However, the anchoring point is single, and the technical problems of stress concentration and local weak areas are easy to occur.
Disclosure of Invention
The to-be-solved technical problem of the utility model is how to provide a simple structure, dismantle the convenience, and can effectively reduce stress concentration's mechanical anchoring device.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the design is a mechanical anchoring device, which comprises a sleeve matched with an external thread structure of an anchoring part to be anchored, wherein external threads are arranged at two ends of the sleeve, and an end full anchoring plate and an extended full anchoring plate matched with the thread structure of the sleeve are respectively arranged at two ends of the sleeve.
Preferably, the head full-anchoring plate comprises a part of anchoring piece and a head anchoring piece arranged on the periphery of the part of anchoring piece.
Preferably, the expansion full-anchoring plate comprises a partial anchor and an expansion anchor arranged on the periphery of the partial anchor.
Further, one of the partial anchors is connected with the head anchor through a thread structure, and the other partial anchor is connected with the expansion anchor through a thread structure.
Furthermore, the sleeve, part of the anchoring pieces, the end anchoring pieces and the expansion anchoring pieces are all made of high-strength steel.
Preferably, the major diameter of the peripheral thread of the sleeve is 25-35 mm.
Furthermore, the thickness of the partial anchoring part is 15-30 mm, and the outer diameter of the thread is 40-55 mm.
Further, the end anchoring piece comprises a substrate with the thickness of 0-10 mm; the thickness of the end anchoring piece is 20-40 mm, and the outer diameter is 60-70 mm.
Furthermore, the thickness of the expansion anchoring part is 20-40 mm, and the outer diameter is 60-70 mm.
Compared with the prior art, the utility model has the beneficial technical effects of:
1. the utility model discloses a set up anchor assembly's mode respectively at sleeve both ends, increased stress point, effectively reduced the appearance of stress concentration phenomenon, ensured the reliability of anchor, promoted the security of reinforcing bar anchor greatly.
2. The utility model discloses it is convenient to dismantle with the structural connection of screw thread to prefer each part.
