BS 1139 Yeeb Nkab

Tianjin Lined Industrial Co., Ltd yog ib qho ntawm cov neeg tsim khoom thiab cov khoom lag luam BS 1139 yeeb nkab hauv Suav teb. Thov koj xav tau kev yuav khoom zoo BS 1139 yeeb nkab los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab tus nqi tsim nyog muaj.

BS 1139 yeeb nkab txheem thiab cov khoom muaj feem cuam tshuam.

Ua ntej tshaj plaws, nws yog qhov tsim nyog los qhia meej ib qho tseem ceeb: BS 1139 yog cov qauv ntawm cov qauv siv rau scaffolding thiab lub hom phiaj. Nws tsis yog tib tus qauv, thiab "BS 1139 yeeb nkab" koj tau hais tshwj xeeb rau ib feem ntawm cov kav hlau cuam tshuam hauv cov qauv no.

Ntawm tam sim no, BS 1139 tau hloov los ntawm cov qauv hauv European (En cov qauv), tab sis cov qauv no feem ntau yog cov khoom siv hauv tebchaws Askiv thiab cov ntsiab lus ntawm cov ntsiab lus thiab cov kev xav tau. Nkag siab BS 1139 yog lub hauv paus rau kev nkag siab cov qauv tam sim no.

BS 1139 cov qauv ntawm cov qauv yog muab faib ua ntau ntu, ntawm cov tseem ceeb tshaj plaws yog:

• BS 1139-1: Qhia meej txog qhov yuav tsum tau rau cov kav hlau hlau uas siv rau hauv scaffolding thiab lub hom phiaj dav dav. Nov yog cov ntsiab lus tseem ceeb uas peb xav qhia.
• BS 1139-2: Nws ua qauv rau cov cai rau scaffold couplings.
• BS 1139-3: Nws ua qauv rau cov kev cai rau Scaffolding Camts.
• BS 1139-4: Qhia txog cov kev xav tau rau cov laug cam.

Cov xwm txheej tam sim no: BS 1139 tau hloov los ntawm cov qauv European hauv qab no (en), uas tau saws raws li cov qauv hauv tebchaws Askiv thiab yog tus lej BS En:

• Cov kav hlau steel: BS en 10219- 1 thiab bs en 10219-2 (khaub thuas-tsim welded cov qauv welded)
• Scaffolding Couplings: BS EN 12811-1

Txawm hais tias nws tau hloov, hauv kev sib txuas lus hauv kev lag luam hauv kev lag luam, cov qauv yeeb nkab uas tau raws li cov qauv yeeb nkab qauv

Cov qauv no yaum nruj heev thiab tshwj xeeb cov tseev kom zoo thiab cov kev xav tau ntawm cold {} Tsim kom muaj kev nyab xeeb rau lawv txoj kev nyab xeeb, kev ntseeg tau thiab interchangility thiab interchangility.

Cov kev yuav tsum muaj cov kev cai muaj:

1. Qhov ntev thiab thev taus

• Nws qhia meej cov qhov ntev meej ntawm cov uas hla (OD), phab ntsa tuab (wt), thiab muaj kev cia siab rau cov neeg muaj kev cia siab).
• Qhov ntau thiab tsawg thiab tsawg cov taub muaj xws li: txheej inch 48.3 hli (42.7mm, thiab lwm yam. Cov duab tuab ntawm phab ntsa feem ntau yog 3.2mm, 4.0mm, thiab lwm yam.
• Kev thev taus nruj kom ntseeg tau tias kev sib txuas ntawm cov kav dej (xws li thaum muab cov tes tsho lossis txuas nrog lub ntsej muag kom nruj, lav tau cov rigidity thiab ruaj khov ntawm tus qauv.

