Taw qhia rau Seismic-Resistant Duct Bracing

Seismic-Resistant duct bracing yog ib qho khoom siv txhawb nqa seismic siv hauv kev tsim hluav taws xob engineering los kho qhov cua thiab cua txias duct systems. Los ntawm kev tsim qauv tsim, nws txwv txoj kab rov tav / ntsug ntawm cov ducts thaum muaj av qeeg, tiv thaiv cov ducts los ntawm kev ntog, tawg, los yog raug kev puas tsuaj los ntawm kev sib tsoo, yog li txo qis kev puas tsuaj rau theem nrab (xws li cov neeg raug tsim txom, cov khoom puas tsuaj, thiab lub qhov cua tuag tes tuag taw), ua kom lub tsev ua haujlwm muaj kev nyab xeeb, thiab ua kom muaj kev ruaj ntseg tom qab {2}kev puas tsuaj.

1. Load-cov kabmob txhawb nqa: Txhawb nqa qhov hnyav ntawm cov ductwork thiab nruab nrab (xws li, huab cua, flue gas), ua kom ruaj khov txhua hnub ntawm cov ductwork;

2. Seismic bracing: Ib qho tseem ceeb ntawm seismic- tiv thaiv tiv thaiv, muaj xws li transverse bracing (tiv thaiv kab rov tav seismic rog) thiab longitudinal bracing (resisting longitudinal seismic rog). Nws txuas mus rau lub ductwork thiab lub ntsiab lub tsev qauv ntawm cov ces kaum (xws li, 45 degree, 30 degree) mus hloov seismic loads;

3. Cov khoom sib txuas: suav nrog cov clamps, U-clamps, threaded rods, thiab kho cov khoom, siv los kho cov ductwork rau kev txhawb nqa, hloov mus rau ducts ntawm cov kab sib txawv thiab cov duab (round / rectangular);

4. Anchors: Xws li expansion bolts thiab chemical anchors, ruaj khov kho qhov kev txhawb nqa rau lub ntsiab lub tsev qauv (xws li, pem teb slabs, kab teeb, phab ntsa), kom ruaj ntseg tag nrho.

Kev tsim thiab kev teeb tsa yuav tsum nruj me ntsis ua raws li lub teb chaws tus qauv GB 50981-2014 "Code for Seismic Design of Building Mechanical and Electrical Engineering". Cov kev cai tshwj xeeb muaj xws li:

Seismic fortification intensity: Txiav txim siab qib seismic thiab load txwv ntawm kev txhawb nqa ncej raws li seismic fortification siv ntawm thaj chaw uas lub tsev nyob (yuav tsum tau tsim nyob rau hauv cov cheeb tsam uas seismic siv 6 degrees thiab saum toj no);

Qhov sib nrug thiab thauj khoom: Tsim qhov kev txhawb nqa ncej sib nrug raws li qhov loj ntawm cov kav dej (inch / sab ntev), qhov hnyav (nrog rau qhov nruab nrab), kev teeb tsa qhov siab, thiab seismic fortification qeb (piv txwv li, Chav A, B, thiab C lub tsev). (Feem ntau, qhov sib nrug deb tsawg dua lossis sib npaug li 9m, thiab qhov sib nrug ntev tsawg dua lossis sib npaug li 18m; qhov sib txawv tshwj xeeb yuav tsum tau txiav txim siab los ntawm kev suav);

Kev taw qhia quab yuam: Cov ncej txhawb nqa yuav tsum ib txhij tiv thaiv kab rov tav seismic rog (sab sab / ntev) thiab ntsug seismic quab yuam (hauv qee qhov siab - siv qhov chaw). Lub kaum sab xis ntawm kab pheeb ces kaum yuav tsum ua kom zoo tshaj plaws ntawm kev sib kis ntawm lub zog (piv txwv li, kab rov tav kab pheeb ces kaum bracing yuav tsum yog nyob ntawm 45℃± 15℃rau lub dav hlau kab rov tav). IV. Muaj feem xyuam Scenarios Dav dav siv rau ntau lub tsev uas yuav tsum tau lav qhov cua:

Pej xeem vaj: tsev kho mob, khw malls, tsev so, subways, tshav dav hlau, thiab lwm yam. (Cov pej xeem ceev, siab heev nyob rau tom qab-kev puas tsuaj qhov cua);

Cov tsev muaj: Factories, cleanrooms, thiab lwm yam. (Complex duct systems, precision khoom, vibration puas yuav tsum tau zam);

High-Rise Buildings: Super high-cov tsev ua haujlwm nce siab, cov tsev nyob (High duct installation qhov siab, muaj kev pheej hmoo ntawm lub caij nplooj zeeg);

Qhov Chaw Tshwj Xeeb: Cov phiaj xwm tiv thaiv pej xeem, cov chaw khaws ntaub ntawv, thiab lwm yam.

