Sag rods yog cov tswv cuab nruj uas txhawb nqa lub ru tsev purlins thiab phab ntsa girts nyob rau sab nraud - ntawm - dav hlau sab, ua kom lawv zoo sib xws kom cov hlau cladding kho squarely thiab cov ncej nyob ruaj khov nyob rau hauv cua thiab nqus. Peb cov kab pheeb ces kaum ua hauj lwm ua ke nrog cov struts los tsim ib daim duab peb sab bracing system uas txwv kev khoov sab nraud thiab torsion ntawm Z thiab C seem. Raws li ib tug thib ob-steel tsum peb txhawb koj mus txog rau thaum xaus -cov lus qhia pub dawb sizing, kev cai ntev, nyob rau hauv -lub tsev threading thiab galvanizing, thib peb- tog kuaj thiab xa tawm xa tawm - yog li dab tsi tuaj txog raws li koj daim duab thiab koj lub sijhawm.
Dab tsi yog Diagonal Sag Qws?
Nws ua haujlwm li cas
Hauv ib lub tsev hlau, Z lossis C purlins tsau ntawm ib qho kawg tuaj yeem tawm sab saum toj flange tsis txhawb nqa. Lateral loads - cua suction, seismic action, notional rog - ces thawb ntu mus rau sab nraud -torsional buckling. Ib tug pas nrig hla lub purlin web ze rau saum flange thiab yog xauv nrog txiv ntseej thiab ntxhua khaub ncaws;nws rub cov tswv cuab rov qab mus rau kab, nres sagging nyob rau hauv tuag thiab nyob load, thiab hloov lateral loads mus rau lub ncej thiab lub hauv paus.

FAQ:
Yuav ua li cas lub ru tsev suab yog tuav nrog nruam sag rods tshaj lub apex?
Tshaj li 10 degree, kho cov rods tsis tu ncua hla txoj kab, khiav ntawm lub qhov hauv qab mus rau lub qhov saum toj ntawm txhua txoj kab nqes. Hauv qab 10 degree, npaj lawv mus rau qhov kev sib tw luv tshaj plaws thiab nruj sib npaug.
Kuv yuav xaiv tus pas nrig txoj kab uas hla?
Txuas tus pas nrig rau lub purlin ncua thiab thauj khoom: kwv yees Φ12 rau lub teeb girts txog 6 m, Φ14-16 rau 6-10 m ru tsev purlins, Φ20 rau ntev spans thiab hnyav luag hauj lwm. Paub meej nrog koj tus qauv kos duab.
Kuv puas xav tau sab laug- tes xov?
Tsis yog. Standard txoj cai- tes coarse threads raug tsav mus tsev ncaj qha, txiav qhov chaw ua haujlwm. Peb kuj muab ob qho tib si - xov kawg thiab cov pas nrig tiaj nrog ib qho - xov kawg.
Dub lossis galvanized - kuv yuav xaiv qhov twg?
Dub (ua ntej- xim) haum rau sab hauv lossis cladding- zais bracing ntawm tus nqi qis; kub-dip galvanized raws li ISO 1461 haum rau qhov chaw sab nraum zoov thiab ntub dej rau ntau xyoo kev tiv thaiv.
Koj puas muab cov txiv ntseej, ntxhua khaub ncaws thiab lub caij nplooj ntoos hlav ntxhua?
Yog lawm. Cov txiv ntseej, tiaj tus thiab lub caij nplooj ntoos hlav ntxhua khaub ncaws tau muab nrog txhua tus pas nrig, qhov loj me rau lub pas nrig txoj kab uas hla, yog li koj cov pob txhim kho tiav rau qhov chaw.
Koj puas tuaj yeem txiav thiab xov rau kuv daim duab?
Tau - qhov ntev, txoj kab uas hla thiab tag nrho lossis ob qho tib si - xaus threading rau lub khw pom zoo kos duab, nrog rau daim ntawv qhia qhov ntev.
Kuv puas tuaj yeem tau txais cov qauv ua ntej ntau lawm?
Yog lawm. Cov qauv tuaj yeem ua ua ntej ntawm cov batch kom koj tuaj yeem tshawb xyuas qhov ntev, xov thiab txheej ua ntej.
