Bolt yakunja ya hexagonal ndi chowonjezera chachitsulo, chomwe chimadziwikanso ngati screw yakunja ya hexagonal, screw yakunja ya hexagonal, kapena bawuti yakunja ya hexagonal.

9. Maboti amphamvu kwambiri nthawi zambiri amapangidwa ndi zitsulo zolimba kwambiri (45 zitsulo (8.8s), 20MmTiB (10.9s), zomwe ndi mabawuti okhazikika. Maboti amtundu wa friction amalumikizidwa kale ndi wrench ya torque, ndipo ma bolts amtundu wamphamvu amawongoleredwa ndi maluwa a plums (8.8s), 20MmTiB (10.9s), omwe amakhala ma bolts okhazikika. Maboti amtundu wa friction amakhomedwa kale ndi wrench ya torque, ndipo ma bolts amtundu wamphamvu amawongoleredwa ndi maluwa a plums (8.8s), 20MmTiB (10.9s), omwe ndi mabawuti okhazikika. Zitsulo zamtundu wa friction zimakhazikika kale ndi wrench ya torque, ndipo ma bolts amtundu wamphamvu amapukutidwa ndi maluwa a maula amaluwa wamba. chomangika.

10. Mabawuti wamba nthawi zambiri amakhala giredi 4.4, 4.8, 5.6, ndi 8.8. Maboti amphamvu kwambiri nthawi zambiri amagawidwa kukhala giredi 8.8 ndi giredi 10.9, pomwe giredi 10.9 ndi omwe amapezeka kwambiri.

11. Mabowo a ma bolts wamba sangakhale okulirapo kuposa ma bolts amphamvu kwambiri. Ndipotu mabowo wamba amakhala ochepa.

12. Boloti wamba A ndi B mulingo wa screw bowo nthawi zambiri amangokulira ndi 0.3-0.5mm kuposa bawuti. Mabowo a C-grade screw nthawi zambiri amakhala akulu 1.0-1.5mm kuposa mabawuti.

13. Mabawuti amtundu wamphamvu kwambiri amatumiza katundu kudzera mukukangana, kotero kusiyana pakati pa wononga ndi bowo la wononga kumatha kufika 1.5-2.0mm.

Makhalidwe a mphamvu yopatsira mphamvu ya kupanikizika kokhala ndi mphamvu zapamwamba zakunja za hexagon ndizoonetsetsa kuti pansi pa kugwiritsidwa ntchito bwino, mphamvu ya shear sichidutsa mphamvu yomenyana, yomwe imakhala yofanana ndi yamtundu wa friction yamphamvu kwambiri. Pamene katundu ukuwonjezeka kwambiri, wachibale kutsetsereka zidzachitika pakati kulumikiza mbale. Kulumikizana kumadalira kukana kukameta ubweya wa wononga ndi kukakamiza pakhoma la dzenje kufalitsa mphamvu, zomwe zimakhala zofanana ndi mabawuti wamba. Choncho, kusiyana pakati pa wononga ndi wononga dzenje ndi yaying'ono pang'ono, kuyambira 1.0 mpaka 1.5mm.

Bawuti ya nangula ya Column base

19. Maboti a nangula alibe kalasi, zida zokha: Q235 ndi Q345. Zomangira za nangula zomwe zimagwiritsidwa ntchito kwambiri m'nyumba zomangira ndi ma bolt a nangula wa phazi.

20. Mipiringidzo ya nangula ya phazi la mgawo si mabawuti wamba kapena otsika poyerekeza ndi mabawuti amphamvu kwambiri. Kunena zowona, sizikhala za mabawuti. Boti ya nangula yoyambira pansi nthawi zambiri imakhala M20 kapena M24.

Miyezo yopangira ma bawuti a nangula wa phazi lazanja iyenera kukhala yofanana ndi ya mabawuti wamba. Kutalika kwa bawuti ya nangula yogulidwa pamzake kuyenera kukhala kogwirizana ndi mphamvu yakukangana pakati pake ndi konkriti, komanso mawonekedwe a nangula.

Maboti okulitsa ndi ma bolt amakhemikali

22. Kaya ndi ma bolts a nangula owonjezera kapena ma bolt a nangula amankhwala, sali mafomu olumikizirana muzofunikira zapadziko lonse lapansi, ndipo kulumikizana koteroko kuyenera kupewedwa, makamaka pazolumikizana zofunika. Zigawo zomwe zidaphatikizidwa kale ziyenera kugwiritsidwa ntchito kwa onse.

23. The kukulitsa nangula bawuti makamaka amadalira kutsegula kwa kabati chitoliro chokulitsa ndi mphamvu frictional kwaiye konkire kukana kukoka. Ukulu wa mphamvu zomangika zimagwirizana kwambiri ndi ntchito yomanga, ndipo pali zinthu zambiri zaumunthu zomwe zimakhudzidwa. Chifukwa chake, kuchita zoyeserera movutikira poyang'ana mwachisawawa kulinso kopanda ntchito.

24. Mankhwala opangira nangula amapangidwa ndi kubowola mabowo ndi makina okhomerera, kulowetsa ndodo ya bolt, ndiyeno jekeseni slurry wa mankhwala kuti akwaniritse nangula. Mitundu wamba monga Huiyu ndi Heineken.

Maboti okulitsa ndi ma bolt amakhemikali kwenikweni ndi a nangula. Nthawi zina, mabawuti okulitsa kapena ma nangula amankhwala amafunikira chifukwa sanazikepo. Koma izi ziyenera kupewedwa pakupanga. Chifukwa ma bolts a nangula ayenera kuphatikizidwa. Mwachitsanzo, ma bawuti a nangula wa phazi la mzati. Chifukwa mwanjira imeneyi tingathe kuonetsetsa mulingo woyenera adhesion ndi nkhawa. Komanso, kubowola mabowo pambuyo pake nthawi zambiri kumakhudza mipiringidzo yachitsulo yokhazikika ndi konkriti mu konkriti
