Plaub Qhov Tseem Ceeb Steel Structure Systems
Cov qauv hlau raug cais los ntawm cov txheej txheem tsim thiab thauj khoom- tawm tsam tus cwj pwm mus rau plaub yam tseem ceeb: portal thav duab, thav duab qauv, truss qauv thiab qhov chaw thav duab. Txhua qhov system muaj cov yam ntxwv sib txawv hauv kev muaj peev xwm, kev coj tus cwj pwm, tus nqi thiab kev tsim kho ceev. Phau ntawv qhia no piav qhia txhua hom thiab muab qhov project-cov txheej txheem xaiv xaiv rau cov neeg ua haujlwm engineering, cov tuam txhab tsim khoom thiab cov tswv haujlwm.
Portal ncej qauv
Lub portal thav duab yog ib qho qis-nce system ntawm kab ntsug thiab kab ru tsev rafters txuas nrog nruj, lub sijhawm- tiv thaiv cov pob qij txha, uas tshem tawm cov kab hauv sab hauv thiab tsim kom pom dav dav - qhov chaw dav. Cov khoom tseem ceeb yog kab, rafters, eaves brackets, purlins thiab girts, thiab longitudinal bracing. Load paths yog yooj yim thiab ncaj qha, thiab lub system feem ntau configured raws li ib tug -span los yog multi-span nrog pinned los yog tsau kem bases. Nws haum rau ib qho - tsev warehouses, factories, garages thiab exhibition halls, thiab yog yus muaj los ntawm kev tsim kho ceev thiab nqi tsawg.
Ncej (moment frame) qauv
Cov txheej txheem steel yog lub cev pob txha ntawm cov kab ntsug thiab kab rov tav I- cov kab teeb txuas txuas los ntawm cov pob qij txha los yog pinned, ua kom muaj kev thauj khoom spatial- tiv thaiv kab ke rau ntsug loads (tus kheej- hnyav, pem teb loads) thiab lateral loads (cua, seismic). Nws muaj cov txheej txheem hloov tau yooj yim, siv qhov chaw siab thiab muaj zog tag nrho kev ncaj ncees, thiab yog cov txheej txheem tseem ceeb rau ntau-storey thiab siab- nce kev lag luam vaj tse, chaw ua haujlwm, khw malls, tsev so thiab cov khoom siv txhawb nqa.
Truss qauv
Lub truss qauv yog ib lub moj khaum ntawm cov tswv cuab ncaj uas teem rau hauv daim duab peb sab, tiv thaiv loads los ntawm axial nro thiab compression. Nws nta lub teeb rau tus kheej- hnyav, muaj peev xwm ncua ntev thiab siab tawv, ua rau nws zoo tagnrho rau ntev -span ru tsev ntawm kev ua si nawv, chaw ua yeeb yam thiab tshav dav hlau terminals, nrog rau cov choj thiab crane booms.
Qhov chaw thav duab
Ib qho chaw thav duab yog ib qho peb - qhov ntev rigid truss system ntawm interconnected linear cov tswv cuab thiab cov node connectors, xws li welded hollow spherical pob qij txha, bolted spherical pob qij txha thiab steel phaj pob qij txha. Nws faib cov loads nyob rau hauv tag nrho cov kev taw qhia nyob rau hauv lub geometric matrix, ua kom tiav kab loj heev - dawb spans nrog muaj zog seismic thiab cua tsis kam. Nws yog siv rau theatres, natatoriums, domes, tus xov tooj - chaw nres tsheb canopies thiab tos concourses.
Yuav Ua Li Cas Xaiv Txoj Cai Steel Structure System
Los ntawm lub tsev qhov siab thiab tus naj npawb ntawm storeys
Rau ib qho -cov tsev lag luam hauv tsev, warehouses thiab cov chaw ua haujlwm yooj yim, cov qauv ntawm lub portal muab cov qauv yooj yim thiab cov nqi qis dua. Rau ntau-cov tsev tsev, nruj- steel ncej sib koom ua ke muab kev ruaj ntseg tag nrho thiab ua tau raws li qhov xav tau ntsug thiab seismic ntawm nruab nrab- nce kev tsim kho.
