Rebar lub rooj zaum spacers txoj hauj lwm reinforcement steel grids thiab rebar meshes ntawm predetermined clearance heights ua ntej mus ua vaj tse. Los ntawm kev tuav cov pob zeb npog qhov tob, cov spacers no ua kom tag nrho cov rebar encapsulation, tiv thaiv cov txheej txheem steel raug, ya raws ntxov ntxov, thiab tom qab rebar oxidation.

Muab nyob rau hauv siab - ntom polyethylene (HDPE), polypropylene (PP), cementitious qhob, thiab steel configurations, cov khoom no haum rau hnyav rebar loads tsis tilting, slipping, los yog deflecting thaum lub sij hawm ua vaj tse pouring thiab mechanical vibration.

Cov yam ntxwv tseem ceeb ntawm cov khoom

Siab Load Capacity:Thick-cov phab ntsa rib qauv tiv thaiv crushing nyob rau hauv hnyav rebar tawb thiab qhov chaw ko taw tsheb.

Stable footprint:Cov phiaj dav dav thiab ntau- ceg teeb tsa tiv thaiv kev nkag mus rau hauv cov txheej txheem rwb thaiv tsev mos lossis cov av ntub dej subgrades.

Ntau-Cov Qhov Siab:Dual thiab quad-qhov siab geometry tso cai rau ib tus qauv spacer los npog ntau qhov kev qhia tshwj xeeb npog qhov tob (piv txwv li, 50mm / 75mm).

Concrete Bonding:Qhib -thav duab clip- ntawm cov qauv tsim thiab fiber ntau- cov pob zeb ua kom muaj zog tso cai rau cov slurry ntws tsis sib haum, tshem tawm cov huab cua voids lossis thermal expansion tsis sib haum.

Corrosion Resistance:Tsis yog-cov yas thiab cov pob zeb sib txawv uas tsis muaj xeb tshem tawm cov pob zeb xeb ntawm cov pob zeb sab nrauv.

FAQ

Q: Ua li cas tiaj tus- cov rooj zaum hauv qab yas rebar txawv ntawm tus qauv taw tes- ceg rooj zaum?

A: Pav ca- cov rooj zaum hauv qab nthuav dav cov qauv thauj khoom thoob plaws qhov chaw dav kom tiv thaiv kev tho cov mos mos, cov kab thaiv vapor, lossis cov ntaub thaiv rwb thaiv tsev. Taw tes - ceg rooj zaum yog npaj rau cov plywood nyuaj lossis steel formwork kom txo qhov pom qhov chaw ntawm qhov chaw tom qab stripping.

Q: Cov khoom siv yas puas tuaj yeem siv rau hauv hluav taws kub - ntsuas cov qauv ua vaj tse?

A: Rau cov hluav taws nruj heev- cov kev cai tiv thaiv (piv txwv li, cov kab hauv kab lossis siab -tier pej xeem tej yaam num), pob zeb spacers txuam lub ntsiab pouring zog yog pom zoo. Yas spacers tuaj yeem yaj nyob rau hauv cov cua kub hnyav, muaj peev xwm cuam tshuam kev tiv thaiv hauv zos.

Q: Qhov kev ncua deb yuav tsum tau khaws cia ntawm cov rooj zaum rebar?

A: Feem ntau qhov sib txawv ntawm 0.7 m txog 1.0 m raws qhov ntev ntawm rebar. Thinner bar diameters (# 3 / # 4) yuav tsum tau nyob ze dua (0.6 m txog 0.8 m) kom tshem tawm sagging hauv qab steel mesh hnyav.

Q: Puas yog pob zeb rebar cov rooj zaum sib raug zoo nrog cov pob zeb sib xyaw ua ke?

A: Yes. Quality concrete chairs are manufactured with low water-absorption mortar (compressive strength >= 50 MPa) uas txuas ncaj qha nrog cov pob zeb ua pob zeb, tuav cov yam ntxwv thermal expansion.

Q: Puas yog cov yas rebar spacers ruaj khov nyob rau hauv lub hnub ci sab nraum zoov ntev?

A: Export-qib yas spacers yog tsim nrog UV-inhibiting additives los tiv thaiv embrittlement thaum lub sij hawm ncua chaw ua hauj lwm cia ua ntej pouring.

Q: Lub sij hawm ua tus qauv piv rau kev cai -moulded spacers yog dab tsi?

A: Standard dimensions nkoj hauv 10 mus rau 15 hnub ua hauj lwm. Kev cai qhov siab profiles xav tau kev txhaj tshuaj tshiab feem ntau xav tau 25 mus rau 35 hnub rau pwm sim thiab ntau lawm.
