Tsananguro yeSimbi yeRebar Grades, Saizi neMaitiro eSimbi

Gwaro Rinoshanda reVashandi veKutenga Simbi neVashandi veKuvaka

Hunhu hwesimbi yekugadzikaine simba guru pakuvaka zvivakwa zvekongiri yakasimbiswa, kusanganisira kuchengetedzeka kwezvivakwa, kugona kuvaka, uye mitengo yezvinhu.

Kune vanotenga simbi, makondirakiti, uye mainjiniya, kunzwisisasimbi yekabhoni rebarmagiredhi, zviyero zvehukuru, uye nzira dzekurongedza pasi pemitemo yakasiyana yekutenga nekushandisa mapurojekiti pamusika nepasi rose zvakakosha.

Gwaro iri rine chinangwa chekupa pfupiso uye hunyanzvi hwemitemo yepasi rose ye rebar, kunyanya inosanganisiraMitemo yeChinese (GB), European (EN), uye American (ASTM).

Magiredhi eRebar Anokanganisa Simba reGoho uye Standard

Kune mutsauko mugiredhi resimbi yekusimbisa zvichienderana nesimba diki rekugadzira uye zita regiredhi rinoenderana nezvinodiwa uye mutsauko waro kubva kune imwe nzvimbo kuenda kune imwe.

Muganho weChina –GB 50010 /GB1499.2
Mhando dzezvishandiso zvehot-rolled ribbed rebar dzinoshandiswa zvakanyanya muChina ndeidzi:
HRB335 Simbi Rebar
Simba shoma regoho: 335 MPa
Kwebasa renguva dzose rekongiri yakasimbiswa.
HRB400Sbhaa resimbi
Simba shoma regoho: 400 MPa
Mashandisirwo edzimba, mabhizinesi uye zvivakwa.
HRB500 Steel Rebar
Simba shoma regoho: 500 MPa
Yakakodzera zvivakwa zvinorema, zvikuru uye zvirefu
Tsanangudzo yeGiredhi:
HRB = Bhawa Rakaputirwa Rinopisa
Nhamba iyi inoratidza simba reminimum yield (MPa).

Muyero weEurope – EN 10080 (B500 Series)
Mitemo yeEuropean rebar inotarisa zvakanyanya pakushanda zvakanaka kwesimbi izvo zvakakosha pakushanda kwepasi rose.
B500A – 500 MPa, ductility yakaderera
B500B – 500 MPa, ductility yepakati
B500C – 500 MPa, ductility (inoshandiswa mukuvaka kwepasi)
Pavanhu ivavo, B500C ndiyo inonyanya kushandiswa.

Muyero weUSA - ASTM A615 / ASTM A706
Simba reRebar rinotsanangurwa zvakasiyana mumusika weUS (uko ksi inoshandiswa pachinzvimbo cheMPa):
Giredhi 40 – 40 ksi ≈ 275 MPa
Giredhi 60 - 60 ksi ≈ 420 MPa (inonyanya kushandiswa)
Giredhi 75 – 75 ksi ≈ 520 MPa
Cherechedza:
ASTM A615: chiyero chekusimbisa simbi yekabhoni
ASTM A706: kuchinjika kwakawedzerwa uye kugona kuchinjika uye inowanzoshandiswa pakushandisa kudengenyeka kwenyika

Saizi dzeRebar dzakajairika uye Dhayamita

Mipimo yehukuru hwe rebar inosiyana munzvimbo dzakasiyana uye inofanira kuenzaniswa zvakanaka panguva yekutenga.

Dhayamita Dzakajairika dzeRebar muChina (mm)
6, 8, 10, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40
Dhayamita diki (≤12 mm): matombo esimbi, masitirupu, zvivakwa zvemwenje
Dhayamita hombe (≥16 mm): matanda, mbiru, nheyo, mabhiriji
Madhayamita Akajairika eRebar muEurope (mm)
6, 8, 10, 12, 16, 20, 25, 32, 40

Mapurojekiti ekuEurope anowanzo shandisa dhayamita yakajairika, zvichivandudza kushanda zvakanaka kwekuvaka.

Chati yeSaizi yeRebar yeUS (# Sisitimu yeBar)
Rebar yekuUS inozivikanwa nenhamba dzebha, kwete nedhayamita dzakananga:
#3 → 9.5 mm
#4 → 12.7 mm
#5 → 15.9 mm
#6 → 19.1 mm
#7 → 22.2 mm
#8 → 25.4 mm
#9 → 28.7 mm
#10 → 32.3 mm

Zano rekutenga:
Gara uchichinja saizi dzebha # kuita metric diameters paunenge uchitsvaga rebar pasi rese kudzivirira kusawirirana kwehuremu uye kushivirira.

Kureba, Kurongedza, uye Kutumirwa kweRebar

Hurefu Hwakajairika
9 m
12 m
Kucheka-cheka kwenguva refu kunowanikwa kana uchida.

Rudzi rweKurongedza
Mapaketi akareruka - emabhawa akakura
Tied rebar - ndiyo nzira inonyanya kufarirwa yekutakura zvinhu zvakawanda mumidziyo yemumagaba
Rebar yakakochekerwa (dhayamita diki - 6-10 mm kana yakafanana, yakakodzera kugadziriswa otomatiki)

Mazano ekusarudza Rebar Yakanakisisa yePurojekiti Yako

Kubva pamaonero ekutenga nekugadzira zvinhu:

Tarisa makodhi ekugadzira uye zvinodiwa zvekutevedzera mitemo yemunharaunda usati wasarudza mamakisi.
Kune zvivakwa zvinokanganiswa nekudengenyeka kwenyika kana kuti zvine kuchengetedzwa kwakanyanya, funga nezvekushanda zvakanaka kwete kusimba.
Tarisa kuti zvinoenderana here nezvinodiwa/hurongwa hwehukuru hwebhawa/kushivirira urefu hweprojekiti yako yekuburitsa kunze kwenyika.

Kureba kwakakodzera uye kurongedza kwakakodzera zvinogonawo kudzivirira marara uye kuderedza mari yekubata.

Kunyangwe zvakadarosimbi yekugadzikaimhando yekuvaka yakajairika, magiredhi akasiyana, masisitimu ehukuru, uye mwero wedunhu zvinogona kukanganisa zvakanyanya mutengo wepurojekiti, kutevedzera mitemo, uye mashandiro echivakwa.
Kune vanotenga simbi nenyanzvi dzekuvaka, kunzwisisa misiyano iyi kunoreva magadzirirwo akachengeteka, kutenga zviri nyore, uye kuwana zvinhu zvine mutengo uri nani.
