Ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma nk’ibikoresho vy’ishimikiro. Ivyo bihimba vy’umubiri bifatanya aho bihuriye hakoreshejwe ibikoresho vy’ugusudira bikoreshwa n’ubuhinga bwa none. Hanyuma, igice c’ivyuma gikomeza gikorwa ku ruhande rw’urusenga biciye mu gutera ivyuma bishushe canke mu gutera ivyuma bikoresheje umuyagankuba kugira ngo haboneke igikoresho c’urusenga rw’icuma.
Umushinge w’uburyo bw’urusenga rw’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma. Ivyiyumviro vyose bishiraho ibipimo vy’ingenzi ku bikoresho, ivy’imiti, ivy’ubuhinga, n’ukuri kw’ingero z’urutsinga rw’icuma kugira ngo ntihagire ingorane nk’uguca ibice kw’urusenga rushobora gusenyuka, ugutandukana kw’ivyuma, n’ugusenyuka kw’ivyuma bitewe n’ibintu bitari vyiza. Ikozwe mu nsinga y’icuma y’agaciro kanini-y’agaciro gato -y’umuyagankuba, n’ibice vya Q195, Q215, na Q235 ni vyo bikundwa. Gukoresha ivyuma vyasubiwemwo n’ivyuma vy’ibisigazwa vy’agaciro gatoyi nk’ivyuma vy’imbere birabujijwe cane. Ivyo bihimba vy’umubiri birimwo bitegerezwa kugenzurwa cane, harimwo n’ivyo bita carbone, silikoni, manganese, sulfure na phosphore, kugira ngo bishobore gusudirwa, gukomera no gukomera. Ivyerekana vyihariye ni ibi: carbone Iri munsi canke ingana na 0,22%, silicon Iri munsi canke ingana na 0,30%, manganese 0,30%~0,80%, ikibiriti Iri munsi canke ingana na 0,045%, na phosphore Iri munsi canke ingana na 0,045%.
Ivyo bipimo vy’imiterere y’urusenga rw’ivyuma vy’agaciro biragira ico bikoze ku bijanye n’ugushiraho, ingaruka zo gukingira, n’ugushikama kw’imiterere, bikaba bituma biba ibintu nyamukuru vyo gusuzuma ukuntu bisa n’ingene bimeze. Hot-dip galvanized welded wire mesh iri mu zinc ku bushuhe bwinshi bwa 450℃~480℃, bikaba bituma haba igice c’ivyuma gikomeye gifise ubushobozi bwo kwifatanya cane kandi gishobora guhangana n’ugusenyuka, kibereye hanze, ahantu hari ubukonje, no mu bidukikije bishobora gusenyuka. Ku rundi ruhande, urusenga rw’umuyagankuba rwo mu bwoko bwa electro-galvanized welded wire mesh rufise igice c’ivyuma vy’umuyagankuba gishizwemwo ivyuma vy’umuyagankuba, ivyo bikaba bituma igice c’umuyagankuba gica gitoya cane, kikaba giteye neza, kandi kikaba gifise igiciro gito, kikaba gibereye gusa mu bibanza vyumye vyo mu nzu no mu gukingira umuco.
Igishushanyo nyamukuru c’urusenga rw’urusenga rw’urusenga rw’amabuye y’agaciro ni urusenga rw’insinga, rutanga ugushikama kw’imibumbe, ubushobozi bwo kwikorera umuzigo bumwe, n’ugusangira imibabaro mu buryo buringaniye, bibereye kwubaka, uburimyi bwo mu mazi, n’uburinzi bw’inganda. Diamond-shaped mesh itanga ubushobozi bwo guhinduranya cane n’ubukomezi bwo gukomera, bibereye gukingira umusenyi no guhinduranya uruzitiro. Ugukevya kw'urusenga kugira ingaruka zitaziguye ku kwuzuza ivu, gukingira ikibanza, no gushiramwo guhuza; rero, ukunyuranya kwemerewe mu bunini bw’urusenga ni ±0.5mm, kandi mu rupapuro rumwe rw’urusenga, ukunyuranya hagati y’ubunini bw’urusenga butatu bwose buri hafi gukwiye kuba Muto canke bingana na 0.3mm. Intsinga z’urudodo n’iz’urudodo zitegerezwa kujabuka zigororotse, intsinga z’urudodo zikaba zigoramye; skewed meshes zirabujijwe cane.
Ibisabwa kugira ngo umuntu agire uburinganire ku bijanye n’urusenga rw’intsinga rwo mu bwoko bwa Welded Galvanized birakomeye cane. Iryo senga ritegerezwa gushirwa ku ndege y’ishingiro iringaniye ifise uburebure bw’uruzitiro Buri munsi canke bungana na 20mm/m, kandi uguhinduka kwose kw’imipfunda canke kw’imipfunda kurabujijwe cane kugira ngo ahantu habe haringaniye. Intsinga z’urudodo n’iz’urudodo zitegerezwa kuba zihuye kandi zikaba zitandukanye; ntihakwiye kubaho intsinga zipfutse (intsinga zibiri), intsinga zivunitse canke intsinga zibuze. Inenge nk’intsinga zivunitse canke amabara atandukanye zikwiye kuba ziri munsi canke zingana na 2 ku 10m2 y’urusenga, kandi amabara yasanuwe ategerezwa kuba afise inkomezi n’ibisabwa vyo guhangana n’ugusenyuka.
