I-beam inhengo yechimiro ine chikamu chakachinjika chakaita seI (chakafanana ne "I" mukuru ane maserif) kana H-shaped. Mamwe mazwi ehunyanzvi ane chekuita nawo anosanganisira H-beam, I-section, universal column (UC), W-beam (inomiririra "wide flange"), universal beam (UB), rolled steel joist (RSJ), kana double-T. Akagadzirwa nesimbi uye anogona kushandiswa mumabasa akasiyana-siyana ekuvaka.
Pazasi, ngatienzanisei musiyano uripo pakati peH-beam neI-beam kubva pamaonero akasiyana-siyana.
H-beam inowanzo shandiswa mumapurojekiti anoda nzvimbo refu uye kugona kutakura zvinhu zvakawanda, zvakaita semabhiriji nezvivakwa zvirefu.
H Beam Vs I Beam
Simbi ndiyo inonyanya kushandiswa uye inoshandiswa nguva dzose mukuvaka. H Beam neI Beam ndizvo zvinonyanya kushandiswa mukuvaka zvivakwa zvemabhizinesi.
Zvese zvakafanana muchimiro chevanhu vakajairwa, asi pane musiyano mukuru pakati pezviviri izvi, izvo zvakakosha kuziva.
Chikamu chakatambanuka chematanda ese eH neI chinonzi maflange, nepo chikamu chakamira chichizivikanwa se "dandemutande." Dandemutande rinobatsira kutakura masimba ekuchekerera, nepo maflange akagadzirwa kuti agare kwenguva refu kana achikotama.
Ndiri chii, Beam?
Icho chinhu chechimiro chine chimiro chakaita sehukuru I. Chine maflange maviri akabatanidzwa nedandemutande. Pamusoro pemaflange ese ari maviri pane slop, kazhinji, 1:6, iyo inoita kuti ave makobvu mukati uye matete kunze.
Nekuda kweizvozvo, inoshanda zvakanaka pakutakura mutoro pasi pekumanikidzwa kwakananga. Danda iri rine mipendero yakaderera uye kukwirira kwakakwirira kwechikamu chemuchinjikwa zvichienzaniswa nehupamhi hweflange.
Zvichibva pakushandiswa, zvikamu zveI-beam zvinowanikwa mumhando dzakasiyana-siyana dzekudzika, ukobvu hwewebhu, upamhi hweflange, huremu, uye zvikamu.
Chii chinonzi H Beam?
Iyo zvakare inhengo yechivakwa chakaita seH huru ine simbi yakakungurutswa. Matanda echikamu cheH anoshandiswa zvakanyanya muzvivakwa zvemabhizinesi nedzimba nekuda kwesimba rawo pakuyera huremu uye hunhu hwemakanika hwakanaka.
Kusiyana neI beam, H beam flanges hadzina inside inclination, zvichiita kuti kupinza kuve nyore. Maflange ese ari maviri ane ukobvu hwakaenzana uye akaenzana.
Hunhu hwayo hwepakati pezvikamu huri nani pane hweI beam, uye ine hunhu huri nani hwemakanika pahuremu hweyuniti imwe neimwe hunochengetedza zvinhu nemari.
Ndiyo inonyanya kufarirwa pakugadzira mapuratifomu, mezzanines, uye mabhiriji.
Pakutanga, matanda esimbi echikamu cheH nechikamu cheI akafanana, asi misiyano yakakosha pakati pematanda maviri aya esimbi inokosha kuziva.
Chimiro
Dara re h rakafanana nechimiro cheCapital H, nepo dara re I rakafanana neCapital I.
Kugadzira
Matanda eI anogadzirwa sechinhu chimwe chete, nepo H-beam ine maplate matatu esimbi akabatanidzwa pamwe chete.
Matanda eH anogona kugadzirwa kusvika pahukuru hupi zvahwo hwaunoda, nepo kugona kwemuchina wekugaya kuchiganhurira kugadzirwa kwematanda eI.
