Iyo yeEuropean standard H-beam marudzi HEA neHEB ane misiyano yakakura muchinjika-chikamu chimiro, saizi uye mashandisiro.
HEA series
HEA inopisa-yakakungurutswa yakafara-flangeH-dandamuEuropean standard, ine "H"-yakaumbwa muchinjika-chikamu chimiro, maviri akafanana anoshanda zviso (web) uye mahwendefa maviri eflange. HEA mhando H-beam inoratidzirwa neyakamanikana flanges uye yakakura kureba, iyo inoita kuti ive yakakodzera kune zviitiko nehombe yekukotama nguva, senge mabhiriji, yakakwirira-kukwira zvivakwa, etc.1. Kunyanya, HEA yakatevedzana masimbi anowanzo kushandiswa kune zvimiro zvinoda kusimba kwakanyanya uye kuomarara, senge mafuremu ekuvaka anoita zvakanaka pasi pemitoro yakatwasuka uye yakachinjika.
HEB series
Mukupesana, HEB mhando H-beam zvakare inopisa-yakakungurutswa ribbed wide-flange H-danda pasi peEuropean standard, asi maitiro ayo akasiyana neHEA. Iyo mhiri-chikamu nzvimbo yeHEB mhando H-beam inogona kunge idiki zvishoma pane iyo yeHEA, asi iyo flange yakafaranuka uye dandemutande rakakora, izvo zvinopa HEB mhando H-beam zvirinani compressive kuita uye inokodzera mamiriro ekushandisa anoda yakakura kuomarara2. Izvi zvinoreva kuti mune dzimwe nguva, kunyange zvazvocross-sectionalnzvimbo yeHEB idiki, inogona kupa rutsigiro rwakasimba nekuda kwekufara kwayo flange uye gobvu webhu.
1. Muchinjikwa-sectional dimensions uye geometric maitiro
•HEA nhevedzano (yakareruka H-beam)
▪Mafurange akatetepa uye akatetepa (maflange) nematande matete (mahwendefa akatwasuka epakati).
▪ Huremu huremu pahurefu hweyuniti uye nzvimbo diki yemuchinjikwa-chikamu.
▪ Yakaderera nguva yeinertia (kukotama kuramba) uye chikamu modulus, yakakodzera kune yepakati mitoro mamiriro.
•HEB series (standard H-beam)
▪Kupamhamha uye kukobvu maflange uye hutanda hwakakora.
▪Huremu hwechikwata chepamusoro uye zvakanyanya kuwedzera nzvimbo yepakati.
▪Nguva yekumusoro yeinertia uye chikamu modulus, kukotama kwakasimba uye kumanikidza kuramba, yakakodzera kune zvinorema-mutoro zvivakwa.
3. Mechanical properties uye maitiro ekushandisa
HEA
▪Inokodzera kureruka kusvika pakati pemitoro, yakadai semafuremu echirimwa akareruka, mapuratifomu madiki kana zvimiro zvisingatakuri.
▪ Upfumi hwakanaka, kuchengetedza mari yezvinhu.
HEB
▪Inoshandiswa muzviitiko zvinorema, zvakadai semapango makuru ebhiriji, mbiru dzekuvaka dzakakwirira kana zvitsigiro zvemichina inorema.
▪Kuoma kwepamusoro uye kusimba, asi kudhura kwezvinhu.
4. Mamwe eEuropean H-beam akatevedzana
▪HEM dzakatevedzana: makobvu flanges uye webs, akagadzirirwa mitoro yakanyanyisa (yakadai seheavy industry equipment bases).
▪IPN/IPE series: Yakafanana neHEA/HEB, asi ine parallel flange design (hapana mutsetse padivi remukati reflange).
Nzvimbo dzekushandisa
Nekuda kwekusiyana kwehunhu huri pamusoro, kushandiswa kweHEA neHEB mhando H-matanda muinjiniya chaiyo inotarisisawo pane zvakasiyana. HEA H-beam inonyanya kukodzera kune nzvimbo dzinoda kusimba kwepamusoro uye kusimba kwepamusoro, senge nheyo yekutsigira system yezvivakwa zvakakura kana core chubhu yezvivakwa zvepamusoro-soro. HEB H-beam, nekuda kwehupamhi hwayo hweflange uye dandemutande rakakora, rinonyatsoita zvakanaka kana raiswa mumitoro mikuru. Naizvozvo, inowanzo shandiswa muchimiro chenheyo yeanorema muchina kana maindasitiri zvidyarwa zvine zvakakwirira zvinodikanwa zvekutakura simba.
