Hoʻohana maʻamau ka ʻike kumu o nā mea hoʻopaʻa

1. Hoʻohana nui ʻia nā mea hoʻopili maʻamau:heleuma wedge(ETA WEDGE ANCHOR), nā lāʻau kaula, kī hex, nati hex, mea holoi palahalaha, pale paʻi kiʻi kiʻi

2. Lepili o nā mea hoʻopaʻa

E pili ana ka M6 i ke anawaena inoa d o ka milo (ka anawaena nui o ka milo)

14 e pili ana i ka lōʻihi o ka milo kāne L o ka milo

E like me: hex head bolt M10*1.25*110

ʻO ka 1.25 e pili ana i ka pitch o ke kaula, a pono e kaha ʻia ka milo maikaʻi. Inā haʻalele ʻia, e hōʻike ana ia i kahi kaula koʻikoʻi.

3. Ka pae hana o na mea paa

Hoʻokaʻawale ʻia nā māka hana Bolt ma mua o 10 mau māka e like me 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, a me nā mea ʻē aʻe. ʻO ke kila kalapona waena a ua mālama ʻia i ka wela (quenching, tempering, etc.) ahi), i ʻike mau ʻia ʻo nā bolts ikaika kiʻekiʻe, a ʻo nā mea ʻē aʻe i kapa ʻia he mau bolts maʻamau. ʻO ka hōʻailona papa hana bolt he ʻelua ʻāpana o nā helu, e hōʻike ana i ka waiwai ikaika tensile nominal a me ka ratio ikaika o ka mea bolt. ʻO ka helu ma mua o ka helu decimal he 1/100 o ka palena ʻoi aku o ka ikaika o ka mea, a ʻo ka helu ma hope o ka helu decimal he 10 ka nui o ka ratio o ka palena hoʻohua i ka palena ikaika tensile o ka mea.

No ka laʻana: pae hana 10.9 mau pahu ikaika kiʻekiʻe, ʻo kona ʻano:

1. ʻO ka ikaika tensile nominal o ka mea bolt hiki i 1000MPa;

2. ʻO ka lākiō hua o ka mea bolt he 0.9;

3. Hiki i ka 1000 × 0.9 = 900MPa ka ikaika hāʻawi inoa o ka mea bolt;

ʻO ke ʻano o ka papa hana bolt he kūlana honua. Loaʻa ka hana like o nā bolt o ka papa hana like me ka nānā ʻole i ka ʻokoʻa o kā lākou mau mea a me nā kumu. Hiki ke koho wale ʻia ka papa hana no ka hoʻolālā ʻana.

Hoʻokaʻawale ʻia ka papa hana o ka nati i 7 mau māka, mai ka 4 a hiki i ka 12, a ʻo ka helu e hōʻike ana i ka 1/100 o ke koʻikoʻi liʻiliʻi i hiki i ka nati ke kū.

Pono e hoʻohana pū ʻia nā māka hana o nā bolts a me nā nati, e like me nā bolts grade 8.8 a me nā nati papa 8.
