Maboti a nangula (anangula) a kutsekereza kwakunja kwa matenthedwe amapangidwa ndi magawo okulitsa ndi manja okulitsa, kapena amangokhala ndi manja okulitsa.Iwo amadalira frictional mphamvu kapena mawotchi lotchinga zotsatira kwaiye ndi kukulitsa kulumikiza kutchinjiriza dongosolo ndi fasteners makina a m'munsi khoma.
Pakuyika kwa matabwa akunja otenthetsera kutentha, kuti dongosolo likhale lotetezeka, mitundu yosiyanasiyana ya nangula (nangula), mabatani achitsulo (kapena mabatani achitsulo) kapena zolumikizira zimagwiritsidwa ntchito molingana ndi zinthu kapena mtundu womaliza wamafuta. bolodi la insulation.njira zothandizira kulimbikitsa.
Bawuti ya nangula imagwiritsidwa ntchito kukonza zida zapadera zolumikizirana ndi mawotchi monga mawaya otentha, dip galvanized welded wire mesh, alkali-resistant glass fiber mesh kapena thermal insulation board, ndi lamba wodzipatula pakhoma.
Zitsulo za nangula ziyenera kupangidwa ndi magiredi achitsulo okhala ndi pulasitiki yabwinoko monga Q235 chitsulo ndi Q345 chitsulo, ndipo chitsulo champhamvu kwambiri sichiyenera kugwiritsidwa ntchito.Mtsuko wa nangula ndi gawo losavomerezeka, ndipo chifukwa cha kukula kwake kwakukulu, nthawi zambiri amapangidwa ndi zitsulo zozungulira zopanda makina monga C-grade bolt, ndipo samakonzedwa ndi lathe yapamwamba kwambiri.Maboti a nangula okhala ndi mapazi owonekera nthawi zambiri amagwiritsa ntchito mtedza wapawiri kuti apewe kumasuka.
Nangula ndi amitundu iyi:
(1) Bawuti yowonjezera nangula
Maboti owonjezera a nangula, omwe amatchedwa mabawuti okulitsa, amagwiritsa ntchito kusuntha kwa chulucho ndi pepala lokulitsa (kapena manja okulitsa) kulimbikitsa kukulitsa kwa pepala lokulitsa, kupanga mphamvu zowonjezera ndi zowonjezera ndi konkriti pakhoma la dzenje, ndikupanga kukoka kukana kudzera mukumeta ubweya wa ubweya.Chigawo chomwe chimazindikira kukhazikika kwa chidutswa cholumikizidwa.Maboti a nangula okulitsa amagawidwa kukhala mtundu wowongolera ma torque ndi mtundu wowongolera kutengera njira zosiyanasiyana zowongolera mphamvu pakukhazikitsa.Yoyamba imayendetsedwa ndi torque, ndipo yomalizayo imayendetsedwa ndi kusamuka.
(2) Nangula wa mtundu wa Reaming
Nangula wamtundu wa Reaming, womwe umatchedwa kuti reaming bolts kapena grooving bolts, akubwereranso ndikukonzanso konkire pansi pa dzenje lobowola, pogwiritsa ntchito makina olumikizirana pakati pa konkriti yonyamula pamwamba yomwe idapangidwa pambuyo pokonzanso ndi mutu wokulitsa wa bawuti ya nangula. ., chigawo chomwe chimazindikira kukhazikika kwa chidutswa cholumikizidwa.Maboti a nangula amagawika m'kukonzanso ndi kudzipangira okha molingana ndi njira zosiyanasiyana zopangiranso.Yoyamba ndi pre-grooving ndi reming ndi wapadera pobowola chida;bolt yomaliza ya nangula imabwera ndi chida, chomwe chimakhala chodzigudubuza ndikuyambiranso panthawi yoyika, ndipo grooving ndi kukhazikitsa zimamalizidwa nthawi imodzi.
(3) Maboti a nangula omangika
Zomangira za nangula zomangika, zomwe zimadziwikanso kuti ziboliboli zamankhwala, zomwe zimatchedwa ma bolts amankhwala kapena zomangira, zimapangidwa ndi zomatira zapadera zamankhwala (anchoring glue) kuti amamatire ndi kukonza zomangira ndi mipope yamkati mkati mwa mabowo obowola a magawo a konkire.Kumangirira ndi kutseka ntchito pakati pa zomatira ndi wononga ndi zomatira ndi khoma la dzenje la konkire kuti lizindikire chigawo chomwe chimamangiriridwa ku chidutswa cholumikizidwa.
(4) Kubzala mankhwala kwa tendons
Chomera chobzala mankhwala chimaphatikizapo zitsulo zopindika ndi ndodo zazitali, zomwe ndiukadaulo wolumikizana ndi nangula womwe umagwiritsidwa ntchito kwambiri m'mabwalo aukadaulo adziko langa.Nangula wa mipiringidzo yobzala mankhwala ndi yofanana ndi yomanga mabawuti a nangula, koma chifukwa kutalika kwa mipiringidzo yobzala mankhwala ndi zomangira zazitali sizochepa, ndizofanana ndi kukhazikika kwa mipiringidzo ya konkriti, ndi mawonekedwe owonongeka. ndi yosavuta kuwongolera, ndipo nthawi zambiri imatha kuwongoleredwa ngati kuwonongeka kwa mipiringidzo ya nangula.Chifukwa chake, ndiyoyenera kulumikizana ndi ma anchorage a mamembala omangika kapena osakhazikika omwe mphamvu zawo zokhazikika komanso zolimba za seismic ndizochepera kapena zofanana ndi 8.
(5) Zomangira konkriti
Mapangidwe ndi makina okhazikika a zomangira za konkriti ndizofanana ndi zomangira zamatabwa.Njira yapadera imagwiritsidwa ntchito pogubuduza ndi kuzimitsa wononga zolimba ndi zakuthwa za ulusi wa mpeni.Pakuyika, dzenje lolunjika lokhala ndi mainchesi ang'onoang'ono limabowoleredwa kale, ndiyeno phula limakulungidwa, pogwiritsa ntchito ulusi ndi dzenje.Kuchita kwa occlusal pakati pa khoma konkire kumatulutsa mphamvu yokoka ndikuzindikira chigawo chomwe chimamangiriridwa ku mbali zogwirizanitsa.
(6) Kuombera misomali
Msomali wowombera ndi mtundu wa misomali yachitsulo yolimba kwambiri, kuphatikizapo zomangira, zomwe zimayendetsedwa ndi mfuti, mu konkire, ndikugwiritsa ntchito kutentha kwake (900 ° C) kupanga misomali yachitsulo ndi konkire yophatikizidwa chifukwa cha kusakanikirana kwa mankhwala ndi kugwedeza.Zindikirani anangula wa magawo ogwirizana.
