Ngomnye weyona mibuzo ixhaphakileyo kwi-DIY kunye nokwenziwa lula - kwaye impendulo enyanisekileyo yile: kuxhomekeke. Isikrufu sokuzicofa kwishiti elicekethekileyo lesinyithi sinokubamba i-50-150 lbs, ngelixa isikrufu sobukhulu obufanayo esiqhutywa kumthi oqinileyo sinokubamba amakhulu aliqela eeponti. Akukho nombolo enye, kuba amandla okubamba isikrufu agqitywe ubuncinane ngezinto eziguquguqukayo ezintandathu ezisebenza kunye.
Loo nto ayithethi ukuba kufuneka uqashele. Esi sikhokelo sichaza ukuba yintoni egqiba ukuba bungakanani ubunzima anokububamba umntu ozicocayo, sinika amaxabiso ereferensi ayinyaniso kwiimeko eziqhelekileyo, kwaye sikubonisa indlela yokufumana ukusebenza okuphezulu kuso sonke isikrufu.
Impendulo emfutshane
Kwimihla ngemihla, usetyenziso olungezolwakhiwo, nalu uluhlu lwereferensi eqhelekileyo:
- Kwishiti elicekethekileyo (igeyiji eyi-18–22): i #10 self-tapping screw ngokuqhelekileyo ibamba 80–150 lbs ekuchebeni, ngamaxabiso asezantsi okutsalwa okuthe ngqo.
- Kumthi othambileyo (umzekelo, amaplanga e-SPF): i#8–#10 isikrufu esine-1.5–2 intshi yokudityaniswa komsonto ngokuqhelekileyo ibamba 100-250 lbs ekurhoxisweni.
- Kwi-hardwood: isikrufu esifanayo singabamba 200–500+ lbs, ngenxa yokuba amandla okurhoxisa aphakama ngokuxinana kweenkuni.
- Kwikhonkrithi okanye kwimasonry: i-self-tappers ayisiso isibophelelo esifanelekileyo - sebenzisa iiankile ezilinganiselwe kwi-substrate endaweni yoko.
La ngamaxabiso ereferensi yelizwe lokwenyani, hayi uhlengahlengiso loyilo. Kuyo nayiphi na into eyakhiwe, ukhuseleko-olubalulekileyo, okanye ngaphezulu, sebenzisa iitheyibhile zokuyila ezipapashiweyo kunye nokhuseleko olufanelekileyo - ngaphezulu koko kungezantsi.
Yintoni i-Self-Tapping Screw?
A self-tapping screw (idla ngokubizwa ngokuba yi-self-tapper) isika okanye yenze eyayo intambo njengoko iqhutywa kwi-material, ngoko ke akukho mngxuma ucofa ngaphambili ofunekayo. Kukho iintsapho ezimbini eziphambili:
- Ii-self-tappers ezenza imisonto - susa imathiriyeli ukwenza imisonto. Eyona nto ingcono kwimathiriyeli ethambileyo njengeplastiki, ialuminiyam, kunye neshiti lentsimbi.
- Ii-self-tappers zokusika imisonto - ube nemiphetho yokusika esusa izinto, uvelise intambo ecocekileyo kwizinto ezilukhuni njengentsimbi.
- I-self-drilling (TEK) izikrufu - icandelo lesithathu elinendawo yokudibanisa edibeneyo eyenza umngxuma wayo wokulingwa kwisinyithi, ukuphelisa inyathelo elihlukeneyo lokugaya.
Zonke ezi zabelana ngefiziksi efanayo: amandla okubamba avela kwimisonto elumayo kwizinto ezisisiseko, hayi kumzimba wesikrufu ngokwawo. Yiyo loo nto "ungakanani ubunzima onokuthi ubambe i-self-tapper?" ngokwenene umbuzo malunga ngokubambisana — Screw, imathiriyeli, kunye nofakelo zidityanisiwe.
Yintoni emisela ukuba Bungakanani ubunzima anokubuthwala umntu ozibethayo?
Zintandathu izinto ezilawulayo:
1. Screw diameter (igeyiji)
I-diameter enkulu = indawo yokudibanisa intambo = amandla angaphezulu okubamba. I #12 isikrufu siyakuhlala siphumeza i #8 yobude obufanayo kunye nemathiriyeli.
2. Ubude bothethathethwano lomsonto
Le yeyona nto ibalulekileyo. Ukubamba amandla anyuka ngokulinganayo ngokulingana nobude bentambo engcwatywe kwizinto ezifunyenweyo. Emithini, amandla okurhoxisa ngokuqhelekileyo alinganiswa nge-intshi nganye yokungena kwentambo - ukuphinda kabini ukungena ngokuphindwe kabini umthwalo onokuthi uthathwe, ukuya kwindawo apho i-screw shank ngokwayo iba likhonkco elibuthathaka.
