Te hanga o te 500 x 500 mm Wāhanga Pokarua Tapawhā (SHS) he paearu mō te kaha ahumahi. Ahakoa he taonga noa ngā ngongo hanganga paerewa, nō roto ēnei wāhanga nui i tētahi akomanga hangarau "taumaha" motuhake. Ko te take i kore ai e taea e te nuinga o ngā whenua te tukatuka i ēnei paipa ko te whakakotahitanga o te kaha miihini, te urunga mai ki ngā rauemi mata, me ngā paerewa tiwhikete pakari.

Te Ahupūngao o te Hanga Matao: 3,000 Tāne Pēhanga

He wero nui te whakapiko i tētahi pereti maitai he 16 mm, 20 mm rānei te matotoru o te pakitara kia puta he kōtaha tapawhā koi, tika hoki. Hei whakatutuki i te koki-R (Radius Kokonga o Waho) paerewa-ahumahi, arā, 2.0-3.0t te tikanga, i runga i te paerewa, me neke atu i te 2500-3000 tana te pēhanga hanga o tētahi raina hanga.

He maha ngā wā ka raru ngā kaihanga iti iho i te "springback" me te pakaru o te kokonga. Mēnā kāore i te rawaka te pēhanga, ka porotaka rawa te koki-R, ka whakaiti i te horahanga papatahi e wātea ana mō te whakarewa hanganga. I roto i ngā kaupapa nui e whakamahi ana i te S355J2H, i teASTM A500Ko te Wāhanga C, ka taea e te koki-R hē te arahi atu ki te whakakorenga tonu o te papa e ngā kaihanga hanganga.

TeTe Wero Whakarato Kōiri Whānui-Ulunui

Ko te paenga ā-tinana o te paipa 500 x 500 mm he 2,000 mm. Kia whakaarohia te whānui o te hononga whakarewa me te tukanga hanga, me 2,150 mm ki te 2,250 mm te whānui o te koiri hurihuri wera tīmatanga.

• Te Herenga Ao Whānui:Ko te nuinga o ngā mira maitai ā-rohe (ina koa i te Tonga-mā-rāwhiti o Āhia me te Rawhiti o Waenganui) e whakahaere ana i ngā raina hurihuri e whakawhāitihia ana ki te 1,500 mm te whānui o te koiri. He iti noa iho ngā kaihanga maitai nui ka taea te hanga koiri whānui rawa atu i te 2,000 mm me te pupuri tonu i te hanganga matū me ngā āhuatanga miihini pumau.
• Te Tūturutanga o te Mekameka Tuku:He iti noa iho ngā "mira nui" i roto i ngā pokapū ahumahi nui ka taea te whakaputa i ngā koiri whānui rawa atu me te ōritetanga matū e hiahiatia ana. Mō te maha o ngā whenua, he iti ake te utu o te kawemai i te paipa 500 mm kua oti i te kawemai me te ngana ki te tukatuka i ēnei koiri whānui onge i te rohe.

Paearu Ahumahi: Yuantai Derun's 500×500 SHS

I roto i te āhua o te ao whānui onui diameter steel paipa, Yuantai Derunkua whakatūria hei tohunga matua i roto i te wāhanga tapawhā me te tapawhā 500 x 500 mm. Mā te whakamahi i te whakarewa auau-teitei (ERW) matatau me te hangarau hanga-makariri motuhake, ka mau tonu a Yuantai Derun i ngā manawanui tino pakari e kore e taea e te nuinga o ngā wheketere o te whare te taurite.

He maha ngā whakamahinga o ā rātou SHS 500 x 500 mm i roto i ngā kaupapa hanganga rongonui—mai i ngā taunga rererangi ki ngā tautoko o ngā papa tākaro—nā te mea ka whakarite te tukanga whakaputa kia ōrite te matotoru o te pakitara me te koki-R tino tika. He mea nui tēnei ōritetanga mō te "hangahanga modular," me uru pai ngā paipa ki ngā hononga kua oti te hanga i mua i te papa. Hei tāpiri, ko te kaha o Yuantai Derun ki te tuku i ēnei wāhanga i roto i ngā taumata pēnei i te maitai S355, Q355B ka waiho hei tohutoro matua mō ngā hoko o te ao.

