Amabhawodi amise okwe-U ayizingxenye ezingezona ezijwayelekile ezivame ukusetshenziselwa ukulungisa amashubhu njengamapayipi amanzi noma iziphethu zeshidi ezifana nemithombo yamaqabunga emoto. Ngenxa yokuma kwayo okumise okwe-U, ingahlanganiswa namantongomane, ngakho-ke yaziwa nangokuthi amabhawodi amise okwe-U noma amabhawodi okugibela.
Izimo eziyinhloko zamabhawodi amise okwe-U zihlanganisa i-semicircle, i-engeli yesokudla yesikwele, unxantathu, unxantathu oblique nokunye. Amabhawodi amise okwe-U anezici ezihlukile zezinto ezibonakalayo, ubude, ububanzi namandla amamaki angakhethwa ngokuya ngendawo yokusetshenziswa nezidingo ezahlukahlukene.
Unezinhlobonhlobo zokusetshenziswa, ikakhulukazi ezisetshenziswa ekwakheni nasekufakeni, ukuxhuma izingxenye zemishini, izimoto nemikhumbi, amabhuloho, imigudu, izitimela kanye neminye imikhakha. Emalolini, ama-U-bolt asetshenziselwa ukuzinzisa indawo yemoto nohlaka. Isibonelo, intwasahlobo yeqabunga ixhunywe ngamabhawodi amise okwe-U.
Ukukhetha ibanga le-bolt.
Amamaki e-bolt ngokuvamile ahlukaniswe abe izinhlobo ezimbili: amabhawodi anamandla aphezulu namabhawodi ajwayelekile. Lapho ukhetha ibanga le-bolt, lidinga ukucatshangelwa ngokuya ngendawo yesicelo, izici zamandla, izinto zokusetshenziswa nokunye.
1. Ngokombono wezinto ezingavuthiwe: amabhawodi anamandla aphezulu enziwe ngezinto eziqinile, njengensimbi engama-45 #, insimbi engama-40 ye-boron, insimbi engama-20 ye-manganese titanium boron. Amabhawodi ajwayelekile enziwa ngensimbi ye-Q235.
ezimbili.. Ngokwezinga lamandla, amabhawodi anamandla aphezulu asetshenziswa kakhulu ama-8.8s kanye nama-10.9s, okuyi-10.9S okuyiwona asetshenziswa kakhulu. Amabanga wamandla amabhawodi ajwayelekile angu-4.4, 4.8, 5.6 no-8.8.
3. Kusukela endaweni yokubuka izici zemishini: ama-bolts anamandla aphezulu asebenzisa ukucindezeleka kwangaphambili nokudlulisa amandla angaphandle ngokungqubuzana. Ngakolunye uhlangothi, ukuxhuma okujwayelekile kwe-bolt kuncike ekuphikiseni kwe-shear kwenduku ye-bolt kanye nokucindezela odongeni lwembobo ukuze kudluliselwe amandla okugunda, futhi ukucindezeleka kwangaphambili kuncane kakhulu lapho kuqinisa i-nut. Ngakho-ke, izici zemishini zidinga ukucatshangelwa kuhlelo lokusebenza.
4. Kusukela ekubukeni kokusetshenziswa: ukuxhuma okuboshiwe kwezingxenye eziyinhloko zesakhiwo sokwakha ngokuvamile kuxhunywe ngama-bolts aphezulu. Amabhawodi ajwayelekile angasetshenziswa kabusha, kuyilapho amabhawudi anamandla amakhulu engakwazi ukuphinda asetshenziswe futhi ngokuvamile asetshenziselwa ukuxhuma unomphela.
Ngamafuphi, lapho sikhetha ukucaciswa kanye nebanga lebhawodi lebhawodi emise okwe-U, kufanele sicabangele impahla, izinga lamandla kanye nezici zokucindezeleka zebhawodi ngokuya ngesidingo sangempela kanye nendawo esetshenziswayo, bese sikhetha umkhiqizo ofanele ukuzuza umphumela webhawodi. ukuphepha, ukuzinza nokuthembeka.
