classification

Iyo inopisa-yakakungurutswa ribbed simbi simbi yakakamurwa kuita mamakisi matatu: HRB335 (yekare giredhi 20MnSi), giredhi rechitatu HRB400 (yekare giredhi 20MnSiV, 20MnSiNb, 20Mnti), uye giredhi rechina HRB500.
Pane nzira mbiri dzinowanzo shandiswa dzekuisa simbi yekusimbisa mabara:imwe ndeyekuronga maererano nemaumbirwo ejometri, uye imwe ndeyekuronga kana kurongedza zvichienderana nechikamu-chikamu chechimiro chemabhawa anochinjika uye kuparadzaniswa kwembariro. Type II.Iyi kupatsanurwa kunonyanya kuratidza clamping kuita kwekusimbisa.

Yechipiri inoenderana nemaitiro ekuita (giredhi), senge yazvino yekumisikidzwa mwero munyika yangu, rebar iri (GB1499.2-2007) waya iri 1499.1-2008), uye rebar yakakamurwa kuita 3 zvichienderana negiredhi resimba (goho poindi / kusimba simba). Grade; muJapan Industrial Standard (JI SG3112), mbariro dzesimbi dzakakamurwa kuita zvikamu zvishanu maererano nehupamhi hwazvo; muBritish Standard (BS4461), mamakisi akati wandei esimbi bar performance test anotsanangurwa zvakare. Pamusoro pezvo, mbariro dzesimbi dzinogonawo kuverengerwa nekushandiswa, senge dzakajairwa simbi mbariro dzekongiri yakasimbiswa uye nekushisa-yakagadziriswa simbi simbi ye prestressed reinforced kongiri.

chimiro

1) Nominal dhayamita siyana uye yakakurudzirwa dhayamita
Iyo dhayamita yematanho esimbi inotangira pa6 kusvika pa50mm, uye chiyero chinokurudzirwa mazita emadhayamita emasimbi 6, 8, 10, 12, 14, 16, 20, 25, 32, 40, uye 50mm.
2) Kutsauka kunobvumirwa kwechimiro chepamusoro uye saizi yembabvu simbi bar
Iyo misimboti yekugadzira ye ribbed simbi mabara anofanirwa kuita zvinotevera zvinodiwa:
Iyo kona β pakati pembabvu inochinjika uye simbi bar axis haifanirwe kunge iri pasi pe45 madhigirii. Kana iyo kona inosanganisirwa isiri yakakura kupfuura 70 madhigirii, kutungamira kwemazariro akachinjika pamativi ese esimbi simbi inofanira kupesana;
Iyo yezita spacing l yemabhawa anochinjika haifanire kunge yakakura kudarika 0.7 times the nominal diameter of the bars;
Iko kona α pakati pedivi rembabvu yakachinjika uye pamusoro pesimbi yesimbi haifaniri kunge iri pasi pe45 degrees;
Huwandu hwemagapu (kusanganisira hupamhi hwembabvu refu) pamigumo yembabvu dzakachinjika pamativi ese ari padyo nesimbi yesimbi haifanire kunge yakakura kupfuura 20% yezita rekutenderera kwesimbi bar;
Kana iyo dhayamita yezita resimbi yesimbi isingasviki 12mm, nzvimbo yembabvu yehama haifanire kunge iri pasi pe0.055; apo dhayamita yezita iri 14mm uye 16mm, nzvimbo yembabvu haifanirwe kunge iri pasi pe0.060; kana iyo dhayamita yezita yakakura kupfuura 16mm, nzvimbo yembabvu yehama haifanire kunge iri pasi pe0.065. Ona Appendikisi C yekuverenga nzvimbo yembabvu.
Mbabvu simbi mbariro kazhinji ane longitudinal mbariro, uye kune zvakare ayo asina longitudinal mbariro;

3) Kureba uye kutendeseka kutsauka
Poshi. urefu
Simbi dzesimbi dzinowanzounzwa muhurefu hwakatarwa, uye hurefu hwekutakura hunofanirwa kuratidzwa muchibvumirano;
Mazariro esimbi anogona kuendeswa mumipumburu, mupumburu wega wega unofanirwa kuva simbi imwe chete, uye 5% yenhamba yemapumburu pabatch (pasi pemapumburu maviri ari maviri rolls) ane maviri simbi mbariro. Iyo disk huremu uye dhisiki dhayamita inotemerwa kuburikidza nekutaurirana pakati pemutengesi nemutengi.
b. Kureba kushivirira
Kana kureba kwakagadziriswa kuchiendeswa, kutsauka kunobvumirwa kwehurefu hwesimbi yesimbi hakusi kupfuura ± 25mm;
Kana hurefu hudiki hunodiwa, kutsauka kuri +50mm;
Kana kureba kwepamusoro kunodiwa, kutsauka ndiko -50mm.
c. Curvature uye magumo
Kupera kwesimbi yesimbi kunofanira kutemwa zvakananga, uye deformation yemunharaunda haizokanganisa kushandiswa
