6 dhaka rinozvimisa
Kuzvimisikidza dhaka: iri pachigadziko chisina kuenzana (sepamusoro pekugadzirisa, dhaka redhaka, nezvimwewo), ichipa yakakodzera flat, yakatsetseka uye yakasimba yekurara yekumisa zvinhu zvakasiyana-siyana zvepasi.Zvakadai seyakanaka kuenzanisa zvinhu zvemakapeti, matanda pasi, PVC, ceramic mataira, etc. Kunyangwe kune nzvimbo huru, inogona zvakare kuvakwa zvinobudirira.
7 dhaka risina mvura
Ndeyesimende-based waterproof material.Iyo isingapinde mvura zvinhu zvinonyanya zvinosanganisira simende uye mafirita.Inogona kusangana nezvinodiwa zvisingaite mvura nekuwedzera mapolymer, additives, admixtures kana yakaoma-yakasanganiswa dhaka yakasanganiswa nesamende yakakosha.Rudzi urwu rwezvinhu rwave JS composite isina mvura yekunamira pamusika.
8 kugadzirisa dhaka
Mamwe madhaka ekugadzirisa anoshandiswa kushongedza kugadzirwa kwekongiri isina simbi simbi uye isina basa rekutakura mutoro nekuda kwezvikonzero zvekunaka, uye mamwe anoshandiswa kugadzirisa akakuvadzwa anotakura-akasimbisa kongiri zvivakwa kuitira kuchengetedza uye kumisazve kugadzikana kwechimiro. uye mabasa.Chikamu chekongiri yekugadzirisa system, inoshandiswa pakugadzirisa uye kudzorerwa kwemabhiriji emigwagwa, nzvimbo dzekupaka, tunnels, nezvimwe.
9 Putty yemukati nekunze madziro
Putty ivhu rakatetepa redhaka rekuenzanisa, iro rakakamurwa kuita chimwe-chikamu uye maviri-chikamu.Zvinhu zvekubatsira zvekushongedza zvekushongedza pendi, inoshandiswa pamwe chete nependi yelatex.
10 caulk
Iyo inonziwo grouting agent, inoshandiswa kuzadza zvinhu zvakabatana pakati pematairi kana dombo rechisikigo, kupa aesthetic pamusoro uye chisungo pakati anotarisana mataira, seepage kudzivirira, etc. Inodzivirira tile base zvinhu kubva mechanical kukuvadzwa uye migumisiro yakaipa yekupinda kwemvura.
11 grouting zvinhu
Cement-based grouting material ine basa rekubhadhara shrinkage, ne micro-expansion, micro-expansion inoitika muplastic stage uye kuoma nhanho kubhadhara shrinkage.muviri wakaoma.Yakanaka fluidity inogona kuwanikwa pasi yakaderera mvura-simende reshiyo, iyo inobatsira kuvaka kudira uye kugadzirisa kuzora kuvaka.
Kuongororwa kwematambudziko akaoma-akasanganiswa ematope
Parizvino, dhaka yakaoma-yakasanganiswa iri padanho rekukurumidza kukura.Kushandiswa kwedhaka rakaoma-musanganiswa kunogona kunyatso kudzikisa kushandiswa kwezviwanikwa, kunatsiridza mhando yepurojekiti, uye kugadzirisa nharaunda yemudhorobha.Zvisinei, kuchine matambudziko akawanda ehutano mumatope akaoma-akasanganiswa.Kana iyo isingaenzaniswi, zvakanakira zvayo zvichaderedzwa zvakanyanya, kana kunyange zvinopesana.Chete nekusimbisa hutongi hwemhando muzvinhu zvakasiyana senge zvigadzirwa, zvigadzirwa zvakapedzwa, nenzvimbo dzekuvaka, izvo zvakanakira uye mabasa edhaka rakasanganiswa-akasanganiswa anogona kunyatsounzwa mukutamba.
Kazhinji chikonzero chekuongorora
1 mutswe
Kune marudzi mana ezvinonyanya kutsemuka: base isina kuenzana settlement cracks, tembiricha makatsemuka, kuomesa shrinkage makatsemuka, uye epurasitiki shrinkage mutswe.
