Isakhiwo ngasinye siqulunqwe ngamacandelo ahlukeneyo, kwaye umsebenzi ophambili wecandelo ngalinye ukwahluke kakhulu.Amacandelo ensimbi ngoku awona macandelo aphambili kwizakhiwo ezininzi zokwakha, kwaye izixhobo zentsimbi ezisetyenziswa kwiindawo ezahlukeneyo zidlala imisebenzi eyahlukeneyo.
Kwaye iiprojekthi yesakhiwo sentsimbiyamkelwe ngamazwe amakhulu emveliso.Uyilo lwebhayi enkulu ye-workshop yesakhiwo sensimbi, indawo encinci ye-cross-sectional yesakhiwo sensimbi, ukufakela kunye nokuthutha kukulungele, ixesha lokwakha lifutshane kunendlela yokwakha yendabuko, kwaye izinga lokusetyenziswa kwemali liphuculwe kakhulu. .kwaye usebenzise isantya.
Ukwakhiwa kwesakhiwo somzi-mveliso wentsimbi kubunjwe ngamalungu amaninzi aphambili, iintsika zentsimbi, imiqadi yentsimbi, iintsimbi zophahla lwentsimbi, uphahla lwentsimbi neendonga.Ikwabandakanya amanye amalungu kunye namacandelo entsimbi.Luhlobo luni lwempembelelo amacandelo aphambili asetyenziswa ngokuqhelekileyo kwiindibano zocweyo zesakhiwo sentsimbi kumgangatho wesakhiwo ngokubanzi?
Ukuchaneka kweisakhiwo sentsimbi umzi-mvelisoukucaciswa kwecandelo lokwenziwa kwezinto yimfuneko yokuqinisekisa umgangatho uwonke wesakhiwo somzi-mveliso wentsimbi.Ngoko ke, kuyimfuneko ukuqonda ngokuchanekileyo ukuchaneka kunye nokuphazamiseka kwekholamu yentsimbi yesikwele, umgama phakathi komngxuma wokudibanisa wekholomu kunye nomqadi kwi-plate ephantsi yekholomu, kunye nokucutshungulwa komngxuma wokudibanisa ngokwawo.Ukuchaneka, ukuchaneka kweeplanga zephahla kunye nokucubungula ukuchaneka kweeplati zokudibanisa i-column-beam, inkcazo yokuqhelaniswa kweentonga zokubopha kwiiplanga kunye neentsika okanye iiplati ezixhasayo zokudibanisa ngokubhekiselele kwimiqadi kunye neentsika ngokwazo, ukucaciswa kokuqhelaniswa kweeplati ezixhasayo ze-purlin, njl.
Okwangoku, ikholamu ephakathi ye-workshop yesakhiwo sensimbi yenziwe nge-H steel processing okanye i-plate assembly.Ukuba icutshungulwa yintsimbi ye-H eyenziwe nge-shelf, ukuchaneka kokuveliswa kwekholomu kulula ukuyilawula;ukuba idityaniswe kwizinto zepleyiti, nikela ingqalelo emva kokuhlanganisana kunye ne-welding.Ukubunjwa kweentsika zetsimbi ukuqinisekisa ukuthe tye kwekholamu kunye nokuthintela ukujija.
Uninzi lwamaplanga ophahla luyizakhiwo ze-herringbone, ezihlanganiswe ngokubanzi ukusuka kwi-2 okanye kwi-4 trusses.Imiqadi yophahla idityaniswe ngokubanzi ngumenzi ngamacwecwe, kwaye iiwebhu zemiqadi ziqhelekile ukuba zibe zii-quadrilaterals ezingaqhelekanga.Abavelisi abanobuchule obunamandla bobugcisa banokubamba ngokuchanekileyo ukunyuswa kunye nokuvalwa kwewebhu, ngelixa abavelisi abanezakhono zobugcisa ezibuthathaka abaqinisekanga malunga neewebhu.Nangona kunjalo, kukho iimpazamo kwiinkcukacha zokuphakama.Ngenxa yokuba ukucaciswa kwemilo yophahla lwephahla kuhambelana nokuqina koxhulumaniso phakathi kwentsimbi kunye nekholomu, ukucaciswa kwewebhu kuchaphazela ngokuthe ngqo ukucaciswa kwemilo ye-beam, ngoko kubaluleke kakhulu.
