Te whakamātautau i ngā pātaka hāngā kōrero mō ngā rōpū nui
He aha ngā take e whiriwhiri ana ngā rākau nui i ngā pātaka kōrero kōpū
Te Whakauru i ngā Āhuatanga o te Whakamātautau me ngā Whakamātautau o te Toa i ngā Taiao o te Rākau
Ko ngā kamupani rahi āhua noa nei e whai ana i ngā pātaka kōrero kōpū kia rere kē i te āhua, engari i tēnei wā he nui ngā take o te whai i aua pātaka kōrero kōpū i te hāngai tonu ki ngā mahi. Ko ngā pātaka kōrero kōpū ā-hāpaitanga nei e tātai ana i te whare i whakamāmātia ai, ā, e whakaatu ana i te āhua o te kamupani i runga i ngā mea pērā i te mātātoko, te whakamātautau, te āhua o te kōpū, me ngā āhua o ngā tapa. I rongo mai a Building Design + Construction i tēnei tau i te 2023, ko ngā kaiwhakamārama āhua noa nei e whai ana i te whakamātātutanga o ngā āhua katoa i ngā tārua whakamārama mō ngā tārua tauhokohoko i tēnei wā. Arā, ko te whakamāhinga ake i ngā āhua ā-hāpaitanga he whakamāhinga i tēnei wā i tēnei mahi pūmau—ko te neke i waenganui i ngā pātaka—kia āhua pai hoki. Kāore ngā whakamāhinga ā-mātātoko e tuku ana i tēnei āhua o te whakamāhinga, kia taea ai e ngā kamupani te whiwhi i ngā mea e hiahiatia ana mō ō rātou wāhi.
- Ngā rāringa ā-taumata me ngā whakamātautau o ngā tapa e whakakaha ana i te reo ā-ahurea o te kamupani
- Te whakamāhinga o te rere o ngā wāhi i tēnei wā i ngā here ā-pūnaha kē
- Ngā whirihanga kōpū o te wāhi e whakamāngai ana i te āhua taiao
Te huringa mai i ngā whakamātautau pāpātanga ki ngā whakamātautau ā-tāngata: ngā kaha e āki ana i te haumaru, i te whaihua, me te whakamāngai i ngā wāhi
Kei te piki haere te tono a ngā pakihi ki ngā arawhata whakarewa ritenga mō ngā take matua e toru: ngā ture haumaru, ngā whāinga hanga taiao, me te hiahia ki te whakanui i te wāhi papa iti. Mēnā me whai ngā kamupene i ngā waehere IBC me ASTM tino tika, otirā i ngā wāhi e nui ana te waka hiko, ka hiahia rātou ki ngā arawhata motuhake e taea ai te whakahaere i ngā kawenga taumaha rerekē, me te whakarato i ngā ara rere tika i ngā wā ohorere. Kei te akiaki ngā kaupapa matomato i ngā kamupene ki te whiriwhiri i ngā momo maitai motuhake. Kei te whakamahi ngā kaiwhakanao nui i te maitai e neke atu i te 90% te ihirangi tāruatia ana e ai ki te Metal Construction News i te tau kua hipa. Ko te painga nui rawa pea ko te penapena wāhi. Ka taea e ngā arawhata hanga-a-taputapu te whakaora i te 40% o te wāhi papa i whakaritea ki ngā tauira paerewa. Ko ētahi kamupene e whiriwhiri ana i ngā hoahoa porohita, i ētahi atu e haere ana ki ngā konumohe kōtuitui ina nui ake te tikanga o te whakawhānui ki runga ake i te horahanga ki runga i te taha o te taha, nā te utu nui o te whare. Ko te mea i whakamahia hei hanganga mahi noa iho, kei te noho hei whakatau haumi rautaki mō ngā whakahaere maha.
