Iindlela zoFakelo lweZakhiwo zeNsimbi

Ngeengenelo ezibalaseleyo ezinje ngokuqina okuphezulu, ubunzima bokuzenzela, inqanaba eliphezulu lokushishina kunye nexesha elifutshane lokwakha,izakhiwo zentsimbiibe yeyona ndlela ingundoqo yolwakhiwo lwezityalo zale mihla, izakhiwo zikawonke-wonke ezinkulu kunye nezakhiwo eziphakamileyo. Ukufakwa kunye nokwakhiwa kwezakhiwo zetsimbi kusebenza njengekhonkco eliphambili lokudibanisa imizobo yoyilo kunye nezakhiwo ezibonakalayo, kunye nobuchwepheshe babo bokwakha kunye nokulawula umgangatho kuchaphazela ngokuthe ngqo ukhuseleko kunye nokuqina kwezakhiwo. Ukuqala ekulungiseleleni ukwakhiwa, eli phepha lihlela ngokucwangcisiweyo amanqaku angundoqo obugcisa bokufakelwa kwezakhiwo ezahlukeneyo zentsimbi ezibandakanya imigangatho enye, imigangatho emininzi kunye nezakhiwo zentsimbi eziphakamileyo kunye nezakhiwo zegridi yentsimbi, ukwenzela ukuba kubonelelwe ngokubhekisele kwintlangano yokwakha kwindawo kunye nokulawula umgangatho.

ULungiselelo loKwakha

Okokuqala, isikimu sobugcisa bofakelo siya kwenziwa. Ukufakela i-piece-piece-piece kwamkelwa kwizakhiwo zetsimbi ze-single-storey, ngelixa ukufakwa ngokubanzi kufakwe kwiinkqubo zephahla kunye nezakhiwo zetsimbi ezininzi. Ukongeza, izixhobo zokuxhoma, oomatshini bokwakha, izixhobo zentsimbi, izinto zokuwelda kunye neziqhoboshi ziya kuxhotyiswa ngokupheleleyo. Ukuphakama komgangatho weziseko zekholamu, iiasi kunye neebholiti ze-ankile ziya kutshekishwa kwakhona, iikhomponenti zentsimbi ziya kucocwa, kwaye imigca yokumisela yokubekwa iya kumakishwa.

Ukufakela iSingle-storey Structures

Iikholomu zentsimbi ziphakanyiswe nge-single-point lashing ngqo. Emva kokulungelelanisa kunye neebholiti ze-anchor zokulungiswa kwexeshana, indawo yazo kunye nokuma kwazo kuya kulinganiswa. Ukuqiniswa kokugqibela kweebholiti kunye ne-welding ye-base plates iya kuqhutywa ngaphambi kokuba i-grouting kwiziseko zekholomu. Imiqadi ye-Crane iphakanyiswe nge-lashing-point-lashing kwaye ixhotyiswe ngemigca yethegi ukuthintela ukungqubana; ukuphakama, i-axis kunye nokuma kwazo kuya kulungelelaniswa emva kokumiswa. Iintsika zophahla ziya kunyuswa kuphela emva kokuba iintsika zentsimbi zizinzisiwe. Amalungu ophahla anokudityaniswa kwangaphambili abe ziiyunithi ezidityanisiweyo eziqinileyo ukuze ziphakanyiswe, kwaye ii-purlins ziya kufakwa emva kokumiswa kweetrasi zophahla.

Ukufakela i-Multi-storey kunye ne-High-rise Steel Structures

Isibonelelo somatshini we-welding shrinkage deformation iya kugcinwa kumacandelo emigangatho emininzi kunye nezakhiwo zetsimbi eziphakamileyo. I-axes idluliselwe kwimigca yokulawula umhlaba ukunyuswa kunye nokulinganisa iikholomu zetsimbi. Ngaphambi kokuba uphakamise iintsimbi zetsimbi, iiparameters zekholamu zekholomu ziya kuhlolwa kwaye izixhobo zokukhusela zikhuselekile. Emva kokumiswa, ukuphakama kunye nemigca yeziko kuya kulinganiswa ngokuphindaphindiweyo, kulandelwa ukwakhiwa koqhagamshelwano lwazo zonke iintlobo zamacandelo.

