Iphrofayili Yensimbi I Beam
Insimbi I Beam
I-I-beam iwuhlobo lwensimbi ene-cross-section enomumo othi "I", umumo wendiza ephambanayo we-I-beam, yingakho igama.
Uma kuqhathaniswa nama-engeli nama-H-beams anosayizi ofanayo, ama-I-beam anesisindo esilula ngakho-ke kulula ukuwakha.
Umumo we-cross-section kanye nensimbi yensimbi ye-I beam steel inquma ukumelana kwayo nokugoba nokusonteka kangcono kunamanye amaphrofayili ajwayelekile.
I-cross-section shape ye-steel I beam kulula ukuyifaka ngenxa ye-buckling yayo eguquguqukayo, ngakho-ke ingashiselwa ngokuqondile futhi isetshenziswe.
I-I-imishayo isetshenziswa kakhulu ezakhiweni ezihlukahlukene zokwakha, ubunjiniyela bebhuloho, ukukhiqizwa kwemishini kanye neminye imikhakha.
Ukucaciswa okujwayelekile
Uhlobo lokucaciswa kwe-I-beam lunqunywa ngokuyinhloko ngamapharamitha amabili: ubude (H) nokuqina okhalweni (b).Okulandelayo amamodeli ajwayelekile wokucaciswa kwe-I-imishayo:
1. Imodeli evamile kazwelonke: H × B × t1 × t2
2. Imodeli eyenziwe lula: H (ukhalo) × B (phansi) × C (isisu) × t (ukujiya okhalweni)
Phakathi kwazo, ukucaciswa okuvamile kwe-H-beam kukhona H100, H120, H140, H160, H200, H250, H300, H350, H400, H450, njll. I-B-beam ikakhulukazi inamamodeli afana ne-B63, B76, B89, njll. futhi imininingwane ye-C-beam mincane.
Sinesipiliyoni samashumi eminyaka ekuthekeni kwensimbi futhi singakunikeza ngezinhlobo ezahlukene zensimbi yephrofayili.Uma imininingwane oyidingayo ingashiwongo kuleli khasi, sicela usithinte ukuze uthole ukuxhumana okwengeziwe.
