Xov xwm - Steel Structure: Ib Qhov Txheej Txheem Tseem Ceeb hauv Kev Tsim Kho Niaj Hnub No

Nyob rau hauv niaj hnub architecture, tsheb thauj mus los, kev lag luam, thiab hluav taws xob engineering,steel qauv, nrog nws ob qhov zoo hauv cov khoom siv thiab cov qauv, tau dhau los ua lub zog tseem ceeb tsav kev tsim kho tshiab hauv engineering technology. Siv cov hlau ua nws cov khoom siv thauj khoom tseem ceeb, nws hla cov kev txwv ntawm cov qauv tsim los ntawm kev tsim khoom thiab kev teeb tsa modular, muab cov kev daws teeb meem zoo rau ntau txoj haujlwm nyuaj.

Qhov zoo thiab qhov tsis zoo ntawm Cov Qauv Hlau - CHINA ROYAL STEEL

Kev txhais thiab xwm ntawm Steel Structure
Steel qauv hais txog lub load-bearing structural system muaj li ntawmhlau daim hlau, steel seem (H kab teeb, Ua channels, lub kaum sab xis steel, thiab lwm yam), thiab cov kav hlau steel, ruaj ntseg los ntawm vuam, lub zog siab bolts, lossis rivets. Nws cov ntsiab lus yog siv zog steel lub zog siab thiab toughness kom sib npaug ntawm cov loads ntsug (tuag hnyav thiab cov khoom hnyav) thiab kab rov tav loads (cua thiab av qeeg) los ntawm lub tsev lossis qhov project mus rau nws lub hauv paus, ua kom muaj kev ruaj ntseg. Piv nrog rau cov qauv pob zeb, cov ntsiab lus zoo ntawm cov qauv hlau nyob hauv lawv cov khoom siv kho tshuab: lawv lub zog tensile tuaj yeem ncav cuag 345 MPa, ntau dua 10 npaug ntawm cov pob zeb zoo tib yam; thiab lawv cov plasticity zoo heev tso cai rau lawv deform nyob rau hauv load yam tsis muaj kev tawg, muab ob npaug ntawm kev ruaj ntseg ntawm cov qauv. Cov yam ntxwv no ua rau lawv hloov tsis tau nyob rau hauv qhov loj-span, siab-nce, thiab hnyav-load scenarios.

Hom Lub Npe ntawm Cov Qauv Hlau

(I) Kev faib tawm los ntawm Cov Qauv Txheej Txheem
Gateway Frame Structure: Cov qauv no, muaj cov kab thiab kab teeb, ua rau "lub rooj vag"-zoo li lub moj khaum, ua ke nrog kev txhawb nqa. Nws yog tsim rau cov nroj tsuag, logistics warehouses, supermarkets, thiab lwm yam qauv. Feem ntau qhov kev ncua deb ntawm 15 mus rau 30 meters, nrog qee qhov siab tshaj 40 meters. Cheebtsam tuaj yeem ua tiav hauv cov chaw tsim khoom, tso cai rau kev teeb tsa ntawm qhov chaw hauv tsuas yog 15 txog 30 hnub. Piv txwv li, JD.com's Asia No. 1 Logistics Park warehouses feem ntau siv hom qauv no.
Truss Structure: Cov qauv no muaj cov kab ncaj nraim txuas nrog cov nodes los tsim ib daim duab peb sab lossis trapezoidal geometry. Cov pas nrig tsuas yog raug rau axial quab yuam, tag nrho siv lub zog ntawm cov hlau. Cov qauv truss feem ntau yog siv nyob rau hauv lub ru tsev chaw ntau pob thiab choj lub ntsiab spans. Piv txwv li, kev kho dua tshiab ntawm Beijing Cov Neeg Ua Haujlwm Chaw Ua Haujlwm tau ua haujlwm cov qauv truss kom ua tiav 120-meter kem-dawb ncua.
Cov qauv tsim: Ib qho kev sib txuas ua ke tsim los ntawm kev sib txuas ntawm cov kab thiab kab sib txuas muaj cov phiaj xwm hauv pem teb hloov tau yooj yim thiab yog qhov kev xaiv tseem ceeb rau cov tsev ua haujlwm siab thiab tsev so.
Daim phiaj kab: Ib daim phiaj sib txuas uas muaj ntau tus tswv cuab, feem ntau nrog cov duab peb sab thiab cov square nodes, muaj kev ncaj ncees thiab zoo heev av qeeg. Lawv tau siv dav hauv tshav dav hlau terminals thiab cov chaw sib tham.

(II) Kev faib tawm los ntawm Load yam ntxwv
Cov tswv cuab Flexural: Sawv cev los ntawm kab teeb, cov tswv cuab no tuaj yeem khoov lub sijhawm, nrog compression rau saum thiab nro hauv qab. Lawv feem ntau siv H-sections lossis welded box seem, xws li crane beams hauv cov nroj tsuag, thiab yuav tsum ua kom tau raws li qhov yuav tsum tau muaj zog thiab qaug zog.
Axially loaded cov tswv cuab: Cov tswv cuab no tsuas yog raug rau axial nro / compression, xws li truss tie rods thiab grid member. Tie rods yog tsim los rau lub zog, thaum compression rods xav tau kev ruaj ntseg. Cov raj raj lossis lub kaum sab xis steel feem ntau yog siv. Eccentrically loaded Cheebtsam: Cov no yog raug rau ob qho tib si axial rog thiab dabtsi yog khoov lub sij hawm, xws li ncej kab. Vim lub eccentricity ntawm lub load ntawm lub beam xaus, symmetrical cross-sections (xws li lub thawv kem) yuav tsum sib npaug zog thiab deformations.

