Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a reinforcing steel bar bundling and positioning device. BACKGROUND

[0002] A reinforcing cage is a pre-fabricated steel structure for cast-in-situ piles, hole piles, columns, etc., and mainly plays a role in resisting tension. The reinforcing cage restrains the pile concrete to bear certain axial tension. Since the cast-in-situ piles, hole piles, columns, etc. are usually large, the reinforcing cage is usually fabricated at the construction site.

[0003] When the reinforcing cage is fabricated at the construction site, the positions of the main reinforcement are first vertically positioned, and the main reinforcement usually has at least four main reinforcement. Then, the positions of the stirrups to be bundled on the main reinforcement are marked, and the stirrups are then wound and bundled on the main reinforcement according to the marks. All the main reinforcement is bundled together, and finally the main reinforcement and the stirrups form a reinforcing cage. During the fabrication of the reinforcing cage, the main reinforcement needs to be positioned to avoid displacement and tilting of the main reinforcement during the bundling process, which affects the forming effect of the final bundled reinforcing cage.

[0004] In the prior art, a single auxiliary positioning device or a frame-type auxiliary positioning device is usually used to position the main reinforcement. When a single auxiliary positioning device is used, each main reinforcement is usually positioned and supported separately. However, the single auxiliary positioning devices are not limited to each other and cannot limit the relative distance between the main reinforcements. When the single auxiliary positioning device deviates during the bundling process of the reinforcing cage, the main reinforcement also deviates, causing misalignment between the main reinforcements and affecting the forming effect of the reinforcing cage. Although the frame-type auxiliary positioning device can simultaneously fix multiple main reinforcements and limit the relative distance between the main reinforcements, it can only fix the main reinforcements located at the edges of the frame, is limited by the size of the frame, and cannot adapt to main reinforcements of reinforcing cages with different row and column spacings. Moreover, it occupies a large area and is inconvenient to use. SUMMARY

The working process of the embodiment is as follows:

[0046] The four steel bars 23 are vertically inserted into the ground, and the support mechanisms 34 connected with the four positioning plate assemblies respectively support one steel bar 23, so that all the four steel bars 23 are supported, then the connecting plate 3 in the connecting groove 4 of the first positioning plate assembly 1 is pulled out, and the elastic clamping blocks 5 at both ends of the connecting plate 3 are clamped in the groove holes of the connecting groove 4 of the first positioning plate assembly 1 and the connecting groove 4 of the second positioning plate assembly 2 respectively, so that the distance between the first positioning plate assembly 1 and the second positioning plate assembly 2 is limited in the length direction, and the third positioning plate assembly 37 and the fourth positioning plate assembly 38 are connected in the same way, and the distance between the third positioning plate assembly 37 and the fourth positioning plate assembly 38 is limited in the length direction.
