Whakarāpopototanga Whakahaere

Mō ngā kaupapa EPC o te ao,EN 10219(Paerewa Pākehā) meSAC GB/T 6728(Paerewa Hainamana) tautuhia ngā wāhanga hanganga kōhao kua whakarewahia i hangaia i te makariri e rite ana ki te hangarau (RHS, SHS, CHS). I aS355JRhei te kaupapa matuahe rite te taumata Hainamana ki te Q355Bnā te mea he rite tonu te kaha hua o te 355 MPa, ko te whakaaetanga a ngā kaitohutohu kaupapa e whakawhirinaki nui ana ki ngā hanganga matū kua manatokohia,EN 10204 3.1 MTCte whai i ngā hanganga, me te tutuki i ngāEN 1993 (Eurocode 3)Hei te tihi o Hainakaiwhakarato wāhanga hanganga tuwhera, Yuantai Derun RōpūKa whakaratohia he whakamārama whānui e ahu mai ana i ngā raraunga o ngā rerekētanga hokohoko matua e 5 i raro nei hei āwhina i a koe ki te whakatere i ngā tukunga paerewa-maha me te arotau i tō tahua.

[Whakahōu Paerewa Hou]Kua whakahoutia mana e Haina tana paerewa hanganga matao kiGB/T 6728-2025Hei arotake i te pānga o ēnei whakahoutanga whakarewa me te manawanui hou ki ō hoahoa hangarau o nāianei, ki te whakataurite ki ngā paerewa Pākehā, pānuihia tā mātou tātaritanga motuhake i konei:Tikiake me te Aratohu Whakataurite PDF a GB/T 6728-2025.

Mō ngā tono kaupapa e kaha ana, ka taea hoki e koe te tuku tika i tō Pire Rauemi (BOM) ki tā mātou tēpu arumoni i raro nei hei aromatawai paerewa kua whakaritea.

1. Anga Whakahaere: EN 10219 me GB/T 6728 Te Rerekētanga i roto i ngā Kirimana o te Ao

Te mārama ki te whānuitanga ture me te mana hanganga o tētahiTe rerekētanga o te EN 10219 me te GB/T 6728he mea nui hei ārai i ngā whakahēnga hanganga ture i te wā o ngā arotake kaupapa o te ao.

CEN EN 10219:E whakaatu ana i ngā tikanga tuku hangarau mō ngā kōtaha hanganga whakarewa-makariri. E hiahiatia ana tēnei paerewa mō ngā hoahoa hanganga i tātaitia i raro iEN 1993 (Eurocode 3).

SAC GB/T 6728:E whakaatu ana i ngā ine, te āhua, te taumaha, me ngā rerekētanga e whakaaetia ana i roto i te anga paerewa ā-motu o Haina mō ngā tono hanganga whānui, mō ngā tono amo kawenga rānei.

Ahakoa e whakahaere ana ngā paerewa e rua i ngā āhua hanganga ōrite, he rerekē ngā pūnaha rauropi kaupapa e mahi ana. I roto i ngā hanganga ā-rohe o Ūropi, ā-iwi rānei, kāore e taea te whiriwhiri i te EN 10219 nā runga i ngā ture haumaru ā-rohe. Heoi, i roto i ngā hanganga ahumahi ā-ao e whakahaerehia ana e te EPC, ngā whare kua oti te hanga, me ngā anga whakairinga pūngao rā, ka whakaaetia te GB/T 6728 mā te whakakapinga hangarau.

Hei te ao matuaKaiwhakarato RHS SHS mō te EPCngā kaupapa, ka whakahaerehia e te Yuantai Derun Group he putanga ā-tau o10 miriona tāne, me te whakarite kia tutuki katoatia ngā whakaritenga tuku hangarau ahakoa te paerewa e whakahaua ana e tō kirimana.

2. Taurite o te Karaehe Rino: Ngā Āhuatanga Ā-ringa Taurite o te Q355B me te S355JR

Ko te tino raruraru i ngā wā tukunga paerewa-whakawhiti ko te tautuhi i tētahi mea ponoQ355B me te ōrite ki te S355JRmatihiko. I roto i te whakatauira hanganga,Q355Be tātarihia whānuitia ana hei tauira taketake ki te PākehāS355JR.

