Hauv kev lag luam LED zaub, yuav luag txhua kab lus qhia rau koj tias kev tsim thermal txiav txim siab txog kev ua neej, pixel suab txiav txim siab meej, thiab tus nqi tshiab txiav txim siab lub koob yees duab kev ua haujlwm. Qhov lawv tsis tshua hais yog seb qhov screen nyob hauv huab cua. Ib lub 500 × 500mm qev txee hnyav dua 8 kilograms; ib lub phab ntsa LED sib sau ua ke tuaj yeem dai ntau pua kilograms ntawm lub truss, ob peb meters saum cov neeg tuaj saib nrog lawv txhais tes hauv huab cua. Qhov kev sib txawv ntawd yog qhov tsab xov xwm no hais txog. Peb tau npog steel sub-thav duab, cov ntaub ntawv txee, thiab cov kev pabcuam pem hauv ntej / nraub qaum tsim lwm qhov ntawm qhov chaw no. Cov khoom no tsom tshwj xeeb rau kev ruaj ntseg dai - dab tsi tshwm sim thaum koj ncua kev tso saib rau tib neeg.
1. Lub kaw lus rigging yeej tsis nqa qhov hnyav ntawm qhov screen xwb
Qhov feem ntau yuam kev hauv LED phab ntsa rigging yog sizing lub hardware rau lubliab qab txee hnyav. Lub kaw lus raug tshem tawm yuav tsum tau ua tiag tiag:
- Tuag load- qhov sib dhos hnyav ntawm cov txee ntxiv rau cov qauv tsim;
- Add-on loads- dai banners, teeb pom kev zoo tuav, suab sau, cable khiav, lossis nkag mus rau platform;
- Dynamic rog- thawb thiab rub raws li phab ntsa yog log nrog ib tug dolly, huab cua siab nyob ze ntawm lub suab nrov arrays, cuam tshuam los ntawm ib tug ntog ua yeeb yam, los yog ib tug wardrobe rack nudged rau hauv qab kab;
- Acceleration loads- los ntawm kev ua raws li qhov chaw booms, lub koob yees duab crane txav, los yog rigging raug repositioned mid-show.
Ib lub txee 8-kilogram ntawm lub viav vias dynamic hlua tuaj yeem sau npe ib ntus rub ntawm 40 kilograms lossis ntau dua ntawm ib qho taw tes. Riggers hu qhov piv txwv nodynamic yam. Tsis quav ntsej nws yog ib qho ntawm feem ntau ua rau "nws raug ntsuas rau qhov hnyav" xwm txheej.
2. Qhov kev nyab xeeb yog tus lej, tsis yog kev xav
Hauv kev rigging kev tshaj lij, "nws xav tias muaj zog txaus" tsis yog lus teb. Kev pom zoo thoob plaws kev lag luam yog:
- Rau txhua yam raug tshem tawm ntawm tib neeg: ib qho kev nyab xeeb yam tsawg kawg nkaus 8: 1 (10: 1 nyob rau hauv ntau European jurisdictions);
- Rau txheem truss teeb pom kev zoo / video loadsyam 5:1;.
- Rau integrated mounting systems (brackets/IMS).: yam tsawg kawg yog 4: 1 rau ib lub bracket, txheeb xyuas plaub qhov kev xeem ywj pheej.
- Hauv cov ntsiab lus siv tau: yog tias koj cov qauv dai yuav tsum nqa 300 kilograms ntawm cov khoom sib dhos, cov khoom siv rigging yuav tsum tau ntsuas rautsawg kawg yog 1,500 kgraws li txoj cai 5: 1, nrog rau txhua tus neeg dai taw tes qhov loj me rau nws qhov sib koom ntawm cov khoom ntawd - tsis txhob mus rau "nws nkaus xwb
- hnyav 8 kilos" kwv yees ib lub txee.
3. Kev faib khoom thauj khoom: vim li cas yim lub ntsiab lus dai tuaj yeem ua rau muaj kev phom sij ntau dua li plaub
Counterintuitively, ntxiv cov ntsiab lus dai tsis tas yuav ua rau dai phab ntsa LED muaj kev nyab xeeb dua, thiab tuaj yeem ua rau nws tsis muaj kev nyab xeeb. Rigging engineers hu qhov noload faib teeb meem:
- Symmetrical ob-los yog plaub-point hangs: Txhua qhov taw qhia ntawm qhov hnyav tag nrho tuaj yeem suav tau meej, nrog qee qhov kev ywj pheej rau phab ntsa kom qaij hauv qab nws qhov hnyav.
