Germany developed a method of strengthening reinforced concrete structures with steel plates, which adopts the double component epoxy resin adhesive steel plate or other steel piece pasted on the surface of concrete, constitute a concrete - steel composite adhesive three-phase system * by reinforced concrete member after pasting steel plate, can partly replace the reinforced by steel plate the role of * therefore, when the bearing capacity of reinforced concrete members due to insufficient or deformation, cracks affect the structure of normal use, can use adhesive paste to steel reinforced concrete members outside the appropriate location, to meet the bearing of #.
