Ubwino Welded Cold Anapanga Welded Structural Mapaipi

M'magawo omanga ndi kupanga, kusankha kwa zida zowotcherera ndi njira zimagwira ntchito yofunika kwambiri pakukwaniritsa bwino ntchito iliyonse.Chimodzi mwazinthu zotere zomwe zatchuka m'zaka zaposachedwa ndi chitoliro chozizira chopangidwa ndi welded.Zogulitsa zatsopanozi zimapereka maubwino angapo kuposa mapaipi achikhalidwe opanda msoko kapena welded, makamaka mapaipi ozungulira.

 Kuzizira anapanga welded structuralchitoliro chimapangidwa kudzera munjira yozizira, yomwe imaphatikizapo kupindika ndi kupanga zomangira zachitsulo mu mawonekedwe omwe akufuna.Chotsatira chake ndi chitoliro chomwe chimakhala champhamvu komanso chokhazikika, komabe chopepuka komanso chosavuta kugwiritsa ntchito.Kuphatikiza apo, kuzizira kopanga kumapangitsa kuti chitolirocho chikhalebe chokhazikika komanso cholondola, ndikupangitsa kuti ikhale yabwino yowotcherera.

Kuyesedwa kwa Hydrostatic

Utali uliwonse wa chitoliro uyenera kuyesedwa ndi wopanga ku mphamvu ya hydrostatic yomwe idzapangitse mukhoma wa chitoliro kupsinjika kosachepera 60% ya mphamvu zokolola zosachepera zomwe zafotokozedwa kutentha.Kupanikizika kumatsimikiziridwa ndi equation yotsatirayi:
P=2St/D

Kusiyanasiyana Kololedwa Pakulemera ndi Makulidwe

Utali uliwonse wa chitoliro uyenera kuyezedwa padera ndipo kulemera kwake sikuyenera kusiyana kuposa 10% kuposa kapena 5.5% pansi pa kulemera kwake, kuwerengeredwa pogwiritsa ntchito kutalika kwake ndi kulemera kwake pa kutalika kwake.
Kuzungulira kwakunja sikuyenera kusiyanasiyana kupitilira ± 1% kuchokera m'mimba mwake mwadzina.
Makulidwe a khoma nthawi iliyonse sayenera kupitirira 12.5% ​​pansi pa makulidwe omwe atchulidwa.

Utali

Kutalika kwachisawawa chimodzi: 16 mpaka 25ft (4.88 mpaka 7.62m)
Kutalika kwapawiri: kupitirira 25ft mpaka 35ft(7.62 mpaka 10.67m)
Utali wofanana: kusiyanasiyana kovomerezeka ±1in

Kutha

Milu ya mipope iyenera kukhala ndi malekezero omveka, ndipo ma burrs kumapeto kwake adzachotsedwa.
Pamene mapeto a chitoliro amatchulidwa kuti ndi bevel amatha, ngodya iyenera kukhala 30 mpaka 35 digiri

Mmodzi wa waukulu ubwino ozizira anapanga welded structuralchitoliro chowotchererandi mphamvu yake yopirira kutentha kwakukulu ndi zipsinjo.Mosiyana ndi mapaipi achikhalidwe, omwe amatha kuwonongeka ndi mitundu ina, mapaipi ozizira amapangidwa kuti athe kupirira zovuta za kuwotcherera ndi njira zina zamakampani.Izi zimawapangitsa kukhala abwino kuti agwiritsidwe ntchito pazinthu zosiyanasiyana kuyambira pakumanga zomanga mpaka ntchito zomanga.

Ubwino wina wa chitoliro chozizira chopangidwa ndi welded structural chitoliro ndichokwera mtengo.Kuzizira kumapanga njira yopangira mapaipi osiyanasiyana kukula kwake ndi mawonekedwe, kuchepetsa kufunikira kwa njira zotsika mtengo zoponyera ndi makina.Izi zimapangitsa kuti mankhwalawa akhale otsika mtengo komanso odalirika ngati chitoliro chopanda msoko kapena chowotcherera.Kuonjezera apo, chikhalidwe chopepuka cha chitoliro chozizira chimapangitsa kuti mayendedwe ndi kuyika zikhale zosavuta komanso zotsika mtengo, ndikuwonjezera kukopa kwake.

Machubu a Spiral seam amapindula makamaka ndi kuzizira kupanga.Kulimba kwachilengedwe komanso kusinthasintha kwa machubu opangidwa ozizira amawapangitsa kukhala abwino popanga zolumikizana zolimba komanso zosadukiza.Izi zimawapangitsa kukhala chisankho chabwino kwambiri pazogwiritsa ntchito monga ngalande zapansi panthaka, mizere yamadzi ngakhalenso ulimi wothirira.Kuonjezera apo, malo osalala a mapaipi opangidwa ozizira amachepetsa chiopsezo cha kukangana ndi kuvala, kukulitsa moyo wa chitoliro ndi kuchepetsa kufunika kokonza ndi kukonzanso.

Ponseponse, chitoliro chozizira chopangidwa ndi welded structural chitoliro chimapereka zabwino zingapo zomwe zimapangitsa kukhala chisankho chabwino kwambiri pazowotcherera, makamaka chitoliro cha spiral seam.Mphamvu zawo, kukhazikika kwawo komanso kutsika mtengo zimawapangitsa kukhala chisankho chokongola kwa mafakitale osiyanasiyana, kuyambira pakumanga mpaka kupanga.Pomwe kufunikira kwa zida zapamwamba kwambiri, zodalirika zikupitilira kukula, chitoliro chozizira chopangidwa ndi welded chidzakhala chisankho chodziwika bwino pakugwiritsa ntchito kuwotcherera.
