Ukuze kuncedwe umakhi: ubunzima kunye nobungakanani I-msebe

Enye yeentlobo uthandwayo but is a ubungakanani cross-somhlathi ileta kabini-lubangelwe T. I-beam umqadi-ezifana ixhomekeke injongo yawo isusela ukusuka neemitha ezine ukuya 12.

Beam kabini-tee: Iindidi

Iintlobo iinkangeleko yahlulwe eziqhelekileyo nezemfundo eneemfuno ezizodwa ezilungiselelwe ukusebenza phantsi kweemeko ezithile (ukuba monorails isixhobo unyanzeliso shaft). Kuxhomekeka ubude yabucala kunokuba mbini, ezininzi mbini, ngokomthamo okanye multiple eseleyo nge (5% ubunzima ibhetshi), kwaye off-yobu-. Direct Isisombululo I-beam ekwafanekisa umgama ukusuka kwenye ekupheleni engaphandle besiya kwelinye kwithala.

I-imiqadi, ngokuxhomekeke iintlobo kufuneka umahluko kakhulu ngobukhulu. Umzekelo, ububanzi kweshelfu iyaguquguquka, ekubeni inxulumene ngqo ukwakheka kwalo (ubuso bathanda okanye parallel). Kwakhona, I-imiqadi ahluka kwizinto eziphathekayo ukusuka apho kwenziwa, kuba ichaphazela ukusetyenziswa zabo kwiindawo ezahlukeneyo (ngentsimbi ezizodwa, carbon okanye asezantsi ingxubevange ziintsimbi, ezi zodwa kwezixhaso ngentsimbi eshushu-liqengqiwe).

NeMigangatho I-echweliweyo

Kukho imigangatho eziliqela yavuma ukuba ukudibanisa ubungakanani I-beam kuxhomekeke indlela wokwenziwa kwalo kunye nokusetyenziswa. Ngokomzekelo, xa ngentsimbi eshushu golokongqo I-neyophahla abasezantsi gauge iveliswayo ezinkulu parameters - imilinganiselo ngqo kwicandelo emnqamlezweni, umyinge we-1 m reference amaxabiso imithwalo ubuninzi ku nangeempahla ezibukhali zesinyithi.

Iqengqwa beam ngqo ukwahlula yesiqhelo (B enombhalo) okanye nokuchaneka eliphezulu (enombhalo B).

imigangatho ethile elawulwa dimensions mix I-Imiqadi, apho komele ejongene parallel, intsimbi kushushu ezityikitywe, intsimbi ekhethekileyo, ezinye iintlobo I-echweliweyo ezikhethekileyo yaye mna-echweliweyo ziveliswa kubenzi iinkcukacha.

Kwimeko nganye kwezi ekhoyo I-beam ukulawula nabadla elikhankanyiweyo ubungakanani (ukuphakama kwayo, ubukhulu ububanzi kunye umndilili esisangqa, Ebubanzini bodonga, lo radii amagophe ongaphakathi neeshelufa), ubunzima wemitha yomgama (kg) kwaye inani kweemitha kwitoni I-echweliweyo nganye.

iimfuno GOST ukuya I-ug 36

Umzekelo, onomdla thina ubungakanani kabini-T-beam apho iindwendwe 8239-89 olumiswe lwagqitywa. Imizobo yezi profiles zidla kubonelelwa ngomgangatho kwaye ithwale ulwazi imvelaphi oluneenkcukacha, wakha phezu Ubukhulu zejiyometri umqadi. Nabo ke, bahambelana iimpawu zomzimba yenkangeleko, kubalulekile ukuba isicelo yayo.

Umgangatho emiselweyo iparameters uphawu olu hlobo profile, nto leyo eqhelekileyo ukuba zombini kubavelisi kunye nabathengi. Ngenxa yoko, I-neyophahla 36. Imilinganiselo: ukuphakama - 36 cm, ububanzi ezishelfini - 14.5 cm, udonga ubukhulu - 0,75 cm, ububanzi avareji kweshelfu - 12.3 mm, apho ukuqoqa radius engaphakathi kufuneka kube ngaphezu 1.4 cm, ezishelifini ukuqoqa - 0.6 cm.

Uhlobo Special M I-echweliweyo zisetyenziswa lokulawula milenge ezihamba kunye ukhwelisa, ukususela Ebubanzini ezishelfini yandiswe xa kuthelekiswa ne eqhelekileyo.

Kwakhona bona iitafile kwincwadi eqhelekileyo, sazi kakuhle ubunzima nganye imitha (womxhuzulane ezithile) I-umqadi 36, nto leyo usoloko umnye kwaye kuthetha 48.6 eekhilogram.
