Expansion bolts feem ntau yog siv cov fasteners dav siv hauv kev kho thiab teeb tsa cov tsev, cov cuab yeej siv, thiab tshuab. Lawv txoj hauv kev ua haujlwm yuav tsum tau muab cov ntsia hlau ntsia rau hauv lub raj txuas ntxiv; kev koom tes ntawm lub ntsia liaj qhov rooj thiab lub expansion tube tsim ib tug muaj zog mechanical anchoring nyhuv, ruaj khov kho cov ntsia liaj qhov rooj rau ib tug substrate xws li pob zeb los yog cib phab ntsa. Thaum cov txiv ntseej yog nruj, cov khoom elastic nyob rau hauv lub expansion tube yog compressed thiab nthuav tawm sab nraud, nruj nreem tuav lub phab ntsa ntawm lub qhov nyob rau hauv lub substrate, generating muaj zog kev sib txhuam thiab shear rog, yog li securely txuas cov khoom ruaj khov rau lub substrate. Cov qauv ntawm Expansion Anchor feem ntau suav nrog cov khoom xws li lub tog raj kheej, lub raj xa dej, lub tshuab ntxhua khaub ncaws, thiab lub txiv ntoo hexagonal. Lub taub hau ntsia liaj qhov rooj yog recessed, yaug nrog lub substrate nto, kom muaj kev zoo nkauj pleasing installation; lub expansion raj feem ntau yog ua los ntawm hlau thiab muaj ib tug radially expandable caij nplooj ntoos hlav los yog conical tes tsho; lub tshuab ntxhua khaub ncaws ua rau thaj tsam kev ntxhov siab thiab tiv thaiv kev puas tsuaj rau lub substrate nto; thiab cov txiv ntoo hexagonal muab lub zog nruj. Nyob ntawm daim ntawv thov tshwj xeeb, Kev nthuav dav Anchors tuaj yeem ua los ntawm cov hlau xws li carbon steel, alloy steel, lossis stainless hlau, nrog rau cov ntaub ntawv sib xyaw xws li iav fiber reinforced plastics, kom ua tau raws li qhov yuav tsum tau ua ntawm qhov chaw ua haujlwm sib txawv, xws li kub, tsis tshua muaj kub, av noo, thiab corrosive tej yam kev mob. Piv txwv li, nyob rau hauv ib puag ncig sab nraum zoov, galvanized carbon steel Phab ntsa Anchors tuaj yeem tiv thaiv xeb, thaum nyob rau hauv ib puag ncig corrosive heev xws li cov nroj tsuag tshuaj, 316 stainless hlau yuav tsum tau ua kom ntseeg tau ntev -lub sij hawm.
Ntau yam yuav tsum tau xav txog thaum xaiv Phab Ntsa Anchors. Ua ntej, hom substrate yog ib qho tseem ceeb, xws li cov khoom siv phab ntsa (pob zeb, masonry, hollow cib, sib faib cov boards, thiab lwm yam). Lub hardness thiab porosity ntawm sib txawv substrates ho cuam tshuam rau expansion nyhuv. Tsis tas li ntawd, qhov txawv specifications ntawm Hollow Phab ntsa Anchors muaj qhov sib txawv load- bearing capacities; cov neeg siv yuav tsum xaiv qhov tsim nyog specification raws li qhov hnyav ntawm cov khoom raug kho. Piv txwv li, M6 Hollow Phab Ntsa Anchor tuaj yeem nqa tau kwv yees li 100 kg thiab tsim nyog rau kev kho cov khoom me me los yog cov khoom siv hnyav; thaum M12 ntsia liaj qhov rooj tuaj yeem nqa tau qhov hnyav dua, txog li 500 kg lossis ntau dua, thiab feem ntau yog siv rau kev txhim kho cov tshuab hnyav lossis cov khoom siv. Ib puag ncig tej yam kev mob kuj yog ib qho tseem ceeb rau kev xaiv thaum xaiv lawv, tshwj xeeb tshaj yog nyob rau hauv cov av noo (xws li chav dej thiab hauv qab daus), siab -cov av noo los yog los nag, los yog cov chaw uas muaj acidic los yog alkaline corrosive tshuaj (xws li chemical workshops thiab ntsev tsuag ib puag ncig ntawm ntug hiav txwv dej). Stainless hlau expansion bolts yuav tsum tau xaiv nyob rau hauv cov chaw no, raws li lawv nto yog passivated, muab zoo heev corrosion kuj thiab ncua lawv cov kev pab cuam lub neej. Rau cov tsev uas xav tau kev tiv thaiv hluav taws, Qhob Screws ntsib cov kev ntsuas hluav taws xob sib raug zoo yuav tsum raug xaiv kom ntseeg tau tias lawv tswj tau qee theem ntawm kev ruaj ntseg thaum muaj hluav taws kub.
