Ufakelo lweZakhiwo zeNsimbi
Isakhiwo sensimbi sisakhiwo esakhiwe ngezinto zetsimbi kwaye yenye yeentlobo eziphambili zezakhiwo zokwakha.Ulwakhiwo ubukhulu becala luqulunqwe ngamaplanga entsimbi, iintsika zetsimbi, iintsimbi zentsimbi kunye nezinye izinto ezenziwe ngentsimbi yecandelo kunye neepleyiti zentsimbi, kwaye yamkela ukususwa komhlwa kunye neenkqubo zokuthintela umhlwa ezifana ne-silanization, i-phosphating ecocekileyo ye-manganese, ukuhlamba kunye nokomisa, kunye ne-galvanizing.I-Welds, i-bolts okanye i-rivets idla ngokusetyenziselwa ukudibanisa amacandelo okanye iinxalenye.Ngenxa yobunzima bayo obulula kunye nokwakhiwa okulula, isetyenziswa ngokubanzi kwiindibano zocweyo ezinkulu, iindawo, iindawo eziphakamileyo eziphezulu kunye nezinye iindawo.Isakhiwo sentsimbi kulula ukugqwala.Ngokuqhelekileyo, isakhiwo sensimbi sidinga ukuchithwa, i-galvanized okanye ipeyinti, kwaye kufuneka igcinwe rhoqo.
Iimpawu zentsimbi zinamandla amakhulu, ubunzima obulula, ukuqina okuhle ngokubanzi, kunye nokuchasana okunamandla kwi-deformation, ngoko ke ilungele ukwakhiwa kwezakhiwo ezinkulu, eziphezulu, kunye nezakhiwo ezinzima kakhulu;izinto eziphathekayo zine-homogeneity elungileyo kunye ne-isotropy, kwaye i-elasticity efanelekileyo.Ihambelana neengqikelelo ezisisiseko zobuchwephesha bobunjineli ngokubanzi;izinto eziphathekayo zineplastiki elungileyo kunye nokuqina, zinokuba ne-deformation enkulu, kwaye inokumelana nemithwalo eguquguqukayo kakuhle;ixesha lokwakha lifutshane;iqondo layo lokurhweba liphezulu, kwaye ingasetyenziselwa imveliso ekhethekileyo kunye nenqanaba eliphezulu lomatshini.
Intsimbi ephezulu yokuqina kufuneka ifundwe kwizakhiwo zetsimbi ukuze iphucule kakhulu amandla ayo okuvunwa;ukongeza, iintlobo ezintsha zentsimbi kufuneka ziqengqiwe, ezifana H-beam (ekwabizwa ngokuba yintsimbi ebanzi-flange) kunye T-ezimilise intsimbi kunye neepleyiti zentsimbi profiled ukuziqhelanisa nezakhiwo-span ezinkulu kunye Imfuneko izakhiwo super eliphezulu-ukuphakama. .
Ukongeza, akukho thermal ibhulorho ukukhanya inkqubo yentsimbi isakhiwo.Isakhiwo ngokwaso asiwongi amandla.Le teknoloji isebenzisa izihlanganisi ezikhethekileyo ezinobuchule ukusombulula ingxaki yeebhulorho ezibandayo kunye nezishushu kwisakhiwo;isakhiwo esincinci se-truss sivumela iintambo kunye nemibhobho yamanzi ephezulu nangaphantsi ukuba idlule eludongeni.Ukuhlobisa kukulungele.
Iimpawu zesakhiwo sensimbi
1. Amandla aphezulu aphezulu kunye nobunzima obulula
Intsimbi inamandla aphezulu kunye nemodyuli ephezulu yokuqina.Xa kuthelekiswa nekhonkrithi kunye neenkuni, umlinganiselo wokuxinana kwawo ekuveliseni amandla aphantsi, ngoko ke phantsi kweemeko ezifanayo zoxinzelelo, isakhiwo sentsimbi sinecandelo elincinci elinqamlezayo kunye nobunzima obulula, obulungele ukuthuthwa kunye nofakelo, kwaye lufanelekile. imilenze emikhulu, imilenze emide, kunye nemithwalo enzima.Ulwakhiwo.
