Mhando dzemhando dzeH-beam dzemuEurope HEA neHEB dzine musiyano mukuru muchimiro, saizi uye mashandisirwo adzo.
HEA nhevedzano
HEA imhando yeflange yakafara inopetwa nemotoH-dandamuEuropean standard, ine chimiro che "H" chakaita se "cross-sectional shaped", nzvimbo mbiri dzekushanda dzakafanana (webs) uye maflange plate maviri. HEA type H-beam inoratidzwa nemaflange akatetepa uye kureba kukuru, izvo zvinoita kuti ive yakakodzera zviitiko zvine nguva dzakakura dzekukotama, senge mabhiriji, zvivakwa zvepamusoro, nezvimwewo.1. Kunyanya, simbi dzeHEA series dzinowanzo shandiswa kune zvivakwa zvinoda simba rakawanda uye kuomarara, senge mafuremu ekuvaka anoshanda zvakanaka pasi pemitoro yakatwasuka uye yakatwasuka.
HEB nhevedzano
Kusiyana neizvi, HEB mhando yeH-beam iH-beam ine ribbed wide-flange yakamonerwa neribbed pasi peEuropean standard, asi hunhu hwayo hwakasiyana neHEA. Nzvimbo yeHEB mhando yeH-beam inogona kunge iri diki zvishoma pane yeHEA, asi flange yayo yakafara uye dandemutande rakakora, izvo zvinoita kuti HEB mhando yeH-beam ishande zviri nani uye yakakodzera kushandiswa kwemamiriro ezvinhu anoda kuomarara kweflange2. Izvi zvinoreva kuti mune dzimwe nguva, kunyangwechikamu chakayambukaNzvimbo yeHEB idiki, inogona kupa rutsigiro rwakasimba nekuda kwehupamhi hwayo hwakakura uye dandemutande rakakora.
1. Zviyero zvemuchinjikwa uye hunhu hwejometri
•HEA series (yakareruka H-beam)
▪Maflange akatetepa uye matete (flanges) uye mawebhu akatetepa (maplate epakati akamira).
▪Huremu hwakareruka pahurefu hweyuniti uye nzvimbo diki yekubatanidza.
▪Nguva shoma yekusagadzikana (kupikisa kukotama) uye section modulus, yakakodzera mamiriro epakati nepakati.
•HEB series (yakajairika H-beam)
▪Matanho akafara uye akakora uye mawebhu akakora.
▪Huremu hweyuniti hwakakwira uye nzvimbo yakawedzera zvakanyanya.
▪Nguva yepamusoro yekusagadzikana uye kugadzikana kwechikamu, kusimba kwekukombama uye kuramba kudzvanywa, yakakodzera zvivakwa zvinorema
3. Hunhu hwemakanika uye mamiriro ekushandisa
HEA
▪Yakakodzera zvinhu zviri nyore kusvika pakati nepakati, zvakaita semafuremu emiti akareruka, mapuratifomu madiki kana zvivako zvisingatakuri mutoro.
▪Kuchengetedza mari zvakanaka, zvichideredza mari yekushandisa zvinhu.
CHIHEB
▪Inoshandiswa mumamiriro ezvinhu ane zvinhu zvinorema, zvakaita sematanda makuru emabhiriji, mbiru dzekuvaka dzakareba kana zvinotsigira michina inorema.
▪Kusimba kwakanyanya uye kuomarara, asi mitengo yezvinhu yakakwira.
4. Mamwe maEurope H-beam nhevedzano
▪HEM series: flanges dzakakora uye mawebhu akakora, akagadzirirwa zvinhu zvakanyanya (zvakadai semabhesi emidziyo yeindasitiri inorema).
▪IPN/IPE series: Yakafanana neHEA/HEB, asi ine dhizaini yeflange yakafanana (isina kutsvedza kurutivi rwemukati rweflange).
Nzvimbo dzekushandisa
Nekuda kwekusiyana kwehunhu hwataurwa pamusoro apa, kushandiswa kweHEA neHEB mhando H-beams muinjiniya chaiyo kunotarisawo pane zvakasiyana. HEA H-beam inonyanya kukodzera nzvimbo dzinoda kuomarara kwakanyanya uye simba rakawanda, senge sisitimu yekutsigira nheyo yezvivakwa zvikuru kana chubhu yepakati yezvivakwa zvirefu. HEB H-beam, nekuda kwehupamhi hwayo hweflange hwakakura uye dandemutande rakakora, inoshanda zvakanaka zvikuru kana ikabatwa nemitoro yakakura yekumanikidzwa. Nokudaro, inowanzoshandiswa muchimiro chenheyo yemichina inorema kana maindasitiri ane zvinodiwa zvepamusoro zvekukwanisa kutakura.
