Concrete Screws vs Nangula: Osati Njira Yosavuta Yosinthira
M'ma projekiti ambiri, zomangira za konkriti ndi anangula zimatengedwa ngati njira zosinthira.
Papepala, onsewa amagwiritsidwa ntchito pokonza konkire - koma pamalopo, amachita mosiyana kwambiri.
Nkhani siili "yabwino" komazomwe munthu amachita modalirika pamikhalidwe inayake.
Kuchokera kwa ogwira ntchito yoyika ndi ndemanga zogawa, kusankha kolakwika pakati pa njira ziwirizi zomangirira ndi chimodzi mwazomwe zimayambitsa:
Malumikizidwe otayirira pambuyo kukhazikitsa
Zolephera-zotuluka mosayembekezereka
Kuwonjezeka kwa nthawi yogwira ntchito chifukwa cha kukonzanso
Bukuli likugogomezera kwambirizenizeni-padziko lonse lapansi, osati zolemba zokha.
Momwe Zopangira Konkriti Zimagwirira Ntchito
Zomangira za konkriti zimadaliraulusi-kupanga chibwenzi.
Pambuyo pobowola bowo loyendetsa ndege:
Zowononga zimadula khoma la konkriti
Ulusi umapanga kukangana ndi kulumikiza makina
Fumbi limachotsedwa mu dzenje
Palipalibe mphamvu yowonjezeraokhudzidwa.
Izi zikutanthauza chiyani muzochita:
Kuchepetsa nkhawa m'mphepete mwa konkire
Ndioyenera-kumapeto-mapulogalamu apafupi
Kuchotsa kosavuta ndikuyikanso
Komabe, kukhala ndi mphamvu kumadalira kwambiri:
Kulondola kwa dzenje
Kachulukidwe konkriti
Kuyika torque
Momwe Nangula Amagwirira Ntchito (Ndi Chifukwa Chake Amanyamula Katundu Wochuluka)
Nangula amagwira ntchito mosiyanasiyana kutengera mtundu:
Nangula Zowonjezera
Wonjezerani kunja pansi pakumangitsa
Pangani kuthamanga kwa radial mkati mwa konkriti
Nangula Chemical
Gwirizanitsani ndi konkriti pogwiritsa ntchito zomatira
Kusamutsa katundu kudzera adhesion ndi kukangana
Zotsatira:
Nangula nthawi zambiri amapereka:
Kuchuluka kwa katundu
Kukhazikika kokhazikika pamapulogalamu amapangidwe
Koma nawonso akuyambitsa:
More unsembe masitepe
Kudalira kwakukulu pa ndondomeko yoyenera
Kuthekera Kwakatundu: Kumene Kusiyana Kweniyeni Kumawonekera
M'mapulogalamu enieni ambiri:
Nangula amaposa zomangira za konkire pakalemedwe kolemera
Zomangira konkriti ndizokwanirakukonza ntchito zopepuka kupita zapakati-
Chitsogozo chodziwika bwino (chothandiza, osati chongoyerekeza):
Ntchito yopepuka-(zotengera zingwe, mabulaketi) → zomangira ndizokwanira
Ntchito yapakati-yapakati (mafelemu, mbiri) → zimatengera kuyika
Zolemetsa zolemetsa → anangula amafunikira
Cholakwika chomwe ogula ambiri amapanga ndikusankha zomangira zopangira komwemalire oteteza katundu ndi otsika kwambiri.
