Document Type and Number:
Japanese Patent JP2023137195
Kind Code:
A
Abstract:
To provide a fixture for a roofing material or the like capable of preventing occurrence of deterioration of packings by preventing the mutual contact of two packings arranged by sandwiching a washer therebetween, and capable of maintaining both the suppression of vibration of a corrugated plate and water cut-off in an insertion hole part of the washer over a long period of time.SOLUTION: A fixture for a roofing material comprises a screw 5 provided with a head part 3 at one end of a shaft part 2 and a sharpened end 4 at the other end, and a washer 6 and a packing 7 attached to the shaft part 2 of the screw 5. The packing 7 is composed of a combination of an upper packing 7a externally fitted and attached to a position on the head part 3 side of the screw 5 and a lower packing 7b externally fitted and attached to a position on the sharpened end 4 side of the screw 5, which sandwich the washer 6 inserted into the shaft part 2 of the screw 5, with respect to the shaft part 2. The upper packing 7a and the lower packing 7b are different in hardness from each other, and the upper packing 7a is smaller in diameter than the lower packing 7b so that contact areas with the washer 6 are different from each other.SELECTED DRAWING: Figure 1
