Ib tug raug los ntawm Bolt Hook Anchor muaj ib tug threaded bolt los yog nuv bolt, ib tug expansion tes tsho, thiab ib tug wedge los yog expansion los ua ke. Nyob ntawm qhov tsim tshwj xeeb, cov tshuab ntxhua khaub ncaws thiab cov txiv ntoo kuj tseem yog ib feem ntawm kev sib dhos ua tiav.
Thaum lub fastener yog nruj, axial txheeb ze txav tshwm sim ntawm lub bolt thiab expansion sib dhos, ua rau lub tes tsho expansion nthuav tawm sab nraud thiab nias rau ntawm phab ntsa ntawm lub qhov drilled. Lub resulting radial siab tsim ib tug mechanical interlock thiab frictional tuav ntawm lub expansion los ua ke thiab lub hauv paus khoom.
Txoj kev thauj khoom thauj tuaj yeem yooj yim raws li hauv qab no:
Sab nraud load → Hook / Bolt → Threaded kev twb kev txuas → Expansion los ua ke → Base khoom
Yog li ntawd, txhua qhov kev sib txuas ntawm txoj kev thauj khoom yuav tsum tau saib xyuas. Txawm hais tias tus ntsia liaj qhov rooj nws tus kheej yog ua los ntawm siab - lub zog stainless hlau, cov teeb meem xws li tsis txaus embedment qhov tob, oversized laum qhov, pob zeb tawg, tsis txaus masonry zog, los yog tsis tiav expansion yuav tsis tau them rau tsuas yog los ntawm kev nce lub zog ntawm cov khoom siv ntsia liaj qhov rooj.
Khoom Specifications thiab Classification Matrix ntawm Hook Sleeve Bolt
Kev xaiv cov khoom siv ncaj qha hais txog kev ua haujlwm lifespan thiab ib puag ncig corrosion tsis kam ntawm fastener. Standard industrial daim ntaub ntawv thov kom nruj alloy ua raws.
| Fastener Classification | Cov Khoom Siv Tseem Ceeb | Mechanical & Corrosion Performance | Daim ntawv thov kev lag luam |
|---|---|---|---|
| Standard Qib | Carbon Steel (Q235 / C1015) nrog Zinc Plating (Ntau dua lossis sib npaug ntawm 8μm) | Tensile Strength Ntau dua los yog sib npaug rau 400MPa, Yield Strength Ntau dua los yog sib npaug rau 240MPa | Sab hauv HVAC ncua kev kawm ntawv, qhuav -ib puag ncig cable tais mounts |
| Corrosion-Resistant Qib | Austenitic Stainless hlau (AISI 304 / A2-70) | Pitting Resistance Equivalent Number (PREN) Ntau dua los yog sib npaug rau 18, siab oxidation kuj | Cov chaw kho dej, kev teeb tsa hauv ntug dej hiav txwv |
| Siab - Qib Kev Ua Haujlwm | Austenitic Stainless hlau (AISI 316 / A4-80) | Txhim kho molybdenum cov ntsiab lus, superior chloride thiab acid kuj | Marine ib puag ncig, tshuaj ua cov nroj tsuag, siab -cov av noo |
Configurations sib txawv los ntawm lub taub hau geometry kom haum raws li cov kev taw qhia load vectors, xws li nthuav lub tes tsho Anchor Hook, kaw -voj rings, thiab hnyav-duty forged load hooks.
Technical Installation Parameters thiab raws tu qauv ntawm lub tes tsho Expansion Hook Fastener
Kev ua tiav qhov ntsuas qhov kawg ntawm lub peev xwm yog nyob ntawm kev ua raws li qhov ua ntej -drilling thiab torque specifications tswj los ntawm cov txheej txheem txheej txheem fastening.
- Drill Hole Diameter Qhov tseeb:Qhov txoj kab uas hla yuav tsum nruj me ntsis raws li qhov nominal Concrete Phab ntsa Expansion Hook Anchor loj (siab ntev +0.15mm / -}0.10 mm) siv carbide-tipped laum khoom ua raws li ANSI B212.15 / ISO 5468 tus qauv. Cov qhov loj loj txo cov kev sib txhuam tuav txog li 40%.
- Kev npaj substrate:Compressed cua flushing thiab nylon txhuam clearing yuav tsum tshem tawm tag nrho cov pob zeb ua pob zeb thiab cov khib nyiab los ntawm lub hauv paus cov ntaub ntawv lub qhov ua ntej nkag.
- Daim ntawv thov Torque:Calibrated torque wrenches yuav tsum tau siv kom ncav cuag qhov pom zoo kom nruj torque qhov tseem ceeb. Hauv qab -torquing tiv thaiv lub tes tsho nthuav dav; tshaj -torquing txaus ntshai xov stripping los yog bolt shear tsis ua hauj lwm.
- Embedment Qhov tob: Minimum effective embedment depth (>50 mm rau tus qauv M8 / M10 variants) yuav tsum tau khaws cia hauv qab lub pob zeb nto, hla tsis yog - cov txheej txheem plaster lossis screed txheej.

Kev Saib Xyuas, Kev Tshawb Fawb, thiab Kev Tswj Xyuas Lub Neej Ntawm Kev nthuav dav phab ntsa Hook Bolt
Cov niaj hnub uas tsis yog- kev tshuaj xyuas kev puas tsuaj ua kom muaj kev nyab xeeb ntawm cov txheej txheem thiab kev ua haujlwm txuas ntxiv mus rau lub sijhawm ntev - kev xa tawm kev lag luam.
- Visual Surface Audit:Tshawb xyuas cov hlua khi thiab cov xov xov ib nrab-ib xyoos ib zaug rau cov pov thawj ntawm kev ntxhov siab tawg, hauv zos pitting, lossis txheej txheej degradation.
- Torque Verification Checks:Siv dynamic torque testing nyob rau hauv random sampling hauv paus (tsawg kawg 10% ntawm tag nrho cov ntsia pej xeem nyob rau hauv ib cheeb tsam) kom paub meej tias tuav ntawm clamping quab yuam.
- Kev Kho Kom Zoo Tam Sim No:Hloov ib qho Expansion Sleeve Anchor Hook nthuav tawm xov deformation, phab ntsa pob zeb spalling, los yog seem poob ntau tshaj 10% ntawm nominal txoj kab uas hla tam sim ntawd siv oversized hloov anchors los yog tsiv chaw drilling.
