rafter size 6 x 12 cm (edge length 6 by 12 centimeters) Explanation: edge length [math.] die Kantenlänge Pl.: die Kantenlängen feed size [tech.] die Kantenlänge Pl.: die Kantenlängen length of the edge [tech.] die Kantenlänge Pl.: die Kantenlängen http://dict.leo.org/ende/index_de.html#/search=Kantenlänge&s... „von je 6 auf 12 Zentimeter Kantenlänge“ should be read „von je 6 mal 12 Zentimeter Kantenlänge“, this means „edge length of 6 by 12 cm, each“. Description.- — Shape, lamellate. Size, 1 to 4 cm thick, 6 by 12 cm in area. https://archive.org/stream/proceedingsofuni811933unit/procee... A cube of edge length L= 2.6 cm is positioned as shown in the figure below. http://www.chegg.com/homework-help/questions-and-answers/cub... (Note: “edge length” is commonly used for cubes only) RAFTER SIZE RAFTER SPACING ON CENTER MAXIMUM SPAN 2” X 4” http://constructitall.com/9-uncategorised/972-maximum-span-c... NZS 3604:2011 Timber-framed buildings sets out how to size rafters in table 10.1. : Step 5 – Rafter size Read the rafter size in the left column of Table 10.1 for the 2.2 m span chosen. This indicates a 140 × 45 mm rafter size. http://www.buildmagazine.org.nz/articles/show/sizing-rafters... The maximum spans in the table above are for the horizontal distance the rafter can span (NOT the diagonal distance or actual length of the rafter). So if your house is 26 feet wide and the roof ridge beam is centered on the house, you will need a rafter that can span 13 feet. Let's use this example and find a size of rafter that will work. Looking through the center of the table, we can find a couple of options. The table states that 2 X 6 rafters spaced 16 inches on center (o.c) can span a maximum distance of 13 feet 5 inches. Another option are 2 X 8 rafters spaced 24 inches o.c. http://www.the-house-plans-guide.com/roof-rafter.html (Note: sizes in inches) R804.3.2.1 Minimum roof rafter sizes. Roof rafter size and thickness shall be determined in accordance with the limits set forth in Tables R804.3.2.1(1) and R804.3.2.1(2) based on the horizontal projection of the roof rafter span. For determination of roof rafter sizes, reduction of roof spans shall be permitted when a roof rafter support brace is installed in accordance with Section R804.3.2.2. The reduced roof rafter span shall be taken as the larger of the distance from the roof rafter support brace to the ridge or to the heel measured horizontally. For the purpose of determining roof rafter sizes in Tables R804.3.2.1(1) and R804.3.2.1(2), wind speeds shall be converted to equivalent ground snow loads in accordance with Table R804.3.2.1(3). Roof rafter sizes shall be based on the higher of the ground snow load or the equivalent snow load converted from the wind speed. Rafter spacing (inches) 16 24 16 24 16 24 16 24 http://publicecodes.cyberregs.com/icod/irc/2012/icod_irc_201... -------------------------------------------------- Note added at 4 hrs (2016-01-10 22:43:49 GMT) -------------------------------------------------- I do prefer "size" and would avoid "edge length", as this refers to a square in geometry. |

Reference Reference information: Bei diesen Sparrenabständen ergeben sich bei Vollholz statisch notwendige Sparrenabmessungen zwischen 6/12 und 10/20 cm. https://de.wikipedia.org/wiki/Sparren |
