Kutanthauzira kwazinthu ndi kapangidwe kake
Nangula wopangidwa ndi 7 amatchedwa chifukwa chakumapeto kwa bolt sikung'ambika mu "7". Ndi imodzi mwamitundu yofunika kwambiri ya nangula. Kapangidwe kake kamaphatikizira thupi lopindika ndi mbewa yooneka ngati L-L. Gawo la Hook limayikidwa m'manda owerengeka ndikulumikizidwa ndi zida kapena chitsulo kudzera mu nati kuti mukwaniritse mawonekedwe okhazikika.
Zida ndi zinthu zina
Zinthu:Nthawi zambiri amagwiritsidwa ntchito ngati q235 yachitsulo (mphamvu yolimba, mtengo wotsika), q345 yotsika zitsulo (mphamvu yayikulu) kapena 40cr mphamvu yolimba (yotentha) kuteteza) kuteteza).
Mawonekedwe:
- Kukhazikitsa kosinthika: kapangidwe ka zokongoletsa kumawonjezera mphamvu yokhazikika ya konkriti ndipo ndi yoyenera pokonza zida zazing'ono komanso zapakatikati;
- Kukoka magwiridwe antchito: Kuchita masewera olimbitsa thupi pakati pa mbedza ndi konkriti kumayimitsa mphamvu yolimbikitsa;
- Kukhazikika: Imagwirizana ndi miyezo yadziko monga GB / T 799, ndipo zomwe zimapangitsa kuti zisachitike kuchokera m16 mpaka m56.
Ntchito ndi Zochita Zofunika
Ntchito:
Konzani zitsulo za chitsulo, zigawo za nyale zamsewu, ndi zida zazing'ono;
Nyamula katundu wokhazikika, monga mafelemu ndi mabatani omenyera.
Scenario:
Maulamuliro a Kandunal (nyambo zamtchire, zizindikiro zapamsewu), mafakitale owoneka bwino, ndi zida zapakhomo (monga zowongolera zapanyumba zosanja).
Kukhazikitsa ndi kukonza
Kukhazikitsa:
Mabowo osungirako mabowo a konkriti yonkriti, ikani mawonekedwe 7 opangidwa ndikuponya;
Mangani zida ndi mtedza ndikusintha mulingo mukazikhazikitsa.
Kukonza:
Onani kulimba kwa mtedza pafupipafupi, ndipo malo owonongeka omwe akuyenera kuyenera kubwezeretsedwa kuti mutetezedwe.
Malingaliro ogula
Sankhani zida molingana ndi katundu: Q235 ndi yoyenera pazinthu wamba, Q345 ndizoyenera katundu wambiri (monga milatho);
Kutalika kwa mbedza iyenera kukwaniritsa zofunikira za maliro a konkriti (nthawi zambiri ma 1 nthawi ndi bolt).
Kuyerekeza ndi kuwongolera kwa ma angula akulu atatu
| Mtundu | Njonyezi ya 7 yooneka | Kutentha kwambiri mbale | Ambulera yonyamula namber |
| Ubwino Wopindulitsa | Kukhazikika, mtengo wotsika | Kutalika Kwambiri Kwambiri, Kukana Kugwedeza | Kusinthasintha kwamphamvu, zachuma |
| Katundu woyenera | 1-5 matani | 5-50 matani | 1-3 matani |
| Zochitika zokhazokha | Magetsi a mumsewu, zitsulo zopepuka | Milatho, zida zolemera | Nyumba zosakhalitsa, makina ang'onoang'ono |
| Njira Yokhazikitsa | Kukula kwa Nutge + | Kuthira + kuwotcha pad | Kukula kwa Nutge + |
| Kuchuluka kwa kuchuluka | Electroorvalvalvalvalving (wamba) | Kutentha kwambiri + kupaka utoto (kukana kwamphamvu) | Gwervanated (wamba) |
Malingaliro osankhidwa:
Zosowa zachuma: Maambulera onyamula mangures amakondedwa, poganizira mtengo komanso ntchito;
Zosowa zolimba: Anangula obiriwira ndi chisankho choyambirira cha zida zolemera;
Zochitika Zotsimikizika: Nthambi zopangidwa ndi 7 ndizoyenera pazosowa zofunikira kwambiri.

Electro-galvanized kukula kwa mbedza
Zopangidwa ndi kaboni ka kaboni ndi zinthu zina, pamwamba pake pamwamba ndi electro-yogawidwa, ndipo makulidwe okutidwa ndi ma c1a (abulamu)
Zithunzi za zinc
Mutu wa Bown Bolt ali ndi chingwe chozungulira kuti chiwonjezere malo olumikizirana ndikuwonjezera zovuta (muyezo GB / T 5787, GB / T 5789). Zodziwika bwino m6-m30, zinthu zina zambiri q235 kapena 35cmo, pamwamba poloza kapena kudetsa.
