1. Anatomy ntawm ib tug 358 laj kab vaj huam sib luag - Cov nqe lus koj yuav tsum paub
Ua ntej xaiv qhov tshwj xeeb, nws yuav pab kom nkag siabraws nraim qhov ua rau a358 laj kab. Kev tsim kho classic yog welded mesh vaj huam sib luag suav nrog:
Vertical daj kab hlau rhuav- ib leeg, txhav hlau hlau khiav saum toj mus rau hauv qab, spaced nruj nreem ntawm 12.7 hli (½ nti) chaw.
Ob chav kab rov tav kab- ob lub xov hlau khiav ib sab los ntawm txhua kab, sib tsoo cov pa taws ntawm txhua qhov kev sib tshuam. Cov no yog spaced 76.2 mm (3 nti) sib nrug vertically.
Mesh qhib- cov duab plaub ntawm kwv yees li 76.2 mm × 12.7 mm (li no lo lus "358").
Selvedge tiav- ntug kho nyob rau sab saum toj thiab hauv qab, feem ntau yog knuckled (looped) los yog sheared thiab welded mus rau ib tug nruj bar kom nruj ntxiv.
Qhov kev teeb tsa no tsim cov kab sib txuas uas muaj zog heev uas nyuaj heev rau kev nce siab (tsis muaj txhais tes lossis ntiv taw tuav), tiv taus cov ntsia liaj qhov rooj - txiav tawm (cov cuab yeej tsis tuaj yeem haum rau hauv 12.7 hli qhib kom tau txais txiaj ntsig), thiab pom pob tshab txaus rau kev soj ntsuam CCTV. Txawm li cas los xij, tsis yog tag nrho 358 vaj huam sib luag ua vaj huam sib luag. Kev ua tau zoo yog txiav txim siab los ntawm kev sib xyaw ua ke ntawmvaj huam sib luag qhov ntev, hlau ntsuas, thiab aperture kam rau ua- yog qhov hloov pauv uas peb tam sim no yuav taug kev.
2. Vaj Huam Sib Luag Qhov siab - Ntsuas qhov hem thawj, kev cai, thiab ib puag ncig
Xaiv qhov siab vaj huam sib luag qhov siab yog thawj zaug thiab pom kev txiav txim siab tshaj plaws. Txuj kev lag luam qhov siab li ntawm 1.8 m txog 3.6 m, thiab qee zaum dhau mus rau cov tub rog- qib ib puag ncig.
Common Vaj Huam Sib Luag Heights thiab Lawv Cov Ntawv Thov:
1.8 m (6 ft)- Siv rau qis-rau- nruab nrab kev pheej hmoo demarcation, xws li thaj chaw thaj chaw lossis thaj chaw muaj thaj tsam thaj tsam uas qhov kev hem thawj feem ntau yog kev ua txhaum cai es tsis yog txiav txim siab tawm tsam.
2.0 m - 2.4 m (6'6 "- 8 ft)- Lub workhorse range . 2.4 m high 358 fencing yog dav teev rau cov khoom lag luam, tsev kawm ntawv, cov chaw siv hluav taws xob, thiab cov chaw muag khoom. Ntawm qhov siab no, tus neeg tsis tuaj yeem ncav cuag saum toj kawg nkaus, tshwj xeeb tshaj yog thaum ua ke nrog lub cranked sab saum toj lossis barbed hlau overhang.
2.7 m - 3.0 m (9 - 10 ft)- Siab- daim ntawv thov kev nyab xeeb: cov chaw khaws ntaub ntawv, tsev loj cuj, tshav dav hlau, chaw tso roj, thiab chaw tsim hluav taws xob. Ntawm 3.0 m, lub laj kab ib leeg nthuav tawm qhov cuam tshuam lub cev muaj zog, ua rau lub sijhawm ncua sij hawm tiv thaiv kev nce toj txawm tias ua ntej ntxiv toppings.
