JOINING STRUCTURE OF SHAPED MEMBERS AND ROOF STRUCTURE

To provide: a joining structure of a shaped members which can join the shaped members to each other at an arbitrary position while flattening a joining face; and a roof structure.SOLUTION: In a joining structure 10 of shaped members which joins a columnar support and a beam 4, a joining face part 41 which can be applied with drilling processing is formed at the beam 4, and an outer face of the joining face part 41 is configured to be a flat joining face 411. A back plate 7 abutting on an upper face 412 of the joining face part 41 is arranged in the beam 4 so as to be slidable in its longitudinal direction. Fixing holes 7A respectively screwed with fixing bolts 6 are formed in the back plate 7. The fixing bolt 6 penetrates a penetration hole 41a of the joining face part 41 from a connecting metal fixture 36 of the columnar support, and is screwed into the fixing hole 7A of the back plate 7. Burr avoidance parts 45 separated from the back plate 7 are formed at portions corresponding to the fixing holes 7A out of the joining face part 41 along the longitudinal direction of the beam 4.SELECTED DRAWING: Figure 4 【課題】接合面をフラット化しつつ形材同士を任意の位置で接合できる形材の接合構造および屋根構造体を提供すること。【解決手段】形材の接合構造１０は、支柱および梁４を接合する接合構造であって、梁４には、孔開け加工可能な接合面部４１が形成され、接合面部４１の外面はフラットな接合面４１１とされる。梁４の内部には、その長手方向にスライド可能に接合面部４１の上面４１２に当接する裏板７が配置される。裏板７には、固定ボルト６が螺合する固定孔７Ａが形成される。固定ボルト６は、支柱の連結金具３６から接合面部４１の貫通孔４１Ａを貫通して裏板７の固定孔７Ａに螺合する。接合面部４１のうち固定孔７Ａに対応する部分には、裏板７から離間したバリ避け部４５が梁４の長手方向に沿って形成される。【選択図】図４
