<p>The present invention relates to a channel anchoring device for construction industry, which comprises a channel rail with a hollow interior and T-type bolts, anchor shafts or steel base plates attached onto the exterior surface of the web of the channel, the channel anchoring device with anchor shafts is suitable to be embedded into the concrete structure, while the channel anchoring device with steel base plates is suitable to be welded onto the steel structure, the T-bolts are inserted into the gap between the return legs of two flanges of the channel. The said channel rail with a hollow interior is an anchoring channel, preferably manufactured from hot-rolled steel or stainless steel material by the process of hot rolling. The head of T-bolt is locked within the return legs of two flanges of the anchor channel. On the inner surface of the return legs of two flanges of the anchor channel, serrations are arranged respectively. On the lower surface of the head of T-bolt, serrations are also arranged; the serrations of T-bolt head connect with the serrations on the return legs of two flanges of the anchor channel in an engaged lock. The present invention prevents the shift of T-bolt along the channel, moreover no interference to reinforcement concrete installation.</p> |
