Amabhulothi enziwe ngensimbi enamandla amakhulu, noma amabhawodi adinga amandla amakhulu okulayisha kuqala, angabizwa ngokuthi amabhawodi anamandla amakhulu. Amabhawodi anamandla aphezulu asetshenziswa kabanzi ekuxhumeni amabhuloho, ojantshi, umfutho ophakeme kanye nemishini yokucindezela ephezulu kakhulu. Ukuphuka kwamabhawudi anjalo ngokuvamile kuwukuphuka okungama-brittle. Ukuze uthole ama-bolts anamandla aphezulu asetshenziselwa imishini yokucindezela i-ultrahigh, ukuze kuqinisekiswe ukuvala isitsha, i-prestress enkulu iyadingeka.
Umehluko phakathi kwamabhawodi anamandla amakhulu namabhawodi ajwayelekile:
Impahla yamabhawodi ajwayelekile yenziwe nge-Q235(okungukuthi A3).
Impahla yamabhawudo aqine kakhulu yinsimbi engu-35# noma ezinye izinto ezisezingeni eliphezulu, eziphathwa ngokushisa ngemva kokwenziwa ukuze kuthuthukiswe amandla.
Umehluko phakathi kwalokhu kokubili amandla ezinto ezibonakalayo.
Kusuka ezintweni ezingavuthiwe:
Amabhawodi anamandla aphezulu enziwe ngezinto ezinamandla kakhulu. Isikulufu, i-nati kanye newasha yebhawodi enamandla amakhulu zenziwe ngensimbi enamandla amakhulu, evamise ukusetshenziswa insimbi engu-45, insimbi engu-40 ye-boron, insimbi engu-20 ye-manganese titanium boron, 35CrMoA njalonjalo. Amabhawodi ajwayelekile ajwayele ukwenziwa ngensimbi ye-Q235(A3).
Kusukela kuleveli yamandla:
Amabhawodi anamandla aphezulu ajwayele ukusetshenziswa emabangeni amabili wamandla we-8.8s no-10.9s, angu-10.9 iningi lawo. Ibanga lamandla ebhawodi elijwayelekile liphansi, ngokuvamile lingu-4.8, 5.6.
Ngokombono wezici zamandla: amabhawodi anamandla aphezulu enza ukushuba kwangaphambi kwesikhathi futhi adlulise amandla angaphandle ngokungqubuzana. Uxhumo olujwayelekile lwebholithi luncike ekumelana ne-bolt shear kanye nokucindezela kodonga lwembobo ukuze kudluliselwe amandla okugunda, futhi ukuzenzisa okukhiqizwa lapho kuqiniswa i-nati kuncane, ithonya lalo lingashaywa indiva, kanye nebhawodi lamandla aphezulu ngaphezu kwamandla alo aphezulu, nawo ayasebenza. ukuzenzisa okukhulu kubhawodi, ukuze ingcindezi ye-extrusion phakathi kwamalungu axhumayo, ukuze kube nokungqubuzana okuningi kwe-perpendicular isiqondiso sesikulufu. Ukwengeza, i-pretension, i-anti-slip coefficient kanye nohlobo lwensimbi luthinta ngokuqondile umthamo wokuthwala wama-bolts aphezulu.
Ngokwezici zamandla, ingahlukaniswa ngohlobo lwengcindezi nohlobo lokungqubuzana. Izindlela zokubala ezimbili zihlukile. Ukucaciswa okuncane kwama-bolts anamandla aphezulu yi-M12, evame ukusetshenziswa i-M16~M30, ukusebenza kwama-bolts amakhulu kakhulu akuzinzile, futhi kufanele kusetshenziswe ngokucophelela ekuklanyweni.
Kusukela endaweni yokusetshenziswa:
Uxhumo lwe-bolt lwezingxenye eziyinhloko zesakhiwo sokwakha ngokuvamile luxhunywe ngama-bolts aphezulu. Amabhawodi ajwayelekile angasetshenziswa kabusha, amabhawodi anamandla aphezulu awakwazi ukuphinda asetshenziswe. Amabhawodi anamandla aphezulu ngokuvamile asetshenziselwa ukuxhumana unomphela.
