Kunendaba engavamile ngezinsimbi phakathi neMpi Yezwe II.Ukuze kuhlangatshezwane nesidingo sezikhali, imikhumbi nezimoto zokulwa, uthango oluhlukahlukene nezinsimbi eDolobheni laseLondon zasuswa ukuze ziphinde zisetshenziswe.Kodwa-ke, isiphetho sangempela sezingcezu azicaci: abanye bathi ziphonswe eMfuleni iThames noma zaba yi-ballast emikhunjini ngoba azikwazanga ukutholwa.Isizathu siwukuthi ngaleso sikhathi zonke zazenziwa ngensimbi eyinsimbi, okwakunzima ukuyibuyisela kabusha, ngokungafani nenani lezinto zokwakha kanye nemiklamo etholakalayo namuhla.Kodwa-ke, umsebenzi wabo awukashintshi: ama-balustrade ahlinzeka ngokuvikeleka kwabagibeli futhi angaba yinto ebalulekile yesakhiwo.Kulesi sihloko, sizochaza indlela yokuhlonza nokuklama izinhlobo ezahlukene zamarayili ngokusekelwe ezintweni ezihlukahlukene ezitholakalayo.
Izinsimbi zokuphepha kufanele zifakwe eduze kwezindawo ezisengozini yokuwa, izitebhisi, amarempu, ama-mezzanines, amaphasishi, ama-balcony kanye nezintuba ezingaphezu kwesisodwa (ngokuvamile kusetshenziswa omaka ama-40 cm ukuphakama).Zitholakala yonke indawo emadolobheni ethu futhi azinakwa.Ngokuyisisekelo aqukethe izingxenye ezi-4 eziyinhloko: i-handrail, i-central post, ujantshi ongezansi kanye ne-main shaft (noma i-balustrade) futhi kufanele iqine futhi ihlale isikhathi eside.Ngezinketho eziningi ezitholakalayo namuhla, izinsimbi zingaxuba izinto, zibe ne-opaque, futhi zivumelane nezabelomali ezahlukene.Ngezansi sigqamisa ezinye zezinto ezingasetshenziswa ukwenza izingxenye ezahlukahlukene nezinhlobo zamarayili, konke okungatholakala kukhathalogi yomkhiqizo we-Hollande:
Uhlaka lwangaphandle lwe-balustrade lubaluleke kakhulu njengoba luyiphoyinti lehange eliyinhloko lesakhiwo.Lezi zingaba izindawo zokuhlala, amaphaneli angaphakathi nezinye izesekeli.
I-Lightweight, iqinile futhi imelana nokugqwala, i-aluminium iyisinqumo esivame kakhulu kumarayili.Lokhu kwaziswa kwenza kube nokwenzeka ukukhiqiza ezicijile ukuthi ukonga futhi kulula ukuyifaka.
Lapho unquma izinketho ezingcono kakhulu zephrojekthi ngayinye, kubalulekile ukucabangela ukuthi umgomo uwukunikeza ukubukeka kwemboni okwengeziwe noma ukufakwa kwezinga okuhlinzeka ngokubukeka okujabulisa kakhulu kwezakhiwo nobuhle.Noma, uma kube lula kuwumgomo, khetha ikhithi yokuhlanganisa i-handrail yesandla ye-ADA ethobelana ne-ADA.
Insimbi engagqwali inamandla futhi iqinile kune-aluminium, kodwa futhi ingaba inketho ebiza kakhulu.Ngaphezu kwalokho, ikuvumela ukuthi udale ukuxhumana okucashile phakathi kwezingxenye, kanye nokwenziwa okubonakalayo.
Njengenketho ye-aluminium, izibani ezihlehlisiwe zingafakwa kanye namaphaneli engilazi ngendlela ehlelekile futhi eshintshiwe, okunciphisa isidingo sezinto ezivundlile futhi kuvumele ukubonakala okwengeziwe kumasethi.
Yakhiwe ngamaphaneli engilazi aqinile, i-balustrade yengilazi ehlelekile inezicathulo ze-aluminium ezingaphandle futhi ingagqokwa ngensimbi engagqwali noma i-aluminium.Phezulu, izindawo zokubeka izikhali zitholakala ngamashaneli ayindilinga futhi amise okwe-U ezinhlobonhlobo zezinto kanye nokuqedwa, ngokhuni olukhethwa kakhulu.
Ingilazi nayo ingalungiswa iqonde ngezikulufo ukuze inikeze isibukeli umbono “wodonga lwengilazi”.
Ama-filler angaphinde athintwe yizici ezithile, ezichazwe ngezansi.Kwezinye izimo, isikhala esingaphansi kwe-handrail singase singabi nalutho ngokuphelele, njengezitebhisi ze-grandstand noma ngokumelene nodonga.Izinga le-opacity lingesinye isici esibalulekile kanye nokuphepha okungahlinzekwa yimpahla ngayinye noma isisombululo:
Inketho yendabuko kakhulu, izigaba eziqondile zihlukaniswe ngokulinganayo, zakha isigqi esiyingqayizivele esikhumbuza izibonelo ze-balustrade zakudala.Kuyisixazululo sezomnotho nesobuhle sanoma iyiphi iphrojekthi yokwakha.
I-Glass ilungele amaphrojekthi adinga ukubonakala okusebenzayo kanye nesistimu ehlakaniphile.Ingilazi ye-monolithic evame ukusetshenziswa kakhulu ingu-3/8 intshi ubukhulu, kodwa lokhu kungahluka.Eminye imithetho kanye neziphathimandla zidinga ingilazi epholile ukuba ifakwe i-laminated, inikeze ukuvikeleka okukhulu uma kwenzeka ukuphuka.Imibala ehlukahlukene nayo iyatholakala - esobala, edayiwe kanye ne-matte - kanye namaphethini wobuciko angasetshenziselwa ukuhlobisa.
I-Metal mesh ihlanganisa ukukhanya nomnotho.Amaphethini ayisikwele angu-2″ x 2″ yiwona ajwayeleke kakhulu, nakuba angase eze ngobunye osayizi kanye nomumo.Kulokhu, izinto ezivame kakhulu yi-carbon steel kanye ne-powder camera aluminium.
Amashidi anezimbobo anikeza ukukhanya okuthile kodwa anamathela ngokuqinile.Izinketho zamaphethini kuleli cala ziningi, zenziwe nge-carbon steel ene-electronic coating kanye ne-powder noma i-aluminium ehlanganiswe ngempushana enendawo evulekile enkulu engu-50%.
Amashidi e-polymer, avame ukubizwa ngokuthi amapulasitiki, anezakhi zamakhemikhali ezimbili ezijwayelekile.Ngokuvamile, amashidi e-acrylic aqinile kodwa anokumelana nomlilo okuphansi kune-PETG (i-polyethylene) egcwele amashidi.Zombili zibiza kakhulu kunengilazi, kodwa zingamelana okungenani nemithwalo yesakhiwo ewugqinsi engu-3/8 intshi uma ivikelwe ngokufanelekile kokuthunyelwe noma ezinsimbini.
Manje uzothola izibuyekezo kuye ngokuthi yini oyilandelayo!Yenza kube ngokwakho ukusakaza kwakho futhi uqale ukulandela ababhali bakho abayintandokazi, amahhovisi, nabasebenzisi.
