The invention discloses a concave-convex point type broadside collision prevention and freezing prevention compound structure. A second buffer pad layer, a concave-convex collision prevention plate and a first buffer pad layer are sequentially arranged in the direction from an inner ship broadside plate to an outer ship broadside plate. The hollow protruding portion and the hollow concave portion of the concave-convex collision prevention plate, the gap between the concave-convex collision prevention plate and each buffer pad layer and the gap between the concave-convex collision prevention plate and the outer ship broadside plate are filled with freezing prevention materials. The concave-convex point type broadside collision prevention and freezing prevention compound structure can sufficiently absorb energy in all the directions, and the space utilization rate is greatly improved; the structure is simple, construction is convenient and rapid, and ships in an ice zone are protected within a short period; and through sufficient utilization of the excellent characteristics of the various compound materials, the dual effects of preventing collision and freezing of the broadside structure are achieved, and the problems of collision and freezing are solved easily and conveniently.
