isakhiwo segridi yendawo singahlukaniswa ukuthi yiziphi izinhlobo nezici zokusebenza

Isakhiwo segridi yendawo singahlukaniswa ngesakhiwo segridi yendawo enezingqimba ezimbili, ungqimba olulodwa kanye nesakhiwo segridi yendawo yegobolondo enezingqimba ezimbili. Izinduku zegridi yendawo yohlobo lwepuleti kanye negridi yendawo yohlobo lwegobolondo enezingqimba ezimbili zihlukaniswa zaba induku yokucula engenhla, induku yokucula ephansi kanye ne-web, ethwala kakhulu amandla nokucindezela. Amanodi egridi yendawo yohlobo olulodwa lwegobolondo ngokuvamile acatshangwa ukuthi axhumeke ngokuqinile, futhi kufanele abalwe ngokuvumelana nendlela yesici esilinganiselwe sesistimu yezinduku ezixhunywe ngokuqinile; Igridi yendawo yegobolondo enezingqimba ezimbili ingabalwa ngokuya ngendlela yesici esilinganiselwe sesistimu yenduku eshiwo. Igridi yendawo yohlobo lwegobolondo elilodwa nekabili ingasetshenziswa ukwenza lula ukubalwa kwendlela yegobolondo ehlongozwayo.

Izinti zegridi yendawo yegobolondo longqimba olulodwa, ngaphezu kokuthwala ukungezwani nokucindezela, futhi zithwala umzuzu wokugoba namandla okugunda. Njengamanje, ingxenye enkulu yesakhiwo segridi yaseShayina isebenzisa ukwakheka kwegridi yohlobo lwepuleti. Isakhiwo segridi siwuhlobo lwesakhiwo segridi yesikhala. Okubizwa ngokuthi "isakhiwo sesikhala" sihlobene "nesakhiwo sendiza", sinesici sesenzo se-three-dimensional. Selokhu kwethulwa isakhiwo sesikhala, siye samukelwa ngabantu ngokusebenza kahle kwamandla, inoveli kanye nefomu elihle nokwakhiwa okusheshayo nokulula. Isakhiwo somkhathi singabuye sithathwe njengokunwetshwa nokujula kwesakhiwo sendiza. Ukwakheka kwegridi yendawo kuyisakhiwo sohlelo lwenduku yesikhala, izinduku zithwala amandla e-axial, futhi usayizi wesigaba esiphambanayo mncane uma kuqhathaniswa.

Ukwakheka kwegridi sekungenye yezinhlobo ezintsha zezakhiwo ezisetshenziswa kakhulu ezweni lanamuhla. Izwe lethu kusukela ngeminyaka yawo-1960 laqala ukufunda nokusebenzisa, eminyakeni yamuva nje, ngenxa yentuthuko esheshayo yobuchwepheshe bekhompiyutha kagesi, ukuxazulula uhlaka lwegridi yendawo yesakhiwo senkinga yokubala, esibangelwa uhlaka lwegridi yendawo noma ngabe uhlobo lwezici kanye nezicelo zangempela zobunjiniyela, ukuthuthukiswa kokushesha.

igridi yendawo edinga indawo enkulu, izinkundla ezinkulu zesikhala, izikhungo zemibukiso, izinsiza zamasiko, izindawo zokuhamba ngishoIndustrial Steel Structure Warehouse, bonke babona iminonjana yesakhiwo somkhathi. Izinzuzo zesakhiwo segridi yendawo yinani elincane lensimbi, ubuqotho obuhle, ukukhiqizwa okusheshayo nokufakwa, futhi ingasetshenziselwa ifomu lepulani eliyinkimbinkimbi. Isebenza ezinhlobonhlobo zesakhiwo se-span, ikakhulukazi ukuma kwendiza eyinkimbinkimbi. Lokhu kuphambana kwendawo kwenduku nokusekelana, i-force rod nesistimu yokusekela inhlanganisela yezinto eziphilayo, kanjalo nomnotho wezinto ezibonakalayo.

