[0002] Currently, safety accidents often occur during the running of the hanging basket during construction. During running, the entire load force of the hanging basket is completely borne by the rail, so the anchoring of the hanging basket rail is particularly important to ensure safety.

[0003] Since welding of fine-rolled ribbed steel is currently not possible, the iron wire tying technique used in China primarily involves attaching the fine-rolled ribbed steel to the reinforcing steel for anchoring the suspended cage. To ensure safety, the anchorage depth of the fine-rolled ribbed steel in the concrete must not be too shallow. The fine-rolled ribbed steel is usually installed only after the reinforcing steel has been tying and the formwork has been securely and reinforced. Therefore, the iron wire tying technique proves to be cumbersome for securing the fine-rolled ribbed steel, resulting in slow construction progress. Content of the invention

The box girder is then filled with concrete. Once the concrete begins to set, the limiting nut is loosened and the support beam is carefully withdrawn. The positioning and pre-embedding of the fine-rolled ribbed steel is complete.This auxiliary device for positioning fine-rolled ribbed steel on a hanging basket rail ensures the distance between the pre-embedded fine-rolled ribbed steels due to the installation of several positioning sleeves at equal intervals along the longitudinal direction on the support beam; and due to the vertical axis of the positioning sleeve during use, the vertical position of the pre-embedded fine-rolled ribbed steel is ensured; at the same time, due to the adjustable position of the threaded fit between the limit nut and the upper end portion of the fine-rolled ribbed steel, the height of the pre-embedded fine-rolled ribbed steel can be controlled, thus facilitating the positioning of the fine-rolled ribbed steel.
