Amakholomu Ayindilinga vs Ayisikwele: Ukukhetha Okuma Kwezinsika Zokwakha
Ukukhetha phakathi kwamakholomu ayindilinga nayisikwele kuphakathi kwezinqumo ezibalulekile kakhulu ekwakhiweni kwamatshe okwakha. Ukuma kwekholomu kuthonya ukusatshalaliswa komthwalo wesakhiwo, umbono obonakalayo wendawo, ubunzima bokwenziwa, kanye nezindleko zephrojekthi iyonke. Amakholomu ayindilinga abe yiwona abusa ukwakheka kwezakhiwo zakudala kusukela emathempelini aseRoma kuya kuma-palazzo eRenaissance, kuyilapho amakholomu ayizikwele nama-pilaster avela njengezinto ezihlukile ekwakhiweni kwesimanje nokwesimanje. Ukuqonda ukuhwebelana kobuchwepheshe nobuhle phakathi kwalezi zinhlobo zekholomu kwenza kube lula ukucacisa okunolwazi.
Izici Zesakhiwo Sezinsika Zamatshe Eziyindilinga Nezikwele
Amakholomu ayindilinga asakaza imithwalo yokucindezela ngokulinganayo engxenyeni yawo eyindilinga, esusa amaphuzu okugxilisa ukucindezeleka okwenzeka emakhoneni amakholomu ayizikwele. Lokhu kusatshalaliswa kokucindezeleka okufanayo kuvumela amakholomu amatshe ayindilinga ukusekela imithwalo ephakeme kancane kunezinsika zesikwele zendawo eyindilinga efanayo. Ikholomu eyindilinga enobubanzi obungu-400mm (indawo engu-125,664mm²) ingasekela umthwalo wokucindezela ongaphezu kuka-8-12% kunekholomu yesikwele engu-355mm (indawo engu-126,025mm²) yokuphakama okufanayo, ikakhulukazi ngoba ukuma okuyisiyingi kugwema ukuphakama kokucindezeleka kwamakhona.
Amakholomu amatshe ayisikwele anikeza izinzuzo ekumelaneni okusheshayo kokusetshenziswa lapho imithwalo eseceleni ibalulekile. Ubuso obuyisicaba bamakholomu ayisikwele buhlinzeka ngezindawo zemvelo zokuthwala izinsimbi zokuxhumanisa kanye nokuhlangana kodonga, okwenza kube lula ukuxhumana kwesakhiwo ezakhiweni ezifakwe uhlaka.Amakholomu nezinsika zamatshe okwakhaekwakheni kwanamuhla kukhethwa kakhulu ngokusekelwe ezidingweni ezithile zesakhiwo kunokuba kube ngokwesiko kuphela.
I-Natural Stone Institute inikeza iziqondiso zokuklama izakhiwo zamakholomu amatshe ekusetshenzisweni kwezakhiwo, icacisa izilinganiso ezincane zokuncipha ezihluka phakathi kwejometri eyindilinga neyesikwele. Irediyasi ye-gyration yekholomu eyindilinga cishe inkulu ngo-13% kunekholomu yesikwele yendawo elinganayo, okuvumela amakholomu ayindilinga amade kancane ngaphambi kokuba ukugoba kube yinto ekhathazayo yokuklama.
Izindleko Zokukhiqiza Nokuqhathaniswa Kobunzima
Izindleko zokukhiqiza zihluka kakhulu phakathi kwamakholomu amatshe ayindilinga nayisikwele. Amakholomu ayindilinga adinga amathuluzi ayinkimbinkimbi kakhulu ngoba ubuso bawo obuyisicaba bungasikwa kusetshenziswa ama-bridge saw ajwayelekile kanye nemishini yokulinganisa imiphetho. Ikholomu yesikwele enemiphetho elula enezimbobo ezithambile ibiza kancane ngo-20-35% ukukhiqiza kunekholomu eyindilinga yendawo elinganayo, ikakhulukazi ngoba ukujika kwekholomu eyindilinga kudinga imishini ekhethekile ye-lathe kanye nesikhathi esengeziwe sokusetha.