- Rau, yim, los yog kaum taw tes hangs: Yog hais tias lub truss los yog hoists zaum txawm 1-2 millimeters tawm ntawm theem, ib los yog ob lub ntsiab lus yuav siv sij hawm yuav luag tag nrho cov load thaum tus so zaum slack - muab kev ntxhov siab nyob rau hauv cov ntsiab lus loaded deb tshaj li qhov kev ntsuam xyuas ib leeg.
Aluminium tuag-cam khwb cia txee muaj cov txheej txheem rigidity. Yog hais tias daim duab peb sab hanging tabs siv los preload lub thav duab, koj tuaj yeem hneev lub ntsej muag phaj, deform lub xauv mechanism, los yog nkees ntawm kev sib cuam tshuam clip. Tias yog vim li cas lub dai layout yuav tsum tau teem rau ntawm theem tsim, tsis improvised nrog eyeball kwv yees tom qab lub tsheb tuaj txog.
4. Cov khoom siv uas ua los yog tawg ib daig
Txawm tias muaj cov khoom ua tau zoo, kev txhim khu kev ntseeg tau nqis los rau plaub yam khoom siv:
- Pair ntawm ib nrab couplers (tsis yog caij nplooj ntoos hlav clips).- tib txoj kev lees txais clamp rau tus qauv yeeb nkab / truss, nrog rau tus pin xauv tag nrho;
- Turnbuckles- kev kho kom zoo rau qib thiab kev sib tw tom qab phab ntsa nce;
- Kev ruaj ntseg cable los yog daim ntawv cog lustxuas rau ibywj siab kiag lithauj tog rau nkoj taw tes, yog li cov phab ntsa nyob twj ywm nyob rau hauv qhov chaw yog ib tug thawj point tsis;
- Lub hom phiaj-ua LED dai tuav lossis IMS ntasmatched rau lub txee dai-qhov sib nrug thiab qhov nruab nrab ntawm lub ntiajteb txawj nqus.
Tsis muaj kev ruaj ntseg cable, siv lub caij nplooj ntoos hlav-loaded "ceev clamps" es tsis txhob ntawm ib nrab couplers, thiab turnbuckles tsis muaj xauv ceev tshwm sim dua nyob rau hauv cov ntaub ntawv tshwm sim tiag tiag, thiab tag nrho peb yog zam yuam kev.
5. Ua rigging ib feem ntawm koj qhov kev thov rau cov lus hais - tsis yog teb improvisation
Muaj ntau cov rigging tsis ua hauj lwm taug qab tsis yog blunt txiaj ntawm cov cuab yeej, tab sis rautsim-theem omissions. Thaum koj nug txog LED zaub, nug cov chaw tsim khoom rau:
Ib tug dai-point layout nrogassembled hnyav thiab qhov nruab nrab ntawm lub ntiajteb txawj nquscim;
Qhov tsawg kawg nkaus thiab siab tshaj plaws ua haujlwm load txwv ib qho kev sib txuas mounting bracket;
Txawm hais tias cov txee txhawb kev sib cuam tshuam kev sib txuas kev nyab xeeb (yog li yog tias lub txee lub ntsiab lus dai tsis ua haujlwm, nws cov neeg nyob ze tsis ua cascade);
Seb cov phab ntsa sib dhos taupov thawj-load kuaj(rub mus rau tag nrho cov tsim load rau lub sij hawm uas tsis muaj kev ntsuas deflection).
Anchoring cov ntsiab lus hauv daim ntawv cog lus hloov rigging kev nyab xeeb los ntawm kev cia siab rau hauv ib qhoHoobkas kuaj xyuas specification.
Kaw kev xav
Saib tom qab mortems los ntawm dai LED phab ntsa teeb meem thiab lub hauv paus ua rau tsis tshua muaj LED technology. Nws yog ib qho kev nthuav dav rigging: ib qho unaccounted dynamic load, ib tug tsis muaj kev ruaj ntseg cable, los yog ib tug sib koom misaligned multi-point hang. Qhov kho tsis yog qhov screen kim dua. Nws yog kho rigging raws li ib tugkev qhuab qhia: Cov ntaub ntawv teev cov ntsiab lus thauj khoom, kev ruaj ntseg cables ntawm txhua lub txee, cov thauj tog rau nkoj ywj pheej, thiab cov kws ua haujlwm rigging tshuaj xyuas cov phiaj xwm ua ntej ib lub txee tawm hauv av. Txhua tus neeg sawv cev hauv qab tsim nyog tau txais qhov kev tshuaj xyuas tsawg kawg ib zaug.
