FASTENING MEMBER AND CONSTRUCTION MEMBER
PROBLEM TO BE SOLVED: To obtain a fastening member capable of restricting the increment of insertion torque even in applications to penetrate the combination of waterproof application high viscosity rubber and lumber.SOLUTION: A fastening member comprises: a wood screw 10 for fixing a bracket holding a solar cell module on a roof; a washer 21 into which a shaft part 12 of the wood screw 10 is inserted so as to come in contact with the bracket; and a water proof packing 22 for making waterproof between the wood screw 10 and the washer 21, in which the wood screw 10 includes: a bow 11 receiving a rotational force; the shaft part 12 having a columnar shank; a screw tip part having a cone shaped shank; a double-start thread extending across the screw tip part and the shaft part 12; and at least four V-shaped grooves formed on the screw tip part in rotational symmetry around the rotational axis of the shank and at equal intervals so as to extend to the distal end of the screw tip part, so that a screw-in object member is bored with edges of the V-shaped grooves by rotating the screw with the rotational force received on the bow 11.SELECTED DRAWING: Figure 5
【課題】防水用途の高粘性ゴムと木材とを合わせて貫通させる用途においても挿入トルクの増加を抑える締結部材を得ること。【解決手段】太陽電池モジュールを保持するブラケットを屋根に固定するための木ねじ１０と、木ねじ１０の軸部１２に挿入され、ブラケットに接するワッシャ２１と、木ねじ１０とワッシャ２１の間を防水する防水パッキン２２とを備えたことを特徴とする締結部材であって、木ねじ１０は、回転力を受ける頭部１１と、シャンクが円柱状の軸部１２と、シャンクが円錐形状であるねじ先部とを備え、ねじ先部及び軸部１２に跨る二条ねじを有し、ねじ先部に、シャンクの回転軸を中心とした回転対称かつ等間隔で、ねじ先部の先端まで延びるように少なくとも四つ形成されたＶ字形状の溝を備え、回転力を頭部１１で受けて回転することによって、ねじ込み対象部材にＶ字形状の溝の縁で穿孔する。【選択図】図５