igridi yendawo isetshenziswa kakhulu ezakhiweni zomphakathi ezinkulu nezimaphakathi, njengezinkundla zeSteel Structure,Izakhiwo Zensimbi Yesikhumulo Sezindiza, amaklabhu,Amahholo Ombukiso Wezakhiwo ZensimbifuthiIzakhiwo Zensimbi Yesiteshi Sesitimela, njll., kanye nezitshalo zezimboni ezincane neziphakathi nendawo nazo seziqalile ukwenza isicelo saziwe. Ubukhulu be-span, ukuphakama kanye nomphumela wezomnotho walesi sakhiwo kubaluleke kakhulu. Isakhiwo segridi yendawo yeplate-uhlobo lwegridi yendawo ihlukaniswe ikakhulukazi izigaba ezintathu ngokuya ngefomu lokuqamba: isigaba sokuqala sakhiwe uhlelo lwe-plane truss, kunezinhlobo ezine zegridi ye-orthogonal orthodromic spatial enezindlela ezimbili, i-orthodromic diagonal space. igridi, igridi ye-diagonal space diagonal enezinhlangothi ezimbili kanye negridi yendawo enezinhlangothi ezintathu; isigaba sesibili siqukethe iyunithi yekhoni engu-quadrangular, kunezinhlobo ezinhlanu zegridi yendawo yekhoni engu-quadrangular ebekwe kahle, igridi yendawo yekhoni engu-quadrangular ekhishiwe, igridi yendawo yekhoni engu-quadrangular ebekwe ngokulinganayo, ibhodi le-tessellating ibhodi legridi yendawo yekhoni engu-quadrangular kanye negridi ye-spatial yenkanyezi yenkanyezi isigaba siqukethe iyunithi yekhoni engunxantathu, kukhona igridi yendawo yekhoni engunxantathu, igridi yendawo yekhoni engunxantathu empompayo kanye negridi yendawo yekhoni engunxantathu empompayo. Isakhiwo segridi yendawo yohlobo lwegobolondo ngokwendlela yengaphezulu legobolondo ikakhulukazi inegridi yendawo yohlobo lwegobolondo, igridi yendawo yohlobo lwegobolondo eyindilinga kanye negridi yendawo yegobolondo eyi-hyperbolic surface. isakhiwo segridi yendawo ngokuya ngezinto ezisetshenziswa kugridi yendawo yensimbi, igridi yendawo kakhonkolo eqinisiwe kanye nensimbi nokhonkolo oqinisiwe ohlanganiswe inhlanganisela yegridi yendawo, okusetshenziswe kakhulu igridi yendawo yensimbi.

Ngokubukeka okuhlukile, ukwakheka kwegridi yendawo kungahlukaniswa ngesakhiwo segridi yendawo enezingqimba ezimbili, ungqimba olulodwa kanye nesakhiwo segridi yohlobo lwegobolondo ephindwe kabili. Izinduku zegridi yendawo yohlobo lwepuleti kanye negridi yendawo yohlobo lwegobolondo enezingqimba ezimbili zihlukaniswe zaba induku yokucula engenhla, induku yokucula ephansi kanye nenduku yewebhu, engaphansi kakhulu kokushuba nokucindezela; izinti zegridi yendawo yohlaka olulodwa lwegobolondo zingaphansi kwesikhashana sokugoba namandla okugunda ngaphezu kokushuba nokucindezela. Njengamanje, ingxenye enkulu yesakhiwo segridi yendawo yaseShayina isebenzisa ukwakheka kwegridi yendawo yohlobo lwamapuleti.

Ngokusho kokusetshenziswa kwangempela: isakhiwo sensimbi yisakhiwo sesikhala esenziwe ngezinduku eziningi ezixhunywe ngama-node ngokuhambisana nefomu elithile legridi. Inezinzuzo zamandla omkhathi, isisindo esilula, ukuqina okuphezulu, ukusebenza kahle kokuzamazama komhlaba, njll. Ingasetshenziswa njengophahla lwenkundla yokuzivocavoca, yaseshashalazini, ihholo lombukiso, ihholo lokulinda, i-canopy yesitediyamu, i-hangar, ikholomu enezikhala ezimbili. isakhiwo sefreyimu esivela endaweni yokusebenzela kanye nezinye izakhiwo.