2. Ukuqina kwensimbi, iplastiki enhle, izinto ezifanayo kunye nokuthembeka okuphezulu kwesakhiwo
Ilungele ukuthwala ukothuka kunye nomthwalo oguqukayo, kwaye inokusebenza kakuhle kwe-seismic.Ubume bangaphakathi bentsimbi bufana, kufuphi ne-isotropic ye-homogeneous body.Ukusebenza kwangempela kwesakhiwo sensimbi kuhambelana ngakumbi nethiyori yokubala.Ngoko ke, ukuthembeka kwesakhiwo sensimbi kuphezulu.
3. Iqondo eliphezulu lomatshini wokwenziwa kwesakhiwo sentsimbi kunye nokufakwa
Amalungu olwakhiwo lwentsimbi kulula ukwenza kwiifektri kwaye ahlangane kwisiza.Umzi-mveliso owenziwe ngoomatshini wamacandelo entsimbi anobuchwephesha obuphezulu, ukusebenza kakuhle kwemveliso, isantya sokuhlanganisa ngokukhawuleza kwindawo, kunye nexesha elifutshane lokwakha.Isakhiwo sentsimbi sesona sakhiwo siphuculwe kakhulu.
4. Ukusebenza kakuhle kokutywinwa kwesakhiwo sensimbi
Ngenxa yokuba isakhiwo esidibeneyo sinokutywinwa ngokupheleleyo, sinokwenziwa kwizikhongozeli zoxinzelelo oluphezulu, amachibi amakhulu e-oyile, imibhobho yoxinzelelo, njl njl.
5. Ulwakhiwo lwentsimbi alukwazi ukumelana nobushushu kwaye alukwazi ukumelana nomlilo
Xa iqondo lobushushu lingaphantsi kwe-150 °C, iimpawu zentsimbi zitshintsha kancinci.Ngoko ke, isakhiwo sentsimbi sifanelekile kwiindibano zocweyo ezishushu, kodwa xa umphezulu wesakhiwo ubonakaliswe kwimitha yokushisa emalunga ne-150 ° C, kufuneka ikhuselwe yibhodi yokushisa ukushisa.Xa izinga lokushisa liphakathi kwe-300 ° C kunye ne-400 ° C, amandla kunye ne-elastic modulus yensimbi iyancipha kakhulu.Xa iqondo lobushushu limalunga ne-600°C, amandla entsimbi athanda ukuya ku-zero.Kwizakhiwo ezineemfuno ezikhethekileyo zokukhusela umlilo, isakhiwo sensimbi kufuneka sikhuseleke ngezinto eziphikisayo zokuphucula ukulinganiswa kokumelana nomlilo.
6. Ukunganyangeki kwe-corrosion yesakhiwo sensimbi
Ngokukodwa kwindawo yemithombo yeendaba emanzi kunye neyonakalisayo, kulula ukugqwala.Ngokuqhelekileyo, ulwakhiwo lwensimbi ludinga ukuchithwa, i-galvanized okanye ipeyinti, kwaye kufuneka igcinwe rhoqo.Ukwakhiwa kweqonga elingaselunxwemeni kumanzi olwandle, amanyathelo akhethekileyo afana ne "zinc block anode protection" kufuneka yamkelwe ukuthintela ukubola.
7. Ikhabhoni ephantsi, ukugcinwa kwamandla, ukukhuselwa okuluhlaza kunye nokusingqongileyo, ukuchithwa kokwakhiwa kwesakhiwo sensimbi kuya kuba nzima ukuvelisa inkunkuma yokwakha, kwaye insimbi ingaphinda isetyenziswe kwaye isetyenziswe kwakhona.
