Kodi reinforcing mesh ndi chiyani?
Kulimbitsa ma mesh ndi njira yogwiritsira ntchito nsalu zachitsulo zowotcherera ngati kulimbikitsa zinthu zomangika za konkriti monga ma slabs a konkriti ndi makoma. Kulimbitsa mauna nthawi zambiri kumabwera mumtundu wa rectangular kapena square grid ndipo amapangidwa m'mapepala athyathyathya.

1. Wapadera, kukana kwa chivomezi chabwino komanso kukana ming'alu. Kapangidwe ka mauna opangidwa ndi mipiringidzo yayitali komanso mipiringidzo yopingasa ya mauna olimbikitsira amalumikizidwa mwamphamvu. Kumangirira ndi kumangirira ndi konkire ndikwabwino, ndipo mphamvuyo imafalitsidwa mofanana ndikugawidwa.
2. Kugwiritsa ntchito kulimbikitsa mauna pomanga kungapulumutse chiwerengero chazitsulo zazitsulo. Malinga ndi zochitika zenizeni za uinjiniya, kugwiritsa ntchito kulimbikitsa mauna kumatha kupulumutsa 30% yazomwe zimagwiritsidwa ntchito ndizitsulo, ndipo mauna ndi yunifolomu, waya wam'mimba mwake ndi wolondola, ndipo mauna ndi athyathyathya. Pambuyo kulimbikitsa mauna kufika pamalo omanga, angagwiritsidwe ntchito mwachindunji popanda kukonza kapena kutayika.
3. Kugwiritsa ntchito ma mesh ochiritsira kumatha kufulumizitsa kwambiri ntchito yomanga ndikufupikitsa nthawi yomanga. Pambuyo polimbitsa mauna aikidwa malinga ndi zofunikira, konkire ikhoza kutsanuliridwa mwachindunji, kuchotsa kufunikira kwa kudula pamalopo, kuika, ndi kumanga m'modzi ndi mmodzi, zomwe zimathandiza kupulumutsa 50% -70% ya nthawiyo.

Kugwiritsa ntchito

1. Kugwiritsa ntchito kulimbikitsa mauna mu uinjiniya wamsewu waukulu wa simenti

Kutalikirana kocheperako komanso kutalikirana kokulirapo kwa mauna omangirira pamapando a konkriti omangika ziyenera kutsata miyezo yamakono yamakampani. Mipiringidzo yachitsulo yozizira ikagwiritsidwa ntchito, mipiringidzo yachitsulo yachitsulo siyenera kuchepera 8mm, kutalikirana kwachitsulo kwakutali sikuyenera kupitirira 200mm, ndipo mipiringidzo yachitsulo yodutsa sikhala yayikulu kuposa 300mm. Mipiringidzo yachitsulo yowongoka ndi yopingasa ya mesh wowotcherera iyenera kukhala ndi mainchesi ofanana, ndipo makulidwe a chitetezo chazitsulo zazitsulo sikuyenera kukhala zosakwana 50mm. The welded mauna kwa analimbitsa konkire mwapang'onopang'ono chilimbikitso akhoza kukhazikitsidwa motsatira malamulo oyenera mauna welded kwa analimbitsa konkire m'misewu.

2. Kugwiritsa ntchito reinforcing mesh mu engineering bridge

Amagwiritsidwa ntchito kwambiri pamiyala ya milatho yamatauni ndi milatho yamsewu, kukonzanso zida zakale za mlatho, anti-cracking ya ma piers a mlatho, ndi zina zambiri. Kuwongolera bwino, sitimayo ya mlatho imakhala yopanda ming'alu, ndipo liwiro la msewu ukuwonjezeka Kuposa 50%, kuchepetsa mtengo wapampando wa mlatho ndi pafupifupi 10%.

3. Kugwiritsa ntchito kulimbikitsa mauna mumzere wa ngalande

Malinga ndi malamulo adziko lonse, nthiti zolimbitsa nthiti ziyenera kuikidwa mu shotcrete, zomwe zimathandiza kupititsa patsogolo kukameta ubweya ndi kupindika kwa shotcrete, kupititsa patsogolo kukana nkhonya ndi kupindika kwa konkire, kupititsa patsogolo kukhulupirika kwa shotcrete, ndi kuchepetsa chiopsezo cha shotcrete.
