Cov txheej txheem steel welded lub thawv beam yog siab - cov tswv cuab kev ua haujlwm tau tsim los ntawm plaub lub phaj hlau rau hauv ib qho kaw, lub voj voos, muab qhov hnyav torsional rigidity thiab sib npaug lub zog hauv ob lub axes. Vim tias qhov kaw qhov profile tsim ib txoj hauv kev txuas mus ntxiv nyob ib puag ncig nws thaj tsam, nws qhov torsional nruj yog 50-100 npaug ntawm qhov sib npaug qhib seem thiab nws tiv thaiv sab nraud-torsional buckling inherently, yog li cov engineers tuaj yeem txuas ntxiv thiab tsim siab dua, ntau dua thav duab hauv qab hnyav thiab eccentric loads.
Peb tsim lub thawv kab teeb thiab kab los ntawm Q235B / Q355B, S235JR / S355JR lossis A36 / A572 Gr.50, nrog rau sab hauv diaphragms ntawm qhov sib nrug ntawm koj qhov kev xav tau thiab kaum seams los ntawm SAW hauv qab WPS / PQR. Cov tswv cuab yog Tekla- nthuav dav, qhov loj me- kuaj xyuas, qhov tseem ceeb welds UT/RT Qib I/II, tom qab ntawd Sa2.5 txhaj tshuaj- blasted thiab pleev xim los yog galvanized.

Vim li cas No Welded Box Beam?
Heev torsional rigidity- kaw lub voj muaj torque nyob ib ncig ntawm lub perimeter, tiv thaiv twist uas ua tsis tau ib qho qhib seem.
Balanced biaxial zog- sib npaug ob-axis txhav haum rau ob-txoj kev dabtsi yog khoov thiab slender siab- cov tswv cuab sawv.
Tiv thaiv lateral -torsional buckling- ruaj khov nyob rau hauv hnyav eccentric loads, ntev spans tsis ntxiv bracing.
Internal diaphragms & lub zos stability- qhov sib piv thiab qhov sib nrug tau teeb tsa rau koj qhov kev thauj khoom los tiv thaiv phaj buckling.
SAW + WPS / PQR weld zoo- kaum seams SAW, tseem ceeb welds UT/RT Qib I/II.
Tekla nthuav dav & erection npaj- BIM- raug nrog cov duab kos thiab xaiv thib peb - kev tshuaj xyuas tog.
Kev siv ntawm Box Beams
Bridge Engineering- lub ntsiab load-cov kabmob girders rau ntev- txuas txuas txuas ntxiv thiab kev loj hlob, qhov siab torsional rigidity tswj eccentric tsheb / cua loads.
Hnyav-Lub luag haujlwm Crane Runway Beams- khiav kab teeb rau siab - muaj peev xwm overhead cranes nyob rau hauv steel mills thiab hnyav manufacturing, resisting dynamic lateral loads thiab sway.
Loj -Span Public Buildings- dav dav - ncua lub ru tsev thav duab thiab hloov cov qauv hauv tshav dav hlau thiab chaw ntau pob.
High-Rise Construction- thawj cov tswv cuab kab rov tav, hloov girders thiab kaum kab hauv skyscrapers.
Hnyav Khoom Txhawb & Machinery- txhawb nqa ncej rau crushers, cov ntxaij vab tshaus thiab lub zog- cog boilers ntawm mining thiab lub zog platforms.
Peb Customization Service

FAQ:
Vim li cas thiaj xaiv lub thawv beam hla qhov qhib H/I-section ntawm tib qhov hnyav?
Lub thawv kaw lub voj voog thauj khoom nyob ib puag ncig - torsional tawv feem ntau 50–100 × qhib H - nrog lub zog biaxial sib npaug, cia koj tsim siab dua, slimmer thav ntawv yam tsis muaj lateral -torsional buckling rau ntev spans, nkhaus cov tswv cuab thiab torsionally loaded ntsiab.
Dab tsi seem qhov ntev thiab qib steel koj tuaj yeem tsim tau?
Txhua qhov kev thauj mus los ntev tso cai; web / flange widths thiab thicknesses me me rau seem modulus nrog sab hauv diaphragms raws li xav tau; qib Q235B/Q355B, S235JR/S355JR, A36/A572 Gr.50, siab -lub zog ntawm kev thov.
Yuav ua li cas yog plaub daim hlau koom thiab yuav ua li cas weld zoo assured?
Corner seams los ntawm SAW nyob rau hauv WPS / PQR nrog diaphragms ua ntej; tseem ceeb thiab tag nrho -kev nkag mus welds UT/RT Qib I/II thiab kaum fillets tshuaj xyuas.
Koj puas muab engineering tsim thiab kos duab?
Yog - Tekla (BIM) nthuav dav, khw / kos duab kos duab, kos rau GB 50017, EN 1993-1-1 lossis AISC 360; diaphragm spacing thiab piv / buckling curves teem rau load.
Koj puas muab traceability thiab thib peb -kev soj ntsuam tog?
Yog - MTC, vuam/NDT (UT/RT), cov ntaub ntawv txheej thiab cov txiaj ntsig seem; SGS / BV / TÜV thib peb- tog tshuaj xyuas raws li kev thov.
