STEEL INTERIOR-EXTERIOR BASE MATERIAL AND MANUFACTURING METHOD THEREOF
To provide a steel interior-exterior base material by which a steel base member is firmly fastened to other members and plastic deformation of steel base member is prevented.SOLUTION: A steel interior-exterior base material 100 includes: a first joint plate 30 and a second joint plate 40, which are fixed to a first furring strip 1; a second furring strip 2 having a closed cross-section S1, which is connected to the first furring strip 1 via the first joint plate 30 and the second joint plate 40; and a stepped bolt 20 that penetrates closed cross-section S1 of the second furring strip 2, the first joint plate 30 and the second joint plate 40. The stepped bolt 20 has a cylindrical portion 21 and a screw portion 22 where the thread is formed, in which the outer diameter R1 of the cylindrical portion 21 is larger than the outer diameter R2 of the screw portion 22. The diameter D1 of the insertion side bolt hole 31 of the first joint plate 30 is larger than the outer diameter R1 of the cylindrical portion 21. The diameter D2 of the fastening side bolt hole 41 of the second joint plate 40 is smaller than the outer diameter R1 of the cylindrical portion 21 and larger than the outer diameter R2 of the screw portion 22.SELECTED DRAWING: Figure 3
【課題】鋼製下地部材が他の部材に堅固に締結されるとともに、鋼製下地部材の塑性変形が防止される鋼製内外装下地材を提供する。【解決手段】鋼製内外装下地材１００は、第一胴縁１に固定される第一接合板３０及び第二接合板４０と、閉鎖断面Ｓ１を有するとともに、第一接合板３０及び第二接合板４０を介して第一胴縁１に接続される第二胴縁２と、第二胴縁２の閉鎖断面Ｓ１、第一接合板３０及び第二接合板４０を貫通する段付ボルト２０とを備え、段付ボルト２０は、円筒部２１と、ネジ山が形成されるネジ部２２とを有し、円筒部２１の外径Ｒ１はネジ部２２の外径Ｒ２よりも大きい。また、第一接合板３０の挿入側ボルト孔３１の径Ｄ１は円筒部２１の外径Ｒ１より大きい。第二接合板４０の締結側ボルト孔４１の径Ｄ２は円筒部２１の外径Ｒ１より小さく、ネジ部２２の外径Ｒ２よりも大きい。【選択図】図３
