He aha te H-Beam me te I-Beam?

He aha te H-Beam?

H-hikuHe rauemi anga hangarau tēnei, he kaha ki te kawe kawenga, he māmā hoki te hoahoa. He tino pai mō ngā hanganga maitai hou he whānui ngā whāwhā me ngā kawenga teitei. Ko ōna whakatakotoranga paerewa me ōna painga miihini e akiaki ana i te auahatanga hangarau hangarau i roto i ngā mara o te hanga, piriti, pūngao, me ētahi atu.

He aha te I-Beam?

Kurupae-IHe rauemi hanganga piko kotahi-angihanga ohanga tēnei. Nā te iti o te utu me te ngāwari o te tukatuka, he whānuitia te whakamahinga i roto i ngā āhuatanga pēnei i ngā kurupae tuarua i roto i ngā whare me ngā tautoko miihini. Heoi, he iti iho i te kurupae-H te ātete ki te takahuri me te kawe kawenga maha-angihanga, ā, me tino hāngai te kōwhiringa ki ngā whakaritenga miihini.

Te Rerekētanga o te H-Beam me te I-Beam

Rerekētanga nui

H-HisHe whakarara, he ōrite te matotoru o ngā parirau (ngā wāhanga whakapae o runga, o raro) o te kurupae-H, e hanga ana i te tapawhā "H" te āhua. He tino pai te ātete piko me te ātete hurihuri, e pai ai mō ngā hanganga matua e mau ana i te kawenga.

I-BeamHe whaiti ake ngā taha o roto o te kurupae-I, he whānui ake hoki i waho, he pari (ko te tikanga he 8% ki te 14%). He āhua "I" te āhua o te tapahanga whakawhiti, e aro ana ki te ātete piko kotahi te ahunga me te penapena, ā, he maha ngā wā ka whakamahia mō ngā kurupae tuarua he māmā te utaina.

Whakataurite taipitopito

H-His:maitai āhua-HHe hanganga pouaka ātete-torsion tēnei, he mea hanga mai i ngā parirau whakarara whānui, matotoru hoki, me ngā tukutuku poutū. He whānui ngā āhuatanga miihini (he pai te piko, te torsion, me te ātete pēhanga), engari he nui te utu. E whakamahia ana i roto i ngā āhuatanga matua e mau ana i te kawenga pēnei i ngā pou whare teitei, ngā tuanui wheketere whānui-whānui, me ngā kurupae kerēni taumaha.

I-Beam:Ngā hihi-IHe penapena rauemi, he whakaiti hoki i ngā utu nā te hoahoa o te pari o te flange. He tino whai hua ēnei ina pikohia ki te taha kotahi, engari he ngoikore te ātete ki te takahuri. He pai mō ngā wāhanga tuarua he māmā te utaina pērā i ngā kurupae tuarua o te wheketere, ngā tautoko taputapu, me ngā hanganga rangitahi. He otinga ōhanga tēnei.

Ngā horopaki tono o te H-Beam me te I-Beam

H-His:

1. Ngā whare tino teitei (pērā i te Pourewa o Shanghai) – ka ātete ngā pou whānui ki ngā rū whenua me te hau kaha;
2. Ngā tuanui o ngā tipu ahumahi whānui – he ātete piko teitei hei tautoko i ngā kerēne taumaha (50 tāne me runga ake) me ngā taputapu tuanui;
3. Hanganga pūngao – ka tu atu ngā anga maitai o te pūwero hiko wera ki te pēhanga me ngā pāmahana teitei, ā, ka tautoko ngā pourewa o te tāhū hau i te wiri o te hau.
4. Piriti taumaha – ka ātete ngā taura mō ngā piriti whakawhiti-moana ki ngā kawenga hihiri o ngā waka me te waikura o te wai moana;
5. Mīhini taumaha – me whai anga ātete ki te takahuri me te ngenge mō te keri i ngā tautoko waipēhi me ngā takere kaipuke.

I-Beam:

1. Ngā purlin tuanui whare ahumahi - Ka tautoko pai ngā flange koki i ngā pereti maitai pania tae (whānui <15m), ā, he 15%-20% te iti iho o te utu i ngā kurupae-H.
2. Ngā tautoko taputapu mama - Ka tutuki i ngā ara kawe me ngā anga papa iti (te kaha kawenga <5 tāne) ngā whakaritenga kawenga pumau.
3. Ngā hanganga rangitahi - Mā ngā kurupae hanganga me ngā pou tautoko whare whakaaturanga ka tere te huihui me te wetewete, ā, ka iti ake te utu.
4. Ngā piriti kawenga iti - Ko ngā piriti kurupae tautokona ngāwari i runga i ngā rori tuawhenua (te whānuitanga <20m) ka whakamahi i tō rātou ātete piko utu-pai.
5. Ngā turanga mīhini - He nui te ōwehenga pakari-ki-taumaha o ngā turanga taputapu mīhini me ngā anga mīhini ahuwhenua.
