Kutheni uninzi lwemibhobho yentsimbi iimitha ezi-6 kwisiqwenga ngasinye?

Kutheni uninziimibhobho yentsimbiIimitha ezi-6 kwisiqwenga ngasinye, kuneemitha ezi-5 okanye iimitha ezisi-7?

Kwiiodolo ezininzi zokuthengwa kwentsimbi, sihlala sibona: “Ubude obuqhelekileyo bemibhobho yentsimbi: iimitha ezi-6 kwisiqwenga ngasinye.”

Umzekelo, imibhobho edityanisiweyo, imibhobho eyenziwe ngamazimba, imibhobho yesikwere kunye noxande, imibhobho yentsimbi engenamthungo, njl. njl., ubukhulu becala isebenzisa i-6m njengobude obuqhelekileyo beqhekeza elinye. Kutheni iimitha ezi-5 okanye i-7 yeemitha? Lo ayingomkhwa kuphela weshishini, kodwa sisiphumo sezinto ezininzi.

Iimitha ezi-6 "ubude obusisigxina" kwimibhobho emininzi yensimbi

Imigangatho yentsimbi yesizwe emininzi (umz., GB/T 3091, GB/T 6728, GB/T 8162, GB/T 8163) icacisa ngokucacileyo: Imibhobho yentsimbi inokuveliswa ngobude obusisigxina okanye obungaguqukiyo.

Ubude obumiselweyo obuqhelekileyo: 6m ± ukunyamezela. Oku kuthetha ukuba iimitha ezi-6 zezona zimkelwa kuzwelonke kwaye zixhaphakile ubude besiseko.

Ukumiselwa kweZixhobo zoMveliso

Imigca yokuvelisa imibhobho edityanisiweyo, iiyunithi zokwenza ityhubhu yesikwere kunye noxande, iiyunithi zokusila ezibandayo, oomatshini bokulungisa, kunye neenkqubo zombhobho oshushu oqengqelekayo-ubude obusisigxina—iimitha ezi-6 bobona bude bufanelekileyo kuninzi lwezixhobo zokusila kunye nemigca yokwenza imibhobho edityanisiweyo. Kwakhona bubude obulula ukulawula imveliso ezinzileyo. Ubude obugqithisileyo bubangela: ukuxinezeleka okungazinzanga, ubunzima bokudibanisa / ukusika, kunye nokuguquguquka komgca. Ubude obufutshane kakhulu bukhokelela ekunciphiseni imveliso kunye nokwanda kwenkunkuma.

Imiqobo yezothutho

imibhobho yeemitha ezi-6:

• Ziphephe izithintelo zobukhulu obugqithisileyo
• Ukuphelisa imingcipheko yezothutho
• Akufuni mvume zikhethekileyo
• Ukuququzelela ukulayishwa / ukothula
• Nikela ngeendleko eziphantsi

7–8-yemitha yemibhobho:

• Ukwandisa ubunzima bezothutho
• Ukwandisa ingozi enkulu
• Zinyuse kakhulu iindleko zolungiselelo

Iimitha ezi-6 zilungele ukwakhiwa: inkunkuma ephantsi, ukusika ngokuthe ngqo, kunye neemfuno eziqhelekileyo zecandelo le-post-cut cut (3 m, 2 m, 1 m).

Uninzi lweemeko zofakelo kunye nokucubungula zifuna izahlulo zemibhobho phakathi kwe-2-3 yeemitha.

Ubude beemitha ezi-6 bunokunqunyulwa ngokuchanekileyo kwi-2 × 3 m okanye 3 × 2 m amacandelo.

Ubude beemitha ezi-5 buhlala bufuna ukongezwa kwe-welding kwiiprojekthi ezininzi;

Ubude beemitha ezisi-7 bunzima ukuthutha kunye nokuphakanyiswa, kwaye kulula kakhulu ukugoba ukuguqulwa.

Ubude beemitha ezi-6 buye baba ngowona mgangatho uqhelekileyo wemibhobho yentsimbi kuba idibana ngexesha elifanayo: imigangatho yelizwe, ukuhambelana komgca wemveliso, ukuthutha ukuthutha, ukusetyenziswa kokwakhiwa, ukusetyenziswa kwezinto eziphathekayo, kunye nokunciphisa iindleko.
