Wahanga o te Kauwhata Kaupapa Tūhi UL

Ki te mea e whakahoahoa ana i ngā kaka kiore, ko te rauanga tōngata te kaiwhakato kei roto i te wharekura o Amerika, ā, ko ōna āhuatanga o te maha kaha, te utu iti me te wāhanga tae noa iho ka whakanui i a ia i ngā whare mahi, ngā whare pūmau me ngā whare tuhituhinga. Ko te nāianei he whakamārama matihiko i ngā āhuatanga nui o te rauanga tōngata kiore kiore o Amerika i runga i ngā tūmomo riro, whakapapa, āhuatanga ahi, wāhanga tae noa iho, me ngā huringa tohu.

1. Riro me ngā paearu hanga

(1) Tīmatatanga o te tōngata

Kiriwhara hēneti (ASTM A1008): Pātiki kuaea, matawhāiti tino pai mo ngā rauanga tōngata pai.

Kiri aha whakawhiti uru (ASTM A36) : he iti i te utu, engari me whai i tētahi kaupapa whakarite rākau anō hei whakamahana (pērā ko te galvanizing rānei ko te pūtake).

Aha kairere (ASTM A653) : e āheinga ana ki te rūstī, e tika ana mō ngā wāhi waiwai (hei tauira, ngā wharekaupapa, ngā wāhi tai).

(2) Tauwhiro paetaki

Paetaka wāhi tūrua: 16-18 taurima (1.2mm~1.5mm)

Paetaka tūrua hiranga ahi nui (2-3 waehora) : 14 taurima (1.6mm~2.0mm) hei whakatū tonu i te āhua kore whakapae.

Pūtanga nui:

Nga kauwhata kapa toa o te tirohanga Amerika e whai ana i te 16 taumata aroaro maero, ina whakaarohia te rangatira me te utu.

Whakapae kaupapa huka iti nui (hei tauira, 3 waehora) Ko te kauwhata kapa hei whakāwheawe raweke ranei ko te roanga i waenganui hei matua huka iti (hei tauira, wana rorohiko).

2. Nga horopaki whirinaki

Ko te hanga whirinaki o nga kauwhata kapa toa ma te tirohanga Amerika kei te whai take i te mahi huka, i te whakatakoto, me te whakapiri, e whakarite ana ki nga momo nei:

(1) Whakarōpū i te mīhini o te pūtahi

Mīhini Matua Ohaoha āhuatanga kāore i te whakamahia

Pūtahi Tahi - e tika ana mō ngā wāhi tūaruhe tahi

- Wāhanga iti, utu iti, ko te pouaka ahi nēhi (nākai ki te tari, te ara paepae)

Pūtahi Rua - Whakamahia mō ngā pūtahi whakatuwhera

- Whakamana i ngā kaiwhakaruruhau o ngā rua pouaka i te wa e piri ana, he pouaka ngenge rahi (pātengareo, whare mahi)

(2) Whakarōpū hei whakaaetanga i te tikanga tūranga

Nga taumata o te momo He pai ki te kāinga

Pouaruhe - Whakauru i te wā e pouri ana te koneti

- Te māhoratanga tino pai o ngā tūrangi koneti

Pūkaha Whakauru - tirohia ngā rau parirau mīhini

- E whai ana i te āhuatanga o ngā kāinga poraka ki ngā pūnaha totohi me ngā pūnaha wāhi iti i hangaia

Pūkaha Tautohe - He whiwhi i te tautohe ±1/2" i runga i te roa

- E pai ana ki ngā pūnaha kore whai tikanga me ngā pūnaha e rerekē ana i ngā tūranga pūnaha

Pūtanga nui:

Me whakaaetia te pūkaha kura e rua nō te kura; kāore ia i tae atu ki te tautuhinga UL i te hiahia kia noho.

