Indlela ukukhetha isiteshi

Namuhla singaba uqinisekise ukuthi imikhiqizo metal - bayingxenye yezimpilo zethu, ngaphandle kwabo besingeke sikwazi ukunikeza khona ukhululekile, ukubeka okuthembekile uhlelo nezokuxhumana, ukuthuthukisa ubuchwepheshe ukukhiqizwa, njll

Metal wasipha umuzwa wokulondeka, Ngakho-ke, ukuze sicabange ukungezwakali kwawo ekuphileni kwebantfu akunakwenzeka. Kuyinto izindawo engacabangeki nezezimboni ngaphandle ukusetshenziswa kwemikhiqizo ezenziwe metal. Omunye izliderov metal iyinkampani TD Chermetkom okuyinto batusa ukusebenzisa amasevisi.

On Kwimakethe ukwakhiwa kuphezulu kakhulu imikhiqizo metal ethandwa, ezifana sill.

Amabha Channel Iphrofayela ngokuthi izakhi metallic kwesakhiwo kanye "U" - ezimise cross-section. Iziteshi abaluleke kakhulu ekwakheni izakhiwo steel, iyiphi wizadi izoqinisekisa ukuthi bayadingeka ekwakhiweni, ngithabatha iningi umthwalo. Iziteshi avame ukusetshenziswa ukwakhiwa multi-storey izakhiwo, ukuzisebenzisa ukuze agcizelele izindonga zangaphandle kanye kwangaphakathi, ebaqinisa. By the way, iziteshi zingaqiniswa struts isakhiwo.

Ukukhuluma ezicashile lobuchwepheshe, kungaba kuqashelwe ukuthi isiteshi steel ihlukaniswe izinhlobo eziningana ngokuvumelana uhlobo yokukhiqiza:

- ashisayo (ukusetshenziswa okushisa aphakeme phakathi ukukhiqiza, roll noma i-carbon steel kwesakhiwo);

- ekhethekile, elisetshenziswa isakhiwo umshini nemoto;

- equilateral Lwalugobile (profile siko eguqa umshini);

- ibheke ngokungalingani. parallel sill isici okuthiwa emashalofini amabili angase abe ubuso parallel noma ubhekene ne eyehlelayo.

Ngo womshini U-izigaba ukukhiqiza workpiece metal 12 metres ubude. Lapho ekhetha isiteshi ngokuzimela, kulula ukuba ulahleke - izinhlobo eziningi kangaka kwalo mkhiqizo ukhona. Nakani yokuthi nemigoqo isiteshi ekhiqizwa ephawulwe. Ngokuvamile kusho ibanga phakathi emashalofini umkhiqizo, okungukuthi inombolo - ibanga ngamasentimitha komunye eshalofini kwenye.

Ukuze sikhethe kahle odinga ukukwazi isiqu izici sill kanye nomklamo ngawo ekhethiwe. Metal, kusukela lapho umkhiqizo kumele izinga okusezingeni futhi iqine, ngakho ukuthenga izakhi ezibalulekile metal izakhiwo izinhlangano othembekile kangcono.
