Danga Lachitsulo Lazitsulo Zopangira Zitsulo Zopangira Malo Ogulitsira

Chitoliro cha chitoliro chimatanthawuza mawonekedwe a lattice opangidwa ndi kulumikiza ndodo zozungulira kumapeto.Ma truss amapangitsa kuti kapangidwe ka truss kukhala kopanda ndalama, ndipo kapangidwe kake kamakhala kopepuka, ndipo ndikosavuta kupanga mawonekedwe osiyanasiyana kuti agwirizane ndi zolinga zosiyanasiyana, monga ma trusses, ma arches, mafelemu, ndi nsanja.

Poyerekeza ndi dongosolo gululi, tubular truss dongosolo amapulumutsa m'munsi chord longitudinal mamembala ndi olowa ozungulira a gululi chimango, amene angathe kukwaniritsa zofunikira za mitundu yosiyanasiyana yomanga, makamaka yomanga arches ozungulira ndi mongotsatira akalumikidzidwa yokhotakhota n'kopindulitsa kuposa kapangidwe ka grid.Kukhazikika kwake kumbali zonse ndikofanana, kupulumutsa kugwiritsa ntchito zinthu.Chitsulo chachitsulo cha truss chimapangidwa pamaziko a gululi.Poyerekeza ndi mawonekedwe a gridi, ili ndi ubwino wake wapadera komanso zotheka, ndipo kuchuluka kwa zitsulo zopangidwe kumakhalanso ndalama zambiri.

Kachitidwe:

1. Mphamvu:

Mlozera wamphamvu wachitsulo umapangidwa ndi zotanuka malire σe, zokolola malire σy, ndi tensile malire σu.Mapangidwe amachokera ku mphamvu zokolola zachitsulo.Mphamvu zokolola zambiri zimatha kuchepetsa kulemera kwa kapangidwe kake, kupulumutsa chitsulo, komanso kuchepetsa mtengo.Mphamvu yamphamvu σu ndiye kupsinjika kwakukulu komwe chitsulo chimatha kupirira chisanalephereke.Panthawiyi, kamangidwe kameneka kamataya ntchito yake chifukwa cha kusinthika kwakukulu kwa pulasitiki, koma kapangidwe kake kamakhala kosasunthika ndipo sikugwa, zomwe zimakwaniritsa zofunikira za dongosololi kuti zithetse chivomezi chosowa.Mtengo wa 'Σu / σy ukhoza kuwonedwa ngati gawo la nkhokwe yachitsulo.

2. Pulasitiki:

Pulasitiki yachitsulo nthawi zambiri imatanthawuza kukhala ndi mapindikidwe ofunikira apulasitiki osathyoka pambuyo poti kupsinjika kumadutsa gawo lokolola.Zolozera zazikulu zoyezera kuthekera kwa pulasitiki kupindika kwachitsulo ndi kutalika δ ndi kuchepa kwa gawo ψ.

3. Kuchita kozizira kopinda:

Kuzizira kopindika kwachitsulo ndi muyeso wa kukana kwachitsulo kusweka pamene kupunduka kwa pulasitiki kumachitika kutentha.Kuzizira kopindika kwachitsulo ndiko kugwiritsa ntchito kuyesa kopendekera kozizira kuyesa momwe chitsulo chimapindikira pansi pa digirii yopindika.

4. Kulimba kwamphamvu:

Kulimba kwachitsulo kumatanthawuza kuthekera kwa chitsulo kutengera mphamvu zamakina zamakina panthawi yosweka pansi pa katundu.Ndi katundu wamakina omwe amayesa kukana kwachitsulo kuti akhudze katundu.Zitha kuyambitsa kuwonongeka kwa brittle chifukwa cha kutentha pang'ono komanso kupsinjika maganizo.The impact toughness index of chitsulo nthawi zambiri imapezeka kudzera mu mayeso a zotsatira za zidutswa zoyeserera.

