Izikhonkwane eziKhuselekileyo: Iintlobo ezine ezibalulekileyo kunye nezicelo zazo
Ehlabathini le-fasteners, izikhonkwane zihlala zisinye sezona zisombululo eziguquguqukayo kunye nezisetyenziswa ngokubanzi. Ngaphezulu kwamashumi eminyaka kwishishini, ndiye ndafunda ukuba ukukhetha uhlobo oluchanekileyo lwezikhonkwane kunokwenza okanye kwaphule iprojekthi. Namhlanje, siza kugxila kwiintlobo ezine zezikhonkwane ezisisiseko ekufuneka ingcali nganye izazi kakuhle:Izikhonkwane eziqhelekileyo, izikhonkwane zokubumba, izikhonkwane zekhoyili, kunye nezikhonkwane ezineentloko ezimbini. Makhe sihlolisise iimpawu zabo ezizodwa, amandla, kunye neemeko ezifanelekileyo zokusetyenziswa ngokunzulu.
1. Izikhonkwane eziqhelekileyo: Umqolo woMsebenzi weZakhiwo
Izikhonkwane eziqhelekileyongamahashe okusebenza ehlabathi elikhawulezayo. Ibonakaliswe nge-shank engqingqwa, ethe tye kunye nencam emile njengedayimane, zigqwesa kwizicelo ezinobunzima apho amandla amakhulu abaluleke kakhulu. Uyilo lwabo olomeleleyo lubavumela ukuba bangene kwizinto ezishinyeneyo njengamaplanga ngaphandle kokugoba, nto leyo ebenza babe yimfuneko ekwenzeni iindonga, ukwakha iidesika, okanye ukudibanisa iipalethi zomthi. I-flat, intloko ebanzi inika indawo eyaneleyo yokukhusela izixhobo ngokuqinileyo, nangona ishiya uphawu olubonakalayo-into yokuqwalasela ukuba i-aesthetics ibalulekile. Ngelixa izikhonkwane eziqhelekileyo ziqhelekile ukuba zingagqunywanga (ukugqiba okuqaqambileyo), zinokufakwa igalati kwiiprojekthi zangaphandle ezinje ngocingo okanye ukwakhiwa kweshedi. Ukuguquguquka kwabo kunye nokufikeleleka kuqinisekisa ukuba baya kuhlala benendawo kwiindawo zemisebenzi.
2. Izikhonkwane zokuqulunqa: Ukuchaneka kuhambelana namandla
Ihlala ibhidaniswa nezikhonkwane eziqhelekileyo, izikhonkwane zokubumba zenzelwe ngokukodwa iimfuno zolwakhiwo lwangoku. Ezi zikhonkwane zibonakalisa i-shank ebhityileyo kancinci kwaye zihlala zidityaniswa zibe yimicu okanye iikhoyili ukuze zisetyenziswe ngemipu ye-pneumatic, zikhawulezisa kakhulu iiprojekthi ezinkulu ezinje ngefreyim yendlu okanye ufakelo lwetruss yophahla. I-angled okanye i-designed head design ivumela ukudibanisa okungqongqo, ukunciphisa i-jams kwi-nail guns. Izikhonkwane zokubeka kwakhona ziza kunye neengubo ezikhethekileyo (umzekelo, i-vinyl okanye i-epoxy) ukwandisa ukubamba kunye nokuthintela "ukuphuma" ekuhambeni kwexesha njengoko iinkuni zikhula kunye neekontrakthi. Iingcali ezijongana nezakhiwo ezenziwe ngamaplanga okanye ukufakwa phantsi komhlaba, izikhonkwane zokubumba zibetha ibhalansi egqibeleleyo phakathi kwesantya, ukubamba amandla, kunye nokuhambelana nezixhobo zamandla.
