Upapashe uphando malunga neepateni zokunxiba izixhobo ekuchweni amatye kwiJournal of Materials Processing Technology.
Izinto ezibalulekileyo ekufuneka ziqwalaselwe
- Ukuhonjiswa kwamatye ecawa kulungelelanisa iimfuno ezine zobunjineli ngaxeshanye: umthwalo wesakhiwo, ukumelana nomlilo, ukhuseleko lomgangatho, kunye nokuziphatha kwesandi.
- Izibingelelo zemabula, iintsika zamatye eziqingqiweyo, kunye nemifanekiso eqingqiweyo yomgangatho zenza umsebenzi wamatye oqhelekileyo wangaphakathi kwecawa, nganye inendlela yayo yokwenza izinto.
- Ukugcinwa kwamatye eecawa zembali kulandela imigaqo epapashweyo, apho iGetty Conservation Institute kunye ne-ICCROM zibeka imigangatho esebenzayo.
- ICathedral yaseCologne ithathe iminyaka engama-632 ukugqitywa, kwaye iSagrada Família ibisakhiwa ukusukela ngo-1882 — iiprojekthi zamatye ezilinganiswe ngezizukulwana.
- Kwimigangatho yecawa, ukugqitywa okucociweyo, okuxutyiweyo, okanye okutshisiweyo kukhethwa kunepolish ekhazimlayo kuba ukumelana nokutyibilika okumanzi kubaluleke ngaphezu kokukhanya.
Kutheni Ilitye Libalulekile Kwimihombiso Yeecawa Noyilo Lwezakhiwo Ezingcwele
Ilitye lelona litye linxulunyaniswa kakhulu nengcwele kwizakhiwo zaseNtshona. Ukususela kwiibasilica zamaRoma ukuya kwiicathedral zaseGothic, iindonga ezithwele imithwalo, iintsika, imigangatho, kunye nee-altare zakhiwa ngalo, kwaye izizathu azizange zibe yinto yobuhle kuphela. Ilitye lithwala ubunzima, limelana nomlilo, kwaye - ngokubalulekileyo kwindawo yokunqula - litshintsha indlela isandi esiziphatha ngayo. Icawa egqunywe ngemabula kunye nelitye lekalika ayibonakali yahlukile kwiholo yeenkuni; ivakala yahlukile, ivakala ipholile ehlotyeni, kwaye imele iinkulungwane. Loo mxube wokusebenza ngokomzimba kunye nomfuziselo yinto umhombiso welitye lecawa ozimisele ukuyilungisa.
Ibhulukhwe yecawa yahlukile kuyo nayiphi na ihotele okanye indawo yokuhlala. Amabandla alindele ukuqina okulinganiswa kwizizukulwana ngezizukulwana, ukugqitywa okungakhanyi phantsi kokukhanya kwekhandlela, imigangatho ehlala ikhuselekile xa izihlangu zasebusika zibonakala kwikhephu, kunye nomhombiso oxhasa inkonzo yonqulo endaweni yokukhuphisana nayo. Le miqobo inciphisa ipalethi yezinto kwaye ilola iimfuno zobungcali, yiyo loo nto iiprojekthi zecawa zihlala ziyinxalenye enzima kushishino lwamatye.
Iimfuno ezikhethekileyo zokuhombisa amatye ecawa
Ukuyila ilitye lecawa kuthetha ukuyila umthwalo, ukhuseleko, isandi, kunye nokugcinwa ngaxeshanye. Iimfuneko ezine zilawula yonke inkcazo yelitye lecawa, kwaye zifanele ukuhlolisiswa ngokulandelelana.
Ukunyaniseka kwesakhiwo: Iikholamu zamatye, ii-Arches, kunye neendlela zomthwalo
Iicawa zigxininisa amatye anzima kwiikholamu, ii-arches, kunye nodonga olugqunywe yintsimbi. Ikholamu eqinileyo yemabula enobude obuyi-3 m kunye nobubanzi obuyi-300 mm inobunzima obumalunga ne-570 kg kubuninzi bemabula obuqhelekileyo obumalunga ne-2,700 kg/m³ — isikhumbuzo sokuba yonke into ethe nkqo sisigqibo solwakhiwo. Iikholamu zinokuba ze-monolithic okanye zihlanganiswe ngamacandelo anee-dowels zentsimbi engagqwaliyo kunye ne-epoxy; iiphaneli zogqunywe zisebenzisa ii-anchors ezimelana nokugqwala ezinobukhulu ngokwendlela yolwakhiwo. Kwimimandla yenyikima, iibrakethi zokuthintela kunye namalungu okunyakaza ayimfuneko, kuba amandla oxinzelelo lwelitye (ngesiqhelo ukusuka kwi-7,000 ukuya kwi-15,000 psi kwimabula nganye kwi-ASTM C170) adlula kakhulu amandla alo okuxinana — ilitye linamandla ekuxinaniseni kodwa libuthathaka xa ligoba.
Ukumelana nomlilo kunye nokhuseleko lomgangatho kwiindawo zokukhonza zikawonke-wonke
Ilitye lendalo alitshi, kwaye uninzi lwamatye lufumana amanqaku okusasazeka kwelangabi leKlasi A phantsi kwe-ASTM E84, uphawu lokulinganisa lwezixhobo zokwakha eMntla Melika. Oko kwenza ukuba kube lukhetho lwendalo kwiicawa apho amakhandlela, isiqhumiso, kunye neenkqubo zombane ezindala zihlala khona. Umgangatho yingxaki eyahlukileyo: iipaseji kunye nee-narthexes zibona izihlangu ezimanzi kunye nezithuthi ezininzi. Ii-specifiers zihlala zifuna i-wet dynamic coefficient ye-0.42 okanye ngaphezulu, elinganiswa ngokwe-ANSI A326.3, ekhomba ukugqitywa okucoliweyo, okubhrashiweyo, okanye okuvuthayo endaweni yokupholisha okukhazimlayo kwiindawo zokujikeleza kwegazi.
I-Acoustics: Indlela Ilitye Elibumba Ngayo Isandi Sendawo Engcwele
Ilitye libonakalisa isandi; icawa enkulu yelitye sisixhobo se-acoustic ngokwayo. Amaxesha okuphindaphindwa kwesandi semizuzwana emihlanu nangaphezulu alinganiswa rhoqo kwiicawa ezinkulu, yiyo loo nto umculo we-plainsong kunye nomculo we-organ waphuhliswa ngendlela efanayo. Isiphumo soyilo kukulinganisela: ilitye lomgangatho kunye neekholamu, kodwa umthi, ilaphu, kunye neplasta yee-pews, ii-silingi, kunye neepaneli zodonga apho kufuneka khona ukufunxwa. Ii-inlays ze-mosaic kunye neepaneli eziqoshiweyo zongeza ingqwalasela ebonakalayo ngaphandle kokutshintsha uhlahlo lwabiwo-mali lwe-acoustic.