Kwisakhiwo sesakhiwo sefektri yesakhiwo sensimbi, amacandelo amaninzi aqhelekileyo aquka iikholomu zetsimbi kunye neentsimbi zetsimbi, eziyinxalenye enkulu yokuxhasa kunye nokuthwala umthwalo, kwaye ziyinxalenye ebalulekileyo yokubunjwa kwesakhiwo.Ifom ye-cross-section yekholomu yensimbi ihlulwe kwikholamu yewebhu eqinile kunye nekholamu ye-lattice.Ikholamu yewebhu eqinile inecandelo elipheleleyo, elisetyenziswa ngokuqhelekileyo licandelo le-I-shaped kunye necandelo le-H;icandelo lekholamu ye-lattice lihlulwe libe ngamacandelo amabini okanye amaninzi amaninzi, kwaye imilenze idibaniswe yimichilo okanye iipaneli.Xa umthwalo ukhulu kunye nekholomu Xa umzimba ubanzi, isixa sensimbi esetyenzisiweyo sincinci.
Imiqadi yentsimbi, imiqadi yentsimbi emile, kunye nemiqadi edibeneyo.Iiplanga zensimbi zingasetyenziselwa iiplanga ze-crane kunye neeplanga ezisebenzayo kwiindibano zocweyo, iiplanga zomgangatho kwizakhiwo ezinama-multi-storey, i-purlins kwizakhiwo zephahla, njl.Ukucutshungulwa kweentsimbi ezibunjiweyo zilula kwaye iindleko zincinci, kodwa ubukhulu becala lobunqamlezo bentsimbi obunjiweyo bukhawulelwe neenkcukacha ezithile.Xa umthwalo kunye nobubanzi bukhulu kwaye icandelo lensimbi alikwazi ukuhlangabezana nokuqina, ukuqina okanye iimfuno zokuzinza, i-beam edibeneyo isetyenziswa.
Imiqadi edibeneyo idityaniswe okanye ihlanjululwe ngamacwecwe ensimbi okanye iintsimbi zecandelo.Ngenxa yokuba i-riveting inzima kakhulu kwaye ifuna izinto ezininzi, ukuwelda kudla ngokuba yeyona ndlela iphambili.Iintsimbi ezidityanisiweyo ezisetyenziswa ngokuqhelekileyo ziyi-H-shaped cross-sections kunye nebhokisi-shaped cross-sections eyenziwe ngamacwecwe e-flange aphezulu nangaphantsi kunye neewebhu.Le yokugqibela ibiza kakhulu kwaye ineenkqubo zokwenziwa ezintsonkothileyo , kodwa inokuqina okugoba okukhulu kunye nokuqina kwe-torsional, kwaye ifanelekile kwiimeko apho imithwalo esecaleni kunye neemfuno ezithintekayo ziphezulu okanye ukuphakama kwe-beam kulinganiselwe.
Amacandelo aphambili eubunjineli besakhiwo sentsimbiinokubunjwa ngokukhetha izixhobo ezahlukeneyo.Izinto ezahlukeneyo nazo zineeyantlukwano ezithile ekusebenzeni kwendalo kunye nomgangatho.Iindidi ezahlukeneyo zeeworkshops nazo zingakhiwa, ezifana neeworkshops zesakhiwo sentsimbi enemigangatho emininzi, iindibano zocweyo zesakhiwo sentsimbi ekhanyayo, Kwizakhiwo zefektri yesitena kunye nezinye iintlobo zezakhiwo, kuphela ngokulawula umgangatho wamacandelo anxulumeneyo unokufaka umgangatho welonke. ulwakhiwo luphuculwe.
