EN H-Shaped Steel Construction h Beam
I-H-beaminsimbi isetshenziswa kabanzi, ikakhulukazi esetshenziselwa: izinhlobonhlobo zezakhiwo zokwakha zomphakathi nezimboni; Izinhlobonhlobo zezitshalo zezimboni zesikhathi eside kanye nezakhiwo zesimanje eziphakeme kakhulu, ikakhulukazi ezindaweni ezinomsebenzi wokuzamazama komhlaba kanye nezimo zokusebenza ezishisa kakhulu; Amabhuloho amakhulu anamandla amakhulu okuthwala, ukuzinza okuhle kwe-cross-section kanye ne-span enkulu kuyadingeka; Imishini esindayo; Umgwaqo omkhulu; Amathambo omkhumbi; Ukusekela kwami; Ukwelashwa kwesisekelo kanye nobunjiniyela bedamu; Izingxenye zomshini ezihlukahlukene.
INQUBO YOKUKHIQISWA KOMKHIQIZO
I-flange yeHleyaiyahambisana noma icishe ihambisane ngaphakathi nangaphandle, futhi isiphetho se-flange sikwi-Engeli engakwesokudla, ngakho-ke ibizwa ngokuthi i-parallel flange I-steel. Ugqinsi lwewebhu yensimbi emise okwe-H incane kunaleyo ye-I-imishayo evamile enobude obufanayo bewebhu, futhi ububanzi be-flange bukhulu kunobu-I-imishayo evamile enobude obufanayo bewebhu, ngakho-ke ibizwa nangokuthi i-wide-rim I-imishayo. Kunqunywa ukuma, i-modulus yesigaba, umzuzu we-inertia namandla ahambisanayo we-H-beam ngokusobala kungcono kunaleyo ye-I-beam evamile enesisindo esisodwa esisodwa. Isetshenziselwa izidingo ezahlukene zesakhiwo sensimbi, kungakhathaliseki ukuthi ingaphansi kwe-torque egobayo, umthwalo wengcindezi, umthwalo we-eccentric ubonisa ukusebenza kwawo okuphakeme, ungathuthukisa kakhulu umthamo wokuthwala kune-I-steel evamile, ukonga insimbi 10% ~ 40%. Insimbi emise okwe-H ine-flange ebanzi, iwebhu encane, imininingwane eminingi, kanye nokusetshenziswa okuguquguqukayo, okungasindisa u-15% kuya ku-20% wensimbi ezakhiweni ezihlukahlukene ze-truss. Ngenxa yokuthi i-flange yayo ihambisana ngaphakathi nangaphandle, futhi isiphetho sonqenqema sise-Angle elungile, kulula ukuhlanganisa nokuhlanganisa izingxenye ezihlukahlukene, ezingasindisa cishe u-25% we-welding kanye nomthwalo we-riveting, futhi ingasheshisa kakhulu isivinini sokwakha. wephrojekthi futhi unciphise isikhathi sokwakha.

IZICI
Kukhona imininingwane eminingi yomkhiqizo weI-H-beam, kanye nezindlela zokuhlukanisa zimi kanje.(1) Ngokobubanzi be-flange bomkhiqizo, ihlukaniswe yaba i-flange ebanzi, i-flange emaphakathi kanye ne-flange ewumngcingo engu-H. bukhulu noma bulingana nobude bewebhu H. Ububanzi be-flange B bensimbi ewumngcingo emise okwe-H bulingana nohhafu wobude H bepuleti lewebhu.(2) Ngokuhambisana nokusetshenziswa komkhiqizo, i ihlukaniswe ngensimbi yohlobo lwe-H, ikholomu yensimbi yohlobo H, inqwaba yensimbi yohlobo lwe-H kanye nensimbi yohlobo lwe-H ene-flange ewugqinsi ngokwedlulele. Kwesinye isikhathi insimbi yesiteshi somlenze ohambisanayo kanye ne-parallel flange T-beam steel nazo zifakiwe ebangeni. we-H-imishayo. Ngokuvamile, insimbi ye-flange encane ye-H-beam isetshenziswa njenge-beam kanye ne-wide flange H-beam steel isetshenziswa njengekholomu. Ngakho-ke, yaziwa nangokuthi i-beam H-beam steel kanye nekholomu ye-H-beam steel. (3) Ngokwendlela yokukhiqiza, ihlukaniswe yaba insimbi eshiselwe i-H-beam kanye nensimbi egoqelwe ye-H. (4) Ngokwezicaciso zesayizi zihlukaniswe zibe yinsimbi enkulu, ephakathi nendawo encane efana no-H. Ngokuvamile, imikhiqizo enobude bewebhu H ngaphezu kuka-700mm ibizwa ngokuthi enkulu, i-300 ~ 700mm ibizwa ngokuthi i-medium, futhi leyo engaphansi kuka-300mm ibizwa ngokuthi encane. Ekupheleni kuka-1990, ubude bewebhu be-H-beam obukhulu kunawo wonke emhlabeni obungu-1200mm, ububanzi obunobubanzi obungu-530mm.