Amakholomu amatshe ayindilinga adinga ukujikwa kwe-lathe noma ukujikwa kwe-CNC multi-axis. Ukujikwa kwe-lathe yendabuko kusalokhu kuyindlela engabizi kakhulu yokukhiqiza amakholomu ayindilinga ngobuningi, ngama-lathe amatshe esimanje angakwazi ukujikwa amakholomu afinyelela kumamitha ayi-6 ubude kanye nobubanzi obungu-800mm. Ukujikwa kwe-CNC kunikeza ukuguquguquka okukhulu kwamakholomu ayindilinga acijile, acijile, noma acijile e-entasis kodwa kwandisa isikhathi sokuhlela kanye nokugaya ngo-40-60% uma kuqhathaniswa nokujikwa kwe-cylindrical okuqondile.
Amakholomu amatshe okuhlobisa okusetshenziswa ngaphakathi nangaphandlebazuze ezindleleni zokwenziwa ezihlanganisiwe. Ifomu lesisekelo lisikwa kusetshenziswa indlela ephumelela kakhulu, kuyilapho izihloko nezisekelo zokuhlobisa zithola ukuqoshwa ngesandla noma nge-CNC kuye ngobunzima bemininingwane ecacisiwe. Le ndlela ilinganisela izindleko nezidingo zomklamo.
Ukubona Okubonakalayo Nokuxhumana Kwesikhala
Amakholomu ayindilinga nayisikwele adala okuhlangenwe nakho okuhlukile kwendawo. Amakholomu ayindilinga abonakala elula ngokubonakalayo kunobunzima bawo bangempela ngoba izindawo ezigobile zibamba ukukhanya ngemigqa echaza isimo ngaphandle kwemigqa yesithunzi enzima. Ekholomu, amakholomu ayindilinga adala isigqi sokukhanya okushintshanayo kanye nesithunzi njengoba ababukeli behamba esikhaleni, kanye negebe elibonakalayo phakathi kwamakholomu lishintsha njalo.
Amakholomu ayisikwele abonisa ukuba khona okuqinile. Ubuso bawo obuyisicaba namakhona abukhali kudala imigqa yesithunzi ecacile egcizelela ukuma mpo nokucaca kwesakhiwo. Ekwakhiweni kwezakhiwo zesimanje, amakholomu ayisikwele namaphaneli e-pilaster aqinisa ukuhleleka kwejometri.Amaphaneli e-pilaster okuhlobisahlanganisa isisindo esibonakalayo sezinhlobo zesikwele nokulungiswa kwendawo yokuhlobisa, uhlanganise izilimi zokuklama zakudala nezanamuhla.
IUcwaningo Lwezemvelo lwase-USIzibalo zamatshe obukhulu zibonisa ukuthi cishe ama-65% amakholomu amatshe okwakha achazwe eNyakatho Melika ayindilinga, kuyilapho amakholomu ayizikwele kanye nama-pilaster ebusa amaphrojekthi okuvuselela aseYurophu lapho izinhlobo zama-pilaster zakudala zivame khona ezakhiweni zomlando.
Ukulinganiswa Kwe-Classical Order Yamakholomu Ayindilinga
Ama-oda okwakha akudala achaza izilinganiso ezithile zamakholomu eziye zaqondiswa umklamo iminyaka engaphezu kwezinkulungwane ezimbili. Uhlelo lwe-Doric luchaza ukuphakama kwamakholomu njengokuphindwe ka-4-7 kunobubanzi obuphansi. Amakholomu e-Ionic aphakama abe amadayamitha angu-8-9, kanti amakholomu aseKorinte afinyelela amadayamitha angu-9-10. Lezi zilinganiso zisebenza ngqo kumakholomu ayindilinga, okwakuyindinganiso ekwakhiweni kwezakhiwo zamaGreki namaRoma. Amakholomu asikwele ezimweni zakudala avame ukuphathwa njengezinsika ezinamathele odongeni kunezinto zesakhiwo ezizimele.