Ripanga Tohutoro Hangarau: Ngā Tawhā Hangarau me ngā Herenga Matū

Hei whiwhi whakaaetanga a te kaitohutohu hanganga, me arotake e ngā tīma hokohoko ngā tawhā matū me ngā tawhā miihini tika e whakaritea ana e ngā paerewa e pā ana (mō te matotoru ingoa ≤16mm:

3. Ngā Āheinga Ahu: Ngā Rahi me ngā Rerekētanga o te Rino RHS SHS CHS

Haunga te mahi whakarewa matū, he rerekētanga tika i roto iRHS SHS CHSngā rahi me ngā inenga maitaie whakatau ana i te angitu o ngā huihuinga modular tino tika me ngā whakaurunga aunoa i te papaanga. Mō ngā kōtaha tuwhera me te roa taha ingoa (b, h) i roto i te awhe 100 mm-200 mm, ka whakaatuhia e ngā ātete āhuahanga ngā rerekētanga motuhake:

Te Manawanui ki te Matotoru o te Pakitara:E tohu ana te EN 10219 i te manawanui o te ±10% mō ngā kōtaha whakarewa (me te rohe mōrahi e herea ana ki te ±2mm), engari ko te GB/T 6728 e whakaae ana i te manawanui paerewa ± 10% e āhei ai te matotoru pakitara ā-rohe i raro i te tuku i runga i ngā whakarōpūtanga iti motuhake.

Te Pūtoro Kokonga o Waho (R):Mō ngā matotoru pakitara t ≤ 6mm, ka whakawhāitihia e te EN 10219 te radius kokonga o waho ki te awhe i waenga i te 1.6t me te 2.4t, engari e whakaaetia ana e te GB/T 6728 te awhe whānui ake o te ≤ 2.0t. Ko te tikanga o tēnei, he piri ake ngā kōtaha Pākehā ki ngā rohe pūmau ariā.

Te Hurihuri Tahuri:Ka whakamanahia e te EN 10219 ngā rohe pakari, ka whakawhāiti i te miro ki te ≤ 2mm + 0.5mm/m. I tetahi atu taha, ka whakaaetia e te GB/T 6728 te 1.5mm/m, arā, 0.15% o te roa katoa.

Hei whakakore i ngā hapa i te wā o te tirotiro QA/QC taumata-papa, he mea nui ngā tikanga ine tika. Hei tauira,Me whakanoho rautaki ngā calipers kia matara atu i ngā taha tapahi o ngā kōtaha kia kore ai e pokanoa ngā burr.Mā te ine tika i te taha ka puta he rerekētanga o te tapahi ā-rohe, ā, ka puta he piko hangai ki ngā raraunga matotoru o te pakitara nā ngā koki moroiti.

4. Whakapūmau Kounga: EN 10204 3.1 MTC me te Aroturukitanga o te Whakaputa Tau-Wera

Mō te tutuki i ngā whakaritenga o ngā kaupapa o te ao, he mea nui te mekameka tuhinga e whakamana ana i te takenga mai o te rauemi me ōna āhuatanga ā-tinana. Me tino manatoko te whai i ngā tuhinga e tukuna ana kia tutuki i ngā paerewa katoa.

I raro i ngā tikanga hokohoko e whakamanahia ana e te Eurocode, me whakarato e ngā kaihanga he tuhinga kua whakamanahia katoatiaEN 10204 3.1 Tiwhikete Whakamātautau Rauemi (MTC). Mā tēnei tuhinga ka oatitia te ū o ngā tātari matū me ngā whakamātautau ā-ringa ki te paerewa e tonoa ana.

E hangai ana ki ngā ture aroturuki pakari a ngā kaimahi kirimana EPC o te ao, ko te whakapūmautanga kounga i roto i tētahi mira hurihuri matao ngaio e ahu mai ana i te meka ko ngā āhuatanga whakarewa e whakatauhia katoatia ana e te koiri maitai matua. Nō reira, ko ngā rerenga mahi whakahaere kounga i Yuantai Derun Groupe hono tika ana ki te Tau Wera o ngā rauemi mata.

