Mukugula nyumba yopangira zitsulo kuchokera kwa ogulitsa aku China. Mumakondwera ndi zojambulazo ndi mawuwo. Kenako, musanasainire, woyang'anira zowunikira mdera lanu akunena chinthu chimodzi: zojambulazo sizingavomerezedwe.
Uku sikulephera kwamtundu - ndikulephera kwa code. Ma Code Design ndi chilankhulo chachigawo cha engineering. Konzani nyumba yomweyi kumitundu yosiyanasiyana ndipo mumapeza matani achitsulo osiyanasiyana, makulidwe a mamembala, kuya kwa kujambula ndi mitengo. Sankhani code yolakwika, ndipo kukonzanso kumayambanso kuchokera pagawo lopanga.
Nkhaniyi ikufotokoza momveka bwino zinthu zinayi: pomwe njira zinayi zazikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikuluzikulu,chinthu chimodzi chomwe mapulojekiti anyengo yozizira nthawi zambiri amaphonya, ndi zomwe mungalembe mu RFQ yanu.
Njira Zinayi Zazikulu Zamakono: Onani Pamene Iliyonse Ikugwira Ntchito Mwachidule
Ma Code Design ndi Dera
| Chigawo / mtundu wa polojekiti | Design code system | Load kodi | Makalasi achitsulo wamba |
| US / America | Chithunzi cha AISC360 | Chithunzi cha ASCE7 | A36 / A572 Gr.50 / A992 |
| Europe, Middle East ndi ambiri ku Africa | Eurocode 3 (EN 1993) | EN 1991 | S235/S275/S355 |
| UK (mapulojekiti obadwa nawo) | Chithunzi cha BS5950 | Chithunzi cha BS6399 | S275/S355 |
| Ntchito zaku China komanso zaku China zotsogozedwa ndi mayiko akunja | Mtengo wa GB50017 | Mtengo wa GB50009 | Q235B / Q355B |
| Mayiko ena | Nthawi zambiri ma Eurocode kapena ma code akomweko | Zimatengera dziko | Kuti zitsimikizidwe ndi mainjiniya akomweko |
Zolemba ziwiri:
- BS 5950 yalowetsedwa m'malo ndi Eurocodes ndipo imangowonekera muzolemba zina za polojekiti. Ntchito zatsopano zaku UK zimatsata ma Eurocode kuphatikiza UK National Annex.
- Australia/New Zealand imagwiritsa ntchito AS 4100, yomwe mapulojekiti ena azilumba za Pacific amakumana nawo. Ntchito zambiri zapadziko lonse lapansi zimasankha pakati pa ma Eurocode ndi US miyezo.
Chifukwa Chimene Nyumba Imodzi Imapeza Mitengo Yosiyana
Dongosolo lililonse limasiyana pakuphatikiza katundu, zinthu zachitetezo ndi ma curve okhotakhota. AISC imagwiritsa ntchito LRFD kukana zinthu; ma Eurocode amagwiritsa ntchito zinthu zina zachitetezo γM. Ndizitsulo zomwezo za 355 MPa giredi, kupanikizika kovomerezeka kumatuluka pafupi mbali zonse, koma magawo a mamembala ndi matani achitsulo amasiyana mowonekera. M'madera amphepo yamkuntho, ASCE 7 ndi EN 1991 amachitira mosiyanasiyana ma coefficients amphepo, ndipo kusiyana kwa matani kumawonekera mwachindunji pamtengo.
Chifukwa chake ogulitsa awiri omwe amagwira ntchito kumitundu yosiyanasiyana akutchula nyumba ziwiri zosiyana. Zolemba zofananira zimafunikira ma code osasinthasintha.
Kujambula Makalasi Ofunika: Pafupifupi Sikutanthauza Kufanana
Common Grade Equivalents
| China GB/T 1591 | Europe EN 10025 | US ASTM | Zokolola mphamvu |
| Q235B | Chithunzi cha S235JR | A36 | 235/250 MPa |
| Q355B | Chithunzi cha S355JR | A572 Gr.50 | 355/345 MPa |
| Q355C | Chithunzi cha S355J0 | - (pazofunikira zowonjezera) | 355 MPa |
| Q355D | Chithunzi cha S355J2 | - (pazofunikira zowonjezera) | 355 MPa |
Q355B ≈ S355JR ≈ A572 Gr.50. Mphamvu zokolola zili mumtundu womwewo. Koma "kuyerekeza" kumangogwira gawo lamphamvu.
Ntchito Yozizira ya Nyengo Yozizira Nthawi zambiri Imaphonya: Kuvuta Kwambiri
Chilembo chokwanira chimasonyeza kutentha kwa chiyeso:
- B / JR: 20 ° C kuyesa kwamphamvu(zanyengo)
- C / J0: 0 °C kuyesa kwamphamvu
- D / J2: -20 °C kuyesa kwamphamvu(zigawo zokwera, zozizira ndi zozizira)
M'mapulojekiti ku Canada, Northern Europe, Russia ndi madera ena a Central Asia, kutentha kochepa kumatsika pansi pa -20 ° C. Muzochitika izi muyenera kugula zitsulo za Gulu D / J2. Kulowetsa chitsulo cha Gulu B ndi kutembenuka kwa mphamvu kumalinganiza akaunti yamphamvu koma osati akaunti yolimba - ndipo chiopsezo cha kusweka kwachiwopsezo chochepa chimaperekedwa kwa eni ake.
Mgwirizano wogulira uyenera kufotokoza kalasi yoyesera zotsatira kutengera kutentha kwapangidwe kochepa pa malo a polojekiti.
