Yintoni efanele ibe amakhreyithi linyathelo phantsi lenkcenkce?

Ukuba ukhetha ukusebenzisa njenge athwale nophahla eziphathekayo metal, kuya kufuneka bafunde ngenyameko netheknoloji umsebenzi wofakelo, hayi kuphela nophahla, kodwa inkqubo sheathing.

Iimpawu ze ukubala

Inyathelo athwele phantsi metal kufuneka zikhethwe kunye esweni izinto ezimbalwa. Phakathi kwazo iintlobo nophahla, kubalulekile ukuba sinikele ingqalelo kwinkangeleko yakhe. Qiniseka ukuba bakuthathele ingqalelo indawo langutela phakathi izinto ezikufutshane ukuba akholisa echazwe imiyalelo kumenzi lwezixhobo. Ukuze ubone le parameter, kuyimfuneko ukuba balinganise umgama ukusuka ungqameko olungezantsi ebhodini yokuqala ukuya kwikona engentla owesibini. Inyathelo battens phantsi sentsimbi iza kuxhomekeka kwithambeka kwiziphambuka, kwaye ngeprojektha ububanzi kophahla aphesheya inkqubo starter bar.

Master kufuneka isigqibo phambi kokuqalisa imisebenzi, iza kuquka ukwakhiwa umsele, njengoko kuchaphazela izibalo. Ukuba idreyini yakho busisigxina kwibhodi ngaphambili, ngoko ukusa kwinqwanqwa kufuneka bongeze ngemilimitha-30. Phakathi kwezinye izinto, uya kwenza njengoko emdaka ngenxa yokukhupha amanzi, yaye ngokukodwa, ubukhulu bayo. Ngoko ke, ukuba ixabiso layo kuyalingana iimillimitha 90, lo Buze iya kwahluka kwimeko apho ilingana 120 iimilimitha. Umlinganiselo parameters uphahla projektha kufuneka kwenziwe ebhodini ngaphambili, le steepness of ithambeka kuya kuxhomekeka ekubeni indlela ukukhulula web metal. Ukuba wenza impazamo, oko esilimaza ukumiselwa indawo oluchanekileyo weMahalati. Kwesi sikhundla, izinto nophahla akayi izakhi weMahalati le nkqubo idibana.

Ukumisela umgama phakathi kwezakhi

Inyathelo athwele phantsi metal azakuchazwa kuthathelwa ingqalelo ubukho nezihlambo, imida lulinganiselwa kwaye wenze ukuyinyusa weMahalati kufuneka ibe ukusuka phezulu ukuya ezantsi, banikwe ubude nomsila nkqubo. Kwezinye iimeko, ngenxa yokuba ubukho nomsila elide kukho imfuneko ukufaka inkqubo kwibhodi sheathing engaphezulu, apho kuyimfuneko nitrogen ekugcinweni weMahalati ephakeme.

iimpawu obandayo

Phambi kokuqala umsebenzi, kufuneka ucinge apho iibhokisi inyathelo phantsi intsimbi baya kukhethwa. Okubalulekileyo, zeziphi izinto ziya kusetyenziswa. Ngoko ke, ukuba izixhaso emalifakwe umqadi candelo ngu 150 x 150 eemilimitha, nto leyo ke isalathiso ubuncinane, kodwa kufuneka isetyenziselwe sheathing imithi 25 x 100 iimilimitha. Kubalulekile ukuseka kuphela ikreyiti, kodwa kontrobreshetku, kufuneka usebenzise kwibhodi kunye necandelo cross-25 x 50 eemilimitha kuye. Umgama phakathi imiqadi kufuneka iyahluka ukusuka milimitha 600 ukuya 900. IBhodi lokuqala kufuneka abekwe kumgca othe ngqo ngaphaya wophahla, ngoko kuyimfuneko ukuba ukuthintela ukuba lwaqiniswa kunye tab.

ngeengcebiso zeengcali

Inyathelo battens phantsi metal kufuneka zikhethwe ukwenzela ukuba umgama ukusuka Inqwanqwa oluvelayo webhodi ukuya element elandelayo milimitha ngaphantsi kwama-50 xa kuthelekiswa nabanye, ngamanye amazwi, le parameter iyakulingana milimitha 300 okanye 400. Umgama phakathi ndima zilandelayo sheathing kufuneka ilingane phakathi amanqaku elikufutshane eliphezulu iprofayili inyathelo, ngamanye 350 no 450 iimilimitha. Inyathelo phakathi iibhodi sheathing iya kuba ilingane iimillimitha 350, Kwimeko ongasetyenziswayo kuyo lo mgaqo eze iibhodi yokuqala neyesibini. Hlalutya ukujonga indlela ngokuchanekileyo umgama phakathi Into yokuqala ekufuneka cwaka emhlabeni. Ukulungiselela le njongo, zimbini preform enxuseneyo kufuneka lumiswe kumgama othile, ukuba uvumelane ezinamanzi ze avala ngokwayo. ngoko ke enyanzeliswa phezu iithayile web oluya kugqiba ubude ifanelekileyo ezayo i yophahla.

iimpazamo engaba zikhona

Ukuba inqwanqwa weMahalati sele zichongiwe ngokuchanekileyo, kwaye le ndlela iza kuba elide kakhulu, oko kuya kukhokelela ekubeni amanzi ayikhukulise ngohlangothi emkhombeni, ngoxa amanzi mfutshane Buze kuya kumpompoza phakathi kumkhombe kunye nebhodi ngaphambili. Xa ingalo sheet unako gqitha phantsi ubunzima ikhephu. Ukuze afeze yophawulo, sebenzisa umlinganiselo tape. Emva kokuba kuyimfuneko ukulungisa isiphelo kunye ephakeme weMahalati. Wind umtya kufuneka ibekwe ngaphezu weMahalati. Ukuze kube lula ukomeleza ihashe, endaweni ilungelo kuba ingalungiseka ezongezelelweyo ibhodi yokulinganisa 25 x 100 iimilimitha.

