TXHEEJ TXHEEM TXOG KEV TSIM KHOOM
Lub flange ntawmH beamyog sib luag lossis yuav luag sib luag ntawm sab hauv thiab sab nraud, thiab qhov kawg ntawm lub flange yog nyob rau ntawm lub kaum sab xis, yog li nws hu ua parallel flange I-steel. Lub thickness ntawm lub web ntawm H-zoo li hlau yog me dua li ntawm cov I-beams ib txwm muaj nrog tib qhov siab ntawm lub web, thiab qhov dav ntawm lub flange yog loj dua li ntawm I-beams ib txwm muaj nrog tib qhov siab ntawm lub web, yog li nws kuj hu ua dav-rim I-beams. Txiav txim siab los ntawm cov duab, qhov seem modulus, lub sijhawm ntawm inertia thiab lub zog sib xws ntawm H-beam yog qhov zoo dua li ntawm I-beam ib txwm muaj nrog tib qhov hnyav. Siv rau hauv cov kev xav tau sib txawv ntawm cov qauv hlau, txawm tias nws nyob rau hauv kev khoov torque, lub nra hnyav siab, eccentric load qhia nws cov kev ua tau zoo tshaj plaws, tuaj yeem txhim kho lub peev xwm dais ntau dua li I-steel ib txwm muaj, txuag hlau 10% ~ 40%. H-zoo li hlau muaj flange dav, lub web nyias, ntau yam specifications, thiab kev siv yooj ywm, uas tuaj yeem txuag 15% txog 20% ntawm cov hlau hauv ntau yam qauv truss. Vim tias nws cov flange sib luag sab hauv thiab sab nraud, thiab qhov kawg ntawm ntug yog nyob rau ntawm lub kaum sab xis, nws yooj yim rau kev sib sau ua ke thiab sib xyaw ua ke rau hauv ntau yam khoom, uas tuaj yeem txuag tau li 25% ntawm kev vuam thiab riveting workload, thiab tuaj yeem ua kom ceev nrooj ntawm qhov project thiab luv lub sijhawm tsim kho.

NTA
Muaj ntau yam khoom specifications ntawmH-beam, thiab cov txheej txheem kev faib tawm yog raws li nram no. (1) Raws li qhov dav ntawm cov khoom, nws tau muab faib ua flange dav, flange nruab nrab thiab flange nqaim H-beam. Qhov dav flange B ntawm flange dav thiab flange nruab nrab H-beam yog ntau dua lossis sib npaug rau qhov siab ntawm lub vev xaib H. Qhov dav flange B ntawm cov hlau flange nqaim H-puab yog sib npaug li ib nrab ntawm qhov siab H ntawm lub vev xaib phaj. (2) Raws li kev siv cov khoom, nws tau muab faib ua H-hom hlau beam, H-hom hlau kem, H-hom hlau pawg thiab H-hom hlau beam nrog flange tuab heev. Qee zaum cov hlau channel ceg sib luag thiab cov hlau flange sib luag T-beam kuj suav nrog hauv ntau yam ntawm H-beams. Feem ntau, flange nqaim H-beam hlau yog siv ua beam thiab flange dav H-beam hlau yog siv ua kem. Yog li ntawd, nws kuj hu ua beam H-beam hlau thiab kem H-beam hlau. (3) Raws li txoj kev tsim khoom, nws tau muab faib ua welded H-beam hlau thiab dov H-beam hlau. (4) Raws li qhov loj me, cov hlau H-puab raug muab faib ua cov hlau loj, nruab nrab thiab me. Feem ntau, cov khoom uas muaj qhov siab ntawm lub vev xaib H siab tshaj 700 hli hu ua loj, 300 ~ 700 hli hu ua nruab nrab, thiab cov uas tsawg dua 300 hli hu ua me. Thaum kawg ntawm xyoo 1990, lub vev xaib H-beam loj tshaj plaws hauv ntiaj teb yog 1200 hli, thiab qhov dav ntawm flange yog 530 hli.
KEV TSHAWB XYUAS KHOOM
Cov kev cai rau kev tshuaj xyuas hlau H-zoo li feem ntau suav nrog cov hauv qab no:
Qhov zoo ntawm cov hlau H-puab yuav tsum ua raws li cov qauv thiab cov kev cai xaj. Qhov saum npoo yuav tsum du thiab tiaj tus, tsis muaj qhov pom tseeb, khawb, xeb thiab lwm yam tsis zoo.
Qhov ntev ntawm cov duab geometric: Qhov ntev, dav, qhov siab, qhov tuab ntawm lub web, qhov tuab ntawm flange thiab lwm qhov ntev ntawm cov hlau H-puab yuav tsum ua raws li cov qauv thiab cov kev cai xaj.
Kev nkhaus: Qhov nkhaus ntawm cov hlau H-puab yuav tsum ua raws li cov qauv thiab cov kev cai txiav txim. Nws tuaj yeem kuaj pom los ntawm kev ntsuas seb cov dav hlau ntawm ob qho kawg ntawm cov hlau H-puab puas sib luag lossis siv lub ntsuas khoov.
Twist: Qhov twist ntawm cov hlau H-puab yuav tsum ua raws li cov qauv thiab cov kev cai txiav txim. Nws tuaj yeem ntes tau los ntawm kev ntsuas seb sab ntawm cov hlau H-puab yog ntsug lossis nrog lub ntsuas twist.
Qhov hnyav sib txawv: Qhov hnyav ntawm cov hlau H-puab yuav tsum ua raws li cov qauv thiab cov kev cai xaj khoom. Qhov hnyav sib txawv tuaj yeem pom los ntawm kev ntsuas qhov hnyav.
Cov tshuaj lom neeg muaj pes tsawg leeg: Yog tias cov hlau H-puab xav tau welded lossis ua lwm yam, nws cov tshuaj lom neeg muaj pes tsawg leeg yuav tsum ua raws li cov qauv thiab cov kev cai xaj.
Cov khoom siv kho tshuab: Cov khoom siv kho tshuab ntawm H-puab hlau yuav tsum ua raws li cov qauv thiab cov kev cai xaj, suav nrog lub zog tensile, cov ntsiab lus tawm, elongation thiab lwm yam cim.