Kuwotcherera ndi Bolts Tsatirani Khodiyo
| Kanthu | Eurocode system | US Standard System |
| Kukonzekera kwachitsulo / kuwotcherera | EN 1090 / EN ISO 15614 / 9606 | AWS D1.1 |
| Maboti amphamvu kwambiri | Gulu 10.9 (ISO 898-1) | F3125 A325/A490 |
| Zikalata zakuthupi | EN 10204 Mtundu 3.1/3.2 | Mill Test Report |
Maboti sangasinthidwe posintha mainchesi kukhala mamilimita. US-standard A490 imafuna kunyengerera kwapamwamba kwambiri kuposa torque wamba yaku China 10.9S. Pamalo otsetsereka: utoto wa sandblasting kuphatikiza utoto wokhala ndi zinki wochuluka pakuchita ku China umapereka pafupifupi 0.45-0.5, pomwe miyezo yaku US imagwiritsa ntchito Gulu A (0.30)/Class B (0.50). Popanda kutsimikizira kulumikizidwa motsutsana ndi dongosolo lofananira, mudzayimilira pakuvomerezedwa.
Zinthu Zinayi Zolemba Pansi pa RFQ Stage
- Design kodi: code yozindikiridwa ndi dziko la polojekiti - ikani mu RFQ
- Katundu magawo: kuthamanga kwa mphepo yam'deralo, kuchuluka kwa chipale chofewa ndi gulu la zivomezi (monga ASCE 7 liwiro lamphepo)
- Chitsimikizo chachitsulo: kutengera kutentha kochepa komweko, boma B/C/D kapena JR/J0/J2
- Kuphatikizika & kuvomereza miyezoTS EN 1090 Class execution (EXC), makina owotcherera, zofunikira kuyang'anira gulu lachitatu
Kupeza kachidindo pa nthawi yofunsira kulibe ndalama; kuchipeza molakwika pakuvomereza kumawononga kukonzanso kwathunthu.
Chifukwa Chosankha? ZM-Besta
Yakhazikitsidwa mu 2006, ZM-Besta ndi kampani yomwe ili m'gulu la Beijing Stock Exchange ndipo ili m'gulu la 50 Opambana pamakampani opanga zitsulo zomanga ku China, okhala ndi malo asanu opangira ndi 300,000 m² malo omanga fakitale.
Multi-code Design Kutha
- Mapulogalamu opanga mapulogalamu angapo amayendera limodzi - PKPM, 3D3S, MIDAS, STAADPRO, etc.
- Kupanga ndi kufunsira ntchito kwamakasitomala akunja pansi pa machitidwe angapo akunja akunja
- Kudziwa okhwima pakupanga mapu azinthu (monga Q355B vs S355JR)
Certification System
- EN 1090 European Certification
- Chitsimikizo cha machitidwe atatu: ISO 9001 / ISO 14001 / ISO 45001
- Kalasi-A wapadera kuyeneretsedwa kwa kuwala zitsulo kapangidwe zomangamanga zomangamanga; Chiyeneretso cha Grade-1 pakupanga chuma chaumisiri
Kupanga-kupanga-kukhazikitsa pansi pa gulu limodzi loyankha. Ma code, zipangizo, kuwotcherera ndi kuvomereza kumatseka kuzungulira mkati mwa dongosolo limodzi, ndi malo ochepa kwambiri.
FAQ
Q1: Kodi zilembo zamapangidwe achitsulo zingasakanizidwe?
A: Osavomerezeka. Kuphatikizika kwa katundu, matanthauzidwe azinthu, njira zopangira zolumikizirana ndi malire opatuka ziyenera kuchokera ku dongosolo limodzi. Kusakaniza manambala kungayambitse kulephera kwa kulumikizana kapena kuyimitsa pakuvomerezedwa. Ngati kufotokozera mwatsatanetsatane kuli kofunikira pa ntchito inayake, maiko onse oletsa malire ayenera kutsimikiziridwanso ndi zinthu zenizeni.
Q2: Kodi Q355B ingasinthe mwachindunji S355JR?
Yankho: M'madera abwino, mphamvu ndi mphamvu (20 ° C) ndizofanana, choncho kulowetsako kumakhala kovomerezeka. Koma pama projekiti a nyengo yozizira (-20 ° C kalasi), muyenera Q355D / S355J2, ndipo njira zofananira ndi mpweya ndi kuwotcherera ziyenera kutsimikiziridwanso motsutsana ndi code ya polojekiti. Chigamulo cholowa m'malo chiyenera kutsimikiziridwa mwa kulemba ndi gulu lojambula.
Q3: Kodi certification ya EN 1090 ndi yofanana ndi kapangidwe ka Eurocode?
A: No. EN 1090 imayang'anira kaphatikizidwe kabodza ndi kuwongolera kupanga fakitale (chofunikira pakuyika chizindikiro cha CE); kachidindo kamangidwe ndi EN 1993 Eurocode 3. Iwo ndi odziimira okha, ndipo mapulojekiti a Eurocode nthawi zambiri amafuna zonse ziwiri.
Q4: Ndi chisamaliro chanji chapadera chomwe chimafunika posankha zitsulo zamapulojekiti apamwamba kwambiri?
A: Mfundo ziwiri: sankhani magiredi okhudza D/J2 kutengera kutentha kochepa komweko; ndikukhazikitsa magiredi olimba a weld komanso kuwongolera kofanana ndi mpweya kuti mupewe kusweka kwa brittle fracture. Timatseka zofunikira zoyezetsa zotsatira mu mgwirizano wogula malinga ndi kutentha kwa polojekitiyi.
