Kuwona
. Chifukwa cha izi, choyamba, mfundo zaku Britain ndi America sizigwirizana ndi izi, ndipo palibe tanthauzo la "mphamvu" ndi "ofooka" ndi kalasi inayake. Kachiwiri, sizitengera "nkhokwe zapamwamba" zotchulidwa mu ntchito yathu.
(2) Poyerekeza, kupsinjika mikhalidwe ya magulu a bolt sikulingaliridwe pano.

Kodi mumadziwa zochuluka motani zamphamvu kwambiri?
Dzinalo lonse la ma bolts apamwamba kwambiri opanga mphamvu ndi awiri olumikizirana awiriawiri, omwe nthawi zambiri samatchulidwa kuti ndi makambiki okwera.
Malinga ndi mawonekedwe okhazikitsa, amagawidwa: mutu waukulu wa heagon ndi zingwe zazingwe. Pakati pawo, mtundu wa zingwe za Torsion umangogwiritsidwa ntchito mu giredi 10,9.
Malinga ndi kalasi yogwira ntchito kwambiri, amagawidwa mu: Gawo 8.8 ndi kalasi 10.9. Pakati pawo, zolimbitsa thupi zazikulu zokhazokha zimapezeka mu Gawo 8.8. Munjira yodziwika, nambala ya nambala ya Decial mfundo ikusonyeza mphamvu yakuterera pambuyo pa chithandizo; Chiwerengerocho pambuyo pa gawo litatha kuwonetsa chiwerengero champhamvu champhamvu, ndiye kuti, kuchuluka kwa mtengo woyenerera kwa mphamvu yokwanira kwa phindu lenileni lamphamvu yayikulu. Gawo 8.8 limatanthawuza kuti kulimba kwamphamvu kwa ndodo ya bolt si kochepera 800mpa, ndi zokolola zokolola zili 0,8; Gawo 10.9 limatanthawuza kuti kulimba kwamphamvu kwa ndodo ya bolt sikuchepera 1000mmka, ndipo njira yokolola yamphamvu ndi 0,9.
Mwa kapangidwe kake, ma diameter a bolts ambiri amakhala m16 / M20 / M22 / M24 / M27 / M37 / M32 / M22 / M22 ndi mndandanda wachiwiri wosankha. Nthawi zambiri, m16 / M20 / M24 / M30 imagwiritsidwa ntchito makamaka.
Kapangidwe kakang'ono ka Shear, ma bolts okwera kwambiri amagawidwa: mphamvu yayikulu kwambiri yokakamiza ndi mtundu wamphamvu kwambiri molingana ndi zofunikira.
Kuchulukana kwa mtundu wamatsenga kumatengera kufooka kwa zolimba za mikangano yolumikizira mphamvu ndi kuchuluka kwa mikangano. Kupanga mikangano yokhala ndi dzimbiri yofiyira (kuwombera) ndikokwera kwambiri, koma kuchokera ku mawonekedwe enieni enieni, imakhudzidwa kwambiri ndi gawo lomanga. Mayuniti ambiri oyang'anira aganiza kuti mfundozo zitha kuchepetsedwa kuwonetsetsa kuti polojekitiyi ithe.
Kuchuluka kwa mtundu wokakamizika kumatengera mtengo wocheperako wa ma shear chiwopsezo cha bolt ndi kukakamizidwa kungakhale ndi ndodo ya bolt. Pankhani imodzi yokha yolumikizana, kumeta ubweya wa mikangano m16 ndi 21.6 ~ 4n.0.0.0.2 ~ 4.6 Kh, yomwe ndiyabwino kuposa mtundu wamakanganowo.
Pankhani ya kukhazikitsa, njira yolumikizira kupanikizika ndi yosavuta, ndipo kulumikizidwa kumangoyenera kutsukidwa kwa mafuta ndi dzimbiri. Malingaliro obwera chifukwa cha chitsogozo cha Axis ndi chosangalatsa kwambiri pakuyerekeza kwachitsulo. Mtengo wopangika wa mtundu wamatsenga ndi wofanana ndi 0,8 kanthawi kovuta, ndipo kapangidwe kake kake kake kake kake kamakhala kofanana ndi malo othandiza a spic screw. Zikuwoneka kuti pali kusiyana kwakukulu, koma mfundo ziwirizi ndizofanana.
