Tsis muaj qhov ruaj khov "siab tshaj plaws load-bearing" tus nqi rau 10-millimeteriav tempered, raws li nws nyob ntawm ntau yam tseem ceeb.
Lub ntsiab lus tseem ceeb: Dab tsi yog qhov load -cov kabmob muaj peev xwm nyob ntawm?
Lub load-cov kabmob muaj peev xwm ntawm cov iav tempered feem ntau txiav txim siab tsis yog los ntawm cov khoom siv "compressive zog" (vim nws nyuaj heev), tab sis los ntawm nws lub zog flexural thiab deflection (piv txwv li, tus nqi ntawm deformation). Cov yam tseem ceeb muaj xws li:
Txoj kev txhawb nqa: Qhov no yog qhov tseem ceeb tshaj plaws. Puas yog kev txhawb nqa ntawm tag nrho plaub sab? Kev txhawb nqa ntawm ob tog? Puas tseem muaj kev txhawb nqa los ntawm plaub lub ntsiab lus? Kev txhawb nqa zoo npaum li cas?
Qhov loj me (chaw): Qhov loj dua qhov dav (ntev thiab dav) ntawm lub khob, qhov tsawg dua nws cov load-cov kabmob muaj peev xwm txo qis geometrically. Ib qho 1-meter los ntawm 1-meter daim iav muaj peev xwm thauj khoom ntau dua li 2-meter los ntawm 2-meter daim iav.
Hom quab yuam: Nws puas yog ib qho kev faib khoom sib xws (xws li dej siab hauv lub thoob dej yug ntses) lossis cov khoom hnyav (xws li tus neeg sawv hauv nruab nrab)? Concentrated loads ua rau muaj kev sib tw ntau dua rau iav.
Kev siv ib puag ncig: Puas muaj kev poob siab lossis kev co? Puas yog qhov kub hloov pauv hnyav?
Kev nyab xeeb yam: Hauv engineering, kev nyab xeeb txaus yuav tsum tau sab laug. Feem ntau, qhov kev nyab xeeb yog siab heev (piv txwv li, ntau tshaj plaub zaug) kom ntseeg tau tias muaj kev nyab xeeb.
Kev siv qhov tseem ceeb nyob rau hauv cov xwm txheej zoo
Txhawm rau muab koj lub tswv yim intuitive, peb xav tias nyob rau hauv cov xwm txheej zoo tshaj plaws:
Kev them nyiaj yug txoj kev: Plaub sab yog ruaj khov rau ntawm ib lub tiaj tus thiab nruj ncej.
Hom quab yuam: Uniform load (qhov hnyav yog sib npaug sib npaug thoob plaws tag nrho cov iav).
Cov qauv kev nyab xeeb: Raws li kev paub dhau los hauv kev lag luam thiab cov qauv kev nyab xeeb dav dav.
Kev siv ntau yam rau kev thauj khoom -cov kabmob muaj peev xwm ntawm 10mm tempered iav:
Rau desktop, txee thiab lwm yam kev siv: Nws tuaj yeem dais 300 mus rau 500 kilograms ib square meter.
Rau kev siv xws li hauv pem teb thiab staircases: Xav txog qhov dynamic loads thiab cuam tshuam los ntawm tib neeg taug kev, qhov tsim load- bearing peev yuav siab dua, tab sis qhov tso cai deformation (deflection) yuav tsum nruj dua.
Piv txwv li:
Ib lub 10 hli tempered iav daim ntawm 1 meter los ntawm 1 meter, txhawb nqa ntawm tag nrho plaub sab, tuaj yeem tiv taus kwv yees li 300 txog 500 kilograms.
Ib daim ntawm tib lub khob ntsuas 2 meters los ntawm 1 'meter' yuav muaj peev xwm thauj khoom -cov kabmob uas poob rau kwv yees li 150 txog 250 kilograms. Vim tias qhov ncua sij hawm tau nce ob npaug, nws txoj kev khoov yuav tsis muaj zog heev.
Kev tshuaj xyuas ntawm cov ntawv thov tseem ceeb scenarios
1. Raws li lub iav desktop
Qhov xwm txheej: Feem ntau yog txhawb los ntawm plaub sab lossis plaub fab.
