Yuav Ua Li Cas Xaiv Txoj Cai Anchor Bolt rau Kev Ua Haujlwm Zoo

Anchor Bolt Fundamentalscov

Thauj tog rau nkoj bolts hloov loads los ntawm ib tug qauv mus rau nws lub hauv paus pob zeb, tiv thaiv rub-tawm, shear, thiab vibration rog. Tsis zoo li tus qauv bolts, lawv tau tsim los rau kev sib txuas nrog pob zeb los ntawm kev tuav, kev sib txhuam, lossis kev ua nplaum.

covCov ntawv thov tseem ceeb:

1. Steel ncej kev sib txuas
2. Heavy machinery mounting
3. Choj thiab kem baseplates
4. Lub tsev fencing thiab lub teeb ncej

Anchor Bolt Hom thiab Kev Ua Haujlwm Zoo

cov

cov1. Cast-in-Place Anchorscov

• covKev teeb tsa: Embedded thaum lub pob zeb pouring.
• covLub zog: Muaj peev xwm thauj khoom siab tshaj plaws (txog 50 kN tensile zog).
• covQhov zoo tshaj plaws rau: Cov txheej txheem tseem ceeb hauv cov txuas hniav los yog qhov siab.

cov2. Expansion Anchors (piv txwv li, Wedge Anchors).cov

• covMechanism: Expands tiv thaiv lub qhov phab ntsa thaum nruj.
• covLoad Capacity: 20-35 kN hauv cov pob zeb.
• covCov kev txwv: Zam nyob rau hauv tawg los yog hollow substrates.

cov3. Lub tes tsho Anchorscov

• covNtau yam: Haum rau pob zeb, cib, thiab thaiv.
• covMedium-Lub luag hauj lwm: Zoo tagnrho rau tes tuav, HVAC units (10–25 kN).

cov4. Los ntawm Boltscov

• covTsim: Hla tag nrho cov substrate; xav tau txiv ntseej / ntxhua khaub ncaws.
• covSiv Case: Steel beam-to-concrete kev sib txuas yuav tsum tau nquag disassembly.

cov5. Adhesive Anchorscov

• covKev sib khi: Epoxy lossis chemical resins sau qhov drilled.
• covQhov zoo: Tsis muaj zog expansion, zoo tagnrho rau ntug nrug

5-kauj ruam xaiv txheej txheemcov

1.Txhais Load Requirementscov

• Static loads (eg, signage): Qib 4.8–5.8 anchors.
• Dynamic/seismic loads: Qib 8.8+ nrog epoxy lossis expansion mechanisms.

2.Txheeb xyuas cov xwm txheej substratecov

• Khoom pob zeb: Expansion los yog wedge anchors.
• Hollow block / cib: Adhesive lossis lub tes tsho anchors.

3.Txiav txim siab Corrosion Resistance xav taucov

• Sab hauv / qhuav: Zinc-plated (ISO 4042).
• Ntug hiav txwv / tshuaj lom neeg: Stainless hlau A4 (ISO 3506).

4.xam Edge thiab Spacing txwvcov

• Yam tsawg kawg nkaus nrug = 5x thauj tog rau nkoj txoj kab uas hla.
• Qhov sib nrug ntawm cov thauj tog rau nkoj ≥10x txoj kab uas hla.

5.Txheeb xyuas qhov ua tau yooj yim installationcov

• Cast-in-place: Yuav tsum tau npaj cov formwork meej.
• Tom qab kev teeb tsa: Xav tau cov cuab yeej drilling thiab lub sijhawm kho (ntau hom nplaum).

Common Errors and Mitigationcov

covyuam kev 1: Siv wedge anchors hauv cov pob zeb tawg.
covKev daws teeb meem: Hloov mus rau adhesive anchors lossis helical bolts.

covyuam kev 2: Tshaj-tightening expansion anchors.
covQhov tshwm sim: Pob zeb spalling; torque rau 75% ntawm cov chaw tsim khoom txwv.

covyuam kev 3: Tsis quav ntsej thermal expansion.
covKho: Cia 2-3mm qhov sib txawv ntawm lub tes tsho anchors rau qhov kub thiab txias.

Cov lus pom zoo kawgcov

1. Rau cov txheej txheem siab-load ruaj khov, ua qhov tseem ceeb hauv qhov chaw los yog epoxy anchors.
2. Hauv kev teeb tsa corrosive, qhia meej stainless hlau A4 nrog 2 hli yam tsawg kawg nkaus txheej.
3. Ua pov thawj cov kev xaiv thauj tog rau nkoj los ntawm kev sim rub tawm (ICC-ES AC193 ua raws).
