Uphahla lweNtsimbi yoRhwebo eGalvanized yoRhwebo lweTruss yeNdawo yokuThengisa

I-pipe truss ibhekiselele kwisakhiwo selathisi esenziwe ngokudibanisa iintonga ezingqukuva eziphelweni.I-truss yenza ulwakhiwo lwe-truss lube noqoqosho, kwaye ulwakhiwo lulula kubunzima, kwaye kulula ukwenza iimilo ezahlukeneyo ukuziqhelanisa neenjongo ezahlukeneyo, ezinje ngeetrusi ezixhasiweyo, ii-arches, iifreyimu kunye neenqaba.

Xa kuthelekiswa nesakhiwo segridi, i-tubular truss structure igcina amalungu e-chord longitudinal esezantsi kunye namalungu angama-spherical wesakhelo segridi, enokuthi ihlangabezane neemfuno zeendlela ezahlukeneyo zokwakha, ngakumbi ukwakhiwa kwee-arches ezijikelezayo kunye neemilo ezigobileyo ezigobileyo kunenzuzo ngaphezu isakhiwo segridi.Ukuzinza kwayo kuzo zonke iinkalo kuyafana, ukugcina ukusetyenziswa kwezinto eziphathekayo.Isakhiwo sombhobho wentsimbi siphuhliswa ngesiseko sesakhiwo segridi.Xa kuthelekiswa nesakhiwo segridi, ineenzuzo zayo ezizodwa kunye nokusebenza, kwaye ubungakanani bensimbi yesakhiwo nayo inoqoqosho ngakumbi.

Ukusebenza:

1. Amandla:

Isalathiso samandla sentsimbi yenziwe ngomda weelastiki σe, umda wesivuno σy, kunye nomda we-tensile σu.Uyilo lusekelwe kumandla emveliso yentsimbi.Amandla aphezulu esivuno anokunciphisa ubunzima besakhiwo, gcina intsimbi, kunye nokunciphisa iindleko.Amandla okuqina σu lolona xinzelelo luphezulu intsimbi enokumelana nayo phambi kokusilela.Ngeli xesha, isakhiwo silahlekelwa ukusebenza kwayo ngenxa yokuguqulwa kweplastiki enkulu, kodwa isakhiwo asikho isikhubekiso kwaye asiyi kuwa, esihlangabezana neemfuno zesakhiwo ukuxhathisa inyikima enqabileyo.'Σu / σy ixabiso linokuthathwa njenge parameter yogcino lwamandla entsimbi.

2. Iplastiki:

Iplastiki yentsimbi ngokuqhelekileyo ibhekisela kwipropati yokuba ne-deformation ebalulekileyo yeplastiki ngaphandle kokuphuka emva kokuba uxinzelelo ludlula isivuno.Izalathisi eziphambili zokulinganisa isakhono seplastiki sokuguqulwa kwentsimbi lubude δ kunye nokuncipha kwecandelo ψ.

3. Ukusebenza okugoba okubandayo:

Ukusebenza okubandayo okugoba kwentsimbi ngumlinganiselo wokumelana nentsimbi ekuqhekekeni xa ukuguqulwa kweplastiki kwenzeka kwiqondo lokushisa.Ukugoba okubandayo kwentsimbi kukusebenzisa umfuniselo wokugoba obandayo ukuvavanya ukusebenza ngokugoba kwentsimbi phantsi kwesidanga esichaziweyo sokugoba.

4. Ukuqina kwempembelelo:

Ukuqina kwempembelelo yentsimbi kubhekiselele kwisakhono sentsimbi ukufunxa amandla e-kinetic oomatshini ngexesha lokwaphuka phantsi komthwalo wempembelelo.Yipropathi yomatshini elinganisa ukuchasana kwentsimbi ukuchaphazela umthwalo.Inokubangela i-brittle fracture ngenxa yobushushu obuphantsi kunye noxinzelelo loxinzelelo.Isalathiso sokuqina kwempembelelo yentsimbi ngokuqhelekileyo ifunyenwe ngovavanyo lwempembelelo yemilinganiselo yovavanyo oluqhelekileyo.

