Sab nraud hexagonal ntsia liaj qhov rooj yog cov khoom siv hlau, tseem hu ua sab nraud hexagonal ntsia hlau, sab nraud hexagonal ntsia hlau, lossis sab nraud hexagonal ntsia liaj qhov rooj.

9. Lub zog muaj zog bolts feem ntau yog ua los ntawm cov hlau muaj zog (45 steel (8.8s), 20MmTiB (10.9s), uas yog prestressed bolts. Kev sib txhuam hom bolts yog pre-stressed nrog ib tug torque wrench, thiab siab hom bolts yog screwed tawm nrog ib tug plum blossom taub hau. raug nruj.

10. Ordinary bolts feem ntau yog qib 4.4, 4.8, 5.6, thiab 8.8. Lub zog muaj zog bolts feem ntau muab faib ua qib 8.8 thiab qib 10.9, nrog rau qib 10.9 feem ntau.

11. Cov ntsia hlau qhov ntawm cov bolts zoo ib yam yuav tsis tas yuav loj dua li cov bolts muaj zog. Qhov tseeb, qhov zoo tib yam bolt qhov yog me me.

12. Ordinary bolt A thiab B qib ntsia hlau qhov feem ntau tsuas yog 0.3-0.5 hli loj dua lub ntsia liaj qhov rooj. C-qib ntsia hlau qhov feem ntau yog 1.0-1.5 hli loj dua bolts.

13. Kev sib txhuam hom high-strength bolts kis loads los ntawm kev sib txhuam, yog li qhov sib txawv ntawm cov ntsia hlau thiab lub qhov ntsia hlau tuaj yeem ncav cuag 1.5-2.0mm.

Tus qauv quab yuam kis tau tus yam ntxwv ntawm lub siab bearing high-strength sab nraud hexagon bolts yog los xyuas kom meej tias nyob rau hauv ib txwm siv, lub shear quab yuam tsis tshaj qhov kev sib txhuam quab yuam, uas yog tib yam li cov kev sib txhuam hom high-strength bolts. Thaum lub load nce ntxiv, tus txheeb ze zawv zawg yuav tshwm sim ntawm cov hlau txuas. Kev sib txuas yog nyob ntawm qhov kev sib txhuam ntawm cov ntsia hlau thiab lub siab ntawm lub qhov phab ntsa kom xa cov quab yuam, uas yog tib yam li cov bolts zoo tib yam. Yog li ntawd, qhov sib txawv ntawm cov ntsia hlau thiab lub qhov taub yog me me, xws li 1.0 mus rau 1.5 hli.

Kem hauv paus thauj tog rau nkoj bolt

19. Anchor bolts tsis muaj qib, tsuas yog cov khoom siv: Q235 thiab Q345. Feem ntau siv thauj tog rau nkoj bolts hauv tsev cov qauv yog kem ko taw thauj tog rau nkoj bolts.

20. Kem ko taw thauj tog rau nkoj bolts tsis yog cov bolts zoo tib yam lossis qis dua rau cov ntsia hlau muaj zog. Hais lus nruj me ntsis, nws tsis yog rau bolts. Lub hauv paus thauj tog rau nkoj ntsia liaj qhov rooj feem ntau yog M20 lossis M24.

Cov qauv kev tsim khoom rau sab ko taw thauj tog rau nkoj bolts yuav tsum zoo ib yam li cov bolts zoo tib yam. Qhov ntev ntawm lub thauj tog rau nkoj ntsia liaj qhov rooj yuav tsum tau muaj feem xyuam rau cov kev sib txhuam quab yuam ntawm nws thiab cov pob zeb, nrog rau daim ntawv ntawm lub thauj tog rau nkoj ntsia liaj qhov rooj.

Expansion bolts thiab tshuaj bolts

22. Txawm hais tias nws yog expansion thauj tog rau nkoj bolts los yog chemical thauj tog rau nkoj bolts, lawv tsis yog cov ntaub ntawv kev twb kev txuas nyob rau hauv lub teb chaws tus qauv specifications, thiab xws li kev sib txuas yuav tsum tau zam, tshwj xeeb tshaj yog nyob rau hauv kev sib txuas tseem ceeb. Pre embedded qhov chaw yuav tsum tau siv rau txhua tus.

23. Lub expansion thauj tog rau nkoj ntsia liaj qhov rooj feem ntau yog nyob ntawm qhov qhib ntawm lub expansion yeeb nkab txee thiab kev sib txhuam quab yuam generated los ntawm cov pob zeb kom tiv thaiv rub. Qhov loj ntawm lub zog tensile yog ze ze rau txoj kev tsim kho, thiab muaj cov tib neeg tseem ceeb cuam tshuam. Yog li ntawd, kev sim tensile los ntawm kev soj ntsuam random kuj tsis muaj txiaj ntsig.

24. Tshuaj anchor bolts yog tsim los ntawm kev xuas nrig ntaus nrog lub tshuab xuas nrig ntaus, ntxig rau tus pas nrig, thiab tom qab ntawd txhaj tshuaj slurry kom ua tiav cov nyhuv anchoring. Hom hom xws li Huiyu thiab Heineken.

Expansion bolts thiab tshuaj bolts tiag tiag yog cov khoom thauj tog rau nkoj. Qee zaum, cov bolts nthuav dav lossis cov khoom siv tshuaj lom neeg yog xav tau vim tias lawv tsis tau muab tso ua ntej. Tab sis qhov xwm txheej no yuav tsum tau zam hauv kev tsim. Vim hais tias thauj tog rau nkoj bolts yuav tsum tau pre embedded. Piv txwv li, kem ko taw thauj tog rau nkoj bolts. Vim tias tsuas yog nyob rau hauv txoj kev no peb tuaj yeem ua kom pom qhov adhesion thiab kev ntxhov siab. Ntxiv mus, xuas nrig ntaus qhov tom qab feem ntau cuam tshuam rau cov steel tuav thiab cov pob zeb hauv pob zeb
