Guhitamo neza ibyuma bigena uburyo inyubako izaba ikomeye, ifite umutekano, kandi ihendutse. Ibishushanyo by'ibyuma bifasha ububiko, inganda, ibiro, ndetse n'amazu muri iki gihe. Buri mushinga ukeneye igishushanyo mbonera gihuye n'ingano yawo, imikorere yawo, n'aho uherereye. Guhitamo nabi bishobora kongera ikiguzi cyangwa bigatuma umutekano ugabanuka. Ariko, igishushanyo mbonera cyiza kirushaho kunoza imikorere kandi kikagabanya igihe mu gihe cy'ubwubatsi.
Gusuzuma byimbitse ibisabwa
Buri nyubako ifite intego itandukanye, kandi ibyuma bigomba guhuza n’iyo nshingano. Ahantu ho gukorera ibikoresho by’inganda hakenera ibiti bikomeye kurusha ahandi hantu hacururizwa ibicuruzwa hato. Urugero, ububiko bukunze gukoresha ibyuma binini kugira ngo bigire umwanya munini wo hasi. Urwego rudafite uburebure bwa metero 30 rutuma byoroha kugenda nta nkingi z’imbere. Mu buryo bunyuranye, inyubako y’ibiro ishobora gukoresha uburebure buto kuko ibice bigabanya umwanya.
Imiterere y'ibidukikije nayo igira ingaruka ku guhitamo. Inyubako yo ku nkombe ikenera icyuma kidatwarwa n'ingufu, mu gihe ahantu humutse mu gihugu imbere hashobora gukoresha ibyuma bisanzwe. Urugero, kubaka uruganda rutunganya amafi yo mu nyanja bisaba kwitabwaho mu kurwanya ingese. Gukoresha icyuma gikozwe mu cyuma cya galvanised cyangwa gutera irangi rirwanya ingese bishobora gutuma inyubako imara igihe kirekire.
Urukuta rugomba kandi guhuza n'ikoreshwa ry'inyubako mu gihe kizaza. Niba bishoboka ko inyubako yagurwa, inyubako z'icyuma zikozwe mu buryo bwa modular zituma byoroha kuyigura. Gusobanura icyo izakoreshwa hakiri kare bifasha kwirinda ikiguzi cyo kuvugurura imiterere yayo no kwemeza ko inyubako ihura neza n'ibikenewe ubu n'ejo hazaza.
Hitamo Ubwoko Bwiza bwa Karemu
Ubwoko butandukanye bw'amakaramu bugira intego zitandukanye zo gushushanya. Itatu ikunze kugaragara cyane ni amakaramu akomeye, amakaramu y'inkingi, n'amakaramu y'irembo.
Urukuta rukomeye rutanga ubudahangarwa bukomeye mu kunama. Rukwiriye inganda n'ububiko buhura n'umuyaga mwinshi cyangwa urubura rwinshi. Ibi ni ingenzi cyane mu bihugu nk'Uburusiya na Kanada bikeneye guhangana n'ubukonje n'ikirere kibi igihe kirekire.
Urukuta rw'imitako rukoresha ibice by'impandeshatu kugira ngo rukwirakwize imizigo neza. Rukora neza ku bisenge binini nko mu nzu z'imikino cyangwa mu byumba by'imurikagurisha. Urukuta rw'imitako rushobora kwaguka metero 50 rukoresheje icyuma gito ugereranyije n'igiti gikomeye, bigabanura ikiguzi cy'ibikoresho ho 15%.
Urukuta rw'irembo ni rwiza ku nyubako ziciriritse z'inganda. Ruhuza uburyo buhendutse kandi bwihuse bwo guteranya. Ahantu ho kubika ibintu bikonje hakoreshejwe urukuta rw'irembo rwa metero 25 hashobora kurangiza inyubako yarwo mu minsi 30.
