DIFFERENT DIAMETER COLUMN-BEAM JOINT STRUCTURE
To provide different diameter column-beam joint structure that can reduce a welding amount as much as possible while securing sufficient stress transmission between a column and a beam in the different diameter column-beam joint structure in which a large-thickness panel core and a diaphragm are welded and joined.SOLUTION: In a different diameter column-beam joint structure 80A, a lower floor column 40 is weld and joined at bottom edges 13 of a panel core 10, a through-diaphragm 20A is weld and joined at top edges 12 of the panel core 10, and an upper floor column 50 with small cross-sectional dimension than the lower floor column 40 is weld and joined at an upper surface 21 of the through-diaphragm 20A. The top edge 12 of a panel plate 11 has a flat surface 15 up to an intermediate position and a single-bevel groove 16 from the intermediate position throughout the outside. A backing strip 30 is sandwiched between the flat surface 15 and the lower surface 22 of through-diaphragm 20A, and a plate thickness t8 of the backing strip 30 forms a root gap. A butt welding part 70 is provided at the space G2 formed with the single-bevel groove 16, the root gap, and the lower surface 22 of through-diaphragm 20A.SELECTED DRAWING: Figure 3
【課題】板厚の厚いパネルコアとダイアフラムが溶接接合される異径柱梁接合構造において、柱梁間の十分な応力伝達を確保しながら、可及的に溶接量を少なくできる異径柱梁接合構造を提供すること。【解決手段】パネルコア１０の下端１３に下階柱４０が溶接接合され、パネルコア１０の上端１２に通しダイアフラム２０Ａが溶接接合され、通しダイアフラム２０Ａの上面２１に下階柱４０よりも断面寸法の小さな上階柱５０が溶接接合されている、異径柱梁接合構造８０Ａであり、パネル板１１の上端１２には、途中位置までが平坦面１５で、途中位置から外側に亘ってレ型開先１６があり、平坦面１５と通しダイアフラム２０Ａの下面２２の間に裏当て金３０が挟まれ、裏当て金３０の板厚ｔ８がルートギャップを形成し、レ型開先１６とルートギャップと通しダイアフラム２０Ａの下面２２とにより形成される空間Ｇ２に突合せ溶接部７０が設けられている。【選択図】図３