Cov Khoom Tseem Ceeb: Feem ntau kub-dip galvanized steel (Q235B / Q355B), muaj lub zog siab (lub zog tensile Ntau dua lossis sib npaug rau 345MPa), kev tiv thaiv corrosion (zinc txheej thickness ntau dua lossis sib npaug rau 85μm), thiab qaug zog ua haujlwm. Cov hlau tsis muaj steel tuaj yeem siv rau hauv qee qhov siab -cov av noo / corrosive ib puag ncig (xws li hauv qab daus, chaw ua haujlwm tshuaj lom neeg);

• Kev Kho Hniav: Kub-dip galvanizing / txias galvanizing + txau, txhim kho huab cua tiv thaiv thiab ua kom muaj kev pabcuam lub neej synchronized nrog lub tsev qauv (Ntau dua lossis sib npaug rau 50 xyoo).

1. Earthquake Resistance and Disaster Mitigation: Los ntawm kev txwv txoj kab xaim, qhov kev pheej hmoo ntawm cov ducts vau thiab tawg los ntawm av qeeg raug txo, ua raws li lub hauv paus ntsiab lus tsim seismic "tsis muaj kev puas tsuaj hauv av qeeg me me, kho tau hauv av qeeg me ntsis, thiab tsis muaj kev sib tsoo hauv av qeeg loj."

2. System Stability: Hauv kev siv txhua hnub, nws txo cov suab nrov uas tsim los ntawm cov kav dej vibration (xws li kev ua haujlwm kiv cua thiab kev cuam tshuam ntawm huab cua), ncua kev pab cuam lub neej ntawm cov ducts thiab cov khoom siv (xws li cua li qub thiab cov cua tawm).

3. Kev Ua Raws Cai: Ua tau raws li qhov yuav tsum tau ua ntawm lub teb chaws cov qauv xws li GB 50981-2014 thiab GB 55036-2022, uas yog qhov tsim nyog rau kev tsim kev lees paub.

4. Customized Adaptation: Customized designs can be made according to duct size (round/rectangular), weight (single duct section Tsawg dua los yog sib npaug li 200kg), thiab installation method (sspended/wall-mounted/beam-mounted) to ensure load- bearing capacity and seismic performance matching. VII. Qhov sib txawv ntawm Ordinary Supports: Ordinary duct txhawb nqa tsuas yog dais static load- bearing functions (lub luj ntawm lub duct nws tus kheej thiab qhov nruab nrab), hos seismic txhawb ntxiv seismic bracing lug rau lub load- bearing foundation. Los ntawm kev sib txuas ntawm cov bracing thiab cov qauv tseem ceeb ntawm lub tsev, lawv tuaj yeem tiv taus ob qho tib si kab rov tav (tseem ceeb) thiab ntsug seismic rog, ua tiav ob txoj haujlwm ntawm "load-cov kabmob + seismic tsis kam".

1. Customized Design: Ib tus kws tshaj lij engineers yuav tsum ua cov kev ntsuas kev ntxhov siab raws li qhov ntsuas qhov ntsuas (qhov loj me, qhov hnyav, huab cua tshaj tawm), lub tsev seismic tsis kam (piv txwv li, seismic fortification siv 6 degrees lossis siab dua rau Chav Kawm C), thiab qhov chaw (piv txwv li, nqaj qauv, cov kav dej sib tshuam) kom tsis txhob muaj "ib-} loj" {8}.

2. Kev sib txuas ruaj ntseg: Cov thauj tog rau nkoj yuav tsum tau muab tso rau hauv lub tsev loj (cov khoom siv lub zog loj dua lossis sib npaug ntawm C30) kom ntseeg tau tias rub- tawm thiab shear quab yuam raws li cov qauv. Kev sib txuas ntawm kab pheeb ces kaum thiab cov kav dej / kev txhawb nqa yuav tsum tau kho nrog bolts; welding yog txwv tsis pub (kom tsis txhob ua kom tsis muaj zog steel).

3. Dynamic Verification: Tom qab kev teeb tsa, kev ntsuas kev thauj khoom (piv txwv li, kev ntsuas kev thauj khoom zoo li qub, kev sim kev co simulation) yuav tsum tau ua kom paub tseeb tias qhov kev hloov pauv ntawm kev txhawb nqa raws li kev tsim seismic quab yuam tsawg dua los yog sib npaug rau cov qauv txwv (feem ntau tsawg dua lossis sib npaug ntawm 150mm).

Seismic-cov kev txhawb nqa ducts yog ib qho tseem ceeb ntawm "seismic kev tiv thaiv kab" ntawm lub tsev niaj hnub electromechanical systems. Los ntawm kev tsim qauv tsim qauv thiab kev teeb tsa tus qauv, kev ua kom tsis muaj zog ntawm qhov cua thiab cua txias tshuab tuaj yeem txhim kho tau zoo, muab kev txhawb nqa tseem ceeb rau kev ruaj ntseg hauv tsev thiab tom qab- kev tiv thaiv kev puas tsuaj.