Nthawi yoyika ndi Kuchita bwino
Ndemanga za makontrakitala:
Zomangira konkire zimachepetsa nthawi yoyika kwambiri
Palibe chifukwa chowonjezera kuwongolera kapena kuchiritsa nthawi
Kusintha kosavuta kumayitanidwe
Mumapulojekiti akuluakulu-:
Kupulumutsa nthawi kungakhale kwakukulu, makamaka mu:
Kuyika mobwerezabwereza
Machitidwe amkati
Zomanga zosakhalitsa
Nangula, kumbali ina:
Pamafunika masitepe ena
Kufuna apamwamba unsembe kulondola
Onjezani mtengo wantchito
Chiwopsezo Cholephera: Zomwe Zimasokonekera Patsamba
Zopangira Konkire Zimalephera Pamene:
Bowo loyendetsa ndege ndilozama kwambiri
Bowo la bowo ndilolakwika
Mphamvu za konkriti ndizosagwirizana
Kupitilira-makokedwe amawononga ulusi
Nangula Amalephera Pamene:
Kukulitsa sikukwanira
Kuyeretsa mabowo sikunyalanyazidwa (kofala kwambiri)
Nangula wa mankhwala samachiritsidwa bwino
Chidziwitso chofunikira:
Kulephera kwa screw nthawi zambiri kumachitikanthawi yomweyo,
Kulephera kwa nangula nthawi zambirikuchedwa- zomwe ndizowopsa kwambiri.
Kutalikirana Kwam'mphepete ndi Kukhudzidwa Kwazinthu
Zomangira konkriti zili ndi mwayi waukulu:
Kupanikizika kochepa kokulirapo
Chiwopsezo chochepa chosweka
Izi zimawapangitsa kukhala oyenera:
Kukonza m'mphepete
Zigawo zowonda za konkriti
Precast zinthu
Nangula, makamaka mitundu yokulitsa:
Ikhoza kuyambitsa kusweka
Pamafunika mtunda wocheperako
Mtengo Siwongogulitsa Mtengo
Ogula ambiri amayerekezera mtengo wa unit okha.
Koma mtengo weniweni umaphatikizapo:
Nthawi yoyika
Kuvala zida
Mtengo wolephera
Mtengo wokonzanso
Pochita:
Masikirini=otsika kutsogolo + kuyika mwachangu
Nangula=mtengo wapamwamba + chitetezo chokwera kwambiri
Kusankha kolondola kumadalirandalama zonse za polojekiti, osati mtengo wakuthupi wokha.
Nthawi Yomwe Mungagwiritsire Ntchito Zopangira Konkriti
Zomangira za konkriti ndi njira yabwinoko pamene:
Kukhazikitsa mwachangu ndikofunikira
Katundu ndi wapakatikati
Kukonzanso-kungafunike
Mtunda wam'mphepete ndiwochepa
Malo amkati kapena oyendetsedwa
Mapulogalamu odziwika:
Kukonza matabwa a simenti
Machitidwe amagetsi
Zopangira zitsulo zopepuka
Kuyika kwamkati
Pamene Anangula Ali Kusankha Bwino Kwambiri
Nangula ayenera kugwiritsidwa ntchito pamene:
Katundu-zofunika zonyamula ndizokwera kwambiri
Chitetezo ndichofunika kwambiri
Kukhazikika-kwanthawi yayitali ndikofunikira
Zigawo zakunja kapena zovuta zimakhudzidwa
Mapulogalamu odziwika:
Malumikizidwe zitsulo zomangamanga
Kuyika zida zolemera
Machitidwe oimitsidwa
Seismic kapena dynamic load zinthu
Njira Yosankhira (Yogwiritsidwa Ntchito ndi Ogula Odziwa)
M'malo mofunsa kuti:
"Ndi iti yabwino?"
Funsani:
Kodi chofunika ndi chiyani?
Kodi kukonzako ndi kokhazikika kapena kosinthika?
Kodi liwiro loyika ndi lofunika bwanji?
Kodi konkriti ndi chiyani?
Njirayi imapewa zolakwika zambiri zosankhidwa.
Mapeto
Zomangira konkire ndi anangula sizopikisana nawo - amagwira ntchito zosiyanasiyana.
Zomangira konkriti zimapereka liwiro komanso kusinthasintha.
Nangula amapereka mphamvu komanso kudalirika-kwanthawi yayitali.
Kusankha njira yoyenera yomangirira sikukhudza zokonda, koma zakufananiza magwiridwe antchito kuzinthu zenizeni zogwiritsira ntchito.
