Txias - tsim tawm sab nraud - nkhaus {2} ntug channel hlau
(Kuj tseem hu ua sab nraud - Hemmed channel, flared- channel, yob {} tsim tawm sab nraum zoov lip channel)

1. Cov Khoom Txheej Txheem

Cold-formed outward-curved-edge channel steel is a roll-formed C/U section whose flange edges are purposely curvedmus nraud(flared lossis hemmed ntawm lub vev xaib). Txoj kab nkhaus sab nraud tuaj yeem yog tus di ncauj me me, lub vojvoog flarius lossis ib lub ntsej muag yob nyob ntawm kev ua haujlwm thiab kev ua kom zoo nkauj. Qhov geometry no txhim kho ntug kev tiv thaiv, tsim kom muaj cov tshuaj tiv thaiv kom pom tseeb, thiab ua kom cov neeg sib sau ua ke thiab muab cov txiaj ntsig yooj yim rau cov nyiaj tau los ntawm kev txias.

2. Cov npe tshwj xeeb & cov variants

Outward - nkhaus flelled channel

Flared - ntug channel / sab nraud di ncauj c - channel

Hemmed -}} txiav tawm channel (ib nrab hem)
Cov kab sib txawv txawv ntawm: Daim di ncauj ntev (me me 5-10, ib lub txiv ntoo), thiab cov di ncauj rov qab (thiab daim di ncauj yog tsim hauv ib lossis ob kauj ruam.

3. Kev Tsim Kho Cov Txheej Txheem (Cov Ntsiab Lus)

Khoom pub:Txias -}} rolled coil → Theem → Txhim Kho Roll - Tsab ntawv sawv ntsug.

Sab nraud Curvature:tsim los ntawm cov chaw noj mov yob tshwj xeeb lossis xovxwm kawg rollers uas khoov cov flange ntug sab nraud mus rau qhov yuav tsum muaj radius / Angle.

Inline kev ua haujlwm:Punching / slotting, txhob txwm, khoov, thiab txiav - ntev ua ntej lossis tom qab daim di ncauj ua ntej daim di ncauj uas ua tau).

Xov:Debur, xaiv hemming / yob {-}} kev kho, kev kho mob sab nraud (pleev xim), ntim.

Txias txoj kev ua kom muaj qhov siab siab, rov ua haujlwm dua thiab ua haujlwm hnyav (txo qis me me ntxiv rau cov txiaj ntsig lub zog).

4. Ntaub Ntawv Raug & Txheej Txheem

Cov Hlau Hlau:Txias - rolled steels (DX51D Cov Qib (Q195, SGCCC), S235, siab dua} Lub zog CR / HR cov hlau rau kev thov.

Txheej txheem / tiav:zeb dub, kub {- dip galvanized (hdg), pppi / pvdf), hmoov rau}}

Pretreatment:Phosphaating lossis Chromate - pub dawb passivation rau cov xim nplaum.

5. Qhov tseeb tiag tiag & poj niam

Qhov tob (H):30 - 300 hli

Flarh Dav (B):15 - 150 hli

Sab nraud daim di ncauj / flare (l):5 - 25 hli (tuaj yeem yog ib qho kev maj mam flare lossis folded hem)

Thickness (t):0.8 - 6.0 hli (ib txwm muaj: 1.0 / 1.5 / 2.5 / 2.5 / 2.5 / 3.5 / 2.5 hli)

Lub vojvoog:r ≈ 1.5 × t → Cov tswv yim radii txog 8-10 hli nyob ntawm seb cov cuab yeej teeb tsa

Ntev:Txiav - rau - ntev ntawm 0.5 m txog rau ~ 12 m (raug 3/6 m)

Kev thev:liner ± 0.5 mm yog; ncaj tsawg dua los yog sib npaug rau 1 mm / m (lossis raws li pom zoo)

6. Vim li cas thiaj xaiv mus rau sab nraud- nkhaus npoo? (zoo)

Ntug Kev Tiv Thaiv & Corrosion Kuj:Flared / Hemmed Edges Vaj tse Cov txheej thiab txo cov txiav tau - ntug cheeb tsam.

Txhim Kho Cov Kua Dej / Kev Tswj Xyuas:Sab nraud curvature pab kom cov dej kom deb ntawm lub vev xaib lossis lub fasteners.

Txhais cov kabmob / clip nto:Sab nraud daim di ncauj muab lub rooj zaum zoo rau clips, ntsaws ruaj ruaj lossis txiav tej daim.

Kev nyab xeeb nthuav tawm cov npoo:Txo qhov kev pheej hmoo mob piv nrog txiav txiav txiav (tshwj xeeb yog hemmed).

Aesthetics:Zoo, ua tiav pom rau nthuav tawm kev teeb tsa.

Cov nyhuv stiffening:Sab nraud daim di ncauj nce hauv zos flarness Tiffness thiab pab kom cov ntug ntug ntawm cov kabmob.

7. Tus cwj pwm thiab lub cev

Sab nraud daim di ncauj nce flange tau siv tau zoo me ntsis thiab txhim kho cov hauv zos buckling kuj; Txawm li cas los xij, channel seem tseem qhib thiab raug rau - bracing tseem yuav tsum tau ntev rau spans ntev.

Txias kev tsim cov khoom me me - qhov tawv me me (me ntsis siab dua li niam txiv chev); Muab cov ntaub ntawv qib thiab cov neeg kho tshuab ua haujlwm thaum xaj.

8. Kab Zauv Ceev & Cov qauv ntsuas hnyav (tus lej -- tus lej)

Piv txwv li Ntu:h=100 hli, flange=40 hli (txhua), tuab} hli.

Theem ntsuas:

Flange thaj chaw txhua=40 × 3 =120 mm²→ 2 Flanges =240 mm².

Web Qhov Siab=100} - 2 3 =94 hli→ Www=94 × ×3 =282 mm².

Daim di ncauj tag nrho=2 × (10 × 3)=60 hli.

Tag nrho cheeb tsam = 240 + 282 + 60 = 582 mm².

Pawg ib lub ntsuas= 582 × 0.00785. Suav cov lej - los ntawm - tus lej:

582 × 0.007 = 4.074

582 × 0.00085 = 582 × (0.0008 + 0.00005) = 582×0.0008 + 582×0.00005 = 0.4656 + 0.0291 = 0.4947

Sum=4.074 + 0.4947 =4.5687 kg / m → ≈ 4.57 kg / m
