Sei, Nguva uye kupi Kwokucheka Krete
Kuona kupeta inzira yekuita nhengo mukrete . Concrete akaona kucheka kunofanira kuitwa panzvimbo yakatarwa yekugadzirisa kupenga nemhaka ye shrinkage. Zvinonyanya kukosha kugadzira konkrete mushure mokunge yawana simba rakakwana kuti richengetedze rive raveling asi zvisati zvaitika zvinogona kuiswa mukati. Nguva yekucheka kwekaona inokosha kuti usapwanyika mukrete usati wacheka. Kusarudza nguva yekuona yakagadzirwa nekrete kunobva kune rudzi rweadmixtures , kutonhora, kusanganiswa nekugadzira.
Iwe Nokukurumidza Unogona Sei Kugadzira Kontekiti?
Concrete saw cut cut timing inobva pane zvimwe zvinhu zvakadai sokuoma, blade type, weather conditions, concrete mix design uye aggregate size . Kana iwe watanga kuona kucheka konkrete kusvika pakutanga, ungangodaro uchikonzera kupisa, kana uchinge watarisa kunonoka kuchaita kuti usagadziriswe kusadzora. Mumamiriro okunze anopisa, kuona kucheka kunotanga mushure meawa zvichienderana nekushandiswa kwekrete. Wakaona aigona kuedza kuita zvidzidzo zvekuedza kuti aone kana krete yakagadzirira kuonekwa yakatemwa. Kuona kutema kunofanira kutanga nokukurumidza apo kunonoka kunomira panguva yekucheka kwekuedzwa. Kana ibha yekrete yakakura zvikuru, ungada kuva nemashizha akawanda kuti ashande munzvimbo dzakasiyana panguva imwe chete. Vamwe vanononoka makontiniti kuona nekuchengetedza midziyo yavo uye vakaona muchero kuti kuderedza kubhururuka kwemavara. Kune mhando dzakawanda dzemaona akaonekwa anogona kushandiswa zvichienderana nekodhi yakashandiswa uye kuti zvakakonzerwa sei izvi zvinogona kutanga.
Dzivisa kubatana kwakasanganiswa ne:
- Kusimudza chikamu chakanyanya kuoma
- Akaona kucheka pahupamhi
- Kushandisa saga ne ben spindle
- Kushandisa yakashata yakaona blade
Sarudza Kuti Ndezvipi Zvaungaona Kucheka
Usati watanga kuona kucheka konkrete, zvinokosha kusarudza kuti izvi zvakagadzirwa zvichaitwa. Inokurudzirwa kutanga maona kucheka pane kana pakati pepakati yemakoronike.
Majoini achaparadzaniswa pamasikati 24 kusvika ku 36 kuburitsa kwechirabhu asi izvi zvinoda kusimbiswa neanjiniya. Nzvimbo yakatarisana inowanzosvika pakati pe10 kusvika ku18 mamita zvichienderana nehuwandu hwekusimbisa iyo slab ine. Kana iwe uri kushandisa high shrinkage concrete, iwe unogona kuda kuderedza nzvimbo yekucheka. Heano zvimwe zvikonzero zvingakubatsira kuti uone kuti ungaona kupi kutemwa:
- Edza kuita zvikwereti zvikwereti
- Itai kuti zvigadzirwa zvione zvakapfuurira
- Zvakakosha kusarudza nzvimbo isina chekusimudzira simbi kusimbiswa kubva kune rimwe brasb kana kukwereka kune imwe
- Zviri nani kuva nemapundu maduku kudarika kuwedzera mari kuburikidza nekuve nekuchengetedza zvinyorwa zvakawanda.
- Mumamiriro okunze anopisa, ungada kuedza kuumba girasi rakakura ndokuzocheka mapurisa emukati. Nokuita izvi iwe uchave uchidzora nekutsvaga kwekugadzirisa zvikwani zvakakosha munzvimbo dzakawanda.
Nzira Yokugadzira Cut Concrete
Kana uchinge wakaziva majoini kuti aone akachekwa, evhare iwo achishandisa chinyorwa. Kana ukashandisa mvura yekucheka midziyo, iva nechokwadi chokuti mvura iri kufamba ichienda kumhara. Ita kuti blade iwane yakadzika yayo inoda uye tanga kufamba kana kutamisa zvishandisi zvinotevera chiko sechiratidzo. Heano mamwe mazano apo wakaona kudhonza konkrete:
- Usamanikidza jasi rakaona.
- Musarega chikoro chikaputika mucheka, sezvo izvi zvichange zvichiwedzerwa kupfeka pachisungo.
- Paunenge uchicheka konkrete nejeri rebar use blades ne soft metal segment bonds
- Paunenge uchicheka konkrete nemagetsi ekushandisa zvakanyanya rebar ne soft soft segment bonds anoshandiswa inoshandiswa PPE .
Iyo Yakaderedzwa Yakagadzikana Zvakadini?
Murairo wakanaka wegunwe ndewekucheka hutatu kwekota kusvika kune chetatu kuwanda kwe slab. Cherechedza kuti zvakadzama zvakaderedzwa zvakagadzirwa uye zvakakosha uye maererano nehuwandu hwekugadzirisa inyanzvi. Kana kubatana kwakadzika zvakanyanya, kupindira kwezvikwata hazvingakwanisi kutakura mitoro. Zvisinei, apo iyo yakave yakatemwa isiri yakajeka, kuparara kwechirwere kunogona kuitika. Zvinhu zvakadai sekuporesa maitiro , kubata kwebhande, urefu hwechirabhu, uye rudzi rwezasi hunofanira kuongororwa vasati vasarudza apo mapepa aya anofanira kuderedzwa.