3.3m-3.6m thiab siab dua- Kev ruaj ntseg ntawm ib puag ncig, feem ntau ua tau raws li cov qauv, qhov laj kab qhov siab ua rau tsis muaj kev tso cai nkag yuav luag tsis tuaj yeem tsis muaj cov cuab yeej tshwj xeeb. Cov haujlwm no feem ntau xav tau cov kev cai engineered posts thiab cov hauv paus tob.
Dab tsi yuav tsum xav txog thaum xaiv qhov siab:
Cov cai hauv tsev hauv zos tuaj yeem hais txog qhov siab tshaj plaws uas tso cai rau laj kab. Hauv qee qhov chaw rhiab heev, kev ntsuas kev nyab xeeb (xws li LPS 1175 lossis ASTM F2781) tswj hwm lub vaj huam sib luag qhov siab tsawg kawg nkaus ua ke nrog cov lus qhia tshwj xeeb thiab mesh. Pauleen ib txwm pom zoo rau qhov chaw soj ntsuam kom suav rau hauv av undulation - ib lub vaj huam sib luag 2.4 m ntawm txoj kab nqes yuav muaj qhov qis dua qhov siab ntawm nws sab siab yog tias tsis tau nqis los yog raked kom zoo. Raws li lub Hoobkas uas tsim cov qauv thiab qhov siab raws li qhov xav tau, peb tuaj yeem tsim cov kauj ruam thiab sib txawv - qhov siab qhov siab yam tsis muaj kev cuam tshuam mesh kev ncaj ncees.
3. Vaj Huam Sib Luag Dav thiab Post Centers - Feem ntau-Ntawm qhov txawv txav
Vaj huam sib luag dav feem ntau yog ntsuas nruab nrab ntawm cov chaw xa ntawv, txiav txim siab pes tsawg lub vaj huam sib luag thiab cov ntawv tshaj tawm koj qhov chaw yuav xav tau. Qhov dav dav tshaj plaws yog2.0m, 2.2m, thiab 2.5m, txawm tias kev cai dav txog li 3.0 m yog ua tiav nrog txoj cai engineering.
Lub vaj huam sib luag dav cuam tshuam li cas rau kev ruaj ntseg thiab kev teeb tsa:
Cov vaj huam sib luag (2.0 m - 2.2 m):Stiffer los ntawm qhov xwm txheej, ua rau lawv tiv taus ntau dua rau kev sim thiab txo qis deflection nyob rau hauv cua load. Lawv xav tau ntau cov ntawv tshaj tawm hauv ib mais, nce lub hauv paus thiab tus nqi xa tawm tab sis xa cov denser, nyuaj dua - rau - ua txhaum kab. Qhov kev teeb tsa no yog qhov nyiam rau siab - tsev loj cuj thiab embassies.
Dav dav (2.5 m):Kev lag luam ntau dua rau ib kab 'meter' vim tias tsawg dua posts thiab fixings xav tau. Lawv tau txais kev pom zoo rau nruab nrab- qhov chaw nyab xeeb uas muab cov kab uas hla ntawm cov xaim thiab cov ncej ncej yog nce raws li kev tiv thaiv sagging.
Ib qho yuam kev tseem ceeb uas peb tau pom ntau xyoo dhau los yog qhia txog lub vaj huam sib luag dav nrog lub ntsuas hluav taws xob nyias thiab cov ntawv qis dua - qhov tshwm sim yog lub laj kab uas tuaj yeem khoov qhib tau yooj yim. Ntawm Pauleen, peb ib txwm suav covlub sij hawm ntawm inertiatxheeb ze rau qhov kawg thiab nruab nrab tom qab sib nrug thaum qhia cov neeg siv khoom. Raws li txoj cai ntawm tus ntiv tes xoo, yog tias koj xaiv rau lub vaj huam sib luag dav 2.5 m, koj txoj kab uas hla ntawm txoj kab uas hla yuav tsum yog tsawg kawg yog 4.76 hli, thiab koj cov ncej yuav tsum tsis pub tsawg dua 80 hli × 80 hli × 3 hli SHS (Square Hollow Section). Rau 2.0 m dav, 60 hli × 60 hli ncej nrog 4 hli daj tuaj yeem txaus rau kev siv lag luam. Peb muab tag nrho cov txheej txheem xam raws li qhov kev thov.
