Peb cov kev cai loj -span steel trusses yog qhov kev xaiv zoo tshaj plaws rau cov haujlwm uas xav tau qhov chaw dav dav, tsis muaj kev cuam tshuam hauv pem teb. Los ntawm kev siv siab - tensile structural steel thiab optimized geometric configurations, peb muab trusses muaj peev xwm spanning tshaj 60 meters tsis muaj sab hauv. Txhua lub tshuab truss yog kev cai- engineered siv cov software siab heev kom tau raws li cov huab cua hauv cheeb tsam, daus, thiab seismic loads. Los ntawm daim duab peb sab thiab Pratt designs mus rau complex qhov chaw trusses, peb xa Hoobkas -prefabricated modules uas ua kom ceev ceev ntawm - qhov chaw sib dhos thiab uncompromising structural kev ncaj ncees.
Engineering Performance & Design Notes
Nqe lus no piav qhia seb qhov loj -span truss nqa lub load thiab seb nws raug kuaj li cas, yog li koj tuaj yeem hais qhia nws nrog kev ntseeg siab.
Clear -span kev lag luam- siab zog-rau- qhov hnyav piv cia cov kab dav dav -dawb bays yuav raug framed nrog lub teeb trusses uas qis tiv thaiv kab teeb.
Kev thauj khoom hauv cheeb tsam- tsim raws qhov chaw cua, daus thiab seismic zones; tsis yog ib qho -size profile.
Stability & bracing- sab saum toj chords txwv los ntawm purlins thiab lub ru tsev bracing dav hlau tiv thaiv lateral -torsional buckling.
Deflection tswj- nruab nrab- ncua li ntawm L / 200 (L / 240 hauv qab nthab / cladding); camber ntxiv rau ntev spans.
Field splice tsim- prefab modules koom nrog siab - lub zog bolts; NDT clears zais welds.

Koj puas tuaj yeem tsim kom muaj cua daj cua dub hauv cheeb tsam?
Yog - txhua lub truss yog engineered rau AISC 360 / EN 1993-1-1 / GB 50017 thiab nthuav dav rau qhov chaw cua, daus thiab seismic loads.
Nws thauj thiab sib dhos li cas?
Trusses nkoj raws li lub thawv - tus phooj ywg tus lej modules thiab teb -bolt sai sai rau erection drawings.
Koj puas muab kev tsim, lossis tsim rau kev kos duab?
Ob leeg - ib qho - nres tsim- thiab - tsim los ntawm Tekla 3D, los yog fabrication nruj me ntsis rau koj cov duab kos.