5. Kuwotcherera:

Kuwotcherera kwachitsulo kumatanthawuza zolumikizira zowotcherera zomwe zimagwira ntchito bwino pansi pazikhalidwe zina zowotcherera.kuwotcherera ntchito akhoza kugawidwa mu kuwotcherera ntchito ndi kuwotcherera ntchito ndondomeko kuwotcherera.Kuwotcherera ntchito mu ndondomeko kuwotcherera amatanthauza chiwopsezo cha kuwotcherera msoko ndi zitsulo pafupi ndi kuwotcherera msoko kuti palibe ming'alu matenthedwe kapena kuzirala shrinkage ming'alu pa ndondomeko kuwotcherera.Kuchita bwino kwa kuwotcherera kumatanthawuza kuti pansi pazikhalidwe zina zowotcherera, chitsulo chowotcherera ndi chitsulo chapafupi sichidzasweka.Kugwira ntchito kwa kuwotcherera potengera kuthekera kwa ntchito kumatanthawuza kulimba kwamphamvu komanso ductility kwa malo omwe akhudzidwa ndi kutentha pa msoko wowotcherera.China itengera njira yoyesera yowotcherera pakuwotcherera, komanso imatengera njira yoyesera yowotcherera momwe imagwirira ntchito.

6. Kukhalitsa:

Pali zinthu zambiri zomwe zimakhudza kulimba kwachitsulo.Choyamba ndi kusagwira bwino kwa dzimbiri kwachitsulo, ndipo njira zotetezera ziyenera kuchitidwa kuti zitsulo zisawonongeke komanso dzimbiri.Njira zodzitetezera ndizo: kukonza utoto wachitsulo nthawi zonse, kugwiritsa ntchito zitsulo zamalata, komanso kugwiritsa ntchito njira zodzitetezera pakakhala zinthu zowononga kwambiri monga ma acid, alkalis, ndi mchere.Ingot ya zinc imakhazikika pa jekete, ndipo electrolyte yamadzi am'nyanja idzangowononga ingot ya zinc poyamba, kuti ikwaniritse ntchito yoteteza jekete lachitsulo.Kachiwiri, chifukwa cha kutentha kwakukulu ndi katundu wa nthawi yayitali, mphamvu ya chiwonongeko chachitsulo ndi yotsika kuposa mphamvu yanthawi yochepa.Choncho, zitsulo zotentha kwambiri za nthawi yayitali ziyenera kuyesedwa kuti zikhale ndi mphamvu za nthawi yaitali.Chitsulocho chidzakhala cholimba komanso chosasunthika pakapita nthawi, zomwe ndizochitika za "kukalamba".Kulimba kwachitsulo pansi pa kutentha kochepa kumayesedwa.

Poyerekeza ndi miyambo zitsulo trusses ndi lotseguka mtanda zigawo (H woboola pakati zitsulo ndi ine woboola pakati chitsulo), zinthu za chitoliro truss dongosolo ndi wogawana kwambiri kugawanika kuzungulira ndale olamulira, kotero kuti mtanda ndi wabwino compressive ndi flexural- torsional kunyamula mphamvu ndi kukhazikika kwakukulu.Popanda mbale ya gusset, mawonekedwe ake ndi osavuta.Chofunika kwambiri ndi chakuti mawonekedwe a tubular truss ndi okongola m'mawonekedwe, omwe ndi abwino kuwonetserako komanso amakhala ndi zokongoletsera zina.Ntchito yonse ya mawonekedwe a chitoliro cha chitoliro ndi yabwino, kulimba kwa torsional ndi kwakukulu, ndipo mawonekedwe ake ndi okongola.Ndiosavuta kupanga, kukhazikitsa, kutembenuza, ndi kukweza;Chitsulo cha denga lachitsulo chopangidwa ndi chitsulo chozizira chokhala ndi mipanda yopyapyala chimakhala ndi mawonekedwe opepuka, osasunthika bwino, kupulumutsa zitsulo, ndipo amatha kusewera kwathunthu Ubwino wa mphamvu zakuthupi, ndi zina zotero, ndizochepa kwambiri, makamaka muzitsulo ndi chithandizo. olamulidwa ndi slenderness chiŵerengero.Nyumba zokhala ndi izi ndi nyumba za anthu.Kapangidwe kameneka kamakhala ndi mawonekedwe owoneka bwino (amatha kupangidwa kukhala athyathyathya, mawonekedwe ozungulira, mawonekedwe opindika), kupanga ndi kukhazikitsa kosavuta, kukhazikika kwamapangidwe, kukhazikika kwadenga, komanso kukhazikika kwachuma.

Zopangira zitsulo za kampani yathu zimatha kukumana ndi miyeso yosiyanasiyana yapadziko lonse lapansi monga muyezo waku Australia, New Zealand standard, Britain standard ndi American standard.Landirani kufunsa kwanu.
