Purati repamusoro regranite rinobuda mufekitori riine chitupa chekuti rakatsetseka chakabatanidzwa pariri. Mwedzi mitanhatu gare gare, muimba yekuongorora yemutengi, purati iroro rinogona kuyera zvakasiyana - kwete nekuti dombo rakachinja chimiro, asi nekuti imba yakaripoteredza yakachinja. Iyi ndeimwe yenzvimbo dzinozivikanwa, uye dzinogona kudzivirirwa, dzekuyerwa kwemvura mumarabhoritari emetrology.
Granite inosarudzwa pamatafura ekuyera uyezvigadziko zvakaruramanekuti inodzivirira kuchinjika kwechinhu kupfuura simbi yakakandwa kana simbi. Haina ngura, haina kupisa kwakanyanya, uye inonyorovesa kutenderera zvakanaka. Asi "inodzivirira kuchinjika kwechinhu" haina kufanana ne "kusadzivirirwa kwayo." Kusachengetedza zvakanaka - kuchinja-chinja kwetembiricha, hunyoro, rutsigiro rwakasiyana, kana kubata zvisina hanya - kunogona kugadzirisa chinyararire mwedzi yakawanda yekukuya nekurovera ndiro isati yasvika pasi pechitoro chemutengi.
Nei Mamiriro Ekuchengetedza Achikosha Kupfuura Zvinofungidzirwa Nevanhu
Granite ipurasitiki yechisikigo, uye sechero chinhu chakasimba, inopindura kune zvakatipoteredza. Zvinhu zvitatu zvinokonzera matambudziko mazhinji ane chekuita nekuchengetwa kwezvinhu atinoona mumunda:
Kuchinja-chinja kwetembiricha. Kunyangwe paine kuwedzera kwakaderera kwekupisa, granite slab inoonekwa pakuchinja-chinja kwezuva nezuva kwe10–15°C inokura nekukotama padanho re microscopic. Nekufamba kwenguva, kunyanya kana kupisa kusina kuenzana — chiedza chezuva chichirova kumucheto kweplate, kana kuti heater yewarehouse ichitenderera nekudzima — izvi zvinogona kukonzera kutsarukana kunoyerwa, kunyanya pamaplate akakuyiwa kuenda kune sub-micron tolerances.
Kunyorova uye kunyudzwa kwemvura. Granite ine maburi, uye matombo akachipa - kunyanya marble inotengeswa pasi pechinyorwa che "granite" nevatengesi vasina kungwarira - inonyudzwa hunyoro zviri nyore uye inonyanya kukombama uye kusvibiswa pamusoro. Ichi ndicho chimwe chikonzero nei kusarudza zvinhu kuchikosha semhando yekugadzira. Matombo ane huwandu hwakanyanya, ari pakati pe3,000 kg/m³ kana kupfuura, anodzivirira kunyudzwa kwemvura zviri nani pane mamwe magadzirirwo emhando yepasi.
Kutsigira uye kugoverwa kwemutoro. Ndiro yegranite inochengetwa pasi isina kuenzana, kana kuti inotsigirwa pamipendero yayo chete, inodonha nekufamba kwenguva pasi pehuremu hwayo - iyo nheyo imwechete inoshanda kune chero slab yakasimba iri pasi pekuiswa kwenzvimbo kwenguva refu. Matanda marefu akajeka uye maplate makuru anonyanya kunzwisiswa neizvi, sezvo kunyangwe mamirimita mashoma ehupamhi husina kutsigirwa anogona kushandurwa kuita bow inoonekwa.
Kuchengetedza Kwakanaka Kwakaita Sei?
Zvichibva pamakore ekubata zvikamu zvegranite usati wagaya uye wapedza kugaya, maitiro mashoma anogara achiita mutsauko:
- Chengeta maplate panzvimbo dzawo dzakagadzirirwa kutsigira (kazhinji dzine mapoinzi matatu kana mapoinzi eBessel ezvikamu zvirefu), usambofa wakatsetseka panzvimbo isina kuenzana.
- Chengeta tembiricha yemhepo yakagadzikana — zviri nani kuti ive mukati mebhandi rimwe chete iro ndiro ichashandiswa, kudzivirira kuva pedyo nemasuo, mahwindo, kana maburi emhepo eHVAC.
- Dzora hunyoro kudzivirira kufamba kwehunyoro mumasero madiki edombo, kunyanya kumaplate akamirira kucheneswa kwekupedzisira.
- Dzivisa kuisa zvikamu zvegranite zvakananga pamusoro pechimwe nechimwe pasina nzvimbo dzakakodzera; kugunzva kwenzvimbo pasi pehuremu ndicho chikonzero chinowanzo kukonzera kutsemuka uye kushushikana munzvimbo imwe chete.
- Tarisa zvakare kuti plate yacho yakapfava here mushure menguva yakareba yekuichengeta isati yatanga kushanda, pane kufunga kuti chitupa chekutanga chichiri kushanda.
Nzvimbo yedu inoshandisa makamuri anodzora tembiricha nehunyoro kunyanya padanho iri rekugadzira — kwete kungoongororwa kwekupedzisira chete, asiwo maplate ekugadzirisa pakati pema "grinding passes" uye asati atumirwa. Pasi mumakamuri aya pane kongiri yakakora yakasimbiswa, yakaparadzaniswa nechivakwa chakapoteredza ne "seismic-style expansion joints", iyo inodzivirira kudedera nekugadzikana kubva pakukanganisa zvikamu zvakachengetwa. Chinhu chisingaonekwe papepa re "spec", asi kazhinji musiyano uripo pakati peplate inochengetedza kugadzikana kwayo kwemakore uye inoda kudzokororwa mukati memwaka.
Mutoro Wakagovaniswa
Vagadziri vanogona kudzora zvinoitika vasati vatumira. Zvinozoitika mushure mezvo — muchiteshi chekugamuchira vatengi, mudura rinogovaniswa, kana murabhoritari isina kupedza kugadzira kwayo yekudzora mamiriro ekunze — hazvibvi mumaoko emutengesi. Ndicho chimwe chezvikonzero nei magwaro achikosha: zvitupa zvekugadzirisa zvinoteverwa nesangano remetrology rinozivikanwa zvinopa hwaro hwekuyera kubva pane ramangwana, uye kuongororwazve nguva nenguva (gore rega rega, kana mushure mekusangana nenjodzi huru) inzira yakajairika pakati pemarabhoritari anotora kudzokorora kwakakosha.
Matafura ekuyera granite nemaplate epamusoro inguva refu yekudyara chero murabhoritari wekuongorora, imba yeCMM, kana mutsetse wekubatanidza zvakanyatsonaka. Kugadzikana kwechinhu ichi ibhenefiti chaiyo pane dzimwe nzira dzesimbi kana simbi yakakandwa, asi chete kana kugadzikana ikoko kusina kukanganiswa nekamuri raanogara. Kuona nzvimbo yekuchengetera zvinhu sechikamu checheni yekunyatsonaka - pane kufunga nezvekupedzisira kana plate yapasa ongororo yekupedzisira - itsika diki yekushanda inobhadhara hupenyu hwemuchina.
