Kev piav qhia luv luv

Kub-dip galvanized SHS (square hollow seem) kem kem nrog hnyav-duty square puag phaj thiab dual- sab gusset reinforcement. Kev sib npaug sib npaug ntawm ob qho tib si lub hauv paus axes ua rau qhov no yog qhov kev xaiv zoo tshaj plaws rau kaum kab thiab biaxial loading tej yam kev mob.

Cov lus piav qhia ntxaws

Lub thawv ntawv galvanized no yog tsim los ntawm kub- dov SHS (square hollow seem) cov qauv steel - kaw cov duab plaub nrog qhov dav thiab qhov tob. Ntu SHS muab qhov sib npaug ntawm seem modulus (Sx=Sy) thiab sib npaug ntawm lub vojvoog ntawm gyration (rx=ry) txog ob lub ntsiab axes, ua rau nws yog qhov zoo tshaj plaws kem xaiv rau cov qauv uas thauj khoom tuaj yeem los ntawm ob qho kev taw qhia: kaum kab, ncej kab hauv ob qho tib si orthogonal cov lus qhia, thiab txhua kab txhawb nqa crane longitudinal loading beams. Cov kem yog welded mus rau lub square puag phaj, thiab kem - hauv paus hlws ris yog ntxiv nrog gusset daim hlau: ib tug loj daim duab peb sab gusset rau txhua sab lub ntsej muag thiab ntxaib -rib gussets rau pem hauv ntej lub ntsej muag, muab multi-directional moments hloov mus rau hauv lub hauv paus. Lub hauv paus phaj muaj 4 pre-drilled thauj tog rau nkoj bolt qhov ntawm cov ces kaum. Kev sib dhos ua tiav tau dhau los ua kub-dip galvanizing rau ISO 1461 (70-100μm), nrog rau cov yam ntxwv spangle tiav muab kev tiv thaiv corrosion tag nrho rau txhua qhov chaw sab nraud thiab - ntawm qhov cua qhov - cov kab noj hniav sab hauv. Cov kab ke hauv lub thawv muaj qhov huv, niaj hnub pom zoo rau ob qho tib si kev lag luam thiab kev siv vaj tse. Welds raug coj mus rau AWS D1.1 nrog UT/MT tshuaj xyuas. Txhua kem yog ntsuas rau lub hauv paus phaj flatness (± 1mm ​​/ m), kab ncaj nraim (L / 1000), thiab ntsia liaj qhov rooj qhov chaw (± 1mm) ua ntej xa khoom.

Yam khoom

Cov ntsiab lus muag khoom

Biaxial dabtsi yog khoov tsis kam: SHS kem kab muaj qhov zoo tib yam seem modulus nyob rau hauv ob qho tib si cov lus qhia - qhov tseem ceeb rau kaum kab thiab lub caij thav ntawv qhov twg cua / seismic loading alternates kev taw qhia

Ntxaib-rib pem hauv ntej gussets muab ob npaug rau qhov ntev ntawm qhov txuas ntawm lub ntsej muag tseem ceeb - qhov twg lub sijhawm khoov los ntawm cov kab hluav taws xob siab tshaj plaws yog siab tshaj - yam tsis tau nce lub hauv paus taw taw

Kaw seem=tsis muaj qhov chaw sab hauv: Tsis zoo li H- kab teeb kab uas lub vev xaib sab hauv pom thiab nkag mus tsis tau rau kev pleev xim, SHS sab hauv raug kaw - HDG tiv thaiv txuas mus rau sab hauv kab noj hniav ntawm lub qhov cua

Torsional stiffness kom zoo: SHS seem muaj ntau dua torsional tas li (J) dua li qhib H-sections - tseem ceeb rau txhua kab uas txhawb nqa eccentric loads lossis crane khiav kab teeb nrog rau sab surge rog

Galvanized spangle pov thawj: Txhua kem txheej txheej tuab yog ntsuas ntawm 5 ntsiab lus ntawm ib lub ntsej muag nrog lub ntsuas hluav taws xob, thiab cov qauv spangle yog qhov pom kev ntsuas rau qhov sib xws - sau tseg hauv daim ntawv tshuaj ntsuam txheej

Architecturally huv si: Lub ntsej muag tiaj tus ntawm lub thawv kem lees txais kev ua tiav (cladding, signage, teeb pom kev zoo mounts) yam tsis muaj geometry ntawm flange cov lus qhia thiab web recesses

Lub tuam txhab zoo

Tus kws tshaj lij kab kem: Peb tsim ntau SHS / RHS txhua xyoo ntau dua li lwm yam kab ke - peb cov jigs tau ua kom zoo rau cov seem square, xa rov qab sai dua thiab qis dua tus nqi tsim khoom.

