Steel structural framing systems

Taw qhia

Cov qauv hlau yog tsim los ntawm lub cev pob txha uas muaj cov kab ntsug, kab rov tav thiab lwm yam ua los ntawm cov ntaub ntawv steel, riveted, welded los yog bolted ua ke, feem ntau nyob rau hauv daim phiaj rectilinear.Cov qauv hlau feem ntau yog siv rau nruab nrab thiab siab-nce, kev lag luam, warehouse thiab vaj tsev nyob.

Qhov zoo ntawm cov qauv steel muaj xws li:

Resilience rau av qeeg thiab cua loading.Ease of construction and deconstruction.Lub sij hawm tsim kho luv.Resistance hluav taws kub thaum kho.Yuav siv tau ua ke nrog lwm hom kev tsim kho.Easy mus koom.High precision.Offsite fabrication.Highratios ntawm lub zog rau qhov hnyav thiab lub zog rau ntim.Pom ntev meej spans.Nqe kab.Can ua kom raug

Steel structural systems

Lub ntsiab steel vaj tse ntsiab xws li phab ntsa, pem teb, ru tsev thiab bracing cov tswv cuab tuaj yeem npaj kom muaj qee yam kev ua haujlwm uas pab txhawb kev ruaj ntseg ntawm lub tsev nyob ntawm seb hom lossis siv lub tsev, qhov xwm txheej thiab kev siv ntawm kev siv. loads thiab tsim lub neej xav tau

Phab ntsa bearing framing

Phab ntsa bearing framing muaj erection ntawm masonry phab ntsa nyob rau hauv perimeter thiab sab hauv ntawm lub tsev thiab cov structural steel cov tswv cuab yog ces anched rau ntawm masonry phab ntsa siv bearing thiab kawg steel daim hlau thiab thauj tog rau nkoj bolts.Kev tsim thiab kev tsim kho ntawm phab ntsa bearing framing nyob ntawm qhov kev siv zog thiab qhov kev ncua deb ntawm kev txhawb nqa txuas ntxiv.

Thaum cov kab hluav taws xob qis qis pab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhavNtawm qhov tod tes, sib sib zog nqus beam thav duab pab kom ncua ntev.

Skeleton framing

Nov yog kab-beam structural moj khaum system, nyob rau hauv uas tag nrho cov lateral thiab lub ntiajteb txawj nqus loads raug xa mus rau lub steel moj khaum thiab pauv mus rau lub hauv paus.Phab ntsa yog ua los ntawm cov ntaub thaiv phab ntsa uas tsis muaj kev thauj khoom.Skeleton framing feem ntau muaj cov kab hluav taws xob, cov kab hluav taws xob loj lossis cov kab nruab nrab, cov kab nruab nrab lossis theem nrab, cov phab ntsa thiab cov kab sab hauv thiab cov pob zeb ua kom muaj zog.Rau eccentric kev sib txuas ntawm kem thiab kab teeb muaj ntau yam kev koom tes xws li kev siv cov hlau brackets, gusset daim hlau thiab haunches uas pab faib cov induced stresses.Shims pab ua kab thiab kho qhov siab.Shelve angle brackets pab txhawm rau txuas lub nqaj qaum thiab kem.

Long-span framing

Qhov ntev ntev yog qhov ntev tshaj 12m.Nws pab muab qhov chaw yooj yim hauv pem teb, kem tsis pub muaj qhov chaw sab hauv, txo cov sij hawm tsim kho ntawm qhov chaw, tso cai rau kev teeb tsa ntau yam kev pabcuam thiab sib xyaw siv qhov chaw.Nws feem ntau yog siv rau cov tsev lag luam loj, auditoriums, theatres, exhibition chaw thiab lwm yam.

Cov txheej txheem hauv qab no yog siv;stub girders, hunched composite beams, composite trusses, cantilever suspensions spans, folded daim hlau, curvilinear daim phiaj, nyias plhaub domes, cable tes hauj lwm, qhov chaw trusses, portal thav ntawv thiab hais txog.

Girders

Cov no yog cov kab hlau sib sib zog nqus uas pab ua kom ntev mus ntev.Qhov ntev ntawm qhov ntev nyob ntawm qib girder steel thiab qhov sib sib zog nqus qhov sib piv.Girders tau nruab rau hauv ntau txoj kev muaj cov stub girders uas span longitudinally hla cov qauv txuas nrog lub ntsiab girders thiab hybrid girders cov no yog cov manipulated girders stiffened nqa ntau dua loads los ntawm kev ntxiv ntawm cov welded qhov chaw nyob rau hauv lub sab saum toj thiab hauv qab. flanges.

Tuav

Trusses muaj qhov zoo ntawm kev ncua ntev vim qhov tob dua lawv muaj ua rau lawv tawv tawv tiv thaiv deflections.Cov hom trusses siv rau kev tsim kho ntev xws li Pratt trusses, Warren Trusses, Fink Trusses, txiab, Hneev hlua thiab Vierendeel Trusses.Yog xav paub ntxiv mus saib: Truss.

Cov ntaub ntawv truss no tuaj yeem siv los ua cov tswv cuab tseem ceeb hauv cov txheej txheem hauv pem teb thiab lub ru tsev.

Rigid ncej

Lub degree ntawm rigidity nyob rau hauv lub beam-kem kev sib txuas yuav tsum tau ua tib zoo soj ntsuam.Nyob rau hauv nruj thav duab sib txuas yog tsim los dais ob lub sijhawm dabtsi yog khoov thiab shear quab yuam.Lawv yog tsim raws li tag nrho nruam nruam los ntawm tag nrho qhov ntev thiab qhov siab nyob rau hauv qhov tsis muaj hinges los yog pins nyob rau hauv lub crowns thiab nyob rau hauv nruab nrab-span.

Lub hauv paus loj nruj pab nqa thiab faib lub sijhawm thiab txiav rau hauv av.Rau cov laj thawj kev lag luam hauv av yuav tsum tau kuaj xyuas vim tias nws tuaj yeem ua rau cov nqi siab dua hauv cov av tsis zoo.

Arches

Arches tuaj yeem ua tau raws li cov khoom arches lossis qhib web arches, peb lub hinged, ob lub hinged lossis ruaj arches.Cov no nyob ntawm seb cov khoom siv li cas yuav tsum tau siv, lub zog muaj peev xwm, thauj tog rau nkoj, siv lub tsev, hom hauv paus thiab qhov chaw thau khoom.

Peb lub hinged koov tuaj yeem pab kom ncua ntev txawm tias muaj cov xwm txheej tsis zoo xws li huab cua tsis zoo, cov khoom hnyav hnyav thiab lwm yam.Ob lub pinned arches tsis tshua muaj zog piv rau peb lub hinged arch lug.Tsau arches yog siv rau hauv cov tsev nrog cov khoom sib zog thiab cov av zoo.
