Yog tias koj puas tau ntsia ntawm pawg fasteners xav paub yuav ua li cas npaj lawv, koj tsis nyob ib leeg. Ib lo lus nug uas peb tau txais yog: Kuv puas tuaj yeem khaws cov thauj tog rau nkoj nrog cov ntsia hlau tsis tu ncua, lossis lawv puas yuav ua rau ib leeg? Cov lus teb luv luv: Nws tsis pom zoo, tab sis nws nyob ntawm txoj kev khaws cia. Cia peb tawg vim li cas kev sib xyaw ua ke tuaj yeem ua rau muaj teeb meem thiab yuav ua li cas khaws cov bolts thiab cov bolts tsis tu ncua.
Vim li cas khaws Anchor Bolts nrog Nruam Bolts Risks puas
Thauj tog rau nkoj bolts (hnyav-lub luag hauj lwm fasteners siv los ruaj steel kem, khoom siv, los yog cov qauv rau pob zeb) thiab bolts tsis tu ncua (txhua hnub fasteners rau kev nruj nruj) yuav zoo ib yam, tab sis lawv qhov sib txawv ua rau sib xyaw cia pheej hmoo. Nov yog dab tsi tuaj yeem mus tsis ncaj ncees lawm:
Xov puas yog qhov txaus ntshai tshaj plaws
Thauj tog rau nkoj bolts feem ntau muaj tuab, sib sib zog nqus threads tsim los tuav pob zeb los yog masonry nruj nreem. Cov bolts tsis tu ncua - zoo li hex bolts lossis tshuab bolts - muaj cov xov zoo dua rau kev sib raug zoo, zoo nkauj. Thaum jostled ua ke nyob rau hauv ib tug bin:
Corrosion kis tau sai dua
Ntau lub thauj tog rau nkoj yog galvanized (zinc-coated) los tiv thaiv xeb, tshwj xeeb tshaj yog rau kev siv sab nraum zoov lossis damp pob zeb. Cov bolts tsis tu ncua tej zaum yuav yog hlau liab qab, pleev xim rau, lossis muaj cov txheej txheem sib txawv. Thaum khaws cia ua ke:
Tsis meej pem nkim sij hawm (thiab nyiaj txiag)
Anchor bolts tuaj nyob rau hauv qhov ntev (feem ntau 12+ ntiv tes) thiab cov duab (L-shaped, J-shaped, thiab lwm yam). Cov bolts tsis tu ncua yog luv thiab ncaj. Kev sib xyaw ua ke ua rau koj nkim sij hawm txheeb xyuas tom qab. Qhov phem tshaj, ua yuam kev ib lub bolt tsis tu ncua rau lub thauj tog rau nkoj ntsia liaj qhov rooj (los yog vice versa) ua rau kev sib txuas xoob thiab muaj peev xwm ua tsis tiav.
Thaum twg Lawv tuaj yeem khaws cia ua ke (ib ntus)?
Yog tias koj nyob hauv kev khi (xws li, qhov chaw cia tsawg), ua raws li cov cai no kom txo qis kev puas tsuaj thaum khaws cov thauj tog rau nkoj nrog cov ntsia hlau ib ntus:
- Sib cais los ntawm qhov loj me ua ntej: Khaws cov bolts me me kom deb ntawm cov thauj tog rau nkoj loj - qhov sib txawv loj dua txhais tau tias muaj kev sib tsoo ntau dua.
- Siv cov khoom faib lossis cov thawv ntim khoom:
- Tsis txhob hnyav-rau-lub teeb stacking: Tsis txhob cia hnyav thauj tog rau nkoj bolts so ntawm me me bolts - qhov no crushes threads los yog khoov shanks.
- Txheeb xyuas cov txheej txheem: Yog tias siv galvanized thauj tog rau nkoj bolts nrog liab qab steel tsis tu ncua bolts, ntxiv kev xav lossis yas ntawm lawv los tiv thaiv khawb.
Cov kev coj ua zoo tshaj plaws rau khaws cov thauj tog rau nkoj thiab cov bolts tsis tu ncua
Rau cov bolts tsis tu ncua, nws yog ib qho tseem ceeb kom lawv qhuav los ntawm kev khaws cia rau hauv qhov chaw tswj kev nyab xeeb; rau cov hlau tsis tu ncua bolts, nyias txheej ntawm lub tshuab roj tuaj yeem siv los tiv thaiv xeb (tsuas yog nco ntsoov so nws tawm ua ntej siv), thiab lawv yuav tsum muab khaws cia nrog lawv cov txiv ntseej thiab cov ntxhua khaub ncaws hauv tib qhov chaw kom nkag tau yooj yim. Raws li rau thauj tog rau nkoj bolts, yog tias dai tsis ua tau, lawv yuav tsum tau muab tso rau hauv qhuav, kaw cov hnab yas ntim nrog cov desiccants kom nqus dej noo, thiab hauv qab ntawm cov bins yuav tsum tau ua npuas ncauj los tiv thaiv cov xov; Tsis tas li ntawd, lawv yuav tsum tau sau kom meej meej nrog cov ntsiab lus xws li qhov ntev, txoj kab uas hla, thiab txheej txheej (xws li, "Galvanized L-shaped anchor bolt, 16 inches") kom tsis txhob muaj kev ntxhov siab.
Xaus
Anchor bolts yog "workhorses" rau hnyav, mus tas li loads; tsis tu ncua bolts tuav txhua hnub fastening. Kev kho lawv raws li kev hloov pauv tau thaum lub sijhawm khaws cia ua rau lawv qhov kev ua tau zoo. Siv sij hawm los khaws cia lawv cais tsis txhob raug nqi hloov pauv thiab, qhov tseem ceeb tshaj, kev ua haujlwm tsis zoo.
Los ntawm ua raws li cov kauj ruam no, koj yuav khaws cov bolts thiab cov bolts tsis tu ncua nyob rau hauv cov xwm txheej saum toj kawg nkaus, npaj txhij ua thaum koj xav tau.
