Q: Yam khoom ntawm Galvanized lub kaum sab xis hlau ncaj qha cuam tshuam cov qauv kev ruaj khov?
A: Sab ntev: Cov ntu loj dua, muaj ntau dua ntawm ntu (muaj peev xwm tiv thaiv kev puas ntsoog), uas yog tsim rau cov kabmob khoov lossis loj heev.
Thickness (t): nyob rau hauv tib sab ntev, qhov loj dua lub thickness, loj dua ntawm gyration (a) thiab lub zog sib xyaw ua ke.
Slenderness piv (λ): sledness piv rau ntsuas qhov ntsuas tau ruaj khov rau kev ntsuas qhov muaj peev xwm (}
Cov khoom siv thiab Galvanized Txheej: cov khoom siv (xws li Q235, Q355) txiav txim lub zog ntawm cov hlau; lub thickness ntawm cov galvanized txheej (kub-dip galvaning ntau dua los yog sib npaug ntawm cov khoom siv tshuab, tab sis cov nyhuv ntawm cov neeg kho tshuab tuaj yeem suav nrog cov qauv tsim).
Q: Dab tsi yog cov kev cuam tshuam tshwj xeeb ntawm cov ntsiab lus tshwj xeeb ntawm cov qauv kev ruaj ntseg?
A: Axial Tension:
Cov lus tseem ceeb: hla cheeb tsam (a) .
Cov nyhuv: Cov kab mob hla tsis txaus sab hauv yuav ua rau cov hlau kom tawm los yog tawg}
Axial compression:
Cov kev tsis tseem ceeb: hla ntu (a), vojvoog ntawm gyration (i), slenderness piv (λ) .
Cawv: Cov kev sib txig loj dhau yog nquag mus rau qhov tsis txaus ntseeg (xws li khoov tsis ua tiav ntawm cov txheej txheem hlau).
Cov neeg muaj khoov (xws li purlins, txhawb nqa)
Cov Ntsiab Lus: Tshooj Modulus (WX, WY), lub caij ntawm inertia (ix, iy) .
Cuam tshuam: Seem tsis txaus yuav ua rau muaj kev sib tw tsis sib haum xeeb (xws li lub zog ntawm inertia (xws li lub zog ntawm cov qauv (xws li ru tsev tole. .
Bidirectional Force thiab cov kev nyuaj siab nyuaj siab
Piv txwv, lub kaum ntse ntse nyob rau hauv truss cov nodes thiab kev txhawb nqa cov kab ke yuav raug muab los ua ke cov nro, khoov thiab shear tib lub sijhawm .
Tus yuam sij: Nws yog ib qho tsim nyog los xyuas cov kev nyuaj siab ntawm ntu (xws li siv lub zog thib plaub - kom tsis txhob muaj ntau qhov tsis txaus siab vim tias me me.
Cov ntsiab lus tsim: Cov ntu ua ntej loj dua hluav taws xob (xws li cov sib npaug ntawm cov hlau uas muaj vaj huam sib luag) txhawm rau txhim kho bidirectional ruaj khov {}}
Q: Qhov kev pheej hmoo ntawm kev xaiv tshwj xeeb?
A: Cov khoom tsis txaus: Cheebtsam tsis txaus thiab weld tawg .
Tsis muaj zog ruaj khov: ntau dhau ntawm purlin sagging tshaj li kev txwv ntawm lub ru tsev nce lub nra) .
Zuag qhia tag nrho cov tsis tau: Cheebtsam buckling (xws li kev khoov ntawm cov txheej txheem hlau) lossis tag nrho eturning ntawm cov qauv .
Kev tawm tsam tsis ncaj ncees ntawm kev tiv thaiv kev ruaj khov: yog tias cov txheej txheem ntawm lub galvanized {2} Ua rau muaj peev xwm siv tau rau kev coj tus neeg muaj peev xwm ntev los yog ua kom tsawg dua li ntawm kev siv lub peev xwm lossis nrawm nrawm.
Q: Cov ntsiab cai tseem ceeb rau kev xaiv tshwj xeeb li cas?
A: Raws li kev thauj cov kev xam: Qhia meej lub nra (Axial Dag, thiab txiav txim siab}), thiab txiav txim siab siv tshuab hluav taws xob, shear zog) los ntawm kev sib cais ntawm cov kab ke sib cais.
Ua ntej kev ruaj khov pov thawj: compression tus tswv cuab: Txheeb xyuas cov kab ke uas muaj peev xwm loj dua lossis sib npaug ntawm cov qauv steel) .
Xav txog cov qauv kev sib txuas: Node kev twb kev txuas: Qhov kev sib txuas ntawm lub hnub qub qis dua lossis sib npaug ntawm 2} Bolt Bolt diam -} bolt interting .
Anti-corrosion matching: Hot-dip galvanized angle steel (plating>=85μm) is used in high-corrosion environments to extend the life of the structure and indirectly ensure stability.
Sib npaug ntawm kev lag luam thiab kev siv zog: zam "oversized specifications" ua rau cov khoom pov tseg "ua rau cov khoom siv tsawg heev" ua rau muaj kev phom sij kev nyab xeeb "ua rau muaj kev phom sij kev nyab xeeb"
Q: Dab tsi yog qhov tseem ceeb ntawm cov tub ntxhais kawm ntawm kev xaiv tshwj xeeb?
A: Qib kev kho tshuab: kom meej tias cov khoom siv tsis raug kev txom nyem lossis tsis muaj zog nyob rau hauv thaj chaw xws li inertia, thiab slenderness piv;
Anti-Corrosion Theem Corrosion: Xaiv cov kub-dip Galrosive ib puag ncig kom tsis txhob muaj xeb uas tsis muaj zog ntawm cov ntoo khaub ncaws thiab ncaj qha cuam tshuam kev ruaj khov;
Economic Theem: Xaiv cov lus qhia tshwj xeeb, zam dhau kev tsim nyog lossis kev pheej hmoo tsim, thiab coj mus rau hauv tus account kev nyab xeeb thiab raug nqi .
