Magiredi a Rebar a Chitsulo, Kukula ndi Miyezo Yofotokozedwa

Buku Lothandiza kwa Akatswiri Ogula ndi Kumanga Zitsulo

Ubwino wachogwirira chachitsulozimakhudza kwambiri nyumba zomangira konkire yolimbikitsidwa, kuphatikizapo chitetezo cha nyumba, kuthekera komanga, komanso mtengo wa zinthu.

Kwa ogula zitsulo, makontrakitala, ndi mainjiniya, kumvetsetsachogwirira chachitsulo cha kabonimagiredi, miyezo ya kukula, ndi njira zopakira pansi pa miyezo yosiyanasiyana yogulira ndi kugwiritsa ntchito mapulojekiti pamsika ndi padziko lonse lapansi ndizofunikira kwambiri.

Chikalatachi cholinga chake ndi kupereka chithunzithunzi chachidule komanso chaukadaulo cha miyezo yapadziko lonse lapansi ya rebar, makamaka yokhudzaMiyezo ya Chitchaina (GB), Chizungu (EN), ndi Chimereka (ASTM).

Magiredi a Rebar Okhudza Mphamvu ya Zokolola ndi Muyezo

Pali kusiyana kwa kalasi ya chitsulo cholimbitsa kutengera mphamvu yocheperako ya zokolola ndipo dzina la kalasi lidzadalira miyezo yoyenera komanso kusiyana kwake kuchokera kudera lina kupita ku lina.

Muyezo wa China –GB 50010 /GB1499.2
Mitundu ya rebar yopangidwa ndi ribbed ribbed yomwe imagwiritsidwa ntchito kwambiri ku China ndi iyi:
HRB335 Chitsulo Chokhazikika
Mphamvu yocheperako yopezera: 335 MPa
Kwa ntchito yanthawi zonse yolimbitsa konkire.
HRB400SRebar yachitsulo
Mphamvu yocheperako yopezera: 400 MPa
Ntchito zogwirira ntchito m'nyumba, m'mabizinesi ndi m'zomangamanga.
HRB500 Chitsulo Chokhazikika
Mphamvu yocheperako yopezera: 500 MPa
Yoyenera nyumba zokhala ndi katundu wambiri, zazikulu komanso zazitali
Tanthauzo la Giredi:
HRB = Mzere Wotentha Wozungulira Ribbed
Nambalayo imasonyeza mphamvu yocheperako ya yield (MPa).

Muyezo wa ku Ulaya – EN 10080 (Mndandanda wa B500)
Miyezo ya rebar ya ku Europe imayang'ana kwambiri pa ductility yomwe ndi yofunika kwambiri pakugwira ntchito kwa zivomerezi.
B500A – 500 MPa, mphamvu yotsika
B500B – 500 MPa, mphamvu yapakati yogwirira ntchito
B500C – 500 MPa, mphamvu yodumphadumpha (yogwiritsidwa ntchito popanga zivomerezi)
Mwa iwo, B500C ndiyo yodziwika kwambiri.

Muyezo wa USA – ASTM A615 / ASTM A706
Mphamvu za rebar zimafotokozedwa mosiyana pamsika waku US (komwe ksi imagwiritsidwa ntchito m'malo mwa MPa):
Kalasi 40 – 40 ksi ≈ 275 MPa
Giredi 60 - 60 ksi ≈ 420 MPa (yogwiritsidwa ntchito kwambiri)
Kalasi 75 - 75 ksi ≈ 520 MPa
Zindikirani:
ASTM A615: muyezo wolimbitsa chitsulo cha kaboni
ASTM A706: kusinthasintha kwabwino kwa kusongoka ndi kusinthasintha ndipo imagwiritsidwa ntchito kwambiri pakugwiritsa ntchito zivomerezi

Kukula ndi Ma Diameter Okhazikika a Rebar

Miyezo ya kukula kwa mipiringidzo imasiyana m'madera osiyanasiyana ndipo iyenera kugwirizanitsidwa mosamala panthawi yogula.

Ma diameter a Common Rebar ku China (mm)
6, 8, 10, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40
Ma diameter ang'onoang'ono (≤12 mm): slabs, stirrups, ndi zomangira zowala
Ma diameter akuluakulu (≥16 mm): matabwa, zipilala, maziko, milatho
Ma diameter a Common Rebar ku Europe (mm)
6, 8, 10, 12, 16, 20, 25, 32, 40

Mapulojekiti aku Europe nthawi zambiri amagwiritsa ntchito mtunda wofanana kwambiri, zomwe zimapangitsa kuti ntchito yomanga ikhale yogwira mtima.

Tchati cha Kukula kwa Rebar ku US (# Dongosolo la Bar)
Rebar ya ku US imadziwika ndi manambala a bar, osati ma diameter olunjika:
#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

Malangizo ogulira:
Nthawi zonse sinthani kukula kwa mipiringidzo # kukhala ma metric diameters mukamagwiritsa ntchito rebar padziko lonse lapansi kuti mupewe kusiyana kwa kulemera ndi kulekerera.

Kutalika, Kulongedza, ndi Kutumiza Rebar

Kutalika Kwanthawizonse

Mtundu wa Phukusi
Mapaketi otayirira - a mipiringidzo yayikulu
Matabwa omangiriridwa - njira yotchuka kwambiri yotumizira zidebe ndi katundu wambiri
Rebar yozungulira yozungulira (ma diameter ang'onoang'ono - 6-10 mm kapena ofanana, yoyenera kugwiritsidwa ntchito yokha)

Malangizo Osankha Rebar Yabwino Kwambiri pa Pulojekiti Yanu

Kuchokera pamalingaliro ogula ndi uinjiniya:

Yang'anani malamulo a kapangidwe ndi zofunikira zotsatizana ndi malamulo am'deralo musanasankhe magiredi.
Pa nyumba zomwe zimagwedezeka kapena zomwe zili ndi chitetezo champhamvu, ganizirani za kulimba kokha osati kulimba.
Yang'anani ngati zikugwirizana ndi miyezo/dongosolo la kukula kwa mipiringidzo/kutalika kwa zinthu zomwe mukufuna kutumiza kunja.

Kutalika koyenera ndi kulongedza bwino zinthu kungalepheretsenso kuwononga zinthu ndikuchepetsa ndalama zoyendetsera zinthu.

Ngakhalechogwirira chachitsulondi zipangizo zomangira zokhazikika, magiredi osiyanasiyana, kukula kwa makina, ndi miyezo ya madera zingakhudze kwambiri mtengo wa polojekiti, kutsata malamulo, ndi magwiridwe antchito a nyumba.
Kwa ogula zitsulo ndi akatswiri omanga, kumvetsetsa kusiyana kumeneku kumatanthauza mapangidwe otetezeka, kugula mosavuta, komanso kupeza phindu labwino.