4. Wire Gauge - Qhov Ntsuas Qhov Tseeb Ntawm Kev Tawm Tsam Tawm Tsam
Hlau gauge (qhia hauv metric txoj kab uas hla los yog SWG) yog arguably qhov tseem ceeb tshaj technical parameter tom qab vaj huam sib luag loj. Nws cuam tshuam ncaj qha rau lub sijhawm ncua sijhawm tiv thaiv kev siv cov cuab yeej txiav, lub vaj huam sib luag tiv thaiv kev nce toj, thiab ntev - lub sij hawm seem stability.
Common wire diameters nyob rau hauv 358 fencing:
Pale (verttical) hlau diameters:3.0 hli, 3.55 hli, 4.0 hli, 4.76 hli (3/16 "), 5.0 hli, thiab mus txog 6.0 hli rau kev siv heev.
Kab rov tav hlau diameters:Feem ntau yog ob lub xov hlau. Kev sib xyaw ua ke: 4.0 hli + 4.0 hli, 4.76 hli + 4.76 hli, 5.0 hli + 5.0 hli. Hauv qee qhov hnyav - lub luag haujlwm vaj huam sib luag, cov kab kab rov tav tuaj yeem ua tuab dua li cov vertials, piv txwv li, ntxaib 6.0 hli kab rov tav nrog 5.0 hli daj ntseg, tiv thaiv kev sib kis thiab ramming.
Yuav txhais li cas thiab xaiv qhov ntsuas qhov tseeb:
Kev lag luam yooj yim (4 hli daj ntseg / 4 hli ob kab rov tav):Muab suab qeeb tawm tsam kev tawm tsam thiab tsim nyog rau cov vaj tse uas muaj kev tiv thaiv. Kuaj kom tiv taus lub bolt cropper nrog kev siv zog me ntsis rau lub sijhawm txwv. Txawm li cas los xij, nws tsis ua raws li ntau cov qauv kev ruaj ntseg uas tau lees paub rau kev tawm tsam tsis tu ncua.
Txhim khu kev ruaj ntseg (4.76 hli daj ntseg / 4.76 hli ob kab rov tav):Qhov no tau dhau los ua lub hauv paus rau LPS 1175 SR1 thiab cov chav kawm sib npaug. Cov hlau hla ntau ntxiv - ntu ntu ua rau lub zog yuav tsum tau txiav los ntawm ntau cov xov hlau. Ntau ntawm peb cov neeg siv khoom hauv cov ntaub ntawv qhia qhov no yog qhov tsawg kawg nkaus, feem ntau ua ke nrog cov hmoov txheej txheej kub -dip galvanizing.
Kev ruaj ntseg siab (5.0 hli daj ntseg / 5.0 hli ob kab rov tav):Haum rau LPS 1175 SR2 thiab ncua kev nres nres. Lub vaj huam sib luag ua hnyav hnyav, yuav tsum tau muaj zog tom qab lub hauv paus. Ntawm qhov ntsuas no, txawm tias 2-feeb kev tawm tsam nrog lub hacksaw lossis 36-nti bolt cropper ua nyuaj heev.
Kev ruaj ntseg siab tshaj plaws (5.0 hli pale nrog 6.0 hli kab rov tav los yog ntau dua):Rau lub tsev loj cuj perimeters, tub rog puag, thiab nuclear chaw. Lub laj kab yog zoo welded steel grating. Pauleen tau tsim cov vaj huam sib luag bespoke nrog 6.35 hli (¼ nti) ntsug xov hlau thiab ntxaib 8 hli kab rov tav, welded ntawm txhua qhov kev sib tshuam thiab ncej-galvanized rau kev tiv thaiv corrosion nyob rau lub neej.