3. Izinto ezisisiseko kunye nobuninzi bayo
- Ukhuni: amandla okurhoxisa ayenyuka ngoxinaniso - ngokurhabaxa ngokomlinganiselo womxhuzulane othile ophindwe kabini. I-screw kwi-oki emhlophe (SG ≈ 0.65) ibamba amaxesha amaninzi ngaphezu kwe-screw efanayo kwi-pine lightweight (SG ≈ 0.35).
- Intsimbi: ukukhupha kuxhomekeke kakhulu kubukhulu beshiti. Intsimbi etyebileyo inika imisonto ngakumbi ukuba ilume kuyo.
- Iplastiki: iiplastiki ezithambileyo zinika amandla okubamba asezantsi kakhulu kwaye zithande ukuhluba imisonto.
4. Izinto zokukrazula kunye nebakala
Uninzi lwabazicocayo luqina intsimbi yekhabhoni okanye isinyithi esingenasici. Amandla okuqina kwesikrufu abalulekile kuphela xa imisonto iyekile ukuba likhonkco elibuthathaka - oko kukuthi, kwiisubstrates ezixinene kakhulu ngokuzibandakanya okunzulu.
5. Umngxuma wokulinga
Umngxuma wokulinga ubungakanani obuchanekileyo uvumela imisonto ukuba isikwe ngokucocekileyo nangokupheleleyo. Umngxuma omncinci kakhulu ubangela ukuba i-screw ilwe nezinto (kwaye iyakwazi ukukrazula i-screw okanye ukhuni oluqhekezayo); umngxuma omkhulu kakhulu ushiya imisonto kungekho nto inokuyibamba.
6. Isalathiso somthwalo
I-Fasteners yomelele ngakumbi cheba (umthwalo ufakwe ngapha kwesikrufu) kunokungena ukutsalela ngaphandle (umthwalo utsala isikrufu ngqo ngaphandle kwesixhobo). Ilungu elingaphumeleliyo kuvavanyo lokutsalwa linokuthi libambe ubunzima obuninzi xa lilayishwe ecaleni.
Ukutsalwa ngaphandle vs. Shear: Iindlela ezimbini isikruru asiphumeleli
Ukuqonda iindlela ezimbini zokusilela kukuxelela ukuba yeyiphi inombolo omawukhathazeke ngayo:
| Layisha ulwalathiso | Imo Yokusilela | Amandla anxulumeneyo aqhelekileyo |
|---|---|---|
| Ukutsala ngqo ngaphandle | Imicu yokutsalwa kwemisonto / ukukhupha | Ngaphantsi - indawo ebuthathaka yizinto eziphathekayo |
| Layisha ngapha kwesikrufu | Ukusilela kokucheba | Ngaphezulu - i-screw shank kufuneka yophuke |
Kwishiti elicekethekileyo lesinyithi, ukungaphumeleli okuqhelekileyo kukutsalwa ngaphandle (imisonto ihluba umngxuma) okanye itsale (intloko ikrazula kwiphepha). Emthini, ukuxhathisa ukurhoxiswa yinto ethintelayo, kwaye iifomyula zeshishini zibonisa ukuba: i-NDS yoyilo lwe-equation yokurhoxiswa kweenkuni-screw is W = 2850 × G² × D (I-lbs nge-intshi nganye yokungena, apho i-G ingumxhuzulane okhethekileyo womthi kunye no-D yi-screw's idiameter yangaphandle ye-intshi). I-USDA Forest Products Laboratory's final-load version is F = 15700 × G² × D × L.
Ukubeka oko ngokwemigaqo esebenzayo: a #10 screw (D ≈ 0.19") eqhutywa 2 intshi zibe SPF ngamaplanga (G ≈ 0.42) has a ekugqibeleni ukuchasa ukurhoxiswa ebumelwaneni 400 lbs - ngelixa isikrufu efanayo kwi-oki emhlophe (G ≈ 0.65) ngaphezu kabini ukuba.
