Uku hakusi kutadza kwemhando - iko kutadza kwekodhi. Makodhi makodhi ndiwo mutauro wedunhu weinjiniya. Dhizaina chivakwa chimwe chete kune akasiyana makodhi uye iwe unowana akasiyana simbi tonnage, saizi yenhengo, kudzika kwekudhirowa uye mitengo. Sarudza kodhi isiriyo, uye rework inotangazve kubva padanho rekugadzira.
Ichi chinyorwa chinojekesa zvinhu zvina: panoshanda imwe neimwe yeayo mana makuru masisitimu ekodhi, mamepu emamaki ezvinyorwa kune mumwe nemumwe, chimwe chinhu chinotonhora-mamiriro ekunze mapurojekiti anowanzo kupotsa, uye zvekunyora muRFQ yako.
Iwo mana Makuru Makodhi Systems: Ona Painoshanda Imwe neimwe Pakungotarisa
Dhizaini Makodhi neNzvimbo
| Nharaunda / rudzi rweprojekiti | Dhizaini kodhi system | Rodha kodhi | Common simbi mamakisi |

Zvinyorwa zviviri:
- BS 5950 yakatsiviwa neEurocodes uye inongowanikwa mune mamwe mapurojekiti enhaka. Mapurojekiti matsva eUK anotevera maEurocode pamwe neUK National Annex.
- Australia/New Zealand inoshandisa AS 4100, inosangana nemamwe mapurojekiti echitsuwa chePacific. Mazhinji mapurojekiti epasi rese anosarudza pakati peEurocode uye US zviyero.
Sei Chivako Chimwechete Chichiwana Mitengo Yakasiyana
Imwe neimwe sisitimu inosiyana mukubatanidza mitoro, kuchengetedza zvinhu uye buckling curves. AISC inoshandisa LRFD kuramba zvinhu; maEurocode anoshandisa chikamu chekuchengetedza zvinhu γM. Iine imwecheteyo 355 MPa giredhi simbi, zvinotenderwa kushushikana zvinobuda padyo pamativi ese, asi zvikamu zvenhengo uye simbi tonnage zvinosiyana zvinooneka. Munzvimbo dzine mhepo huru, ASCE 7 uye EN 1991 inobata mhepo yekumanikidza coefficients zvakasiyana, uye mutsauko wematani unoratidza zvakananga mumutengo.
Saka vatengesi vaviri vanoshanda kumakodhi akasiyana vari kutora zvivakwa zviviri zvakasiyana. Makotesheni akaenzaniswa anoda macode anowirirana.
Material Giredhi Mepu: Kunenge Hazvirevi Kuenzana

Q355B ≈ S355JR ≈ A572 Gr.50. Kusimba kwegoho kuri mumhando imwechete. Asi iyo "inofungidzira" inongobata pachiyero chesimba.
Iyo Item Inotonhora-Mamiriro Ekunze Mapurojekiti Anowanzo Kupotsa: Impact Kuoma
Iyo suffix tsamba inoreva tembiricha yekuedza:
- B / JR: 20 ° C kukanganisa bvunzo(mamiriro ekunze)
- C / J0: 0 ° C maitiro ekuedza
- D / J2: -20 °C kukanganisa bvunzo(yakakwirira-latitude, inotonhora-yechando nzvimbo)
Mumapurojekiti muCanada, Northern Europe, Russia uye zvikamu zveCentral Asia, tembiricha yemuno inogona kudonha pasi -20°C. Muzviitiko izvi unofanira kutenga Giredhi D / J2 simbi. Kutsiva Giredhi B simbi nekushandurwa kwesimba kunoyera iyo account yesimba asi kwete iyo yakaoma account - uye njodzi yekudzika-tembiricha brittle kutyoka inopfuudzwa kumuridzi.
Kondirakiti yekutenga inofanirwa kutsanangura giredhi rekuyedza giredhi zvichibva pane yakaderera dhizaini tembiricha panzvimbo yeprojekiti.
Welding uye mabhaudhi Tevera iyo Code
| Item | Eurocode system | US standard system |
| Simbi chimiro kuuraya / welding | EN 1090 / EN ISO 15614 / 9606 | AWS D1.1 |
| High-simba mabhaudhi | Giredhi 10.9 (ISO 898-1) | F3125 A325/A490 |
| Material certificates | EN 10204 Rudzi 3.1/3.2 | Mill Test Report |
Mabhoti haangogone kuchinjika nekushandura masendimita kuita mamirimita. US-standard A490 inoda yakakwirira yekumisikidza kunyepedzera pane yakajairwa torque yeChinese 10.9S. Pakutsvedza kwenzvimbo yekukweshana: sandblasting plus inorganic zinc-rich pendi patsika yekuChina inopa inosvika 0.45-0.5, nepo US miyero inoshandisa Kirasi A (0.30)/Kirasi B (0.50). Pasina ratidziro yekubatanidza inopesana neiyo inoenderana sisitimu, iwe unozosimudzirwa kumusoro pakugamuchirwa.