3. Izikhonkwane zekhoyili: UkuSebenza kwiiProjekthi eziPhezulu zoMqulu
Izikhonkwane zekhoyilingamagorha angazange adunyiswe wokuzilolonga okukumgangatho ophezulu. Idizayinelwe ukuba ilayishwe kwimipu yezikhonkwane, ezi zikhonkwane zifakwe kwimagazini ejikelezayo exineneyo, evumela ukuqhuba ngokukhawuleza, okuqhubekayo kunye nokulayisha okuncinci. Ngokuqhelekileyo zisetyenziselwa ukuphahla, ukujikeleza, kunye nokufakwa kwe-sheathing apho amakhulu ezikhonkwane kufuneka afakwe ngokukhawuleza. Uyilo olubhityileyo, olukhaphukhaphu lunciphisa ukudinwa ngexesha lokusetyenziswa okongeziweyo, ngelixa iintsimbi ezifakwe igalvanized okanye i-stainless steel finishes ziqinisekisa ukomelela ngokuchasene nokuba sesichengeni semozulu. Inzuzo ephambili yezikhonkwane zekhoyili kukuguquguquka kwazo: ubude obufutshane (i-1-2 intshi) umsebenzi wokudibanisa i-shingles, ngelixa iinguqu ezinde (ii-intshi ezi-3+) ziphethe i-sheathing enzima okanye ucingo. Ukuba iprojekthi yakho ifuna isantya ngaphandle kokuyekelela ekubambeni amandla, izikhonkwane zekhoyili zitshintsha umdlalo.
4. Izikhonkwane ezineentloko ezimbini: iNgcali yokuLungisa okwethutyana
Izikhonkwane ezinentloko ephindwe kabini, ezaziwa ngokuba zizikhonkwane eziphindwe kabini, zisisityebi kodwa sisixhobo esixabiseke kakhulu. Ngeentloko ezimbini ezihlukeneyo ecaleni kwe-shank, ziyilelwe izakhiwo zexeshana ezifana ne-formwork yekhonkrithi, i-scaffolding, okanye ufakelo lwamaxesha onyaka. Intloko ephezulu isebenza njengento yokumisa, ivumela ukuba isikhonkwane siqhutywe kuphela kwizinto eziphathekayo. Xa ilixesha lokuqhawula, intloko engezantsi inika ukubamba ukutsalwa, ukunciphisa umonakalo kwimithi enokuphinda isetyenziswe. Ezi zikhonkwane zihlala zishushu-zifakwe igalvanized ukuze zimelane nokuvezwa kwangaphandle ngexesha lezigaba zokwakha. Nangona kungesiso isisombululo esisisigxina, izikhonkwane ezineentloko ezimbini zigcina ixesha, zinciphisa inkunkuma, kwaye zigcine iiprojekthi zilungelelanisiwe-kufuneka zibe neekontraka ezilawula izakhiwo eziyinkimbinkimbi, ezininzi.
Ukukhetha okulungileyo Gqiba
Ngelixa uhlobo lwezikhonkwane lumisela umsebenzi, ukugqiba kumisela ubomi obude. Izikhonkwane eziqaqambileyo (ezingagqunywanga) zisuti ngaphakathi, iindawo ezomileyo ngenxa yexabiso eliphantsi kodwa ziyarusa ngokulula. Izikhonkwane ze-Electro-galvanized (EG) zinika umaleko we-zinc obhityileyo wokumelana nokufuma okuphakathi, okufanelekileyo kwiiprojekthi zangaphandle ezikhuselweyo. Kwiimeko ezinzima, izikhonkwane ezifakwe kwi-galvanized (HDG) ezishushu zibonelela ngekhuselo le-zinc elishinyeneyo, elimbhoxo, ngelixa izikhonkwane zensimbi engenasici zihambisa ukuxhathisa okungenakuthelekiswa nanto kwiindawo eziselunxwemeni okanye ezinobunzima bekhemikhali. Soloko uthelekisa ukugqiba kwiimfuno zokusingqongileyo zeprojekthi yakho.
