2. Kev siv qhov chaw siab dua
Flange thickness tuaj yeem raug txo los ntawm 30% yam tsis muaj kev cuam tshuam cov qauv tsim. Preformed txheem qhov yooj yim installation pipeline. Lub vev xaib slim tsim txuag 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 khoom npaj, automated los ua ke, thiab siab -lub zog Submerged Arc Vuam (SAW), ua raws li mechanical straightening thiab lwm yam kev koom ua ke, tag nrho nruj me ntsis xyuas los ntawm Non-Tuam Tshoj . 2 kev xeem . thiab muaj ntawv pov thawj los tiv thaiv- corrosive txheej los xyuas kom meej qhov siab tshaj plaws ntawm cov qauv thiab ua haujlwm ntev rau cov haujlwm xa tawm thoob ntiaj teb.

FAQ:
Lub H- kab ke kho li cas rau lub hauv paus?
Kem zaum ntawm lub hauv paus pob zeb los ntawm lub hauv paus phaj cam khwb cia nrog thauj tog rau nkoj bolts; tom qab erection lub hauv paus yog grouted thiab cov txiv ntseej torque -tightened. Thauj tog rau nkoj-bolt layout, puag- phaj loj thiab qib txiv ntseej tuaj yeem muab rau hauv koj lub hauv paus kos duab.
Dab tsi verticality kam rau ua tiav, thiab cov kab ncaj nraim li cas?
Kem verticality yog kuaj los ntawm theodolite / qib tom qab tuav ib ntus; kev lag luam- ua raws li kev kam rau ua yog lean nyob rau hauv H/1000 thiab tsis ntau tshaj 25 mm rau storey- qhov siab kab, ces lub hauv paus yog grouted thiab finalised.
Welded H-section lossis kub-rolled H-beam - Kuv yuav xaiv daim ntawv li cas?
Kub- dov H-beams haum cov qauv ntu nrog ceev ceev thiab tus nqi qis; welded H-sections haum tsis yog- qauv qhov tob, tapered los yog wedge duab thiab hnyav flanges, thiab cia koj optimize seem rau lub sij hawm lub hnab ntawv. Ob leeg ua tau raws li qib zog tib yam.
Koj puas muab hluav taws kub thiab tiv thaiv corrosion rau kab?
Kev tiv thaiv corrosion yog los ntawm Sa 2.5 txhaj tshuaj blasting ntxiv rau epoxy zinc-nplua nuj primer nrog lub tsho tiv no, los yog kub-dip galvanizing rau sab nraum zoov siv; hluav taws kub kuj tuaj yeem ntsib nrog intumescent txheej los yog pob zeb encasement rau qhov yuav tsum tau hluav taws kub - lub sij hawm ntsuas.
Yuav ua li cas axial load, slenderness thiab thib ob - txiav txim los txiav txim?
Kem raug tshuaj xyuas rau axial compression, biaxial dabtsi yog khoov thiab buckling muaj peev xwm nyob rau hauv kev tswj hwm lean, thiab thib ob -kev txiav txim (P-delta) cuam tshuam los ntawm kab deflection suav nrog, raws li AISC 360 / EN 1993 / GB 50017, yog li cov seem nyob ruaj khov nyob rau hauv factored loads.
Puas yog splicing pob qij txha thiab cov ntsiab lus hauv paus?
Yog lawm. Khw lossis qhov chaw splices nrog splice daim hlau thiab siab - lub zog bolts, lub hauv paus phaj, lub hauv paus stiffeners thiab thauj tog rau nkoj- cov ntsiab lus bolt yog cov ncauj lus kom ntxaws hauv Tekla thiab muab, qhov loj me kom erection yooj yim thiab sib koom ua ke tsis tu ncua.