Ukufutha amakholomu kuthinta kakhulu isimo sokubonakala kwamakholomu ayindilinga. Ukufutha—imifantu eqondile esikwe emshaft wekholomu—kunezela ukuthungwa okubamba ukukhanya futhi kugcizelele ukuma mpo. Amakholomu e-Doric ngokuvamile anemifantu engu-20 ehlukaniswe yizinsika ezibukhali, kuyilapho amakholomu e-Ionic ne-Corinthian enemifantu engu-24 ehlukaniswe yizinsika ezisicaba. Ukufutha kunezela u-15-25% esikhathini sokwenziwa kwamakholomu ayindilinga futhi kudinga amathuluzi anembile ukuze kulondolozwe ukujula komfantu okuhambisanayo kanye nesikhala phakathi kobude bekholomu.
II-ASTM C1721indinganiso inikeza izinqubo zokuqinisekisa ukunemba kobukhulu bezinto zokwakha eziqoshiwe, kufaka phakathi i-geometry ye-fluting yamakholomu. Amaphrojekthi achaza amakholomu ane-flute kufanele afake izinqubo zokuqinisekisa esigabeni sokuklama ukuqinisekisa ukujula kwe-flute, ububanzi, kanye nesikhala kuhambisana nokubekezelelana okucacisiwe.
Ukukhethwa Kwekholomu Eqondene Nohlelo Lokusebenza
Umongo wephrojekthi uvame ukunquma ukukhethwa komumo wekholomu. Ama-portico okungena kanye nama-facade angaphambili kwethempeli adinga amakholomu ayindilinga ukuze kube yiqiniso lakudala. Amakholomu angaphakathi e-lobby ezakhiweni zezentengiselwano avame ukusebenzisa amafomu ayizikwele ukuze kube lula ukuhlanganiswa nezingxenye zodonga kanye nezinhlelo zodonga lwamakhethini engilazi. Amaphrojekthi ezindlu zokuhlala ahlukaniswa ngokulinganayo phakathi kwamakholomu ayindilinga nayisikwele, kanti amakholomu ayindilinga akhethwa ngezisekelo ze-portico ezimele kanye nama-pilaster ayizikwele achazwe ngezinhlelo ezihlanganisiwe odongeni.
Izidingo zesakhiwo nazo ziqondisa ukukhetha. Amakholomu asekela imithwalo yamaphuzu avela emishayweni engenhla—njengasezindaweni zebhizinisi ezivulekile—asebenza kangcono njengezingxenye eziyindilinga ngoba asabalalisa umthwalo ngokulinganayo. Amakholomu achaza amakhona egumbi noma izihlanganisi zodonga ngokwemvelo afanelana namaphrofayili esikwele ngoba ubuso besikwele buhambisana nezinhlaka zodonga eziseduze.
Amakholomu amatshe emvelo okwakhiwakungachazwa ngefomethi eyindilinga noma yesikwele ngokubala okufanele kobunjiniyela bezakhiwo. Ukukhetha phakathi kwezimo ekugcineni kuncike olimini lwezakhiwo, umthwalo wesakhiwo, kanye nemingcele yesabelomali yephrojekthi ngayinye ethile.
Izinto Okufanele Uzicabangele Zokufaka Izimo Ezihlukene Zekholomu
Izindlela zokufaka ziyahlukahluka phakathi kobunjwa bekholomu. Amakholomu ayindilinga adinga ama-shim agobile kanye nezihlalo ezisekelweni ukuze kuvinjelwe ukulayishwa kwetshe. Amakholomu ayindilinga amukela amapuleti ajwayelekile okuthwala ayisicaba kanye nemininingwane yokuxhuma elula. Kumakholomu azimele, amakholomu ayindilinga avame ukwakhiwa ngokufakwa kwesikhashana ukuze kugcinwe ukuhambisana okuqondile kuze kube yilapho ukuxhumeka okuhlala njalo kuqediwe. Amakholomu ayindilinga azivumelanisa kalula ngoba ubuso bawo obuyisicaba buhlinzeka ngezindawo zokubhekisela zokuqinisekisa i-plumb.
Zombili izimo zekholomu zidinga izisekelo ezenzelwe indlela ethile yomthwalo. Izisekelo zekholomu eziyindilinga ngokuvamile ziyindilinga noma ziyi-octagonal, zihambisana nephrofayili yekholomu. Izisekelo zekholomu eziyizikwele zisebenzisa izinyawo eziyizikwele noma eziyi-rectangular ezihlanganiswa kalula nezinhlelo zesisekelo eziseduze. Izindleko zesisekelo zokusekela imithwalo efanayo ziyafana phakathi kwezimo.
imibuzo ejwayelekile ukubuzwa
Yikuphi okubiza kakhulu ukwakhiwa: izinsika zamatshe eziyindilinga noma eziyizikwele?
