Unolwazi olungakanani malunga nezi fomu zeSteel-structure?

Njengoko sigubungele iinkqubo ezine eziphambili kwiisakhiwo sentsimbiishishini ixesha lokugqibela, EHSS uya kuqhubeka ukuthatha ukuba uphonononge izakhiwo zentsimbi kulo mbandela. Kwizakhiwo zanamhlanje, ezinobunzima obukhulayo besakhiwo kunye neemfuno zokuthwala umthwalo, iifom zesakhiwo ezifana neegobolondo ze-lattice, iintambo zokuxhoma, izakhiwo zeentambo zentsimbi kunye neetyhubhu zentsimbi ezizaliswe ngekhonkrithi ziye zasetyenziswa ngokubanzi. Iindidi zesakhiwo sentsimbi eziveliswe kulo mbandela zonke zisetyenziswa ngokuqhelekileyo kubunjineli kunye neenkqubo zobugcisa ezivuthiweyo kunye nemigangatho ehambelanayo yokuxhasa, elawula imimandla yabo ehlukeneyo.

Ulwakhiwo lweqokobhe oluneqokobhe, njengoko igama libonisa, sisakhiwo segridi egobileyo esifana neqokobhe leqanda. Olona phawu lwayo lusekukwazini ukwenza iimilo ezigobileyo ezinje ngeedomes kunye neearches. Ukuqhayisa ngenkangeleko entle kunye nokulawula amandla asebenzayo, isetyenziswa ngokubanzi kwiindawo zomthambo ezinkulu, amaziko emiboniso, iiplanethiriyamu kunye nezindlu zokugcina izityalo.

Izakhiwo zokuxhoma zithatha iintambo zetsimbi ezomeleleyo njengezona nxalenye zingundoqo kwaye ziqonde izithuba ezinkulu ngokusebenzisa ipropathi eqinile yeentambo. Zibonisa umthamo omkhulu wokulinganisa, ubunzima bokuzimela kunye nokusetyenziswa kwentsimbi ephantsi, kwaye zamkelwe ikakhulu kwiibhulorho ezimisiweyo, amabala emidlalo amakhulu, iitheminali zeenqwelomoya kunye nezinye iiprojekthi.

Isakhiwo se-cable-membrane yeyona nto ixhaphakileyo kwaye isetyenziswa ngokubanzi phakathi kwazo zonke izakhiwo ze-membrane, eziqulunqwe ngezinto ze-membrane kunye nezixhobo zetsimbi okanye iziseko zensimbi. Amalaphu e-membrane ahlala eqatywe nge-PTFE okanye i-PVC. Inobunzima bokukhanya, amandla aphezulu kunye nokuguquguquka okukhulu ukwenza imiphezulu egobileyo yefomu ekhululekileyo, iqhele ukusetyenziselwa ii-canopies, ukufakwa kwe-landscape, izikhululo zokurhafisa kunye neendawo ezinokuphephetheka.

Ulwakhiwo oluxhaswa ngomtya luqulunqwe ngamacangci angaphezulu aqinileyo kunye neentambo zentsimbi eziguquguqukayo ezisezantsi ezidityaniswe ngama-struts, apho iintambo eziphezulu eziqinileyo zininzi ziyimiqadi yentsimbi okanye i-trusses, ngoko inokutolikwa njengesakhiwo esenziwe ngokudibanisa imiqadi yentsimbi okanye iitrasi ezineentambo zentsimbi ngokusebenzisa i-struts. Isakhiwo somtya we-beam yeyona ndlela iqhelekileyo kunye neqhelekileyo yale nkqubo yolwakhiwo kunye nemiqadi yentsimbi yewebhu eqinile njengamacandelo ayo aphezulu. Ebonisa ukulingana okuzimeleyo kunye nomthamo obalaseleyo wokuqhawula, izakhiwo ezixhaswe ngeentambo zisetyenziswa ikakhulu kuphahla olude kunye nezikhululo zeenqwelomoya.

Isakhiwo se-tube yensimbi egcwele ikhonkrithi sibhekisela kwisakhiwo esinekhonkrithi ezaliswe ngaphakathi kweetyhubhu zetsimbi ukuphucula kakhulu umthamo wokuthwala kunye ne-ductility. Ibonisa umthamo ophezulu wokuthwala kunye ne-ductility efanelekileyo, kwaye isetyenziswa ikakhulu njengamalungu oxinzelelo kwiikholamu zesakhiwo eziphezulu eziphakamileyo, iibhulorho ze-arch kunye nezakhiwo ezinde.

Izakhelo ze-portal, iifreyimu zetsimbi, iitrasi zetsimbi kunye nezakhiwo zegridi ezikhankanywe kwinqaku elidlulileyo ziqhayisa umthamo omkhulu wemarike kunye neyona mizekelo yesicelo esiphezulu, esebenza njengezona zikhetho eziphezulu kwiifektri ezincinci kunye neziphakathi, izakhiwo eziphakamileyo kunye nophahla oluqhelekileyo lwe-span enkulu. Ngokwahlukileyo, oonokrwece latticed, ukunqunyanyiswa izakhiwo, intambo-imembrane izakhiwo, umqadi izakhiwo umtya kunye nekhonkrithi-ezaliswe ityhubhu izakhiwo zentsimbi ezigqunywe kulo mba ziinkqubo eziphantsi ezikhethekileyo ezilungiselelwe iimeko ezibandakanya ispans ezikhethekileyo, izakhiwo super high-ukuphakama, ezivaliweyo lightweight kunye neemeko zoxinzelelo composite, kwaye zikwamela inkqubo yentsimbi ethandwayo nowa day.

Konkeiinkqubo zentsimbi yesakhiwoezigutyungelwe kwizavenge ezimbini zineenzuzo ezahlukileyo kwaye ziyancedisana, ngokudibeneyo zenza i-spectrum epheleleyo yobuchwephesha yobunjineli besakhiwo sentsimbi yangoku. Ngokukodwa, ulwakhiwo lwesakhelo sensimbi lwenza isiseko sesakhiwo sentsimbi edibeneyo; oonokrwece abalatyisiweyo kunye neegridi zesithuba zombini ziwela kudidi lwezakhiwo zegridi yendawo njengeendlela ezinxuseneyo; ukumiswa, i-cable-membrane kunye nezakhiwo ezixhaswe ngomtya zinokudibaniswa kunye neetrasi kunye neegridi ukwenza iinkqubo zexesha elide; izakhiwo zetsimbi ezithambileyo ezibandayo zisetyenziswa ikakhulu kwiinkqubo zokwakha intsimbi ekhaphukhaphu; kunye nezakhiwo ze-tube zetsimbi ezifakwe kwikhonkrithi ziyi-steel-concrete composite system-bearing loading systems.

Xa ukhetha iintlobo zezakhiwo zeeprojekthi eziphathekayo, uvavanyo olubanzi luya kuqhutywa ngokusekelwe kwimisebenzi yokwakha, iimeko zexeshana, izibonakaliso zezoqoqosho kunye neemfuno zeshedyuli yokwakha ukugqiba isisombululo esona sisombululo. Hlala ubukeleEHSSimijelo esemthethweni yesakhiwo sentsimbi yobuchwephesha uhlaziyo lobugcisa. Ngeminyaka engama-21 yokuzinikela kulwakhiwo lwentsimbi kunye nofakelo, sinikezela ngenkqubo epheleleyo yenkxaso yobuchwephesha kwiiprojekthi zakho ezinobuchwephesha obuqinileyo.
