METHOD FOR REINFORCING WOODEN BUILDING MEMBER

ADACHI HIROYUKI

PROBLEM TO BE SOLVED: To reinforce a through hole of a wooden building member.SOLUTION: Reinforcing hardware 550 which reinforces a through hole TH1 formed from one face to the other face of a beam BM as a wooden building member comprises: a first plate member 560 made of a metal plate in a rectangular shape in plan view; a cylinder member 570 made of a metal cylinder; and a second plate member 580 made of a metal plate in a rectangular shape in plan view. The first plate member 560 is arranged on the one face (lower face) of the beam BM, and has a through hole 560A formed to allow a bolt member 220 as a rod-like fastener to penetrate. The cylinder member 570 is inserted and fitted in the through hole TH1 of the beam BM to the overall length thereof, and the bolt member 220 can penetrate. The second plate member 580 is arranged on the other face (upper face) of the beam BM, and has a through hole 580A formed to allow the bolt member 220 to penetrate.SELECTED DRAWING: Figure 13

【課題】木製建築部材の貫通孔を補強する。【解決手段】木製建築部材としての梁ＢＭの一面から他面にかけて形成された貫通孔ＴＨ１を補強する補強金物５５０は、平面視で矩形形状の金属板からなる第１の板部材５６０と、金属円筒からなる円筒部材５７０と、平面視で矩形形状の金属板からなる第２の板部材５８０と、を備える。第１の板部材５６０は、梁ＢＭの一面（下面）に配設され、棒状の締結具としてのボルト部材２２０が貫通可能な貫通孔５６０Ａが形成されている。円筒部材５７０は、梁ＢＭの貫通孔ＴＨ１の全長に亘って嵌挿され、ボルト部材２２０が貫通可能である。第２の板部材５８０は、梁ＢＭの他面（上面）に配設され、ボルト部材２２０が貫通可能な貫通孔５８０Ａが形成されている。【選択図】図１３