Core Advantages ntawm Steel Structures
(I) Cov cuab yeej cuab tam zoo heev
Lub zog siab thiab qhov hnyav yog qhov tseem ceeb tshaj plaws ntawm cov qauv steel. Rau ib qho kev ncua, qhov hnyav ntawm lub nqaj hlau tsuas yog 1/3-1/5 ntawm cov nqaj hlau. Piv txwv li, 30-meter span steel truss hnyav kwv yees li 50 kg / m, thaum lub pob zeb pob zeb hnyav tshaj 200 kg / m. Qhov no tsis tsuas yog txo cov nqi hauv paus (los ntawm 20% -30%) tab sis kuj txo cov kev cuam tshuam seismic, txhim kho cov qauv kev nyab xeeb seismic.
(II) Kev tsim kho siab
Tshaj li 90% ntawm cov qauv steel qauv yog prefabricated nyob rau hauv factories nrog millimeter-theem precision. On-site installation tsuas yog hoisting thiab txuas. Piv txwv li, 10-zaj dab neeg steel chaw ua haujlwm siv tsuas yog 6-8 lub hlis los ntawm kev tsim khoom kom tiav, 40% txo lub sijhawm tsim kho piv rau cov qauv tsim. Piv txwv li, ib qhov project prefabricated steel tsev nyob hauv Shenzhen tau ua tiav kev tsim kho ceev ntawm "ib pem teb txhua xya hnub," txo qis cov nqi ua haujlwm ntawm qhov chaw.
(III) Av qeeg muaj zog thiab kav ntev
Steel lub toughness enables steel lug dissipate zog los ntawm deformation thaum av qeeg. Piv txwv li, thaum xyoo 2008 Wenchuan av qeeg, lub Hoobkas steel qauv hauv Chengdu tau raug kev txom nyem me me thiab tsis muaj kev pheej hmoo ntawm kev tawg. Tsis tas li ntawd, tom qab kev tiv thaiv corrosion (galvanizing thiab txheej), hlau tuaj yeem muaj kev pab cuam lub neej ntawm 50-100 xyoo, nrog rau kev saib xyuas tus nqi qis dua li cov qauv pob zeb.
(IV) Environmental Protection thiab Sustainability
Cov nqi siv hluav taws xob ntau dua 90%, tso cai rau nws rov ua dua thiab ua tiav tom qab kev rhuav tshem, tshem tawm cov khoom siv pov tseg. Tsis tas li ntawd, kev tsim kho steel yuav tsum tsis muaj kev ua haujlwm lossis kev saib xyuas, yuav tsum tau ua haujlwm ntub dej tsawg kawg nkaus, thiab txo cov plua plav tawm los ntawm ntau dua 60% piv rau cov qauv ua vaj tse, ua raws li cov qauv hauv tsev ntsuab. Piv txwv li, tom qab kev rhuav tshem ntawm Ice Cube qhov chaw rau xyoo 2022 Beijing Winter Olympics, qee cov khoom siv tau rov qab siv dua hauv lwm txoj haujlwm, ua tiav cov peev txheej rov ua dua tshiab.

Kev siv dav dav ntawm Steel Structures
(I) Kev tsim kho
Cov vaj tsev pej xeem: chaw ntau pob, tshav dav hlau, rooj sib tham thiab chaw ua yeeb yam, thiab lwm yam, tso siab rau cov qauv hlau kom ua tiav qhov loj thiab dav tsim.

Cov tsev lag luam: Super-high-rise chaw ua haujlwm cov tsev thiab cov khw muag khoom, uas siv cov qauv hlau kom ua tiav cov qauv tsim thiab siv tau zoo.
(II) Kev thauj mus los
Choj engineering: Hla hiav txwv txuas hniav thiab kev tsheb ciav hlau txuas hniav. Cov choj hlau muaj qhov loj loj thiab muaj zog cua thiab av qeeg.
Rail Transit: Subway chaw nres tsheb canopies thiab lub teeb rail khiav kab teeb.
(III) Industrial
Cov nroj tsuag muaj: Heavy machinery nroj tsuag thiab metallurgical nroj tsuag. Cov qauv hlau tuaj yeem tiv taus cov khoom siv loj thiab pab txhawb kev hloov khoom siv tom ntej.
Cov chaw warehouses: Cold chain warehouses and logistics centers. Portal thav duab qauv ua tau raws li qhov yuav tsum tau ua kom loj-ntev thiab ua kom nrawm thiab ua haujlwm sai.
(IV) Zog
Cov chaw fais fab: Thermal power plant main buildings and transmission towers. Cov qauv hlau yog tsim rau cov khoom hnyav thiab hnyav sab nraum zoov. Lub Zog Tshiab: Cua turbine yees thiab photovoltaic mounting systems feature lub teeb yuag steel qauv kom yooj yim rau kev thauj mus los thiab kev teeb tsa, txhawb kev txhim kho lub zog huv.