Ukufakelwa kweSteel Space Truss

I-truss yendawo isetyenziswa ngokubanzi kwisakhiwo sophahla olude kunye namalungu axineneyo, izisa ubunzima bokwakha obuphezulu kunezakhiwo ezicwangcisiweyo. Yamkela ubukhulu becala iintlobo ezintathu zamalungu, kwaye iimilo ezahlukeneyo zeplani zinokudityaniswa ngokudibanisa iiyunithi ezininzi ezisisiseko. Kukho iindlela ezintathu ezisisiseko zokwakha iitrasi zesithuba: indibano yobude obuphezulu ayifuni zixhobo zinkulu zokunyusela kodwa idla isixa esikhulu senkxaso kwaye ibandakanya imisebenzi ebanzi yobude obuphezulu; Ufakelo oludityanisiweyo aludingi nkxaso, lubonisa umsebenzi ongaphantsi komgangatho ophezulu kunye nomgangatho ozinzileyo we-welding, kodwa ubeka iimfuno eziphezulu kwizixhobo zokuxhoma kunye neteknoloji yokwakha; i-high-altitude sliding igwema izixhaso zendibano ezipheleleyo ezinomgangatho ophakathi womsebenzi ophezulu kunye nokusabalalisa imithwalo yokunyusa, ngelixa iingoma ezikhethekileyo zokutyibilika ziya kubekwa kwangaphambili kwaye ukuchaneka kongqamaniso lokutyibilika kufuneka kulawulwe ngokungqongqo.

Isakhiwo sentsimbiUfakelo yiprojekthi ecwangcisiweyo efuna ulungelelwaniso lweenkqubo ezininzi zokusebenza kunye norhwebo. Umgangatho wayo kunye nokusebenza kakuhle kuxhomekeke kulungelelwaniso oludibeneyo lwamalungiselelo okuqala, izikimu zokuphakamisa, ukulungiswa kwenkqubo kunye nolawulo lokhuseleko. Kwizakhiwo ezinomgangatho omnye, okuphambili kuya kunikwa kulandelelwano lokuphakanyiswa kwecandelo kunye nokuzinza ngexesha lokumiswa. Kwizakhiwo ezinemigangatho emininzi kunye nezakhiwo eziphakamileyo, ulawulo olungqongqo luya kuphunyezwa phezu kwe-welding shrinkage deformation kunye nokuchaneka kokuhanjiswa okuthe nkqo. Ngokubhekiselele kwizakhiwo ze-truss zesithuba eside, iindlela zokwakha ezibandakanya ukuhlanganiswa kobude obuphezulu, ukunyuswa okudibeneyo kunye nokutyibilika kuya kukhethwa ngokweemeko zendawo yendawo, kunye norhwebo phakathi kokusetyenziswa kwenkxaso, umthwalo womsebenzi ophezulu kunye nomthamo wezixhobo ziya kulungiswa ngokufanelekileyo.

Kulwakhiwo oluyinyani, kuphela ngokuqonda ngokupheleleyo injongo yoyilo, ukuthobela ngokungqongqo iikhowudi kunye nemigangatho, ukomeleza ukubekwa kweliso kwisaveyi, kunye nokwamkela ngokuguquguqukayo iindlela ezifanelekileyo zokwakha ezilungelelaniswe neempawu zesakhiwo seeprojekthi ezahlukeneyo zinokuqinisekiswa ngokukhuselekileyo, ngokufanelekileyo nangokuchanekileyo kofakelo lwesakhiwo sentsimbi, ukubeka isiseko esiluqilima sonikezelo olukumgangatho ophezulu weprojekthi yonke yokwakha.

Ngeminyaka engama-21 yamava anzulu kushishino lwesakhiwo sentsimbi,EHSSyenza uluhlu olubanzi lweeprojekthi zesakhiwo sentsimbi ezigubungela ukuveliswa kunye nokufakwa kwezinto zentsimbi. Ukusukela ekusungulweni kweNyanga yeBhanti kunye neNdlela, siye sathumela ngaphandle intaphane yamacandelo amakhulu olwakhiwo lwentsimbi kwaye sahambisa iiprojekthi zofakelo lwaphesheya kweelwandle. Ukuqhayisa ngobuchule obubanzi bofakelo, sinakho ngokupheleleyo ukujongana nemingeni yofakelo lwezakhiwo ezahlukeneyo ezintsonkothileyo, ukusukela kwiindibano zocweyo zemizi-mveliso ezinomgangatho omnye kunye nezakhiwo ezinomgangatho ophezulu ukuya kwiitrasi eziqhelekileyo kunye neegridi zesithuba esikhulu. Ubuchule bethu obuqinileyo bobuchwephesha bukhusela ukusebenza okuzinzileyo kwexesha elide kuyo yonke iprojekthi yesakhiwo sentsimbi.
