Hnyav- lub luag haujlwm ua pob zeb thauj tog rau nkoj yog cov txheej txheem fastening thiab cov khoom sib txuas ua haujlwm rau kev tsim ua vaj tse precast, civil infrastructure, thiab cov tsev lag luam. Tsim los hloov siab tensile thiab shear loads ntawm precast ntsiab los yog structural steel ncej, cov thauj tog rau nkoj tshem tawm qhov yuav tsum tau rau qeeb, huab cua - nyob ntawm - qhov chaw ntub kev sib txuas thiab nruam welding. Lawv ua haujlwm tseem ceeb hauv kev thauj khoom-cov kabmob ntawm phab ntsa- mus rau- kev sib txuas hauv pem teb, kem- mus rau- cov kab sib txuas, thiab cov khoom siv hnyav.
Cov yam ntxwv tseem ceeb ntawm cov khoom
High Load Transfer Efficiency:Engineered los nqus cov ntsug shear sib xyaw ua ke, kab rov tav nro, thiab tawm - ntawm - dav hlau cua lossis seismic quab yuam yam tsis muaj kev cuam tshuam.
Precision Dimensional Control:Cov Cheebtsam yog tsim los siv automated CNC fiber ntau laser txiav thiab robotic vuam, tswj qhov tseem ceeb kev twb kev txuas pitch tolerances nyob rau hauv +/- 0.5 hli.
Traceable Material Integrity:Fabricated nruj me ntsis los ntawm cov ntawv pov thawj cov qauv steel qib thiab siab - lub zog fasteners mapped ncaj qha rau raw cov ntaub ntawv kub.
Site Installation Ceev:Ua ntej-engineered nrog slotted qhov thiab txheem xov configurations kom txo tau lub sij hawm tuav crane thiab ntawm - chaw ua hauj lwm los ua ke.

Load & Design Considerations
Static vs. Dynamic Loading:Txheeb xyuas seb daim ntawv thov puas muaj qhov tsis tu ncua ntawm cov khoom seem tuag, cua uplift, lossis cyclic fatigue loads los ntawm cov tshuab hnyav.
Qhob Strength Class:Cov khoom siv hauv paus pob zeb yuav tsum ua kom tau raws li qhov yuav tsum tau muaj zog compressive yam tsawg kawg nkaus (feem ntau C25/30 txog C50/60) txhawm rau tiv thaiv ntug kev tawg lossis lub khob tsis ua haujlwm nyob rau hauv qhov siab tshaj plaws thauj tog rau nkoj.
Ntug Distances & Spacing:Xyuas kom qhov tsawg kawg nkaus embedment qhov tob thiab qhov sib nrug ntawm qhov sib txawv ua raws li cov qauv kev suav software (xws li ACI lossis Eurocode tsim qauv) kom tsis txhob muaj qhov sib tshooj ntawm kev ntxhov siab.
Corrosion Ib puag ncig:Xaiv cov txheej tiv thaiv raws li ISO 12944 atmospheric classifications (piv txwv li, C3 rau cov chaw hauv nroog, C5 rau marine ib puag ncig).
Daim ntawv thov
Phab ntsa Precast- mus rau - Kev sib txuas hauv pem teb:Kev ruaj ntseg precast sab nrauv phab ntsa panels thiab sab hauv shear phab ntsa rau kab rov tav pem teb slabs thiab foundation podiums.
