Zogulitsa zopangidwa ndi mafakitale achi China obwezeretsedwanso

Ndife opanga luso. Kupambana kwambiri chifukwa cha kutsimikizika kofunikira pamsika wake wopangidwa ndi zitsulo zaku China zopangidwa ndi mafakitale okhazikika kaboni Mtengo wogulitsa kwambiri wogulitsa kwamuyaya ku China.
Ndife opanga luso. Kupeza ambiri kuchokera ku rigiriti yofunika kwambiri pamsika wakeChina rebar ndi HRB500 Steel Resuel, Fakitale yathu imangonena za "mtundu woyamba, kukula", ndipo zimatenga "bizinesi yoona, kupindulira" monga cholinga chathu. Mamembala onse amakomodira chifukwa cha chithandizo cha makasitomala akale komanso atsopano. Tipitilizabe kugwira ntchito molimbika ndikukupatsani njira zapamwamba kwambiri komanso ntchito.

kupatula

Mbale yotentha yokulungidwa imagawika magiredi atatu: hrb335 (kalasi yakale), kalasi atatu HRB400 (kalasi yakale) ndi 20mdiv, 20mndi), ndi kalasi anayi HRB500.
Pali njira ziwiri zomwe zimagwiritsidwa ntchito popanga mipiringidzo yolimbitsa:Chimodzi ndicholinga malinga ndi mawonekedwe a geometric, ndipo winayo akuyenera kuloza kapena kuloza malinga ndi mawonekedwe a gawo la zotchinga ndi kutalika kwa mipiringidzo. Mtundu wa II.this makamaka amawonetsa magwiridwe antchito ogwirira ntchito.

Lachiwiri ndi molingana ndi gawo la ntchito (kalasi), monga gawo la kukhazikitsidwa kwapano mdziko langa, zobwezeretsedwayo ndi (GB1499.2-2007), ndi mphamvu / mphamvu / kunenepa. Kalasi; Mu muyezo wa mafakitale wa ku Japan (Ji Sg31112), zitsulo zachitsulo zimagawika m'magulu asanu malinga ndi zinthu zawo zokwanira; Mu Standard Standard (BS4461), masitepe angapo a mayeso a steve a share amatchulidwanso. Kuphatikiza apo, mipiringidzo yachitsulo imathanso kugwiritsidwa ntchito ndi kugwiritsidwa ntchito, monga miyala wamba yachitsulo kuti ilimbikitsidwe konkriti ndi kutentha kwa konkriti yolumikizidwa.

palaleni

1) Kuchulukitsa kwa dambonal nomwel ndikulimbikitsidwa
Maofesiwa a nomwenal a shael mitanda imachokera ku 6 mpaka 50mm, ndipo muyezo wodalirika umalimbikitsidwa ma miniti a chitsulo chachitsulo.
2) kupatuka kwa mawonekedwe a mawonekedwe ndi kukula kwa zitsulo za nthiti
Mfundo zopangidwa ndi zitsulo zosewerera ziyenera kukwaniritsa zofunikira zotsatirazi:
Angle β pakati pa nthiti yosinthira ndi chitsulo cha chitsulo sichiyenera kukhala chosakwana madigiri 45. Kutalika kwa ngodya sikuli koposa madigiri 70, chitsogozo cha mipiringidzo mbali zonse ziwiri za bar yachitsulo ziyenera kukhala zosiyana;
Kutalika kwa nomwelunal l kwa mipiringidzo yotchinga sikuyenera kukhala wamkulu kuposa 0.7 nthawi ndi mwadzidzidzi kwa mipiringidzo;
Mchenga α pakati pa kumbali ya nthiti yosinthiratu ndi pamwamba pa bar yachitsulo sikudzakhala kochepera madigiri 45;
Kuchuluka kwa mipata (kuphatikiza m'lifupi wa nthiti yayitali) kumapeto kwa nthiti zotsekemera pa bar yachitsulo sikungakhale kotheratu kwa 20% yozungulira bala;
Mzere wa nomwel wa share share si wopitilira 12mm, nthiti yachibale sayenera kukhala yochepera 0,055; Maondo a nomwel ndi 14mm ndi 16mm, malo ocheperako sayenera kukhala ochepera 0.060; Maondo a nomwel ndi akulu kwambiri kuposa 16mm, malo ocheperako sayenera kukhala ochepera 0,065. Onani Zakumapeto c kuti muwerengere nthiti yachidule.
Zitsulo zozimiririka zimakhala ndi mipiringidzo yayitali, ndipo kulinso iwo opanda mipiringidzo yaitali;

3) kutalika ndi kupatuka kovomerezeka
Imodzi. utali
Mitengo yachitsulo nthawi zambiri imaperekedwa motalika, ndipo kutalika kwake kuyenera kuwonetsedwa mu mgwirizano;
Mabatani opanga zitsulo amatha kuperekedwa m'masitolo, mpukutu uliwonse uyenera kukhala bala imodzi yachitsulo, ndipo 5% ya chiwerengero cha ma rolls pa boll (osakwana ma roll awiri) ali ndi mipiringidzo iwiri yachitsulo. Ma disk olemera komanso disk mulingo wotsimikizika kudzera pakukambirana pakati pa wotsatsa ndi wogula.
b. Kulezana
Kutalika kokhazikika kumaperekedwa, kupatuka kwa kutalika kwa bala yachitsulo sikoposa ± 25mm;
Kutalika kochepa kumafunikira, kupatukako ndi + 50 50mm;
Kutalika kwakukulu pakufunika, kupatuka ndi -50mm.
c. Kupindika ndi kumatha
Mapeto a bala yachitsulo amayenera kudulidwa molunjika, ndipo kuphatikizika kwakomweko sikukhudza kugwiritsa ntchito

chithunzi

Ndife opanga luso. Kupambana kwambiri chifukwa cha kutsimikizika kofunikira pamsika wake wopangidwa ndi zitsulo zaku China zopangidwa ndi mafakitale okhazikika kaboni Mtengo wogulitsa kwambiri wogulitsa kwamuyaya ku China.
Kusaka ZinthuChina rebar ndi HRB500 Steel Resuel, Fakitale yathu imangonena za "mtundu woyamba, kukula", ndipo zimatenga "bizinesi yoona, kupindulira" monga cholinga chathu. Mamembala onse amakomodira chifukwa cha chithandizo cha makasitomala akale komanso atsopano. Tipitilizabe kugwira ntchito molimbika ndikukupatsani njira zapamwamba kwambiri komanso ntchito.
