CONSTRUCTION METHOD OF WOODEN RIGID FRAME STRUCTURE
To provide a construction method of a wooden rigid frame structure accomplishing a rigid connection of a column beam framework as a connection structure, solving a looseness of the connection part or facilitating a repair of the deformation even when the framework is deflected later by an earthquake or the like, or is subject to a secular change.SOLUTION: A metallic screw-type connection mechanism 2 aiming for a rigid connection of a column beam comprises a first coupler 4, a joint bolt 5, a bearing nut 6 and a second coupler 7. Inner screws 7A,7B of the second coupler are in a helical shape in a same direction, and a screw pitch pB of the second inner screw 7B engaged with a head outer peripheral screw 20A projecting from a step surface 22a is arranged to be larger than the screw pitch pA of the first inner screw 7A positioned at the joint bolt 5 side. A lag screw 14 of a beam to be installed next 11B is pulled in a direction of an existing column 12A by a rotation of the second coupler 7, thus, the beam to be installed next 11B can be joined to the existing column 12A rigidly.SELECTED DRAWING: Figure 1
【課題】接合構造として柱梁軸組の剛接合を達成し、地震などにより事後的に軸組が歪んでも、また経年変化するなどしても、接合部の緩みを解消したり、変形の修復を容易にする木造ラーメン構造体の構築方法を提供する。【解決手段】柱梁の剛接合を図る金属製ねじ式接合機構２が、第一カプラー４、連結ボルト５、支圧用のナット６、第二カプラー７を備える。第二カプラーの内ねじ７Ａ，７Ｂは同一方向の螺旋をなすが、段差面２２ａから突出するヘッド外周ねじ２０Ａとかみ合わされる第二内ねじ７ＢのねじピッチｐBは、連結ボルト５の側に位置する第一内ねじ７ＡのねじピッチｐAより大きくされている。第二カプラー７の回転でもって次設梁１１Ｂのラグスクリュー１４を既設柱１２Ａの方向に引き寄せ、結果として次設梁１１Ｂを既設柱１２Ａに剛強に接合することができる。【選択図】図１
