Rebar - ibikoresho by'ingenzi mu bwubatsi

I. Ibisobanuro by'umurambararo (Icyiciro cy'ingenzi cyo gukoresha) Ibisobanuro by'umurambararo wa HRB400E rebar bigomba kubahiriza neza "Ibiti by'icyuma bishyushye bifite umugozi bya sima ishyigikiwe" (GB/T 1499.2-2018). Ingano y'umurambararo ni 6mm-50mm, bikubiyemo ibintu byinshi bibangamira mu buhanga. Ingano zitandukanye zihuye n'ibisabwa bitandukanye byo gukoreshwa, nk'ibi bikurikira: Ingano nto (6mm-12mm): Ikoreshwa cyane cyane ku bice bito, ibiti bigabanya umugozi, n'ibiti bikwirakwiza umugozi, nk'ibiti bigabanya umugozi, ibiti bifunga umugozi, ibiti bifunga umugozi, n'ibindi. Ibisobanuro bikunze gukoreshwa ni 6mm, 8mm, 10mm, na 12mm; Ingano iringaniye (14mm-25mm): Ikoreshwa cyane, ikwiriye ibice bigabanya umuvuduko nk'imiringa y'inkingi, inkingi z'inkingi, impande z'inkuta, n'imigozi y'ibirundo. Ibisobanuro bikuru ni 14mm, 16mm, 18mm, 20mm, 22mm, na 25mm; Ubugari bunini (28mm-50mm): Ikoreshwa cyane mu nyubako nini, ibice biremereye cyangwa ibice biremereye, nk'inkingi nini z'inkingi, imitako y'ibiraro, amasanduku y'ibyuma by'ifatizo, n'ibikoresho binini byo gushimangira ishingiro. Ibipimo bisanzwe ni 28mm, 32mm, 36mm, 40mm na 50mm. II. Ingano zo hanze n'ibipimo by'imbavu (Ibisabwa n'itegeko)
Rebar ya HRB400E ifite igice cy’uruziga gifite imbavu ku burebure bwacyo. Imbavu zigabanyijemo imbavu z’inyongera (zijyanye n’umurongo w’inyuma) n’imbavu z’inyongera (ku nguni runaka ku murongo w’inyuma). Ibipimo bigomba kuzuza ibi bikurikira kugira ngo harebwe ko ifatana n’imikorere y’inkingi hamwe na beto:
Igishushanyo mbonera cy'imbavu zihinduranya:
Inguni: Inguni β iri hagati y'urubavu runyuranamo n'umurongo w'inyuma igomba kuba hagati ya 45° na 60°. Iyo umurambararo wa rebar d ≤ 12mm, inguni ishobora kwaguka neza kugeza kuri 30°.
Intera: Intera iri hagati y'imbavu l igomba guhindurwa kugira ngo ijyane n'umurambararo. Urugero, l ≤ 12mm iyo d = 6mm, l ≤ 20mm iyo d = 25mm, na l ≤ 25mm iyo d = 50mm. Intera iri hagati y'imbavu l igomba kurenga ± 10%.
Uburebure: Uburebure bw'imbavu zinyura hejuru h bugomba kuzuza ingufu n'ibisabwa mu gufatanya. Urugero, h ≥ 0.8mm iyo d = 10mm, na h ≥ 0.8mm iyo d = 20mm. Iyo h ≥ 1.5mm, na d = 40mm, h ≥ 2.4mm, kandi uburebure nyabwo bupimwe ntibugomba kuba munsi ya 90% by'agaciro gasanzwe. Igishushanyo cy'imbavu zinyura hejuru: Ingano: Buri mbavu zinyura hejuru zisaba imbavu 2 zinyura hejuru zikwirakwijwe mu buryo bungana. Ubugari b bw'imbavu zinyura hejuru bugomba guhuza n'umurambararo, urugero, b = 2.0mm iyo d = 16mm, b = 3.0mm iyo d = 32mm; Uburebure: Imbavu zinyura hejuru zigomba gukora uburebure bwose bw'imbavu zinyura hejuru nta cyuho cyangwa ibibangamira, kandi hejuru y'imbavu zinyura hejuru zigomba guhinduka neza kugera hejuru y'imbavu zinyura hejuru kugira ngo hirindwe ko impande zibyimbye zitera stress. Guhindagurika kw'igice: Guhindagurika kw'umurambararo nyawo kw'icyuma gifunga bigomba kuba muri ± 0.4mm (urugero, kuri icyuma gifunga gifite umurambararo wa mm 20, umurambararo nyawo wapimwe ugomba kuba hagati ya mm 19.6 na mm 20.4); Guhindagurika kw'igice ntibigomba kurenga ± 2%, kandi uburebure bw'urukiramende (itandukaniro riri hagati y'umurambararo ntarengwa n'umurambararo muto w'igice) bugomba kuba ≤0.4mm kugira ngo habeho imiterere isanzwe y'igice n'ikwirakwizwa ry'imitsi rimwe.