Load-cov kabmob muaj peev xwm: Muaj peev xwm txhawb nqa qhov hnyav ntawm cov khoom ntawm lub rooj noj mov thiab txawm tias qhov hnyav ntawm tus neeg laus zaum ntawm nws (tab sis qhov no tsis pom zoo). Qhov tseem ceeb nyob rau hauv hais tias cov ntsiab lus txhawb nqa yuav tsum ruaj, thiab cov npoo yog nyiam dua chamfered los yog tiv thaiv.
2. Raws li lub tank ntses / thoob dej yug ntses
Qhov xwm txheej: Qhov no yog ib yam khoom hnyav (dej siab).
Kev suav: Lub siab ntawm cov dej nce nrog qhov tob. Nyob rau hauv lub tank ntses nrog dej tob ntawm 50 centimeters, lub siab nyob rau hauv qab yog kwv yees li 0.05 kilograms ib square centimeter. 10mm tempered iav yog tag nrho muaj peev xwm tuav lub sab phab ntsa thiab hauv qab ntawm feem ntau tsev neeg ntses tank. Txawm li cas los xij, tus yuam sij rau kev thauj khoom- lub peev xwm ntawm lub thoob dej yug ntses yog nyob rau hauv cov txheej txheem kev sib txuas thiab kev tsim qauv es tsis yog lub zog ntawm ib daim iav. Thov nco ntsoov yuav cov khoom tsim los ntawm cov kws tshaj lij manufacturers.
3. Iav pem teb los yog stair treads siv raws li cov neeg taug kev
Qhov xwm txheej: Qhov no yog kev sib xyaw ua ke ntawm cov khoom hnyav (tib neeg ko taw trampling) thiab dynamic loads (thaum taug kev).
Load-cov kabmob muaj peev xwm: Qhov hnyav ntawm ib tus neeg laus (kwv yees li 70 txog 100 kilograms) yog ntau tshaj qhov txaus rau nws. Tab sis lub hauv paus ntawm kev tsim yog:
Tswj deflection: Tsis pom tseeb downward khoov yog xav tias thaum stepping rau nws.
Kev tiv thaiv-kev kho plam: Qhov saum npoo yuav tsum tau kho kom tiv thaiv- plam lub hom phiaj.
Ntau yam kev tiv thaiv: Laminated tempered iav feem ntau yog ua los ntawm ntau txheej iav. Txawm tias ib txheej tawg, lwm txheej tseem tuaj yeem muab kev txhawb nqa.
Cov lus ceeb toom txog kev nyab xeeb thiab cov lus pom zoo kawg
Tsis txhob kwv yees rau siab - cov xwm txheej txaus ntshai ntawm koj tus kheej: Yog tias koj npaj yuav siv 10 hli tempered iav rau hauv pem teb, ntaiv, cov qauv cantilevered loj, siab - qhov siab guardrails thiab lwm qhov chaw uas muaj kev nyab xeeb ntawm tus kheej, koj yuav tsum sab laj nrog tus kws tshaj lij kev tsim qauv lossis cov chaw tsim khoom siv iav.
Qhov tsis muaj zog ntawm tempered iav nyob rau hauv nws cov npoo thiab cov ces kaum: Lub zog ntawm tempered iav los ntawm compressive kev nyuaj siab ntawm nws nto. Thaum cov npoo los yog cov ces kaum raug ntaus los ntawm cov khoom tawv, nws muaj peev xwm ua rau tag nrho cov iav rau "kev ntxhov siab ploj" thiab tawg mus rau hauv cov khoom. Kev tiv thaiv tshwj xeeb yuav tsum tau muab rau cov ces kaum thiab cov npoo thaum thauj thiab teeb tsa.
Qhov kev xaiv zoo tshaj plaws yog laminated tempered iav: Rau txhua daim ntawv thov xws li hauv pem teb, guardrails, thiab ceilings, qhov kev nyab xeeb tshaj plaws yog siv laminated tempered iav. Nws yog tsim los ntawm ob lossis ntau daim iav tempered nrog PVB zaj duab xis sandwiched ntawm lawv. Txawm tias nws tawg, cov tawg yuav lo rau hauv zaj duab xis thiab yuav tsis poob, ua rau nws muaj kev nyab xeeb heev.
