Kodi mukudziwa kusiyanitsa ukadaulo wobzala, mankhwala a anchor bolt, zokulitsa ndi zomangira?

Ukadaulo wa posch womwe tsopano ukugwiritsidwa ntchito pamakampani olimbikitsira njira zowonjezera, kutumiza ukadaulo wonse kwathunthu kumagawika: chitsulo chobzala mankhwala, zomangira zomangirira, zomangira nangula zokulirapo.
Chemical kubzala zitsulo bala
Chitsulo chobzala zitsulo, chotchedwa chitsulo chachitsulo, ndi mtundu waukadaulo wolumikizira womwe umagwiritsidwa ntchito kwambiri ku China. Ndi mtundu wa chinthu chomwe chimagwiritsa ntchito zomatira zamagetsi - zomatira zomata kuti akonze chitsulo chosungunuka ndikulumikiza mu dzenje lobowola gawo lapansi la konkriti. Kudzera mwa kulumikizana ndi kutseka ntchito, imatha kuzindikira kukhazikika kwa magawo olumikizidwa.

Mfundo yolimbirana ndi bala yazitsulo ndi yofanana ndi zomata zomangirira, koma kutalika kwazitsulo zazitsulo ndi zomangira sizingokhala zochepa, zomwe zikufanana ndi kuponyera konkriti kolimba kolimba. Njira yolephera ndiyosavuta kuyang'anira, ndipo nthawi zambiri imatha kuwongoleredwa ngati kulephera kwa bala yazitsulo. Chifukwa chake, ndiyabwino kulumikizana kwa mamembala am'magulu osakhazikika omwe sali olimba mwamphamvu ≤ madigiri a 8. Ponena za kulumikizana kwa anchorage kwa mamembala omwe ali ndi kutopa, tiyenera kugwiritsa ntchito moyenera.

Zomatira nangula bawuti
Zomatira nangula bawuti, amatchedwanso mankhwala zomatira bawuti, kapena zomatira bawuti mwachidule, ndi mtundu wa chinthu chomwe chimagwiritsa ntchito mankhwala omatira apadera (okutira guluu) kukonza mabotolo ndi mapaipi amkati omwe amamangiriridwa mu dzenje lobowolera gawo la konkriti, ndipo amazindikira kumangirira mbali zolumikizidwa kudzera pakulumikizana ndi kusoka pakati pa zomatira ndi zomangira, komanso pakati pa zomatira ndi khoma loboola la konkriti.
Pakali pano, msika atathana chomangira mtundu nangula akapichi amakhala ambiri wakuda ndi waufupi, kuya kwa nangula ndi kosazama, kusinthasintha kwa ming'alu zakuthupi ndizosauka, ndipo mphamvu yobereka ndiyotsika kwambiri, yomwe siyoyenera kulumikizana ndi positi mamembala omwe ali ndi mavuto, kukameta ubweya m'mphepete, kupsyinjika kwakumetana kophatikizana komanso mamembala ena aukadaulo wamoyo; Kuphatikiza pa zomangira zamtundu wa nangula zomwe zimagwiritsidwa ntchito popanga konkriti, zomangira zonse zomwe sizimangiriridwa sizoyenera kupanga konkriti.

Mawotchi nangula bawuti
Bokosi la nangula lokhala ndi katundu wonyamula katundu liyenera kukhala bwalo lamatabwa lakumbuyo lomwe limagwira ntchito potseka. Mtundu uwu wa nangula umatha kugawidwa kukhala wokhazika nangula, ndikufutukula zomangirira ndikumangirira kufa ndikukulitsa nangula malinga ndikumanga kwake kosiyanasiyana. Bokosi lazomangirira lonyamula katundu liyenera kukhala lapadera lokhazikika pakachitsulo chomangirira. Zomangira zokha sizikhala za dongosolo la anchor, kotero siziyenera kupangidwa ndikuwerengedwa molingana ndi nangula.

Kukula kwa bolt
Kukula kwa bolt. Bokosi lokulitsa limakulungidwa ndi chubu cha mphete. Pali mpata pa chubu cha mphete. Ikagwiritsidwa ntchito, pangani khoma. Ikani zowonjezera zowonjezera mdzenje. Mukamangitsa bawuti, mbiya yaming'onoyi imafinyidwa ndikutambasulidwa. Mwanjira imeneyi, bolt imalumikizidwa mdzenje ndikusewera.

