Ngā Pūrongo - Ngā Whakatakotoranga, Ngā Rauemi me Ngā Whakamahinga o te Kurupae H ASTM | Kaiwhakarato Kurupae Whānui Rino Hanganga

Ahakoa kei te tere haere te haumi ki ngā hanganga o te ao i Amerika Te Raki, Amerika Latina, me Āhia ki te Tonga-mā-rāwhiti,Kurupae H ASTMKei roto tonu i te rarangi o ngā wāhanga maitai hanganga rongonui e whakamahia ana i roto i ngā hanganga arumoni, ahumahi, me ngā hanganga hanganga. He kaha te pikaunga kawenga, he pai te pumau o ngā āhuatanga, ā, e tutuki ana i ngā paerewa o Amerika. He whānuitia te whakamahinga i roto i ngā pūnaha hanga e whakarato ana i te mahi teitei puta noa i te ao.

Ngā Whakatakotoranga Matua o te ASTM

Ko ngā kurupae ASTM H (e mōhiotia ana ko ngā kurupae whānui) ka hangaia i runga i ngā paerewa e whai ake nei:

ASTM A36 H-high– Te maitai waro hanganga whānui mō ngā whare me ngā kaupapa ahumahi māmā
ASTM A572 H-high– He maitai HSLA me te ōwehenga kaha-ki-taumaha kua whakapaitia
ASTM A992 H-high– Te momo pai mō ngā kurupae whānui hanganga i te mākete o Amerika
ASTM A588 H-high– He rino ātete-waikura mō ngā piriti me ngā hanganga o waho

I roto i ēnei, ko te momo tino noa i te US koASTM A992 kurupae whānui flange, he tino taurite ngā āhuatanga o te kaha, te ngāwari ki te whakarewa me te ngāwari ki te hono.

Ngā Āhuatanga Rauemi me te Mahi Mīhini

Ngā Taupānga Matua

Ngā āhuatanga ā-mīhini noa (he rerekē i runga i te taumata):

Te Kaha o te Hua: 250–345 MPa (36–50 ksi me runga ake)
Kaha Kume: 400–550 MPa
He tino pai te whakarewa me te hanganga
He kaha te ātete ki te piko me te pēhanga

Ko te wāhanga whakawhiti āhua-H e whakarato ana i:

1. Teitei o te wāhanga modulus

2. Te tohatoha kawenga whai hua

3. He iti ake te whakamahinga maitai i whakaritea ki ngā kurupae-I tuku iho

4. Mahi pai rawa atu i roto i ngā āhuatanga ru whenua me te hau-kawenga

Whakamutunga o te ASTM H Beam

Ko te ASTM H Beam, te Whānui Flange Beam rānei, he hua matua i roto i te hanganga maitai i ēnei rā. Ahakoa he whare putunga ahumahi, he hanganga maitai arumoni, he hangarau piriti rānei te kaupapa, ka homai e ngā kurupae H hanganga ASTM te kaha, te pono me te tutuki i ngā whakaritenga puta noa i te ao.

Ki ngā kaihoko maitai me ngā kaimahi hanga whare, he mea nui kia whiriwhiria e rātou tētahi kaiwhakarato kurupae H pono e tutuki ana i ngā whakaritenga kounga teitei, ā, kua whakamanahia hoki e ngā paearu o te ao kia mau tonu ai tō rātou whakataetae i te tau 2026 me tua atu.
