Compression Rebar Couplers muab qhov kawg - mus rau - xaus kev thauj mus los rau kev txhawb nqa tuav uas feem ntau yog compressive quab yuam. Los ntawm kev tuav cov square ncaj ncaj- txiav bar kawg bearing nyob rau hauv lub siab - lub tes tsho steel, cov neeg kho tshuab splices kis compressive kev nyuaj siab ncaj qha los ntawm cov tub ntxhais rebar yam tsis muaj kev cia siab rau cov pob zeb sib txuas ntev los yog ncej puab splice congestion.
Tsim los rau cov kab ntau ntxiv, shear phab ntsa, lub hauv paus, thiab precast qhob sib txuas, kawg -cov kabmob compression couplers txo cov neeg coob coob, txo qis steel noj, thiab ua kom yooj yim rau lub tawb fabrication nyob rau hauv siab -cov khoom siv ntom ntom.
Cov yam ntxwv tseem ceeb ntawm cov khoom
Xaus -Bearing Load Transfer:Cia siab rau kev sib cuag ntawm lub cev ncaj qha ntawm square- txiav bar xaus, ua tiav 100% compressive load hloov.
Congestion txo:Tshem tawm cov ceg ntev ntev, tso tawm qhov chaw rau kev sib sau ua ke thiab kev sib koom ua ke.
Tsis xav tau threading (bolted hom):Shear- cov kev xaiv ntsia liaj qhov rooj tso cai rau kev teeb tsa ncaj qha nrog cov txheej txheem cuam tshuam wrenches, zam kev ua haujlwm ntawm cov xov.
Compact Tes Tsho Profile:Ua kom meej npog qhov sib nrug tsis tu ncua yam tsis hloov qhov ntev formwork.
Visual Inspection Window:Lub chaw soj ntsuam hauv nruab nrab tso cai rau kev txheeb xyuas tam sim ntawm qhov sib txawv ntawm qhov bar thiab qhov chaw zaum kom raug ua ntej kaw.

Qib & Standards
SIB 318:Ua tau raws li Hom 1 thiab Hom 2 txhua yam splice xav tau rau compression.
TS EN 1992-1-1 (Eurocode 2):Ua raws li mechanical reinforcement connector specifications.
ASTM A1034 Txuj:Standard Test Methods Test Mechanical Splices for Steel Reinforced Bars.
ISO 15835:Hlau rau kev txhim kho ntawm cov pob zeb ua ke - Reinforcement couplers rau mechanical splices of bars.
Daim ntawv thov
Precast Concrete Kem & Piers:Hloov hnyav ntsug loads nruab nrab ntawm cov khoom precast nrog tsawg kawg nkaus thickness.
High-Rise Core Walls:Structural shear wall vertical rebar continuity qhov twg lap splices ua rau rebar congestion.
Choj Substructures:Pier caps, caissons, thiab hnyav foundation mats raug rau axial compression.
Retaining Walls & Foundations:Splicing loj- txoj kab uas hla (#11 - #18 / 32mm - 57mm) qhov twg lap splicing tsis yog-raws li los yog impractical.
Kev teeb tsa
Kev npaj Bar End:Pom- txiav rebar xaus rau 90-degree square ntsej muag (<1.5 degrees angular deviation). Remove burrs, rust, scale, and concrete slurry.
Coupler Positioning:Xaub lub tes tsho compression hla lub qis qis ruaj khov kom txog thaum nws mus txog qhov chaw nres tsheb sab hauv lossis cov neeg pov thawj kab.
Upper Bar Alignment & Rooj:Txo lub sab sauv rebar rau hauv lub tes tsho. Xyuas kom cov hlau ncaj nraim -rau-hlau kawg bearing tiv thaiv qis bar nrog xoom huab cua sib txawv.
Tightening / ruaj ntseg:Rau shear-bolt qauv, nruj nreem bolts raws sij hawm siv ib tug cuam tshuam wrench kom txog rau thaum tag nrho cov ntsia liaj qhov rooj hau shear tawm ntawm lub torque theem.
Kev soj ntsuam zaum kawg:Tshawb xyuas qhov chaw zaum hauv qhov chaw pom qhov pom thiab xyuas tias txhua lub taub hau ntsia hlau tau txiav tawm kom huv.
Zoo & Kev Xeem
Batch Khoom Traceability:Raw steel kub cov lej sau nrog daim ntawv pov thawj zeb xeem (MTC) raws li EN 10204 3.1.
