I roto i ngā mara o te hoahoanga me te miihini hanganga, ka pā nui te whiriwhiri rauemi ki te roa, te kaha, me te mahinga whānui o tētahi kaupapa. Ko tētahi rauemi kua aro nuitia i ngā tau tata nei ko te maitai EN 10219 S235JRH. E whakamārama ana tēnei Paerewa Pākehā i ngā tikanga tuku hangarau mō ngā wāhanga hanganga tuwhera kua whakarewahia matao, he porowhita, he tapawhā, he tapawhā rānei. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā painga o te whakamahi i te EN 10219 S235JRH me te take he whiringa pai tēnei nā te tini o ngā miihini me ngā kaihanga.
Te maarama EN 10219 S235JRH
Ko te EN 10219 S235JRH he paerewa mō ngā wāhanga hanganga tuwhera kua hangaia mātao, ā, kāore e hiahiatia he maimoatanga wera i muri mai. Ko te tikanga o tēnei ka hangaia te maitai i te pāmahana rūma, ka āwhina i te pupuri i ōna āhuatanga miihini, ā, ka whakarite hoki i te kounga teitei o te mata. Ko te tohu "S235" e tohu ana ko te kaha tuku iti rawa o te maitai he 235 MPa, e pai ai mō te whānuitanga o ngā tono hanganga. Ko te tohu "JRH" e tohu ana he pai te maitai mō te hanganga whakarewa, e whakarato ana i te whānuitanga o ngā mahi.
Ngā Painga o te EN 10219 S235JRH
1. Te ōwehenga kaha-ki-taumaha teitei
Ko tētahi o ngā painga tino kitea oEN 10219 S235JRHko tōna ōwehenga kaha-ki-taumaha teitei. Ko te tikanga ka taea e te rauemi te tautoko i ngā kawenga taumaha me te noho mama tonu, he mea tino pai mō ngā kaupapa hanga e tino hira ana te whakaiti i te taumaha. Mā tēnei āhuatanga ka taea te hanga hoahoa whai hua ake, ā, ka taea hoki te penapena i ngā utu rauemi me te tuku.
2. Te maha o ngā momo hoahoa
Kei te wātea te EN 10219 S235JRH i roto i ngā āhua maha (porowhita, tapawhā me te tapawhā), e hoatu ana ki ngā kaihoahoa me ngā kaihangarau te ngāwari ki te hoahoa i ngā hanganga e tutuki ana i ngā whakaritenga ataahua me ngā whakaritenga mahi. Ahakoa e whakamahia ana mō ngā mata o ngā whare hou, mō ngā anga pakari rānei mō ngā tono ahumahi, ka taea te whakarite i tēnei maitai kia tutuki ai ngā hiahia hoahoa rerekē.
3. He tino pai te whakarewa
E ai ki te tohu "JRH", kua hangaia te EN 10219 S235JRH mō ngā hanganga whakarewa. Nā tōna kaha whakarewa pai ka taea te whakauru pai ki roto i ngā kaupapa hanga maha, kia kaha ai, kia pono ai hoki te hononga. He tino whai hua tēnei āhuatanga i roto i ngā tono e tino hira ana te pono o te hanganga.
4. Te whai hua o te utu
Te whakamahiPaipa EN 10219ka taea te whakaiti i ngā utu i roto i ngā kaupapa hanga. Nā tōna kaha nui ka taea te whakamahi i ngā wāhanga angiangi, ka whakaiti i ngā utu rauemi me te kore e whakararu i te mahi hanganga. Hei tāpiri, mā te whai huatanga o ngā wāhanga hanga-matao ka whakaiti i te wā hanga, ka whakapai ake i te whai huatanga o te utu.
5. Te Oranga Tonu
I roto i te rāngai hanga o ēnei rā, he mea nui te whakaaro ki te pumau. He maha ngā wā ka hangaia te EN 10219 S235JRH mā te whakamahi i ngā tukanga taiao-hoa, ā, ka āwhina tōna āheinga ki te hangarua ki te whakaiti i te tapuwae waro. Mā te whiriwhiri i tēnei rauemi, ka taea e ngā kaihanga te whakarite i ā rātou kaupapa kia rite ki ngā tikanga pumau, ā, mā reira ka kukume mai i ngā kiritaki e aro ana ki te taiao.
Mō tā mātou kamupene
Kei te Tāone o Cangzhou, Porowini o Hebei tō mātou wheketere, ā, mai i tōna whakatūnga i te tau 1993, kua noho hei kaiārahi i roto i te hanga maitai kounga teitei. E 350,000 mita pūrua te rahi o te wheketere, e 680 miriona RMB te tapeke o ngā rawa, ā, e 680 ngā tohunga ngaio e whakapau kaha ana ki te whakarato hua pai rawa atu. Mā tō mātou tohungatanga ki te hanga EN 10219 S235JRH ka whakarite kia whiwhi ā mātou kiritaki i ngā rauemi e tutuki ana i ngā paerewa kounga me te mahi tino pai.
hei whakamutunga
Hei whakarāpopototanga, he maha ngā painga o te EN 10219 S235JRH, ā, he mea whiriwhiri pai tēnei mō ngā mahi hanganga. Nā tōna ōwehenga kaha-ki-taumaha teitei, tōna ngāwari ki te hoahoa, tōna ngāwari ki te whakarewa, tōna whai huatanga utu me tōna pumau, he mea tino pai tēnei rauemi mō ngā kaupapa hanga hou. Hei kaihanga matua, e whakahīhī ana mātou ki te tuku atu i tēnei rauemi maitai pai ki ō mātou kiritaki, hei āwhina i a rātou ki te whakatutuki i ā rātou whāinga hanga me te maia.
