Ubalo malunga nama-60% omsebenzi uwonke kwimakethi yolwakhiwo lwentsimbi yase-UK, icandelo lezakhiwo zemizi-mveliso ezinomgangatho omnye liye lachulumancisa kakhulu kule minyaka imbalwa idlulileyo kwaye ibonakalisa uphawu oluncinci lokurhoxa.
Ezi zakhiwo zineendlela ezahlukeneyo zokusetyenziswa, kubandakanywa iindawo zokusebenzela, iifektri kunyeiivenkile zokuthengisaukukhankanya ezimbalwa, kodwa uninzi lwakhiwe njengeendawo zokugcina iimpahla, ezidla ngokubizwa ngokuba 'ziishedi'.
Intsimbi yolwakhiwo sisisombululo esithandwayo sokuqulunqa iziko lokuhambisaukwakhiwa, kunye nesabelo semarike esidlula i-90%.Steel inikeza inani leenzuzo, ezifanaisantyayokwakhiwa kunye nokukwazi ukudala ngokufanelekileyo ixesha elideiindawo zangaphakathi, ezibaluleke kakhulu kwiindawo zokugcina iimpahla.
Iindleko kunye nokuhanjiswa kwamaziko okuhanjiswa kuphuculwe kakhulu kumaxesha amva nje, ngenxa yokuba akukho nxalenye incinci kusetyenziso olusebenzayo lwefreyimu ye-portal ngoonokontraka abasebenza ngentsimbi.uyila kwaye wakheisivumelwano.
Iinzuzo zokuyila kunye nokwakha ziquka into yokuba ikontraki yensimbi inokukhawuleza kwaye ilungelelanise ngokufanelekileyo aiziko lokuhambisaisakhelo sentsimbi.
"Sikhetha olu hlobo lwekhontrakthi njengoko sinokusebenzisa amava ethu amaninzi kumaziko okuhambisa ukuqinisekisa ukuba isakhelo sentsimbi sisebenza ngokufanelekileyo," utshilo uCaunton Engineering Senior Structural Engineer Colin Winter.
Umzekelo walo msebenzi yiprojekthi yobuNjineli beCaunton eKingston Park, ePeterborough, apho iyile khona,yenziwe, ibonelele kwaye yakha amaziko amathathu okusasaza egameni leGlencar Construction.
Ithengwe ngumphuhlisi weFirethorn Trust ekuqaleni kwalo nyaka, indawo yeehektare ezingama-21 ibekwe kufutshane nabahlali abakhoyo i-Amazon, i-IKEA kunye ne-DART kwaye ibonelela ngoqhagamshelo olulungileyo njengoko iphakathi kweemayile ezimbini ze-A1(M) ekudibaneni kwe-17.
UMlawuli woPhuhliso lweFirethorn Trust uPaul Martin uthi: “Sichukumisekile yirekhodi yeGlencar ekuhambiseni amaziko akumgangatho ophezulu wolu hlobo, kwaye sisebenza ngokusondeleyo neqela ukwenza umbono wethu ngePeterborough South uphile.
“Olu phuhliso luchaziweyo kakhulu, lwe-net-zero carbon yenzelwe ukuqhubeka nokuqhuba utyalo-mali kunye namathuba engqesho kwindawo eye yaba yenye yezona ndawo zikhula ngokukhawuleza e-UK.Iskimu siza kuhlangabezana nemfuno eyandayo yabahlali yomgangatho, izithuba ezizinzileyo neziguquguqukayo.
Ukudala malunga ne-46,450m² yendawo yolungiselelo kuzo zonke iiyunithi ezintathu, iskimu siya kuhanjiswa kwi-net-zero carbon kulwakhiwo kwaye sijolise kuhlelo 'Olugqwesileyo' lwe-BREEAM.Iziseko zophuhliso ezizinzileyo ziya kubandakanya ngaphezulu kwe-3,700m² yezixhobo ze-photovoltaic njengomgangatho, iindawo zokutshaja iimoto zombane ezingama-48, kunye ne-15% yokukhanyisa eluphahleni.
Zontathu ezi zakhiwo zizakhelo ze-portal kwaye zinoyilo olufanayo kunye nengqiqo, nangona zonke zinobukhulu obahlukeneyo.Esona sakhiwo sikhulu kweso siza, esaziwa ngokuba yiSakhiwo sama-300, naso yayisisakhiwo sokuqala ukwakhiwa.Esi sakhelo se-portal siquka iziphako ezine ze-31m-wide kunye ne-168m ubude.