Raws li lub ru tsev span thiab spatial xav tau
Portal thav duab yog kev lag luam rau cov pa nruab nrab nruab nrab hauv ib qho -cov tsev. Cov qauv Truss ua haujlwm rau cov tsev loj loj uas xav tau kem- qhov chaw dawb ntawm qhov ntau dua, thiab qhov chaw thav duab raug xaiv rau ultra- cov spans loj, irregular curved geometries thiab peb -dimensional load distribution.
Los ntawm hom kev thauj khoom thiab kev ua haujlwm
Ib txwm zoo li qub- lub tsev thauj khoom tau txais txiaj ntsig zoo los ntawm cov khoom siv portal lossis steel ncej. Hnyav-cov vaj tsev ua haujlwm zeb nrog cov nyiaj siv ua haujlwm cranes xav tau cov thav duab ntxiv nrog cov tswv cuab txhim kho thiab sib koom ua ke. Rau siab seismicity, siab cua siab los yog qis-kub tej yam kev mob, qhov chaw thav duab muaj ntau yam zoo xws load faib thiab ntau dua tag nrho cov kev nyab xeeb.
Los ntawm qhov project pob nyiaj siv thiab lub sijhawm
Portal thav duab muaj cov tswv cuab tsawg dua thiab qib siab ntawm prefabrication, muab lub sijhawm siv luv tshaj plaws thiab cov nqi pheej yig tshaj. Steel trusses thiab multi-storey thav duab sib npaug zoo thiab ua haujlwm tau zoo rau feem ntau cov pej xeem thiab kev lag luam. Qhov chaw thav duab xav tau kev cai tsim thiab kev teeb tsa tshwj xeeb thiab feem ntau yog tshwj tseg rau cov tsev tsim khoom.
Los ntawm kev kho thiab nthuav dav yav tom ntej
Ntau-storey steel thav duab nrog cov layouts hloov tau yooj yim hloov tau zoo tshaj plaws rau yav tom ntej ntsug ntxiv thiab kev hloov kho spatial. Truss thiab qhov chaw thav duab, nrog rau lawv cov kev ruaj ntseg tag nrho, haum rau pej xeem cov tsev uas xav tau kev pab lub neej ntev thiab kev saib xyuas tsawg.

Cov lus nug nquag
Vim li cas cov duab peb sab siv hauv steel trusses?Daim duab peb sab tsis hloov cov duab nyob rau hauv load: txhua tus tswv cuab nqa axial nro los yog compression nkaus xwb, uas ua rau lub truss inherently ruaj khov thiab zoo heev nyob rau hauv cov khoom siv.
Dab tsi yog qhov txawv ntawm ib lub thav duab thiab qhov chaw ncej?thav duab resists loads feem ntau nyob rau hauv dav hlau, los ntawm kab thiab kab teeb nyob rau hauv ob -dav layouts. Ib qhov chaw thav duab yog peb - qhov sib txuas sib txuas sib txuas uas faib cov khoom thauj hauv txhua qhov kev qhia, uas haum rau lub ru tsev qhib loj heev thiab cov geometry nyuaj.
Puas yog steel qauv prefabricated?Yog lawm. Cov khoom feem ntau yog fabricated thiab coated nyob rau hauv lub Hoobkas, ces thauj thiab bolted ua ke ntawm qhov chaw, uas shortens lub sij hawm tsim kho thiab txhim kho kev tswj kom zoo.
Vim li cas cov thav duab siv rau cov tsev siab -nce?Cov ncej steel muaj lub zog siab - rau- qhov hnyav piv, yog li cov qauv txhawb nqa nws tus kheej qhov hnyav zoo thaum tiv thaiv cua thiab seismic zog; Cov kev sib txuas tsis sib haum faib cov loads sab nraud los ntawm tag nrho cov system.
Yuav ua li cas truss qauv txuag cov khoom siv?Vim tias cov tswv cuab ua haujlwm hauv kev nruj nruj lossis compression, tag nrho seem yog siv tau zoo, txo tag nrho cov hlau tonnage uas yuav tsum tau los txhawb nqa loj qhib spans piv nrog cov khoom -web lwm txoj.