Maflange
Maflange esimbi eH ane ukobvu hwakaenzana uye akaenzana, nepo simbi yeI ine maflange akatetepa ane kutsvedza kwe1: kusvika 1:10 kuti akwanise kutakura mutoro zviri nani.
Ukobvu hwewebhu
Beam re h rine dandemutande rakakora zvikuru kana tichienzanisa nebeam re I.
Huwandu hwezvidimbu
Danda re h-section rakafanana nesimbi imwe chete, asi rine bevel apo maplate matatu esimbi anosunganidzwa pamwe chete.
Kunyange zvazvo danda reI-section risingagadzirwe nekusanganisa kana kusanganisa machira esimbi, rinongova chikamu chimwe chete chesimbi zvachose.
Huremu
Matanda eH anorema zvikuru kana tichienzanisa nematanda eI.
Kureba Kubva kuFlange Kuenda pakati peWeb
Muchikamu cheI, daro kubva kumucheto weflange kusvika pakati peWeb rakati wandei, nepo muchikamu cheH, daro kubva kumucheto weflange kusvika pakati peWeb rakati kurei kune chikamu chakafanana cheI-beam.
Simba
Danda re h-section rinopa simba rakawanda pahuremu hweyuniti nekuda kwenzvimbo yakachinjika yakagadzirwa zvakanaka uye chiyero chakanaka chesimba-ku-huremu.
Kazhinji, matanda eI-section akadzika kupfuura akafara, zvichiita kuti ave akanaka kwazvo pakutakura mutoro pasi pe local buckling. Uyezve, ane huremu hwakareruka kupfuura matanda eH-section, saka haazotore mutoro wakawanda semaH-beams.
Kuomarara
Kazhinji, matanda echikamu cheH akaomarara uye anogona kutakura mutoro unorema kupfuura matanda echikamu cheI.
Chikamu chakayambuka
Danda reI-section rine chikamu chakamanikana chakakodzera kutakura mutoro wakananga uye kumanikidzwa kwekukweshana asi harina kunaka pakukombama.
Kana tichienzanisa, danda reH rine chikamu chakafara kupfuura danda reI, iro rinogona kubata mutoro wakananga uye kumanikidzwa uye kuramba kutenderedzwa.
Nyore Yekushongedza
Matanda echikamu cheH anowanikwa nyore nyore pakuwelda nekuda kwemaflanges awo ekunze akatwasuka kupfuura matanda echikamu cheI. Chikamu chechikamu chedanda rechikamu cheH chakasimba kupfuura chikamu chedanda rechikamu cheI; saka chinogona kutora mutoro wakakura.
Nguva yeInertia
Nguva yeKusasimba kwedanda ndiyo inosarudza kugona kwaro kuramba kukotama. Kana rakakwirira, ndipo parinokotama zvishoma.
Matanda echikamu cheH ane maflange akafara, kuomarara kwakanyanya kwemativi, uye nguva yekusagadzikana kwakanyanya kupfuura matanda echikamu cheI, uye anodzivirira kukotama kupfuura matanda echikamu cheI.
Mapanhi
Danda reI-section rinogona kushandiswa kwenguva inosvika 33 kusvika 100 feet nekuda kwemiganhu yekugadzira, nepo danda reH-section richigona kushandiswa kwenguva inosvika 330 feet sezvo richigona kugadzirwa chero saizi kana kukwirira.
Zvehupfumi
Beam rechikamu cheH chikamu chinodhura zvishoma chine hunhu hwemakanika hunovandudza pane beam rechikamu cheI.
Kushandiswa
Matanda echikamu cheH akanakira nzvimbo dzekuvaka dzimba dzepamusoro-soro, mabhiriji, mapuratifomu, uye kuvaka zvivakwa zvekugara nezvemabhizinesi. Anoshandiswawo pakuvaka mapuranga anotakura mutoro, matiraki, uye maburi emota.
Matanda echikamu cheI ndiwo anoshandiswa kugadzira mabhiriji, zvivakwa zvesimbi, uye kugadzira mafuremu ekutsigira nemakoramu emaelevator, mahoist nema lift, trolleyways, matrailer, uye marori.
