Yakagadzirwa kubva-saiti neiyo isingachashanda Portland Supreme Steel Company, yakachekwa kuita zvikamu zvikuru zvitatu, ndokuzotakurwa kuenda kunzvimbo iyi.
Kuzadzikisa zvinodiwa nekuona uye zvekuvaka zvaireva kushandisa zvinhu zvaizozadzisa zvinangwa zvepurojekiti zvakanyanya zvakasiyana, zvese zveunyanzvi uye zvechimiro. Izvi zvinoreva kushandisa mapaipi - apa 3.5 ″ uye 5 ″.corten (ASTM A847) simbi yekugadzira tubing yakagadzirirwa zvivakwa zvinoda welded kana mabhaudhi mapombi anoiswa pachena (pamwe makiyi egirinhi anoiswa pachena). enzanisa necanopy yesango.
Ed Carpenter, mugadziri uye muimbi anonyanya hunyanzvi hwekumisikidza veruzhinji, akati aive nezvinangwa zvakawanda mupfungwa paakabata zambuko. Pakati pazvo, zambuko rinofanirwa kubatanidzwa mumamiriro esango, inova kuenderera kwekunzwa uye ruzivo rwenzira, uye inofanirwa kuve yakapfava uye yakajeka sezvinobvira.
“Nemhaka yekuti chimwe chezvinangwa zvangu zvakakosha pakugadzira bhiriji chaive chekuita kuti zambuko rive rakapfava uye rive pachena, ndaida zvinhu zvinonyanya kushanda nesimba uye magadzirirwo ainyatsoita—saka, matrus ane mativi matatu,” anodaro Carpenter, anofarirawo zvekunze. .Kumhanya panzira huru yePortland kweanopfuura makore 40.”Unogona kuigadzira uchishandisa zvimwe zvinhu, asi pombi dzesimbi kana kuti pombi inongova chisarudzo chine musoro.
Kubva pakuona kwekuvaka, kuita zvese izvi hakusi nyore.Stuart Finney, injinjiniya muPortland hofisi yeinjiniya KPFF uye aimbove maneja wepurojekiti yebhiriji, akati zvakabudirira kupinza zvikamu zvese pamubatanidzwa weTYK apo mapaipi ese anotsigira anosangana pamwe ndiyo yakanyanya kuoma.Chimwe chikamu chekuedza kwese.Kunyanya, marudzi ese akasiyana-siyana anodiwa, akasiyana-siyana emakona anodiwa, akasiyana-siyana emakona anodiwa, akasiyana-siyana emakona. kwakakonzera zvinetso zvakakomba nokuda kweboka rokuvaka.
“Chaizvoizvo mapfundo ose akasiyana,” anodaro Finney, uyo adzidzira basa racho kwemakore 20.” Vaifanira kugadzira majoini ose akanyatsokwana kuitira kuti pombi dzose idzi dzibatanidzwe pamwe chete panzvimbo imwe chete, uye kuti vakwanise kuwana masimbi akakwana papombi dzose.

Carpenter akati kusanganisa manzwi mazhinji nemanzwi pachirongwa ichi zvakanetsa, asi zvakakosha.
"Ndinofunga kuti chiitiko chakakosha zvikuru kubatana kukuru kwenharaunda, kudada kukuru, uye kubatana kukuru - vanhu vari kubhadhara izvozvo," Carpenter akadaro. "Kwete vanhu chete, asi maguta nematunhu.
Finney akawedzera kuti iye nechikwata chake, uye vagadziri vane basa rekuita kuti magadzirirwo ave nehupenyu, vaifanira kukunda akawanda ematambudziko mu3D modelling yavakaita, nekuda kwekuoma kwese kwemajoini uye mafittings.
"Tiri kushanda nevatsananguri vedu kuti tive nechokwadi chekuti mhando dzese dzakamira nekuti zvakare, hapana nzvimbo yekukanganisa kune akawanda emajoini aya nekuda kwekuoma kweiyo geometry," Finney akadaro." Chokwadi zvakaoma kupfuura mazhinji. Mabhiriji mazhinji akati twasa, kunyangwe akakombama ane macurves, uye zvekushandisa zviri nyore.
"Nekuda kweizvozvo, pane zvakawanda zvishoma zvinonetsa zvinouya muchirongwa ichi. Ndingangoti zvakaoma kupfuura [chirongwa] chenguva dzose. Zvinotora basa rakawanda kuti munhu wese aite kuti chirongwa ichi chibudirire."
Zvisinei, maererano neMuvezi, pakati pezvinhu zvakakosha mukuoma kwebhiriji, chii chinoita kuti zambuko riite basa raro rose ndiro denga rakakombama. Zvinokosha here kunetsa kuita izvi? Zvizhinji, hongu.
"Ndinofunga kuti dhizaini yakanaka inowanzotanga nekuita uye yoenda kune chimwe chinhu," Carpenter akadaro." Ndizvo chaizvo zvakaitika pabhiriji iri. Ini ndinofunga kwandiri, chinonyanya kukosha dhizaini yakakomberedzwa. Panyaya iyi, handisi kunyatsonzwa zvakanaka nezvesiwiti bar nekuti nzira yacho yese haina kutenderera uye inokotama. Ini handidi kukona nekuruboshwe ndozopinda pazambuko.
