Steel Structure Choj Truss

Kev teeb tsa thiab kev sib txuas ntawm cov qauv steel choj trusses yog cov kev sib txuas tseem ceeb hauv kev tsim choj thiab kev tsim kho, uas muaj feem xyuam rau kev ruaj ntseg, kev nyab xeeb, kev pab lub neej, thiab kev lag luam ntawm tus choj. Cov hauv qab no yog cov ntsiab lus tseem ceeb thiab cov qauv tsim rau kev teeb tsa thiab kev sib txuas ntawm steel qauv choj trusses:

(1) Span thiab load tsom xam

Span xam: Cov txheej txheem ntawm tus choj trusses yuav tsum xub txiav txim siab raws li qhov ntev ntawm tus choj, thiab qhov loj me yog tus yuam sij rau kev tsim. Ua cov qauv kev soj ntsuam raws li kev khiav tsheb khiav, choj dav dav, thiab cov khoom thauj (xws li tsheb thauj khoom, thauj neeg taug kev, cua thauj khoom, thiab lwm yam) kom ntseeg tau tias lub truss tuaj yeem faib cov khoom no zoo.

Load faib: Choj truss tsim yuav tsum xav txog yuav ua li cas sib txawv ntawm loads (xws li nyob loads, tuag loads, kub loads, thiab lwm yam) yog muab faib rau hauv lub truss, thiab xam qhov tsim nyog qhov ntev ntawm lub qhov ntev thiab cov hauj lwm ntawm lub structural tsom xam.

(2) Geometric duab thiab kev npaj ntawm truss

Kev sib raug zoo ntawm tus choj hla thiab qhov tob: Cov choj loj loj feem ntau tau teeb tsa hauv cov duab geometric xws li daim duab peb sab, duab plaub, lossis daim duab peb sab inverted. Cov hom trusses feem ntau suav nrog cov qauv trusses thiab spatial trusses.

Kev tsim cov trusses yuav tsum ua tau raws li cov kev xav tau: rau cov txuas txuas ntev, ntau lub tshuab truss feem ntau yuav tsum muaj kev txhawb nqa; Rau cov choj dav dav, nws yuav tsum tau ntxiv cov trusses thib ob lossis ntxiv dag zog rau kev tsim ntawm lub ntsiab truss.

Kev txhawb nqa txoj haujlwm xaiv: Kev txhawb nqa ntawm lub truss feem ntau yog teem rau ntawm ob qho kawg lossis hauv nruab nrab ntawm tus choj (yog tias nws yog tus choj ntau qhov) kom ntseeg tau tias cov qauv kev ntxhov siab. Daim ntawv txhawb nqa tuaj yeem kho cov bearings, hinged bearings, thiab lwm yam.

(3) Kev sib xyaw ua ke ntawm truss thiab choj lawj qauv

Lub truss feem ntau yog qhov tseem ceeb ntawm kev thauj khoom ntawm tus choj sab saud, thiab nws cov kev sib xyaw nrog cov choj lawj yuav tsum muaj kev npaj tsim nyog ntawm kev txhawb nqa cov ntsiab lus thiab kev sib txuas los xyuas kom meej tias cov load ntawm tus choj lawj tuaj yeem xa mus tau zoo. truss, thiab ces kis tau mus rau kev txhawb nqa ntawm tus choj los ntawm ntau yam ntawm cov truss.

(4) Qhov siab thiab qhov tob ntawm tus choj truss

Qhov siab thiab qhov tob ntawm lub truss muaj feem xyuam rau cov kabmob muaj peev xwm thiab nruj ntawm tus choj. Tsim nyog truss qhov siab pab txuas hniav kom zoo stability nyob rau hauv load. Qhov siab ntawm lub truss yog feem ntau yoog raws li kev ncua, kev thauj khoom, thiab kev tsim qauv ntawm tus choj.

(1) Node kev twb kev txuas

Vuam kev sib txuas: Vuam yog ib qho kev sib txuas uas siv ntau hauv cov qauv steel choj trusses, tshwj xeeb tshaj yog nyob rau ntawm qhov sib txuas. Vuam yuav muab cov kev sib txuas siab thiab lub zog sib txuas, haum rau qhov uas tau siv rau cov voos xwm txheej loj lossis lwm yam tsis zoo li cov pob zeb.

Bolt kev twb kev txuas: Bolt kev twb kev txuas yog ib txoj kev sib txuas, haum rau ntau qhov chaw ntawm cov choj trusses, tshwj xeeb tshaj yog thaum cov nodes yuav tsum tau disassembled los yog khaws cia. Lub zog muaj zog bolts tuaj yeem muab kev sib txuas muaj zog thiab yooj yim rau kev tsim. Bolt txuas feem ntau yog siv rau ntsug thiab kab rov tav ceg ntawm cov txuas hniav.

Rivet kev twb kev txuas: Rivet kev twb kev txuas yog tseem siv nyob rau hauv ib co qub steel qauv txuas hniav. Riveted kev sib txuas tsis hloov pauv raws li kev sib txuas ntawm vuam thiab bolted, tab sis lawv tseem siv tau rau qee cov qauv qub qub.

(2) Node tsim

Cov kev txhawb nqa yooj yim: Cov nodes txhawb nqa yooj yim feem ntau yog siv rau hauv cov txuas hniav uas yuav tsum tau muaj kev thauj khoom unidirectional, feem ntau ntawm ob qho kawg ntawm tus choj truss. Cov kev txhawb nqa yooj yim txuas nrog rau lwm qhov ntawm tus choj los ntawm kev txhawb nqa bearings, ua kom yooj yim rau kev hloov ntawm cov khoom thauj.

Kho cov nodes: Rau qhov chaw uas dais loj dabtsi yog khoov lub sij hawm, choj truss nodes tej zaum yuav raug tsim raws li taag nodes. Cov nodes ruaj khov tuaj yeem ua rau kom muaj kev ruaj ntseg ntawm cov qauv thiab tsim nyog rau lub ntsiab truss ib feem ntawm cov txuas hniav.

Articulated nodes: Nyob rau hauv cov qauv tsim uas yuav tsum tau tso cai rau truss tig los yog loj deformation, articulated nodes yuav siv tau. Articulated kev sib txuas tuaj yeem txo qhov nruj ntawm cov qauv, tso cai rau nws hloov mus rau deformations los ntawm yam xws li kub thiab load hloov.

(3) Kev sib txuas ntawm truss thiab kev txhawb nqa

Kev txhawb nqa ntawm lub truss yog ib qho tseem ceeb txuas ib feem ntawm tus choj truss. Kev tsim ntawm kev txhawb nqa kev sib txuas yuav tsum ua kom muaj kev ruaj ntseg ntawm tus choj hauv qab thauj khoom. Cov ntaub ntawv ntawm cov kabmob tuaj yeem muab faib ua cov kabmob ruaj khov, cov kabmob hinged, thiab cov kabmob dov. Kev xaiv ntawm cov bearings yuav tsum coj mus rau hauv tus account hom load tus choj yog raug rau, geological tej yam kev mob, thiab tsim yuav tsum tau ntawm tus choj.
