Zithunzi za Rebar
Rebar imadziwika kuti hot roll ribbed bar.Gawo lazitsulo wamba wamba wovinjidwa zitsulo zimakhala ndi zokolola zochepa za HRB ndi giredi.H, R ndi B ndi zilembo zoyamba za hot rolled, Ribbed and Bars motsatana.Rebar akhoza kugawidwa m'magulu atatu malinga ndi mphamvu: HRB300E, HRB400E, HRB500E, HRB600E, etc.
Mtundu wa ulusi wa rebar nthawi zambiri ndi 6-50mm.Nthawi zambiri timaphatikizapo zambiri ndi 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm ndi zina zotero.Kupatuka kovomerezeka kwa dziko : 6-12mm kupatuka mu ± 7%, 14-20mm kupatuka mu ± 5%, 22-50mm kupatuka mu ± 4%.Nthawi zambiri, kutalika kwa rebar ndi 9m ndi 12m, pomwe ulusi wautali wa 9m umagwiritsidwa ntchito kwambiri pomanga misewu wamba ndipo ulusi wautali wa 12m umagwiritsidwa ntchito kwambiri pomanga mlatho.

| Njira Yopanga | Rebar ndi chitsulo chachitsulo chokhala ndi nthiti, chomwe chimadziwikanso kuti nthiti zolimbitsa nthiti, nthawi zambiri zimakhala ndi nthiti zazitali za 2 ndi nthiti yopingasa yomwe imagawidwa molingana ndi kutalika kwake.Maonekedwe a nthiti yodutsa ndi mawonekedwe ozungulira, mawonekedwe a herringbone ndi mawonekedwe a crescent.Pankhani ya mamilimita awiri awiri mwadzina.The m'mimba mwake mwadzina wa ribbed reinforcement ndi wofanana ndi awiri mwadzina wa kulimbitsa wozungulira kuwala ndi chimodzimodzi mtanda gawo.M'mimba mwake mwadzina wa zitsulo kapamwamba ndi 8-50 mm, ndi awiri analimbikitsa ndi 8, 12, 16, 20, 25, 32 ndi 40 mm. Mipiringidzo nthiti makamaka amanyamula kupanikizika konkire.The ribbed zitsulo kapamwamba akhoza kupirira zochita za mphamvu kunja bwino chifukwa cha zotsatira za ribbed ndi konkire.Mipiringidzo yokhala ndi nthiti imagwiritsidwa ntchito kwambiri pazomangamanga zosiyanasiyana, makamaka zazikulu, zolemetsa, zopepuka zokhala ndi mipanda yopyapyala komanso zazitali. |
