Taw qhia
Nyob rau hauv precast vaj huam sib luag ntau lawm, spacers yog siv los tuav rebar txoj hauj lwm thiab pob zeb npog thickness. Yog tias xaiv qhov tsis raug cai, lub rebar yuav txav tau thaum lub sij hawm nchuav los yog kev co, ua rau lub hau tsis txaus, tsis sib npaug ntawm lub thickness, raug rebar, los yog tom qab rework.
Rau precast phab ntsa vaj huam sib luag, façade panels, sandwich panels, thiab nyias cov ntsiab lus, spacer xaiv yuav tsum tsis txhob nyob ntawm qhov siab ib leeg. Rebar txoj kab uas hla, vaj huam sib luag thickness, load peev xwm, pwm nto, pouring txoj kev, thiab kev co tej yam kev mob yuav tsum tau xav txog. Kab lus no piav qhia yuav ua li cas xaiv qhov zoo spacers rau precast qhob panels.
Vim li cas Spacers teeb meem hauv Precast Concrete Panels
Spacers ua lub luag haujlwm tseem ceeb hauv kev tsim cov vaj huam sib luag precast. Lawv khaws cov rebar los yog welded mesh nyob rau hauv qhov tseeb txoj hauj lwm ua ntej thiab thaum lub sij hawm casting. Los ntawm kev tuav cov pob zeb uas yuav tsum tau ua kom tuab, spacers pab txo cov teeb meem xws li raug rebar, nto tawg, corrosion kuj, thiab kho cov hauj lwm tom qab demolding. Rau precast phab ntsa vaj huam sib luag, façade panels, sandwich panels, thiab nyias cov pob zeb, xaiv qhov zoo spacers pab txhim kho cov khoom sib xws, nto zoo, thiab ntev -lub sij hawm durability.
Pib nrog Qhov Yuav Tsum Tau Ua Npuas Ncauj
Lub hau npog yog hais txog qhov kev ncua deb ntawm lub rebar nto thiab sab nrauv ntawm lub vaj huam sib luag. Nws tiv thaiv qhov kev txhawb zog los ntawm kev ya raws, corrosion, hluav taws kub, thiab kev puas tsuaj saum npoo. Nyob rau hauv precast qhob vaj huam sib luag ntau lawm, spacer qhov siab yuav tsum nco ntsoov xaiv raws li qhov yuav tsum tau ua vaj tse npog nyob rau hauv qhov project drawings.
Yog li ntawd, qhov siab spacer yuav tsum tsis txhob xaiv los ntawm tus cwj pwm lossis kev ua haujlwm dhau los. Ua ntej ntau lawm, xyuas cov duab kos, paub meej tias qhov yuav tsum tau npog tuab, thiab phim qhov siab spacer rau qhov tseeb vaj huam sib luag tsim. Qhov no yuav pab kom ntseeg tau tias qhov kev txhawb nqa muaj kev tiv thaiv zoo.
Xaiv qhov raug Spacer Qhov siab
Spacer qhov siab ncaj qha cuam tshuam rau txoj haujlwm rebar thiab qhov kawg pob zeb npog tuab. Hauv kev tsim cov vaj huam sib luag precast, txawm tias qhov siab me me sib txawv tuaj yeem ua rau tsis sib xws ntawm cov thickness tom qab demolding.
Common spacer heights suav nrog15mm, 20mm, 25mm, 30mm, 40mm, thiab 50mm. Lower spacers feem ntau yog siv rau nyias precast panels los yog cov khoom uas yooj yim layouts, thaum thicker precast panels los yog structural panels tej zaum yuav xav tau ntau dua spacers kom tau raws li cov kev cai npog thickness.
Xyuas Spacer Load Capacity
Spacers yuav tsum tsis tsuas yog ua tau raws li qhov yuav tsum tau npog qhov siab, tab sis kuj muaj peev xwm thauj khoom txaus los txhawb qhov kev txhawb nqa thaum lub sijhawm teeb tsa, nchuav, thiab kev co. Rau hnyav rebar tawb, ntom welded mesh, ob -txheej txheej, phab ntsa loj, los yog hnyav hnyav precast ntsiab, muaj zog thiab ruaj khov spacers yuav tsum tau xaiv.
