Dab tsi yog Lattice Steel Kab?
Lub lattice steel kem yog ntsug load-cov tswv cuab muaj ob lossis ntau lub ntsiab chords txuas nrog lacing tuav, batten daim hlau los yog ob qho tib si ua ke, tsim ib qho qhib -web truss kem. Cov chords feem ntau yog cov ces kaum, H- ntu lossis ntu ntu, thaum cov tswv cuab hauv lub vev xaib hloov cov quab yuam ntawm cov chords kom lub rooj sib txoos coj ua ib kem monolithic. Vim hais tias cov khoom yog kis tawm ntawm lub centroid, kem nce lub vojvoog loj ntawm gyration thiab siab tiv thaiv buckling nrog cov hlau tsis tshua muaj zog dua li cov khoom -web kem ntawm tib lub peev xwm. Cov kab lattice feem ntau muaj nyob rau hauv cov tsev lag luam hnyav, crane- txhawb nqa cov qauv, cov kav xa hluav taws xob thiab lub hauv paus sib sib zog nqus shoring systems.
Main Hom Lattice Steel Kab
| Hom | Kev tsim kho | Tej daim ntawv thov |
|---|---|---|
| Lub kaum sab xis latticed | Lub kaum sab xis, H- ntu lossis HSS chords txuas nrog lub vev xaib lacings lossis battens, bolted lossis welded | Heavy industrial nroj tsuag, crane runway structures, tus kheej - txhawb nqa, ib ntus shoring huab tais posts |
| CHS latticed kab | Circular hollow seem chords thiab bracing welded los yog mechanically koom rau hauv truss ncej | Cua yees, tshaj tawm cov masts, telecom pylons, cov qauv raug cua siab loads |
| H-section latticed kab | Rolled los yog welded H-section chords nrog phaj lacings lossis battens | Hnyav load-cov kabmob nyob rau hauv ntev-span nroj tsuag, khoom siv platforms, multi-storey industrial tsev |
Vim li cas cov kab lattice siv nyob rau hauv Hnyav Industrial Buildings
Lub zog-rau- qhov hnyav piv: qhib- lub vev xaib truss teeb tsa ua tiav lub sijhawm siab ntawm inertia nrog cov hlau tsawg, txo qis tus kheej- hnyav thiab, dhau los, lub hauv paus loads.
Lateral load tsis kam: lub truss system hloov cua thiab seismic zog zoo los ntawm chords thiab cov tswv cuab hauv lub vev xaib, thaum daim phiaj qhib nthuav tawm me me rau cua.
Kev siv qhov chaw: sab hauv ntawm cov ncej ncej tuaj yeem nqa cov kav dej, kev tu ntaiv lossis kev pabcuam pabcuam, thiab kev sib txuas ntawm cov ncej sib txuas tuaj yeem ua rau kom pom tseeb -span peev ntawm lub tsev ncej.
Customization: ob-, peb- lossis plaub- ceg kev teeb tsa tuaj yeem tsim kho kom haum rau qhov tshwj xeeb nruj, lub zog thiab kev tsim vaj tsev, thiab cov tswv cuab geometry tuaj yeem hloov kho los ntawm kev sib txawv ntawm cov txheej txheem lacing.
Lattice Column vs H-Kem for Workshop Frames
| Feature | H-Kab | Lattice Kem |
|---|---|---|
| Hla -section | Ib leeg khoom-web profile | Qhib -web system ntawm chords thiab lacings |
| Fabrication nqi | Automated ntau lawm, qis zog tswv yim | Kev cai txiav, vuam thiab haum, ntau dua kev siv zog |
| Load cwj pwm | axial muaj peev xwm zoo heev thiab muaj zog -axis dabtsi yog khoov | Superior lateral stiffness nyob rau hauv siab, slender daim ntaub ntawv |
| Kev teeb tsa | Ceev ceev, thauj thiab erection | Ntau lub ntim ntim, thauj thiab chaw sib dhos |
| Kev tiv thaiv corrosion | Yooj yim rau tawg, pleev xim thiab tshuaj xyuas | Sab hauv ntawm lub vev xaib yog qhov nyuaj rau nkag mus |
| Qhov zoo tshaj plaws siv rau | Standard warehouses, qis rau nruab nrab qhov siab rhiav | Ntev ntev -span tsev, hnyav crane loads, tsis muaj zog lub hauv paus tej yam kev mob |
Hauv kev xyaum, H-kem feem ntau yog thawj qhov kev xaiv rau tus qauv- qhov siab qhov chaw ua haujlwm qhov ceev thiab tus nqi zog ua haujlwm. Cov kab lattice ua kom txaus nyiam thaum crane muaj peev xwm siab, lub hauv paus bearing muaj peev xwm raug txwv, los yog txo cov qauv steel tonnage yog tus tsav tsheb tseem ceeb.