Amakholomu amatshe ayindilinga abiza ngaphezu kwamakholomu ayizikwele alinganayo ngo-20-35% ngenxa yezidingo zemishini ekhethekile ye-lathe kanye nezikhathi zomshini ezinde. Amakholomu ayizikwele ane-flute anezela amanye u-15-25% ezindlekweni zokukhiqiza. Amakholomu ayizikwele angakhiqizwa ngemishini ejwayelekile yokusaha amabhuloho, okunciphisa izindleko zokusetha kanye nezokukhiqiza.
Ingabe amakholomu asikwele angasekela imithwalo efanayo namakholomu ayindilinga?
Amakholomu ayindilinga endawo elinganayo yesigaba esinqamulayo asekela imithwalo yokucindezela ephezulu ngo-8–12% ngenxa yokusatshalaliswa kokucindezeleka okufanayo. Kodwa-ke, amakholomu ayizikwele anikeza ukumelana okungcono kwesikhashana kwemithwalo eseceleni. Ezinhlelweni eziningi zokwakha, zombili izimo zingaklanywa ukuze zihlangabezane nezidingo zesakhiwo ngokulungisa ubukhulu besigaba esinqamulayo ngokufanele.
Kungakanani ukuphakama okuphezulu kwekholomu yetshe enengxenye eyodwa?
Amakholomu amatshe anesiqeshana esisodwa ngokuvamile anqunyelwe kumamitha ayi-6 ngobukhulu bebhulokhi yenkali kanye nemikhawulo yokuhamba. Amakholomu amade kunamamitha ayi-6 adinga amadrama ahlanganisiwe anezikhonkwane eziphakathi noma ama-dowel axhumanisa ingxenye ngayinye. Ingxenye ngayinye yamadrama isikiwe ukuze ifane nezingxenye eziseduze kusetshenziswa imishini yokulinganisa ye-CNC.
Ingabe amakholomu anezimbobo kunzima ukuwanakekela kunezimbobo ezibushelelezi?
Amakholomu athambile aqoqa uthuli kanye nokungcola kwemvelo emifuleni, okudinga ukuhlanzwa okuningiliziwe. Isinamathiseli sebhulashi elithambile ohlelweni lokuwasha olunomfutho ophansi sihlanza kahle izindawo ezithambile ngaphandle kokulimaza itshe. Amakholomu athambile awathinti ubuqotho besakhiwo futhi empeleni angafihla ukuguguleka okuncane kwendawo kangcono kunezinsika ezibushelelezi ezicwebezelayo.
Ingabe izinsika eziyindilinga noma eziyisikwele zisebenza kangcono ngezinhlelo zokumboza amatshe?
Amakholomu ayisikwele ayamukela ukumbozwa kwamatshe kalula ngoba ubuso obuyisicaba ngabunye bungambozwa ngamaphaneli amatshe ajwayelekile anamathele ngama-engeli okusekela avamile. Ukumbozwa kwamakholomu ayindilinga kudinga amaphaneli amatshe agobile noma izingcezu zokumbozwa ezihlukaniswe ngezigaba ezandisa ubunzima bokwenziwa futhi zibize ngo-30-50% uma kuqhathaniswa nokumbozwa kwamakholomu ayizikwele.
Yiziphi izinhlobo zamatshe ezivame kakhulu kumakholomu ezakhiwo?
Imabula kanye ne-limestone yizinto ezivame kakhulu zokusetshenziswa ngaphakathi. I-granite ithandwa kakhulu kumakholomu angaphandle abhekene nesimo sezulu. I-Crema Marfil limestone ithandwa kakhulu kumakholomu esitayela sakudala ngenxa yombala wayo ofudumele wekhilimu kanye nokuthungwa okuhlala njalo. Ukuze kuqedwe kahle kakhulu, amamabula e-Statuario kanye ne-Calacatta avame ukucaciswa.
