Qhov Loj: H450 × 250 × 10 × 12 ~ H500 × 250 × 12 × 14

Lus Cim: Cov kab ke ntawm qhov dav kawg yog me ntsis loj dua los xyuas kom meej cov qauv kev ruaj ntseg nyob rau hauv qhov tsis sib xws load faib.

 

Bracing (Sab saum toj Chord & Hauv qab Chord): Round steel los yog lub kaum sab xis steel, siv los tiv thaiv kab rov tav rog (cua, av qeeg) thiab tswj kev ruaj khov.

Round Steel: φ20 ~ φ25

Lub kaum sab xis steel: L80 × 6 ~ L100 × 8

Tie Rods: Cov yeeb nkab steel lossis cov hlau puag ncig, siv los hloov cov kab rov tav nro ntawm trusses.

Cov yeeb nkab steel: φ114 × 4 ~ φ140 × 5

Round Steel: φ22 ~ φ28

 

Purlins (ru tsev): C-section steel lossis Z-section steel, yoog rau lub ru tsev load thiab ncua.

Qhov Loj: C200 × 70 × 20 × 3.0 ~ C250 × 75 × 20 × 3.5

Phab ntsa Beams: C-section steel, piv rau phab ntsa load thiab qhov siab.

Qhov Loj: C180 × 70 × 20 × 2.5 ~ C220 × 70 × 20 × 3.0

 

High-Lub zog Bolts: Qib 10.9, sib piv cov ntu loj ntawm trusses, kab thiab bracing, nrog kub -dip galvanizing anti- kev kho corrosion.

Tus kheej -tapping Screws thiab Rivets: 304 stainless hlau, siv rau kev sib txuas purlins, phab ntsa kab teeb thiab ru tsev / phab ntsa panels.

 

Cov ncauj lus kom ntxaws cov ntaub ntawv txheeb xyuas yog nyob ntawm thaj tsam ntawm lub tsev tag nrho ntawm 18,620 ㎡, qhov loj me ntawm cov lus pom zoo thiab qhov kev paub txog tus nqi ntawm 38 kg / ㎡. Cov kev tawg tshwj xeeb ntawm txhua yam yog raws li hauv qab no (rau cov lus hais thiab cov ntaub ntawv npaj siv):

Hom Lub Npe	Steel Consumption Index (kg/㎡)	Tag nrho Steel Consumption (tons)	Loj	Lus hais
Main Trusses (Sab saum toj Chord, Hauv qab Chord, Web Members)	18 ~ 22	372.4	52.6%	Raws li qhov nruab nrab Performance index ntawm 20 kg/㎡, lub ntsiab quab yuam- bearing Cheebtsam
Hlau Kab	8 ~ 10	167.6	23.7%	Raws li qhov ntsuas nruab nrab ntawm 9 kg / ㎡, sib piv 17.4m eaves qhov siab
Bracing thiab Tie Rods	3 ~ 4	65.2	9.2%	Raws li qhov nruab nrab qhov ntsuas ntawm 3.5 kg / ㎡, ua kom muaj kev ruaj ntseg
Purlins thiab Phab Ntsa Beams	5 ~ 6	102.4	14.5%	Raws li qhov ntsuas nruab nrab ntawm 5.5 kg / ㎡, suav nrog lub ru tsev thiab phab ntsa pob txha
Fasteners thiab Accessories	0.5 ~ 1	9.3	1.3%	Nrog rau siab - lub zog bolts, tus kheej -tapping screws, thiab lwm yam.
Tag nrho	38	716.9	100%	Kev sib txawv me ntsis los ntawm tag nrho cov kwv yees (± 1.3%) vim qhov sib npaug

 

 

Hom qauv:Portal Ncej / Truss Rhiavnrog loj span thiab siab eaves, yuav tsum tau ntau dua steel noj dua li cov kev cob qhia zoo tib yam.

Cov xwm txheej hauv cheeb tsam: cua thiab daus loads hauv ntug dej hiav txwv thiab toj siab ntawm Peru feem ntau tsis loj, thiab tsis muaj qhov txias txias, yog li tsis tas yuav tsum tau siv cov hlau ntxiv rau kev tiv thaiv txias.

Kev paub tus nqi (Trusses + Steel Kem + Bracing + Purlins + Roof thiab Phab Ntsa Skeleton):

Ordinary Low Rhiav: 25 ~ 30 kg /㎡

Loj -span Truss nrog Eaves Qhov siab tshaj 15m:35 ~ 45 kg / hli㎡

Qhov project no adopts lubnruab nrab -tus nqi siab ntawm 38 kg /㎡rau kev kwv yees, xav txog qhov kev teeb tsa trapezoidal thiab tsis sib npaug ntawm kev thauj khoom.

 

 

Total Steel Consumption=Tsev Cheeb Tsam × Steel Consumption Index ÷ 1000

18620 ㎡ × 38 kg / ㎡ ÷ 1000 ≈7 07,6t

Pom zoo Quotation / Cov Khoom Npaj Ntau Yam: 650 ~ 840 tons

Economical Design: Hais txog650t ua(optimized seem loj, haum rau dav load tej yam kev mob)

Safe / Hnyav Load / High Standard Design: Txog840t ua(conservative tsim, haum rau siab load los yog nruj code cai)

 

 

Local Cua Load, Snow Load thiab Seismic Coefficient: Cov cheeb tsam sib txawv hauv Peru (coastal vs. toj siab) muaj qhov sib txawv ntawm cov khoom thauj, uas yuav cuam tshuam ncaj qha rau seem loj ntawm cov khoom.

Seb puas muajcranes, tshem tawm loads thiab ru tsev nyob loads: Qhov sib ntxiv ntawm cranes lossis lwm yam khoom hnyav yuav ua rau muaj kev siv hlau ntau ntxiv.

Seb lub ru tsev / phab ntsa txais yuavhnyav- lub luag haujlwm vaj huam sib luag thiab lub thickness ntawm thermal rwb thaiv tsev paj rwb: Heavy- cov vaj huam sib luag yuav ua rau lub ru tsev load, thiab cov ntaub thaiv thermal rwb thaiv tsev tuab dua yuav cuam tshuam rau tag nrho cov khoom xa tawm.

Hom Truss:Tube Truss / H-section Steel Truss / Angle Steel Truss: Ntau hom truss muaj sib txawv steel noj, thiab raj truss feem ntau muaj ntau dua steel noj dua lub kaum sab xis steel truss.

Hluav taws kub thiab Corrosion Resistance Levels thiab Peruvian Local Steel Qib (xws li Gr.50): Cov hluav taws kub thiab corrosion kuj yuav ua rau cov nqi thiab steel noj, thiab cov qib steel sib txawv yuav cuam tshuam rau qhov kev xaiv loj ntawm seem.

Yog tias koj tuaj yeem muab cov ntaub ntawv hauv qab no:

Qhov chaw tshwj xeeb (lub nroog twg hauv Peru / ntug hiav txwv lossis toj siab)

Seb puas muaj cranes thiab ru tsev loads

Kuv tuaj yeem muab qhov tseeb ntau dua thiab kev puas tsuaj (cov qauv tseem ceeb / purlins / bracing) raws liPeruvian cov cai.