Tsim, Fabrication thiab Quality Control
Cov kab lattice rau cov tsev lag luam yog tsim los rau lub teb chaws lossis thoob ntiaj teb cov qauv steel qauv xws li GB 50017, EN 1993-1-1 (Eurocode 3) lossis AISC 360, nyob ntawm seb qhov project qhov chaw. Fabrication ua raws li EN 1090-2 chav kawm ua tiav lossis cov kev cai hauv cheeb tsam sib xws, nrog rau kev vuam ua tiav los ntawm cov kws tshaj lij uas tau lees paub rau AWS D1.1 lossis EN ISO 9606 kev tsim nyog. Cov welds tseem ceeb ntawm chords thiab cov tswv cuab hauv lub vev xaib raug txheeb xyuas los ntawm tsis yog - kev kuaj kev puas tsuaj xws li kev sim ultrasonic lossis kev ntsuas cov khoom sib nqus, thiab cov kab ntau ntau ceg tuaj yeem ua khw ua ntej los kuaj xyuas qhov ntev ua ntej xa. Kev sib txuas rau txhua kab thiab kab teeb feem ntau yog ua nrog lub zog muaj zog bolts, uas yooj yim rau kev txhim kho thiab kev soj ntsuam.
Kev tiv thaiv corrosion yog xaiv rau cov nroj tsuag huab cua: tua blasting rau Sa 2.5 ua raws li zinc-nplua nuj primer thiab polyurethane topcoat rau aggressive chemical los yog smelting ib puag ncig, los yog kub-dip galvanizing rau ISO 1461 qhov twg ntev txij nkawm- lub neej dawb yog yuav tsum tau.
Complementary Cheebtsam rau ua kom tiav Rhiav Ncej
Heavy-cov haujlwm crane girders thiab ntev-span ru tsev trusses, uas txuas rau cov kab lattice thiab xa crane thiab ru tsev loads rau hauv kem system.
Txias- tsim C thiab Z purlins rau lub ru tsev thiab phab ntsa cladding, nrog kub -dip galvanized los yog Galvalume tiv thaiv.
Bracing systems suav nrog hla kem bracing, nruj khi kab teeb thiab gusset daim hlau txhawm rau xauv txhua kab rau hauv qhov ruaj khov peb- qhov ntev.
Siab- lub zog bolts, suav nrog Qib 10.9 kev sib txhuam- tuav bolts thiab thauj tog rau nkoj bolt pawg, rau kem - mus rau - lub hauv paus thiab kem - mus rau -Kum kev sib txuas hauv qab qaug zog loading.
Cov lus nug nquag
Vim li cas thiaj xaiv ib kab lattice hla ib kab hlau khov?Lub moj khaum qhib kis cov hlau deb ntawm lub centroid, ua rau lub vojvoog ntawm gyration thiab buckling tsis kam thaum txo cov khoom siv. Nws yog qhov hnyav -kev daws teeb meem rau cov kab siab thiab cov khoom hnyav.
Cov kab lattice txuas thiab tiv thaiv li cas?Chords thiab cov tswv cuab hauv lub vev xaib tau koom nrog kev sib txuas los yog bolting. Sab nraum zoov thiab kev lag luam kab feem ntau yog tiv thaiv los ntawm kub-dip galvanizing lossis hnyav-cov dej num epoxy txheej txheej xaiv rau qhov chaw huab cua.
Cov kab lattice tau tsim thiab tsim li cas?Tsim raws li cov qauv steel qauv xws li GB 50017, EN 1993-1-1 lossis AISC 360. Cov tswvcuab tau ua tiav hauv lub khw nrog CNC txiav thiab automated vuam, tom qab ntawd sib sau ua ke ntawm qhov chaw nrog lub zog siab.
Cov kab lattice puas kim dua H-kem?Fabrication zog ib tonne feem ntau yog siab dua vim yog kev cai txiav, vuam thiab haum. Txawm li cas los xij, qhov txo qis steel tonnage thiab cov hauv paus me me tuaj yeem txo tus nqi tag nrho rau cov qauv siab lossis hnyav hnyav.
Cov kab lattice puas tuaj yeem txhawb nqa nyiaj siv ua haujlwm cranes?Yog lawm. Cov kab lattice feem ntau siv rau hauv crane-txhawb nqa, qhov twg crane girders thiab bracing systems tau txuas nrog rau kem kom tiv thaiv cov khoom hnyav thiab kev sib tsoo ntawm cov cranes mus ncig.
Cov qib steel dab tsi yog siv rau cov kab lattice?Cov qib feem ntau yog Q235B thiab Q355B txog GB/T 1591, S235JR thiab S355JR/J0/J2 rau EN 10025-2, thiab ASTM A36 lossis A572 Qib 50. Kev xaiv qib ua raws li cov tswv cuab lub zog, tuab thiab qhov project specification.
