I-beam inhengo yechimiro ine I-shaped cross-section (yakafanana neguta guru "I" rine serifs) kana H-yakaumbwa. Mamwe mazwi ehunyanzvi ane hukama anosanganisira H-beam, I-section, universal column (UC), W-beam (inomirira "wide flange"), universal beam (UB), rolled steel joist (RSJ), kana double-T. Izvo zvakagadzirwa nesimbi uye zvinogona kushandiswa mune zvakasiyana-siyana zvekuvaka zvikumbiro.
Pazasi, ngatienzanise mutsauko uripo pakati peH-beam neI-beam kubva kune-cross-sectional maonero. Zvishandiso zveH-beam
H-beam inowanzoshandiswa mumapurojekiti anoda marefu akareba uye yakakwirira-yekutakura kutakura, zvakadai semabhiriji uye zvivakwa zvepamusoro-soro.
H Beam Vs I Beam
Simbi ndiyo inonyanya kuchinjika, inogara ichishandiswa zvimiro zvinhu. Ose maviri H Beam uye ini Beam ndiwo anonyanya kuzivikanwa zvimiro zvinhu zvinoshandiswa mukutengesa kuvaka kuvaka.
Ose ari maviri akafanana muchimiro kuvanhu venguva dzose, asi pane misiyano yakakura pakati pezviviri izvi, izvo zvakakosha kuti uzive.
Chikamu chakachinjika chezvose H uye I matanda chinodaidzwa kuti maflange, nepo chikamu chakatwasuka chichizivikanwa se "dandemutande." Dandemutande rinobatsira kutakura mauto ekugera, ukuwo maflange akagadzirwa kuti asamirire nguva yekukotama.
Ini chii, Beam?
Icho chikamu chechimiro icho chimiro chakafanana neguta guru I. Inosanganisira maflange maviri akabatanidzwa newebhu. Iyo yemukati yemukati yemaflange ine slop, kazhinji, 1: 6, iyo inoita kuti ive gobvu mukati uye mutete kunze.
Somugumisiro, inoita zvakanaka pakutakura mutoro pasi pekumanikidzwa kwakananga. Iri danda rine tapeed edges uye yakakwirira-chikamu-chikamu kureba kana zvichienzaniswa nehupamhi hweflange.
Zvichienderana nekushandiswa, zvikamu zve-I-beam zvinowanikwa muhupamhi hwekudzika, kukora kwewebhu, upamhi hweflange, huremu, uye zvikamu.
Chii chinonzi H Beam?
Iyo zvakare inhengo yezvimiro iyo yakaumbwa seguta guru H rine simbi yakakungurutswa. H-chikamu matanda anoshandiswa zvakanyanya kune zvekutengesa uye zvekugara zvivakwa nekuda kwesimba-kusvika-huremu reshiyo uye yepamusoro mechanical zvivakwa.
Kusiyana neiyo I danda, iyo H beam flanges haina mukati mekuda, zvichiita kuti welding process ive nyore. Ose maflange ane ukobvu hwakaenzana uye anofanana kune imwe neimwe.
Hunhu hwayo hwemuchinjika-chikamu huri nani pane iyo I danda, uye ine zvirinani zvemichina pahuremu hweyuniti inochengetedza zvinhu uye mutengo.
Ndiyo inofarirwa zvinhu zvemapuratifomu, mezzanines, uye mabhiriji.
Pakutanga kutarisa, zvose H-chikamu uye I-chikamu matanda esimbi anotaridzika akafanana, asi mamwe misiyano yakakosha pakati peaya matanda maviri esimbi akakosha kuziva.
Shape
Iyo h danda inofanana nechimiro che Capital H, nepo I danda iri chimiro che Capital I.
Manufacturing
I-matanda anogadzirwa sechinhu chimwe chete mukati, nepo H-beam ichisanganisira matatu simbi mahwendefa akasungwa pamwechete.
H-matanda anogona kugadzirwa kune chero saizi yainoda, nepo muchina wekugaya unodzikamisa kugadzirwa kweI-matanda.
