Twese tuzi ko bolts yitwa umuceri winganda. Waba uzi gutondekanya ibisanzwe bikoreshwa mumashanyarazi? Muri rusange, umunara woherejwe ushyirwa mubyiciro ukurikije imiterere, urwego rwimbaraga, kuvura hejuru, intego yo guhuza, ibikoresho, nibindi.

Imiterere y'umutwe:

Ukurikije imiterere yumutwe wa bolt, ibisanzwe bikoreshwa muminara yoherejwe ahanini ni imitwe ya mpande esheshatu.

Uburyo bwo kuvura hejuru:

Kubera ko iminara isanzwe ikwirakwizwa nk'iminara y'ibyuma hamwe n'iminara y'ibyuma bishyushye bishyushye kugira ngo byuzuze ibisabwa nko kurwanya ingaruka no kurwanya ruswa, bishyirwa mu byuma bishyushya imashanyarazi.

Muri byo, ibyuma bya ankor nibyingenzi bihuza ibice kugirango umutekano wamashanyarazi. Uburyo bwabo bwo kuvura hejuru burimo igice gishyushye-cyogusunika hamwe na hot-dip galvanizing igice cyumutwe.

Imbaraga zo mu rwego:

Umuyoboro wogukwirakwiza ugabanijwemo ibyiciro bine: 4.8J, 6.8J, 8.8J na 10.9J, muribyo 6.8J na 8.8J bolts zikoreshwa cyane.

Intego yo guhuza:

Igabanyijemo amasano asanzwe kandi yashyizwemo. Imashini ya Anchor yashyizwemo ibice byumuriro wamashanyarazi ， kandi mubisanzwe bikoreshwa mugukosora umunara kugirango habeho gushyigikirwa kuburemere bwumunara hamwe nuburemere bwo hanze.

Kubera ko bakeneye guhuzwa neza na beto no kubarinda gukururwa, ubwoko bwimashini zometseho iminara yoherejwe harimo L-ubwoko, J-bwoko, T-ubwoko, I-bwoko, nibindi.

Ubwoko butandukanye bwinjizwamo inanga zifite imigozi itandukanye, ingano ninzego zimikorere, kandi igomba kubahiriza DL / T1236-2021.

Ibikoresho:

Ibikoresho birimo Q235B, 45 #, 35K, 40Cr, nibindi. bikozwe muri 45 # ibikoresho kandi ntibisaba modulation.

Amashanyarazi ya 8.8J yoherejwe na M12-M22 asanzwe akozwe mubikoresho 35K, 45 #, na 40Cr kandi bigomba guhindurwa. Bikunze gukoreshwa 45 # na 40Cr ibikoresho bya M24-M68 bigomba guhinduka. Ibikoresho byihariye bisabwa kugirango umunara woherejwe hamwe nimbuto bigomba kubahiriza DL / T 248-2021.
