“The Life Story of the 'Christmas Tree Anchor” In the industrial field,it is a sophisticated and powerful anchoring system.Its name stems from its unique deployment form: after installation, multiple anchor pins or wings inside the anchor bolt will spread out like the branches of a Christmas tree,forming a huge,multi-point mechanical lock,thereby achieving extremely high tensile and shear force-bearing capacity in concrete or rock substrates. "The core technology of the'Christmas Tree Anchor' lies in its'post-installed' installation and 'post-expansion' mechanical model.Unlike traditional anchor bolts that require pre-burial,it can be installed by drilling holes on the completed concrete structure,significantly enhancing the flexibility and efficiency of const...
Core product features The spring clip design firmly establishes the foundation of safe fastening. As a specialized fastener developed for "hollow substrate suspension fastening", the core advantage of Hebei Duojia Metal's Orchid Clip (Spring Toggle Fixing) lies in its innovative "spring-type expandable clip" structure, combined with precise technical design, to ensure suspension stability.The product consists of a screw, spring clip,washer, and nut.During installation,the spring clip can be compressed and pass through the reserved hole in the substrate, and after entering the hollow layer, it automatically expands to form "reverse support".After tightening the nut,the external component can be firmly fixed on the hollow wall,ceiling, and other substrate surface...
