Ulwakhiwo lwegridi yendawo lunokwahlulwa lube zeziphi iintlobo kunye neempawu zokusebenza

Ulwakhiwo lwegridi yendawo lunokwahlulwa lube ludidi oluphindwe kabini lweplate-uhlobo lwesakhiwo segridi yendawo, umaleko omnye kunye nolwaleko oluphindwe kabini lohlobo lwegridi yendawo. Iintonga zohlobo lwepleyiti lwegridi yendawo kunye noluhlu oluphindwe kabini lwegridi yendawo yodidi lweqokobhe zohlulwe zaba yintonga yechord ephezulu, intonga yechord esezantsi kunye nentonga yewebhu, ethwala ubukhulu becala amandla kunye noxinzelelo. Iindawo zokuhlala zomaleko omnye-uhlobo lwegridi yesithuba ngokubanzi zicingelwa ukuba ziqhagamshelwe ngokungqongqo, kwaye kufuneka zibalwe ngokwendlela yesiqalelo esinesiphelo senkqubo yentonga edityaniswe ngokungqongqo; Umaleko ophindwe kabini iqokobhe-uhlobo lwegridi yendawo ingabalwa ngokwendlela yesiqalelo esinesiphelo senkqubo yentonga echaziweyo. Iqokobhe elinye nohlobo oluphindwe kabini lwegridi yendawo nayo ingasetyenziselwa ukwenza lula ubalo lwendlela ecetywayo yeqokobhe.

Iinduku zegridi yendawo yeqokobhe elilodwa, ukongeza kuxinzelelo kunye noxinzelelo, zikwathwala umzuzu wokugoba kunye namandla okucheba. Okwangoku, uninzi lwesakhiwo segridi saseTshayina samkela ulwakhiwo lwegridi yohlobo lweplate. Isakhiwo segridi luhlobo lwesakhiwo segridi yendawo. Okubizwa ngokuba "isakhiwo sendawo" sinxulumene "nesakhiwo sendiza", sinophawu lwezenzo ezintathu-dimensional. Ukususela ekuqalisweni kwesakhiwo sendawo, yamkelwe ngabantu ngokusebenza kwayo ngamandla, inoveli kunye nefom enhle kunye nokwakhiwa okukhawulezayo nokufanelekileyo. Ubume bendawo bunokuthathwa njengokwandiswa kunye nobunzulu besakhiwo senqwelomoya. isakhiwo segridi yendawo yinkqubo yentonga yesithuba, iintonga ikakhulu zithwala amandla e-axial, kwaye ubungakanani becandelo elinqamlezayo lincinci.

Ukwakhiwa kwegridi ibe yenye yeentlobo ezintsha zezakhiwo ezisetyenziswa ngokuqhelekileyo kwihlabathi lanamhlanje. Ilizwe lethu ukusukela ngeminyaka yoo-1960s laqala ukufunda nokusebenzisa, kwiminyaka yakutshanje, ngenxa yophuhliso olukhawulezayo lwetekhnoloji yekhompyutha ye-elektroniki, ukusombulula ubume begridi yendawo yesakhiwo esiphakamileyo se-super-static yengxaki yokubala, eshukunyiswa sisakhiwo segridi yendawo nokuba uhlobo lwemiba kunye nezicelo zobunjineli ezizizo, uphuhliso olukhawulezayo.

igridi yendawo efuna indawo enkulu, amabala emidlalo amakhulu, amaziko emiboniso, amaziko enkcubeko, iindawo zezothutho kunye nokubaishishini Steel Structure Warehouse, bonke babona umkhondo wesakhiwo sendawo. Iinzuzo zesakhiwo segridi yendawo yincinci encinci yensimbi, ingqibelelo efanelekileyo, ukuveliswa ngokukhawuleza kunye nokufakwa, kwaye ingasetyenziselwa ifom yesicwangciso esinzima. Isebenza kwiintlobo ezahlukeneyo zesakhiwo se-span, ngakumbi kwimilo yendiza enzima. Oku kunqumla indawo yentonga kunye nokuxhasana, intonga yamandla kunye nenkqubo yokuxhasa indibaniselwano ye-organic, kwaye ngaloo ndlela uqoqosho lwezinto ezibonakalayo.