Zvinhu Zvina Zvekunyora Pazasi muRFQ Stage
- Dhizaini kodhi: kodhi inozivikanwa nenyika yeprojekiti - isa muRFQ
- Rodha parameters: kumanikidzwa kwemhepo yemunharaunda, mutoro wechando uye seismic chikamu (semuenzaniso, ASCE 7 saiti yekumhanya kwemhepo)
- Steel impact giredhi: zvichibva pane hushoma tembiricha yemuno, nyika B/C/D kana JR/J0/J2
- Kuitwa & kugamuchirwa zviyeroEN 1090 kirasi yekuuraya (EXC), welding system, yechitatu-bato rekutarisa zvinodiwa
Kuwana iyo kodhi padanho rekubvunzurudza hapana mari; kuita zvisizvo pakugamuchirwa kunodhura kushandazve kwakazara.
Sei Sarudza ZM-Besta
Yakavambwa muna 2006, ZM-Besta ikambani yakanyorwa muBeijing Stock Exchange uye iri pakati peVepamusoro makumi mashanu muindasitiri yekugadzira simbi yekuChina, ine mabhesi mashanu ekugadzira uye 300,000 m² yenzvimbo yekuvaka fekitori.
Multi-Code Dhizaini Kugona
- Multiple dhizaini software mapakeji anomhanya nenzira yakafanana - PKPM, 3D3S, MIDAS, STAADPRO, nezvimwe.
- Dhizaini uye kubvunza masevhisi kune mhiri kwemakungwa vatengi pasi peakawanda ekunze kodhi masisitimu
- Ruzivo rwevakuru mukugadzira mepu yegiredhi (semuenzaniso, Q355B vs S355JR)
Certification System
- EN 1090 European certification
- Triple-system certification: ISO 9001 / ISO 14001 / ISO 45001
- Kirasi-A specialty qualification yechiedza simbi chimiro engineering dhizaini; Giredhi-1 qualification yesimbi chimiro engineering chibvumirano
Dhizaini-yekugadzira-kuisirwa pasi pechinhu chimwe chinozvidavirira. Makodhi, zvishandiso, welding uye kugamuchirwa inovhara loop mukati meiyo imwechete system, ine mashoma mainterfaces.
FAQ
Q1: Ko simbi yekugadzira dhizaini makodhi anogona kusanganiswa?
A: Hazvikurudzirwi. Musanganiswa wemutoro, tsananguro yezvinhu, nzira dzekugadzira yekubatanidza uye miganho yekutsauka zvese zvinofanirwa kubva kune imwe system. Kusanganisa makodhi kunogona kukonzera kukanganisa kwekubatanidza kana kubata-kumusoro pakugamuchirwa. Kana kuchinjisa-referensi kuchidikanwa kune chimwe chirongwa, nyika dzese dzinogumira dzinofanirwa kusimbiswa zvakare neiyo chaiyo zvinhu zvivakwa.
Q2: Inogona Q355B yakananga kutsiva S355JR?
A: Mumamiriro ekunze ekunze, simba uye magiredhi (20°C) anofananidzwa, saka kutsiva kunogamuchirwa. Asi kune inotonhora-yemamiriro ekunze mapurojekiti (-20 ° C kirasi), iwe unoda Q355D/S355J2, uye kabhoni yakaenzana uye maitirwo ewelding anofanirwa kusimbiswa patsva nekodhi yeprojekiti. Chisarudzo chekutsiva chinofanira kusimbiswa nekunyora neboka rekugadzira.
Q3: Is EN 1090 certification yakafanana neEurocode dhizaini?
A: Kwete. EN 1090 inotonga kugadzirwa kwekugadzira uye kutonga kwekugadzira fekitori (chinodiwa chekumaka CE); iyo kodhi yekugadzira ndeye EN 1993 Eurocode 3. Ivo vakazvimiririra, uye mapurojekiti eEurocode anowanzoda ese ari maviri.
Q4: Ndeipi kutarisirwa kwakakosha kunodiwa pakusarudza simbi yemapurojekiti epamusoro-latitude?
A: Mapoinzi maviri: sarudza D/J2 kukanganisa mamakisi zvichibva pane hushoma tembiricha yemuno; uye simbisa akasimba weld mhando mamakisi uye kabhoni yakaenzana kutonga kudzivirira yakaderera-tembiricha brittle kuputsika. Isu tinokiya zvinodikanwa zvekuyedza muchibvumirano chekutenga zvinoenderana nemamiriro ekushisa eprojekiti.
