He aha te mea te puranga hōhā?

Kei te whānui puranga hōhā whakamahia i roto i te hanga. Ko ratou porotakaroa hanganga āhua ngā paenga whakapakaritia e whai he diameter iti, me te tokomaha o te ngā wä roa, ki te diameter nui. Na inaianei e taea whakaaro tatou āhuatanga katoa o ratou whakamahinga.

I te kau, e whakamahia puranga hōhā i roto i te hanga o te mahuahua mahi mo te ārai o ngā aituā. riro ratou whakamahi kua tino nui i roto i turanga mahi me te soruzheniya mō whare. Ēnei hua i te taumata teitei e taea te whakanui ake i te kaha kawenga-te whanau o te turanga. I roto i te wahi o raro o te hanganga puranga hōhā i te toronga, e āwhina ki te whakapai ake i to ratou mahi i roto i te te whakamahi.

E whānui ēnei puranga whakamahia i roto i tono i reira te kaha nui o te turanga, ahakoa i roto i situ rawakore oneone. tukua ratou, i roto i te tahuri, whakaiti te utu o te mahi whakahaeretia, me te i roto i te hanganga o te whare iho. Kei te angitu whakamahia ratou i roto i te hanga, i roto i tawhiti e haere ana i te whakatū i tētahi whare, i reira e te tahi atu whare. tukua ratou ki a koe te hanga i te angitu o te hanganga i roto i ngā āhuatanga kōpipiri, ka kore e tūtohu ana ki te whakamahi i tetahi atu hangarau. A, no te mahi ki te turanga e hiahia ana koe ki te whakato a tawhio noa taua paipa puna rārangi, ai te tiaki mo te katoa o nga whare a tawhio noa i runga i te kawenga.

Ki te kōrero tatou e pā ana ki kōhao, mo e rua momo o puranga e whakaputaina ai e te taua hangarau. Heoi, i roto i te take o puranga werohia titau whakamahi o te taputapu motuhake he i roto i kōhao roto.

E tāuta puranga hōhā ki te whakamahi o te taputapu motuhake. I roto i te timatanga, kawea ana e ia i roto i kōhao, ki te tātai i te hohonu e hāngai ana i runga i te roa e hiahiatia ana o te puranga. Hoki taputapu whakamahia he tika ki te whiriwhiri i te diameter tika. A, no te haere mai te reira ki te whaiaro kōhao-, i konei he mea tika ki te whakamahi i te drill ringa. Next, Me koe ki te hanga i te formwork motuhake ki te waihanga poka. Ki te he te tino raru te oneone, a ka i roto i te tukanga o te mahi e kore e te ninii, e kore te mea e tika ana te formwork. Tenei momo o te whenua tino e ohie te mahi, no te mea e taea te ringihia tika te raima i muri i kōhao, engari i runga i te whenua tika hiahiatia ki te tāuta i te formwork. Na ka waiho e taea ki te hanga headroom mo puranga.

Me hanga whakaaro Special mo te formwork i roto i te kaupapa e te mea haere te puna i roto i te oneone meake. I roto i tenei take, ka taea e koe te whakamahi i ngā rauemi tuanui, takai ki te ngongo rahi e hiahiatia ana i mua. I tua atu, me kia whakaurua te kōhao anga o te whakaranu puranga heke mai, a ka ringihia raima hanga katoa, me tona hiri ki kia whakaritea takitahi i runga i nga āhuatanga o te turanga rānei. oti te puranga i tenei wā hōhā, a ka ka waiho reira taea ki te puta ki te wāhanga o te mahi hanga toe.

whakamahia tēnei momo o te hoahoa o turanga e tino whānui i roto i te hanga.
