Te Tāngata: Tāngata toko i te rino A992 (kore tēnei e whai pānga ana ki te rino nui; ā, nā tēnei e awhina nei i a mātou i roto i te waeawe) Nō te nuinga o ngā whare, ngā tāhuna me ērā atu whare hanga nui kua kitea e mātou i aianei ka whakamahia te rino whakatūpato i waenganui i ētahi atu momo whakamahinga. Nā ngā pūkaha me ngā hanga, nā rātau e hanga me te whakatū mai o ēnei whare hanga nui e kī nei, ka whakamahia tēnei tāngata nā runga i te hiranga iti noa i te rino ki te weu e āhei ai te whakamahi i waenganui i ētahi atu momo. Ko te whakamahia nui o tēnei nui raweke hei whiringa pai mō te nuinga o ngā hunga hanga.
He whakariterite te aho A992 o te toto mo te hanga whare o Amerika, me ona hiranga nui ake i te katoa o nga aho toto kotahi ke, penei i nga aho A36 ranei, ko te A572. Ko tenei he mea e taea ana e ia te whanake i te mohiotanga o te taumata o te manaaki i te nui o nga rauemi, me te tirotiro haere i te pai rawa o te hopu i te mate. Hei tētahi take, ko tēnā te take i te pai ai ki te whakamahia hei whakangungu mo nga whare; pēnei i nga pou me etahi atu (he mea nui enei ka whakatūria i te katoa). Kaore i te mohio he mea nui noa iho te pou o etahi whare tu tonu, ka whai wawe nei i te toto A992.
He mea nui rawa te kauwhango maero ASTM A992 e tuku nei mā mātou. E āhei ana ō rātou rauemi ki te noho he I-beam, H-beams rānei, he W beam rānei. He mea nui tō rātou rangatiratanga me te wawara o te hunga hanga e tae ana mai i ngā rahi me ngā āhua. Ko tērā he paihere mātauranga, nā te mea ka taea e ngā kauwhango te whakaaroaro i te nui o ngā taumata, kāore i te whakaputu rānei i te tahū i ngā wā hē.
Kei ngā whakaiti moni i te kōwhiringa ki te whakamahi i te toto ASTM A992 e tēnei tōnū tētahi o ngā rahi rawa. He whanake (kāore i te nui) ā, he iti noa iho ngā mea toto e hīrahi ana kia piki ngā nui nui a ngā hangaanga. Ko tēnei hei whakangū kia iti ake ngā utu e pā ana ki ngā hua e hango nei mō tētahi wā hanga. Nā tēnei, ka mate haere ngā hangaanga ki te whakaiti i ō rātau moni hua.
He mea hou ke ētahi atu o ASTM A992 toto, ko tēnei hoki he pai rawa i te taiao. I hanga mai i te 100% o ngā hua whakahokia, ko tēnei e mahi nei i tōna wā kia heke ngā waipiro. Ko tēnei anō ka whakahokia i te mutunga i te korenga o tana whakamahi. Nā tēnei, ko tēnei he hua whakahaere tonu ake rawa tonu i ētahi atu o ngā hua hangaanga kāore rawa e pai ana i te taiao.
Nō te wāeke o te whēako paemahara me ngā whare hou e hanga nei, ko tētahi mea mōhio koe ka hikangia e mātau ngā rauropi nui i te rahi nui i runga i a mātau, ko tēnā te take i he ai ko te A992 steel he mea pai hei whakauru ki te tūnga o ngā mahi e hiahiatia ana te whakamahi o ngā I-Beams. Kaore i te whakapae mai ki ngā whare anake, ka whai pāti anō hei whakamahi hei āhua pai mō ngā pōhatu me ērā whare whakahaere matua kē.
Ko te A992 steel he mea wātea rawa, ahakoa iti rawa te utu ki te hanga mā te tuhinga hou i tēnei wā, i mua atu i ngā tau. Nā tērā, kei te nui ake ngā hangaanga e āhei ana ki te whakamahi i a ia. Ko tēnei rauropi nui e āhei ana ki te hanga pūtake mō ngā whare e hanga nei kia noho tonu i ā rātou āheinga kotahi ki te tūmomo hou, ā, ki te whakamahi ake e ngā hangaanga ki enei whare rangi hou ki ērā wā e heke mai nei, ka whiwhi haere i te tiaki.
Ka mahi tātou i waenganui i tētahi nui atu o ngā maomao tōrutoru, ka tiakina te pai o ngā hua katoa i mua i te whakahoro, ko te pai te taunaki. Ko ngā hua nui ko ngā tāngata katoa o ngā paemahi tōrutoru (ERW/SSAW/LSAW/ astm a992/pīri tika/seamless pipe/tōrutoru kauwhango), korowai (tirohanga Amerika, tirohanga Rangiātea, tirohanga Australia H-beam steel), tāngata, Angle steel, flat steel, steel sheet piles, ngā tūtohu katoa o ngā roa tōrutoru me ngā rorohiko, strip steel, scaffolding, taura tōrutoru, pere, eta.
Ka taea e mātou te tuku i ngā pūkorero taurangi o Amerika/Riponihia/Australia, ngā pūkorero taurangi a ASTM A992, ngā pūkorero taurangi o Hapani, āe me ngā ratonga whakarerekē pukapuka hoki, pērā i te kōwhiti me te tapa. Nō reira ka horoia ēnei mahi ki te Uetika Tawhiti me Oceania i tenei wā. Kua horoia hoki ki Taepa Tonga, Tai Hauāuru, Afirika, me te Mīhini Ati, Afirika, me te Mīhini Ati, āe me Afirika.
Kei a mātou tētahi kaiwhakahaere toitū mo nga take taonga me te matauranga matua o nga raraunga, ko te tuhituhi kotahi hei whakamana i a koutou i runga i nga mahi pai. Kei a mātou te hunga matua o ASTM A992, e noho ana i waenga o nga wa o te ra katoa hei whakamana i a koutou i roto i nga patai me etahi atu hekenga e pa ana ki a koutou. Ko tā mātou nā, ka taea e mātou te whakaaetanga he haerenga pai mo koutou.
ko te whakahaere ASTM A992, he 17 tau ngā kaiwhakamahi i roto i te mahi whai take ā-motu mō ngā rākau maero. Tēnā ka taea e mātou te whakarite o nui atu o ngā pūkeko me ngā aho. Ko tētahi atu hiranga, kei a mātou he takiwā o ngā tohunga take ā-motu, kotahi mai i te whakarite ā-wāriu, hei whakamana i a koe i ngā whakatau matua me ngā tautoko. Mēnā ka uiui ake koe i ngā take ki a mātou, ko te take ka heke i te utu!