Yog tias lub peev xwm thauj khoom tsis txaus, lub spacer yuav deform, tawg, dab dej, lossis qaij thaum tsim khoom. Qhov no tuaj yeem ua rau qhov tsis sib xws ntawm cov thickness tom qab demolding thiab ua rau muaj kev pheej hmoo ntawm cov rebar raug, tawg, corrosion, thiab kho ua hauj lwm. Yog li ntawd, spacers nrog cov khoom tsim nyog lub zog, lub hauv paus kev txhawb nqa txaus, thiab cov qauv ruaj khov yuav tsum raug xaiv los pab faib cov khoom thauj thiab ua kom lub zog ntawm txoj haujlwm.
Sib piv cov Spacer Hom rau Vaj Huam Sib Luag Tsim
Log Spacers
Lub log spacersfeem ntau yog siv rau ntsug reinforcement nyob rau hauv precast phab ntsa panels. Lawv tuaj yeem txuas mus rau lub rebar thiab pab tswj qhov kev ncua deb ntawm qhov cuab lub zog thiab cov pwm nto, ua rau lawv haum rau phab ntsa panels, façade panels, thiab lwm yam ntsug rebar layouts.
Chair Spacers
Lub rooj zaum spacers, tseem hu ua rebar cov rooj zaum, feem ntau yog siv los txhawb cov kab rov tav welded mesh lossis rebar txheej. Lawv txhawb kev txhawb nqa los ntawm hauv qab no thiab feem ntau yog siv hauv cov slabs, tiaj tiaj, thiab kab rov tav cam khwb cia precast ntsiab.
Kab Spacers
Kab spacers lossis bar spacers yog tsim rau kev txhawb nqa rebar lossis welded mesh hla thaj tsam ntev. Thaum xav tau kev txhawb nqa tas mus li tsis yog ib qho - taw tes txhawb nqa, kab spacers pab ua kom txoj hauj lwm txhawb nqa kom ruaj khov.
Qhob Spacers
Qhob spacerstuaj yeem siv rau cov ntsiab lus precast uas xav tau cov khoom sib xws, hluav taws kub, lossis ua raws li qhov project specifications. Lawv cov khoom yog nyob ze rau lub pob zeb nws tus kheej, ua rau lawv tsim nyog rau tej yaam num uas yuav tsum tau siab dua rau kev npog zoo thiab ntev - lub sij hawm durability.
Xav txog Rebar Diameter thiab Mesh Layout
Thaum xaiv spacers rau precast qhob panels, lub rebar txoj kab uas hla thiab mesh layout yuav tsum tau xyuas kom zoo zoo. Qhov loj me me los yog qhib qhov loj ntawm lub spacer yuav tsum phim lub rebar txoj kab uas hla.
Rau welded mesh, xyuas qhov sib nrug mesh thiab hla cov ntsiab lus ua ntej xaiv hom spacer. Lub spacer yuav tsum haum lub mesh kom tsis txhob thawb lub rebar tawm ntawm txoj hauj lwm. Yog hais tias qhov kev txhawb zog yog tuab, xaiv spacers uas yooj yim rau nruab thiab tsis cuam tshuam nrog cov kab nyob ze.
Spacer spacing kuj tseem ceeb. Cov vaj huam sib luag loj, hnyav dua, lossis thaj chaw dav mesh feem ntau xav tau cov ntsiab lus txhawb nqa ntau dua. Kev sib raug zoo pab ua kom lub zog ruaj khov thoob plaws hauv cov txheej txheem tsim khoom.
