Document Type and Number:
Japanese Patent JP3849106
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent corrosion of a copper sheet roof caused by acid rain by providing a roofing board comprising a copper sheet and a sacrificial member on a boundary part between an eaves side copper sheet roof and a ridge side roof tile in a side-protected roof.
SOLUTION: A tile roofing board E is loaded on the upstream side of a dutch-lap roof B with copper sheets, and a downstream side end part of a roof tile A is loaded on a flat part of the tile roofing board E. In the roof tile sheet E, a sacrificial member 2 formed of zinc sheet, aluminum sheet, magnesium sheet or alloy sheet thereof, is loaded on a flat part of a body which is a bend copper sheet so as to be electrically connected to the body, an engagement piece 11 is erected on the upstream side of the body for flashing, and the downstream side is returned upwardly to stay rain flowing down from the roof tile A so as to promote the neutralization of acid rain, and the water overflows from an upper part and is discharged. Corrosion of the dutch-lap roof B caused by acid rain is prevented by the sacrificial corrosion of the roof tile sheet E, and no sense of incompatibility of the appearance is given. The service life of the sacrificial member 2 is about 10 years, but can be easily renewed.
