COV HOM CHAW UA HAUJ LWM HOLLOW YOG DAB TSI?

Yog dab tsiCov Khoom Siv Hollow?

Cov Khoom Siv Hollow Structural Sections (HSS) yog ib pawg ntawm cov hlau profiles uas feem ntau ua los ntawm cov hlau txias-kuav, puab ua cov tubular configurations. Cov duab tshwj xeeb no ua rau muaj qhov qhib, tsis muaj ntug khiav raws tag nrho qhov ntev ntawm cov hlau, ua rau lawv tau txais lwm lub npe hu ua "box section" thiab "hollow section." Kev siv HSS tau nce siab heev vim nws cov duab yooj ywm, kev hloov pauv tau yooj yim, thiab kev ruaj khov ntawm cov qauv, ua rau nws tshwj xeeb tshaj yog rau cov tswv yim tsim tshiab thiab xav txog yav tom ntej.

Hom Hollow Structural Seem:

Cov Khoom Siv Hollow Structural Sections feem ntau muaj peb hom: rectangular hollow sections (RHS), square hollow sections (SHS), thiab circular hollow sections (CHS). Txhua hom hollow section muaj cov txiaj ntsig, cov yam ntxwv, thiab cov kev siv sib txawv.

1. Cov Tshooj Hollow Square (SHS):

SHS muaj ib daim duab plaub fab thiab feem ntau siv rau hauv kev tsim cov qauv uas nyiam lossis xav tau cov duab plaub fab. Lawv feem ntau siv rau hauv kev tsim cov thav duab, cov kem txhawb nqa, thiab lwm yam kev siv hauv kev tsim vaj tsev.

2. Cov seem Hollow (RHS):

RHS muaj ib daim duab plaub fab thiab siv rau hauv cov xwm txheej uas daim duab plaub fab zoo dua. Ib yam li SHS, RHS feem ntau siv rau hauv kev tsim kho thiab kev tsim kho rau cov khoom siv hauv tsev.

3. Cov Voj Voog Hollow Sections (CHS):

CHS muaj ib lub voj voog thiab feem ntau siv rau hauv cov ntawv thov uas lub voj voog zoo dua, xws li hauv kev tsim cov kem, ncej, thiab lwm yam qauv cylindrical. CHS paub txog nws txoj kev siv cov khoom siv zoo hauv kev tiv taus cov loads torsional.

Cov Khoom Siv Hollow Structural Sections (HSS) hauv kev lag luam hlau muaj ntau yam ntxwv tseem ceeb:

1. Cov Ntawv Thov Ntau Yam Thoob Plaws Kev Lag Luam:

HSS tau txais kev nyiam los ntawm ntau tus neeg vim nws muaj peev xwm tiv taus cov khoom hnyav thaum lub sijhawm ntev. Qhov kev hloov pauv no ua rau nws yog cov khoom siv zoo rau cov haujlwm uas xav tau kev ruaj khov. Kev hloov pauv ntawm HSS ua rau nws siv tau rau ntau qhov chaw sib txawv, ua rau nws yog qhov kev xaiv zoo rau cov haujlwm uas xav tau kev tiv thaiv kev kub ntxhov lossis cov khoom puas tsuaj.

2. Muaj peev xwm thauj khoom tau zoo:

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm HSS yog nws lub peev xwm zoo kawg nkaus los tiv taus cov khoom hnyav, ua rau nws yog qhov kev xaiv txhim khu kev qha rau cov ntawv thov kev tsim kho qhov twg lub zog yog qhov tseem ceeb.

3. Kev Haum Rau Ib Puag Ncig Dav Dav:

HSS muaj zog nyob rau hauv ntau qhov chaw sib txawv, ua rau nws siv tau rau ntau qhov chaw sib txawv. Qhov cwj pwm no ua rau nws tsim nyog rau cov haujlwm uas raug rau cov xwm txheej corrosive lossis nyuaj.
