YIZIPHI IZINHLOBO ZEZIGCAWU ZESAKHIWO EZIYI-HOLLOW?

YiniIzigaba Zesakhiwo Ezingenalutho?

I-Hollow Structural Sections (HSS) imele isigaba samaphrofayela ensimbi ngokuvamile aklanywe ngensimbi egoqelwe ebandayo, abunjwe abe ukumiswa kweshubhu. Leli fomu elihlukile liphumela onqenqemeni oluvulekile, olungagcwalisiwe olugijima kubo bonke ubude bebha yensimbi, okubenza babe nezinye “isigaba sebhokisi” kanye “nesigaba esingenalutho.” Ukwamukelwa kwe-HSS kukhule ngokuphawulekayo ngenxa yesimo sayo esithambile, ukuguquguquka, nobuqotho obuqinile besakhiwo, okuyenza ibe lula kakhulu emicabangweni yokusungula nokucabanga phambili.

Izinhlobo zezigaba zesakhiwo esingenalutho:

Izigaba Zesakhiwo Ezingenalutho zivame ukutholakala ngokucushwa okuthathu okuyinhloko: izingxenye ezingenalutho eziwunxande (RHS), izingxenye eziyisikwele ezingenalutho (SHS), kanye nezingxenye ezingenalutho eziyindilinga (CHS). Okuhlukile ngakunye kwesigaba esingenalutho kunikeza izinzuzo ezihlukile, izakhiwo, kanye nezinhlelo zokusebenza.

1.Square Hollow Sections (SHS):

I-SHS ine-cross-section yesikwele futhi ivame ukusetshenziswa ekwakhiweni kwezakhiwo lapho izimo eziyisikwele zikhethwa khona noma zidingeka. Ngokuvamile zisetshenziswa ekwakheni amafreyimu, amakholomu okusekela, nezinye izinhlelo zokusebenza zezakhiwo.

2.Izigodi Eziwunxande (RHS):

I-RHS inesiphambano esingunxande futhi isetshenziswa ezimeni lapho umumo ongunxande ufaneleka kakhulu. Ngokufana ne-SHS, i-RHS ivame ukusetshenziswa ekwakheni nasekwakheni izingxenye zesakhiwo.

3.Izingqimba Eziyindilinga Eziyindilinga (CHS):

I-CHS ine-cross-section eyisiyingi futhi isetshenziswa kaningi ezinhlelweni lapho umumo oyindilinga unenzuzo, njengokwakhiwa kwamakholomu, izigxobo, nezinye izakhiwo eziyisilinda. I-CHS yaziwa ngokusetshenziswa kwayo ngempumelelo kwezinto ezisetshenziswayo ekumelaneni nemithwalo ye-torsional.

I-Hollow Structural Sections (HSS) embonini yensimbi iziqhayisa ngezici ezimbalwa eziphawulekayo:

1.Izicelo Ezihlukahlukene Kuwo Wonke Izimboni:

I-HSS ithandwa kakhulu ngenxa yamandla ayo akhethekile okubekezelela imithwalo emikhulu phakathi nenkathi enwetshiwe. Lokhu kuguquguquka kwenza kube into ekhethwayo yamaphrojekthi adinga ukuzinza okuqinile. Ukuzivumelanisa nezimo kwe-HSS kuvumela ukusetshenziswa kwayo ezindaweni ezihlukahlukene, okuyenza ibe inketho enhle kakhulu yamaphrojekthi adinga ukuqina ngokumelene nezinto ezibolayo noma ezilimazayo.

2.Ikhono Lokuthwala Okuphezulu:

Esinye sezici ezibalulekile ze-HSS yikhono layo elimangalisayo lokumelana nemithwalo ephezulu, okuyenza ibe ukukhetha okuthembekile kwezinhlelo zokusebenza zesakhiwo lapho amandla ebaluleke kakhulu.

3.Broad Environmental Ukufaneleka:

I-HSS ibonisa ukuqina ezindaweni ezihlukahlukene, ivumela ukusetshenziswa kwayo kuzilungiselelo ezihlukahlukene. Lesi sici siyenza ifaneleke ikakhulukazi amaphrojekthi achayeka ezimeni ezilimazayo noma eziyinselele.
