Qhov dav flange tsim txhawb nqa hnyav pallet khib loads thiab ntev spans, tshem tawm cov kab nruab nrab kom ua kom qhov chaw cia kom zoo. Kub dov ua kom qhov sib xws ntawm qhov sib xws rau kev sib dhos modular, ua kom lub sijhawm siv sijhawm ntev li 30%. Nrog zoo weldability thiab ductility (elongation Ntau dua los yog sib npaug li 21%), nws ua tau raws li lub ntiaj teb prefabrication qauv, ntsuas kev ua tau zoo thiab tus nqi -kev ua tau zoo rau kev ceev- taug qab cov khoom siv hauv tsev.
H-Beam Steel ASTM A992 Q355 S275jr 150 × 150 300 × 150mm rau Hnyav- Lub Luag Haujlwm Txhawb Nqa
Qhov hnyav -lub luag haujlwm H beam ua keASTM A992 (345 MPa tawm los), Q355 (355MPa yield), thiab S275jr (275MPa yield) qib, nrog cov tub ntxhais loj loj 150 × 150mm thiab 300 × 150mm, ntxiv rau qhov ntau ntawm 100 × 50mm txog 600 × 200mm thiab ntev 6-14m. Tsim los rau kev txhawb nqa crane, kev siv tshuab hauv paus, thiab siab -load rhiav thav duab, nws muab lub zog tensile 450-650MPa thiab zoo heev qaug zog. Kub dov txhim kho cov khoom tawv tawv, thaum qhov ua kom zoo H-puab faib dynamic loads sib npaug, tiv thaiv kev ua haujlwm tsis zoo nyob rau hauv kev ntxhov siab. Ua raws li ASTM thiab GB / T cov qauv, nws muaj kev sib txuas zoo dua thiab ua haujlwm tau zoo, tso cai rau kev txiav thiab drilling rau kev teeb tsa. Tus nqi- ua tau zoo thiab ruaj khov, nws yog qhov kev xaiv zoo tshaj plaws rau cov haujlwm hnyav- kev lag luam kev tsim kho.
Q355b Kub Rolled H-Section Steel 300 × 300 500 × 500mm Tus Qauv Beam rau Choj Infrastructure
Engineered rau choj thiab kev loj tej yaam num, Q355b H-section beam nta core square sizes 300 × 300mm thiab 500 × 500mm, web thickness 10-35mm, flange thickness 12-55mm, thiab ntev 6-14m. Nrog lub zog tawm los ntawm 355MPa thiab zoo heev qis- qhov kub thiab txias cuam tshuam, nws tiv taus cov tsheb thauj khoom hnyav thiab huab cua hnyav. Kub dov ua kom cov qauv zoo li qub thiab qhov tseeb qhov tseeb, qhov tseem ceeb rau kev txhawb nqa choj thiab piers. Tus ntoo khaub lig symmetrical-section optimizes kev nyuaj siab faib, tiv thaiv dabtsi yog khoov thiab torsion nyob rau hauv siab heev. Optional galvanizing muab kev tiv thaiv corrosion nyob rau hauv ntug dej hiav txwv ib puag ncig, ncua kev pab cuam lub neej mus rau ntau tshaj 25 xyoo. Ua raws li GB / T 1591 thiab ASTM cov qauv, nws yog ib qho kev txhim khu kev qha rau cov haujlwm loj -scale engineering engineering.
Zoo siab ASTM A36 S355jr HEA / IPE H Beam Kub Rolled Galvanized rau Kev Lag Luam Hlau Qauv
Qhov kev lag luam no -qib H beam integratesASTM A36 (250 MPa tawm los)thiab S355jr (355MPa yield) qib, npog HEA / IPE European seem nrog qhov ntau thiab tsawg 180 × 94mm txog 700 × 250mm thiab ntev 6-12m. Kub-dip galvanizing ua kom muaj kev tiv thaiv corrosion rau cov khw muag khoom thav ntawv, chaw ua haujlwm txhawb nqa, thiab cov khw muag khoom steel qauv. Qhov dav flange tsim ua kom qhov chaw sab hauv los ntawm kev txhawb nqa ntev ntev yam tsis muaj kab nruab nrab. Kub dov muab cov nplaim du thiab zoo weldability, txo cov nqi ua haujlwm thib ob. Nrog lub zog sib npaug- rau- qhov hnyav piv, nws absorbs seismic rog los txhim kho kev ruaj ntseg hauv tsev. Tus nqi sib tw rau kev txiav txim ntau, nws ua tau raws li cov qauv kev lag luam thoob ntiaj teb kev tsim kho, ntsuas kev ua tau zoo, kev zoo nkauj, thiab tus nqi- ua haujlwm tau zoo.