igridi yendawo isetyenziswa ikakhulu kwizakhiwo zikawonke-wonke ezinkulu neziphakathi, ezinje ngeSteel Structure Stadium,Ulwakhiwo lwentsimbi yesiKhululo seenqwelomoya, iiklabhu,IiHolo zeMiboniso yeZakhiwo zentsimbikwayeUlwakhiwo lweNsimbi yesiKhululo sikaloliwe, njl., kunye nezityalo ezincinci kunye neziphakathi kunye nokuqalisa ukuthandwa kwesicelo. Ubukhulu bexesha, ukuphakama kunye nefuthe lezoqoqosho kwesi sakhiwo kubaluleke kakhulu. Isakhiwo segridi yendawo yeplate-uhlobo lwegridi yendawo yolwahlulo lwaziindidi ezintathu ngokwendlela yokwakheka: udidi lokuqala luqulunqwe yinkqubo ye-plane truss, kukho iindlela ezine zegridi yeendlela ezimbini ze-orthogonal orthodromic spatial, iindlela ezimbini ze-orthodromic diagonal spatial. igridi, igridi eneendlela ezimbini ediagonal yediagonal spatial kunye negridi yesithuba esineendlela ezintathu; udidi lwesibini luqulathe iyunithi yekhowuni ye-quadrangular, kukho iindidi ezintlanu zegridi ebekwe ngokufanelekileyo ye-quadrangular cone yendawo, igridi yesithuba ye-quadrangular cone, igridi ye-quadrangular cone yendawo ye-quadrangular, ibhodi ye-tesselating yegridi ye-quadrangular cone yendawo kunye negridi ye-spatial yenkwenkwezi udidi luqulathe iyunithi yekhowuni engunxantathu, kukho igridi yekhowuni engunxantathu wekhowuni, ukumpompa igridi engunxantathu wekhowuni yendawo kunye negridi yobusi yekhowuni engunxantathu yegridi yesithuba. Isakhiwo segridi yesithuba sodidi lweqokobhe ngokobume bomphezulu weqokobhe lunomhlathi womphezulu weqokobhe-uhlobo lwegridi yesithuba, igridi engqukuva yeqokobhe lesithuba kunye nohlobo lwegridi yesithuba ebaxwayo. Ulwakhiwo lwegridi yendawo ngokwezinto ezisetyenziswa kwigridi yentsimbi, igridi eyomeleziweyo yendawo kunye nentsimbi kunye nekonkrithi eyomeleziweyo eyenziwe ngokudityaniswa kwegridi yendawo, apho igridi yendawo yentsimbi isetyenziswe ngakumbi.

Ngokwenkangeleko eyahlukileyo, ulwakhiwo lwegridi yendawo lunokwahlulwa lube ludidi oluphindwe kabini lweplate-uhlobo lwesakhiwo segridi yendawo, umaleko omnye kunye nolwaleko oluphindwe kabini lohlobo lwegridi yendawo. Iinduku zegridi yendawo yohlobo lwepleyiti kunye ne-double-layer-shell-type grid grid yohlulwe yaba yintonga yechord ephezulu, intonga yechord esezantsi kunye ne-web rod, ezixhomekeke ikakhulu kuxinzelelo kunye noxinzelelo; iintonga zomaleko omnye wohlobo lwegridi yendawo zixhomekeke kumzuzu wokugoba kunye namandla okucheba ukongeza kuxinzelelo kunye noxinzelelo. Okwangoku, uninzi lwesakhiwo segridi yesithuba saseTshayina samkela ulwakhiwo lwegridi yohlobo lweplate.

