Hom H-Section Kem
H-section steel kem yog dav siv nyob rau hauv steel qauv tej yaam num. Raws li tus ntoo khaub lig-section variation thiab profile raws qhov siab, lawv poob rau hauv peb hom tseem ceeb: uniform-section H-kem, tapered H-kem thiab wedge-zoo li H-kem.
Txawm hais tias koj qhov phiaj xwm xav tau cov khoom sib xws - seem kab rau cov qauv kev ruaj ntseg lossis tapered / wedge-zoo li tus qauv tsim rau kev ua haujlwm zoo ntawm cov khoom siv loj hauv -span portals, peb pab neeg ua haujlwm engineering xyuas kom meej tias txhua qhov profile yog xam rau qhov siab tshaj plaws load- bearing kev ua tau zoo thiab kev ua haujlwm zoo.
Ntug -Zoo H-Kem

Daim ntawv thov: Sab & sab hauv kab ntawm lub teeb portal ncej steel vaj tse.
Tapered H-kem
Nta: Ob sab yog inclined ntug.
Qhov zoo: Optimized khoom layout raws li kev ntxhov siab faib. Lightens tus qauv thaum tuav lub peev xwm txaus.
Daim ntawv thov: Tapered kab rau lub teeb portal ntas.
Uniform-Section H-kum
Nta: Ob sab yog ntsug ntawm 90 degree.
Qhov zoo: Uniform load bearing thiab clear stress distribution. High standardization simplifies fabrication thiab ntawm -site installation.
Daim ntawv thov: Siv dav raws li qhov tsis tu ncua - qhov siab khoov kab hauv ntau -storey thav duab thiab kev cob qhia kev lag luam.
Cov txiaj ntsig tseem ceeb ntawm H-Section Kem
1. Cov cuab yeej cuab tam zoo heev
Cov flanges thiab lub vev xaib ntawm H- ntu steel kab ua haujlwm hauv kev sib koom ua ke, xa cov khoom muaj zog biaxial dabtsi yog khoov tsis kam, siab load peev thiab zoo torsion kuj. Nws load-cov kabmob muaj peev xwm ntawm ib chav tsev hnyav yog 15% siab dua li ntawm I-section steel kem.
2. Kev siv qhov chaw siab dua
Flange thickness tuaj yeem raug txo los ntawm 30% yam tsis muaj kev cuam tshuam rau lub zog. Preformed txheem qhov yooj yim installation pipeline. Lub vev xaib slim tsim txuag qhov chaw sib koom ua ke thiab ua kom thaj chaw siv tau zoo tshaj plaws.
3. Kev ua haujlwm nqa yooj yim
Nws yog 50% sib dua li cov pob zeb, txiav ntauwd crane lub sijhawm ua haujlwm los ntawm 40%.
4. Kev sib txuas yooj yim
Ua ntej-drilled bolt qhov yog tsim los rau siab precision, ua kom ceev ceev ntawm -qhov chaw sib dhos yam tsis muaj qhov vuam.
5. Lub Sijhawm Ua Haujlwm Txhim Kho
Kev tsim kho tuaj yeem ua tiav txawm tias huab cua zoo li cas. Kev ua haujlwm txuas ntxiv txawm tias nyob rau hnub los nag lossis daus, tsis tas yuav siv sijhawm kho.
Kev tsim khoom ntawm H-Section Kem
Kev tsim khoom ntawm peb H-section steel kem integrates advanced Tekla BIM nthuav dav nrog precision CNC cov ntaub ntawv npaj, automated los ua ke, thiab siab -lub zog Submerged Arc Vuam (SAW), ua raws li mechanical straightening thiab lwm yam kev sib koom ua ke, tag nrho nruj me ntsis xyuas los ntawm Non-Tuam Tshoj / 2. 2. thiab tau ntawv pov thawj los tiv thaiv- corrosive txheej los xyuas kom meej qhov siab tshaj plaws ntawm cov txheej txheem thiab kav ntev rau kev lag luam thoob ntiaj teb.
