A steel truss qauvyog lub teeb yuag, nruj lub moj khaum tsim los ntawm cov qauv steel cov tswv cuab txuas nrog hauv ib qho kev sib cuam tshuam daim duab peb sab. Nws faib cov khoom hnyav dhau qhov ntev yam tsis tas yuav tsum muaj cov phab ntsa txhawb nqa sab hauv, ua rau nws tseem ceeb rau cov txuas hniav, warehouses, aircraft hangars, thiab loj -span ru tsev.
Steel Truss Structure yog dab tsi?
Lub steel truss yog ib qho kev ua haujlwm siab - ua haujlwm tau tsim los ntawm kev sib txuas ncaj nraim cov tswv cuab hauv cov duab peb sab. Qhov no geometry faib loads axially (raws li ntshiab nro los yog compression), ua kom nws nqa hnyav loads thiab ncua ntev mus tsis muaj nruab nrab kem txhawb.
Cov ntsiab lus tseem ceeb:
Tus qauv steel truss muaj peb lub ntsiab lus tseem ceeb:
Sab saum toj chord:Lub Upper ciam teb ntawm lub truss, feem ntau nyob rau hauv compression.
Hauv qab chord:Tus ciam teb qis, feem ntau nyob rau hauv nro.
Cov tswv cuab hauv Web:Sab hauv kab pheeb ces kaum thiab ntsug tuav txuas rau sab saum toj thiab hauv qab chords, ua haujlwm kom ruaj khov ntawm cov qauv thiab hloov lub zog shear.

Cov txiaj ntsig ntawm Steel Ua -Truss Structure
1. Tsawg tus kheej- hnyav thiab siab zog-rau- qhov hnyav piv
Piv nrog cov khoom-web steel beams, steel trusses concentrate cov khoom nyob rau hauv sab saum toj thiab hauv qab chords thiab cov tswv cuab hauv web, tshem tawm cov khoom siv los ntawm lub vev xaib,txo qhov zoo steel ntoo khaub lig-section los ntawm 30% mus rau 50%.
Raws li qhov sib npaug ntawm kev thauj khoom thiab ncua sijhawm, tag nrho cov qauv ntawm tus kheej - hnyav yog20% mus rau 40% sib duauas yog cov khoom siv sib xyaw ua ke -web beam, txo qis lub hauv paus bearing siab.
2.Exceptional ntev -span muaj peev xwm
Cov kab hluav taws xob steel ua tsis tshua muaj kev lag luam tshaj li 30-meter spans vim qhov poob qis hauv lub peev xwm flexural, whereas steel truss structures (xws li cov khoom siv hauv cov chaw ua si, tshav dav hlau terminals, thiab cov nroj tsuag loj) tuaj yeemyooj yim ncua 50 mus rau 150 meters yam tsis muaj kab nruab nrab.
3. Cov khoom siv tau zoo heev
Cov tswv cuab feem ntau nqa axial nro lossis compression, tso cai rau lub zog steel kom siv tag nrho. Thaum ua ke nrog siab -lub zog steel (piv txwv li, siab- qib steel qib nrog cov txiaj ntsig zoo ntawm 355 MPa txog 700 MPa), tag nrho cov hlau siv ntev ntawm -span ru tsev system tuaj yeem ua kom zoo rauua tiav 15% mus rau 30% qhov hnyav txuagpiv nrog cov qauv kev daws teeb meem.
4.Spatial siv thiab MEP kev koom ua ke
Lub truss web vaj huam sib luag muaj qhov qhib dav dav, tso cai rau HVAC cov kav dej, cov kav dej tiv thaiv hluav taws, thiab lub zog thiab qis -voltage cabling kom hla ncaj qha mus rau qhov tob tob. Qhov notxhim kho lub tsev qhov pom tseeb qhov siab siv los ntawm 10% mus rau 20%thiab txo qhov xav tau ntxiv qab nthab plenum qhov siab.
5.Shop prefabrication thiab siv tau zoo
Cov tswv cuab feem ntau yog tsim los rau cov qauv tshwj xeeb hauv lub khw thiab sib sau ua ke ntawm qhov chaw, txo qis ntawm - lub sijhawm ua haujlwm ntub dej. Piv nrog cam khwb cia-hauv- qhov chaw ua vaj tse, lub sij hawm tsim kho tag nrhotuaj yeem ua kom luv los ntawm 30% mus rau 50%.

Hu rau tam sim no kom tau txais steel truss
Dab tsi yog qhov txawv ntawm steel trusses thiab cov khoom siv sib xyaw ua ke -web beams (piv txwv li, H-section steel beams)?
Load-carrying mechanism: Khoom-web beams tiv thaiv loads los ntawm kev sib xyaw bending thiab shear; trusses hloov khoov lub sij hawm mus rau hauv axial nro thiab compression nyob rau hauv lub sab saum toj thiab hauv qab chords, nrog rau cov neeg hauv lub web nqa shear - tau txais cov khoom siv ntau dua.
Tus kheej- luj thiab ncua: Trusses yog sib dua nyob rau hauv nws tus kheej- hnyav nrog nruj dua, ua rau lawv zoo tagnrho rau ntev - ncua qauv; rau luv luv, khoom-web beams yog kev lag luam ntau dua.
Dab tsi yog cov txheej txheem sib koom ua ke rau steel trusses?
Welded pob qij txha: Muab cov txheej txheem zoo heev tab sis xav tau siab ntawm - qhov chaw vuam zoo.
Siab -lub zog bolted kev sib txuas: Ib qho yooj yim rau nruab thiab zoo- haum rau kev thauj mus los thiab kev lag luam sib dhos.
Gusset phaj kev sib txuas: Cov tswv cuab sib txuas ntawm lub phaj gusset thiab txuas nrog bolting lossis vuam.
Dab tsi yog hom ntoo khaub lig- ntu hom siv hauv steel trusses?
Lub kaum sab xis: Feem ntau siv rau hauv lub teeb yuag lossis me me - mus rau - nruab nrab -span qauv.
Cov raj hlau (lub voj voog / square hollow seem): Ua kom zoo nkauj nrog cua tsis kam, feem ntau siv rau hauv qhov chaw trusses.
H-sections lossis box sections: Haum rau hnyav-load lossis ntxiv-ntev- ncua cov qauv.
Yuav tiv thaiv corrosion thiab tiv thaiv hluav taws li cas rau steel trusses?
Kev tiv thaiv corrosion: Qhov saum npoo yuav tsum tau tawg - ntxuav kom tshem tawm cov xeb, ua raws li kev siv lub hnyav- lub luag haujlwm tiv thaiv - corrosion primer thiab topcoat, los yog kho nrog kub - dip galvanizing.
Kev tiv thaiv hluav taws: Siv tuab- zaj duab xis lossis nyias- zaj duab xis intumescent fireproof txheej rau steel qauv raws li cov cai raws li txoj cai kom ua tau raws li qhov ntsuas hluav taws kub.
