Whirihoranga Haumaru oPapa Mahi Rererangi
Hei whakarite i te haumaru o te papa hiki, he maha ngā taputapu haumaru mō te papa hiki. I tēnei rā ka kōrero tātou mō ngā taputapu haumaru ārai-hinga me ngā pana haumaru:
1. Pūrere haumaru ārai-hinga
He wāhanga nui te taputapu haumaru ārai-hinga o te papa hiki, ā, me whakawhirinaki ki tēnei hei whakakore i te tūponotanga o ngā aituā hinga o te whare herehere, me te whakarite hoki i te haumaru o ngā kainoho. Nō reira, he tino pakari te whakamātautau a te wheketere i te taputapu haumaru ārai-hinga. I mua i te wehenga atu i te wheketere, ka ine te wāhanga tirotiro ture i te taipana, ka ine i te tere matua, ka ine hoki i te pēhanga puna. Ka haere tahi ia wāhanga me tētahi pūrongo whakamātautau, ā, ka huihuia ki runga i te ararewa. Ka mahia te whakamātautau taka i raro i te kawenga kua whakatauria, ā, me taka te papa hiki e whakamahia ana i te papa hanga i ia toru marama. Me tuku hoki te taputapu haumaru ārai-hinga o te papa hiki kua tukuna mō ngā tau e rua (te rā i tukuna ai te taputapu haumaru ārai-hinga) ki te wāhanga tirotiro ture hei tirotiro me te whakamātautau, kātahi ka whakamatautauria kotahi i te tau. Tae noa ki tēnei wā, he iti noa iho ngā tāngata kua tono kia tirohia, ā, ko ētahi papa hanga kāore e mahi i te whakamātautau taka i ia toru marama, e whakaaro ana kei te pai ā rātou taputapu haumaru ārai-hinga, engari i te wā ka puta he aituā, ka pouri rātou. He aha e kore ai e whakamātautau me te tuku kia tirohia i ia wā, i runga i te pūnaha? He pai mēnā ka whakaaro pōuri te kaiwhakamahi kāore i te kino. Inaa, ko te kounga o te taputapu ārai-hinga ka taea anake te aromatawai mā te whakamātautau me te tirotiro. Kāore e taea te whakatau mēnā he pai, he kino rānei i roto i te mahi o ia rā. Mō ngā taputapu ārai-hinga kua roa e whakamahia ana, me tuku wawe atu ki te tirotiro me te auau. He pai ngā whakamātautau, ā, mā te mōhio ki te aha e taea ai te ārai i ngā aituā kino i mua i te puta. (Ka taea te tuku i te kitenga o ngā taputapu ārai-hinga ki: Changsha National Construction Machinery Quality Inspection Center, Shanghai Academy of Construction Sciences, Shanghai Jiaotong University, me ētahi atu.)
2. Pātene haumaru
Ko ngā pana haumaru o te ararewa kua hangaia kia rite ki ngā hiahia haumaru, tae atu ki te rohe tatau taiapa, te rohe tatau whare herehere, te rohe tatau o runga, te pana rohe, te pana rohe o runga me raro, te pana tiaki taura ārai-whati taumaha, me ētahi atu. I ētahi wāhi hangahanga, hei karo i ngā raruraru, ka whakakorehia ā-ringa ētahi pana rohe, ka porowhitahia, ka pakaru rānei, ā, kāore e whakatikahia i te wā tika, he rite tonu ki te whakakore i ēnei rārangi tiaki haumaru me te whakato i ngā aituā huna. Hei tauira: Me utaina te whare iri ki ngā mea roa, ā, kāore e taea te uru ki roto te whare iri, me toro atu ki waho o te whare iri, ā, ka whakakorehia te rohe tatau, te rohe tatau o runga rānei. Mēnā kāore i tino tika, kāore rānei i oti ngā whare haumaru kua whakahuatia i runga ake nei, ka mau tonu te tangata me te kawenga. He kata noa iho tēnei momo mahi ture kore ki ngā oranga tangata. Hei karo i ngā tūponotanga huna o ngā aituā, e tumanakohia ana ka whakapakari ngā kaiārahi o te wāhanga i te whakahaere, ka tono kia tiakina te papa hiki, ā, me tirotiro tonu ngā kaiwhakahaere i te haumaru me te pono o ngā pana haumaru hei ārai i ngā aituā.
