Crimping rebar couplers koom nrog reinforcing steel tuav los ntawm txias -swaged mechanical deformation yam tsis tas yuav threading, nplaim taws kub, los yog qhov chaw vuam. Lub tes tsho seamless carbon steel swb hla ob qhov kawg ntawm cov rebar kawg, thiab lub tshuab nqa hydraulic xovxwm compresses lub tes tsho radially xauv rau hauv rebar deformation tav. Qhov no tsim lub siab - lub zog mechanical splice uas hloov cov qauv thauj khoom ncaj qha los ntawm cov hlau.

Cov yam ntxwv tseem ceeb ntawm cov khoom
Threadless Installation:Tshem tawm ntawm -site bar kawg npaj, threading tshuab, thiab xaus- cov txheej txheem ntxhov siab.
Direct Steel Kev Koom Tes:Radial compression quab yuam lub tes tsho cov ntaub ntawv mus rau hauv lub rebar tav, ua tiav kev sib koom ua ke lub zog uas ntau tshaj tus niam txiv rebar yield peev.
Visual Verification:Kev tshuaj xyuas siv Go/No- Mus rau sab nraud txoj kab uas hla calipers los ntsuas qhov ntev nias tawm tsam tshwj xeeb kam rau ua.
Tag nrho -Weather Application:Tsis muaj kev cuam tshuam los ntawm nag, qhov kub thiab txias, lossis qhov chaw kaw qhov chaw uas muaj kev txwv tsis pub siv vuam.
Compact Profile:Txo lub tes tsho sab nraud txoj kab uas hla tso cai rau kev tso kawm zoo nyob rau hauv congested rebar tawb thiab nruj structural clearance zones.

Qib & Standards
ISO 15835:Ua raws li cov khoom sib txuas sib txuas rau cov khoom zoo li qub thiab seismic.
SIB 318:Ua tau raws li Hom 2 cov qauv kev sib txuas uas yuav tsum tau ua (ntau tshaj 125% ntawm cov ntaub ntawv pov thawj rebar yield zog).
GB/T 1499.2 & JGJ 107:Qib II thiab Qib III cov txheej txheem kev ua tau zoo ntawm kev sib txuas.
ASTM A1034 Txuj:Kuaj rau tensile lub zog, elongation, thiab plam tsis kam nyob rau hauv cyclic loading.
Daim ntawv thov
Kev tsim kho choj:Txuas lub ntsiab qhov cuab lub zog nyob rau hauv choj piers, kab, thiab cap beams.
Tunnel Linings:Circumferential rebar sib txuas hauv cov ntaub thaiv npog tunneling thiab underground infrastructure.
Nuclear & Heavy Facilities:Siab -kev ncaj ncees cov pob qij txha yuav tsum nruj seismic tsis kam thiab qaug zog stability.
