1. Cov ntsiab lus

Qib III RebarYog lub siab - lub zog, ribbed (deformed) steel board, zoo dua kev ua siab loj. Nws sawv cev rau kev txhim kho tseem ceeb tshaj qib kuv (me me) thiab qib me me (nruab nrab} {} {} {

Qib III kev txhawb zog yog siv dav hauvHigh -}}}}}} rise tsev, txoj kev loj, muaj nroj tsuag, thiab seismic {{>> resistant qauv qauv, qhov twg ob lub zog thiab ductility yog qhov tseem ceeb. Nyob ntawm lub teb chaws tus qauv, qib III feem ntau sib haum rau niaj hnub cov rebar tsim xws liHRB400 / HRB500 (Suav Teb), Fe500 / FE550 (Is Nrias teb), lossisQib 60/75 (Asmeskas).

2. Cov ntaub ntawv faib tawm thiab cov qauv

"Qib III" yog ib qho kev faib tawm uas nquag siv rau hauv cov laus lossis hauv zos; Cov kev yuav tsum muaj cov kev yuav tsum muaj nyob ntawm tus qauv hauv tebchaws. Hauv qab no yog cov qauv sib npaug thiab cov qhab nia siv thoob ntiaj teb:

Yeej ib txwm hais covTxheem sivthiab cov kev yuav tsum muaj cov neeg kho tshuab es tsis txhob siv cov lus dav dav "qib III."

3. Neeg kho tshuab thiab lub cev muaj zog

Raug Ranges rau qib III / siab - lub zog deformed rebar (tseeb tus nqi sib txawv los ntawm cov qauv):

Yield zog (FY):400-550 MPa

Tensile lub zog (fu):540-650 mpa

Elongation:Ntau dua los yog sib npaug rau 10-16%

Elastic modulus:Tom ntej no 200 GPA

Ntawj ntom:7,850 kg / mp

Daim Ntawv:Deformed (Ribbed) nto rau cov neeg kho tshuab siab tshaj

Ductility:Txhim kho dua qib qib II, haum rau seismic thiab cyclic chaw thau khoom

Qib Iii cov kab ua haujlwm pomCov cwj pwm zoo heev, muaj lub zog nqus nqus, thiab xwm yeem weldability thaum tsawg}} roj carbon stiety siv.

4. Qhov ntev thiab muab ntau

Nominal Diameters:6 hli - 50 hli

Cov diamiters ua ntau yam:8, 10, 12, 16, 20, 25, 28, 25, 40 hli

Ntev:6 m / 9 m / 12 m (tus qauv); kev cai txiav - rau - ntev muaj

Nto tas:

Zeb dub (raws li -} rolled)

Epoxy coated (rau cov tubrog nkoj lossis tshuaj ib puag ncig)

Kub - dip galvanized (rau corrosion tsis kam)

Daim ntawv thov stainless (rau cov ntawv thov kev ua tsis taus)

Kev thev:Ib tus qauv (feem ntau ± 0.5-1% hauv txoj kab uas hla; ± 50 hli ntev)

5. Cov yam ntxwv tseem ceeb thiab cov txiaj ntsig

Siab zog - rau - qhov hnyav. Piv:Tso cai rau txo cov bar thiab qhov sib nrug yam tsis muaj kev sib txawv ntawm cov qauv txheej txheem.

Zoo heev Bondy zog:RIBBED PROFILE muab kev sib txhuam siab heev thiab tshuab siv tshuab hauv cov pob zeb.

Txhim kho Ductility:Khaws tau elongation txawm tias nyob rau theem siab dua lub zog, zoo tagnrho rau cov kab seismic.

Qeeb thiab kev cuam tshuam Kuj:Haum rau cov ntaub ntawv txuas ntxiv thauj khoom (txuas hniav, cov plag tsev).

Zoo Weldability thiab Formaty:Rau tsawg -} cov pa roj carbon ntau lossis tswj cov tshuaj muaj kuab.

Tus Qauv Nyiaj Txiag:Txo cov hlau noj thiab cov vaj tse cov npog tuab.

6. Cov ntawv thov raug

Reinforced Pob ZebTxhua, kab teeb, slabs, thiab shear phab ntsanyob rau hauv high -} Rose vaj tse

Txuas hniav, ya mus, kev sib tw, thiab tuav phab ntsa

Kev lag luam thiab marine qauvRaug rau qaug zog lossis xeb

Seismic - tsis kam ntasthiab retrofitting tej yaam num

Cov Cuab Yeej Siv Hluav Taws Xob thiab Lub Hauv Paus Haujlwm(piles, capissons, pawg pawg)

7. Xam Piv Txwv - Qhov hnyav rau ib lub ntsuas

Txhawm rau kwv yees ib qho loj rau ib lub 'meter', siv:
[
m {=} rho \\ frac {\\ pi d ^ -} \\ Time \\ Time \\ Sijhawm D ^ 2
]
(qhov twgd= bar txoj kab uas hauv hli)

Piv txwv li:Rau 16 hli Qib III Rebar:
[
m {= 0.006165 \\ sij hawm (16) ^ {{\\} \\} \\} \\} \\} \\} \\}
]

Yog li, ib 12 m bar hnyav kwv yees li:
1.578 × 12 = 18.94 kg

Qhov hnyav siv rau ib lub ntsuas:
10 hli=0.617 kg / m
12 hli=0.888 kg / m
16 hli=1.578 kg / m
20 hli=2.466} kg / m
25 hli {= 3.854 kg / m
32 hli=6.313 kg / m

8. Kev sib xyaw ua ke, kov, thiab vuam

Dabtsi yog khoov:Txias khoov rau ib tus qauv; Txo qhov tsawg kawg nkaus khoov diameters (piv txwv li, 4-6 × bar txoj kab no).

Tej:Neeg kho tshuab txiab los yog abrasive saws; nplaim taws txiav tsis pom zoo rau coated tuav.

Vuam:Tsuas yog Weld cov qhab nia tsim "weldable" (piv txwv li aytm A706, HRB400E). Txheeb xyuas cov kev siv tshuaj thiab preheat raws li xav tau.

Cia:Cia kom tawm hauv av thiab npog kom tiv thaiv xeb; Siv cov cav ntoo ntawm cov khaubncaws sab nraud povtseg.

Kev tso kawm:So kom huv ntawm cov roj, av nkos, lossis ntsuas ua ntej kev tso chaw.