5. Ukusebenza kwe-welding:

Ukusebenza kwe-welding yentsimbi kubhekiselele kumalungu e-welding kunye nokusebenza kakuhle phantsi kweemeko ezithile zenkqubo ye-welding.Ukusebenza kwe-welding kunokwahlulwa ngokusebenza kwe-welding kunye nokusebenza kwe-welding kwinkqubo ye-welding.Ukusebenza kwe-Welding kwinkqubo ye-welding ibhekisela ekuthandeni kwe-welding seam kunye nesinyithi esikufutshane ne-welding seam ukuba kungabikho iintanda ze-thermal okanye ukupholisa ukuqhekeka kwe-shrinkage ngexesha lenkqubo ye-welding.Ukusebenza kakuhle kwe-welding kuthetha ukuba phantsi kweemeko ezithile zenkqubo ye-welding, isinyithi se-weld kunye nesiseko sentsimbi esisondeleyo asiyi kuqhekeka.Ukusebenza kwe-welding ngokwemigaqo yenkonzo ibhekiselele kukuqina kwempembelelo kunye ne-ductility yendawo echaphazelekayo yobushushu kwi-weld seam.I-China yamkela indlela yokuvavanya ukusebenza kwe-welding kwinkqubo ye-welding, kwaye yamkele indlela yokuvavanya ukusebenza kwe-welding kubume bokusetyenziswa.

6. Ukuqina:

Kukho izinto ezininzi ezichaphazela ukuqina kwentsimbi.Eyokuqala kukunganyangeki kwe-corrosion yentsimbi, kwaye amanyathelo okukhusela kufuneka athathwe ukukhusela i-corrosion yensimbi kunye ne-rust.Amanyathelo okukhusela abandakanya: ukugcinwa rhoqo kweepeyinti zetsimbi, ukusetyenziswa kwentsimbi ye-galvanized, kunye nokusetyenziswa kweendlela ezikhethekileyo zokukhusela phambi kwemithombo yeendaba ezomeleleyo ezifana ne-acids, alkalis, kunye neetyuwa.I-zinc ingot igxininiswe kwijacket, kwaye i-electrolyte yamanzi olwandle iya kutshabalalisa ngokuzenzekelayo i-zinc ingot kuqala, ukuze kufezekiswe umsebenzi wokukhusela ibhatyi yensimbi.Okwesibini, ngenxa yokushisa okuphezulu kunye nomthwalo wexesha elide, amandla okutshatyalaliswa kwentsimbi aphantsi kunoko kwamandla exesha elifutshane.Ngoko ke, intsimbi yexesha elide lobushushu obuphezulu kufuneka ivavanywe ngamandla exesha elide.Intsimbi iya kuba nzima ngokuzenzekelayo kwaye ibhubhe ngokuhamba kwexesha, into eyenzekayo "yokuguga".Ukuqina kwempembelelo yentsimbi phantsi komthwalo wobushushu obuphantsi kuya kuvavanywa.

Xa kuthelekiswa trusses zentsimbi zemveli kunye ezivulekileyo cross-amacandelo (intsimbi H-ezimilise kunye nentsimbi I-ezimilise), impahla yesakhiwo umbhobho truss isasazwa ngokulungeleleneyo ngeenxa axis cala, ukuze icandelo umnqamlezo ube elungileyo compressive kunye flexural- umthamo wokuthwala kunye nobunzima obukhulu.Ngaphandle kwe-gusset plate, isakhiwo silula.Eyona nto ibaluleke kakhulu kukuba isakhiwo se-tubular truss sihle ngokubonakala, esilungele ukubunjwa kunye nomphumo othile wokuhlobisa.Ukusebenza ngokubanzi kwesakhiwo se-truss yombhobho kulungile, ukuqina kwe-torsional kukhulu, kwaye ukubonakala kuhle.Kulula ukwenza, ukufaka, ukujika, kunye nokuphakamisa;umbhobho wentsimbi uphahla truss eyenziwe ngentsimbi ebandayo-eyenziwe ngentsimbi ebhityileyo inesakhiwo esilula, ukuqina okuhle, ukonga intsimbi, kwaye inokunika umdlalo opheleleyo Uncedo lwamandla ezinto eziphathekayo, njl., lunoqoqosho ngakumbi, ngakumbi kwi-strut kunye nenkxaso yenkqubo. kulawulwa ngumlinganiselo wokubhitya.Izakhiwo ezinesi sakhiwo zizakhiwo zikawonke-wonke.Ulwakhiwo luneempawu zenkangeleko entle (inokwakhelwa kwisimo esisicaba, imilo ye-arch engqukuva, imilo yegophe engaqhelekanga), imveliso efanelekileyo kunye nofakelo, uzinzo oluhle lwesakhiwo, ubulukhuni bophahla oluphezulu, kunye nesiphumo esihle sezoqoqosho.

Iimveliso zentsimbi yenkampani yethu zinokuhlangabezana nemigangatho eyahlukeneyo yamazwe aphesheya njengomgangatho wase-Australia, umgangatho waseNew Zealand, umgangatho waseBritane kunye nomgangatho waseMelika.Wamkele umbuzo wakho.
