Te Take Ko Ngā Kupenga Rebar Pākari He Mea Matua Horopaki mō Te Pakanga O Te Tū
Ko ngā koupene pīra rebar e whakakapi ana i ērā hononga tuarā hauorahia e hanga ana i ngā hononga mekanikara kaha e pupuri ana i ngā hanganga e taea ai te nui o ngā waeke e neke ana mā ngā pou, ngā tahumaero, me ngā pūpahi ōkiko anō hoki. Ina tū arotata ngā rebar, e hui maroke ana ngā puinga tokihae ka nui ake te uaua ki te tuku waeke tika. Ko te kōrero pai he mea e taea e ēnei kono pīra te whakahaere i te nuinga o te 100% o te rebar taketake e āhua ana ki ngā tāka mōhiotia pērā i te ACI 318 me te ISO 15835. Mō ngā whare e noho ana i ngā wāhi e noho ana ngā rū whenua, he nui tēnei nā te āhuatanga maroke o ēnei koupene e āwhina ana i te koha i ngā ngaru rū. Kātahi ka poporoa ngā hononga tuarā e rite ana i ērā kaha, tētahi mea e kore e hiahia kē atu ina ko te haumātao te take.
Ko ngā kōpae e pai ake i te whakarite haumātaunga, ā, ko te mea nui ka āwhina hoki ki te puipui i ngā rawa. Hei tauira tētahi whare 50 pito kei reira, ka taea te penapena i te 12% o te taumaha o te rebar, arā, he iti ake te hia o te kōnireti e hiahiatia ana, ā, he tere ake te wā hanganga. E whakaatu mai ana ngā ripoata rangahau mai i ngā wāhi hanganga pūmahara, ko ngā whare e whakamahi nei i ngā kōpae pīroto e 30% pea ake ngā pakaru o te parirau ina uru ana ki ngā uta ōrite ki ērā hanga e whakamahi ana i ngā lap splice tāpoi. Nō reira e tono ake ana ētahi anō mātai hanganga ki ēnei kōpae mō ngā tūru whatitiri me ngā whare teitei, nā te mea he tino nui te āhua o te tika o te whakauru, he mea matua herekore ngā pūnaha tautoko, ā, me mau tonu te hanganga katoa mō ngā tekau tau kia kaua ai e pakaru.
| Te Painga o te Kōpae | Te Herekore o te Lap Splice | Te Pānga Hanganga |
|---|---|---|
| tuku uara 100% | Ngā pokapoka parirau ki ngā hononga | Whakakoreia ngā wāhi māmāriki ki ngā takotoranga |
| Te whanake ārai rū whenua | Te mōrearea o te pakaru māmāri | Aukatia te pakaru i ngā rū whenua |
| Kua whakaitia te uru atu o te rebar | Mākeake tae atu ki te 40% o ngā rākau | Whakaihii ake i te rahi me ngā utu o te kōnitere |
Me pēhea ngā Kupenga Rebar Kaokao e āki ai te whakauru marino
Ngā tikanga o te whakahaere Axial me Rotational kei roto i ngā Hononga Kaokao
Ko ngā kōpae pūtini rebar e whiwhi ana i tā rātou tikanga mai i ērā piko āhuatia e hāngai ana ki te nuinga o te nekeneke i te pito ki te taha, ā, ka aukati hoki i ngā mea kia kore ai e porohia. Mā te piko tōrangi e rere ana i te roa katoa, kei te pā tonu ngā wāhanga kia kore ai e slipa i te wā e pā ana ngā kaha ki tētahi taha, ki tētahi atu rānei. Ko te ara e pākatata ana ēnei piko anuanu hoki ka aukati i ngā raru poroheke i te wā o te pouri. Ka pupuri hoki ēnei kōpae i te āhua tika rawa, e noho ana i roto i te 1 kīwai i te kona, ā, he itinga tekau-mano ia mano te iti ake i te rārangi, āno he aitua e takirua ana ngā mea. Ko ngā hononga lap e mahi āhua rerekē ana nā te mea ka mātaraia e ngā kaimahi ngā pou mā te ringa, ka aronga ai ki ngā wehenga. Engari ko ngā pūnaha piko e tautoko ana i ētahi mea pai ake nā te mea ka taea te tirotiro i ngā hua ki te wāhi, ka whakarite kia tukuna tika ngā uta puta noa i te hanganga, ā, ka pupuri i ngā whare kia haumaru, kia pūmau hoki.
Tauānga Tuhinga: Ngā Kōpae Piko Tōrangi a Rollfit ki ngā Paretu Heru Rahi
I te hīkoi 60 i te tūāpapa i whaiwhai ngā #40 rebar ki ngā pāreti o te kiko me te noho āhuatanga o 2 mm. I awhina te punaha coupler paratareo i ngā hononga kaua ko te huri i te reinforcement—hei vantex nui ki ngā wāhi iti. I arataki ngā tikanga tūmatanui:
- Kua tapia marino, kua rōrahi ngā tapa bar i waho i te tūru
- Te huinga mana torika ki te 350 Nm ±5%
- Te whakapono mā te tohu atamira i muri i ia pouri
Kua tutuki katoa ngā hononga 3,200 ki te korero matua, kāore he mahi whakatika. Kua anga ngā pāreti o te kiko i te whakamātau kawe kaha ake i te 150% o te uara hoahoa. Kua penapena te kaupapa i ngā rā 18 tautuhi ki te hononga ohauru—ka whakaatu pea ko ngā coupler marino e whakanui ana i te whakapono hanganga me te uaua hanganga ki ngā waahanga matua.