Daim ntawv ceeb toom ntawm cov khoom zoo thiab vuam:Txawm tias txoj kab uas hla tsis raug yog tias cov hlau tsis tshua muaj - carbon lossis tsis zoo welded. Peb tsuas yog siv siab -tensile steel hlau nrog lub zog tensile yam tsawg kawg nkaus ntawm 550 MPa. Txhua qhov kev sib tshuam yog ib txhij siv hluav taws xob fused siv automated multi- taw tes vuam tshuab, thiab peb tus ntoo khaub lig-weld shear zog raug kuaj kom tshaj 75% ntawm cov hlau qhov kawg ntawm lub zog - zoo tshaj qhov kev lag luam pib. Qhov no ua kom ntseeg tau tias tus neeg tawm tsam tsis tuaj yeem tsuas "pop" welds ntawm sab - mus rau - sab ua haujlwm.
5. Mesh Qhib - Kev Tiv Thaiv -Climb thiab Anti-Cut Foundation
Lub cim tseem ceeb ntawm 358 laj kab nyob hauv nws qhov aperture:76.2 hli × 12.7 hli (3 "× ½"). Qhov no tsis yog qhov loj me me - nws tau tsim tshwj xeeb los kov yeej tib neeg tes thiab cov cuab yeej txiav.
Vim li cas qhov 12.7 hli ntsug qhov sib txawv tseem ceeb:
Qhov sib txawv 12.7 mm yog nqaim dhau rau tus neeg laus ntiv tes txhawm rau txhawm rau thiab me me dhau rau khau ntiv taw- tuav. Txawm tias ib rab riam me me los yog lub hau ntswj tsis tuaj yeem muab ntxig thiab sib tw kom zoo rau cov xov hlau sib nrug. Qhov no yog thawj qhov kev tiv thaiv -nce khoom. Thaum sim nce siab, tus neeg ua phem tsis tuaj yeem ua tiav kev yuav khoom, yuam kom lawv tso siab rau tus ntiv taw muaj zog tab sis tsis ruaj khov - cov txheej txheem jamming uas yooj yim cuam tshuam.
76.2mm kab rov tav sib nrug:
Qhov sib nrug no tso cai rau pom qhov tsim nyog los ntawm lub vaj huam sib luag rau kev saib xyuas ntuj thiab CCTV thaum me me dhau los nyem lub cev los ntawm (tus me nyuam muaj kev pheej hmoo ib sab) thiab nruj dhau los ntxig cov txheej txheem hydraulic kis yam tsis tau txiav thawj qhov nkag. Ua ke nrog ob txoj kab rov tav, txhua qhov kev sim thawb lub mesh horizontally yog tawm tsam los ntawm cov txheej txheem sib tshooj.
Aperture kam rau ua thiab nws qhov cuam tshuam kev ruaj ntseg:
Ib lub laj kab uas ntsuas 13.5 hli es tsis txhob 12.7 hli vim qhov kev tsim khoom tsis zoo yuav tsis muab cov ntiv tes zoo ntxiv lawm - cov lus tsis lees paub. Ntawm Pauleen, peb cov mesh qhib yog tswj kom nruj kam rau ua ntawm ± 0.3 hli rau qhov sib nrug ntawm qhov daj ntseg, txheeb xyuas tsis tu ncua ntawm cov kab ntau lawm siv laser ntsuas. Peb kuj muabsub-12.7 mm qhibrau kev txiav siab heev-thiab- ncav tsis cuag; Piv txwv li, ib qho 9.5 hli ntsug daj qhov sib txuas ua ke nrog 50 hli kab rov tav qhov sib txuas xa cov "me me 358" mesh siv los tiv thaiv -kev cuam tshuam glazing kev tiv thaiv hauv siab - cov rooj vag txaus ntshai.
Custom aperture xaiv:
Thaum tus qauv 358 mesh npog 90% ntawm cov lus qhia tshwj xeeb, qee qhov haujlwm xav tau hloov pauv hloov pauv rau cov kev hem thawj tshwj xeeb:
76.2 hli × 9.5 hli- Kev tiv thaiv ntiv tes ntxiv, feem ntau siv nyob ib sab ntawm thaj chaw pej xeem uas muaj menyuam yaus tuaj.