UPawulos

Njengoko kwakusazeka, kunzima ukumisela umgama phakathi iziqalelo kwenkqubo yesakhelo. Yintoni kufuneka ibe phantsi inyathelo metal lathing, kufuneka uyazi, kuba ngenye inkqubo eliseluphahleni aziyi kwahluka ukuthembeka. Ngenxa yokuba iphepha elimisiweyo izinto nophahla kuyacetyiswa kwinxalenye lowermost lwamaza yayo, umgama phakathi amacandelo weMahalati kufuneka kukhethwe kuxhomekeke incochoyi izinto yabucala. Njengoko esifanele imilinganiselo umgangatho kunye amaza ezinqamlezayo metal ezivelileyo milimitha 300 no 450. Xa kubalwa imigama phakathi iibhodi lathing kukhokelwa ncam kulo mzobo.

Iimpawu ze sheathing

Inyathelo athwele phantsi tile metal "Monterrey" iya kuba ngokufanayo izinto yemveli. Phambi ekuveliseni umsebenzi eziyimfuneko ukwenza imilinganiselo umgama phakathi emiqadini. Ngenxa yoko, ubude ebhodini okanye iplanga, uya leyo isiseko weMahalati iya kulingana isalathisi oko kukuthi iphindaphindeke umgama phakathi emiqadini. Ukukhetha iinkuni nkqubo kufuneka abe okulindelekileyo ukuba yomile kakuhle iimeko zendalo, ngokunjalo buzane ngokugqibeleleyo kunye magciwane. izinto ezongezelelweyo kunokuba self-iphathwa kunye retardants ilangatye. Kuxhomekeke kuqwalaselo lwendlela yokusebenza, njengoko ekufanisweni sheathing kwi isandi lophahla degrees-15 ukuya kuma-60 kufuneka asebenzise ibhodi 24 x 100 iimilimitha. Langutela phakathi ezisekele kule meko kufuneka ilingane-1200 mm. IBhodi 36 x 100 mm kufuneka ingasetyenziswa xa umgama phakathi uphahla kwe 1200 eemilimitha. Oku kuyinyaniso kananjalo ukuba ityala xa metal esetyenzisiweyo, Ebubanzini leyo ilingana no 1.5 iimilimitha.

Xa athwele inyathelo phantsi nophahla metal "Grand Line" (okanye nayiphi na enye) imiselwa, uyakwazi ukuqhubeka kulwazi izinto. Ngoko ke, ukuba uphahla inophawu uqwalaselo mgaqweni, ukusetyenziswa nemivalo yayo milimitha-40 x 60. Kulo mzekelo, imiqadi ziya zipakishwe kunye linyathelo elibalulekileyo. Lathing kusenokuba yinto eqinileyo, usebenzisa ichipboard okanye ngamaplanga. Le nto ke kudityaniswe ikreyiti, wabumba bar. Le ngxelo kuyinyaniso kwiindawo esimbaxa nophahla, umz, iindawo yaxokomezela, uphahla, le kummango neentlambo. Calculation lathing inyathelo phantsi metal eveliswe ubuchwepheshe obufanayo, ukuba kusetyenziswa xa yabucala metal, onako ukubuyisela izinto ngamaplanga. Esi sigqibo bayagwetyelwa ngaye xa kukho imfuneko ukuphumeza iipropati zokukhusela umlilo eliphezulu kwinkqubo eliseluphahleni.

Ukubekwa isixa

Ukuba uya komelela phantsi ikreyiti metal, wenze into elungileyo, kubalulekile kakhulu. Kodwa kufuneka abale inani izinto. Ukuze benze oku, inani lemiqolo olunamandla lombane limele liphindaphindwe ngenani neebhodi kolu thotho, yaye emva omnye zambini. Ekugqibeleni, wena ufumane imali ilungelo amaplanga ekufuneka ndimzuzile ukuba enze weMahalati. Ngenxa yokuba amaplanga wathengisa, ngokuqhelekileyo ngezixa, inani iibhodi kufuneka ukuguqukela cubic metres. Ukulungiselela le njongo, imilinganiso zejiyometri apho zibonakaliswa ngeemitha, ukuba zande, kwaye iphinda phindiweyo ngo inani elithile iibhodi ukubala. Amanqaku uba ekukhethwa esima ezithile eziya kuba yimfuneko xa kuthe ukuba ezinye izinto ziya sinesiphene. Xa kufikwa uphahla yoqwalaselo esimbaxa, kufuneka kubalwe kwenziwe kwisiza ngasinye kwinkqubo eyahlukileyo.

Ekuphetheni

Chaza wena step amakhreyithi uyakwazi ukufunda inqaku, kodwa yinxalenye encinane nje impumelelo. Kuya kuba Kubalulekile ukwenza ilungelo lokufaka, elandela ubuchwepheshe. Kuphela ngale ndlela izibalo zichanekile, kwaye inkqubo uphela uya kuba amandla ezahlukeneyo nokuqina kwayo, kwakunye imbonakalo enomtsalane.