Njengazo zonke izakhiwo kwisiza, iintsika zisekelwe kwiziseko ezifunjiweyo kwaye amalungu omjikelezo ahlukaniswe kwizithuba ze-8m.Ngaphakathi, zicwangciswe kwi-hit-and-miss configuration, oku kuthetha ukuba kukho ikholomu nganye kwi-16m ecaleni kwemigca yentlambo, ukudala indawo evulekileyo yeplani ngaphakathi kwesakhiwo.
Iikholomu zentlambo zibonisa ezona zinto zinzima kakhulu kwiprojekthi njengoko zinobunzima obuyi-3.5t nganye.
Zonke izakhiwo zinophahla olugobileyo, oluye lwenziwa kunye namacandelo e-rafter e-facetted ngaphakathi kwe-spans.Kuphahla lweSakhiwo esingama-300, isithuba ngasinye sasifuna amacandelo amathathu anamacala, awayedityaniswe phantsi aze anyuswe endaweni yawo njengecandelo elinye elipheleleyo eliziimitha ezingama-31 ubude.
Ukuphela kwegable yesakhiwo esingu-300 kunebhloko yeofisi enemigangatho emibini, enendawo yokugcina impahla ngaphakathi komgangatho ophantsi ongaphantsi kophahla.
“Isakhiwo ngasinye kwezi zithathu sineeofisi, kwaye ezi ndawo beziziindawo zokuqala ukwakhiwa kwisakhiwo ngasinye njengoko ziyizowuni zesakhiwo ezinomsebenzi omninzi wemisebenzi elandelayo,” utsho uManejala weCaunton Engineering Contracts uAdrian Downing. .
Nje ukuba iiofisi zakhiwe bebengadingi misebenzi yethutyana phambi kokuba kuqale isakhelo esiphambili, njengoko bebezixhasa kuba imigangatho yabo ehlanganisiweyo kunye neebracing bezinika uzinzo.
Iibhloko zeofisi zonke ziyi-10m-wide-wide column-free structures, ezenziwe ngeentsimbi zetsimbi ezixhasa i-metal decking kunye ne-concrete topping.Ukongeza ukuguquguquka okuthile kwixesha elizayo kwiprojekthi, inqanaba eliphezulu linesiciko esihlanganisiweyo (uphahla), esinokuguqulwa sibe ngomnye umgangatho weofisi.Ukwenza oku kungqinwa kwixa elizayo, iziseko zesakhiwo ziyilwe ngomthamo owongezelelweyo.
Incinci kancinane kwaye ibekwe kufuphi neSakhiwo sama-300, iSakhiwo sama-200 sasilandelayo esaza kumiswa.Esi sakhiwo sinezipani ezithathu eziziimitha ezingama-30 ububanzi kwaye ubude bungama-136m.Ngokufana nommelwane wayo omkhulu, uphahla olugobileyo lwenziwe lunamalungu amathathu anamacala.Eli ziko lonikezelo linendawo enemigangatho emibini.
Isakhiwo sesithathu kunye nesincinci, esaziwa ngokuba yi-Building 100, yi-twin-span portal frame, ene-112m ubude.I-span nganye yi-37m ububanzi kwaye iqulathe amalungu amane entsimbi abumba uphahla lwayo olugobileyo.
Ngamalungu amaninzi entsimbi afunekayo kwisithuba ngasinye, inkqubo yokwakhiwa kophahla lwesi sakhiwo yayahluke kancinane.Isebenzisa iicranes ezimbini ezihambayo, iyunithi nganye yaphakamisa amacandelo amabini adityaniswe kwangaphambili kwaye yawagcina endaweni yawo, ngelixa i-splice esembindini yenziwa ukugqiba sonke isithuba.
Isakhiwo se-100 sinebhloko yeofisi enomgangatho omnye, kodwa ngokuguquguquka okufanayo okwakhiwe ngaphakathi, oku kunokuguqulwa kube yimigangatho emibini ukuba bekufuneka.
Amaziko amathathu osasazo e-Kingston Park kulindeleke ukuba agqitywe ekupheleni konyaka.