Taper vs. Parallel Threaded Rebar Coupler: Te Whiriwhiringa i te Punaha Tika
Te Whakatairite i te Mahi: Te Uara Kawe Kaupapa me te Tolerancia Tūhuratanga
Ina kōwhiri ana i ngā kōpua mō ngā whakamahinga hanganga matua, me āta whai whakaaro ngā inihinihini ki ētahi take matua e rua: te pēhea o te tuku uara, me te pēhea te māmā i te wā o te whakauru. Kei ngā pūnaha porotiti te āhuatanga o te whakarereketanga ake i te wāhi e iti ai te wā whakarerekenga i ngā wāhi pakari, i ngā tikanga papa hāngai rerekē hoki, e te 40%. Heoi anō, he take kei reira. Ko te āhua kotahi e pai ai te whakauru, engari e āhua hāpai ai i ngā wāhi takirua, arā ka tino e 90% pea te kaha tōrite atu ki te kaha o te rebar tikanga. I te taha arumoni, ko ngā kōpua parareka tāpiripiri e mahi tino pai ake ana e ai ki ngā whiu ACI 318, e eke ana i waenganui i te 98% ki te 102% o te kaha pou nā te hononga tāpiripiri ōrite. Me whakahaere tika ake i te huri, otirā, i roto i te ±5 kīraro, engari i te tirohanga hanganga, kei te noho rite ki te rebar tōpu. Nō reira i te taumata mahi nei, ka huringa ngā kōpua hei wae wae matua i ngā whare e hoahia ana ki ngā rū whenua, i ngā wāhanga pokapoka o ngā whare tūāpapa, i reira ko te kintanga hanganga he mea anuanu.
| Āhuatanga | Ko ngā Kiko e Narrow ana | Ko ngā Kiko Whakapaerua |
|---|---|---|
| Te Ihi o te Tuku Uunga | 90% uanga pūero | 98–102% uanga pūero |
| Te Manawarite Whakauru | whakaaetanga huri ±15° | whakapono huri ±5° |
| Ngā Whakamahinga Tino Whai Tikanga | Ngā Huinga, wāhi iti | Ngā takotoranga tikokiko, ngā rohe rū whenua |
Ko te whiringa e hāngai ana ki ngā take matua o te kaupapa: ko ngā koupene tēra e matapōkai ake ana i te āhua, i reira e kore ai e taea te tautohe i ngā wāhi iti; ko ngā punaha parareka e matapōkai ake ana i te ahurea o te hanganga i reira ko te aronga ki te pikinga o te hikoinga he mea nui.
Ngā Tikanga Pai Mō Te Whakauru I Ngā Koupene Pīroiroi Pūtōrino
Ko te whakauru tika e whakatau tūmatata i te mahi o te hanganga—ko ngā itinga e piki ake ana i te raru o te pakaru o te hononga e 40%, ā, e ai ki ngā āta toronga haumaru hanga i te tau 2023. Ko te whakamātau mara kei te takotoranga o ngā putanga pai, ā, e toru ngā whāinga e manaakitia ana e te ture.
Whakamātau Mara: Ngā Ture Mō Te Aromatawai, Torque, Me Te Parakirihana o Te Mata
Me whakamātau te aromatawai ara i roto i te 1.5° e whakamahia ana ngā taumata laser; ko ngā wehenga e piki ake i te 3° e heke iho ai te mātai kawe hiko e 25%. Me whakamahi taputapu āwhina e tautapua ana ki ngā uara e tohua ana e te kaihanga—e 200–450 Nm noa atu, e hāngai ana ki te tōpata o te pūtōrino—me tuhia katoa ngā panonitanga ki te rorohiko mō te āta toronga.
Ko te parakirihana o te mata he mea anoo nui:
- Tāwhai whakamomori, hinu, me te papa toki mā te paraihe wire
- Whakapūmau i te kounga o ngā āhua mā te whakamahi i ngā tapa go/no-go i mua i te hono
- Whakapai atu he rongoā anti-seize māmā hei whakaiti i te koraki galvanic
Hei whakamutunga, ka mahia ngā tātai tāwhai i runga i te 5% o ngā hononga kua whiriwhiria arorangi i te rohe. Ka aukati tēnei takotoranga anuanu ki te mahi anō, ka whakarite i te arataki, me te whakarite i te tuku koretake kotahi i te puna katoa.
FAQ
He aha te take e nui ana ngā hononga rebar threaded i te hanga?
He mea nui ngā hononga rebar threaded i te hanga nā te mea ka tukuna e rātou ngā hononga mekanik kaha e whakapakari ai i te anga ahumahi, e iti ai ngā piko piko, e whakapai ai i te haumāta, me te penapena rawa me te wā i te wā o te huringa.
Me pēhea e pai ai ngā hononga rebar threaded ki ngā hanga i ngā rohe marangai?
I ngā rohe e noho ana ngā marangai, ko te āhuatanga maroke o ngā hononga rebar threaded e āwhina ana ki te whangai i ngā ngaru pakanga, e aukati ana i te pakanga pitoiti me te tino tuohu i ngā takotoranga, e tuku ana i te ductility marangai.
He aha ngā hīnga herehere mo ngā kaweneta piko rebar?
Ko te whakauru he āhuatanga tika, te whakamahi pūhui tata, te parakirihana i te mata pērā i te tango i te pora, me te whakamātau i ngā thread kia tiakina ai ngā hononga me te pupuri i te mahi o te hanganga.
