Cross-ribbed anchor plate resistant to breakage deformation

Abstract

This utility model discloses a cross-ribbed anchor bolt support plate resistant to fracture deformation, relating to the technical field of geotechnical engineering support equipment. It includes a support plate body with a protruding portion and a square flat plate portion. The protruding portion has a cross-shaped rib structure, and the square flat plate portion has a diagonal rib structure, with the two rib structures arranged crosswise. A central hole for anchor bolts to pass through is opened in the center of the support plate body. The height of the cross-shaped rib structure is 1 / 3 to 2 / 3 of the height of the protruding portion. The support plate body is made of high-strength alloy steel with a yield strength of not less than 500 MPa. This utility model enhances the structural strength of the support plate through the cross-arranged rib structure, disperses stress concentration, and effectively solves the problem of existing support plates being prone to compressive fracture deformation. While controlling weight and cost, it improves the stability and reliability of anchor bolt support, and is suitable for support scenarios such as mines, tunnels, and slopes.
