Dulmar guud ee dib-dhaafka
Bargan birta ah ee ciribtirka birta ah waa tayo sare oo bir ah / loo isticmaalo la xoojiyey la taaban karo oo la xoojiyay dhismayaasha Masonry. Waxaa laga sameeyay bir khafiif ah oo waxaa la siiyaa feeraha si loo dhaco cufnaanta si ka fiican u taaban. Dhoolaca feeraha oo ay sabab u tahay doorka feeraha, iyo wax la taaban karo waxay leeyihiin awood weyn oo ku saabsan isku-darka, taas oo si ka sii adkaysata ciidamada dibada. Barxada birta ee cilladaysan waa bir bir ah, oo ah dib-u-habeyn buluug ah oo dhar ah, waxaana sidoo kale loo isticmaali karaa sidoo kale goos goos goos ah. Qaabka feeraha transvers waa mid wareegaya, herringbone, saddex-qambad ah. Miiraaca ugu sarreeya ee ciribtirka birta lagu xoojiyey ayaa u dhigma dhexroorkii ugu dambeeyay ee qadka wareega ee qaybta iskutallaabta. La xoojiyey la taaban karo ee walaaca ugu weyn ee walaaca weyn.

Noocyada dib-u-soo-dhafka
Waxay kuxirantahay nooca sheyga loo isticmaalo soosaarka Rebar, noocyada kala duwan ee soo-dhafka ayaa ah
l 1. Roobka Yurub
Rebar Bisadaha Yurub wuxuu ka kooban yahay manganese, kaas oo ka dhigaya inay si fudud u laabato. Iyagu kuma haboona isticmaalka aagagga u nugul xaaladaha cimilada ba'an ama saamaynta joqojiga, sida dhulgariirrada, duufaanta, ama tornaadooyinka. Qiimaha dib-dhaaradani wuu yaryahay.
l 2. Cayrta ceelka birta
Maaddaama magacu matalayo, waxay ka kooban tahay bir yar oo bir ah waxaana loo yaqaan sida ugu badan ee loo yaqaan 'madow' oo ay sabab u tahay midabka kaarboonka. Dib-u-dhac ugu weyn ee dib-dhaaradani waa in ay la jaanqaadato, taas oo si xun u saameynaysa la taaban karo iyo qaab dhismeedka. Saamiga xoogga xoogga leh ee leh ee lagu daray qiimaha ayaa dib u soo laabtay mid ka mid ah xulashooyinka ugu fiican.
L 3.
Dib-u-soo-celinta dharka lagu qodbay waa dib-u-dhaafis madow oo leh jaakad dhalo ah. Waxay leedahay awood isku mid ah, laakiin waa 70 ilaa 1,7 jeer oo u adkaysta hudheelka. Si kastaba ha noqotee, daboolka ephoxy waa mid aad u cajiib badan. Burburka weyn ee burburka dahaarka, ayaa hoos u dhigi u-adkaysi ilaa saxarada.
l 4. Galvanized Roobka
Rebarvanized Roobka ayaa kaliya afartan jeer u adkaysta xarkaha ka badan caloosha madow, laakiin way ku adag tahay in la dhaawaco dahaarka dib-u-soo-celinta. Ixtiraamkaas, waxay leedahay qiimo ka badan refab-ka-dhabarka ee 'Epoxy-Compay'. Si kastaba ha noqotee, waxay ku dhowdahay 40% ka qaalisan repar-ka-dhabarka ee 'epoxy-dahabka'.
L 5 galaas-fiber-fiber-polymer (gffp)
GFRP wuxuu ka kooban yahay capanbon-ka. Maaddaama ay ka kooban tahay fiber, fooraad lama oggola. Waa mid aad u adkaysata shixnadaha oo waa qaali marka loo barbar dhigo roobab kale.
l 6.
Bisha Steel Shil-galeen waa kan ugu qaalisan ee la heli karo, qiyaastii sideed jeer qiimaha dib-u-dhiska ee 'Epoxy'. Sidoo kale waa Rebar ugu fiican ee loo heli karo inta badan mashaariicda badankood. Si kastaba ha noqotee, adoo adeegsanaya bir bir aan caadi ahayn oo dhan laakiin waxa ugu gaarka ah duruufaha ugu gaarka ah badanaa waa isku xidhka. Laakiin, kuwa haysta sabab ay ugu isticmaalaan, oo ay biir ka dhigaan biir bayaan ah oo bir ah oo bir ah Waxay u adkeysaneysaa waxyeelada marka loo eego mid ka mid ah noocyada kale ee dib-u-adkeysta ama cadeynta ama dib-u-dhaafida-dib-u-celinta; Oo duurkana waa lagu qurxin karaa.
