Ndi limodzi mwamafunso omwe amafunsidwa kwambiri mu DIY komanso kupanga kosavuta - ndipo yankho lowona mtima ndilakuti: zimatengera. Chomangira chodzikhomera chokha muchitsulo chopyapyala chimatha kukhala ndi ma 50-150 lbs, pomwe zomangira zamtundu womwewo zowomberedwa mumtengo wolimba zimatha kusunga mapaundi mazana angapo. Palibe nambala imodzi, chifukwa mphamvu yogwirizira ya screw imasankhidwa ndi masinthidwe osachepera asanu ndi limodzi omwe amagwira ntchito limodzi.
Izi sizikutanthauza kuti muyenera kungolingalira. Bukhuli likufotokoza zomwe zimatsimikizira kuchuluka kwa kulemera kwa munthu wodzimenya yekha, amapereka zenizeni zenizeni zomwe zimachitika nthawi zambiri, ndikukuwonetsani momwe mungapangire ntchito yabwino pa screw iliyonse.
Yankho Lachidule
Pazinthu zatsiku ndi tsiku, zomwe sizinapangidwe, nayi mitundu yofananira:
- Pazitsulo zopyapyala (18-22 gauge): # 10 self-tapping screw nthawi zambiri imakhala 80-150 lbs mu kukameta ubweya, yokhala ndi zotsika mtengo zokoka molunjika.
- Mu softwood (mwachitsanzo, matabwa a SPF): #8–#10 screw yokhala ndi mainchesi 1.5–2 a ulusi wolumikizana nthawi zambiri imakhala 100-250 lbs pakuchotsa.
- Mu hardwood: wononga yemweyo akhoza kugwira 200-500+ lbs, chifukwa mphamvu yochotsa imakwera ndi kachulukidwe ka nkhuni.
- Mu konkriti kapena miyala: zodzipangira tokha sizomwe zimamangirira bwino - gwiritsani ntchito anangula ovotera gawo lapansi m'malo mwake.
Izi ndi zenizeni zenizeni, osati makonzedwe apangidwe. Pachilichonse chokhazikika, chofunikira kwambiri pachitetezo, kapena chapamwamba, gwiritsani ntchito matebulo apangidwe osindikizidwa ndi chitetezo choyenera - zambiri pazomwe zili pansipa.
Kodi Self-Tapping Screw N'chiyani?
A kudzigunda wononga (nthawi zambiri amangotchedwa self-tapper) amadula kapena kupanga ulusi wake pamene akukankhidwira muzinthu, kotero kuti palibe dzenje lomwe likufunika. Pali mabanja awiri akulu:
- Odzipangira okha ulusi - kusuntha zinthuzo kupanga ulusi. Zabwino kwambiri pazinthu zofewa monga pulasitiki, aluminiyamu, ndi zitsulo zopyapyala.
- Odzicheka okha ulusi - kukhala ndi mbali zodula zomwe zimachotsa zinthu, kupanga ulusi woyeretsa muzinthu zolimba monga chitsulo.
- Zomangira zodzibowolera zokha (TEK). - gulu lachitatu lomwe lili ndi malo obowola ophatikizika omwe amabowola dzenje lake loyendetsa muzitsulo, ndikuchotsa njira yoboola yosiyana.
Zonsezi zimagawana fiziki yofanana: mphamvu yogwira imachokera ku ulusi womwe umaluma muzinthu zapansi, osati kuchokera ku screw body. Ndicho chifukwa chake "kolemera kotani komwe munthu wodziwombera yekha angagwire?" kwenikweni ndi funso la pamodzi - wononga, zinthu, ndi kukhazikitsa pamodzi.
Kodi Ndi Chiyani Chimatsimikizira Kuti Munthu Wodzitapa Angathe Kulemera Motani?
Zinthu zisanu ndi chimodzi zimalamulira:
1. Screw diameter (gauge)
Kukula kwakukulu = malo olumikizana ndi ulusi = mphamvu zambiri zogwira. Zowononga # 12 nthawi zonse zimakhala bwino kuposa #8 kutalika ndi zinthu zomwezo.
