Ngā Pūrongo - Ngā Kurupae-H o te Whare Hanga: He Arataki Matua e Whakakaha ana i te Whanaketanga Ahumahi Kounga Teitei

kurupae H piauau i roto i ngā kaihanga Haina

Nō nā tata nei, nā te whanaketanga tonu o te noho tāone me te tere haere o ngā kaupapa hanganga matua, kua piki ake te hiahia mō te maitai hangahanga mahi teitei. I roto i ēnei,H-hiku, hei wāhanga matua mō te pikaunga kawenga i roto i ngā kaupapa hanga, kua noho hei kaupapa matua mō te whakatairanga i te whanaketanga kounga teitei o te umanga hanga, nā ōna āhuatanga miihini tino pai me ōna whakamahinga whānui e ārahi ana i tētahi au hou i te mākete.

I roto i tētahi kaupapa whare noho teitei nui i te rawhiti o Haina, he puranga oHEB 150 Ngā hihi-Hkua whakauruhia ki roto i te hanganga matua. Hei tauira kurupae-H paerewa noa o Ūropi, e paingia ana te HEB 150 e ngā wae hanga mō tōna hoahoa wāhanga taurite, tōna ātete piko kaha me tōna kaha pikau kawenga pumau. "Ki te whakaritea ki ngā wāhanga maitai tuku iho, ka taea e te HEB 150 te whakaiti i te maha o ngā hononga huihuinga mā te 30% i roto i te tukanga hanga, ka whakapotohia te wā hanga me te whakarite i te haumaru hanganga," te kī a te miihini matua o te kaupapa. Ehara i te mea ka manatokohia e tēnei tono te uara mahi o ngā hua kurupae-H paerewa i roto i te hanganga whare noho, engari ka whakaratohia hoki he tohutoro mō te whakatairanga i ngā hanganga maitai paerewa i roto i te umanga.

Ahakoa e whakamahia whānuitia ana ngā tauira paerewa,ngā hua hihi-H mahi teiteie tohuhia ana eASTM A572-50 H kurupaeKei te tere ake hoki tā rātou urunga ki ngā kaupapa matua. E mārama ana he tino pakari ngā kurupae ASTM A572-50 H i te pāmahana iti me te ātete ki te waikura, ā, ka taea e ō rātou kaha whakaputa te eke ki te neke atu i te 345MPa, he mea tino pai mō ngā awheawhe whānui, ngā piriti huarahi me ētahi atu kaupapa he nui ngā whakaritenga hanganga. I tēnei wā, i roto i te hanganga o te piriti whakawhiti-awa i te Tonga o Haina, kua whakamahia ngā kurupae ASTM A572-50 H i roto i te hanganga whariki matua, e whakaoti pai ana i te raruraru o te pēhanga kawe i raro i ngā āhuatanga huarere uaua, me te whakarite i te roa o te ora ratonga o te piriti.

Hei tāpiritanga,Ngā kurupae whānui ASTM A572-50, hei hua i ahu mai i te H-beam, kua whakawhānui ake i te whānuitanga o te whakamahinga o te H-beam i roto i te umanga hanga. Nā te whānui o te flange, ka taea e tēnei momo kurupae te tohatoha pai ake i te kawenga me te whakapai ake i te pumau o te hanganga. Kua whānuitia te whakamahinga i roto i te hanganga o ngā whare arumoni nui me ngā tipu ahumahi i ngā tau tata nei. I kī tetahi tangata e whakahaere ana i tētahi umanga whakaputa maitai: "I te haurua tuatahi o tēnei tau, i piki ake te nui o te ota o ngā kurupae flange whānui ASTM A572-50 mā te 40% i ia tau, ā, kua kaweakehia hoki ngā hua ki ngā mākete o te Tonga-Rawhiti o Āhia, ka noho hei pūwāhi tipu hou mō tā mātou pakihi kaweake."

I kī mai ngā kaitōrangapū o te umanga, ko te tere o te whanaketanga o te H-beam mō te hanga whare, ehara i te mea e whakaatu ana i te whakapai ake i te hiahia o te umanga hanga whare mō te maitai kounga teitei, engari e whakatairanga ana hoki i te auahatanga hangarau o te umanga maitai. I te heke mai, me te whakapai tonu i ngā paerewa ā-motu mō ngā whare matomato me te hanganga waro-iti, ka nui ake te mahi a ngā hua H-beam me te mahi teitei ake, te tiaki taiao ake me te kanorau ake, ā, ka nui ake te mahi hei whakatairanga i te whanaketanga kounga teitei o te umanga hanga whare.
