Li-bolts tse entsoeng ka tšepe e matla haholo, kapa li-bolts tse hlokang matla a maholo a ho laela pele, li ka bitsoa li-bolts tse matla haholo. Li-bolts tse matla tse matla li sebelisoa haholo bakeng sa ho hokahanya ha Bridges, rails, khatello e phahameng le lisebelisoa tsa khatello e phahameng haholo. Ho robeha ha liboutu tse joalo hangata ho robeha ha brittle. Bakeng sa li-bolts tse matla tse sebelisoang lisebelisoa tsa khatello ea ultrahigh, e le ho etsa bonnete ba ho tiisa setshelo, ho hlokahala prestress e kholo.
Phapang lipakeng tsa liboutu tse matla a phahameng le liboutu tse tloaelehileng:
Lisebelisoa tsa liboutu tse tloaelehileng li entsoe ka Q235 (ke hore A3).
Thepa ea liboutu tse matla haholo ke 35 # tšepe kapa lisebelisoa tse ling tsa boleng bo holimo, tse tšoaroang ka mocheso ka mor'a ho etsoa ho ntlafatsa matla.
Phapang pakeng tsa tse peli ke matla a thepa.
Ho tsoa ho lisebelisoa tse tala:
Li-bolts tse matla li entsoe ka thepa e matla e phahameng. The screw, nut le washer ea bolt e matla haholo e entsoe ka tšepe e matla e phahameng, e sebelisoang hangata 45 tšepe, 40 boron steel, 20 manganese titanium boron steel, 35CrMoA joalo-joalo. Li-bolts tse tloaelehileng hangata li entsoe ka tšepe ea Q235 (A3).
Ho tloha boemong ba matla:
Liboutu tse matla haholo li sebelisoa hangata lihlopheng tse peli tse matla tsa 8.8s le 10.9s, tseo 10.9 e leng bongata ba tsona. Matla a tloaelehileng a bolt a tlase, ka kakaretso ke 4.8, 5.6.
Ho ea ka pono ea litšoaneleho tsa matla: li-bolts tse matla tse matla li etsa hore ho be le tsitsipano pele le ho fetisetsa matla a ka ntle ka ho ferekana. Khokahano e tloaelehileng ea bolt e itšetlehile ka ho hanyetsa bolt shear le khatello ea lerako la lesoba ho fetisetsa matla a ho kuta, 'me boikaketsi bo hlahisoang ha ho tiisa linate bo nyane, tšusumetso ea eona e ka hlokomolohuoa, le bolt e matla e phahameng ho phaella ho matla a eona a phahameng a thepa, e boetse e sebetsa. boikaketsi bo boholo holim'a bolt, e le hore khatello ea extrusion pakeng tsa litho tse kopanyang, e le hore ho be le likhohlano tse ngata tsa perpendicular ho tataiso ea screw. Ho phaella moo, pretension, anti-slip coefficient le mofuta oa tšepe o ama ka ho toba matla a ho jara a bolts tse matla.
Ho ea ka litšobotsi tsa matla, e ka aroloa ka mofuta oa khatello le mofuta oa likhohlano. Mekhoa e 'meli ea ho bala e fapane. Tlhaloso e fokolang ea li-bolts tse matla haholo ke M12, e atisang ho sebelisoa M16 ~ M30, ts'ebetso ea li-bolts tse kholo ha e tsitsa, 'me e lokela ho sebelisoa ka hloko ha ho etsoa moralo.
Ho tloha ntlheng ea tšebeliso:
Khokahano ea bolt ea likarolo tse ka sehloohong tsa mohaho oa mohaho ka kakaretso o kopantsoe ke li-bolts tse matla haholo. Li-bolts tse tloaelehileng li ka sebelisoa hape, li-bolts tse matla haholo li ke ke tsa sebelisoa hape. Liboutu tse matla tse phahameng hangata li sebelisoa bakeng sa likhokahano tsa ka ho sa feleng.
