TILE FIXING SCREW NAIL
PROBLEM TO BE SOLVED: To provide a screw nail capable of surely preventing infiltration of rainwater into a sheathing roof board by checking the infiltration of the rainwater into a nail hole of a tile as much as possible and improving extraction bearing force of the screw nail, in a tile fixing screw nail for fixing the tile over a batten cleat, an underlayment material and the sheathing roof board.SOLUTION: A tile fixing screw nail for fixing a tile 11 over a batten cleat 12, an underlayment material 13 and a sheathing roof board 14, comprises a shaft part 3, a head part 2 formed in a large diameter on one end of the shaft part 3 and a tip part 4 formed in a pointed shape on the other end of the shaft part 3. The shaft part 3 comprises a screw part 5a composed of a spiral projection strip 5a1 formed on one end side by continuing with a reverse surface just under part 2a of the head part 2 and a ring part 5b composed of a group of an annular projection strip 5b1 formed on the other end side, and a pitch P2 of the ring part 5b is formed smaller than a thickness T3 of the underlayment material 13.SELECTED DRAWING: Figure 4
【課題】瓦を桟木、下葺材及び野地板にわたって固定するための瓦固定用ねじ釘において、瓦の釘穴への雨水の浸入を可能なかぎり阻止すると共に、ねじ釘の引抜耐力を向上させ、野地板への雨水の浸入を確実に防止することができるねじ釘を提供する。【解決手段】瓦１１を桟木１２、下葺材１３及び野地板１４にわたって固定するための瓦固定用ねじ釘であって、軸部３と、軸部３の一端に大径に形成された頭部２と、軸部３の他端に先尖状に形成された先端部４と、を備え、軸部３は、頭部２の裏面直下２ａに連続して一端側に形成された螺旋状突条５ａ１からなるねじ部５ａと、他端側に形成された環状突条５ｂ１の群からなるリング部５ｂと、を有し、リング部５ｂのピッチＰ２が下葺材１３の厚さＴ３よりも小さく形成される。【選択図】図４
