How to calculate the wattage of the sloping roof?
(a) tile roof, according to the size of the graphic design to calculate the inclined area. The area occupied by chimney, lampblack machine base, air duct, small louver and inclined ditch on the house is not deducted, and the eaves area of small louver does not increase; The area of the overlapping part between the skylight eaves and the roof should be included in the calculation of the roof quantity.
(2) GRC roofing and galvanized iron roofing are calculated according to the actual paving area.
(3) The tile laying and tile laying quantities of the antique roof are calculated according to the graphic design size and actual paving area of the roof; The area occupied by the roof is not deducted, and the area occupied by the roof should be deducted when calculating the roof quantity. The calculation method of ridgeline area is to multiply the width of ridgeline by the length of ridgeline and then by the length of folded waist tiles on both sides of arc length. (4) The quantity of the roof (including the ridge crossing) is calculated in linear meters, and the root length of the snout (beast), middle pile (treasure top), vertical ridge head and claw angle tip (claw angle leaf) is deducted. When the practices, materials and heights of ridges are different, the quantities should be calculated separately.
(5) The quantities of nails, tiles, eaves and accessories shall be calculated as linear meters; Hard mountain and suspended mountain buildings are counted as the skin of Bofeng, and the claw angle is calculated according to the length of the outer edge line of the overhanging eaves.
(6) The ridge with water is calculated as the extension meter, and the outer skin of the ditch head is calculated to the center line of the ridge. (seven) the length of the ridge is calculated by hanging the tip skin. (8) Ridge, kiss (beast), middle pile (treasure top), vertical ridge head and claw leaf are all considered as "one". (9) Hammer ash clay sculpture and ridge (viscoplastic) shall be calculated as "m2". (10) The wall cap is calculated as "extension meter" according to the center line of the wall.
(eleven) the quantities of fan-shaped tile heads and fire rings on the eaves are calculated by "extended meters".
(12) FRP tile roof, metal profiled steel plate roof and sunshine board roof are calculated according to the actual paving area.
(thirteen) membrane structure roof, according to the design graphic size to cover the horizontal area.