UKUHLOLWA KOMKHIQIZO
Izidingo zokuhlolwa kwensimbi okumise okwe-H ikakhulukazi zifaka izici ezilandelayo:
Ikhwalithi yokubukeka: Ikhwalithi yokubukeka yensimbi emise okwe-H kufanele ihambisane nezindinganiso ezifanele kanye nezidingo zoku-oda. Ubuso kufanele busheleleke futhi bube bushelelezi, ngaphandle kwama-dents asobala, imihuzuko, ukugqwala nokunye ukukhubazeka.
Ubukhulu beJiyomethri: Ubude, ububanzi, ubude, ukujiya kwewebhu, ukujiya kwe-flange nobunye ubukhulu bensimbi emise okwe-H kufanele kuhambisane nezindinganiso ezifanele kanye nezidingo zoku-oda.
I-Curvature: I-curvature yensimbi emise okwe-H kufanele ihambisane nezindinganiso ezifanele kanye nezidingo zoku-oda. Ingatholwa ngokulinganisa ukuthi izindiza ezikuzo zombili iziphetho zensimbi emise okwe-H ziyahambisana noma zisebenzisa imitha egobayo.
I-twist: I-twist yensimbi emise okwe-H kufanele ihambisane nezindinganiso ezifanele kanye nezidingo zoku-oda. Ingatholwa ngokulinganisa ukuthi uhlangothi lwensimbi emise okwe-H luqondile noma lunemitha yokusonta.
Ukuchezuka kwesisindo: Isisindo sensimbi emise okwe-H kufanele sihambisane nezindinganiso ezifanele kanye nezidingo zoku-oda. Ukuchezuka kwesisindo kungatholwa ngokukala.
Ukwakheka kwamakhemikhali: Uma insimbi emise okwe-H idinga ukushiselwa noma ukucutshungulwa ngenye indlela, ukwakheka kwayo kwamakhemikhali kufanele kuhambisane nezindinganiso ezifanele kanye nezidingo zoku-oda.
Izici zemishini: Izakhiwo zemishini yensimbi emise okwe-H kufanele ihambisane nezindinganiso ezifanele kanye nezidingo zoku-oda, okuhlanganisa amandla aqinile, iphuzu lesivuno, ukwelula nezinye izinkomba.
Ukuhlola okungabhubhisi: Uma insimbi emise okwe-H idinga ukuhlolwa okungabhubhisi, kufanele ihlolwe ngokuhambisana nezindinganiso ezifanele kanye nezidingo zoku-oda ukuze kuqinisekiswe ukuthi ikhwalithi yayo yangaphakathi yinhle.
Ukupakisha nokumaka: Ukupakishwa nokumaka kwensimbi emise okwe-H kufanele kuhambisane nezindinganiso ezifanele kanye nezidingo zoku-oda ukuze kube lula ukuhamba nokugcinwa.
Ngamafuphi, izidingo ezingenhla kufanele zicatshangelwe ngokugcwele lapho kuhlolwa insimbi emise okwe-H ukuze kuqinisekiswe ukuthi ikhwalithi yayo ihlangabezana nezindinganiso ezifanele kanye nezidingo zoku-oda, nokuhlinzeka abasebenzisi ngemikhiqizo yensimbi emise okwe-H engcono kakhulu.
Isicelo
OkuvamileI-H-beamizinto zensimbi zihlanganisa i-Q235B, i-SM490, i-SS400, i-Q345 ne-Q345B. Ukwakheka kwamakhemikhali kanye nezakhiwo zemishini yalezi zinto zihlukile, ngakho-ke lapho ukhetha ukusetshenziswa kwe-H-beam, kuyadingeka ukukhetha izinto ezifanele ngokuvumelana nesimo esithile.
UKUPAKA KANYE NOKUTHUMELA
Ukupakishwa nokuvikela:
Ukupakisha kudlala indima ebalulekile ekuvikeleni ikhwalithi ye-ASTM A36Hleyainsimbi ngesikhathi sokuthutha nokugcinwa. Izinto ezisetshenziswayo kufanele zigoqwe ngokuvikelekile, kusetshenziswa amabhande noma amabhande aphezulu ukuze kuvinjelwe ukunyakaza kanye nokulimala okungenzeka. Ukwengeza, kufanele kuthathwe izinyathelo zokuvikela insimbi ekuchayekeni kumswakama, uthuli, nezinye izici zemvelo. Ukugoqa izinqwaba ngezinto ezimelana nesimo sezulu, njengepulasitiki noma indwangu engangeni manzi, kusiza ukuvikela ekugqwaleni nokugqwala.