Installation ntawm expansion bolts yog kuj yooj yim. Ua ntej, lub qhov yuav tsum tau drilled raws li lub bolt specifications, nrog rau lub qhov taub ntawm lub bolt lub sab nraud txoj kab uas hla. Feem ntau, lub qhov taub yog 1-2 hli loj dua lub taub hau taub hau kom paub meej txaus qhov chaw nthuav dav rau lub raj txuas. Piv txwv li, lub qhov taub drilled rau M8 Concrete Screw feem ntau yog 10 hli. Tom qab ntxuav cov plua plav thiab cov khib nyiab los ntawm lub qhov, txhuam los yog cov cua compressed tuaj yeem siv los tshuab tawm txhua qhov impurities, kom ntseeg tau tias lub raj xa dej tuaj yeem nkag tau yooj yim thiab nthuav dav. Ntxig lub pob zeb ntsia hlau rau hauv lub qhov, kom ntseeg tau tias lub raj txuas ntxiv tau muab tso rau tag nrho. Tom qab ntawd, nruj lub hex txiv ntoo nrog ib tug ciaj ntswj los yog ntswj ntsia hlau kom txog rau thaum koj hnov zoo li tsis pom kev. Lub sijhawm no, lub raj xa dej tau nthuav dav tag nrho thiab nyob rau hauv kev sib cuag nrog lub substrate, tsim kom muaj kev ruaj ntseg zoo. Thaum lub sij hawm installation, nws yog ib qho tseem ceeb los xyuas kom meej lub drilled qhov taub thiab qhov tob sib phim lub bolt specifications. Cov teeb meem xws li lub qhov taub tsis txaus (ua rau lub raj xa dej tsis tuaj yeem nthuav dav), lub qhov taub ntau dhau (ua rau lub zog tsis txaus), lossis tsis txaus drilling qhov tob (tiv thaiv lub ntsia liaj qhov rooj los ntawm tag nrho cov ntsia hlau) yuav cuam tshuam rau kev txhim kho thiab kev nyab xeeb ntawm cov qauv.
Hauv kev siv tswv yim, muaj ntau ntau hom Expansion Anchors, thiab hom tsim nyog tuaj yeem xaiv raws li qhov xav tau sib txawv. Piv txwv li, sab nrauv phab ntsa Anchors (tseem hu ua expansion tube bolts) feem ntau yog siv rau hauv tsev kho kom zoo nkauj (xws li cov phuam racks thiab racks), kev kho cov cuab yeej siv, thiab kev sib txuas ntawm lub tsev dav dav vim lawv qhov yooj yim ntawm kev teeb tsa thiab tus nqi qis. Internal Masonry Bolts (tseem hu ua expansion thauj tog rau nkoj bolts) yog tsim rau lub sijhawm uas zoo nkauj yog qhov tseem ceeb, xws li kho siv lead ua chandeliers, phab ntsa teeb, kev ruaj ntseg qhov rais, thiab blinds. Lawv qhov nthuav dav yog nyob rau hauv lub ntsia liaj qhov rooj, ua rau lub ntsej muag du tom qab kev teeb tsa thiab tsis cuam tshuam rau cov nyhuv zoo nkauj. Rau cov ntaub ntawv tshwj xeeb, Masonry Bolts tshwj xeeb tau qhia rau lub lag luam, xws li thauj tog rau nkoj bolts rau hollow cib phab ntsa (nrog rau lub qhov tshwj xeeb loj qhov tsim kom haum rau lub qhov qauv ntawm hollow cib), core-tsav Masonry Bolts (ntsuas los ntawm hammering, tsis muaj pre-drilling yuav tsum tau, ib ntus chob cov ntaub ntawv kho), haum rau bolts los yog ib tug tshwj xeeb bolts. tom qab kho los ntawm kev txhaj tshuaj nplaum, haum rau cov xwm txheej uas cov pob zeb muaj zog tsawg lossis kev puas tsuaj rau lub substrate tsis tso cai). Cov hom tshwj xeeb no txuas ntxiv nthuav dav daim ntawv thov ntau yam ntawm lawv.
Qib zog ntawmExpansion Boltsfeem ntau yog qhia los ntawm cov lej. Piv txwv li, "8.8 qib" qhia tias lub zog tensile ntawm 800 MPa thiab lub zog tawm ntawm 640 MPa. Cov qib siab dua, zoo li 10.9, muab lub zog ntau dua rau cov qauv tseem ceeb. Stainless hlau thauj tog rau nkoj yog cim nrog cov lej zoo li "A2-70," qhia tias austenitic stainless hlau nrog lub zog tensile yam tsawg kawg nkaus ntawm 700 MPa, haum rau corrosive ib puag ncig.
Raws li kev tsim kho kev lag luam hloov zuj zus, yog li cov thev naus laus zis tom qab cov fasteners no. Cov ntaub ntawv sib xyaw tshiab, xws li iav fiber reinforced nylon, tau txais cov koob npe vim lawv lub teeb yuag, corrosion tsis kam, thiab kev qaug zog zoo heev. Cov qauv tsim tshwj xeeb rau ntau hom phab ntsa thiab qhov tshwm sim ntawm cov cuab yeej tsim kho ntse kuj tseem txhim kho kev txhim kho kev ua haujlwm thiab raug. Kev txhim kho yav tom ntej yuav tsom mus rau ib puag ncig sustainability, txhim kho kev ua tau zoo, thiab kev ua haujlwm ntau yam kom tau raws li cov kev xav tau sib txawv ntawm ntau qhov kev lag luam.