Te Whai Hāhi: Te Tūpono, te Whakamāmātanga i ngā Ture, me ngā Hua o te Whakamāhi i te Nui o ngā Kiritaki
Te Whakamātau i ngā Whāinga o te IBC, o te ASTM, me ngā Whāinga o LEED i wāhi kē
I te whakamahi i ngā pātaka kōrero kōpū kōpū i ngā whare herehere, he mea tino hirahira te whai i ngā tātai o te ao. Ko ngā ture e kōrero ana i tēnei ko ngā ture IBC, ASTM, me ngā āhuatanga whai hua o LEED. Mēnā kāore e whai i ēnei ture, ka rere mai ngā raru pūmātao me ngā whakawātā hauāhi e tata ana ki te $740,000 i ia wā, arā i ngā raraunga o te tau 2023 mai i te ao pakihi. Kātoa ngā kōpū kōpū e whakamānaitia ana e ngā whare whakamātautau takitahi hei whakamātautau i ngā mea pērā i te uara o te taumaha e whai ai, tana pānga ki te ahi, me tana whai hua hei whakamāreke i ngā hāngā i ngā wāhi maha o ngā papa. Hei tauira, ngā papa o ngā pātaka. Ko ngā papa e whai ana i ngā whakamārama o ASTM C1028 me te tauwhāinga o te pānga o te hāngā (static coefficient of friction) o te 0.5, ka whakamāreke i ngā huarahi o ngā huarahi o te hāngā i ngā wāhi wetewete e 40% tonu. Ka taea te whiwhi i ngā tohu o LEED mā te whakamahi i te kōpū kōpū e toru tekau ngā rākau i te kōpū kōpū i te kōpū kōpū, me te whakamārama kia kaha ake i te 90% o ngā kōpū kōpū hei whakamātautau i ngā wā kei muri. Ko tēnei ara hei tautoko i ngā kamupene kia tūhono ki ō rātou whāinga whai hua, pāpori, me ngā whakamāramatanga, ā, kia whakamāmā hoki i ngā kaimahi.
Ngā Rautaki Mātātoko: Te Hīni, te Hīni Kāpā, me ngā Pūnaha Tāwhai Hāwhe mō te Wā Ora o ngā tau 75+
Ko te whirihanga i ngā mātātoko e whāia ana he pānga tūmatua ki ngā utu o te wā o te ora me te tāwhai:
| Rauemi | Anuanutanga Matua | Te Whakamātautau i te Wā Ora |
|---|---|---|
| Manga tangata | Te whai hua i ngā utu + te whai hua o te whakauru | ngā tau 50+ (i tēnei āhua o ngā kōpae) |
| Kowiri tira | Te whakawātea i te riri + te iti i ngā mahi whakamātua | ngā tau 75+ |
| Tāwhai Hāwhe | Te iti i te tāmira + te whai hua o te whakamātautau i ngā riri whenua | ngā tau 60+ |
Ko te maitai kua whakaranu weratia ki te whakakikorua konutea, 600 karamu ia mita tapawha, e tuku ana i te 75 tau o te tiaki ki te waikura ahakoa i roto i ngā taiao tino uaua. Mo ngā wāhi e tata ana ki te wai tote, he mahi whakamiharo te maitai kore waikura 316L ki te kino o te waikura, e whakaiti ana i ngā utu tiaki kia āhua haurua i te mea e whakaritea ana ki ngā konutea noa. I te wa e hanga ana i ngā wāhi e kaha ana ki te ngaru, he maha ngā wā e whakakotahi ana ngā kaipūkaha i ngā mea mā te whakakotahi i ngā wāhanga konumohe māmā me ngā wāhanga maitai kaha ake. Mā tēnei huarahi ranu e whakaiti i ngā ngaru e kotahi me te hawhe te pai ake i ngā tikanga tuku iho. I mua i te putanga o ēnei rauemi ki te mākete, ka haere rātou i roto i ngā whakamātautau tino uaua i reira ka tere ake te wā ki te whakaata i te rau tau o te kakahu me te roimata o te ao tūturu. Ka āwhina ēnei whakamātautau ki te whakamatau mēnā ka tutuki ngā hua i aua paerewa ISO 15686 nui mō te roa o te roa o te wā.