Mukakhala ndi vuto lamphamvu komanso kusokonezeka kwa aximo nthawi yomweyo, njira yofunika kwambiri ya Shear kuti ikhale yopanda tanthauzo la anthu okwera pamutuwo lalikulu la kuchuluka kwa mphamvu yamphamvu yonyamula ndi screw to the tansile yonyamula anthu ochepera 1.0. Ndiye kuti, kuphatikiza katundu womwewo, kusungitsa malo osungirako mphamvu za mainchesi omwewo ndi okwera kuposa momwe mumakhalira ndi mphamvu.
Poganizira kuti mikangano yomwe ili yolumikizana imatha kulephera kubwereza zivomezi mobwerezabwereza, kumeta ubweya womwe ukukhala ndi mphamvu panthawiyi kumadalira kukana kwa mabatani ndi kupsinjika kwa mbale. Chifukwa chake, nambala ya seliam imalongosola njira yowerengera kuti ikhale yotsiriza ya kubereka kwathunthu kwamphamvu kwambiri.
Ngakhale mtundu wonyamula mavuto womwe umakhala ndi mwayi wopanga, mtundu wa kusokonekera kwa shear. Bowo la Bolt ndi bowo lolumikizana ndi bolt yofanana ndi ma bolts wamba wamba. Kuwonongeka kwa katundu ndi kwakukulu kuposa mtundu wamakanganowo. Chifukwa chake, mtundu wamphamvu kwambiri wonyamula mphamvu umagwiritsidwa ntchito makamaka pagawo la seomic, osalumikizana ndi gawo, komanso kulumikizana komwe sikunachitike.
Kugwiritsa ntchito malire a mitundu iwiriyi ndi yosiyana:
Kulumikizirana kwa mtundu wa mikangano kumatanthauza phokoso la osagwirizana ndi cholumikizira pansi pa katundu woyambira;
Kulumikizana kwa kupanikizika kumatanthauza phokoso pakati pa magawo olumikizirana ndi kuphatikiza kwadongosolo;
Ma bolts wamba
1. Ma bolts wamba amagawika m'mitundu itatu: a, b, ndi C. Awiri oyamba ndi oyenga bwino ndipo samagwiritsidwa ntchito kawirikawiri. Ma bolts wamba nthawi zambiri amatanthauza ma bolts wamba wamba.
2. Bolo wamba wamba lomwe limagwiritsidwa ntchito popanga zomangamanga ndi M16, M20, ndi M24. Ma Bolts ena olakwika pamakampani amakina amatha kukhala ndi mainchesi ambiri komanso kugwiritsa ntchito mwapadera.
Makamaka
3. Zachuma za ma bolts ambiri ndizosiyana ndi za ma bolts wamba wamba. Bolo lalikulu kwambiri nthawi zambiri limagwiritsidwa ntchito polumikizana kwamuyaya. Omwe amagwiritsidwa ntchito kawirikawiri ndi m16 ~ m30. Magwiridwe antchito okwera kwambiri ndi osakhazikika ndipo ayenera kugwiritsidwa ntchito mosamala.
4. Kulumikizana kwa Bolt kwa zigawo zikuluzikulu zanyumbayi nthawi zambiri kumapangidwa ndi mphamvu zambiri.
5. Mphamvu zokwera kwambiri zotumizidwa kuchokera ku fakitole sizigawidwa kukhala mtundu wa kupanikizika ndi mtundu wachinyengo.
6. Kodi ndichipembedzo choyipa kwambiri kapena cholimba chopanikizika kwambiri? M'malo mwake, pali kusiyana mu kapangidwe ndi njira yowerengera:
.
.