Ngokutsho kokusetyenziswa kwangempela: isakhiwo sensimbi sisakhiwo sendawo esenziwe ngeentonga ezininzi ezixhunywe ngama-nodes ngokuhambelana nefom yegridi ethile. Ineenzuzo zamandla asemajukujukwini, ubunzima obulula, ubungqongqo obuphezulu, ukusebenza kakuhle kwenyikima, njl. njl. Ingasetyenziswa njengophahla lwejimnasium, ithiyetha, iholo yomboniso, iholo yokulinda, ikhenopi yesitediyamu, i-hangar, umnatha wekholamu eneendlela ezimbini. isakhiwo sesakhelo esivela kwindawo yokusebenzela kunye nezinye izakhiwo.

Igridi yendawo ineempawu zobunzima bokukhanya, ukomelela okuphezulu, ubulukhuni obulungileyo bubonke, amandla oguquko olomeleleyo, njl. Ulwakhiwo lophahla luqulunqwe yinkqubo yecandelo lentsimbi epholileyo, kwaye i-skeleton yentsimbi yenziwe nge-anticorrosive high-high-strength-rolled galvanized sheet, ethintela ngokufanelekileyo impembelelo yomhlwa kunye nokubola kwepleyiti yentsimbi. inkqubo yokwakha kunye nokusetyenziswa, kunye nokwandisa ubomi benkonzo yamacandelo ensimbi elula. Ubomi besakhiwo bunokufikelela kwiminyaka eyi-100.

Isixhobo sokugquma se-thermal esisetyenziselwa igridi yendawo yentsimbi ubukhulu becala buboya be-fiberglass, obunesiphumo esihle sokufakelwa kwe-thermal, kwaye sinokusetyenziswa njengebhodi yokugquma i-thermal eludongeni lwangaphandle ukunqanda ngokufanelekileyo into "yebhulorho ebandayo" kunye nokufezekisa isiphumo esingcono sokufakelwa kwe-thermal. . Isetyenziswe kwibhodi yokufakelwa kwe-thermal yodonga lwangaphandle, olunokuthi luphephe ngokufanelekileyo isiganeko "sebhuloho ebandayo" eludongeni, kwaye sifezekise umphumo ongcono wokushisa. I-100mm ubukhulu be-R15 umqhaphu wokugquma we-thermal unokulingana nexabiso lokumelana ne-thermal lodonga olungqingqwa lwe-1m. Ukuhlanganiswa kwesakhiwo segridi ngokuqhelekileyo kuqhutyelwa kwisayithi. Ngaphambi kokuba ushiye umzi-mveliso wesakhelo se-bolt node ye-mesh yebhola kufuneka ibe yi-pre-assembly, ukwenzela ukujonga ubungakanani beengxenye kunye nokutenxa. indibano yegridi yendawo kufuneka ibe ngokweendlela zokwakha kunye nofakelo, ukusetyenziswa kwendibano yomcu, indibano ekhawulezayo okanye indibano iyonke. indibano yegridi yendawo kufuneka iqhutywe kwiqonga elithe tyaba eliqinileyo. Ukudibanisa iibhola ze-welding ze-mesh zesakhelo ekuhlanganiseni, umyalelo wokudibanisa kufuneka ukhethwe ngokuchanekileyo ukunciphisa i-welding deformation kunye noxinzelelo lwe-welding, ngokuhambelana namava eeprojekthi ezininzi zasekhaya, umyalelo wokudibanisa kunye ne-welding kufuneka uphuhliswe ukusuka phakathi ukuya kwi-welding. macala amabini okanye macala onke, kwaye kungcono ukuphuhliswa ukusuka embindini ukuya kumacala amabini, kuba isakhelo se-mesh sinokuqhagamshelwa ngokukhululekileyo kwiziphelo zombini kunye necala langaphambili xa kuhlanganiswa phambili. Emva kwe-welding enye i-internode, iimveliso zesakhiwo sentsimbi zinokujonga ubungakanani kunye nejometri kube kanye, ukuze zinikwe uhlengahlengiso ngumshiseli kwindawo elandelayo yokuwelda. Imijikelezo evaliweyo kufuneka igwenywe kwindibano yezakhelo ze-mesh. Ukuwelda kwizangqa ezivaliweyo kuya kubangela uxinzelelo oluphezulu lwe-welding.
