Anchor bolts yog cov fasteners muaj zog uas tau kho nyob rau hauv cov khoom siv thauj khoom thiab tuav cov qauv. Lawv tau txais lawv lub npe los ntawm lo lus German "anker", uas txhais tau tias "txheej txheem". Lub npe no tsis yog qhov xwm txheej, vim nws nyuaj rau nrhiav tau lwm cov fasteners uas tsis qis dua rau cov bolts ntawm lub zog thiab kev ntseeg siab. Yuav ua li cas nkag siab txhua yam ntawm cov khoom hlau no?
Anchor bolts tuaj yeem muab faib ua 2 pawg loj: lub hauv paus bolts thiab Molly bolts. Thawj suav nrog fasteners nyob rau hauv daim ntawv ntawm ib tug pas nrig nrog ib tug xov thov mus rau ib tug kawg thiab ib tug tshwj xeeb ntaus ntawv uas tuav nws nyob rau hauv lub hauv paus. Cov thauj tog rau nkoj bolts no yog tsim los kho cov khoom siv thiab ntau yam qauv. Lawv yog siv nyob rau hauv tej kev tsim kho (tsev, vaj tse, dams, fais fab nroj tsuag, txuas hniav, thiab lwm yam). Foundation bolts lav ruaj ntseg fastening rau lub hauv paus muaj zog thiab tsis-elastic. Lawv muaj ib qho cim ntawm qhov kawg ntawm cov studs nrog lub nominal txoj kab uas hla ntawm thauj tog rau nkoj xov thiab qhov ntev ntawm stud (hauv cm). Ntawm cov studs ntawm bolts npaj rau kev ua haujlwm ntawm qhov kub qis dua -40 ° C, lawv kuj muab cov npe"HL"
Molly Anchor Bolts yog tsim los siv rau hauv cov qauv hollow uas muaj peev xwm tsawg. Lawv yog siv thaum ua hauj lwm nrog drywall, fiberboard, gypsum fiber los xij, hollow cib thiab hollow blocks. Cov bolts no tau nruab nrog tshwj xeeb "collet" uas qhib thaum lub ntsia liaj qhov rooj tau nruj. Nws nruj nreem so ntawm lub hauv paus ntawm nws sab hauv. Nyob rau sab nrauv ntawm lub collet muaj ib tug pheej "skirt" nrog spikes uas ploj mus thaum nruj rau hauv lub hauv paus khoom. Cov cuab yeej no tiv thaiv lub collet los ntawm tig. Rau qee hom Molly bolts, lub collet yog muab cais los ntawm lub fastener no.
Nyob ntawm daim ntawv thov, anchors tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg. Lawv yog siv rau fastening qhov rooj thaiv, mounting teeb pom kev zoo fixtures, qhov rais thav duab, cuav ceilings, thiab lwm yam. Cov fasteners no yog tsim los ntawm niaj hnub technologies los ntawm cov ntaub ntawv zoo. Cov neeg uas nyob deb ntawm kev tsim kho tsis paub yuav kho cov thauj tog rau nkoj bolts. Thiab qhov no yog ua tau yooj yim heev: lawv yog hammered rau hauv lub qhov npaj, thiab ces nruj nreem kaw nrog ib tug wrench. Nyob rau hauv tus txheej txheem ntawm zawm cov ntsia hlau, lawv yog ruaj khov kho nyob rau hauv cov khoom. Lub thauj tog rau nkoj ntsia liaj qhov rooj yog ruaj khov nyob rau hauv lub hauv paus ua tsaug rau 3 txoj kev ua hauj lwm: kev sib txhuam, nres, gluing (embedding). Feem ntau cov fasteners tau tuav nyob rau hauv qhov chaw los ntawm kev sib xyaw ua ke ntawm tag nrho cov ntsiab cai no. Hlau thauj tog rau nkoj bolts tuaj yeem muaj txoj kab uas hla ntawm 12-100 mm, txawm hais tias nyob rau qee hom kev siv fasteners thiab loj dua.txoj kab uas hla. Cov fasteners no raug rhuav tshem hauv lawv qhov chaw tsis muaj zog. Lawv muaj cov yam ntxwv ntawm kev puas tsuaj hauv qab no: rhuav tawm ntawm lub hauv paus, tawg lossis khoov, shearing, tearing tawm nrog cov khoom siv hauv paus, melting, hlau corrosion.
HILTI fasteners yog ib qho ntawm cov khoom lag luam nrov tshaj plaws nyob rau hauv ntau yam ntawm thauj tog rau nkoj bolts. Lawv yog siv nyob rau hauv kev tsim kho thiab kho cov hauj lwm. Lub tuam txhab no tsim ntau hom fasteners, uas nrov tshaj plaws yog Hilti mechanical thiab tshuaj anchor bolts. Lawv txhim khu kev qha thiab muaj ib qho yooj yim mounting txoj kev. Qhov ntau ntawm cov khoom no tsuas yog loj, tab sis feem ntau ntawm cov khoom muaj feem xyuam rau cov thauj tog rau nkoj ntawm ntau yam duab thiab ntau thiab tsawg.