Kusiyana pakati pawo
1, Kupanikizika mfundo
(1) Chitsulo chophatikizira chachitsulo chiyenera kukhala chazitsulo chazitsulo zonse kapena chitsulo cholumikizira nthiti, ndipo mphamvu yomata imagwiritsidwa ntchito kuzindikira kupsinjika ndikupanga chikhazikitso;
(2) Bokosi limaloledwa kukhala ndi zomangira zosalala, zomwe zimakakamizidwa ndi makina otsekemera;
(3) Kukulitsa nangula kumangirira kumadalira mkangano pakati pa kutsegula kwa chitoliro ndi konkriti kukana kukoka. Mphamvu yokoka imakhala ndi ubale wabwino ndi ukadaulo wa zomangamanga ndi zinthu zaumunthu, chifukwa chake ndizosachita kuyesa kwamakokedwe.
2, Anchorage kuya
(1) Kuzama kwazitsulo zazitsulo zophatikizidwa kumakhala kwakukulu kuposa 15d pambuyo powerengedwa ndi chilinganizo chowerengera;
(2) The anchorage kuya kwa nangula bawuti ayenera kukhala ochepera 10d;
(3) Kuzama kwa bawuti wokulitsa kumatsimikizika molingana ndi mphamvu za konkriti ndikukula kwa bawuti.
3 、 Mawonekedwe a chiwonongeko
Mwambiri, pali mtundu umodzi wokha wa kulimbitsa zolimbitsa. Njira zololeza zovomerezeka za anchor bolt ndikukula kwa bolt ndizitsulo zolephera zazitsulo komanso kulephera kwa konkriti.
Makatani owonjezera ndi ma bolts amankhwala ndi ma bolts okhazikika. Nthawi zina, zida zokulitsira kapena nangula zamankhwala zimafunika chifukwa sizinaphatikizidwe kale. Koma izi ziyenera kupewedwa pakupanga. Chifukwa akapichi a nangula akuyenera kuphatikizidwa. Mwachitsanzo, nangula akapichi pamunsi. Chifukwa njira yokhayi titha kuonetsetsa kumamatira bwino komanso kupsinjika. Ndipo pambuyo pobowola, nthawi zambiri imayambitsa kuwonongeka kwa chitsulo chopanikizika mu konkriti ndi konkriti yomwe.
Gwiritsani ntchito mawonekedwe
Mwatsatanetsatane wa konkriti, zida zomwe zidapangidwa mu konkriti zimatchedwa magawo ophatikizidwa. Malinga ndi Unduna wa zolemba, zomanga zokulitsa sizigwiritsidwa ntchito pamakoma amatchinjiro. Mwambiri, sikuletsedwa konse kugwiritsa ntchito bolt yowonjezera yomanga yatsopano, ndipo iyenera kuphatikizidwa.
M'nkhani 4.1.1 ya jgj145 yaukadaulo waukadaulo wa zomangira za konkriti, zomatira nangula bawuti akuti: "zomatira nangula bawuti imagwiritsidwa ntchito kwambiri m'maiko akunja, koma kafukufuku waposachedwa akuwonetsa kuti magwiridwe ake ndi osavomerezeka, makamaka gawo losweka la konkriti, njira yowerengera siyakhwima mokwanira, ndipo njira yake yolephera ndiyovuta kuiwongolera.

Mukamagwiritsa ntchito mabatani owonjezera, kupanikizika kumachitika pakonkriti, zomwe zimawonjezera mwayi wakulephera ndikupangitsa kuti mawonekedwe asakhale otetezeka. Chifukwa chake, ma bolt owonjezera sangathe kugwiritsidwa ntchito pakonkriti wosweka. Chifukwa chake tsopano zaletsedwa pakupanga makatani. Ngati mukufuna kuwunikanso zojambulazo, zokulitsa sizingadutse.
Pakadali pano, kubzala ukadaulo wazitsulo ndi ukadaulo wowonjezera. Chifukwa cha ukadaulo wake wokhwima, wawoneka m'mapulogalamu ambiri atsopano komanso othandizira.
