Ukobvu: 6-40mm
Maitiro: Kupisa kwakatenderedzwa, Ribbed, Rounded, Alloy
Rebar izita rakajairika kune inopisa-yakakungurutswa ribbed simbi simbi.Iyo giredhi yeyakajairwa inopisa-yakatenderedzwa simbi bar ine HRB uye yakaderera goho poindi yegiredhi.H, R, uye B vane Hotrolled, Ribbed, uye Bhara zvakateerana.
Pane nzira mbiri dzinowanzo shandiswa dzekuisa rebar: imwe ndeyekuisa muchikamu nechimiro chejometri, uye kuisa kana kutaipa zvinoenderana neyakachinjika-chikamu chimiro chembabvu yakachinjika uye kuparadzaniswa kwembabvu.Type II.Uku kusarudzika kunonyanya kuratidza kubata kunobata kweiyo rebar.Yechipiri yakavakirwa padanho rekuita (giredhi), senge nyika yangu yazvino kuita chiyero, rebar iri (GB1499.2-2007) waya iri 1499.1-2008), zvinoenderana nedanho resimba (goho poindi / simba rekusimba) Iyo rebar iri yakakamurwa kuita 3 mamakisi;muJapan Industrial Standard (JI SG3112), iyo rebar yakakamurwa kuita mhando 5 zvichienderana nekuita kwakazara;muBritish Standard (BS4461), mamakisi akati wandei ebvunzo rebar performance test anotsanangurwa zvakare.Pamusoro pezvo, mabhara anogonawo kuverengerwa zvinoenderana nekushandiswa kwawo, senge akajairwa simbi mbariro dzekongiri yakasimbiswa uye nekushisa-kupisa simbi simbi ye prestressed yakasimbiswa kongiri.
Dimensions
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 simbi
Magadzirirwo emisimboti yembabvu dzakachinjika dzembabvu simbi simbi dzinosangana nezvinodiwa zvinotevera:
Iyo kona β pakati pembabvu inochinjika uye axis yesimbi bar haifanirwe kunge iri pasi pe45 madhigirii.Kana iyo kona inosanganisirwa isiri yakakura kupfuura 70 madhigirii, kutungamira kwembabvu dzakachinjika kumativi akatarisana esimbi simbi inofanira kupesana;
Iyo yezita spacing l yembabvu dzakachinjika haifanire kunge yakakura kudarika 0.7 nguva yezita redhayamita yesimbi simbi;
Iko kona α pakati pedivi rembabvu yakachinjika uye pamusoro pesimbi yesimbi haifaniri kunge iri pasi pe45 degrees;
Huwandu hwemagapu (kusanganisira hupamhi hwembabvu refu) pakati pemigumo yembabvu dzakachinjika pamativi maviri ari padyo nesimbi yesimbi haifanire kunge yakakura kupfuura 20% yezita rekutenderera resimbi 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.Tarisa kuAppendix C kuti uverenge nzvimbo yembabvu.
Ribbed simbi mbabvu kazhinji ane longitudinal mbabvu, asiwo asina longitudinal mbabvu;
3) Kureba uye kutendeseka kutsauka
a.Urefu
Simbi dzesimbi dzinowanzounzwa muhurefu hwakatarwa, uye hurefu hwekutakura hunofanirwa kuratidzwa muchibvumirano;
Mabhawa ekusimbisa anogona kuendeswa mumakoiri, uye reel yega yega inofanirwa kunge iri rebar imwe, ichibvumira 5% yehuwandu hwemareel mubatch yega yega (maviri reels kana ari pasi pemaviri) ane maviri rebar.Iyo disk huremu uye dhisiki dhayamita inotemerwa kuburikidza nekutaurirana pakati pemutengesi nemutengi.
b, kureba kushivirira
Kutsauka kunobvumirwa kwehurefu hwesimbi yesimbi kana ichiendeswa kune yakagadziriswa urefu haifaniri kudarika ± 25mm;
Kana hurefu hudiki hunodiwa, kutsauka kwayo ndeye +50mm;
Kana kureba kwepamusoro kunodiwa, kutsauka ndiko -50mm.
c, curvature uye magumo
Kupera kwesimbi yesimbi kunofanirwa kuveurwa zvakananga, uye deformation yenzvimbo haifanire kukanganisa kushandiswa
