Description

Technical Field

[0001] The utility model relates to the field of steel bar binding, in particular to a variable-section assembled steel bar binding cradle. Background Art

[0002] Traditionally, rebar cage tying has been done manually on-site, with quality significantly impacted by the site environment and human factors. Furthermore, this method suffers from low efficiency, uneven rebar spacing, insufficient rebar cover thickness, and poor overall cage stability. This results in a range of quality indicators failing to meet design and regulatory requirements, resulting in a low pass rate for finished products and significant waste of resources.

[0003] Currently, the tying of rebar cages is mostly done using a tying system. This system firstly ensures the qualified rate of the rebar cover, secondly ensures the accurate arrangement and uniform spacing of the horizontal rebar, and finally, it greatly speeds up the rebar tying process, ensuring construction efficiency. However, most complex projects often require the tying of rebar cages of varying specifications and cross-sectional dimensions, and most tying systems have poor applicability. This necessitates the production of a large number of additional tying systems. On the one hand, most tying systems cannot be recycled, resulting in a significant waste of resources. On the other hand, the stacking of tying systems of different specifications also takes up a lot of space, resulting in a cluttered and disorderly construction site.

[0004] Therefore, in view of the problems that the above-mentioned ordinary tire frames cannot be used for binding steel cages with different cross-sectional sizes and the stacking of tire frames of different specifications takes up a lot of space, there is an urgent need for an assembled tire frame that can be used for binding steel cages with different cross-sectional sizes to improve the use scenarios of the tire frame.