2. Kutalika kwa chinkhoswe
Ichi ndi chinthu chimodzi chofunikira kwambiri. Kugwira mphamvu kumawonjezeka molingana ndi kutalika kwa ulusi wokwiriridwa muzinthu zolandirira. Mu nkhuni, mphamvu yochotsa nthawi zambiri imavoteredwa pa inchi yolowera ulusi - kuwirikiza kawiri kulowetsako kuwirikiza kawiri katundu yemwe olowa angatenge, mpaka pomwe phula lolowera limakhala ulalo wofooka.
3. Zida zoyambira ndi kachulukidwe kake
- Wood: mphamvu yochotsa imakwera ndi kachulukidwe - pafupifupi molingana ndi mphamvu yokoka yeniyeni. Zowononga mu oak woyera (SG ≈ 0.65) zimagwira kangapo kuposa zowononga zomwezo mu pine wopepuka (SG ≈ 0.35).
- Chitsulo: kutulutsa kumadalira kwambiri makulidwe a pepala. Chitsulo chokhuthala chimapangitsa kuti ulusiwo ulumikizike.
- Cha pulasitiki: mapulasitiki ofewa amapereka mphamvu zotsika kwambiri ndipo amakonda kuvula ulusi.
4. Screw zinthu ndi kalasi
Ambiri odzipangira okha ndi chitsulo cholimba cha carbon kapena chitsulo chosapanga dzimbiri. Kulimba kwa wononga kwake kumangofunikira ulusiwo ukasiya kukhala ulalo wofooka - mwachitsanzo, m'malo owundana kwambiri ndikuchitapo kanthu mozama.
5. Bowo loyendetsa ndege
Bowo loyendetsa bwino lomwe limapangitsa kuti ulusi udulidwe bwino komanso mokwanira. Bowo laling'ono kwambiri limapangitsa kuti wononga kulimbana ndi zinthu (ndipo imatha kuthyola wononga kapena kugawa nkhuni); dzenje lalikulu kwambiri limasiya ulusi wopanda chilichonse chogwira.
6. Njira ya katundu
Zomangamanga ndizolimba kwambiri kukameta ubweya (katundu woyikidwa pa screw) kuposa in kukokera kunja (katundu kukoka wononga molunjika kuchokera ku zinthu). Mgwirizano womwe umalephera kuyesa kukoka ukhoza kukhala wolemera kwambiri ukapakidwa cham'mbali.
Pull-Out vs. Shear: Njira Ziwiri Zopangira Chingwe Zimalephera
Kumvetsetsa mitundu iwiri yolephera kumakuuzani nambala yomwe muyenera kuda nkhawa nayo:
| Katundu Mayendedwe | Kulephera Mode | Mphamvu Yachibale Yofananira |
|---|---|---|
| Kukoka molunjika kunja | Mizere mizere / kukokera kunja | M'munsi - chofooka mfundo ndi zakuthupi |
| Kwezani pa screw | Kukameta ubweya kulephera | Pamwamba - wononga shank ayenera kusweka |
Muzitsulo zopyapyala, kulephera kwanthawi zonse ndiko kukokera (ulusi kuvula dzenje) kapena kukokera (mutu ukung'amba pepala). Mu nkhuni, kukana kuchotsa ndizomwe zimalepheretsa, ndipo njira zamakampani zikuwonetsa kuti: NDS kapangidwe kake kakuchotsa nkhuni W = 2850 × G² × D (ma lbs pa inchi yolowera, pomwe G ndiye mphamvu yokoka ya nkhuni ndipo D ndi mainchesi a ulusi wakunja). Mtundu womaliza wa USDA Forest Products Laboratory ndi F = 15700 × G² × D × L.
Kuyika izi m'mawu othandiza: wononga #10 (D ≈ 0.19") yoyendetsedwa ndi mainchesi 2 kupita ku matabwa a SPF (G ≈ 0.42) ili ndi kukana komaliza kochotsa pafupi ndi 400 lbs - pomwe wononga chomwecho mu thundu woyera (G ≈ 0.65) kuwirikiza kawiri.
