Description

Technical Field

[0001] This utility model relates to the field of concrete formwork technology, and more specifically, to a crack-resistant concrete formwork. Background Technology

[0002] Concrete formwork refers to the formwork used for shaping freshly poured concrete and the entire structural system supporting the formwork. Formwork can be classified in various ways, including by shape (flat and curved) and by load-bearing capacity (load-bearing and non-load-bearing). Before the concrete wall panel fully hardens, concrete formwork is needed to support the wall and provide good protection. However, existing concrete formwork is simply locked using threaded sleeves that mate with internal pipe threads. This threaded connection is prone to loosening, lacking a suitable reinforcing locking mechanism. Furthermore, the device is prone to lateral deviation during use, affecting production quality, and lacks suitable support and protection mechanisms. Additionally, the installation of the reinforcing locking mechanism is cumbersome, and a suitable quick-installation mechanism is lacking. Utility Model Content