2. Cov Khoom Siv

• Cov hlau tsis muaj feem ntau yog ua los ntawm tsis - Cov hlau uas muaj kev sib tw tau, xws li S275J0H lossis S255J2H (nyob rau hauv raws li EN 10219). Cov lej no sawv cev rau cov txiaj ntsig lub zog ntawm cov hlau (xws li 235, 275, 355 n / mmol) thiab cuam tshuam cov tawv.
• Cov ntaub ntawv yuav tsum muaj weldability zoo, formability thiab ib co℃ntawm kev nruj (tshwj xeeb tshaj yog nyob rau hauv qis -}} qhov chaw ib puag ncig).

3. Kev tsim qauv:

Nws yuav tsum yog ua los ntawm kev kub hlob txias thiab arc vuam.

Weld leeg yuav tsum ua kom tiav, txuas ntxiv mus thiab fuse nrog lub hauv paus hlau. Lub cheeb tsam weld yuav tsum tau txiav kom nws tsis cuam tshuam los saum npoo ntawm cov yeeb nkab lub cev kom ntseeg tau tias cov fasteners du.

4. Cov Khoom Siv Neeg Kho Tshuab:

• Paib lub zog:Qhov tsawg kawg nkaus yuav tsum tau ua, piv txwv, cov paib muaj zog ntawm S235 yuav tsum tsis pub tsawg tshaj li 235 N / MM². Qhov no yog qhov taw qhia tseem ceeb rau kev laij cov kabmob ntawm cov qauv.
• TUa kom lub zog (tensile lub zog):Qhov tsawg kawg nkaus uas yuav tsum tau ua, piv txwv li, lub zog tensile ntawm S235 yog ntawm 360 thiab 510 n / mm².
• Elongation:Nws qhia txog qhov tsawg kawg nkaus ntawm elongation ntawm pob txha lov, pom txog kev ductility ntawm cov khoom, uas yog qhov tseem ceeb rau kev nyab xeeb (kom tsis txhob tawg tawg).

5. Kuaj thiab tshuaj xyuas:

• Siab xeem: Cov yeeb nkab steel yuav tsum muaj peev xwm nrog nrog qee yam dej sab hauv uas tsis muaj dej xau lossis tawg.
• Kaj ntsuam xyuas:Ntu ntawm cov yeeb nkab yog pluav rau ib qho kev ncua deb los sim nws lub ductility thiab weld zoo. Thaj chaw weld yuav tsum tsis txhob tawg ua ntej.
• Khoov xeem:Txhawm rau tshuaj xyuas cov qauv ntawm cov khoom siv.
• Kev Ntsuas Qhov Kev Ntsuas:Txhawm rau tshuaj xyuas cov khoom siv tawv ntawm cov ntaub ntawv ntawm cov kub tsawg.
• Cov tsos thiab zoo nkauj:Cov yeeb nkab yuav tsum tsis muaj qhov tsis xws luag uas muaj kev phom sij rau daim ntawv thov. Feem ntau nrog txheej txheej ntawm kev tiv thaiv zeb nplai lossis siv nrog cov xim tiv thaiv.

6. Cim cim thiab ntawv pov thawj:

• Txhua cov yeeb nkab lossis txhua pob ntawm cov kav dej yuav tsum muaj qhov tseeb thiab tsis yog {}} Cov cim npe, tus lej BS EN 10219), qib steel, thiab lwm yam.
• Cov chaw tsim khoom yuav tsum muab daim ntawv pov thawj ua pov thawj los ua pov thawj tias cov khoom lag luam uas ua raws li cov qauv.

Piv nrog rau tib neeg welded steel kav lossis dub steel kav, qhov tsis sib xws ntawm BS 1139 (thiab nws cov qauv tom ntej) kav dej nyob hauv:

1. Siab zog - rau - qhov hnyav. Piv: Thaum ua kom lub zog siab (xws li tau tawm los lub zog ntawm 355MPA), ua cov qauv teeb meem thiab muaj cov kabmob muaj zog}}} bearing muaj peev xwm.

