Chii chinonzi H-Beam neI-Beam?
Chii chinonzi H-Beam?
H-dandachinhu chekugadzira mapuranga einjiniya chine simba guru rekutakura mutoro uye dhizaini yakareruka. Chakakodzera zvakanyanya zvivakwa zvesimbi zvemazuva ano zvine masipidhi makuru uye zvinorema zvakanyanya. Maitiro ayo akajairwa uye zvakanakira zvemakanika zvinotungamira hunyanzvi hwetekinoroji yeinjiniya muminda yekuvaka, mabhiriji, simba, nezvimwewo.
Chii chinonzi I-Beam?
I-dandachinhu chinokotamira chimwe chete nenzira isingadhuri. Nekuda kwemutengo wayo wakaderera uye nyore kugadzirisa, inoshandiswa zvakanyanya mumamiriro ezvinhu akadai sematanda echipiri muzvivakwa uye zvinotsigira michina. Zvisinei, yakaderera pane H-beam mukudzivirira torsional uye mutoro wekutakura zvinhu nenzira dzakawanda, uye kusarudzwa kwayo kunofanirwa kunge kwakavakirwa pane zvinodiwa nemashini.
Musiyano weH-Beam neI-Beam
Musiyano wakakosha
H-Beam:Maflange (zvikamu zvepamusoro nepazasi zvakatwasuka) zveH-beam zvakafanana uye zvine ukobvu hwakafanana, zvichigadzira chikamu che "H" chakaita sesikweya. Ane simba rakanaka rekukotama uye rekudzivirira kutenderera, zvichiita kuti akwanise zvivakwa zvinotakura mutoro.
I-Beam:Maflange eI-beam akatetepa mukati uye akafara kunze, ane mukwidza (kazhinji 8% kusvika 14%). Ane chikamu chakaita se "I", chakatarisana nekusagona kukotama uye kukwirira, uye anowanzo shandiswa pamatanda echipiri akaremerwa zvishoma.
Kuenzanisa kwakadzama
H-Beam:Simbi yakaita seHIbhokisi rinodzivirira kutenderera rakagadzirwa nemaflanges akafara zvakaenzana uye akakora uye mawebhu akamira. Rine hunhu hwakakwana hwemakanika (kukombama kwakanaka, kutenderera, uye kuramba kumanikidzwa), asi mutengo waro wakakwira. Rinonyanya kushandiswa mumamiriro ezvinhu anotakura mutoro wepakati akadai semakoramu ekuvaka akareba, matanda edenga efekitari ane span hombe, uye matanda ecrane anorema.
I-Beam:I-matandakuchengetedza zvinhu uye kuderedza mari nekuda kwekugadzirwa kwazvo kweflange slope. Dzinoshanda zvakanaka kana dzichikotamira kune imwe nzira, asi hadzina simba rekutenderera. Dzakakodzera zvikamu zvechipiri, zvakaremerwa zvishoma, zvakaita sematanda echipiri emufekitori, zvinotsigira michina, uye zvivakwa zvenguva pfupi. Idzi mhinduro inodhura zvishoma.
Maitiro ekushandisa H-Beam neI-Beam
H-Beam:
1. Zvivako zvakareba kwazvo (zvakaita seShanghai Tower) - mbiru dzakafara dzinodzivirira kudengenyeka kwenyika uye simba remhepo;
2. Matanda edenga remaindasitiri ane mativi makuru - anodzivirira kukotama zvakanyanya anotsigira makireni anorema (matani makumi mashanu zvichikwira) nemidziyo yedenga;
3. Zvivakwa zvesimba - mafuremu esimbi echigadzirwa chemagetsi ekupisa anodzivirira kumanikidzwa uye tembiricha yakakwira, uye mashongwe emhepo anopa rutsigiro rwemukati kudzivirira kuzununguka kwemhepo;
4. Mabhiriji anorema - mabhuroko emugungwa anodzivirira kutakura zvinhu zvinofamba-famba uye ngura yemvura yegungwa;
5. Michina inorema - kuchera ma hydraulic supports uye ship keels zvinoda matrix ine torsion yakakwira uye inodzivirira kuneta.
I-Beam:
1. Mapuranga ekuvaka ezvivakwa zveindasitiri - Maflange ane makona anotsigira zvakanaka mapurati esimbi ane mavara (anotambanudzwa pasi pe15m), nemari yakaderera ne15%-20% pane maH-beams.
2. Zvishandiso zvemidziyo yakareruka - Matereki eConveyor nemafuremu madiki epuratifomu (kukwanisa kutakura zvinhu pasi pematani mashanu) zvinosangana nezvinodiwa zvekutakura zvinhu zvisingachinji.
3. Zvivakwa zvenguva pfupi - Matanda ekuvaka escaffolding uye makoramu ekutsigira mashedhi ekuratidzira zvinosanganisa kuunganidza nekukurumidza nekuputsa uye kushanda zvakanaka kwemari.
4. Mabhiriji asingaremeri zvakawanda - Mabhiriji ane matanda akatsigirwa mumigwagwa yekumaruwa (akareba <20m) anoshandisa simba rawo rekudzivirira kukotama zvisingadhuri.
5. Nheyo dzemichina - Zvigadziko zvemichina nemafuremu emichina yekurima zvinoshandisa chiyero chazvo chekuomarara nehuremu.