Tekereza ku rwego rw'ibikoresho n'ubwiza bwabyo
Ibyuma byose si ko bifite imbaraga zimwe. Ingano y'ibikoresho igira ingaruka ku bushobozi bwo gukurura, kuramba, n'igiciro. Ingano y'ibyuma bisanzwe birimo Q235, Q345, na ASTM A36. Q235 ikwiranye n'inyubako zoroheje nk'amazu mato, mu gihe Q345 ishyigikira imitwaro iremereye nk'inyubako z'amagorofa menshi.
Urugero, igorofa ry'amagorofa abiriicyumba cy'imurikagurisha cy'icyumayakoresheje icyuma cya Q345B kandi yageze ku mbaraga zirenga 20% hamwe n'ingano y'umurambararo nk'iya Q235. Imbaraga z'umusaruro wa Q345 ni hafi 345 MPa, ugereranije na 235 MPa kuri Q235, bivuze ko ishobora kwihanganira imitwaro iremereye mbere yo kugonda.
Igenzura ry'ubuziranenge mu gihe cyo gukora naryo ni ingenzi. Ibyuma bifite imiterere idahuye cyangwa gusudira nabi bishobora kwangirika bitewe n'imbaraga. Buri gihe hitamo ibikoresho bifite icyemezo cy'inganda n'amakuru y'igenzura ry'umuntu wa gatatu. Irangi rya galansi cyangwa irangi ryongerera uburinzi ingese, cyane cyane ku nyubako zo hanze.
Suzuma Imitwaro n'Ishusho y'Imiterere
Ikomeyeurukiramende rw'icyumabagomba gutwara imizigo yose iteganijwe mu mutekano. Injeniyeri zibara imizigo yapfuye, imizigo mizima, n'imizigo ikomoka ku bidukikije nk'umuyaga cyangwa urubura. Umuzigo wose ugena ingano y'umuraba, intera y'inkingi, n'ubwoko bw'ingingo.
Urugero, ububiko bubika imashini ziremereye bushobora gukenera inkingi buri metero 8, mu gihe ububiko bworoheje bushobora kuzitandukanya na metero 12. Inyubako iri ahantu hahuha cyane ishobora gukenera ibice binini cyangwa ibikoresho by'inyongera.
Ikosa rito mu kubara imizigo rishobora gutera guhindagurika cyangwa guhindagura. Ahantu hamwe ho kubaka hagabanyije intera iri hagati y’inkingi kuva kuri metero 12 kugeza kuri 10 nyuma yo kwigana, hagaragaye ko imirabyo myinshi yari irimo umutwaro wose. Iri hinduka ryarushijeho kunoza umutekano hatabayeho kongera ikiguzi kinini.
Porogaramu zigezweho nka Tekla cyangwa STAAD.Pro zifasha gupakira neza imashini. Uburyo bwa 3D bwo gupakira butuma imashini ihura n’ibibazo hakiri kare, bigabanye ivugururwa ry’imashini aho ikorera. Gahunda nziza yo gupakira imashini ituma imashini ikora neza mu gihe cy’imyaka myinshi mu buryo bwose.
Ibande ku gishushanyo mbonera n'uburyo bwo gukora itumanaho
Imiyoboro ihuza imirasire, inkingi, n'imigozi. Imiyoboro mibi ishobora kwangirika nubwo ibice by'ingenzi byaba bikomeye. Abashushanya bahitamo hagati y'imiyoboro ihambiriye n'imigozi ihambiriye hashingiwe ku mushinga.
Imiyoboro y'ibyuma irahuze kandi yoroshye kuyishyiraho, ikaba ari nziza ku nyubako zabanje gukoreshwa. Yemerera ibice gusimburwa cyangwa guhindurwa aho byakorewe. Urugero, icyumba cy'ibyuma cyabanje gukoreshwa muri Vietnam cyakoresheje imiyoboro y'ibyuma kandi cyarangiye gushyirwaho vuba 20%.
Imiyoboro ishongeshejwe itanga imbaraga nyinshi kandi ikagira ubukana bwiza ariko ikeneye abakozi b'abahanga. Ikwiranye n'inyubako zihoraho nk'ibiraro cyangwa inganda nini.
