HOT-MELT ANCHOR HEAD

The invention relates to a hot-melt anchor head and belongs to the technical field of fixed-foundation buildings. The hot-melt anchor head includes an anchor ring (1) provided with a through hole, a guide wire (2), an electrical hot-melt member (3) arranged on the anchor ring (1), a clamp piece (5) arranged in the through hole to clamp an anchor cable reinforcement (4), and a strain gauge (7) connected to the guide wire (2) and arranged on the surface of the anchor ring (1), wherein the bottom of the anchor ring (1) is provided with a bearing plate (6); the bearing plate (6) is provided with an opening opposite to the through hole, and the anchor ring (1) is made of a metal material; and a surface of the anchor ring (1) is formed with a coating layer (8) by injection moulding with a hot-melt material, the strain gauge (7) is coated by the coating layer (8) and is in close contact with the surface of the anchor ring (1) so as to be integrally formed, an end, close to the bearing plate (6), of the anchor ring (1) extends inwards and is provided with a flange, and the flange is used for holding a part, located inside the through hole, of the coating layer (8). According to the hot-melt anchor head, a complete protective layer is integrally formed by injection moulding on the surface of the metal anchor ring (1), so that the structure is simple, force measurement is accurate, and corrosion prevention of the whole anchor head, filling limitations required when clamping is conducted in the through hole of the anchor head and filling hot-melting required when releasing is conducted in the through hole of the anchor head are achieved at the same time.