Kusagadzikana kwekugara kwe base
Kugadzika kusina kuenzana kwehwaro kunonyanya kureva kutsemuka kunokonzerwa nekudzika kwemadziro acho.
kupisa kwekushisa
Iko kushanduka kwekushisa kunokonzeresa kuwedzera kwekupisa uye kuputika kwezvinhu.Kana tembiricha kushushikana kunokonzerwa nekushisa deformation pasi pemamiriro ekumanikidza yakakura zvakakwana, madziro anoburitsa tembiricha yakatsemuka.
kuomesa shrinkage mitswe
Drying shrinkage cracks dzinonzi drying shrinkage cracks kwenguva pfupi.Sezvo mvura yemukati yemasonry senge aerated kongiri zvidhinha uye nhunzi madota zvidhinha zvadzikira, zvinhu zvacho zvinoburitsa hombe yekuomesa shrinkage deformation.Iyo shrinkage zvinhu zvicharamba zvichiwedzera mushure mekunyorova, uye zvinhu zvacho zvinozodzikira nekuremara zvakare mushure mekupera mvura.
kupera kwepurasitiki
Chikonzero chikuru chepurasitiki shrinkage ndechokuti mukati mechinguva chiduku mushure mokunge dhaka rakaputirwa, shrinkage stress inogadzirwa apo unyoro hunoderedzwa kana huri mupurasitiki.Kamwe shrinkage stress inodarika simba rekunamatira revhu pacharo, kuputika kuchaitika pamusoro pechimiro.Iyo yepurasitiki yekuomesa shrinkage yesosi yekupurasita inokanganiswa nenguva, tembiricha, hunyoro hunoenderana uye mwero wekuchengetedza mvura yedhaka rekupurasita pacharo.
Pamusoro pezvo, kuregeredza mukugadzira, kutadza kumisikidza giredhi mitsetse zvinoenderana nezvinodiwa, zvisingatarisirwe anti-kutsemuka matanho, husina kukodzera mhando yezvinhu, husina kunaka hwekuvaka, kutyorwa kwedhizaini nemirau yekuvaka, simba remasonry risiri kusangana nezvinodiwa zvekugadzira, uye kushomeka. yeruzivo zvakare Chinhu chakakosha chekutsemuka mumadziro.
2 mhango
Pane zvikonzero zvina zvikonzero zvekuchera: pamusoro pemadziro echigadziko haagadziriswe, rusvingo rwakareba kwazvo kuti rwuroverwe nekuda kwekusakwana kwekugadzirisa nguva, iyo imwe chete yepurasita yakanyanya kukora, uye purasita inoshandiswa zvisina kunaka.
The base wall surface haina kurapwa
Guruva rakanamira pamadziro, dhaka rasara uye mumiriri wekuburitsa panguva yekudururwa harina kucheneswa, nzvimbo yakatsetseka yekongiri haina kupendwa neinterface agent kana kupfapfaidzwa nekupushwa, uye mvura haina kunyatsonyoroveswa isati yapurasita, nezvimwe. ., ichakonzera hollowing Phenomenon.
Kana nguva yekuchengetedza rusvingo isina kukwana, inoda kuisa.Kurovera kunotanga madziro asati anyatsoremara, uye kuderera kwechigadziko chepasi uye kupurasita hakuenderane, zvichiita kuti pave negomba.
Single layer plaster yakanyanyisa
Kana madziro akati sandara asina kunaka kana kuti pakaremara, hapana kufanorapwa, uye kupurasita kunoda kubudirira, uye kunorarama panguva imwe chete.Iyo plastering layer yakakora zvakanyanya, zvichiita kuti shrinkage stress ive yakakura kudarika simba rekubatanidza redhaka, zvichiita kuti pave neburi.
Kusashandiswa zvakanaka kwezvinhu zvekupurasita
Simba rekupurasita harina kufanana nesimba remadziro echigadziko, uye musiyano mukuputsika wakakura kwazvo, ndicho chimwe chikonzero chegomba.
3 Jecha kubva pamusoro
Kurasika kwejecha pamusoro kunonyanya kukonzerwa nechikamu chidiki chesimende zvinhu zvinoshandiswa mudhaka, jecha fineness modulus yakadzikira, madhaka emukati anodarika mwero, simba revhu harina kukwana kukonzera jecha, chiyero chekuchengetedza mvura dhaka rakanyanya kuderera uye kurasikirwa kwemvura kunokurumidza, uye kugadzirisa mushure mekuvaka hakusi panzvimbo.Kana kuti hapana kuchengetedza kunokonzera kurasikirwa kwejecha.
4 kusvuura hupfu
Chikonzero chikuru ndechekuti chiyero chekuchengetedza mvura yedhaka hachina kukwirira, kugadzikana kwechikamu chimwe nechimwe mumatope hakuna kunaka, uye chikamu chemusanganiswa unoshandiswa chakakura kwazvo.Nekuda kwekukwesha uye necalendering, humwe hupfu hunoyangarara kumusoro uye hunoungana pamusoro, kuitira kuti simba repamusoro rive shoma uye Powdery ganda.
