Te Tino Whakaaetanga Hou mō te H-Section Steel Hōu hei Rerekētia i te Mē 1

I te 26 o Oketopa 2024, i whakaaetia, i whakaputaina hoki e te National Market Supervision and Administration Bureau o Haina me te National Standardization Administration te paerewa ā-motu GB/T 11263-2024 Hot-rolled H-Section Steel and Split T-Section Steel mā te Announc

Ko ngā huringa matua ki tēnei paerewa ko: ngā huringa ki te whakarōpūtanga me ngā waehere; ngā huringa ki te whakarōpūtanga o te teitei, te whanui, te matotoru, te pokanga pokapū, me te pokanga āhei mō te piko o te kōhao; te tāpiri i te pokanga

I tēnei whakarevision, i te nuinga o ngā tohu matua pērā i te whakarahi i te nui o te taumaha kua whakaputua, ko te nuinga o te whai hua kua whakamahia ki te whakapai ake i ngā whakaritenga me ngā tauira. Kua whakarahia ngā whakaritenga rahi ki H1700×550 mm, ā, kua piki ake te maha o ngā tauira huinga inuata H kia te 150%, ā, kua piki hoki te maha o ngā whakaritenga kia te 230%. O runga i ēnei, e 24 ngā tauira, e 141 ngā whakaritenga o te inuata H nui rawa atu e pā ana ki te teitei e piki ake i te 1000 mm me te whānui e piki ake i te 300 mm, e whakamahia nui ana i te hanga aratene. Kua eke te tauwhitinga hou ki te taumata matua o te ao.

Kua whakapai ake tēnei tāuru i te rāwekenga o ngā tohu mō te huinga kohatu H, kua whakakīia te kore i te kohatu H rahi rawa atu i te whenua me te ao, ā, kua whakatutuki hoki i ngā hiahia o te hanga whare kohatu. Ka āwhina te whakamahinga o tēnei tāuru i te whānuitanga o te whakamahi kohatu H rāpō ki ngā hanga kohatu, ka hāwhai i te whakaurutanga o ngā hua kohatu H ki te ao, ka tuku i ngā tikanga tūturu mō te whiriwhiri rāwekenga mō te hoahoa me te hanga i ngā hanga kohatu o te whenua, ā, ka waihanga hoki i ngā tikanga mō te whakapai ake i te takotoranga o te ahumahi.