Te Tikanga Whakarewa: Kei tua atu i te Paerewa ERW

I te tauine 500 mm, me tu te tukanga whakarewa ki ngā ahotea wera nui.

Te Whakarewa Auau-Teitei (ERW):He whai hua mō ngā matotoru tae atu ki te 16-20 mm, engari me whakamahi i te mana whakahaere aunoa tino matatau kia rite te kaha o te here ki te konganuku turanga.

Te Whakarewa Āwhata Ruku (SAW) / JCOE:Mō ngā mahi "matotoru rawa" (20 mm ki te 50 mm), ka whakamahia te tukanga JCOE. Ka hangaia te paipa kia rite ki te āhua "J", kātahi ka "C", kātahi ka "O", ka hangaia kia porowhita, ā, muri iho ka hangaia anō kia tapawhā mā te hanga pess taumaha.

He haumitanga miriona tāra tēnei taputapu e hiahia ana kia rere tonu mai ngā ota o te ao kia mau tonu ai te whai huatanga ohaoha—he nui te tono e kore e taea e te nuinga o ngā mākete o te kāinga te whakarato i a rātou anō.

Ngā Whakamahinga Noa o ngā Wāhanga Pokarua Tapawhā 500×500

E whakamahia whānuitia ana ngā paipa maitai tapawhā nunui i roto i ngā kaupapa hanganga taumaha e hiahiatia ana he kaha teitei me te ātete hurihuri.

• Ko ngā tono noa ko:
• ngā pou whare teitei
• ngā hanganga o te taunga rererangi
• ngā pūnaha tautoko tuanui o te papa tākaro
• ngā awheawhe ahumahi nui
• ngā kaupapa piriti me ngā hanganga
• ngā whare maitai modular

I roto i te maha o ngā kaupapa maitai hanganga e whakaatuhia ana e te hoahoanga, he pai ake ngā wāhanga tapawhā tuwhera nā te mea he ma, he hou hoki ngā āhua, me te pupuri tonu i te kaha o te hanganga.

Ngā Pātai Auau

1. He aha i whakamahia ai he SHS 500×500 mm hei utu mō te H-Beam? 

Ahakoa he tino pai ngā H-Beams mō te piko kotahi-angi, ka whakaratohia e te SHS (Square Poaka Wahanga) he ātete hurihuri ōrite. I roto i ngā pou kokonga teitei, i ngā hanganga rānei e pāngia ana e ngā kawenga hau maha-angi, ka tukuna e te SHS 500 x500 mm he ōwehenga kaha-ki-taumaha teitei ake, me te ataahua ma ake mō ngā hoahoa whare e kitea ana.

2He aha te rerekētanga i waenga i a S355J2H me Q355B mō ngā wāhanga nunui? 

He paerewa Pākehā a S355J2H (EN 10219) e hiahia ana kia whakamātautauhia te pānga i te -20℃, kia pai ai mō ngā āhuarangi makariri me te hangarau piriti. Ko te Q355B te paerewa Hainamana (GB/T 6728) e whakamatautauria ana i te 20℃. Mō ngā kaupapa o te ao i te EU, i te Middle East rānei, ko te S355J2H te whakaritenga ā-ture mō ngā mema kawe kawenga 500 mm.

3.Kei hea te nuinga o te wā e whakamahia ana ngā paipa tapawhā 500x500mm? 

Ko ngā SHS nui e whakamahia ana hei pou amo kawenga matua i roto i ngā whare teitei, i ngā taunga rererangi, me ngā awheawhe ahumahi nunui. Nā te mea he ma ō rātou rārangi, he tino pai hoki ēnei i roto i ngā kaupapa "Hanganga Rino Hanganga Whakaatuhia e te Whare" pērā i ngā papa tākaro me ngā pokapū huihuinga e kitea ai te anga rino e te marea.

4.He aha i teitei ake ai te utu mō ia tana mō ngā paipa 500x500mm i te utu mō ia tana mō ngā paipa 100x100mm? 

He nui ake te "utu tukatuka" nā te tere whakaputa iti o ngā mira taumaha me te utu nui ake o ngā koiri whaea whānui. Hei tāpiri, he nui ake te whakapaunga hiko mō te whakarewa auau-teitei o ngā pakitara 16 mm+, e whakaatuhia ana i roto i te utu FOB/CIF whakamutunga.
