Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a pre-buried steel bar connector. Background Art

[0002] During construction, embedded rebar combines concrete with steel to form a reinforced concrete composite, enhancing the structure's compressive and tensile strength. Currently, the most common method for installing embedded rebar is to tie it directly to the main reinforcement skeleton, using lead wire (binding wire) to securely secure the embedded rebar to the main reinforcement skeleton. Binding connections have relatively low strength when subjected to tension and shear forces, making them prone to loosening or breaking when subjected to heavy or dynamic loads. Therefore, a connector has been designed that increases the connection point with the main reinforcement skeleton, thereby enhancing the embedded rebar's ability to withstand heavy or dynamic loads. Utility Model Content

[0007] A protective tube is provided between the two bottom plates. The protective tube is concentric with the through hole and is located outside all the arc-shaped elastic plates. The connecting rib is located outside the protective tube.

[0008] A grouting hole communicating with the interior of the protective tube is opened on any of the bottom plates.

[0009] Furthermore, a plurality of arc-shaped elastic plates are fixedly provided on the other bottom plate along the edge of the through hole, one end of the arc-shaped elastic plate is fixed on the bottom plate, and the other end is close to the other bottom plate and the close end is located outside the through hole.