Hauv -lub tsev HDG: Peb 12.5m galvanizing da dej tuav cov kab kem mus txog 12m hauv ib qho poob - tsis muaj qhov sib txuas-dipping, tsis muaj qhov sib tshooj

Kev sib txuas engineering: Peb pab neeg tsim txhua qhov kev sib txuas bolted rau lub thawv kem - beam kawg daim hlau, fin plates, cap plates, thiab bracing gussets - nrog rau cov kev sib tw tshwj xeeb ntawm kev txuas mus rau seem kaw (tsis muaj kev nkag sab hauv) hais hauv kev tsim

Kev ruaj ntseg zoo: Txhua lub hauv paus phaj flatness yog kuaj nrog tus kws kho tshuab qhov ncaj; txhua txoj haujlwm ntawm lub qhov ntsia hlau raug txheeb xyuas nrog qhov mus / tsis muaj - mus ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas

Kev tswj hwm qhov project: Tus neeg saib xyuas qhov project tshwj xeeb muab cov kev hloov kho tshiab txhua lub lim tiam nrog cov duab hauv khw - koj paub tseeb tias koj cov kab nyob qhov twg hauv kev tsim khoom txhua lub sijhawm

Cov lus nug nquag

Q1: Dab tsi yog qhov txawv ntawm SHS kem kem thiab H- kab teeb?

A: SHS (square hollow section) and H-beam columns differ in three main ways: (1) Biaxial strength - SHS has equal bending resistance in both directions (Sx = Sy), H-beams have a strong and weak axis (Sx >>Sib). (2) Torsion - SHS muaj 50-100 × siab torsional nruj dua H-beams, tseem ceeb rau eccentric loads. (3) Kev sib txuas - bolting beams rau SHS yuav tsum tau los ntawm -bolts los yog welded fin daim hlau (tsis muaj cov txiv ntseej sab hauv), thaum H-beams tso cai yooj yim bolted txuas rau flanges. Peb yuav pab koj xaiv hom kab zoo raws li koj qhov kev teeb tsa.

Q2: Vim li cas kem no muaj qhov sib txawv gusset configurations ntawm txawv ntsej muag?

A: Lub ntsej muag sab (sab laug thiab sab xis hauv daim duab) muaj ib qho loj gussets - cov ntsej muag no feem ntau txuas mus rau lub tsev lub thav duab ntev uas khoov qis dua. Lub ntsej muag pem hauv ntej muaj ntxaib -rib gussets - qhov no feem ntau yog qhov kev taw qhia ntawm txoj kab uas hla lub hauv caug sib koom ua ke siv lub sijhawm khoov siab tshaj plaws rau sab. Lub gusset configuration yog tsim tshwj xeeb rau koj lub tsev txoj kev thauj khoom, tsis yog tus qauv qauv.

Q3: Koj puas tuaj yeem txuas cov kab txuas txuas rau lub thawv kem hauv khw?

A: Yog lawm - peb tuaj yeem yuav khoom-weld kawg phaj stubs, fin plates, cap plates, thiab stiffener daim hlau rau hauv kem kem ua ntej galvanizing. Qhov no yog qhov zoo tshaj plaws: cov ntawv sib txuas yog welded nyob rau hauv kev tswj kav khw, tshuaj xyuas, thiab tom qab ntawd galvanized ua ke nrog kem, yog li tag nrho cov sib dhos (kem + kev sib txuas) raug tiv thaiv ib zaug. Cov neeg ua haujlwm hauv lub vev xaib tsuas yog bolt cov kab teeb rau ua ntej -welded daim hlau - tsis muaj welding rau sab.

Q4: Koj ua li cas tiv thaiv lub thawv kem los ntawm distorting thaum lub sij hawm galvanizing?

A: SHS kab yog kaw cov seem uas tuaj yeem ntxiab cua thiab nthuav dav thaum lub sijhawm HDG raus yog tias tsis muaj qhov cua zoo. Peb laum qhov qhov (feem ntau yog 10-12mm txoj kab uas hla) ntawm ob qho kawg ntawm txhua kab - nyob ze ntawm lub kaus mom sab saum toj thiab ze ntawm lub hauv paus phaj - nyob qhov twg lawv muab zais tom qab kev teeb tsa lossis tuaj yeem ntsaws. Lub qhov tso cai rau zinc ntws mus rau hauv cov kab noj hniav thiab cov huab cua kom khiav tawm, tiv thaiv kev tsim cov siab uas tuaj yeem cuam tshuam cov phab ntsa. Qhov no yog qhov yuav tsum tau ua hauv peb cov txheej txheem HDG, tsis yog kev xaiv ntxiv.
