Calculation Methods of Standard Surface Area of Flat Roofs for Internal Wasteway through Cast Iron Pipe and Funnel Set-point Diameters in the Transcarpathian Region
Journal Title: Металлические конструкции - Year 2017, Vol 23, Issue 1
Abstract
The calculation of standard surface areas of flat roofs made by SNiP II-32-74 and DBN V.2.5-75 2013 and according to data III B and IV climatic regions excluding the results of observations of precipitation at 9 weather stations of Transcarpathian region. For the standard surface area calculation of flat roofs it is suggested using materials observations of rainfall in 1889–2014 years in at 9 weather stations of the Trans¬carpathian region with appropriate heights above the Baltic Sea: Coast – 113.0 m, Uzhhorod – 114.6 m, Big Bereznyj – 209.0 m, Hust – 166.0 m, Rachel – 438.0 m, Intermountain – 456.0 m, Lower Gate – 500.0 m, Lower Jelly – 615.0 m, Play – 1 330.0 m. To calculate rainfall parameters for settlements, peaks and bridgewalls of Carpathians it has been suggested using 23 areas between 9 weather stations and 18 transition stations for which precipitation parameters defined at least in two directions between stations and altitude rainfall efficiency. In particular, it has been calculated the rainfall parameters for the 8 peaks of Carpathian Mountain: Valley Llevel – 1 470 m, Big Top – 1 598 m, Tempe – 1 634 m, Unharyaska – 1 707 m, Syvulya, Thick – 1 818 m, Pip Ivan – 1 936 m, Petros – 2 020 m and Goverla – 2 061 m. The calculation of rainwater parameters for cast-iron water pipes and funnels has been made in four areas: Coast – Playa, Uzhgorod – Playa, Hoost – Play, V. Bereznyy – Play. For the purpose of legal practice areas of flat roofs for cast-iron pipes and funnels offered peg 13 districts of Transcarpathian region 9 weather stations.
