Ina hikoi koe ki tētahi papa hangahanga, ki tētahi toa hanga rino rānei o te rohe, ka kite koe ahakoa he rau ngā momo kōtaha rino pea, he torutoru noa ihoWāhanga Pokapū Tapawhā (RHS)Ko ngā rahi te mea e hiki ai te taumaha. Ehara ēnei i te mea he ine matapōkere noa iho; ko ngā "wāhi pai" ēnei o te hangarau—e tuku ana i te taurite pai rawa atu o te taumaha, te utu, me te kaha.
Mena kei te whakamahere koe i tētahi hanganga, kei te rapu rauemi rānei, anei tētahi tirohanga ki ngā rahi RHS ka tūtaki koe me pēhea te whakamahi i aua rahi i te ao tūturu.
Ngā Rahi "O Ia Rā": 80×40mm me 100×50mm
Me i whai tautuhinga "taunoa" mō ngā anga rino, koinei te tautuhinga. I ngā wāhi maha o te ao, ko te 80×40 me te 100×50 ngā mea tuatahi ka tangohia e te kaiwhakarato mai i te whatanga nā te mea ka whakahaerehia e rātou te nuinga o ngā mahi hanganga māmā ki te rahi.
Ko te 80×40mm e mahi ana:Whakaarohia te wā whakamutunga i kite ai koe i tētahi taiapa whakarewa hou, i tētahi kēti pāka, i te whatanga o roto rānei i roto i tētahi waka tuku taonga. He rongonui tēnei rahi nā te mea he ngāwari ki te whakahaere—ka taea e tētahi kaihanga kotahi te neke i tētahi roa e 6 mita te roa me te kore e hiahiatia he kereini, he mea tino pai mōngā kēti noho, ngā wakatō māmā, me ngā reera o runga o te tuanui.
Te nekehanga 100×50mm:Ina neke koe ki te 100×50, ko te tikanga he "kawe-taumaha" te mea e kōrerohia ana i roto i te tikanga arumoni. Ka kitea ēnei heingā purlini roto i ngā whare putunga iti, i te anga matua rānei mōngā rarangi papa rāNā te mea he rua te hohonutanga o tōna whānui, he tino māmā noa iho te matapae mā ngā kaihangarau ki te tatau i te nui o tōna hurihanga i raro i te hukarere nui, i te hau nui rānei.
Ngā Rangatira Motuhake: 200×500mm me 60×500m
Kia tae koe ki te whānuitanga hohonu 500mm, ehara i te mea he anga anake tāu e hanga ana; engari he tohu whenua anō hoki. Ko ēnei rahi ka "tonohia e te kaupapa" kaua e puritia hei taonga puehu.Te 200×500mm (Te Mīhini Hiki Taumaha):He wāhanga tino uaua tēnei. Ka kite koe i ēnei i roto ingā pokapū kawe waka, ngā whare ahumahi nunui rānei.Nā te nui o tōna rōrahi o roto, ka whakamahia pinepinetia hei "pou whakahiato." Ka tū ake ngā kaihanga, ka ringihia he raima kaha ki waenganui, ā, kātahi ka puta he pou ka taea te tautoko i tētahi whare putunga maha-papa, engari he angiangi tonu ki te whakataurite ki tētahi pou raima nui.
Te 60×500mm (Te Kōwhiringa a te Kaihoahoa):He āhua whakamīharo, he kikokore tēnei. He rite tōna āhua ki tētahi tara rino nunui. Ka kite koe i tēnei i te taha o waho ongā whare tari papai, ngā taunga rererangi rānei.E whakamahia ana mō te "pārai ārai". Ko te hohonutanga 500mm hei ārai i te pupuhi mai o te pakitara karāhe i te wā o te tupuhi, engari he angiangi rawa te whānui 60mm, kāore e ārai i te tirohanga a te hunga i roto. He whakakotahitanga tino pai o te "uaua" me te "mārama".
Te Rino "Ngā Taipitopito": He RHS Rahi-Iti (hei tauira, 40×20mm)
Kāore e hiahiatia ana kia mau te tuanui i ngā mea katoa. I ētahi wā, me whai taha ma, tika hoki koe, e kore e piko pērā i te rakau.
Te wāhi e tika ana:Koinei te rohe ongā kaihoahoa taonga me ngā kaiwhakatakoto taonga.Ki te kite koe i tētahi anga tēpu "iti rawa" i roto i tētahi tari hangarau, i tētahi whata kakahu rānei i tētahi toa hokohoko i te tiriti matua, he 40×20mm te rahi o te RHS.paipa angiangi(1.6mm ki te 2.0mm), arā, he māmā noa te whakarewa me te mīhini whakarewa MIG paerewa, ā, he tino ataahua te paninga paura.
He aha i toa ai ngā wāhanga "kati"
He pātai noa iho tēnei:He aha i whakamahia ai he ngongo tapawhā rite (RHS) hei utu mō te I-beam paerewa, teHongere-C?
Ko te whakautu i te nuinga o te wā ka ahu mai kiTe Hurihuri (Te Takahuri).Ki te tangohia e koe he hongere-C ka whakatakotoria he taumaha ki tetahi taha, ka hiahia ia ki te takahuri pērā i te nūru. He porowhita kati te RHS; e kino ana ki te takahuri. Nā tēnei ka nui ake te haumaru mō ngā hanganga "kore taurite", pērā i te taupee cantilevered, i te tohu rānei e piri mai ana i tētahi whare. Hei tāpiri, kāore he "ngutu" he "pōke" rānei mō te wai me ngā paru manu ki roto, ka tino whakaroa i te waikura.
He Tuhipoka mō ngā "Pepa" (Ngā Māka me ngā Paerewa)
Ahakoa he mea nui te rahi, he mea nui anō hoki te "DNA" o te maitai. E rua ngā kupu matua ka rangona e koe i te nuinga o te wā:
S235 vs. S355:Whakaarohia te S235 hei "paerewa" me te S355 hei "whakamātautau tino pai." Mena kei te hanga koe i tētahi whare iti i muri i te kāinga, he pai te S235. Mena kei te hanga koe i tētahi piriti, i tētahi mea rānei ka pāngia e ngā hau kaha, me whiriwhiri koe i te S355.
Pirau vs. Mangu:Ki te hunaia te maitai i roto i te pakitara, he iti ake te utu mō te maitai "Mangu" (kua pania ki te hinu). Ki te mea kei waho, me "Hot-DIP Galvanized" te mea e hiahiatia ana. Ka āhua hiriwa, ā, he paku pīataata, engari e kore e waikura mō te toru tekau tau.