Hei whakarite i te haumaru o te papa hiki, he maha ngā taputapu haumaru mō te papa hiki. I tēnei rā ka kōrero tātou mō te whakakapinga o ngā taputapu me ngā whata, te tere kawenga rangitahi me te ārai:
3. Te mau me te whakakapi i ngā taputapu me ngā whata
I te wā e hangaia ana te papa hanga, he kino te taiao mahi, ā, kāore e taea te whakakore i te sima, te moata, me te puehu. Kei te huri ngā taputapu me ngā whata tetahi ki tetahi, ā, kei te whakamahia tonu ngā niho i muri i te whakakoi. Me aro nui ki tēnei. E mōhio ana tātou katoa, me rite te āhua o te niho ki te kurupae cantilever. Ina pakaru ki tētahi rahi, me whakakapi te taputapu (te whata rānei). Kia pēhea te nui me mutu taku whakamahi, ka whakakapi ki tētahi mea hou? Ka taea te ine ki te maikoromita noa 25-50mm. Ina pakaru te roa o te noa noa o te taputapu mai i te 37.1mm ki raro iho i te 35.1mm (2 niho), me whakakapi he taputapu hou. Ina pakaru te whata, ka inehia e te caliper matotoru niho. Ina 8mm te teitei o te aho, ka pakaru te matotoru o te niho mai i te 12.56mm ki raro iho i te 10.6mm. Me whakakapi te whata. Heoi, he maha ngā taputapu "niho tawhito" kei te papa hanga. Kei te mahi tonu te papa i te wā e tika ana kia whakamahia. Hei take haumaru, me whakakapi ngā wāhanga hou.
4. Te tere kawenga rangitahi
He maha ngā wā e whakahaerehia ana ngā ararewa i te papa hanga, ā, he nui te tere whakamahinga, engari me whai whakaaro ki te raruraru o te pūnaha mahi wā poto o te motuka, arā, te raruraru o te tere kawenga wā poto (e kiia ana ko te tere roa o te kawenga), e tautuhia ana ko FC=te wā huringa mahi/te Wā kawenga × 100%, ko te wā huringa mahi ko te wā kawenga me te wā whakatā. Ko te papa hiki i ētahi papa hanga ka riihitia e te kamupene riihi, ā, e hiahia tonu ana kia whakamahia katoatia. Heoi, ko te tere kawenga wā poto o te motuka (FC=40%, 25 rānei%) kāore i arohia. He aha te take kāore te motuka e whakaputa wera? Kei te whakamahia tonu ētahi ahakoa he haunga wera, he mahi tino rerekē. Mena he iti te hinu whakahinuhinu o te pūnaha tuku ararewa, he nui rawa rānei te ātete oma, he taumaha rawa, he maha rānei te tīmatanga, he kāreti iti e tōia ana e te hōiho. Nō reira, me mārama ia taraiwa i te papa hanga ki te ariā o te huringa mahi, me mahi i runga i ngā ture pūtaiao. He mea hanga tēnei momo motuka mō te mahi wā poto.
5. Pūpare
Ko te rārangi parepare whakamutunga mō te haumaru o te papa hiki o te ararewa, tuatahi, me tāuta, tuarua, me whai kaha, ka taea te tu atu i te pānga o te kawenga kua whakaritea o te ararewa, ā, me whai tūranga parepare. Ā, inaianei he maha ngā papa hangahanga, ahakoa kua whakatūria ētahi, engari kāore i te nui hei mahi parepare, kāore he parepare i te papa hangahanga, he tino hē tēnei, ko taku tumanako ka aro te kaiwhakamahi ki te tirotiro, ā, kaua e whakaiti i tēnei rārangi parepare whakamutunga.
