Mark raima kōeke ranei? Me pēhea te ki te whakarōpū te raima i roto i te hanga o to koutou ake te kāinga?

Te nuinga ngā o nga whare takitahi whakarōpū raima, te whakamahi i te wā pērā i te kōeke raima. Heoi, i tenei rauemi hanga kua tetahi āhuatanga - te piha haapiiraa. Ki te mea kua hono taua selectivity, a he aha te mea te rerekētanga i waenganui i te tohu, me te piha haapiiraa?

Concretes Ko te tino noa, faaau ore, hanga rauemi, me te rua o nga whakamahi, i muri i te rauemi wai i roto i te ao. Kei te whiwhi he kohatu horihori, hua i te solidification o te puranga ōrite i konatunatua i roto i etahi hanganga o ngā wāhanga pērā i sima, wai, taima kaihanga me / ranei.

He he rerekē te maha tika nui o concretes rerekē i roto i te whakaaro, a i roto i te ahua me te momo o te kōpaki matua me taima - me tikanga maoa, me tona hanganga. Heoi, ahakoa tenei momo katoa o te raima, i reira e toru anake ngā āhuatanga kounga taketake e kua whakamahia i roto i te tātai mo te hoahoa o ngā whakaurunga heke mai - te kaha, resistance wai me te ātete huka. Hei whakatau i nga moni o enei nui āhuatanga o raima , a i whakaurua te ariā o te waitohu me te kōeke.

Hei tauira, whānui e whakamahia ana i roto i te whare takitahi mo te whakaarahanga o rerekē turanga raima tohu 200 no ki te piha haapiiraa B 15 me te huka - F75-F100 me parewai - W2-W4.

O te akoranga, te tuatahi o te pātai katoa te panga o te mea e te kōeke o te raima, me te aha, ko tona rerekētanga i te piha haapiiraa.

Me tīmata tatou ki, nga akomanga raima me waitohu e anake āhuatanga kaha, heoi, i te tahi mau mita i roto i te tono mahi.

Ko Brand kaha taupū tau paerewa i takea mai i ngā whakamātautau taiwhanga me te kaha shock. I roto i te mau parau te tahi atu, te uara o e whakatau he aha te kawenga aunoa mōrahi e taea te tu mata henemita tapawha. Ka rite ki raima ahu ki te whakapiki ake i runga i te wā, te kaha, e ngohengohe ki tauira tohutoro (maka poraka ki te taha o te 10 henimita) i te tau o te matuatanga o kore e iti iho i 28 ra te whakamātautau. Ngā tohu raima - i roto i te whānui o i M800 ki M50 (ki te whakanui ake i kiato i te hua i roto i te taupū tau). e kore hoki hanga takitahi te whakamahia raima runga ake kōeke 400.

uara tohu Heoi, kī kaha te ko te taiwhanga, mai i roto i te mahi pānga reira he maha o ngā āhuatanga destabilizing pērā i raruraru i roto i te ahumahi hangarau, te onepu me te wai kounga ōritengakore, me te huringa tautuhinga whakapanga tikanga. arata'i tenei katoa ki te hekenga i roto i ngā āhuatanga kaha. A tenei hapa ranei tau whakarea o rerekētanga ko te rerekētanga matua i waenganui i te piha haapiiraa o te raima i runga i tona waitohu. Tino te reira noa te kaha tūturu ki te iti (5%) ine. I roto i te mahi o te piha haapiiraa raima - whakamahia te uara tātai nui te (i roto i te rerekē ki te tohu) i roto i te hoahoa o ngā tipu heke mai. Whanganga i MPa, a kua whakaritea GOST 26633-85. I roto i te katoa i reira e ono o ngā akomanga kaha mai i te 3.5 i roto i ki te 60 i roto i.

Ko te āhuatanga kounga e whai ake nei - resistance wai me te huka resistance - Whakaröpütia anake i runga i tohu.

Mark raima, faaite Ko ano hoki te huka he uara taiwhanga. tohu te reira i te whakamātautau rahinga tohu tau mōrahi i roto i i i raro i te tauira i ki whakatio-koero. whakaritea Frost waru tohu i roto i te whānuitanga o i 50 F ki 500 F.

Ko tētahi atu kounga āhuatanga - kōeke o te raima i runga i resistance wai. Hoki te tapanga o te wuru tono e ono ngā kōeke mai i 12 W ki W2, e ko te uara mōrahi o te pēhanga wai i nei e kore e taea ki te haere te wai (i raro ki tikanga whakamātautau paerewa) te tauira tohutoro.