Xav txog vaj huam sib luag Thickness thiab Deg yuav tsum tau
Ua ntej xaiv spacers, xyuas lub thickness ntawm lub precast vaj huam sib luag. Cov vaj huam sib luag nyias muaj qhov ua siab ntev rau qhov tsis raug, yog li txawm tias qhov me me qhov siab qhov sib txawv tuaj yeem cuam tshuam rau txoj haujlwm rebar, pob zeb npog tuab, thiab qhov kawg vaj huam sib luag zoo.
Rau façade panels, nthuav phab ntsa panels, thiab architectural precast ntsiab, spacers yuav tsum tsis tsuas yog pab txhawb lub zog tab sis kuj yuav tsum tsis txhob tso tawm cov cim pom, nto defects, los yog tsis muaj zog cov ntsiab lus tom qab demolding. Yog tias cov duab spacer, cov khoom siv, lossis txoj haujlwm tsis haum, nws yuav cuam tshuam rau qhov ua tiav thiab txhim kho kev ua haujlwm.
Yog li ntawd, architectural precast panels yuav tsum siv spacers uas tuaj yeem tswj lub npog tuab kom raug thaum ua kom pom qhov chaw huv si. Kev xaiv spacer yuav tsum xav txog vaj huam sib luag thickness, rebar txheej txoj hauj lwm, thiab nto tiav yuav tsum ua ke.
Xaiv cov khoom siv Spacer txoj cai
Cov khoom siv spacer yuav tsum phim lub vaj huam sib luag tsim, kev thauj khoom, thiab ib puag ncig tsim khoom. Cov ntaub ntawv sib txawv ua haujlwm sib txawv thaum lub sij hawm casting, vibration, demolding, thiab ntev - kev pab cuam lub sij hawm.
Thaum xaiv cov khoom siv spacer, xav txog:
Rebar hnyav thiab spacer load peev
Vaj huam sib luag thickness thiab qhob npog
Sab hauv lossis sab nraum zoov raug
Kev tiv thaiv hluav taws kub
Qhov yuav tsum tau ua
Project specifications
Muaj pes tsawg tus Spacers xav tau rau Precast Panels?
Tus naj npawb ntawm spacers yuav tsum tau rau precast qhob ntsiab nyob ntawm seb qhov loj me, rebar hnyav, mesh layout, spacer hom, load peev xwm, thiab yuav tsum tau cov pob zeb npog thickness. Rau cov ntsiab lus me me los yog lub teeb, cov ntsiab lus txhawb nqa tsawg dua yuav txaus yog tias lub mesh khov kho thiab khi zoo. For large wall panels, façade panels, sandwich panels, or densely reinforced elements, more spacers are usually needed to prevent rebar sagging or uneven cover thickness.
Spacer layout yuav tsum tau txiav txim siab raws li qhov project drawings, qhov loj me, kev tsim kho kom zoo, thiab cov qauv zoo ntawm lub Hoobkas. Ua ntej nchuav, cov neeg ua haujlwm yuav tsum xyuas seb cov spacers puas sib npaug, ruaj khov, thiab tuaj yeem txhawb nqa qhov kev txhawb nqa tsis tu ncua. Rau kev rov ua cov khoom ua ntej, qhov sib npaug ntawm qhov sib npaug thiab qhov chaw ruaj khov zoo pab txo qis qhov sib txawv thiab kho ua haujlwm tom qab demolding.
Xaus
Xaiv spacers rau precast qhob slabs koom nrog ntau dua li tsuas yog xav txog qhov siab. Qhov tsim nyog spacer yuav tsum tau ua raws li qhov yuav tsum tau ua cov pob zeb ua kom tuab, qhov kev txhawb nqa bar txoj kab uas hla, slab thickness, cov xwm txheej thauj khoom, cov khoom siv spacer, thiab cov txheej txheem tsim khoom.
Ua ntej muab ib qho kev txiav txim ntau, nco ntsoov xyuas cov duab kos, qhov cuab yeej cuab tam, qhov siab qhov siab, thiab qhov yuav tsum tau ua. Yog hais tias tus qauv slab yog unconventional, xaiv rau kev cai -ua spacers tej zaum yuav yog qhov zoo dua kev daws teeb meem.
