Anchor screw
Maboti a nangula ndi ndodo zomangira zomwe zimagwiritsidwa ntchito kumangirira zida, ndi zina zambiri pamaziko a konkriti.Nthawi zambiri amagwiritsidwa ntchito pazomangamanga monga njanji, misewu yayikulu, mabizinesi amagetsi, mafakitale, migodi, milatho, ma cranes a nsanja, nyumba zazikulu zachitsulo ndi nyumba zazikulu.Ali ndi kukhazikika kwamphamvu.
Kufotokozera
Maboti a nangula nthawi zambiri amagwiritsa ntchito Q235 ndi Q345, zomwe ndi zozungulira.Zikuwoneka kuti sindinawone kugwiritsiridwa ntchito kwa ulusi, koma ngati mphamvu ikufuna, si lingaliro loipa.Rebar (Q345) ndi yamphamvu, ndipo ulusi wa mtedza siwophweka kukhala wozungulira.Kwa ma bolt ozungulira ozungulira, kuya kwa maliro nthawi zambiri kumakhala kuwirikiza ka 25 m'mimba mwake, ndiyeno mbedza ya madigiri 90 yokhala ndi kutalika pafupifupi 120mm imapangidwa.Ngati bwalo la bawuti ndi lalikulu (monga 45mm) ndipo kuya m'manda kuli kozama kwambiri, mbale yayikulu imatha kuwotcherera kumapeto kwa bawuti, ndiye kuti, mutu waukulu ungapangidwe (koma pali zofunika zina).Kuzama kwa maliro ndi mbedza zonse zimatsimikizira kukangana pakati pa bawuti ndi maziko, kuti asapangitse kuti bolt itulutsidwe ndikuwonongeka.Chifukwa chake, mphamvu yamakomedwe a bawuti ya nangula ndi mphamvu yamakomedwe ya chitsulo chozungulira chokha, ndipo kukula kwake ndi kofanana ndi gawo lachigawo chochulukitsidwa ndi mtengo wamapangidwe amphamvu yamakomedwe (140MPa), yomwe ndi mphamvu yololeka yonyamula. pa nthawi yopanga.Kuthekera kotheratu ndikochulutsa malo ake ophatikizika (omwe ayenera kukhala malo ogwira mtima pa ulusi) ndi mphamvu yachitsulo yachitsulo (Q235 mphamvu yachitsulo ndi 235MPa).Popeza mtengo wapangidwe uli kumbali yotetezeka, mphamvu yowonongeka panthawi yopangidwira imakhala yochepa kuposa mphamvu yomaliza.
Kuyika ndondomeko
Kuyika kwa ma bolt a nangula nthawi zambiri kumagawidwa m'njira zinayi.
1. Kuyima kwa mabawuti a nangula
Maboti a nangula ayenera kuyikidwa molunjika popanda kupendekera.
2. Kuyika mabawuti a nangula
Pakuyika ma bolts a nangula, ma grouting achiwiri a nangula wakufa nthawi zambiri amakumana nawo, ndiko kuti, pamene maziko atsanuliridwa, mabowo osungidwa azitsulo za nangula amasungidwa pasadakhale pa maziko, ndipo zomangira za nangula zimayikidwa. pa pamene zida zaikidwa.mabawuti, ndiyeno kutsanulira mabawuti nangula imfa ndi konkire kapena simenti matope.
3. Kuyika bawuti ya nangula - kumangitsa
4. Pangani zolemba zomangirira kuti mukhazikitse mabawuti a nangula ofanana
Panthawi yoyika ma bolts a nangula, zolemba zomanga zofananira ziyenera kupangidwa mwatsatanetsatane, ndipo mtundu ndi mafotokozedwe a zida za nangula ziyenera kuwonetsedwa mowona, kuti apereke chidziwitso chaukadaulo chothandizira kukonza ndikusintha mtsogolo.
Nthawi zambiri, zigawo zomwe zidayikidwapo zokhala ndi unsembe wapamwamba kwambiri ziyenera kupangidwa kukhala zotsekera pansi (mbale zachitsulo zomwe zidakulungidwa kale zomwe zidakhomeredwa m'mabowo ziyenera kuvala kaye, ndipo mtedza uyenera kuyikidwa kuti uzikanikizira pansi. Zigawo zomwe zidalowetsedwa kale ziyenera kumangirizidwa ku formwork ndikukhazikika.Kukula kwa ma bolts a phazi kumatha kutsimikizika.Ngati mukufuna kusunga zida, mutha kugwiritsanso ntchito zitsulo zowotcherera ndikuzikonza.Kuwotcherera kukamaliza, muyenera kuyang'ana miyeso ya geometric.Panthawiyi, kukhazikitsa bawuti kumapazi kwatha.
Standard
Maiko ali ndi machitidwe ndi miyezo yosiyana, monga British, malamulo, German, Australian standard, ndi American standard.
Zomwe Zimayambitsa Zidzimbiri
(1) Chifukwa cha sing’anga.Ngakhale kuti ma bolts ena samalumikizana mwachindunji ndi sing'anga, pazifukwa zosiyanasiyana, sing'anga yowononga imatha kufalikira kuzitsulo za nangula, zomwe zimapangitsa kuti zida za nangula ziwonongeke.
(2) Zifukwa za chilengedwe.Maboti achitsulo cha kaboni adzawononga malo amvula.
(3) Chifukwa cha zinthu za bawuti.M'mapangidwewo, ngakhale kuti ziboliboli za nangula zimasankhidwa motsatira malamulo, nthawi zambiri amangoganizira za mphamvu za ma bolts ndipo samaganizira kuti pansi pazikhalidwe zapadera, zida za nangula zidzawonongeka panthawi yogwiritsidwa ntchito, kotero kuti zipangizo zosagwirizana ndi dzimbiri monga zosapanga dzimbiri. zitsulo sizikugwiritsidwa ntchito.
