Cov txheej txheem steel khi beam yog lub Hoobkas -prefabricated kab rov tav txuas cov tswv cuab uas txuas cov kab hlau tseem ceeb thiab cov kab ru tsev ntawm ib lub thav duab, sib npaug axial quab yuam thiab txwv kev deformation sab nraud kom txhawb nqa tag nrho cov rigidity ntawm lub ru tsev framing system. Raws li lub hauv paus strut nyob rau hauv lub bracing system nws kis longitudinal cua loads ntawm lub gable kawg thiab crane braking rog los ntawm kem bracing rau lub hauv paus, koom ib tug neeg tsim thav duab rau hauv ib tug ruaj khov spatial skeleton thaum lub sij hawm erection, thiab muab lateral bracing ntsiab lus uas shorten lub zoo ntev ntawm compression tswv cuab.
Peb tsim ob qho tib si nruj kev sib raug zoo - los ntawm CHS, RHS / SHS los yog HFW H- ntu, muaj peev xwm nqa nro thiab compression - thiab hloov tau yooj yim los ntawm ib lub ces kaum los yog puag ncig tuav rau ntshiab- nro bracing, hauv Q235/Q355, S235/S355.

Lub luag haujlwm ntawm Tie Beam
Hloov ntawm Longitudinal Horizontal Forces
Transmits cua loads ua yeeb yam ntawm lub gable kawg thiab longitudinal crane braking rog los ntawm khi kab teeb rau hauv kem bracing system, thiab thaum kawg mus rau lub hauv paus.
Xyuas kom tag nrho cov qauv Spatial Stiffness
Thaum lub sij hawm erection, khi beams ua hauj lwm ua ke nrog lub bracing system los tsim ib tug neeg erected rigid ncej bents rau hauv ib tug ruaj khov spatial skeleton.
Kev txiav txim siab ntev ntawm cov tswv cuab
Muab cov ntsiab lus brace rau sab laug rau cov kab ncej (tawm- ntawm- dav hlau) thiab cov kab hluav taws xob ru tsev (tawm- ntawm- dav hlau), yog li txo qhov ntev ntawm cov tswv cuab compression thiab tiv thaiv lateral buckling instability.
Tiv thaiv Lateral Displacement ntawm Purlins / Phab Ntsa Girts
Restrains lub lateral deformation ntawm purlins thaum loaded nyob rau hauv compression.
Daim ntawv thov ntawm Tie Beam
Portal Frame Industrial Buildings:Muab tso rau ntawm kab saum toj, ridges, thiab crane girder bracket qhov chaw, khi kab txuas txuas cov thav ntawv nyob ib sab thiab hloov cov kab rov tav kab rov tav mus rau lub bay haum nrog kem bracing.
Space Frames thiab Truss Structures:Nyob rau hauv complex spatial lug, khi beams txuas ib tug neeg units, kom lub spatial stability ntawm lub ru tsev system.
Tied-Arch Bridges:Lub transverse khi kab nruab nrab ntawm arch ribs tsis tsuas yog muab kev ruaj ntseg tab sis kuj ncaj qha tiv thaiv kab rov tav thrust ntawm arch springing ntsiab lus.
Siab-Rise Steel Ncej:Ua haujlwm raws li kev txuas ntxiv ntawm kev sib txuas ntawm cov kab teeb, khi kab teeb ua haujlwm sib faib quab yuam ntawm tus kheej thav duab khoov, tiv thaiv tag nrho cov kev tiv thaiv sab nraud.

FAQ:
Cov kab hlua khi feem ntau nyob qhov twg?
Lawv feem ntau yog ntsia rau saum cov kab kab, ntawm cov kab nrib pleb, thiab ntawm crane girder txhawb cov nodes. Tie beams yuav tsum tau siv ua ke nrog lub ru tsev bracing - xws li ntoo khaub lig-braced round bars - thiab feem ntau muab tso rau hauv tib lub bay raws li lub ru tsev bracing los tsim ib tug ruaj khov geometric spatial system.
Qhov txawv ntawm Tie Beams thiab Roof Purlins yog dab tsi?
Load- Cov Kabmob sib txawv: Purlins feem ntau tiv thaiv lub ru tsev loads (xws li, tuag load, daus load, cua uplift, thiab lwm yam); khi beams feem ntau tiv thaiv lub longitudinal kab rov tav quab yuam ntawm cov qauv thiab nqa me me los yog tsis muaj ntsug load.
Qhov sib txawv ntawm qhov sib txawv: Purlins nyob ze ze rau qhov chaw perpendicular rau lub ru tsev nqes hav; khi kab teeb yog teem rau tib lub sijhawm mus rau qhov ntev ntawm lub tsev, txuas ncaj qha txuas lub ru tsev truss los yog txhav ncej pob qij txha.
Yuav ua li cas xam qhov Length ntawm Tie Beams?
Lub theoretical ntev ntawm txoj hlua khi sib npaug sib npaug ntawm qhov deb ntawm ob lub ntsiab lus ruaj khov ntawm ob qho kawg. Lub ru tsev txoj kab nqes coefficient feem ntau yuav tsum tau coj mus rau hauv tus account thaum xam. Hauv kev tsim kho vaj tse thiab BIM software (xws li Glodon, thiab lwm yam), qhov ntev tuaj yeem muab tau los ntawm kev muab cov kab rov tav projection ntev los ntawm txoj kab nqes coefficient, lossis los ntawm kev ntsuas qhov ntev ncaj qha siv lub ntsuas ntsuas hauv 3D qauv.
Kev sib txuas rau lub ntsiab ncej ua li cas?
Welded kawg daim hlau ntawm ob qho kawg, bolted rau txhua kab / rafters / trusses nrog siab - lub zog bolts; Cov ncauj lus kom ntxaws rau EN 1993-1-8; fillet welds MT / PT, tag nrho cov cwj mem welds UT kuaj.
Koj muab ntawv pov thawj, traceability thiab thib peb - tog twg los soj ntsuam?
ISO 9001, EN 1090-2 (EXC2/EXC3), AWS D1.1/CWB certified welding, MTC and coating records; SGS / BV / TÜV thib peb-tog tshuaj xyuas thaum thov.
