Svařované lisované rošty SP


Tabulka zatížení SP

pro odporově svařované rošty
oko 34,3 x 38,2 mm
Ocel S235 JR (ST 37-2)
Přípustné pnutí = 23,50 kN/cm2

FP = maximální zatížení [kN] silou působící ve středu zatěžované plochy o rozměru 200 x 200 mm,
f = průhyb [cm] při uvedeném plném zatížení
FV = maximální zatížení [kN/m2] u plošně a rovnoměrně rozloženého zatížení,
fV = průhyb [cm] při uvedeném plném zatížení

Uvedeny jsou charakteristické hodnoty (skutečná užitná zátěž). Dle RAL-GZ 638:09/08 tyto hodnoty obsahují následující faktory pro bezpečnostní rezervu výpočtu:
Účinek γQ = 1,5
Vlastnost materiálu γM = 1,0

nepochozí

pochůzné, s 1,5 kN, průhyb f 1/200 vzdálenosti opěr, maximálně však 0,4 cm nebude přitom překročen.

I přes dostatečnou nosnost je pochůznost limitována maximální hodnotou průhybu uvedenou v normě. (zesílená čára ohraničuje hraniční hodnoty)
