Ukuthembeka ukuxhasa izakhiwo ziya kubonelela I-msebe

I- imiqadi metal zisetyenziswa phantse zonke esakhiweni mihla, zombini mveliso kunye yoluntu. Ekubeni bekukubi ethile iphantsi kakhulu, bona babe nomthamo umthwalo eliphezulu kuka ukuba babele ngempumelelo umthwalo izakhiwo ezixhasayo. Ezi zenziwa iqengqwa iimveliso yesinyithi (iimveliso zesinyithi, kabini-tee umqadi eshushu-liqengqiwe) okanye indlela welding. Le somhlathi ke H-ezimile uyilo udonga kunye flanges ezimbini nkqo kuyo. Komele kungenzeka ube icala lwangaphakathi yokukhulisa olongezelelweyo. iimveliso ezifana zilufanele ukuqinisa kunye emigodini yokukhulisa (series C kunye ithambeka ka-16%), kunye imisiwe iindlela ukuyinyusa (uthotho M kunye ethambekeni ka-12%).

Asongwe beam kabini-tee nayo ebizwa I-msebe. Izicelo eziphambili zezi mveliso yesinyithi - imigangatho zokwakha, izakhiwo ibhulorho, indlela imisiwe, iintsika kunye imiqolo. Kuxhomekeka ngenjongo yokuba izakhiwo zakhiwe, steelI I-umqadi anokuhlenga-hlengiswa ukwenzela nomthwalo ezahlukeneyo. Ngokwemo, I-amacandelo kunye nodonga ezahlukeneyo Ebubanzini ezishelfini, komele ime iinkalo (ubuso babo ngaphakathi inokuba parallel okanye kwithambeka). Ixabiso kwakhona linokukhetha indlela yokuvelisa, injongo kunye nobugcisa iparameters.

beam Steel kabini-tee singenziwa ngokungqinelana nemigangatho karhulumente (GOST 8239 - 89, Standard 19425 - 74, GOST 26020 - 83 kunye nabanye), kunye ngokungqinelana iinkcukacha umenzi. Kwimeko izinto kwabadlali carbon zokwakha ezikumgangatho oqhelekileyo. Esi sakhiwo metal ibe umqadi kabini-tee eyenziwe nge welding zokwakha ephantsi-ingxubevange izakhiwo welding.

Zininzi iintlobo eyodwa I-neyophahla kunye ngaxeshanye ubuso ezishelifini: yesiqhelo (B), kwikholam (K), elive- (W), Eqhelekileyo (WO), uluhlu olongezelelweyo (L kunye LH). Wenza beam kabini-tee kwimigangatho, ngokuxhomekeke njongo, kukho ubude ukusuka-4 ukuya ku-12 m (ngokuvumelana ngumthengi - ukuya kuma-24 m). Ingaba phezulu (A) okanye oqhelekileyo (B) ukuchana lothuli.

steel welding I-echweliweyo zenziwa oxwebhu metal ngokwamanqanaba eziliqela. Okokuqala wabumba preform ubungakanani ezifunwa ukunqunqa ngokummisela, uthabathela kumntwana otyhidiweyo, uhlangothi lwayo ukusilwa. Vuna strip crane zigqithiselwe ibhanti yokuthutha, crimped kwaye umphunga ufakelo oluzenzekelayo. Ngaphezu koko, imveliso liqengqwa kwinkampu esikhethekileyo kususwe iziphene kunokwenzeka yaye alungiswa ngokuthi nangembabala sisityalo ngenxa yokubulala. Umgangatho welding I-beam kufuneka ihlangabezane neemfuno GOST 23118-99 kunye GOST 26020-83 (okanye parameters zayo kuxoxwa kwangaphambili kunye umthengi).

I-echweliweyo bakwazi ukuya kwi-30% ukuququzelela izakhiwo umthwalo-ethwele xa kuthelekiswa kunye nemilenze ezishushu. ukuzimisela lokuqala neyophahla ubungakanani kakhulu ukucutha ubuninzi benkunkuma. Bobubi ziquka sesichengeni I-neyophahla umhlwa ukuba akukho ukutyabeka zokuzikhusela, yaye imfuno izixhobo ezizodwa, ngaphandle apho ke asikwazi mayixhonywe.