50mm × 12.7 hli- Kev nruj dua, txo qhov pom kev tab sis cov khoom siv ntxiv, siv rau kev sib tsoo deflector fencing lossis hauv cov ntawv thov xav tau cov ntsaum zoo heev - txiav cov khoom.
76.2 hli × 15.8 hli- Tsis tshua muaj, siv tsuas yog qhov kev cai tso cai qhib me ntsis rau cov tsiaj qus txoj hauv kev thaum tuav ib qho kev thaiv. Peb qhia tawm tsam qhov no tshwj tsis yog tias koj paub tseeb tias qhov kev pheej hmoo profile tso cai rau nws.
Txhua qhov kev cai mesh qhib peb tsim yog raug rau tib qhov kev ntsuam xyuas nruj nruj.
6. System Compatibility: Posts, Fixings, thiab Accessories
Xaiv lub vaj huam sib luag yog tsuas yog ib nrab ntawm kev sib ntaus sib tua. Lub mesh yuav tsum integrate nrog ib tug zoo me me ncej system. Tus qauv ncej rau 358 laj kab yog ib qho square lossis square hollow seem (SHS / RHS) tsim los ntawm cov hlau galvanized, feem ntau nrog lub hauv paus phaj rau plinth mounting los yog tsim rau cov tub ntxhais drilling thiab grouting rau hauv paus.
Cov ntsiab lus tseem ceeb:
Tshooj loj:60 × 60 mm, 80 × 80 mm, 100 × 100 mm, qee zaus 120 × 120 mm. Cov kev xaiv yuav tsum phim lub vaj huam sib luag qhov siab thiab xav tau cua / daus.
Phab ntsa thickness:Feem ntau 3.0 mm, 4.0 mm, lossis 5.0 mm. Rau txhua yam saum toj no 2.4 m vaj huam sib luag qhov siab, peb pom zoo kom tsawg kawg ntawm 4.0 hli phab ntsa.
Anti -tamper clamps:Pauleen siv kub-dip galvanized cam khwb cia los yog nias clamps haum nrog shear-tawm cov txiv ntseej uas tawm hauv qhov du, tsis yog- lub khob hliav qab tshem tau ib zaug nruj. Qhov no tiv thaiv disassembly ntawm lub vaj huam sib luag los ntawm tus ncej.
Yog tias koj xaiv qhov hnyav - ntsuas 5 hli vaj huam sib luag tab sis ua ke nrog lub teeb 60 × 60 × 3 mm ncej, qhov tsis muaj zog taw tes hloov mus rau tus ncej nws tus kheej - tus neeg paub txog kev tawm tsam tuaj yeem tawm tsam lub hauv paus lossis clamp. Peb yuav nco ntsoov pom zoo ib qho kev sib tw. Raws li lub Hoobkas, peb muab ua tiav 358 laj kab tshuab, suav nrog kaum cov ncej, rooj vag thav duab, thiab hluav taws xob laj kab kev sib txuas, txhua tus tsim kho rau koj lub vaj huam sib luag spec.
7. Coatings and Longevity - Tsis txhob saib ib puag ncig
Txawm hais tias phau ntawv qhia no tsom rau qhov loj me thiab ntsuas, kev tiv thaiv corrosion tsis tuaj yeem sib cais los ntawm cov kev xaiv no vim tias cov kab hlau hlaws tsis nyob ntev yog xeb txo tus ntoo khaub lig-section. Peb feem ntau muaj peb theem tiav:
Kub-dip galvanized rau EN ISO 1461- Qhov nruab nrab txheej txheej tsawg kawg nkaus ntawm 55 microns rau cov xov hlau loj dua lossis sib npaug li 4 hli, ua kom 25+ xyoo nyob rau hauv qhov chaw nyob deb nroog.
Galvanized + polyester hmoov txheej- Ntxiv txheej (60–80 microns yam tsawg kawg nkaus) nyob rau hauv ib qho xim RAL, sib txuas cov zinc tiv thaiv kev ua kom zoo nkauj. Qhov tseem ceeb rau marine lossis siab - thaj chaw av noo.
