● Cov qauv tsim
Qhia qhov tsim nyog thiab yooj yim txoj kev los hloov lub longitudinal kab rov tav quab yuam thiab shorten txoj kev hloov lub quab yuam kom ntau li ntau tau; Nws muaj peev xwm muab lateral fulcrums rau tag nrho kev ruaj ntseg ntawm cov qauv thiab cov khoom, thiab txo qhov ntev ntawm cov khoom tawm ntawm lub dav hlau; Ua tau raws li qhov tsim nyog lub zog thiab kev nruj nruj kom ntseeg tau qhov kev ntseeg tau ntawm kev sib txuas; Nws yog qhov yooj yim rau kev teeb tsa thiab ua kom muaj kev ruaj ntseg ntawm steel qauv cog thaum lub sij hawm installation.
● Kev them nyiaj yug daim ntawv thiab layout hauv paus ntsiab lus ntawm txhua kab
Cov kem bracing ntawm steel qauv Rhiav feem ntau muaj peb qhov chaw: sab qis bracing thiab qis kem khi bar teem los ntawm crane nqaj lossis crane truss mus rau sab ko taw; Lub sab sauv txhawb nqa nruab nrab ntawm lub crane nqaj lossis crane truss thiab qis chord ntawm lub ru tsev truss; Vertical kev txhawb nqa thiab sab sauv thiab qis khi tuav nyob rau hauv qhov siab ntau ntawm lub ru tsev truss xaus. Daim ntawv ntawm sab sauv txhawb nqa feem ntau yog hla, herringbone, splay, thiab lwm yam; Daim ntawv ntawm kev txhawb nqa sab qis feem ntau yog tus ntoo khaub lig zoo li tus, herringbone, thiab lwm yam. Qhov chaw txhawb nqa ntawm sab qis yuav tsum tau teem rau hauv nruab nrab ntawm qhov ntsuas kub kom deb li deb tau. Lub sab sauv txhawb nqa yuav tsum tau teem rau ntawm ob qho kawg ntawm qhov kub thiab txias ntxiv rau ntawm kab sib nrug nrog rau sab qis.
● Seem daim ntawv thiab suav kev txhawb nqa ntawm txhua kab
1. Seem daim ntawv xaiv. Kem bracing ntawm steel qauv Rhiav yog muab faib ua ib daim bracing thiab ob daim bracing. Qhov zoo dua qhov seem raug xaiv, qhov siab dua qhov ruaj khov ntawm qhov kev txhawb nqa bar. Thaum siv ib qho kev txhawb nqa, feem ntau siv ib lub kaum sab xis tsis sib xws, thiab sab luv yog txuas nrog kem, los yog ob lub kaum sab xis steels yog siv los tsim T-shaped seem. Thaum siv ob npaug ntawm kev txhawb nqa, sab ntev ntawm ob lub kaum sab xis hlau tsis sib xws lossis ntu uas muaj ob lub kaum sab xis steel feem ntau yog siv los txuas nrog kem. Thaum lub zog sab hauv ntawm kev txhawb nqa loj, cov seem uas muaj I-steel lossis U-steel tuaj yeem siv tau, thiab ob qho tib si ntawm kev txhawb nqa yuav tsum tau txuas nrog cov hlua khi.
2. Internal quab yuam xam ntawm bracing ntawm txhua kab. Lub longitudinal kab rov tav quab yuam ua rau bracing ntawm txhua kab muaj xws li longitudinal cua load, longitudinal kab rov tav load ntawm crane thiab lwm yam kab rov tav loads. Longitudinal cua load: concentrated cua load W kis tau los ntawm gable ntawm ob sab ntawm lub tsev; Txheem tus nqi ntawm longitudinal kab rov tav load ntawm crane Td; Lwm cov kab rov tav loads H ua rau ntawm txoj kab ntev ntawm lub tsev. Thaum ob lossis ntau qhov kev txhawb nqa inter kem tau teeb tsa, tag nrho cov kab rov tav kab rov tav loads ntawm kab kem sib koom los ntawm txhua qhov kev txhawb nqa nruab nrab ntawm kab ke.
3. Slenderness ratio xyuas kev suav ntawm kev txhawb nqa bar. Qhov luaj li cas ntawm cov neeg txhawb nqa nruab nrab ntawm cov kab ke ntawm cov qauv steel rhiav tuaj yeem txiav txim siab los ntawm kev suav, thiab qhov sib piv slenderness yuav tsum raug kuaj xyuas thiab suav. Qhov sib piv slenderness yuav tsum tsis pub tshaj tus nqi tso cai teev nyob rau hauv specification.
