He aha te meatokotoko waea
Ki te kīanga māmā noa, ko te rino porowhita he waea, arā, he mea porowhita hei hanga i tētahi porowhita, ko te hanganga me whakatika, ko te whānui he 10, iti iho rānei.
E ai ki te rahi o te diameter, arā, te matotoru, ka wehea ki ngā kāwai e whai ake nei:
Rino porowhita, pae, waea, koiri
Rino porowhita: he nui ake te diameter whakawhiti i te 8mm o te pae.
Pae: te āhua whakawhiti-wāhanga o te maitai porowhita, hexagonal, tapawhā, me ētahi atu āhua tika. I roto i te maitai kore waikura, ko te pae whānui e pā ana ki te nuinga o te maitai porowhita.
Ngā tokotoko waea: ki roto i te porowhita porowhita o te koiri porowhita, ko te diameter he 5.5 ~ 30mm. Mēnā ko te Waea anake, e pā ana ki te waea maitai, ka tukatukahia anō e te koiri i muri i te tukatuka i ngā hua maitai.
Tokotoko: he mea takai wera, he mea takai ki roto i te kōpae hei tuku i ngā hua kua oti, tae atu ki ngā porowhita, tapawhā, tapawhā hāngai, tapaono-ā-ira me ētahi atu. Nā te mea ko te nuinga o ngā porowhita, ko te nuinga o te koiri ko te koiri toko waea porowhita.
He aha te tini o ngā ingoa? Anei te whakarōpūtanga o te maitai hangahanga
He aha ngā whakarōpūtanga o te maitai hangahanga?
Ko ngā momo hua o te maitai hangahanga ka wehea whānuitia ki ētahi momo pēnei i te rino whakapūmau, te maitai porowhita, te tokotoko waea, te koiri me ētahi atu.
1, pā rakau
Ko te roa whānui o te rebar he 9m, 12m, ko te miro 9m te roa e whakamahia ana mō te hanga rori, ko te miro 12m te roa e whakamahia ana mō te hanga piriti. Ko te whānuitanga o ngā whakatakotoranga o te rebar he 6-50mm te nuinga, ā, ka taea te whakarerekē i te āhua. E ai ki te kaha, e toru ngā momo rebar: HRB335, HRB400 me HRB500.
2, maitai porowhita
E ai ki te ingoa, he rino totoka te maitai porowhita, he porowhita te wāhanga, e toru ngā momo: te huri wera, te hanga me te tō matao. He maha ngā rauemi o te rino porowhita, pērā i: 10#, 20#, 45#, Q215-235, 42CrMo, 40CrNiMo, GCr15, 3Cr2W8V, 20CrMnTi, 5CrMnMo, 304, 316, 20Cr, 40Cr, 20CrMo, 35CrMo me ētahi atu.
Ko ngā whakatakotoranga maitai porowhita hurihuri wera mō te 5.5-250 mm, 5.5-25 mm he maitai porowhita iti, he paihere ngā pae tika, e whakamahia ana hei pae whakapakari, hei pūtu me te maha o ngā wāhanga miihini; neke atu i te 25 mm te maitai porowhita, e whakamahia ana i te nuinga o te wā i roto i te hanga wāhanga miihini, i te hanga paipa maitai kore hononga rānei.
3, tokotoko waea
E toru ngā momo waea e whakamahia whānuitia ana, arā, ko te Q195, Q215, me te Q235, engari e rua anake ngā momo o te hanganga o ngā koiri maitai, ko te Q215 me te Q235 te nuinga o ngā momo, ko te whānui o te 6.5mm, ko te whānui o te 8.0mm, ko te whānui o te 10mm. I tēnei wā, ko ngā koiri nui rawa atu o Haina ka taea te whānui ki te 30mm. Hei tāpiritanga ki te whakamahi i te waea hei whakakaha mō te hanganga o te raima whakakaha maitai, ka taea hoki te whakamahi ki te waea hei kukume, hei hono kupenga ki te waea. He pai hoki te tokotoko waea mō te kukume waea me te hono kupenga.
4, tīwiri koiri
He rite te tīwiri koiri ki te waea he rite ki te taura whakapūmau kua kopikopikohia, he momo maitai mō te hanga whare. He whānuitia te whakamahinga o te taura whakapūmau i roto i ngā momo hanganga whare, ko ngā painga o te taura whakapūmau koia tēnei: ko te taura whakapūmau he 9-12 noa iho, ka taea te whakamahi i te taura whakapūmau kia rite ki te hiahia mō te hopu ā-wā.
Te whakarōpūtanga o te rebar
Ko te tikanga, e ai ki te hanganga matū, te tukanga whakaputa, te āhua hurihuri, te āhua tuku, te rahi o te diameter, me te whakamahinga o te maitai i roto i te hanganga o te whakarōpūtanga:
(1) e ai ki te āhua i hurihia
① parepare kanapa: Ko ngā parepare karaehe I (parepare maitai Q235) he mea hurihuri hei hanga porowhita kanapa, he kōpae porowhita te āhua, kāore e neke ake i te 10mm te whānui, he roa 6m ~ 12m.
② ngā pae maitai rara: e toru ngā āhua porowhita, hereni me te āhua marama-tītaha, ko te tikanga he Ⅱ, he Ⅲ te maitai hereni, ko te maitai Ⅳ te maitai hereni porowhita me te āhua marama-tītaha.
③ Waea rino (e rua ngā momo waea rino waro iti me te waea rino waro) me te aho rino.
④ pae rino miro matao hurihia: hurihia matao me te matao miro kia rite ki te āhua.
(2) e ai ki te rahi o te diameter
Waea rino (diameter 3 ~ 5mm),
Pae maitai angiangi (diameter 6~10mm),
He rino matotoru (neke atu i te 22mm te whānui).