Igridi yendawo inezici zesisindo esilula, amandla aphezulu, ukuqina okuhle okuphelele, ikhono eliqinile lokuguquguquka, njll., futhi isidingo segridi yendawo siya ngokuba sikhulu ngokuba sikhulu njengamanje. Isakhiwo sophahla sakhiwe ngesistimu yezingxenye zensimbi ezacile ezakhiwe ngendlela ebandayo, futhi uhlaka lwamathambo ensimbi lwenziwe ngeshidi elinamandla eliqinile elinamandla elinamandla elinamandla abandayo, eligwema ngempumelelo ithonya lokugqwala nokugqwala kwepuleti lensimbi ngaphakathi. inqubo yokwakha nokusetshenziswa, futhi yandisa impilo yesevisi yezingxenye zensimbi ezingasindi. Impilo yesakhiwo ingaba yiminyaka eyi-100.

I-thermal insulation material esetshenziselwa isakhiwo sensimbi igridi yendawo ikakhulukazi i-fiberglass wool, enomphumela omuhle wokushisa oshisayo, futhi ingasetshenziswa njengebhodi lokufaka ukushisa okushisayo odongeni lwangaphandle ukuze kugwenywe ngempumelelo into "yebhuloho elibandayo" futhi kuzuzwe umphumela ongcono wokushisa ukushisa. . Isetshenziswa ebhodini lokufakelwa kwe-thermal odongeni lwangaphandle, olungagwema ngokuphumelelayo ukwenzeka "kwebhuloho elibandayo" lodonga, futhi kuzuzwe umphumela ongcono wokushisa oshisayo. Ugqinsi luka-100mm R15 we-thermal insulation value ungalingana nenani lokumelana nokushisa lodonga lwezitini oluwugqinsi oluyi-1m. Ukuhlanganiswa kwesakhiwo segridi ngokuvamile kwenziwa endaweni. Ngaphambi kokushiya imboni ye-bolt ball node mesh frame kufanele ibe pre-assembly, ukuze uhlole usayizi wezingxenye kanye nokuphambuka. umhlangano wegridi yendawo kufanele uhambisane nezindlela zokwakha nezindlela zokufaka, ukusetshenziswa kokuhlanganiswa kwe-strip, ukuhlanganiswa okusheshayo noma ukuhlanganiswa okuphelele. ukuhlanganiswa kwegridi yendawo kufanele kwenziwe endaweni yesikhulumi esiqinile. Ukuze uhlanganise ama-node angenalutho we-mesh frame ekuhlanganiseni, ukuhleleka kokuhlangana kufanele kukhethwe kahle ukuze kuncishiswe i-welding deformation kanye nokucindezeleka kwe-welding, ngokusho kokuhlangenwe nakho kwamaphrojekthi amaningi asekhaya, ukuhleleka kokuhlangana nokushisela kufanele kuthuthukiswe kusuka maphakathi kuya izinhlangothi ezimbili noma nxazonke, futhi kungcono ukuthuthukiswa kusukela phakathi kuya ezinhlangothini ezimbili, ngoba ifreyimu ye-mesh ingafinyelelwa ngokukhululekile emaphethelweni amabili nangaphambili lapho ihlangana phambili. Ngemva kokushisela i-internode eyodwa, imikhiqizo yesakhiwo sensimbi ingabheka usayizi kanye nejometri kanye, ukuze inikezwe ukulungiswa yi-welder endaweni elandelayo yokushisela. Imibuthano evaliwe kufanele igwenywe ekuhlanganiseni kwezinhlaka ze-mesh. Ukushisela emibuthanweni evaliwe kuzoholela ekucindezelekeni okuphezulu kwe-welding.
