.

The plurality of holding structures 20 are used for holding the left and right sides of each stirrup 11 and making each stirrup 11 stand.

The first stopper structure 30 is plural and is used for supporting the lower longitudinal rib 13 and restricting the movement of the lower longitudinal rib 13 in the horizontal direction.

The number of the second limiting structures 40 is multiple, each second limiting structure 40 comprises a fixed part 41 and a cantilever arm 42 rotatably connected with the fixed part 41, each cantilever arm 42 can rotate relative to the fixed part 41 and can be switched between a supporting position and a avoiding position, each cantilever arm 42 can jointly support the upper longitudinal rib 12 when located at the supporting position, and each cantilever arm 42 is pushed to the avoiding position by the lower longitudinal rib 13 when the lower longitudinal rib 13 moves upwards.

Correspondingly, the automatic bundling method of the reinforcement cage 10 comprises the following steps:

placing a plurality of stirrups 11 on each clamping structure 20 respectively, and clamping the stirrups by each clamping structure 20 in an upright state;

sequentially passing the lower longitudinal bars 13 through the stirrups 11 and placing the lower longitudinal bars on the first limiting structures 30;

The supplementary tool of steel reinforcement cage that this embodiment provided to stirrup 11's temporary fixation, the mode that adopts the both sides centre gripping goes on to in order to ensure that stirrup 11 is the state of erectting, and avoid becoming the obstacle of indulging muscle 12 or indulging muscle 13 and alternate down. The temporary fixation of the lower longitudinal bead 13 may be performed by using a general support structure and restricting the movement of the lower longitudinal bead 13 in the left-right direction. The lower longitudinal rib 13 is an elongated member and is not easily moved in the front-rear direction by its own weight, and therefore, it is not necessary to limit the movement in the front-rear direction. For the temporary fixation of the upper longitudinal bar 12, since the upper longitudinal bar 12 is located right above the lower longitudinal bar 13, the second limiting structure 40 is rotatably connected with the cantilever 42 through the fixing member 41, so that the fixing member 41 can avoid the position of the first limiting structure 30, and the free end of the cantilever 42 can reach the upper side of the first limiting structure 30 to support the upper longitudinal bar 12. Due to the rotary connection of the cantilever 42 and the fixing piece 41, the upper longitudinal bar 12 is placed on each cantilever 42, and after each stirrup 11, the upper longitudinal bar 12 and the lower longitudinal bar 13 are bound to form the reinforcement cage 10, in the process of moving the reinforcement cage 10 out of the jig, the lower longitudinal bar 13 moves upwards to push the cantilever 42 to rotate from the supporting position to the avoiding position, so that the reinforcement cage 10 can be smoothly and quickly moved away from the jig, and the manufacturing efficiency of the reinforcement cage 10 is improved.

It should be noted that, since the lower longitudinal rib 13 is inserted into each stirrup 11 from one side (front side or rear side) and is placed on the first limiting structure 30, a large clearance space exists between the cantilever 42 and the first limiting structure 30, and the insertion operation of the lower longitudinal rib 13 is not hindered. When the reinforcement cage 10 moves upward after being manufactured, the lower longitudinal rib 13 abuts against the cantilever 42 to further push the cantilever 42 to rotate, so that the lower longitudinal rib 13 smoothly leaves a gap space between the cantilever 42 and the first limiting structure 30. In other words, in the present embodiment, the rotation between the cantilever 42 and the fixing member 41 is generated by the upward movement of the lower longitudinal rib 13, and a controller for controlling the rotation of the cantilever 42 is not required.