7. Pogwiritsa ntchito ntchito zothandiza, zomangira zomwe zimanyamula katundu wamphamvu kwambiri, makamaka pomwe katunduyo amachititsa kuti zinthu zizitha kupsinjika, zoopsa zokhala ndi mphamvu zambiri ziyenera kugwiritsidwa ntchito. Pakadali pano, zomwe sizigwiritsidwa ntchito ndi ma bolts zitha kugwiritsidwa ntchito ngati malo osungira. Kuphatikiza apo, kukakamizidwa kumapanikizika kwambiri kuyenera kugwiritsidwa ntchito kulumikiza kuti muchepetse mtengo wake.
Kusiyana pakati pa ma bolts wamba ndi ma bolts okwera kwambiri
8. Ma bolts wamba amatha kugwiritsidwanso ntchito, koma mabowo okwera kwambiri sangagwiridwenso ntchito.
9. Bolo lalikulu kwambiri limapangidwa ndi chitsulo chachikulu kwambiri (8.5s (8.8s), 20mmtib (10mmttib (10mmt)
10. Ma bolts wamba nthawi zambiri amakhala 4.4, 4.8, 5.6 ndi 8.8. Mphamvu zolimbitsa thupi nthawi zambiri zimakhala ndi 8.8 ndi 10.9, ndi 10.9 zofala kwambiri.
11. Bowo lolowera la bolt wamba silokulirapo kuposa lamphamvu kwambiri. M'malo mwake, chibowo cholumikizira cha bolt wamba chili laling'ono.
12. Mabowo a CLOGE C Scress nthawi zambiri amakhala 1.0 ~ 1.5mm yayikulu kuposa ma bolts.
.
. Katundu akakulirakulira, kusanja kwa chinsinsi kumachitika pakati pa mbale zolumikizira, ndipo kulumikizana kumadalira kukana kwa stracker ndi zovuta za ma bowo wamba, 1,5 ~ 1.5mm.
Anchor Color Bolts
15. Palibe kalasi ya nangula ma bolts, kusiyana kwakuthupi: Q235 ndi Q345. Nangula wogwiritsidwa ntchito kwambiri wogwiritsidwa ntchito kwambiri pamakina omanga ndi anchor.
. Kulankhula mosamalitsa, si ma balts. Nyundo ya anchin imagwiritsa ntchito M20 kapena M24.
. Kutalika kwa nangula kwa nthito kumodzi kumayenera kuphatikizidwa ndi mikangano pakati pa icho ndi konkriti, komanso mawonekedwe a nangula.
Kukula kwa mabowo ndi ma bolts
. Kulumikizana koteroko kuyenera kupewedwa, makamaka pamalumikizidwe ofunikira. Magawo ophatikizidwa ayenera kugwiritsidwa ntchito.
. Kuchuluka kwa kukana kokopera kumagwirizana kwambiri ndi njira yomanga, ndipo munthu ndi wamkulu. Ndikosagwira ntchito kuchititsa mayeso a Tnsile kuti ayesetse.
.
21. Kukula kwa mabowo ndi ma bolts a mankhwala kwenikweni ndi anchor ma balts. Nthawi zina, kukula kwa ma balts kapena ma ansalu a mankhwala mabanki amafunikira chifukwa sanayikidwe. Koma izi ziyenera kupewedwa popanga. Chifukwa anchor amangoyenera kukhazikitsidwa. Mwachitsanzo, nangula wa anchin wamalo. Chifukwa munjira imeneyi ndi momwe mungagwiritsire ntchito bwino kwambiri komanso mphamvu yotsimikizika. Kuphatikiza apo, mabowo obowola pambuyo pake nthawi zambiri amawononga zitsulo zopsinjika mu konkriti ndipo konkriti.
22. Mu lingaliro la konkriti, zigawo zikuluzikulu zomwe zinaikidwa mu konkriti zimatchedwa magawo oikidwa kale. Malinga ndi zolembedwa za ntchito yomanga, ma balts okumba sagwiritsidwa ntchito ngati makoma otchinga. Pa ntchito zatsopano zomanga, nangula wofuula amaletsedwa ndipo ayenera kukhazikitsidwa.
