Log rebar spacers (tseem hu ua ncig lossis yas nplhaib spacers) tuav cov pob zeb sib xws nyob ib ncig ntawm cov hlau tuav hauv cov qauv ntsug thiab kab rov tav. Lub voj voog geometry muab 360-degree stability nyob ib ncig ntawm lub rebar, kom lub tawb tuav meej meej clearance ntawm formwork panels thaum lub sij hawm tso steel, tawb qis, thiab pob zeb pouring.

Tsim los ntawm kev txhaj tshuaj- molded siab- ntom polyethylene (HDPE) los yog polypropylene (PP), cov chav no muaj cov kab nrib pleb uas tuav cov kab uas hla tshwj xeeb kom ruaj ntseg yam tsis muaj slippage. Cov ntsiab lus sib txuas sab nraud txo qhov hneev taw tiv thaiv kev ua haujlwm, tiv thaiv kev tshaj tawm -pob dab lossis pob zeb los ntshav.

Cov yam ntxwv tseem ceeb ntawm cov khoom

360-Degree Concentric Clearance:Radial tsim tuav cov pob zeb sib xws tsis hais lub tawb sib hloov lossis kev txav mus rau sab nraud thaum muab tso rau.

Internal xauv lub puab tsaig:Saj zawg zog sab hauv grips haum raws li lub rebar txoj kab uas hla ntau yam thaum tiv thaiv axial hloov nyob rau hauv vibration.

Yam tsawg kawg nkaus Surface Contact:Tapered txheej fins txwv qhov chaw tiv tauj nrog shuttering panels, khaws cov hniav zoo nkauj lossis cov pob zeb ua kom tiav.

Siab Load Capacity:Engineered structural ribs tiv thaiv radial compression thaum lub sij hawm ua vaj tse, dej siab, thiab formwork sib cuag.

Chemical & Corrosion Resistance:Tsis yog -reactive polymer muaj pes tsawg leeg tiv thaiv xeb staining, ya raws ingress, thiab alkaline degradation nyob rau hauv cov pob zeb matrices.

Qhib Flow Profile:Cov tswv yim qhib tso cai rau aggregate thiab cement slurry ntws los ntawm lub log spacer, tiv thaiv qhov tsis muaj dab tsi lossis honeycombing.

FAQ

Q: Yuav ua li cas lub log rebar spacers tiv thaiv slipping ntawm ntsug rebar tawb?

A: Internal locking puab tsaig flex qhib thaum lub sij hawm ntxig thiab lub caij nplooj ntoos hlav rov qab nyob ib ncig ntawm lub bar profile. Parallel gripping ribs exert nruam radial nro, tswj txoj haujlwm ruaj khov txawm tias thaum lub tawb txav vertically.

Q: Puas yuav cov yas log spacers ua rau qhov chaw tsis zoo ntawm cov pob zeb tawg?

A: Tapered cov lus qhia sab nrauv txo qhov chaw sib cuag nrog cov chaw ua haujlwm. Cement slurry tag nrho encapsulates lub spacer npoo thaum lub sij hawm compaction, tiv thaiv ncej- strips nto kab los yog hollow hnab ris.

Q: Cov log spacers puas haum rau dhuav pawg tawb?

A: Yog. Log spacers center cylindrical steel tawb nyob rau hauv excavated shafts, tso cai rau cages kom swb down smoothly tsis dragging av rau hauv lub pob zeb qhov chaw.

Q: Ua li cas qhov kub hloov pauv cuam tshuam rau lub log yas spacer kev ua tau zoo?

A: High-qib HDPE / PP polymers tiv taus txias embrittlement mus rau -20℃thiab tswj cov txheej txheem nruj nyob rau hauv ambient kub txog li +70℃thaum lub sij hawm ua vaj tse hydration.

Q: Lub log spacers puas tuaj yeem siv rau ntawm epoxy-coated lossis stainless hlau rebar?

A: Yog. Lub ntsej muag yas zoo yuav tsis khawb, nti, lossis puas tsuaj tiv thaiv epoxy txheej los yog cov zinc txheej txheej ntawm galvanized rebar.

Q: Dab tsi yog lub sij hawm txhuas txhuas rau kev txiav txim ntim khoom?

A: Standard catalog sizes nkoj hauv 10-15 hnub. Kev cai qhov ntev yuav tsum tau txhaj tshuaj pwm tshiab feem ntau xa tuaj tsis pub dhau 25-35 hnub raws li kev pom zoo kos duab.
