Umehluko phakathi kwe-I-beam ne-H-beam

Umehluko phakathi kwe-I-beam HW HM Hn H-beam

I-HW HM HN H yigama elijwayelekile le-H-beam, i-H-beam i-welded;I-HW HM HN iyashisa

I-HW isho ukuthi ukuphakama kwensimbi emise okwe-H kanye nobubanzi be-flange ngokuyisisekelo kuyalingana;isetshenziselwa ikakhulukazi ikholomu yensimbi ekholamu yesakhiwo sikakhonkolo esiqinisiwe, eyaziwa nangokuthi ikholomu yensimbi eqinile;isetshenziselwa ikakhulukazi ikholomu esakhiweni sensimbi

I-HM isilinganiso sobude bensimbi obumise okwe-H kuya kububanzi be-flange cishe bungu-1.33~~1.75, ikakhulukazi ezakhiweni zensimbi: esetshenziswa njengamakholomu ohlaka lwensimbi kanye nemishayo yohlaka ezakhiweni zohlaka ezithwele imithwalo enamandla;isibonelo: izinkundla zemishini

I-HN isilinganiso sobude bensimbi emise okwe-H kuya kububanzi be-flange bukhulu noma bulingana no-2;isetshenziselwa ikakhulukazi imishayo;

Ukusetshenziswa kwe-I-beam kulingana nalokho kwe-HN-beam;

1. Kungakhathaliseki ukuthi insimbi emise okwe-I ijwayelekile noma ilula, ngenxa yokuthi usayizi we-cross-sectional uphakeme futhi uncane, umzuzu we-inertia wemikhono emibili eyinhloko esigabeni esiphambanayo uhluke kakhulu.Ngakho-ke, ngokuvamile ingasetshenziswa kuphela ngokuqondile kuwebhu yayo Amalungu okugoba endizeni noma awahlanganise abe amalungu agcizelelwe ohlobo lwe-lattice.Ayifanele amalungu e-axial compression noma amalungu ancike endizeni yewebhu futhi anamalungu agobile, akhawulela ububanzi bokusebenza kwayo.

2. Imishayo ye-H ingeyephrofayili yokusika esebenza kahle kakhulu kanye neyongayo (eminye ihlanganisa insimbi enezindonga ezincane ezakhiwe ngendlela ebandayo, amapuleti ensimbi anephrofayili, njll.), ngenxa yokuma okunengqondo kwesigaba esiphambene, angenza insimbi isebenze kahle futhi ngcono umthamo wokusika.Ngokungafani ne-I-shaped evamile, i-flange yensimbi efana ne-H iyandiswa, futhi izindawo zangaphakathi nangaphandle zivame ukufana, okwenza kube lula ukuxhuma nezinye izingxenye ezineminenke yamandla aphezulu.Ubukhulu bayo bakha uchungechunge olunengqondo, futhi amamodeli aphelele, alungele ukuklama nokukhethwa.

3. Ama-flange ensimbi emise okwe-H wonke anobukhulu obulinganayo, kunezigaba ezigoqiwe, futhi kukhona nezigaba ezihlanganisiwe ezakhiwe ngamapuleti amathathu ashiselwe.Ama-I-imishayo ayizigaba ezigoqiwe.Ngenxa yobuchwepheshe obumpofu bokukhiqiza, unqenqema lwangaphakathi lwe-flange lunomthambeka ongu-1:10.Ukugingqika kwensimbi emise okwe-H kuhlukile kunensimbi evamile emise okwe-I enesethi eyodwa kuphela yamaroli avundlile.Ngenxa yokuthi i-flange yayo ibanzi futhi ayinayo i-slope (noma i-slope encane), kuyadingeka ukwengeza iqoqo lemiqulu eqondile ukuze igingqike ngesikhathi esifanayo.Ngakho-ke, , inqubo yayo yokugoqa kanye nemishini iyinkimbinkimbi kakhulu kunemishini evamile yokugoqa.Ukuphakama okuphezulu kwe-h-beam egoqiwe engakhiqizwa e-China ngu-800mm, engashiselwa kuphela ingxenye ehlanganisiwe.
