TL;DR — Ngā Whakaaro Matua
- Ngā pūnaha ārai mapereme tu atu ki te kawenga whakapae 0.75 kN/m mō ia IBC 1607.8.
- Kāore e taea te neke ake i te tawhiti o te papa rākau100mm te whakatuwheratanga māramahei ārai i te mauheretanga o te tamaiti.
- Ngā rahinga paerewa o te pāra: 80-120mm te whānui, 850-1,100mm te teitei i runga ake i te papa kua oti.
- Te mokowā pou i te nuinga o te wāNgā pokapū 1,200-1,800mmi runga i te whirihoranga o te rēri.
- Me whakamahi he punga matū, he hononga ā-ringa huna rānei hei tāutanga, ā, kua whakatauria kia tika te kukū me te tākai.
He pūnaha ārai te ārai māpere, kei roto ko ngā pou poutū (ngā ārai), ngā reera whakapae, me ngā hanganga hou, he mea hanga ki te kōhatu tūturu.Ka whakaratohia e ēnei huinga he parenga hinganga i ngā arawhata, i ngā taupee, me ngā ara hikoi teitei, me te whai wāhi atu ki te ataahua o te hoahoanga. Kei roto i ngā whakatakotoranga ngā tataunga hangarau hanganga, te tutuki i ngā ture hanga whare, me te whakataurite ki ngā āhuatanga o te papa.
Nā te mea he āhuatanga haumaru ngā pūnaha taupee, ko ngā momo rahunga ko te hinganga nui i raro i te kawenga taha.E whakahau ana te International Building Code (IBC) i ngā paearu mahi motuhake mō ngā pūnaha pupuri ringa me ngā pūnaha tiaki. E neke atu ana te kaha pēhi o ngā papa kōhatu i te 80 MPa engari me āta mahi hangarau kia aro atu ai ki te iti o te kaha kume me te pakarukaru o te kōhatu i te wā e pāngia ana.
He aha ngā whakaritenga kawenga hei whakahaere i te hoahoa o te taupee?
Te hoahoa hanganga ongā pūnaha papa kōhatue whai ana i ngā whakaritenga o te IBC Wāhanga 1607.8 me te ASCE 7 Upoko 4.

Ka taea e ngā papa rino te hono i ngā hononga whakarewa, i ngā hononga pūtu rānei:
- Ngā pereti turanga i honoa ki te anga maitai
- Ngā here ā-ringa (te iti rawa o ngā pūtu A325)
- Ka ārai ngā papa wehewehe i te waikura galvanic i waenga i te kōhatu me te maitai
He pēhea te awe o te āhuahanga o te Baluster ki te mahi?
Ka pā te wāhanga whakawhiti me te teitei o te papa ki te kaha hanganga me te tutuki i ngā ture.
Ngā Āhuatanga o te Diameter me te Wāhanga
Ko te whānui o ngā pārae paerewa kei waenga i te 80mm (whare noho) me te 150mm (pākihi). Ko te modulus wāhanga (S) mō ngā wāhanga porowhita he rite ki te πd³/32.Ko te pārau he 100mm te whānui, ka whakarato i te modulus wāhanga o te 98,175 mm³, ā, ka ātete ki te nekehanga piko o te 1.47 kN·m i te ahotea whakaaetia 15 MPa.
Ka whakanui ake ngā pārae whakarara (whānui ake i te turanga) i te modulus wāhanga i te wāhi ahotea nui. Ko te ōwehenga whakarara noa o te 1:12 ka whakarato i te pikinga kaha 20-30% i te turanga me te kore e whakararu i te ataahua.
Ngā Herenga Teitei
E whakahau ana te IBC 1015.2 i te teitei iti rawa o ngā kaitiaki:
- Whare Noho (R-3 te nohoanga): 900mm i runga ake i te mata tata
- Arumoni (ētahi atu wāhi noho): 1,070mm i runga ake i te mata tata
- Ngā pūmau arawhata: 860-960mm i runga ake i te ihu o te arawhata
Mā te teitei o te poupou ka nui ake te nekehanga piko i te hononga turanga.He 33% te teitei ake o te nekehanga o te pāra 1,100mm i te pāra 900mm i raro i te kawenga whakapae ōrite. Me whakamana hangarau mō ngā teitei neke atu i te 1,200mm.
He aha ngā Tikanga Tiaki hei Pupuri i te Pūmautanga o te Pāreti?
Ngā whakaritenga tiaki mōngā pūnaha papa kōhaturerekē i runga i te whakaaturanga me te rauemi.
Ko ngā whakaurunga o waho e hiahiatia ana:
- Te tirotiro ā-tau i ngā pūwāhi punga mō te waikura, te wetekina rānei
- Te hiri anō i ngā hononga turanga i ia 5-7 tau
- Te horoi ki ngā wairewa pH-kore (kaua e whakamahi i ngā wai horoi waikawa i runga i te māpere/kōhatu kōhatu)
- Te whakakapinga o te hiri hononga kua pakaru
He iti noa te pānga o te huarere ki ngā papa kōhatu; me tirotiro auau ake te māpere me te kōhatu kōhatu mō te horo o te mata.Ka tere ake te pirau o ngā kōhatu pūngoi ina rewa-tio—mēnā neke atu i te 0.5% te mimiti o te wai, e tohu ana tēnei i te hiahia kia whakakapia.
