ZEZIPHI IINTLOBO ZAMACANDELO OKWENZIWA OKUNGCWELE?

Yintoni iAmacandelo oLwakhiwo oluHoli?

I-Hollow Structural Sections (HSS) imele udidi lweeprofayili zentsimbi ezidla ngokuyilwa kwintsimbi eqengqelekayo ebandayo, emile kwimizobo yetubula.Le fomu yahlukileyo iphumela kumphetho ovulekileyo, ongagcwaliswanga ohamba kubo bonke ubude bentsimbi yentsimbi, ebafumana enye yeemonikhi "icandelo lebhokisi" kunye "necandelo elingenanto."Ukwamkelwa kwe-HSS kuye kwanda kakhulu ngenxa yemo yayo ethambileyo, ukuguquguquka, kunye nemfezeko yolwakhiwo eyomeleleyo, nto leyo eyenza ukuba isebenziseke ngakumbi kwiikhonsepthi zoyilo kunye nokucinga kwangaphambili.

Iindidi zamaCandelo oLwakhiwo oluHoli:

I-Hollow Structural Sections idla ngokufumaneka kwiinkqubo ezintathu eziphambili: i-rectangular hollow section (RHS), i-square hollow sections (SHS), kunye ne-circular hollow sections (CHS).Uluhlu ngalunye lwecandelo elingenanto lubonelela ngeendlela ezahlukeneyo, iipropathi, kunye nezicelo.

1.Square Hollow Sections (SHS):

I-SHS ine-square cross-section kwaye isetyenziswa rhoqo kulwakhiwo lwezakhiwo apho iimilo zesikwere zikhethwa okanye zifuneka.Ngokuqhelekileyo baqeshwe kwizakhelo zokwakha, iikholamu zenkxaso, kunye nezinye izicelo zokwakha.

2.AmaCandelo aHollow axande (RHS):

I-RHS ine-cross-section ye-rectangular kwaye isetyenziswa kwiimeko apho i-rectangular shape ifanelekile ngakumbi.Ngokufana ne-SHS, i-RHS isetyenziswa ngokuqhelekileyo ekwakheni nasekwakheni amacandelo olwakhiwo.

3.ISetyhula Hollow Sections (CHS):

I-CHS inomnqamlezo wesetyhula kwaye isetyenziswa rhoqo kwizicelo apho imilo yesetyhula inenzuzo, njengokwakhiwa kweekholomu, iipali kunye nezinye izakhiwo ze-cylindrical.I-CHS yaziwa ngokusetyenziswa kwayo ngokufanelekileyo kwezinto ekuxhathiseni imithwalo ye-torsional.

Amacandelo oLwakhiwo oluHoli (HSS) kwishishini lesinyithi liqhayisa ngezinto ezininzi eziphawulekayo:

1.Usetyenziso oluNxulunyanisiweyo kuwo wonke amaShishini:

I-HSS ithandwa ngokubanzi ngenxa yesakhono sayo esikhethekileyo sokunyamezela imithwalo enzima ngexesha elongeziweyo.Oku kuguquguquka kwenza ukuba ibe yimathiriyeli ekhethwayo kwiiprojekthi ezifuna uzinzo olomeleleyo.Ukuguquguquka kwe-HSS kuvumela ukusetyenziswa kwayo kwiindawo ezahlukeneyo, kuyenza ibe lolona khetho lubalaseleyo kwiiprojekthi ezifuna ukomelela ngokuchasene nezinto eziyonakalisayo okanye ezonakalisayo.

2.Isakhono soKuthwala uMthwalo:

Enye yeempawu eziphambili ze-HSS kukukwazi kwayo ukumelana nemithwalo ephezulu, iyenza ibe lukhetho oluthembekileyo kwizicelo zesakhiwo apho amandla abaluleke kakhulu.

3.Ukufaneleka kokuSingqongileyo okuBanzi:

I-HSS ibonisa ukomelela kwiindawo ezahlukeneyo, ivumela ukusetyenziswa kwayo kwiindawo ezahlukeneyo.Olu phawu lwenza ukuba lufaneleke ngokukodwa iiprojekthi ezivezwe kwiimeko ezinobungozi okanye ezicela umngeni.