Flanges
H beam flanges ine ukobvu hwakaenzana uye inofanana kune imwe neimwe, nepo ini danda ndakateta maflange ane inclination ye 1: kusvika 1:10 kuti ive nani kutakura mutoro.
Webhu Kukora
Iyo h beam ine webhu yakakora zvakanyanya kana ichienzaniswa neiyo I beam.
Nhamba yezvidimbu
Iyo h-chikamu danda rakafanana nesimbi imwe chete, asi ine bevel apo mahwendefa matatu esimbi anobatanidzwa pamwechete.
Nepo I-chikamu danda risingagadzirwe nekuturika kana riveting simbi mashizha pamwechete, inongova chikamu chimwe chesimbi zvachose.
Kurema
H matanda anorema pakurema kana achienzaniswa nematanda eI.
Distance From Flange end To Web's center
Muchikamu cheI, chinhambwe kubva kumucheto weflange kusvika kuWebhu pakati padiki, nepo muH-chikamu, Iyo kureba kubva kumucheto weflange kuenda kuWebhu pakati yakakwira kune yakafanana chikamu cheI-beam.
Simba
Iyo h-chikamu danda inopa simba rakawanda pahuremu hweyuniti nekuda kweyakakwenenzverwa mhiri-chikamu nharaunda uye yakanakisa simba-ku-huremu reshiyo.
Kazhinji, matanda e-I-chikamu akadzika kupfuura yakafara, zvichiita kuti ave akanaka kwazvo pakutakura mutoro pasi pebhangi remunharaunda. Uyezve, iwo akareruka muhuremu kupfuura H-chikamu matanda, saka haazotore mutoro wakakosha seH-matanda.
Kuoma musoro
Kazhinji, H-chikamu matanda akanyanya kuomarara uye anogona kutora mutoro unorema kupfuura I-chikamu matanda.
Muchinjikwa-chikamu
Iyo I-chikamu danda rine nhete-chikamu chakakodzera kutakura mutoro wakananga uye tension stress asi haina kunaka pakumonyoroka.
Mukuenzanisa, iyo H danda ine yakafara muchinjiko-chikamu pane iyo I danda, iyo inogona kubata yakananga mutoro uye kusimba kushushikana uye kuramba kumonyoroka.
Kureruka kweWelding
H-chikamu matanda anowanikwa zvakanyanya kune weld nekuda kweawo akatwasuka ekunze flanges kupfuura I-chikamu matanda. H-chikamu danda muchinjiko-chikamu chakasimba kupfuura I-chikamu danda muchinjiko-chikamu; saka inogona kutora mutoro wakakosha.
Nguva yeInertia
Iyo Moment yeInertia yedanda inosarudza kugona kwayo kuramba kukotama. Iyo yakakwirira ichava, zvishoma danda richakotama.
H-chikamu matanda ane maflange akafara, kuomarara kwepamusoro, uye nguva huru yekusagadzikana kupfuura I-chikamu matanda, uye anoshingirira kukotama kupfuura ini matanda.
Spans
I-section beam inogona kushandiswa kwenguva inosvika 33 kusvika 100 tsoka nekuda kwezvisingakwanisi kugadzira, nepo H-chikamu danda rinogona kushandiswa kwenguva inosvika 330 tsoka sezvo richikwanisa kugadzirwa chero saizi kana kureba.
Economy
Iyo H-chikamu danda chikamu chehupfumi chine hupfumi hwemagetsi zvinhu pane I-chikamu danda.
Application
H-chikamu matanda akanakira mezzanines, mabhiriji, mapuratifomu, uye kuvakwa kwezvivakwa zvekugara uye zvekutengesa zvivakwa. Iwo zvakare anoshandiswa kune iyo inotakura-inotakura mbiru, turera, uye marori mubhedha kuumba.
I-chikamu matanda ndicho chikamu chakagamuchirwa chemabhiriji, zvivakwa zvesimbi, uye kugadzirwa kwemafuremu ekutsigira nemakoramu ezvikwiriso, hoist uye zvinosimudza, trolleyways, trailer, uye mibhedha yemarori.