Hei whakarite i te manatoko katoa i te papa o te kaupapa, ka tukuna atu ngā Tiwhikete Whakamātautau Rauemi EN 10204 3.1 e rite ana me ngā tuhinga tuku me ngā utanga, e rite ana ki ngā Tau Wera rauemi mata e whakaaturia ana i runga i ngā tohu paihere hua. Mā tēnei tukanga tuhinga māmā ka taea e ngā kairūri whenua te manatoko tonu i te hanganga matū me te tātari koko ki tō pire rauemi, ka whakakorea ngā āputa tuhinga e whakaroa ana i ngā arotakenga papa o te ao.

5. Te Whakatutukitanga Tauhokohoko: Te Tohu CE me te Whakahaere Mōrearea Ārai-Tukunga

He nui te awe o te whakaiti i ngā mōrearea arumoni, ngā rohe whakahaere rauemi, me ngā ture tauhokohoko o te ao ki te whakaae ki ngā rauemi.

Ko te arai matua i roto i te rapu rauemi whakawhiti-paerewa ko te tiwhikete ā-rohe. Ko ngā kaupapa e herea ana e ngā ture o te Kotahitanga o Ūropi me whai manaTohu CE mō ngā wāhanga hanganga maitai tuwheraMena kāore i te kaihanga te arotake Mana Whakaputa Wheketere (FPC) e hiahiatia ana hei tuku i tētahiEN 10219Ka kore e whai tikanga ture te tohu CE, te ōritetanga hangarau rānei, i ngā tari taake.

Kei te pupuri tonu a Yuantai Derun Group i ngāTohu CE (EN 10219-1), BC1 (Hīngapōra), meISO 9001/14001/45001ngā tiwhikete, e āhei ai te whakawātea maeneene puta noa i ngā tauranga o Ūropi me te ao.

Me tika hoki te whakamahere rautaki kia pai ai te whakahaere i tō mahi whānuiutu wāhanga kōhao maitai mō ia tanaHe tino pai tā mātou tīma kaipuke ki te whakanui ake i ngā utanga mā te whakamahi i te paerewaNgā ipu 20GP (kia mōhio koe he rerekē rawa ngā whakatakotoranga ipu 20GP mai i ngā momo ipu High Cube/HQ i te teitei me te kaha o te rōrahi)hei whakarite i ngā here o te rohe mō te tauranga, me te ārai i ngā whakaroa ohorere i te whakahaerenga o ngā kaipuke.

Te Mahere Whakarāpopototanga: Anga Whakatau Kaupapa

Ngā Pātai Auau (FAQ)

P1: Ka taea e GB/T 6728 Q355B te whakakapi i te EN 10219 S355JR?

A1:Ae, āe. Ko te kaha whakaputa o ngā momo e rua he 355 MPa, ā, he rite tonu te mahi i roto i ngā anga hanganga paerewa. Heoi, me whakaae te kaitohutohu hanganga me te manatoko i ngā rohe manawanui motuhake mō te kaupapa, ki te whakakapinga tika.

P2: He aha te rerekētanga hanganga matua i waenga i te S355J2 me te Q355D?

A2:E rua ngā tohu matatau i hangaia mō ngā taiao pāmahana iti.S355J2e hiahiatia ana te kaha pānga iti rawa o te 27 Joules i te -20°C, i te wāQ355De hiahiatia ana te iti rawa o te 34 Joules i te -20°C. I roto i te mahi ngaio, ka tutuki, ka hipa rānei a Q355D i ngā paearu pānga o S355J2, ā, he rite tonu ki te hangarau.

P3: Ka taea e te kaiwhakarato wāhanga hanganga tuwhera i Haina te whakarato i ngā EN 10204 3.1 MTC mō GB/T 6728?

A3:Āe. Mā ngā kaihanga Tier-1 pēnei i a Yuantai Derun e whakahōputu ngā pūrongo whakamātautau mira katoa kia rite ki ngā paerewa EN 10204 3.1, ahakoa te whakaritenga hanga, kia taea ai te whai raraunga paerewa mā ngā kairūri o te ao.