Te whakataurite i ngā whirihoranga matua: Helical, Double Stringer, me Mono Stringer mō te tauine umanga
Te Whaiwhaitanga o te Tāruatanga, te Whakamāhua o te Whānui i waenganui i ngā tau, me te Whakamāmā o te Whakamāhi i ngā tārua
Ko ngā rākau nui e whai ana i ngā āhuatanga o ngā pātaka kia whakamāhua ai ngā mahinga o te tārua i te wā anō hoki e whai ana i ngā āhuatanga o ngā whare pūmau. Ko ngā āhuatanga toru matua e tū ana i ngā tārua o te pakihi:
| Whirihoranga | Te Whaiwhaitanga o te Tāruatanga | Te Whakamāhua o te Whānui i waenganui i ngā tau | Te Whakamāmā o te Whakamāhi i ngā tārua |
|---|---|---|---|
| Helical | Te wehenga o ngā uta mātua | Te whakamāhua iti o te āhua āhua | He hāngā tonu te hāngā o ngā wāhi |
| Tārua Pātata | Te tautoko whānui o te tārua | Whakamāhinga i te whakamāhinga anō i te rere | Te whānanga tūpuna kia piki ake |
| Tātai kotahi | Te whakamāhinga iti o ngā kōpae | Te whakamāhinga āwhina kia rere kē | Ngā pūnaha tautoko kua whakauru |
Ko ngā pātaka hāngā hāngā e whakamāhinga ana i te whakamāhinga o te wāhi i ngā wāhi iti—e tino pai ana mō ngā pātaka hāngā hāngā rorohiko—engari he rerekē ngā hāngā mai i te papa ki te papa.
Ko ngā whakamāhinga o ngā tātai rua e whakamāhinga ana i te tātai o te tātai kia tino mātua mō ngā wāhi e whakamāhinga ana; ko ngā tātai rua e whakamāhinga ana i ngā whakamāhinga i te wā o te whakamāhinga.
Ko ngā whakamāhinga o ngā tātai kotahi e whakamāhinga ana i te tātai o te tātai kia iti ake i te 40%, e whakamāhinga ana i te whakauru kia rere kē i ngā pūnaha whakamāhinga o ngā whare i ngā papa maha.
Me whiriwhiri ngā rōpū hāpai ngā rākau hāere mai i te kōpū i runga i ēnei tohu whakamātautau matua: te rākau hāere mai i te whānui, te rākau hāere mai i ngā wāhi e tāwhai ana i te wāhi, te rākau hāere mai i ngā wāhi pāwhara hei whakamātautau i ngā wāhi mahinga, me te rākau hāere mai i te wāhi kotahi hei whakamātautau i te huruhuru o ngā kāpae tāpoi.
Te Uara Tōtahi o te Whakamahi i ngā Rākau Hāere Mai i te Kōpū i ngā Tāpoi Nui
Mā te titiro ki te Utu Katoa o te Kaihoko (TCO) mō ngā arawhata whakarewa ritenga e āwhina ana ki te whakamārama he aha i arotahi ai ngā pakihi maha ki te uara ora, kaua ki te utu i mua. Ae ra, he nui ake te utu o te hanga i ēnei arawhata i te tīmatanga, i te nuinga o te wā 25 ki te 40 ōrau atu i ngā kōwhiringa o mua, engari ka kitea e ngā kamupene he iti ake te moni i te wā roa nā te mea he roa ake te roa o ēnei hanganga, he pai ake hoki te mahi i ia rā E whakaatu ana ngā rangahau puta noa i ngā ahumahi rerekē e pupuri ana ngā arawhata maitai kounga teitei i te 95% o tō rātou kaha ahakoa i muri i te ono tekau tau, ko te tikanga ko te haurua o ngā utu whakakapi ina whakaritea ki ngā taahiraa raima. Ko te tikanga, ko te tiaki e haere ana i te 1% o te utu taketake ia tau, he iti iho i te 2 ki te 4% e hiahiatia ana mo etahi atu rauemi. Ā, ka whakaitihia e ngā hoahoa hou te utu pūngao e 10 ki te 20%. Ka whai hua hoki ngā pakihi i te karo i ngā whakahoutanga utu nui i muri mai i te mea ka taea te whakarite i ēnei arawhata ki ngā hiahia wāhi hurihuri, me te kore e pakaru te pēke, ka whakaora i te 40% i runga i ngā utu whakahoutanga. I te titiro ki ngā kaupapa nunui, ka huri tēnei huarahi whānui i te mea i mua he mea tika hei hanga whare ki tētahi mea e whakanui ana i te uara o ngā rawa i te wā, e āwhina ana i ngā kamupene ki te whakatau pūtea pai ake mō ngā tau kei mua.
