A multidirectional corrugate grid structure module according to the present invention includes: a first protruding corrugate stack module including a first base plane and a plurality of first protruding parts protruding from the first base plane in a concavo-convex structure to have a shape of a tapered polyprism; and a second protruding corrugate stack module including a second base plane and a plurality of second protruding parts protruding from the second base plane in a concavo-convex structure to have a shape corresponding to the shape of the first protruding parts. When the first layer protruding corrugate stack module and the second layer protruding corrugate stack module are stacked, an upper surface of the first protruding part is bonded to the second base plane, an upper surface of the second protruding part is bonded to the first base plane, and a part of side surfaces of the first protruding part is bonded to a part of side surfaces of the second protruding part corresponding thereto, so that a flange defined by the base planes and the upper surfaces of the protruding parts and a web defined by the side surfaces of the protruding parts in the stack-coupled stack modules are configured to have sections having continuity in a plurality of directions. According to the multidirectional corrugate grid structure module and a sandwich structure module having a multidirectional corrugate core including the same of the present invention, when stacking the protruding corrugate stack modules, a cross section defined by the bonding part and each stacked stack module has continuity in various directions in a zigzag shape so that high bending stiffness, shear stiffness, twist stiffness, etc. can be provided in these directions, therefore, a stability of the structure module of the present invention is improved, thereby effectively preventing damage and breakage. |
