Kev piav qhia luv luv

Smooth cylindrical CHS (lub voj voog hollow seem) steel kem nrog qhov tseeb -txiav puag ncig phaj thiab ntau daim duab peb sab welded gussets. Muab cov buckling tsis sib xws nyob rau hauv txhua qhov kev qhia - zoo tagnrho rau architectural exposed steel thiab industrial daim ntaub ntawv.

Cov lus piav qhia ntxaws

CHS no (lub voj voog hollow seem) round tubular kem yog tsim los ntawm kub - dov seamless los yog welded CHS steel rau EN 10210 / EN 10219 (S355J2H) los yog sib npaug GB / T 8162 (Q355B). Tsis zoo li H- kab teeb kab nrog sib txawv buckling tsis kam hais txog lawv qhov loj thiab me axes, CHS kem muaj tib lub vojvoog ntawm gyration nyob rau hauv tag nrho cov lus qhia - nws muab cov buckling tsis xws luag tsis hais txog kev thauj khoom, ua rau nws qhov zoo tshaj plaws structurally seem seem ib kilogram ntawm steel. Kem yog welded mus rau ib tug precision laser- txiav ncig puag ncig phaj, nrog ntau daim duab peb sab gusset daim hlau teem radially ntawm lub ncej ncej thiab puag phaj. Lub hauv paus phaj nta ua ntej-drilled bolt qhov (6+ pom los ntawm tus qauv saib lub kaum ntse ntse) nyob ib ncig ntawm lub perimeter rau thauj tog rau nkoj bolting. Nto tiav yog ib tug du matte grey primer (SA 2.5 txhaj tshuaj blasting + 60-80μm epoxy zinc{18}} nplua nuj primer), nrog kub -dip galvanizing muaj raws li kev xaiv. CHS kab ntawv tau nce ntxiv rau cov ntawv thov kev tsim vaj tsev - tshav dav hlau terminals, atrium cov qauv, cov chaw ua si, thiab chaw tos txais kev lag luam - qhov twg daim ntawv du, huv si cylindrical yog nyiam tshaj qhov kev lag luam zoo li H-sections. Rau kev siv hauv kev lag luam, CHS kab muaj qis qis qis coefficient (kwv yees li 0.5-0.7 vs 1.2-1.5 rau H-sections), txo qis cua lem ntawm cov qauv. Txhua kem yog dimensionally soj ntsuam rau txoj kab uas hla, phab ntsa thickness, puag phaj flatness, thiab tag nrho ncaj ncaj ua ntej tso.

Yam khoom

Cov ntsiab lus muag khoom

Uniform buckling resistance: CHS kem muaj zoo tib yam rx=ry (radius ntawm gyration), txhais tau tias nws resists buckling sib npaug nyob rau hauv tag nrho cov lus qhia - tsis muaj zog axis, tsis xav tau rau nruab nrab lateral bracing rau lub me axis

Architectural tiav zoo: Cov cylindrical du nto tsis muaj cov npoo ntse, tsis pom lub taub hau ntsia hlau, tsis muaj cov lus qhia flange - daim ntawv uas nyiam tshaj plaws rau cov hlau architectural uas pom qhov teeb meem

Cov cua qis qis: CHS kab muaj kwv yees li ib nrab ntawm cov cua cab coefficient ntawm H- ntu (Cd ≈ 0.6 vs 1.3), txo tag nrho cov cua ntsawj ntshab ntawm lub tsev los ntawm 10-15% nyob rau hauv kem-dense qauv

Radial gusset symmetry: Gussets yog nyob rau ntawm qhov sib npaug ntawm qhov sib npaug rau qhov sib npaug ntawm cov khoom thauj mus rau hauv lub hauv paus - qhov kev ntxhov siab ntawm txhua qhov gusset yog zoo tib yam, tshem tawm cov phaj tsis sib xws.

