Maboti ooneka ngati U ndi mbali zosagwirizana ndi zomwe nthawi zambiri zimagwiritsidwa ntchito kukonza machubu monga mapaipi amadzi kapena akasupe amasamba monga akasupe amasamba agalimoto. Chifukwa cha mawonekedwe ake a U, amatha kuphatikizidwa ndi mtedza, choncho amadziwikanso kuti ma bolts opangidwa ndi U kapena ma bolts okwera.
Maonekedwe akuluakulu a ma bolt opangidwa ndi U amaphatikizapo semicircle, square right angle, triangle, oblique triangle ndi zina zotero. Maboti ooneka ngati U okhala ndi zinthu zosiyanasiyana, kutalika, m'mimba mwake ndi magiredi amphamvu amatha kusankhidwa malinga ndi malo osiyanasiyana ogwiritsira ntchito komanso zofunikira.
Iye ali osiyanasiyana ntchito, makamaka ntchito yomanga ndi unsembe, makina mbali kugwirizana, magalimoto ndi zombo, milatho, tunnel, njanji ndi madera ena. Pamagalimoto, ma U-bolts amagwiritsidwa ntchito kuti akhazikitse malo agalimoto ndi chimango. Mwachitsanzo, kasupe wa masamba amalumikizidwa ndi mabawuti ooneka ngati U.
Kusankha kalasi ya bolt.
Magulu a bolt nthawi zambiri amagawidwa m'mitundu iwiri: mabawuti amphamvu kwambiri ndi mabawuti wamba. Posankha kalasi ya bawuti, iyenera kuganiziridwa molingana ndi malo ogwiritsira ntchito, mawonekedwe amphamvu, zida zopangira ndi zina zotero.
1. Kuchokera kuzinthu zopangira zipangizo: ma bolts amphamvu kwambiri amapangidwa ndi zipangizo zamphamvu kwambiri, monga 45 # zitsulo, 40 zitsulo za boron, 20 manganese titanium boron zitsulo. Maboti wamba nthawi zambiri amapangidwa ndi chitsulo cha Q235.
awiri.. Pankhani ya kalasi yamphamvu, mabawuti omwe amagwiritsidwa ntchito kwambiri ndi 8.8s ndi 10.9s, pomwe 10.9S ndi omwe amagwiritsidwa ntchito kwambiri. Mphamvu zama bawuti wamba ndi 4.4, 4.8, 5.6 ndi 8.8.
3. Kuchokera pamalingaliro a machitidwe amakina: ma bolts apamwamba amagwiritsira ntchito kuthamanga kusanachitike ndikusamutsa mphamvu yakunja ndi kukangana. Kumbali inayi, kugwirizana kwa bawuti wamba kumadalira kukana kukameta ubweya wa ndodo ya bawuti ndi kukanikiza pakhoma la dzenje kusamutsa mphamvu yakumeta ubweya, ndipo kukangana koyambirira kumakhala kochepa kwambiri pakumangitsa nati. Chifukwa chake, mawonekedwe amakina ayenera kuganiziridwa mukugwiritsa ntchito.
4. Kuchokera kumalo ogwiritsira ntchito: kugwirizanitsa kwazitsulo zamagulu akuluakulu a zomangamanga nthawi zambiri kumagwirizanitsidwa ndi ma bolts amphamvu kwambiri. Maboti wamba amatha kugwiritsidwanso ntchito, pomwe mabawuti amphamvu kwambiri sangathe kugwiritsidwanso ntchito ndipo nthawi zambiri amagwiritsidwa ntchito polumikizana kokhazikika.
Mwachidule, posankha mtundu wa bawuti wooneka ngati U, posankha bawuti yoboola pakati, tiyenera kuganizira zakuthupi, giredi lamphamvu komanso kupsinjika kwa bawuti molingana ndi kufunikira kwenikweni ndikugwiritsa ntchito chilengedwe, ndikusankha chinthu choyenera kuti tikwaniritse zotsatira zake. chitetezo, kukhazikika ndi kudalirika.
