Kurupae H Rino, i tapaina mō ō rātou tapanga whakawhiti āhua "H", he rauemi maitai tino whai hua, he ohanga hoki, he painga pēnei i te ātete piko kaha me ngā mata flange whakarara. He whānuitia te whakamahinga i roto i ngā mara maha, tae atu ki te hanga, ngā piriti, me te hanga mīhini. I roto i ngā paerewa maha o ngā kurupae-H, ko ngā kurupae-H kua tohua i roto i te ASTM A992 e tu ana mō ā rātou mahi tino pai.
Ko ngā kurupae-H ASTM A992 te maitai hanganga e whakamahia whānuitia ana i roto i ngā whare o Amerika, he kaha teitei, he pakari hoki. Me te kaha tuku iti rawa o te 50 ksi (tata ki te 345 MPa) me te kaha kume i waenga i te 65 me te 100 ksi (tata ki te 448 me te 690 MPa), ka taea e rātou te tu atu ki ngā kawenga taumaha, ā, he pai te kaha whakarewa me te ātete ru. Nā tēnei kaASTM A992 H kurupaete rauemi whiriwhiri mō ngā kaupapa nui pēnei i ngā whare teitei me ngā piriti nunui.
I roto i ngā rahi rerekē o te ASTM A992 H-beam, ko ngā rahi 6*12 me te 12*16 ngā mea tino noa.
He whāiti te whānui o ngā kurupae H whakarewa 6*12, ā, he teitei taurite, he pai rawa atu mō ngā mahi ōhanga me ngā mahi whai hua. I roto i te umanga hanga, he maha ngā wā ka whakamahia i roto i ngā wāhanga hanganga pērā i ngā kurupae tuarua me ngā purlin i roto i ngā whare noho me ngā whare arumoni, e tohatoha ana i ngā kawenga whare me te whakarite i te pumau o te hanganga. I roto i ngā whare ahumahi iti, he maha hoki ngā wā ka whakamahia ngā kurupae-H 6*12 hei tautoko i ngā hanganga tuanui me te whakatutuki i ngā whakaritenga kawenga.
He nui ake ngā rahi whakawhiti me te kaha kawe kawenga o ngā kurupae H hurihuri wera 12*16. I roto i te hanganga piriti nui, ka mahi rātou hei kurupae kawe kawenga matua, e mimiti ana i ngā kawenga waka me ngā taumahatanga o te taiao, e whakarite ana i te kaha me te roa o te piriti. I roto i ngā whare tino teitei, ka whakamahia pinepine ngā kurupae-H 12*16 ki ngā wāhi matua pērā i ngā ngongo matua me ngā pou anga, e whakarato ana i te tautoko kaha mō te hanganga katoa me te tiaki i a ia mai i ngā āhuatanga taiao pērā i te hau me te rū whenua. Hei tāpiri, he mahi nui anō hoki tā ngā kurupae-H 12*16 i roto i ngā kaupapa nui pērā i ngā turanga taputapu ahumahi nui me ngā taunga tauranga.
I roto i ngā kupu poto, he mea nui ngā kurupae-H ASTM A992, me ā rātou mahi tino pai me ngā rahi mahi rerekē, i roto i ngā kaupapa hanga maha. Me ō rātou āhuatanga ahurei, ka tutuki i ngā kurupae-H 6*12 me 12*16 ngā hiahia kanorau o ngā kaupapa maha, ka akiaki i te whanaketanga tonu o te hanga hangarau hou.
E whakaatu ana ngā tuhinga o runga ake nei i ngā āhuatanga o te ASTM A992 Waro Steel H Beam, mai i te mahi ki te tono. Mena kei te hiahia koe ki te tāpiri i ētahi atu whakatakotoranga, i ngā horopaki tono rānei, tena koa whakamōhio mai.