Kub- dov seamless los yog welded CHS: Peb tau los ntawm cov ntawv pov thawj mills (EN 10210 rau kub- tiav seamless; EN 10219 rau txias- tsim welded) thiab muab tag nrho cov ntawv pov thawj zeb nrog cov tshuaj muaj pes tsawg leeg thiab cov khoom siv tshuab

Tsis muaj kev xeb sab hauv: CHS kab yog kaw cov ntu - tsis zoo li qhib H- ntu nrog cov ntaub ntawv nthuav tawm, sab hauv ntawm CHS kem raug kaw los ntawm ib puag ncig, tshem tawm cov kev pheej hmoo corrosion sab hauv

Lub tuam txhab zoo

20+ xyoo muab CHS kab rau architectural thiab industrial tej yaam num nyob rau hauv 30+ lub teb chaws - peb to taub qhov nruj dua dimension thiab nto qhov yuav tsum tau ntawm cov hlau raug

Hauv -tsev vaj huam sib luag phaj txiav: Peb CNC plasma rotary txiav tshuab tsim cov phaj puag ncig nrog cov npoo du, tshem tawm qhov xav tau rau kev sib tsoo thib ob

Kev txhawb nqa engineering: Peb suav cov kab buckling tsis kam rau EC3 Tshooj 1-1 (kem buckling curves a lossis a0 rau CHS) thiab tsim lub hauv paus phaj-gusset system rau tag nrho axial + lub sijhawm thauj khoom ua ke

Cov lus hais nrawm: Muab cov kab qhov siab, txoj kab uas hla, phab ntsa thickness, thiab axial load - peb xa rov qab cov lus pom zoo nrog nqe kos thiab kev sib txuas tsim hauv 24 teev

Kev xa khoom thoob ntiaj teb: CHS kab zes ua haujlwm zoo hauv cov thawv ntim khoom (cov kab me me tuaj yeem muab tso rau hauv qhov loj dua rau ntau- xaj xaj loj, txo cov ntim khoom thauj)

Cov lus nug nquag

Q1: Dab tsi yog qhov zoo ntawm CHS kem ntawm H- kab teeb?

A: Peb qhov txiaj ntsig tseem ceeb: (1) Uniform buckling - CHS muaj lub zog zoo ib yam nyob rau hauv txhua qhov kev qhia, H-beams muaj zog npaum li cas ntawm lawv cov axis me. (2) Qhov tshwm sim - CHS yog qhov kev xaiv zoo tshaj plaws rau cov hlau tsis xeb hlau. (3) Cua - CHS muaj kwv yees li ib nrab ntawm cov cua rub ntawm H- ntu, txo cov loads sab nraud. Kev lag luam tawm -tawm yog tias CHS kev sib txuas (nqaj- rau-kem) yog qhov nyuaj kom nthuav dav dua li kev sib txuas rau H-beam flanges.

Q2: Koj puas tuaj yeem muab CHS txhua kab nrog cov xim pleev xim tsis yog galvanized?

A: Yog. Rau kev tsim vaj tsev, peb muab: (1) Txheem primer + topcoat xim system (epoxy intermediate + polyurethane topcoat) nyob rau hauv tej xim RAL. (2) Intumescent fireproof txheej rau hluav taws- ntsuas kab (30, 60, 90, lossis 120 feeb). (3) HDG + duplex xim rau kev sib xyaw ua ke thiab kev zoo nkauj. Kev npaj nto rau tag nrho cov tiav yog SA 2.5 moj tej tawg tu.

Q3: Yuav ua li cas koj txuas kab teeb rau ib puag ncig CHS kem?

A: CHS beam kev sib txuas yog qhov nyuaj dua li H-txoj kab sib txuas, tab sis peb txhawb txhua txoj hauv kev: (A) Welded fin plates - lub phaj ntsug yog khw-welded rau CHS kem ntsej muag, thiab beam bolts rau nws ntawm qhov chaw. (B) Los ntawm- daim hlau - ib lub phaj dhau los ntawm cov qhov nyob hauv CHS phab ntsa thiab yog welded ob sab. (C) Cov dab tshos/ntiv nplhaib sib dhos - bolted steel dab tshos clamps nyob ib ncig ntawm kab. Peb cov engineers yuav pom zoo rau txoj kev pom zoo raws li koj cov nqaj loads thiab architectural xav tau.

Q4: Dab tsi yog qhov siab tshaj plaws txoj kab uas hla CHS koj tuaj yeem tsim tau?

A: Peb tus qauv muaj peev xwm npog CHS txog 1200mm OD hauv cov khoom kub - dov. Rau txoj kab uas hla loj dua (txog 2000mm), peb tsim los ntawm dov - thiab -welded phaj - steel phaj yog dov rau hauv lub tog raj kheej, lub longitudinal seam yog SAW welded, thiab lub tog raj kheej yog welded rau lub hauv paus phaj. Cov no yog tsim los ntawm - nce CHS kab thiab muaj tib yam sab nraud zoo li seamless tab sis muaj kev lag luam ntau dua rau cov kab loj loj.
