Galvanized Commercial Steel Structural Pipe Truss Roof Rau Khw Muag Khoom

Cov yeeb nkab truss hais txog cov qauv lattice tsim los ntawm kev sib txuas cov pas nrig ntawm qhov kawg.Lub truss ua rau cov khoom siv truss kev lag luam, thiab cov qauv yog lub teeb hauv qhov hnyav, thiab nws yog ib qho yooj yim los tsim ntau yam duab los hloov mus rau ntau lub hom phiaj, xws li kev txhawb nqa trusses, arches, thav duab, thiab yees.

Piv nrog rau cov qauv kab sib chaws, cov qauv tubular truss txuag lub qis chord longitudinal cov tswv cuab thiab cov pob qij txha ntawm cov kab sib chaws, uas tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm ntau cov ntaub ntawv hauv tsev, tshwj xeeb tshaj yog kev tsim kho ntawm puag ncig arches thiab arbitrary curved duab yog qhov zoo tshaj qhov kab sib chaws.Nws ruaj khov nyob rau hauv tag nrho cov lus qhia yog tib yam, txuag cov khoom siv.Lub steel yeeb nkab truss qauv yog tsim nyob rau hauv lub hauv paus ntawm daim phiaj qauv.Piv nrog rau cov qauv kab sib chaws, nws muaj nws qhov tshwj xeeb zoo thiab kev ua tau zoo, thiab tus nqi ntawm cov qauv hlau kuj tseem pheej yig dua.

Kev ua tau zoo:

1. Lub zog:

Lub zog Performance index ntawm steel yog tsim los ntawm elastic txwv σe, yield limit σy, thiab tensile limit σu.Cov qauv tsim yog ua raws li lub zog tawm los ntawm cov hlau.High yield zog tuaj yeem txo qhov hnyav ntawm cov qauv, txuag steel, thiab txo tus nqi.Lub zog tensile σu yog qhov siab tshaj plaws uas cov hlau tuaj yeem tiv taus ua ntej tsis ua haujlwm.Lub sijhawm no, cov qauv poob nws qhov kev ua tau zoo vim yog cov yas loj deformation, tab sis cov qauv tsis deformed thiab tsis tawg, uas ua tau raws li qhov yuav tsum tau ua ntawm cov qauv los tiv thaiv av qeeg tsawg.'Σu / σy tus nqi tuaj yeem suav tias yog qhov ntsuas ntawm steel lub zog cia.

2. Plasticity:

Lub plasticity ntawm steel feem ntau yog hais txog cov cuab yeej ntawm muaj cov yas deformation tseem ceeb yam tsis tau tawg tom qab qhov kev ntxhov siab tshaj qhov taw tes tawm.Lub ntsiab indexes los ntsuas cov yas deformation muaj peev xwm ntawm steel yog elongation δ thiab seem shrinkage ψ.

3. Txias bending kev ua tau zoo:

Qhov txias khoov kev ua tau zoo ntawm cov hlau yog ib qho kev ntsuas ntawm qhov tsis kam ntawm cov hlau kom tawg thaum cov yas deformation tshwm sim ntawm chav tsev kub.Qhov txias dabtsi yog khoov kev ua tau zoo ntawm cov hlau yog siv qhov kev sim txias bending los kuaj qhov khoov deformation kev ua tau zoo ntawm cov hlau raws li qhov kev qhia khoov.

4. cuam tshuam toughness:

Qhov cuam tshuam toughness ntawm steel yog hais txog lub peev xwm ntawm cov hlau kom nqus tau txhua yam kinetic zog thaum lub sij hawm tawg nyob rau hauv qhov cuam tshuam load.Nws yog ib qho cuab yeej cuab tam uas ntsuas qhov tsis kam ntawm cov hlau los cuam tshuam cov load.Nws tuaj yeem ua rau pob txha tawg vim qhov kub thiab txias thiab kev ntxhov siab.Qhov cuam tshuam toughness Performance index ntawm steel feem ntau tau los ntawm qhov kev ntsuam xyuas ntawm cov qauv xeem.