Kugenzura ubuziranenge mu gihe cyo gukora birinda ibibazo by'ejo hazaza. Imyobo idahuye neza cyangwa imashini zidakoresha neza bigabanya ubushobozi bwo gutwara. Gukoresha imashini zikoresha ikoranabuhanga mu gukata no gucukura bituma habaho ubuziranenge. Nyuma yo gukora, ubuso bugomba guhabwa irangi rirwanya ingese cyangwa galvanisation.
Tekereza ku giciro, imikorere myiza, no ku buryo burambye
Igiciro bigira uruhare runini mu guhitamo amakaramu, ariko amahitamo ahendutse si yo meza buri gihe. Igishushanyo cyiza kizigama amafaranga haba mu bwubatsi no mu mikorere. Amakaramu yoroheje y'icyuma agabanya ikoreshwa ry'ibikoresho kandi yihutisha guteranya. Urugero, uruganda rukoresha imirasire yoroheje ya H rugabanya ikoreshwa ry'icyuma cyose ho 18% rutaratakaza imbaraga.
Gukoresha neza ingufu nabyo ni ingenzi. Icyuma kigaragaza ubushyuhe kandi gishyigikira uburyo bwiza bwo gukingira, kikagabanya amafaranga y'ingufu. Icyuma cyasubiwemo ni amahitamo adahungabanya ibidukikije kuko 90% by'icyuma gikozwe mu nyubako gishobora kongera gukoreshwa cyangwa kongera gukoreshwa.
Gutegura ibyuma nabyo birafasha. Ibikoresho by'icyuma bikorerwa mu ruganda bigabanya imirimo yo kubaka kandi bigagabanya igihe cyo kubaka. Ugereranyije n'inyubako gakondo, igihe cyo kubaka ikigo cy'ibikoresho gifite uburebure bwa metero kare 5,000 gishobora kugabanywaho amezi abiri.
Mu gihe uteganya ikiguzi, shyiramo ibintu by'igihe kirekire nko kubungabunga, kuvugurura irangi, no kuzigama ingufu. Urukuta rw'icyuma rurambye kandi rukora neza rutanga agaciro kurusha ubundi buryo buhendutse bwananirana hakiri kare.
Gahunda yo kubungabunga no kuramba
Igishushanyo cyiza kinareba uburyo bwo gukomeza gukomera kw'urubaho uko igihe kigenda. Igenzura n'isukura buri gihe birinda ingese no kwangirika. Gusiga irangi cyangwa gushyira ibyuma mu cyuma birinda ubushuhe n'imiti. Mu turere two ku nkombe z'inyanja cyangwa dukonje, kongera gusiga irangi buri myaka itanu bituma inyubako ikomeza kuba nziza.
Igishushanyo mbonera cy'imiyoboro y'amazi kirafasha. Ibisenge n'imigozi bigomba gukumira amazi yiyongera. Ikidendezi gito cy'amazi gishobora gutera ingese mu mezi make. Mu ruganda rumwe, gusimbuza imigozi irambuye n'ifite imigozi bigabanya ikiguzi cyo gusana ingese ho 30%.
Imigozi n'ingingo bikenera gukomezwa buri gihe, cyane cyane mu nyubako zihura n'ihindagurika. Gusuzuma imiyoboro y'amashanyarazi buri myaka ibiri birinda impanuka.
Guhitamo urufatiro rw'icyuma gikwiye ntibisaba imbaraga gusa. Abashushanya bagomba gutekereza ku ntego z'inyubako, ubwoko bw'urupapuro, urwego rw'ibikoresho, imitwaro, n'uburyo bwo kuyitaho. Ingero nyazo zigaragaza ko igishushanyo mbonera gikozwe mu buryo bw'ubwenge gishobora kugabanya ikiguzi, kugabanya gahunda, no kongera igihe cyo kubaho. Iyo uhisemo neza kandi ugashushanya, urufatiro rw'icyuma ntiruhinduka inyubako gusa, ahubwo ruhinduka umutungo w'igihe kirekire ku mushinga uwo ari wo wose w'inyubako.
