Global Demand for Structural Steel: Kukwira kweASTM A572 uye Q235/Q345 I-Beams

Mumakore achangopfuura, indasitiri yekuvaka yakaona kuwedzera kukuru mukudiwa kwesimbi yezvimiro, kunyanya I-yakaita sesimbi profiles seASTM A572 uye Q235 / Q345. Izvi zvinhu zvakakosha pakuvaka zvivakwa zvakasimba, uye mukurumbira wazvo mumusika wepasi rose chiratidzo chekuvimbika kwavo uye kuita zvakasiyana.

Kunzwisisa Structural Steel

Structural steel iboka resimbi rinoshandiswa kugadzira zvinhu zvekuvaka mumhando dzakasiyana siyana. Iyo inozivikanwa nehukuru hwayo hwekusimba-kusvika-huremu, ichiita sarudzo yakanaka yekuvaka zvivakwa, mabhiriji, uye zvimwe zvivakwa. Pakati pemhando dzakasiyana dzesimbi yezvimiro, I-matanda, anozivikanwawo seH-matanda kana H-zvikamu, anofarirwa zvakanyanya nekuda kwekugona kwavo kutsigira mitoro inorema uku ichideredza kushandiswa kwezvinhu.

ASTM A572: Chiyero cheSimbi Yakakwirira-Simba

ASTM A572 ndeyekutsanangurwa kwepamusoro-simba rakaderera-alloy columbium-vanadium structural simbi. Inoshandiswa zvakanyanya mukuvaka uye inozivikanwa nekunaka kwayo weldability uye machinability. Simbi iyi inowanikwa mumagiredhi akasiyana-siyana, Grade 50 ichiva ndiyo inonyanya kushandiswa pakugadzira zvinhu. Simba regoho repamusoro reASTM A572 rinoita kuti ive yakakodzera kushandiswa munzvimbo dzinodiwa, uko kutendeseka kwechimiro kwakakosha.

Q235 uye Q345: The Chinese Standards

Kuwedzera kune ASTM zviyero, musika weChinese unoshandisa Q235 uye Q345 simbi mamakisi, ayo anozivikanwa zvakanyanya nekuda kwesimba rawo uye kuita zvakasiyana. Q235 isimbi yakaderera kabhoni structural simbi iyo inowanzoshandiswa mukuvaka, nepo Q345 iri yakakwirira-yakasimba yakaderera-alloy simbi inopa yakagadziridzwa michina. Magiredhi ese ari maviri akakosha kune akasiyana maapplication, kusanganisira kuvakwa kwezvivakwa, mabhiriji, uye mamwe mapurojekiti ezvivakwa.

Iyo Global Market yeI-Beams

Musika wepasi rose weI-beam wanga uchikura nekukurumidza, uchitungamirwa nekukura kweindasitiri yekuvaka mune hupfumi huri kusimukira. Nyika dzakaita seChina, India, neBrazil dziri kusangana nekukura kwekuvaka, zvichikonzera kuwedzera kudiwa kwesimbi yezvimiro. Izvo zvakasiyana-siyana zveI-matanda zvinoita kuti zvive zvakakodzera kune zvakasiyana-siyana zvekushandisa, kubva kune zvivako zvekugara kusvika kumapurojekiti makuru ekutengeserana.

Mutengo weI-matanda, seaya akagadzirwa kubva kuASTM A572 uye Q235/Q345, wanga wakagadzikana, nemitengo yazvino yemusika ichitenderera madhora mazana mana nemakumi mashanu patani. Kugona uku, kwakasanganiswa nekusimba kwechinhu uye kusimba, kwakabatsira mukuzivikanwa kwayo pakati pevavaki nemakondirakiti pasi rese.

Zvishandiso zveI-Beams muKuvaka

I-matanda anoshandiswa mumhando dzakasiyana dzekuvaka, kusanganisira:

1. Zvivakwa zvekuvaka: I-matanda anowanzo shandiswa sechinhu chekutanga chechimiro muchimiro chezvivakwa. Chimiro chavo chinobvumira kugovewa kwakanaka kwemutoro, zvichiita kuti ive yakanakira kutsigira pasi nematenga.
2. Mabhiriji: Simba uye kusimba kweI-matanda kunoita kuti ave sarudzo yakakurumbira yekuvaka mabhiriji. Dzinogona kumira mitoro inorema uye inoshingirira kukotama uye deformation.
3. Zvimiro zveMaindasitiri: Mafekitori nematura anowanzo shandisa maI-matanda mukuvaka kwavo nekuda kwekugona kwavo kutsigira michina inorema nemidziyo.
4. Kuvaka Kwekugara: Muzvivakwa zvekugara, I-matanda anoshandiswa kugadzira nzvimbo dzakavhurika uye nzvimbo dzakakura pasina kudiwa kwemamwe makoramu ekutsigira.

Sustainability uye Mafungiro Ezvakatipoteredza

Sezvo indasitiri yekuvaka iri kuramba ichikura, kune kuwedzera kutarisisa kwekusimudzira uye kukanganisa kwezvakatipoteredza. Simbi yezvivakwa, kusanganisira I-matanda, inodzokororwa, zvichiita kuti ive sarudzo ine hushamwari pamapurojekiti ekuvaka. Vazhinji vagadziri vari kutora maitiro akasimba, akadai sekushandisa simbi yakadzokororwa uye kuderedza marara panguva yekugadzira.

Matambudziko muIndasitiri Yesimbi

Pasinei netarisiro yakanaka yemusika wesimbi, iyo indasitiri inotarisana nematambudziko akati wandei. Kuchinja-chinja kwemitengo yezvinhu zvakasvibirira, mutero wekutengesa, uye kukanganiswa kweketani yekugovera zvinogona kukanganisa kuwanikwa uye mutengo wezvigadzirwa zvesimbi. Pamusoro pezvo, iyo indasitiri inofanirwa kufamba-famba zvinodikanwa zvekutonga uye zviyero zvezvakatipoteredza, izvo zvinogona kusiyana nedunhu.

Ramangwana Trends muStructural Simbi

Tichitarisa kumberi, musika wesimbi wesimbi unotarisirwa kuenderera mberi nekukura kwayo. Hutsva mukugadzirwa kwesimbi nekugadzirisa zvinogona kuwedzera kushanda uye kusimba kwezvigadzirwa zvesimbi. Zvakare, kuwedzera kutorwa kwehunyanzvi hwekuvaka, senge modular kuvaka uye prefabrication, kunofambisa kudiwa kwemhando yepamusoro simbi yekuvaka.

Mhedziso

Kudiwa kwepasi rose kwesimbi yezvimiro, kunyanya ASTM A572 uye Q235/Q345 I-matanda, kuri kuwedzera sezvo indasitiri yekuvaka iri kuwedzera. Zvishandiso izvi zvinopa simba, kusimba, uye kuita zvakasiyana-siyana, zvichiita kuti zvive zvakakosha kune zvakasiyana-siyana zvekushandisa. Sezvo indasitiri inoshanduka, zvichave zvakakosha kuti vagadziri uye vavaki vajairane nekuchinja kwemamiriro emusika uye kugashira maitiro akasimba kuti ave nechokwadi cheramangwana rakagadzikana resimbi yezvimiro. Nemitengo yakasara ichikwikwidza uye mabhenefiti ekushandisa I-matanda akajeka, ramangwana rinotaridzika rakajeka kune ichi chikamu chakakosha chekuvaka kwemazuva ano.
