Ubude bentsimbi kunye nobukhulu

I. Ubude bentsimbi kunye nobukhulu

Ubungakanani bentsimbi yentsimbi yeyona sayizi isisiseko sazo zonke iintlobo zentsimbi, ibhekisa kubude, ububanzi, ubude, ububanzi, iradiyasi, idiayasi yangaphakathi, ububanzi obungaphandle kunye nobukhulu bodonga njalo njalo. m), isentimitha (cm), imilimitha (mm).I-intshi ikwasetyenziswa kusetyenziso lwangoku, kodwa ayisiyoyunithi yomthetho yomlinganiselo.

Imilinganiselo yoluhlu lwentsimbi
Ukumisela ubungakanani boluhlu lwentsimbi ngumlinganiselo osebenzayo wokugcina izinto eziphathekayo.Irula yoluhlu yileyo apho ubude okanye ubude-ngobubanzi bungekho ngaphantsi kwesayizi ethile, okanye enye apho ubude okanye ubude-ngobubanzi bunikezelwa ngaphakathi koluhlu lwemilinganiselo.Iyunithi yemveliso inokuvelisa kwaye ibonelele ngokweemfuno zobukhulu.

Ubude obungenasiphelo (ubude obuqhelekileyo)
Apho ubukhulu bemveliso (ubude okanye ububanzi), kumgangatho omiselweyo ngaphakathi kobubanzi, kwaye awufuni ubungakanani obusisigxina obubizwa ngokuba ziinyawo ezingapheliyo.Ubude obungenasiphelo bukwabizwa ngokuba bubude obuqhelekileyo.Izixhobo zetsimbi ezihanjiswa ngomlinganiselo ongapheliyo ziyamkeleka nje ukuba zihanjiswa ngaphakathi kobude obuchaziweyo.Umzekelo, kwintsimbi eqhelekileyo engqukuva engekho ngaphezulu kwe-25mm, ubude bayo buhlala buchazwa njenge-4 ~ 10m, yonke intsimbi engqukuva phakathi kolu luhlu inokuhanjiswa.

3. Ubude

Ukusikwa kwisayizi emiselweyo njengoko kufunwa ngumyalelo kubizwa ngokuba yi-sizing.Xa ukuhanjiswa kwenziwa kubude obusisigxina, izinto zentsimbi kufuneka zibe nobude obuchazwe ngumthengi kwisivumelwano somyalelo.Ngokomzekelo, ukuba isivumelwano sichaza ukuba iimpahla zihanjiswa kubude obumiselweyo be-5m, izinto ezihanjiswayo kufuneka zibe yi-5m ubude.Naziphi na izinto ezimfutshane okanye ezinde kune-5m azifaneleki. Kodwa ngokwenene, ukuhanjiswa akunakuba yi-5m yonke ubude, ngoko ke kucacisiwe ukuba ukutenxa okuhle kuvunyelwe endaweni yokutenxa okubi.

4 amaxesha iinyawo

Ngokomlinganiselo omiselweyo womyalelo ofunekayo ukusika kwi-multiple yonke ibizwa ngokuba yi-multiple.Ubude besinyithi kufuneka bube yinto edibeneyo yobude obuchazwe nguMthengi kwisivumelwano somyalelo (obizwa ngokuba lunyawo olulodwa) (kunye nesarha). Ukuvula).Umzekelo, umthengi ufuna kwisivumelwano somyalelo ukuba ubude bonyawo olunye yi-2m, ngoko ubude bube yi-4m xa sisikwa kwiinyawo eziphindwe kabini, 6m xa sisikwe ku-3 iinyawo eziphindwe kabini, kunye nomlomo omnye okanye emibini yongezwa ngokulandelelanayo.

Ixabiso le-sawing lichazwe kumgangatho.Xa ubungakanani buhanjiswa, kuphela ukutenxa okulungileyo kuvunyelwe, kwaye akukho ntlukwano embi evunyelweyo.

