Kua tau te paerewa hou mō te rino rebar, ā, ka whakatinanahia mana i te mutunga o Hepetema.

Ka whakatinanahia mana te putanga hou o te paerewa ā-motu mō te rino rebar GB 1499.2-2024 "te rino mō te raima whakapakari wāhanga 2: ngā pae rino rara wera" i te 25 o Hepetema, 2024.

I roto i te wā poto, he iti noa te pānga o te whakatinanatanga o te paerewa hou ki te utu opā rakaute whakaputa me te hokohoko, engari mō te wā roa e whakaata ana i te ariā ārahi whānui o te kaupapa here ki te whakapai ake i te kounga o ngā hua o roto me te whakatairanga i ngā umanga maitai ki te pito waenga me te pito teitei o te mekameka ahumahi.
I. Ngā huringa nui o te paerewa hou: te whakapai ake i te kounga me te auahatanga tukanga
Nā te whakatinanatanga o te paerewa GB 1499.2-2024 kua maha ngā panonitanga nui kua puta, hei whakapai ake i te kounga o ngā hua rebar me te whakarite i ngā paerewa rebar o Haina kia rite ki ngā paerewa o te ao. Anei ngā panonitanga matua e whā:

1. Ka whakakaha ake te paerewa hou i ngā herenga taumaha mō te rebar. Ina koa, ko te rerekētanga e whakaaetia ana mō te rebar 6-12 mm te whānui ko ±5.5%, ko te 14-20 mm ko +4.5%, ā, ko te 22-50 mm ko +3.5%. Ka pā tika tēnei huringa ki te tika o te whakaputanga o te rebar, me whakapai ake ngā kaihanga i te taumata o ngā tukanga whakaputa me ngā āheinga whakahaere kounga.
2. Mō ngā momo rebar kaha-teitei pērā iHRB500E, HRBF600Eme te HRB600, e whakahau ana te paerewa hou kia whakamahia te tukanga whakamahine koko. Mā tēnei whakaritenga ka tino whakapai ake i te kounga me te pumau o te mahi o ēnei mea kaha-teiteingā pae rino, me te whakatairanga anō i te umanga ki te ahunga o te whanaketanga maitai kaha-tiketike.
3. Mō ngā āhuatanga tono motuhake, ka whakauruhia e te paerewa hou ngā whakaritenga mahi ngenge. Mā tēnei huringa ka whakapai ake i te roa o te mahi me te haumaru o te rebar i raro i ngā kawenga hihiri, inā koa mō ngā piriti, ngā whare teitei me ētahi atu kaupapa he nui ngā whakaritenga mō te mahi ngenge.
4. Ka whakahoutia e te paerewa ngā tikanga tauira me ngā tukanga whakamātautau, tae atu ki te tāpiri i tētahi whakamātautau piko whakamuri mō te pae whakau "E". Mā ēnei huringa ka whakapai ake i te tika me te pono o te whakamātautau kounga, engari ka piki ake pea te utu whakamātautau mō ngā kaihanga.
Tuarua, te pānga ki ngā utu whakaputa
Mā te whakatinanatanga o te paerewa hou ka whai hua ki te upoko o ngā umanga hanga miro ki te whakapai ake i te kounga hua, ki te whakanui ake i te whakataetae mākete, engari ka puta mai hoki he utu whakaputa iti: e ai ki ngā rangahau, ko te upoko o ngā umanga hanga maitai, e ai ki te paerewa hou, ka piki ake ngā utu whakaputa hua tata ki te 20 yuan/tana.
Tuatoru, te pānga o te mākete

Mā te paerewa hou ka whakatairanga i te whanaketanga me te whakamahinga o ngā hua maitai kaha ake. Hei tauira, tera pea ka nui ake te aro ki ngā pae maitai ru kaha-tino-teitei 650 MPa. Mā tēnei panonitanga ka arahi ki ngā huringa o te ranunga hua me te tono mākete, ka pai ake pea ki ngā mira maitai ka taea te whakaputa rauemi matatau.
I te whakapikinga ake i ngā paerewa, ka piki ake te hiahia o te mākete mō ngā rino kounga teitei. Tērā pea ka nui ake te utu mō ngā rauemi e tutuki ana i ngā paerewa hou, ā, ka akiaki i ngā kamupene ki te whakapai ake i te kounga o ngā hua.
