Kōkua mākou i ka honua e ulu nei mai ka makahiki 1983

ʻO ka mea maʻamau maʻamau, no ke aha mākou e koho ai i ka Q355.

Nīnau nā mea kūʻai aku he nui iaʻu e pili ana i nā mea o ka hae, a me nā hoa aloha he nui e kūʻai ana i ka scaffolding kinona mai ʻike i ke kumu a mākou e hoʻohana ai iā Q355 (Q345) i ke koho ʻana o nā mea o ka hae, a he nui hoʻi nā hae me ka stamp kila Q355 i kahakaha ʻia i ka mākeke, akā ua hui pū ʻia me nā mea Q235. No nā mea i luna, ʻo mākouRapid Scaffolding (ʻenehana) Co., Ltd.., ma ke ʻano he luna hoʻoponopono o ka "scaffold safety technic safety specifikasi", e hāʻawi iā ʻoe i kahi kālailai mai ke ʻano o ke kūkulu ʻana, e wehewehe i nā pilikia o ka "Q235 material standard"!

ʻO ka mea mua, e wehewehe wau i ka manaʻo o Q355 a me Q235.

ʻO Q345 (Q355) kahi ʻano kila, kahi kila hao haʻahaʻa. Hoʻohana nui ʻia i nā Alahaka, nā kaʻa, nā moku, nā hale, nā moku kaomi, nā pono kūikawā, a pēlā aku. "Q" ʻo ia hoʻi ka ikaika hua, a ʻo 345 ka manaʻo o ka ikaika o kēia kila. aia 345MPa.

Kāhea ʻia ʻo Q235 mea kila kalapona maʻamau ʻo A3 kila. ʻO ka papa kila kalapona maʻamau kahi ʻano kila. ʻO Q ka palena o ka hāʻawi o kēia ʻano mea, a ʻo 235 ma ka hope e pili ana i ka waiwai o kēia ʻano. mea, aia ma kahi o 235MPa.

Inā ʻo Q235 nā mea maʻamau o ka scaffold laka apo, ʻo 87% wale nō ia o ka Q355. ʻO ka hiki ke hana o ke kūlana he 90% o ka hiki ke hāpai ʻia, ʻo 47.4kN ia. Inā hoʻololi ʻia nā mea o ka hae i Q235, ʻo ke kumu hoʻohālikelike / ʻae ʻia ka hiki ke lawe ʻia o ka hae = 47.4 / 46.1 = 103%, i ʻoi aku i ka hiki ke hāpai ʻia a he mau weliweli palekana paha.

E like me kā mākou a pau e ʻike nei, ʻo ka ʻenekini scaffolding kekahi o nā kumuwaiwai nui he ʻumi o ka weliweli i ka hana ʻenekini, a ʻo ke kūlana ke koʻokoʻo ikaika nui i ka ʻōnaehana laka scaffold, no laila i ke koho ʻana o nā mea, pono mākou e nānā pono
