A metallic roof materialaccording to the present invention comprises: a front substratemade of a metal sheet, the front substratecomprising a body portionformed into a box shape; a back substratearranged on a back side of the front substrateso as to cover an opening of the body portionand a core materialfilled between the body portionand the back substratethe metallic roof materialbeing tightened to a roof base by driving at least one tightening member into the body portionwherein a top plate portionof the body portioncomprises at least one protruding ribcomprised of at least one protrusiondisposed along a side of a polygon or along a circle, and wherein the metallic roof materialis configured such that the tightening member is driven into an inner regionof the protruding rib

Metallic roof material and roofing method using same

The present invention relates to a metal roofing materialthat is arranged on an eave-side metal roofing material in an eave-ridge directionof a roof so as to overlap the metal roofing material and the eave-side metal roofing material. The metal roofing material includes a front substratemade of a metal sheet and including a body portionformed in a box shape; a back substratearranged on the back side of the front substrateso as to cover an opening of the body portion; a core materialfilled between the body portionand the back substrate; and at least one plate reinforcing memberthat is embedded in the core materialat a position closer to the back substratethan a top plate of the body portionor that is disposed in contact with the outer surface of the back substrate

Metal roofing material and roofing method

A body portionof a front substrateincludes first side surfacesand second side surfaces, each of the second side surfacesbeing arranged at a position protruding toward the outer side along a width directionthan the first side surfaceEach of the first side surfacesincludes a side flangeA protruding width of the side flangefrom the first side surfaceis equal to or less than a protruding width of the second side surfacefrom the first side surfaceA metal roofing memberis arranged on a roof base while abutting at least the second side surfaceagainst a second side surface of other metal roofing member.

Metal roofing material, and roofing structure and roofing method using same

A metal roofing material according to the present invention comprises: a front substratehaving a body portion, the body portionbeing comprised of a metal sheet and being formed into a box shape; a back substrate disposed on a back side of the front substrateso as to cover an opening of the body portion; a core material filled between the body portionand the back substrate, the metal roofing material being arranged side by side on a roof base together with other metal roofing materials, wherein at least one edge indicatorin the form of protrusion is provided at an edge portion of a top plateof the body portion

Metal roofing material

A metal roofing memberis disposed side by side with another metal roofing member on a roof base. The metal roofing memberhas a box-shaped front substratemade of a metal sheet, a rear substratedisposed on the rear side of the front substrate, so as to cover an opening of the front substrate, and a core materialmade from a foam resin and filled in between the front substrateand the rear substrate. The front substrateresults from forming the metal sheet into a box shape. The front substratehas a side wall portion that is continuous in the circumferential direction and is formed by performing drawing or bulging processing on the metal sheet. The front substratehas a height of 4 mm to 8 mm.

Metal roofing member, production method thereof, roofing structure and roofing method

A metal roofing memberhas a front substrate, a rear substrateand a core material. The front substrateis made of a metal sheet. In the front substrate, a box-shaped body portionand a flange portionextending from the body portionare provided. The flange portionis formed by folding back, over the rear side of the front substrate, of a metal sheetextending outwards of the body portionin a directionperpendicular to a height directionof the body portion, from a lower edge of the body portion, in such a manner that the metal sheetwraps around the rear substrate. The metal roofing memberis disposed on a roof base, with the flange portionbutting against a flange portionof another metal roofing member.
