REINFORCING STRUCTURE OF JOINT PART OF WOODEN STRUCTURE PROVIDED WITH FRACTURE CONFIRMATION PORTION
To provide a reinforcing structure of a joint part of a wooden structure capable of easily discriminating fracture from the outside and fracturing in a fracture mode having high ductility.SOLUTION: In a reinforcing structure of a joint part of a wooden structure for joining a plurality of structural materials (a foundation 2, a base 3, and a column 4) of the wooden structure, an FRP sheet 5 having reinforcing fibers formed by laminating a single layer or a plurality of layers of unidirectional fiber materials or bidirectional cross fiber materials is attached to surfaces of the plurality of structural materials (the foundation 2, the base 3, and the column 4) over the plurality of structural materials. A fracture confirmation part A capable of confirming whether or not a joint part is broken is provided in a part of the FRP sheet 5. The fracture confirmation part A is mechanically fixed to the structural material (the foundation 2) by a screw 6 without bonding the FRP sheet 5 to the structural material (foundation 2), and the number of layers of reinforcing fibers and the number of screws are set so that fracture of the FRP sheet 5 around the screw 6 precedes other fracture.SELECTED DRAWING: Figure 1
【課題】破壊が外部から簡単に判別できるとともに、延性の高い破壊モードで破壊される木構造物の接合部の補強構造を提供する。【解決手段】木構造物の複数の構造材（基礎２、土台３、柱４）を接合する木構造物の接合部の補強構造において、一方向繊維材若しくは二方向クロス繊維材を単層又は複数層積層した補強繊維を有するＦＲＰシート５を、前記複数の構造材（基礎２、土台３、柱４）に亘ってそれらの表面に取り付け、ＦＲＰシート５の一部に接合部が破壊したか否かを確認できる破壊確認部Ａを設け、破壊確認部Ａを、ＦＲＰシート５が構造材（基礎２）に接着されずに、ビス６で機械的に構造材（基礎２）に止め付けられているものとし、ビス６の周囲のＦＲＰシート５の断裂が他の破壊より先行するように補強繊維の層数及びビスの本数を設定する。【選択図】図１
