Abstract
Description
Technical Field
[0001] The utility model relates to a steel bar anchoring device for concrete construction, belonging to the field of construction. Background Art
[0002] The steel bars in reinforced concrete structures can bear stress mainly due to the bonding and anchoring effect between the steel bars and concrete. Therefore, the anchoring of the steel bars is the basis for the stress of the concrete structure. If the anchoring fails, the structure will lose its bearing capacity and thus cause structural damage.
[0003] The existing steel bar anchoring device is a circular anchor with an internal thread. The steel bar is processed with an external thread to match it, so that the steel bar and the circular anchor are threadedly connected. In this connection method, the steel bar must be processed in advance to prefabricate the external thread head, which increases the steel bar prefabrication process and processing costs. Once the external thread head is damaged, it cannot be connected and installed, making production and management work cumbersome. Utility Model Content
