I. Ngā Whakatakotoranga Diameter (Awhe Whakamahinga Matua) Me tino tutuki ngā whakaritenga diameter o te rebar HRB400E ki te "Pae Rino Ripiri Wera mō te Konukura Whakakaha" (GB/T 1499.2-2018). Ko te whānuitanga diameter ingoa ko 6mm-50mm, e kapi ana i te nuinga o ngā āhuatanga ahotea i roto i te hangarau. Ko ngā diameter rerekē e rite ana ki ngā whakaritenga tono rerekē, penei: Diameter iti (6mm-12mm): E whakamahia ana mō ngā wāhanga iti, ngā arai, me ngā pae tohatoha, pērā i ngā pae tohatoha papa, ngā pae here pakitara, ngā arai lintel, me ētahi atu. Ko ngā whakaritenga noa ko 6mm, 8mm, 10mm, me te 12mm; Diameter waenga (14mm-25mm): Ko te mea tino whakamahia, e tika ana mō ngā wāhanga matua e mau ana i te ahotea pērā i ngā kurupae anga, ngā pou anga, ngā mema taha pakitara kutikuti, me ngā taupoki pou. Ko ngā whakaritenga matua ko 14mm, 16mm, 18mm, 20mm, 22mm, me te 25mm; Diameter nui (28mm- 50mm): Ka whakamahia whānuitia i roto i ngā hanganga whānui, ngā wāhanga taumaha, ngā wāhanga taumaha rānei, pērā i ngā pou anga wāhanga nui, ngā kurupae matua piriti, ngā whare pupuri maitai turanga pou, me ngā whakakaha turanga taputapu nui. Ko ngā whakatakotoranga noa ko te 28mm, 32mm, 36mm, 40mm me te 50mm. II. Ngā Ahu o Waho me ngā Tawhā Ripe (Ngā Whakaritenga Me Whakahau)
He porowhita te porowhita o te taura HRB400E me ngā rara i tōna roanga. Kua wehea ngā rara ki ngā rara roa (e whakarara ana ki te tuaka o te taura) me ngā rara whakawhiti (i tētahi koki ki te tuaka). Me tutuki i ngā tawhā ngā whakaritenga e whai ake nei hei whakarite i te hononga me te mahi taunga ki te raima:
Hoahoa Ripeka Whakapae:
Koki: Me noho te koki β i waenganui i te rara whakawhiti me te tuaka rebar i waenga i te 45° me te 60°. Ina ≤ 12mm te diameter o te rebar d, ka taea te whakawhānui ake i te koki ki te 30°.
Te Mokowā: Me urutau te mokowā rara whakawhiti l ki te diameter. Hei tauira, l ≤ 12mm ina d = 6mm, l ≤ 20mm ina d = 25mm, me l ≤ 25mm ina d = 50mm. Kaua te rerekētanga o te mokowā rara whakawhiti mō te pou kotahi e neke ake i te ±10%.
Teitei: Me tutuki te teitei o te rara whakawhiti h i ngā whakaritenga kaha me te here. Hei tauira, ko te h ≥ 0.8mm ina ko te d = 10mm, me te h ≥ 0.8mm ina ko te d = 20mm. Ina ko te h ≥ 1.5mm, me te d = 40mm, ko te h ≥ 2.4mm, me te teitei tuturu i inehia kaua e iti iho i te 90% o te uara paerewa. Hoahoa Ripa Roa: Rahinga: Me rua ngā rara roa e tohatohahia ana i ia pou. Me ōrite te whānui b o te rara roa ki te diameter, hei tauira, ko te b = 2.0mm ina ko te d = 16mm, ko te b = 3.0mm ina ko te d = 32mm; Roa: Me rere te rara roa i te roanga katoa o te pou me te kore he āputa, he motumotu rānei, ā, me neke maeneene te tihi o te rara roa ki te tihi o te rara whakawhiti hei karo i te kukū o te ahotea i puta mai i ngā taha koi. Te Rerekētanga Wāhanga: Me noho te rerekētanga whānui tuturu o te parepare i roto i te ±0.4mm (hei tauira, mō te parepare he 20mm te whānui ingoa, me noho te whānui i inehia i waenga i te 19.6mm me te 20.4mm); Kaua te rerekētanga taha o te wāhanga e neke ake i te ±2%, ā, ko te porowhita (te rerekētanga i waenga i te whānui mōrahi me te whānui iti o te wāhanga) me ≤0.4mm kia rite ai te āhua o te wāhanga me te tohatoha ahotea ōrite.