2. EXtremely siab siab qhov tseeb thiab xwm yeem:Qhov no yog nws feem ntau cov ntsiab lus. Strict theeride inch thiab roundness tas vim muaj ntau hom scaffs thiab txhim khu kev qha cov ntsiab lus sib txuas, uas yog qhov tseem ceeb ntawm kev tsim kho kev tsim kho.

3. Cov Khoom Siv Ntsuas Cov Khoom Siv Metallurgical thiab Cov Neeg Kho Tshuab:Nws tsis tsuas yog hais kom muaj zog tab sis kuj tseem du thiab tawv, kom cov yeeb nkab tuaj yeem deform (ceeb toom) nyob rau hauv sab nraud quab yuam dua li sai sai.

4. Nruj ua tau zoo siab lees tias cov txheej txheem: Los ntawm cov khoom siv raw rau cov khoom tiav, txhua tus yauv ua kom nruj thiab tshuaj xyuas, thiab xav tau cov ntawv pov thawj los ntawm kev ntseeg tau.

5. Qauv kho thiab University:Raws li cov txheej txheem thoob ntiaj teb tau pom zoo, nws ua rau cov khoom sib txawv los ntawm cov chaw tsim khoom sib txawv, ua kom haum, thiab kev tsim txua ntawm lub ntiaj teb nplai.

Vim nws qhov kev ua tau zoo tshaj plaws, daim ntawv thov ntawm BS 1139 steel kav muaj deb tshaj li cov ib txwm ua teb:

1. Scaffolding System:Nws yog qhov tseem ceeb tshaj plaws thiab ib txwm application. The vertical rods, horizontal rods and diagonal braces that constitute various systems such as coupler-type scaffolding and portal scaffolding.

2. Pab txhawb cov qauv:Kev txhawb nqa cov qauv ib ntus thiab cov tshuab ua formwork siv rau cov chaw tsim khoom.

3. Cov Ntawv Thov Kev Tsim Kho

• Lub tsev qauv:Ru trusses, spatial grid lug, canopies, handrails thiab cov tsheb nqaj hlau, thiab lwm yam. Nws cov ntoo khaub lig zoo nkauj- seem} seem thiab cov txheej txheem txheej txheem txheej txheem yog cov neeg txawj txua los ntawm kws keej thiab engineers.

• Theem thiab Exhibition:Siv rau Tsev Theem Trusses, teeb pom kev zoo thav lug thiab cov qauv ib ntus rau cov kev sib hais kwv txhiaj, ua yeeb yaj kiab thiab chaw ua yeeb yam. Nws lub teeb yuag thiab nrawm sib dhos cov yam ntxwv yog qhov haum rau cov teb no.

4. Agricultural thiab Industrial khoom:Siv rau kev tsim khoom lag luam machinery thav ntawv, cia cov txee cia, cov vaj tsev yooj yim, cov neeg tiv thaiv cov qauv, thiab lwm yam.

5. Tsim thiab Tsim:Vim nws yooj yim txiav thiab vuam cov zog, feem ntau nws yog feem ntau siv los ntawm cov tsim qauv thiab cov kws ua yeeb yam los ua cov rooj tog, duab puab thiab muaj ntau yam tsiaj txhu muaj tswv yim.

BS 1139 cov yeeb nkab yog qhov tseem ceeb ib txheej kev ua kom nruj zoo rau cov khaub thuas {1} Taug kev wollded hollow hlau kav. Nws cov tseem ceeb tus nqi nyob rau hauv kom ntseeg tau tias cov qauv kev nyab xeeb ib ntus lossis kev ntseeg siab tshaj plaws, kev ntseeg tau zoo tshaj plaws thiab nruj me ntsis kev tswj hwm. Txawm hais tias tus qauv qub tau hloov los ntawm European tus qauv, nws tus ntsuj plig thiab cov cai tseem ceeb tau nqa mus rau pem hauv ntej, ua lub npe "tseem ceeb} Cov khoom lag luam hlau loj hauv qhov kev lag luam rau hnub no.