5. Welding kev ua tau zoo:

Vuam kev ua tau zoo ntawm cov hlau hais txog vuam cov pob qij txha nrog kev ua tau zoo nyob rau hauv qee yam txheej txheem vuam.Vuam kev ua tau zoo tuaj yeem muab faib ua vuam kev ua tau zoo thiab kev ua haujlwm vuam hauv cov txheej txheem vuam.Vuam kev ua tau zoo nyob rau hauv cov txheej txheem welding yog hais txog qhov tsis zoo ntawm cov vuam seam thiab cov hlau nyob ze ntawm lub vuam seam kom tsis muaj thermal tawg lossis txias shrinkage tawg thaum lub sij hawm vuam.Kev ua haujlwm vuam zoo txhais tau hais tias nyob rau hauv qee qhov txheej txheem vuam, cov hlau vuam thiab cov hlau nyob ze yuav tsis tawg.Lub vuam kev ua tau zoo nyob rau hauv cov nqe lus ntawm serviceability yog hais txog qhov cuam tshuam toughness thiab ductility ntawm tshav kub cuam tshuam cheeb tsam ntawm weld seam.Tuam Tshoj txais cov kev ntsuas kev ua tau zoo ntawm kev siv vuam hauv cov txheej txheem vuam, thiab tseem siv cov txheej txheem vuam kev ua tau zoo hauv qhov kev siv tau.

6. Durability:

Muaj ntau ntau yam uas cuam tshuam rau cov kav hlau.Thawj yog qhov tsis zoo corrosion tsis kam ntawm cov hlau, thiab kev tiv thaiv kev tiv thaiv yuav tsum tau coj los tiv thaiv steel corrosion thiab xeb.Kev tiv thaiv kev tiv thaiv muaj xws li: kev saib xyuas cov xim hlau tsis tu ncua, kev siv cov hlau galvanized, thiab kev siv cov kev tiv thaiv tshwj xeeb thaum muaj cov khoom muaj zog corrosive xws li acids, alkalis, thiab ntsev.Lub zinc ingot yog tsau rau ntawm lub tsho, thiab cov dej hiav txwv electrolyte yuav cia li corrode zinc ingot ua ntej, thiaj li ua tiav txoj haujlwm ntawm kev tiv thaiv lub tsho hlau.Thib ob, vim qhov kub thiab txias thiab lub sijhawm ntev, qhov kev puas tsuaj lub zog ntawm cov hlau yog qis dua li ntawm lub sij hawm luv luv.Yog li ntawd, lub sij hawm ntev ntawm high-temperature steel yuav tsum tau kuaj rau lub sij hawm ntev zog.Cov hlau yuav cia li ua tawv thiab tawv thaum lub sijhawm, uas yog qhov tshwm sim ntawm "kev laus".Qhov cuam tshuam toughness ntawm steel nyob rau hauv qis kub load yuav tsum tau kuaj.

Piv nrog rau cov tsoos steel trusses nrog qhib cross-sections (H-shaped steel thiab I-shaped steel), cov khoom ntawm cov yeeb nkab truss qauv yog ntau tusyees faib nyob ib ncig ntawm lub nruab nrab axis, thiaj li hais tias tus ntoo khaub lig-section muaj zoo compressive thiab flexural- torsional bearing muaj peev xwm thiab ntau dua rigidity.Tsis muaj gusset phaj, cov qauv yog yooj yim.Qhov tseem ceeb tshaj plaws yog cov qauv tubular truss zoo nkauj zoo nkauj, uas yooj yim rau kev ua qauv thiab muaj qee yam zoo nkauj.Tag nrho cov kev ua tau zoo ntawm cov yeeb nkab truss qauv yog zoo, lub torsional rigidity yog loj, thiab cov tsos zoo nkauj.Nws yog ib qho yooj yim los tsim, nruab, tig, thiab nqa;cov yeeb nkab steel ru tsev truss ua los ntawm txias-tsim nyias-walled steel muaj lub teeb qauv, zoo rigidity, steel txuag, thiab muaj peev xwm muab tag nrho cov kev ua si rau qhov zoo ntawm cov khoom siv zog, thiab lwm yam., yog ntau yig, tshwj xeeb tshaj yog nyob rau hauv lub strut thiab kev txhawb zog system. tswj los ntawm qhov sib piv slenderness.Cov vaj tsev nrog cov qauv no yog cov vaj tsev hauv pej xeem.Cov qauv muaj cov yam ntxwv zoo nkauj zoo nkauj (nws tuaj yeem ua rau hauv cov duab tiaj tus, puag ncig arch shape, arbitrary curve shape), yooj yim tsim thiab installation, zoo structural stability, siab ru tsev rigidity, thiab zoo economic nyhuv.

Peb lub tuam txhab cov khoom lag luam steel tuaj yeem ua tau raws li ntau yam qauv thoob ntiaj teb xws li Australian tus qauv, New Zealand tus qauv, tus qauv Askiv thiab Asmeskas tus qauv.Zoo siab txais tos koj qhov kev nug.
