Tonse tikudziwa kuti ma bolts amatchedwa mpunga wamakampani. Kodi mukudziwa magulu a mabawuti omwe amagwiritsidwa ntchito kwambiri? Nthawi zambiri, mabawuti a nsanja yopatsira amagawidwa molingana ndi mawonekedwe awo, mulingo wamphamvu, chithandizo chapamwamba, cholinga cholumikizira, zinthu, ndi zina.

Maonekedwe amutu:

Malinga ndi mawonekedwe a mutu wa bawuti, mabawuti omwe amagwiritsidwa ntchito nthawi zambiri amakhala ma bawuti ammutu a hexagonal.

Njira yochizira pamwamba:

Popeza ma bawuti ansanja wamba monga zitoliro zachitsulo ndi nsanja zachitsulo zopindika zimatenthedwa kuti zikwaniritse zofunikira zogwirira ntchito monga kukana komanso kukana dzimbiri, zimagawidwa ngati ma bawuti ansanja yotentha yoviyitsa malata.

Pakati pawo, ziboliboli za nangula ndizofunikira zolumikizira zigawo kuti zitsimikizire chitetezo cha ma pyloni amagetsi. Njira zawo zochizira pamwamba zimaphatikizira kukometsera pang'ono kotentha-kuviika ndi kuthira kothira kotentha kwambiri pagawo lopindidwa.

Mphamvu ya mlingo:

Transmission tower bolts amagawidwa m'magulu anayi: 4.8J, 6.8J, 8.8J ndi 10.9J, pakati pawo ma bolts 6.8J ndi 8.8J amagwiritsidwa ntchito kwambiri.

Cholinga cholumikizira:

Amagawidwa m'malumikizidwe wamba ndi maulumikizidwe ophatikizidwa. Maboti a nangula ndi magawo ophatikizidwa a nsanja yotumizira mphamvu yamagetsi, ndipo nthawi zambiri amagwiritsidwa ntchito kukonza maziko a nsanjayo kuti atsimikizire kuthandizira kokhazikika kwa kulemera kwa nsanja yake komanso katundu wakunja.

Popeza amafunika kulumikizidwa mwamphamvu ndi konkire ndikuwaletsa kuti asatulutsidwe, mitundu yazitsulo za nangula zophatikizidwa za nsanja zotumizira zikuphatikizapo L-mtundu, J-mtundu, T-mtundu, I-mtundu, etc.

Mitundu yosiyanasiyana ya ma bawuti ophatikizidwa ali ndi ulusi wosiyanasiyana, kukula kwake ndi magwiridwe antchito, ndipo akuyenera kutsatira muyezo wa DL/T1236-2021.

Zofunika:

Zida zikuphatikizapo Q235B, 45 #, 35K, 40Cr, ndi zina zotero. Mwachitsanzo, ma bolts a 6.8J amtundu wa M12-M22 nthawi zambiri amapangidwa ndi zipangizo za 35K ndipo safuna kusinthasintha, pamene zipangizo zomwe zimagwiritsidwa ntchito nthawi zambiri za M24-M68 ndizosiyana. zopangidwa ndi 45 # zipangizo ndipo safuna kusinthasintha.

Maboti otumizira mphamvu a 8.8J a mawonekedwe a M12-M22 nthawi zambiri amapangidwa ndi zida za 35K, 45 #, ndi 40Cr ndipo amafunika kusinthidwa. Zida zomwe zimagwiritsidwa ntchito kwambiri 45 # ndi 40Cr za M24-M68 zimafunikira kusinthidwa. Zomwe zimafunikira pakupatsira mabawuti ndi mtedza ziyenera kutsata muyezo wa DL/T 248-2021.
