Te tohu me nga kupu
•I te United States,Steel I KurupaeKo nga mea ka tohua ma te whakamahi i te hohonu me te taumaha o te kurupae.Hei tauira, ko te kurupae "W10x22" he tata ki te 10 in (25 cm) te hohonu (te teitei ingoa o te kurupae-I mai i te mata o waho o tetahi flange ki te mata o waho o tetahi flange) me te taumaha 22 lb/ft (33). kg/m).Me tohu ko te waahanga flange whanui he rereke te rereke mai i te hohonutanga.I roto i te take o te raupapa W14, ka rite pea ki te 22.84 in (58.0 cm).
•I Mehiko, ka kiia nga kurupae-I rino he IR, ka tohua ma te whakamahi i te hohonu me te taumaha o te kurupae i roto i nga tikanga ine.Hei tauira, ko te kurupae "IR250x33" he tata ki te 250 mm (9.8 in) te hohonu (te teitei o te kurupae-I mai i te mata o waho o tetahi flange ki te mata o waho o tetahi flange) me te taumaha tata ki te 33 kg/m (22). lb/ft).
Me pehea te ine:
Teitei (A) X Tukutuku (B) X Whānui Flange (C)
M = Steel Junior Beam or Bantam Beam
S = PaerewaSteel I Kurupae
W = Paerewa Whanui Flange Beam
H-Pile = H-Pile Beam
