RAIN LEAKAGE PREVENTION METHOD IN TILE ROOFING SUBSTRATE WORK FOR TILE ROOFING WOODEN INCLINED ROOF

摘要

PROBLEM TO BE SOLVED: To provide an improved tile roofing substrate work generating less leakage of rain by fixing a sound large bar having a large section to portions of a rafter only by driving nails thereinto. ;SOLUTION: In tile roofing substrate work for a tile roofing wooden inclined roof, large hooking bars 11, 11 having a sectional size of at least not less than 36 mm × 30 mm are used. By use of stainless nails 14, 14, the bars 11, 11 are fixed to a rafter 6 through a caulking member 12, asphalt roofing 2 and sheathing roof board 7. Then there occurs no bend in the large bars 11 and thus the nails 14, 14 do not damage the asphalt roofing 2. Accordingly, there occurs no interference to a flow on the roofing 2 and no corrosion of the rafter 6 or sheathing roof board 7 caused by corrosion of nails.;COPYRIGHT: (C)2000,JPO
