Ngā Pūrongo - Ngā Rahi Paerewa o te H-Beam | Ngā Ahu o te HEA me te HEB mō te H Beam 400

Ko ngā kurupae-H he wāhanga maitai hanganga e whakamahia whānuitia ana i hangaia mā te huri wera. I ngā mākete o te ao, ko ngā kurupae-H te nuinga o te wā e tukuna ana e ai ki te Paerewa Pākehā EN 10034, e whakarōpūtia ana ngā kōtaha heiKurupae HEA H me te Kurupae Rino HEB.

Ka whakaratohia e tēnei tuhinga he tirohanga whānui hangarau tika mō ngā rahi paerewa o te hihi-H, me te arotahi motuhake kiKurupae HEAngā āhuatanga,Kōtaha kurupae HEB, me ngā rahi e whakahuatia whānuitia ana pērā i te H Beam 400 me te H Beam 400x400.

Te Whakamāramatanga o te Kurupae H Waro Rino Wera Hurihia

Ko te kurupae H maitai waro wera he wāhanga maitai hanganga me ngā flange whakarara me te whānui flange whānui ki te whakatauritea ki ngā kurupae-I tuku iho. Mā te tukanga hurihuri wera ka whakarite:

Ngā āhuatanga miihini ōrite

Āhuahanga whakawhiti-wāhanga pumau

He pai te whakarewa me te ngāwari ki te miihini

Te tutuki i ngā paerewa EN, ASTM, JIS rānei

Ko ngā kurupae-H te nuinga o te wā e whakamahia ana hei wāhanga amo kawenga i roto i ngā hanganga maitai.

Te Mārama ki ngā Rahi Paerewa o te H-Beam (Pūnaha EN)

I raro i te EN 10034, ka whakarōpūtia ngā hihi-H ki ngā raupapa rerekē, ko te nuinga:

Kurupae HEA H– wāhanga māmā ake

Kurupae maitai HEB– wāhanga taumaha ake

Ko te tau tohu (hei tauira, 400) e pā ana ki te teitei ingoa i roto i ngā mirimita, ehara i te rahi noa iho.

H Beam 400x400 – Te Whakamārama i te Kupu

Kurupae H 400x400e whakaahua ana i te hihi-H me:

Teitei ingoa ≈ 400 mm

Whānui o te flange ≈ 400 mm

I roto i te pūnaha paerewa EN, e rite ana tēnei āhuahanga ki:

HEA 400

HEB 400

He tata te whānui o ngā flange ki te teitei o ngā kōtaha e rua, ā, koinei te take e hokohokohia pinepinetia ai rāua heiNgā kurupae H 400x400, inā koa i roto i ngā tono pou. Heoi,he tino rerekē te matotoru me te taumaha tuturui waenganui i te HEA me te HEB.
