An anchor cap comprises an oval body with an internal cavity in the form of an oval displaced offset relative to the longitudinal axis of symmetry of the body. A half of the lower surface of the inner cavity is made with a slope upwards at an angle of 6-9° in the opposite direction relative to the displacement of the inner cavity, and from the opposite side form the slope on the upper surface of body a horizontal board is made, wherein on the lower bearing surface of the body from the opposite side from the horizontal board a ledge of spherical shape is made, and on the edge of upper surface of cavity crushable elements are made. |