IReferensi yoMlayisho oqikelelweyo
| Isicelo | Isikere | Umthwalo oqhelekileyo ngeScrew | Amanqaku |
|---|---|---|---|
| Ishiti yentsimbi 18-22 gauge | #10 ukuzicofa ngokwakho | 80–150 lbs (chear) | Tsala-ngaphandle ezantsi; sebenzisa indawo yokuzibambela |
| Isakhelo sentsimbi elula (12–16 ga) | #8–#12 ukuzicofa ngokwakho | 150–300+ lbs | Qinisekisa ngokuchasene neetafile zoqhagamshelwano ezipapashiweyo |
| I-Softwood, i-1.5-2" uthethathethwano | #8–#10 | 100–250 lbs (ukurhoxiswa) | Inyuka ngobunzulu kunye nokuxinana |
| Umthi onzima, 1.5-2 "ukuzibandakanya | #8–#10 | 200–500+ lbs (ukurhoxa) | Iintlobo ezixineneyo zibamba kakhulu |
| Intsimbi ukuya kwintsimbi, igeyiji enzima | 1/4" ukuzibetha ngokwakho | 1,000+ lbs kunokwenzeka (cheba) | Izakhiwo ezidibeneyo zifuna ixabiso loyilo |
Zithathe ezi njengezalathisi eziyinyaniso kumgangatho wevenkile. Ubuchule boyilo obupapashiweyo bokubumba isinyithi (ngokwe-AISI S100 / ICC-ES iingxelo zovavanyo) ngokuqhelekileyo zisebenzisa ukhuseleko olumalunga ne-3.0 kumaxabiso avavanyiweyo okugqibela - okuthetha ukuba kuvumelekile umthwalo ungaphantsi kakhulu koko isiqhoboshi sisinda kuvavanyo lwaselabhu. Xa umthwalo ubalulekile, sebenzisa iitafile zoyilo, hayi amanani okugqibela.
Uyenza njani kakhulu into enokuthi ibanjwe ngumntu ozibethayo
- Sebenzisa elona dayamitha inkulu ebonakalayo. Xa uthandabuza phakathi kobukhulu obubini, nyusa.
- Yandisa unxibelelwano lomsonto. I-screw kufuneka ingene kwisixhobo esifumanayo ngobude obaneleyo obunemisonto - kuqhagamshelo lwentsimbi, inqaku kufuneka liphume kwaye libandakanye ubuncinci imisonto emibini okanye emithathu ngaphaya kwecala elikude.
- Gqoka umngxuma wokulinga ofanelekileyo. Ngokhuni, umngxuma wokuqhuba uthintela ukwahlula; ngentsimbi, sebenzisa isikrufu somngxunya esicetyiswayo somngxuma ukuze umsonto ulume ngokuchanekileyo.
- Khetha uhlobo olufanelekileyo lwezinto eziphathekayo. Ukusika intambo yentsimbi, ukwenza intambo kwizinto ezithambileyo, ukuzibambela ngamanqaku e-TEK xa ufuna ukutsiba inyathelo lokulinga.
- Musa ukuqinisa ngokugqithisileyo. Ukukrazula umngxuma kutshabalalisa uninzi lwamandla okubamba. Yima xa izihlalo zentloko ziqinile.
- Sebenzisa iiwasha kwizinto ezibhityileyo. Iwasha yolula umthwalo wentloko kwaye ithintele ukutsalwa kwentsimbi ethambileyo.
- Yongeza ezinye iziqhoboshi. Ukubeka izikrufu ezininzi kwijoyini kwandisa umthamo - kwaye kubonelela ngokuphinda-phinda ukuba isikrufu esinye sibuthathaka kunoko bekulindelekile.
Xa i-Self-Tapper ayiyompendulo echanekileyo
Abazicofayo banemida. Ungawasebenziseli:
- Imidibaniso yolwakhiwo okanye yobunjineli - izakhiwo zophahla, iifreyimu ezithwala imithwalo, okanye nantoni na elawulwa yikhowudi yokwakha. Sebenzisa izikrufu ezireyithiweyo zesakhiwo, iibholithi, okanye iziqhoboshi zobunjineli ezinamaxabiso oyilo apapashiweyo.
- Izicelo ezingaphezulu okanye ezibaluleke ngokhuseleko - ungaze uxhome abantu, izixhobo ezinzima, okanye nantoni na enokwenzakalisa umntu kwisikrufu esinye esingalinganiselwanga.
- Iindawo zokungcangcazela okuphezulu - imisonto inokubuyela umva ngokuhamba kwexesha; qwalasela iikhompawundi zokutshixa intambo okanye iziqhoboshi zokutshixa ngoomatshini.
- Ikhonkrithi okanye ilitye — abazicocayo abananto yokuluma; sebenzisa i-ankile zokwandisa, iiankile zemikhono, okanye i-ankile ze-wedge ezilinganiselwe kwi-substrate.
Umgaqo ulula: ukuba ukungaphumeleli kuya kwenzakalisa umntu okanye kubize imali eninzi, ubukhulu be-fastener ukusuka kwidatha yoyilo epapashiweyo kwaye usebenzise ukhuseleko olufanelekileyo - kwaye xa ungathandabuzeki, cela injineli.