Uburyo bwo gusudira ni umurongo w’ubuzima bw’imiterere y’urusenga rw’ivyuma, rugena ata guca ku ruhande inkomezi z’urusenga rwo gukomera, inkomezi zo gukemurwa, n’ubushobozi bwo guhangana n’ingaruka. Ivyiyumviro bisanzwe bishiraho ibimenyetso vy’ingenzi vy’inkomezi z’ugusudira n’utunenge two gusudira. Uburyo bwo gusudira bukoreshwa n’ubuhinga bwo guhangana n’ibintu, n’amasanganzira y’ibihimba vy’umubiri n’ibihimba vy’umubiri bikoreshwa hakoreshejwe ubuhinga bwo gusudira bushushe-bukoreshwa n’umuyagankuba. Ivyuma bifatanye bitegerezwa kuba bihuye, bikomeye kandi bitagira ivyuma bifatanye bidatunganye, bitagira amazi asohoka canke bitagira ivyuma bifata amazi. Igipande c’ibarabara gikwiye kuba 1.2~1.5 incuro z’igipande c’urutsinga, kandi uburebure bw’ibarabara bukaba buri munsi canke bungana na 0.2mm kugira ngo ntihagire ibintu biva hanze bigira ico bikoze ku buringanire bw’ibarabara. Zero amabuye y’ibinyoma na zero amabuye y’ibinyoma muri buri nzira ya 10m2, n’igipimo rusangi c’amabuye y’ibinyoma kiri munsi canke kingana na 0,1%, kandi bisabwa gusanurwa kugira ngo bihure n’ingingo mfatirwako. Igipande c’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma, umubare w’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma ni Muto canke ungana na 5% vy’umubare wose w’ibifungurwa vy’ivyuma, ubunini burengeye ubw’ivyuma vy’ivyuma vy’ivyuma bimwe ni Muto canke bungana na 10% vy’umurongo w’urutsinga, ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma vy’ivyuma, Irenga canke ingana n’ibice 95%.
Igipande c’ivyuma ni inzitizi y’ugusenyuka kw’ivyuma vy’ivyuma vy’ivyuma, kandi uburyo bwavyo ni bwo bugena ata guca ku ruhande igihe igikoresho kizomara. Ni igice nyamukuru c’ubugenzuzi mu ngingo ngenderwako z’uburyo, gifise ingingo ngenderwako zisanzwe zishinga ibimenyetso bishingiye ku bipimo bitanu: ukwifatanya kw’uruzitiro rwa zinc, uburemere, ukuntu rumwe, ukwifatanya, n’ukudashobora gusenyuka. Ugufatanya kw’uruzitiro rwa zinc guhuye ata guca ku ruhande n’uguhangana n’ugusenyuka, kandi ingingo ngenderwako zisanzwe zishinga ibisabwa vy’ingenzi ku bihe bitandukanye: Hot-dip galvanizing: Ibintu rusangi Birengeye canke bingana na 90g/m2, bikeyi vyo mu karere Birengeye canke bingana na 70g/m2; Electro-galvanizing: Ivyiyumviro rusangi Birengeye canke bingana na 30g/m2, igice gitoyi c’aho hantu Birengeye canke bingana na 20g/m2; Uburemere bw’igice ca zinc ni nk’ibice 7,2g/cm3. Igishushanyo co guhindura ni: Uburebure bw'uruzitiro rwa zinc (μm) ≈ Ukwifatanya kw'uruzitiro rwa zinc (g/m2) ÷ 7.2. Igipande ca zinc kigomba kubandanya, kimwe, ata n’aho kibura canke ivyuma bigaragara. Uburyo nyamukuru bwo kugerageza ni ubwo kugerageza kwibika mu mazi y’umuringa.
Uburyo bwo gupima uburemere bw’urusenga rw’ivyuma bishingiye ku nkingi zine z’ingenzi: ibikoresho vya mbere, uburebure bw’imibumbe, ubushobozi bwo gusudira, n’uburyo bwo gusudira. Ivuga ku bipimo vyose vy’igihugu, ivy’Uburayi n’ivy’Amerika, n’ivy’inganda, bikaba bikora uburyo bwo kugenzura uburyo bufunze-bufatanya uburyo rusangi n’uburyo bwihariye. Ku bahinga, ni ngombwa ko bakurikiza cane ingingo ngenderwako zisanzwe kandi bagakomeza ukugenzura uburyo mu gihe cose c’ivyo bikoresho. Ku baguzi n’abakoresha, birahambaye cane guhitamwo ibintu bihuye n’ingingo mfatirwako zishingiye ku bikenewe vyihariye, ugashira imbere ivyuma vy’umuringa vy’umuriro kugira ngo bishobore guhangana n’ugusenyuka kw’igihe kirekire. Kubera iterambere ry’inzego z’inganda n’ubwubatsi kw’isi yose, ingingo ngenderwako z’uburyo bw’urusenga rw’intsinga zizobandanya gutera imbere zija ku bushobozi bwo guhangana n’ubumara, ubukomezi bwinshi, ingingo ngenderwako z’ivyatsi bitotahaye, n’ugutunganya cane, kandi ukugenzura uburyo bw’ibicuruzwa bizobandanya gukomera kandi bihuye n’ingingo ngenderwako.
