Me pēhea te whiriwhiri i te H-beam mō tō kaupapa

I roto i te taiao hurihuri tere o te hanga whare me te hangarau ā-iwi, ko teH-hiku(raneikurupae whānui) he mea tino nui te kōwhiringa mō te haumaru, te pumau me te ōhanga o te kaupapa katoa. Mai i te whare teitei ki te whare putunga ahumahi, mai i te piriti ki te whare arumoni, mā te kōwhiringa hē o te kurupae H ka raru pea te hanganga, ka nui rawa te utu, ka tūpono rānei te ora.

Ngā Take Matua mō te Kōwhiri i te H-Rangi Tika

Ko te kaupapa o te whiriwhiri ka tīmata mā te mōhio ki ngā kawenga me tautoko e te kurupae. Ko ētahi o ēnei:

1. Ngā Utaina Mate (Taumaha Tuturu o te Whare)

2. Ngā kawenga ora (tangata, taonga, motuka, hukarere, me ētahi atu)

3. Ngā kawenga hihiri (hau, kaha rū whenua)

Ka whakamahia e ngā tohunga hangarau hanganga ngā pūmanawa tātari hanganga, ngā waehere hoahoa rānei (hei tauira, AISC i te US, Eurocode i Ūropi, ngā paerewa GB rānei i Haina) hei tatau i ngā wā piko, ngā kaha kutikuti, me ngā rohe piko.

Te Roa o te Whānuitanga me ngā Āhuatanga Tautoko

Ko ngā whāwhātanga roa e hiahiatia ana he kurupae me te kaha o te inertia hei whakaiti i te piko. Hei tauira:

1. Ko ngā whāiti poto (tae atu ki te 6-8m) i roto i ngā whare arumoni māmā ka mahia me ngā wāhanga iti ake ~ 150-200 mm te teitei.

2. Ko ngā kurupae H 10-14" te whānui e hiahiatia ana mō ngā whānui waenga (26-49 putu) i roto i ngā whare putunga.

3. Ko ngā whāriki nunui, ko ngā mahi taumaha rānei (piriti, whare ahumahi nunui) me whai wāhanga 400 mm+, he matotoru ake rānei.

Te Taumata me te Kaha o ngā Rauemi

Ko ngā momo maitai e whakamahia whānuitia ana ko:

1.ASTM A36 / A572 / A992 H Kurupae(Paerewa US, kaha whakaputa tata 250-345 MPa)

2.EN S235 / S275 / S355 H Kurupae(Ture Pākehā)

3.GB Q235 / Q345 H Beam (tikanga Hainamana)

Mā ngā kōeke kaha ake (hei tauira, Q345B, S355 rānei) ka māmā ake ngā wāhanga mō te kawenga kotahi, ka whakaitihia te taumaha katoa o ngā rauemi me te utu o te turanga — he mea tino ātaahua tēnei i ngā rohe rū whenua, i ngā hanganga whare teitei rānei.

Ngā Whakatakotoranga Rahi me ngā Ahu

Ko ngā kurupae H e tohuhia ana e te teitei × te whānui × te matotoru o te whatu × te matotoru o te flange (ine) te hohonu ingoa rānei + te taumaha mō ia putu (emperial, hei tauira, W8×40).

Ko ngā rahi rongonui ko:

1. Mahi Māmā: 100×100 mm ki te 200×100 mm

2. Mahi-waenga: 250×250 mm ki te 300×300 mm

3. Taumaha: 400×200 mm me runga ake

Tirohia ngā tūtohi rahi paerewa mō ngā āhuatanga o te wāhanga (te tere o te inertia, te modulus wāhanga, te taumaha mō ia mita) kia rite ki ngā hiahia o te kaupapa.

Ngā Whakaaroaro Taiao me ngā Kaupapa Motuhake

Ātete ki te waikura: Whakamahia te maitai kua pania, kua peitatia, kua āraia rānei (hei tauira, Corten) ki waho, ki ngā taiao makuku-haumākū rānei.

Te āheinga whakarewa me te āheinga hanga: Tirohia mēnā he hototahi te tohu ki ngā tukanga whakarewa e whakamahia ana i te papaanga.

Te utu me te wātea: Whakaarohia te mahi ki ngā mekameka tuku ā-rohe—ka taea e te nui rawa o ngā whakaritenga te whakanui ake i te utu mā te 20–50%.

Kōrero ki ngā Tohunga

Ka taea te whakamahi i ngā tātaitai ipurangi, i ngā ripanga whānui rānei hei whakakōwae tuatahi, engari me manatoko te kōwhiringa whakamutunga e tētahi miihini hanganga whai raihana. Ka tutuki ngā rahi paerewa i ngā ture, ā, ka pakari te hanganga – kaua rawa e whakawhirinaki ki ngā tātaitanga noa iho.