Te wā i waenganui o te whakapiri pūtango kē ki roto i te rauanga tīhaha kua whakaheke i 12" (me whai i te huringa e hiahiatia ana e te NFPA 80) hei whakamana i te mea kaore e pūnaha ana i te wā o te ahi.

3. Te mahi ahi me te tohu

(1) Te tae ahi e whakaaetia ana

Ko te tae ahi o te rauanga tīhaha kōwhaiwaihei e rahi atu rānei, e ōrite rānei i te pūtango (hei tauira, he pūtanga ahi 1.5 awa he mea hiahia ki te rauanga ahi 1.5 awa).

Tae ahi ahi matua o te ture U.S:

20 minutes (Tahanga C) : Wāhi iti te uiui (pērā i ngā whare rori rāpoi)

45 minutes ki te 1.5 hours (Rōpū B) : Whare whai utu, kōmuri

3 hours (Tahanga A) : Wāhi nui te uiui (hei tauira, ngā whare āpure, ngā paepae poutū)

(2) Ngā paihēnga tohu matua

UL 10B: Paihēnga mō te whakamatau whawhai ahi me te whawhai huia o ngā para tūpuke (Whawhai ahi + Whawhai huia matatika)

UL 10C: Whakamātau Ahi Kaha mō ngā pa kaiwhakarite pūtango (Tākaro hau ahi ahi)

NFPA 80: Tauarahi mō te Tūhono o ngā tūrangi pūtango (tauranga whakapikia, ngā ture whakaaetanga)

Pūtanga nui:

Nga pa tūrangi āniwaniwa me whakamātau i te UL 10B/10C, me tohu pūnuitia ki runga i te nūmera tohu o te UL.

Whakarite ahi matatika (≥90 min) Me ūngia te pa tūrangi i roto i te kōpaki ahi kore rānei, he paraerae ahi rānei.

4. Ngā ture mō te tūhono me te whakapēhi

(1) Pūnaha Whakauru (NFPA 80)

Tauanga taumanu: ≤12 inches (30cm), kia tae whakamuri ai te ahi ki te kore e hāngai ana.

Rahi i waenganui i te papa waka me te toka: ≤1⁄8", i whakapiri mai i te hara kai ahi.

Pū kawhe: e āhei ana ki ngā wā hāpai urupa (pēnei i te whetūkai).

(2) Rōpū Whakapī

Umu whakapakari: whanaketia e te uru ki te rongo i te huringa (tirohia e te ture UL 1784).

Umu kohu: Kia whakamau ai i te kohu hei whakaaturanga (whakamatauria e te whiuwhiu hā o te ASTM E283).

Pūtanga nui:

Kāore ngā paepae wāhi hei whakaae mai i te whakaaetanga!

Ngaru paepae mīhini ka whakarite tonu ki ngā pūtiwai ahi 3/4" mō te whakamana i te rōpū ture.

5. Ngā whakamahi me ngā tohutohu paihikara

(1) Ngā wāhanga whakamahi tipika

Ngā whare hanga kaiwhakahoromia (whare tūranga, pūtake whakapā) : 45 minuti ki te 1.5 waehora i raro i te rāngai maīre + peita hokohoko

Ngā whare wheako ā-motu (pūtaka tono, ngā whare mahi) : 3 waehora i raro i te rāngai maīre + peita hokohoko rua + tohu whakapae

Ngā wāhi haumanu ā-iwi (paepae, rōpu whakahaere) : rāngai maīre mōhiohia mō 2-3 waehora

(2) Ngā uiui mō te māramatanga

Whakamātau i te tūranga ahi (ki te pātai whakaaturanga rēhita rānei ki te Ture Haumanu o NFPA 101).

Tīpakohia te hanga kauwhata (notched pikinga tuatahi/tuawhā, heke noa/whakatika ārai).

Tirohia te momo takuta (koneti, tapuae poutama, takuta whatitiri).

Pānga atu (whakahoki i te kawe, tiwhikete korahi, kupu whakarite rākeke)