5. Iinyawo ezimfutshane

Irula emfutshane enobude obungaphantsi komda osezantsi wobude obungenammiselo obuchazwe kumgangatho, kodwa ingekho ngaphantsi kobude obumiselweyo obuvumelekileyo, ibizwa ngokuba yirula emfutshane.Umzekelo, umgangatho wombhobho wamanzi negesi umisela ukuba i-10% inani lamaqhekeza) 2-4m ubude obufutshane bemibhobho yentsimbi ivumelekile kwibhetshi nganye.

6. Iinyawo ezimxinwa

Irula emxinwa yileyo ububanzi bayo bungaphantsi komda osezantsi wobubanzi obungenammiselo obuchazwe kumgangatho, kodwa ingabi ngaphantsi kobona bubanzi bumxinwa obuvumelekileyo. Ingqalelo kufuneka ihlawulwe kwisikali kunye nesikali esimxinwa esichazwe kwimigangatho efanelekileyo xa kuziswa impahla. kwizikali ezimxinwa.

二,Imizekelo yobude bentsimbi kunye nobukhulu

8. Inqaba yentsimbi

9. Ulwakhiwo lokuNxulumana neSola

Uncedo lweNkampani yethu:

1.Ixabiso:Inkampani yethu iseTianjin China.Kangangamashumi eminyaka, iTianjin ibe liziko loshishino lwentsimbi kunye nesiseko esikhulu sokuvelisa umbhobho wentsimbi eTshayina.Ikhonkco loshishino lwentsimbi kunye neemveliso zetsimbi lugqityiwe;Inomathiriyeli omkhulu kunye nezibonelelo zabasebenzi apha.Ngoko iintlobo zemibhobho yensimbi ezenziwe apha ziphelele kakhulu, umgangatho uphezulu, ixabiso lincedo kakhulu.NJENGEnkampani yeqela, iifektri zethu ezine zinokufumana ixabiso elincomekayo lemathiriyeli ekrwada ngenxa yokuthenga okuninzi kwebhetshi enye yezinto.Amaxabiso eemveliso ezithunyelwa ngaphandle ngawo onke amaxabiso eqela le-intro-group, ngoko ke sinenzuzo yexabiso ngaphezu kwabanye abathengisi ngaphandle abazimeleyo.

2.Ezothutho:Izixhobo zethu zokusila zikumgama oziikhilomitha ezingama-70 kuphela ukusuka kwizibuko laseTianjin, elilelona zibuko likhulu kumantla eTshayina, kunye neenqanawa ezithunyelwa kumazibuko angaphezu kwama-300 kumazwe angama-170.Inkampani yethu kuphela Ilula kakhulu kwaye igcina zombini ixesha kunye neendleko zokuhamba.

3.Inkonzo yokumisa enye:Njengenkampani yeqela, sinezixhobo ezine zokusila ezinendawo yokugcina impahla kunye nendawo yokucubungula, sinokukubonelela ngoluhlu olubanzi lweemveliso zentsimbi: i-hot rolled kunye nebandayo eyenziwe, kubandakanywa uluhlu olubanzi lwebar yomthengisi, i-structural and tubular products.Sinazo zonke izinto zentsimbi zasekhaya, zorhwebo kunye nezoshishino kunye neenkonzo onokuthi uzifune.Ngoko ukuba uthenga kuthi, into esinokubonelela ngayo yinkonzo yemveliso yensimbi enye.Igcina ixesha lakho elininzi lokuthenga kunye neendleko zokukhangela.

4. Umthamo weMveliso kunye nokuhanjiswa:

Sinomthamo omkhulu wemveliso, kwaye sithumela ngaphandle kweetoni ezingaphezu kwama-3500 ngeveki (phantse i-150 20 yezikhongozeli ze-GP), sinokuhambisa iimpahla Ngeentsuku ezingama-20-30 emva kokufumana idiphozithi ye-T / T okanye i-L / C.Kwii-odolo ezikhethekileyo eziphuthumayo, sinokunciphisa ixesha elihamba phambili ukuya kwiintsuku ze-10.

5. Yenziwe ngokwemigangatho eyahlukeneyo, Dibana nemigangatho eyahlukeneyo:
