Nā mea a me nā hoʻohana ʻana i nā ʻoki heleuma

ʻO ka heleuma bolt kahi mea hoʻohui koʻikoʻi i hoʻohana ʻia no ka hoʻopaʻa ʻana i nā hale, nā mea hana mechanical a i ʻole nā ​​​​mea hana ʻē aʻe ma ke kahua paʻa, a pono e loaʻa i kāna mea waiwai ka ikaika a me ka pale ʻana i ka corrosion e hōʻoia i ka paʻa a me ka palekana. ʻO nā mea o nā bolts heleuma ka mea nui:

● ʻO ke kila kalapona: ʻO nā bolts heleuma carbon steel ke ʻano maʻamau, a maʻa mau ka ikaika a me ka paʻakikī, a me ke kumu kūʻai haʻahaʻa. ʻO ka mea maʻamau no nā bolts heleuma kalapona he Q235B, akā hiki ke hoʻohana ʻia ʻo Q345 a i ʻole 16Mn, ʻoi aku ka ikaika.

● Alloy steel: Alloy steel heleuma bolts i kiekie ae ka ikaika a me ka corrosion kū'ē, kūpono no ke kaumaha hana, kiʻekiʻe wela a corrosive kaiapuni. ʻO nā mea kila kila maʻamau me 40Cr, 35CrMo a pēlā aku.

● Ke kila kila: Ua hoʻohana nui ʻia nā ʻōleʻa heleuma kuhili ʻole i ka haʻahaʻa kiʻekiʻe a me nā wahi corrosive, e like me ka ʻenekinia moana a me ka ʻoihana kemika, no ka maikaʻi o kā lākou pale ʻana i ka corrosion. ʻO nā mea kila kuhili ʻole maʻamau ʻo A2 (304) a me A4 (316).

Eia kekahi, he keleawe, aluminika a me nā mea ʻē aʻe o nā bolts heleuma, hoʻohana pinepine ʻia kēia mau mea no nā hanana kūikawā, e like me nā mea uila a i ʻole subway. Hoʻokaʻawale ʻia ka pae ikaika o nā bolts heleuma i 4.8, 6.8, 8.8, a me nā mea ʻē aʻe, a koho ʻia ka pae kūpono a me ka pae ikaika e like me nā ʻano hoʻohana like ʻole a me nā koi.

ʻO ka hoʻohana nui ʻana o nā bolts heleuma penei:

1. Hale paʻa: Hoʻohana mau ʻia nā heleuma no ka hoʻopaʻa ʻana i ke kumu o kahi hale e hōʻoia i ka hiki i ka hale ke lawe paʻa i kona kaumaha ponoʻī a me nā ukana waho. Hiki i ka hoʻohana ʻana i nā bolts heleuma ke hoʻonui i ka paʻa a me ka palekana o nā hale.

2. Paʻa makani Seismic: hiki ke hoʻohana pū ʻia nā kī heleuma no ka pale makani seismic. Inā loaʻa nā pōʻino kūlohelohe e like me ke olai a i ʻole nā ​​pōʻino makani, hiki i nā bolts heleuma ke hana i kahi hana i ka hoʻoponopono ʻana i ka hale, e hōʻemi i ka pōʻino a me ka hāʻule ʻana o ka hale, a me ka pale ʻana i ka palekana o nā limahana a me nā waiwai.

3. Hoʻololi i nā hale kahiko: I ka hoʻololi ʻana i nā hale kahiko, hiki i ka hoʻohana ʻana i nā bolts heleuma ke hoʻoikaika i ke ʻano o ka hale, e hoʻomaikaʻi i kona hiki ke hoʻōla a me ka makani, a hoʻonui i kona ola lawelawe.

4. Nā hoʻohana ʻē aʻe: hiki ke hoʻohana ʻia nā bolts heleuma no ka hoʻoponopono ʻana i nā alahaka, nā pale ala, nā mīkini nui a me nā lako, a me nā mea ʻē aʻe, e hōʻoia i kā lākou hana palekana a paʻa. He kuleana koʻikoʻi nā bolts heleuma ma ke kahua kūkulu a ʻo ia kekahi o nā mea pono no ke kūkulu ʻana i ke kūpaʻa a me ka palekana.
