He aha nā bolts ikaika kiʻekiʻe?
Hiki ke kapa ʻia nā bolts me ke kila ikaika kiʻekiʻe a i ʻole e koi ana i ka preload nui. Hoʻohana pinepine ʻia nā wili hoʻouna kiʻekiʻe no ka hoʻopili ʻana i nā alahaka, nā ala hao, nā mea uila kiʻekiʻe a me nā mea uila kiʻekiʻe. ʻO ka haʻihaʻi o kēia ʻano bolt ka hapa nui. ʻO nā wili ikaika kiʻekiʻe i hoʻohana ʻia i nā mea hana kiʻekiʻe kiʻekiʻe e koi i ka prestressing nui e hōʻoia i ka sila ʻana o ka ipu.
ʻO ka ʻokoʻa ma waena o nā bolts kiʻekiʻe a me nā bolts maʻamau:
1. Nāʻokoʻa o nā mea maka
Hana ʻia nā bolts ikaika kiʻekiʻe i nā mea ikaika kiʻekiʻe. ʻO nā wili, nā nati, a me nā mea holoi o nā wili ikaika kiʻekiʻe i hana ʻia me ke kila ikaika kiʻekiʻe, hoʻohana mau ʻia i 45 # kila, 40 boron steel, a me 20 manganese kila. Hana ʻia nā kī maʻamau me ke kila kalapona maʻamau me ka mālama ʻole ʻana i ka wela.
2. Nā ʻokoʻa o nā pae ikaika
Hoʻohana nui ʻia ka hoʻohana ʻana i nā bolts kiʻekiʻe, me ʻelua mau pae ikaika i hoʻohana mau ʻia: 8.8s a me 10.9s, me 10.9 ka hapa nui. Pono ka pae ikaika o nā bolts maʻamau, ma ke ʻano he 4.4, 4.8, 5.6, a me 8.8 pae.
3. Nā ʻokoʻa o nā ʻano ikaika
ʻO nā pili bolt maʻamau e hilinaʻi i ka pale ʻana o ke koʻokoʻo bolt a me ke kaomi ʻana o ka paia o ka lua e hoʻouna i ka ikaika ʻoki, ʻoiai ʻaʻole i loaʻa ka ikaika kiʻekiʻe o nā bolts kiʻekiʻe, akā hoʻopili pū kekahi i ka ikaika pre tension nui i nā bolts. e hana ana i ke kaomi hoʻomalu ʻia ma waena o nā ʻāpana hoʻohui, a pēlā e hana ai i ka ikaika frictional nui e kū pono ana i ka ʻaoʻao wili.
4. Nā ʻokoʻa i ka hoʻohana ʻana
ʻO nā pilina paʻa o nā mea nui o nā hale kūkulu hale i hana maʻamau me nā bolts ikaika kiʻekiʻe. Hiki ke hoʻohana hou ʻia nā bolts maʻamau, ʻoiai ʻaʻole hiki ke hoʻohana hou ʻia nā bolts kiʻekiʻe. Hoʻohana mau ʻia nā bolts ikaika kiʻekiʻe no nā pilina paʻa.
