Uyifunda njani imitha yokufuma? Itshathi yokufunda + iingcebiso

Kumashishini amaninzi, kubaluleke kakhulu ukumisela umxholo wokufuma. Ngokomzekelo, kwikhonkrithi, iithayile, iinkuni, ukubuyisela, njl., umswakama unokuchaphazela umsebenzi kakubi.

Kukho iindlela ezahlukeneyo zokumisela umxholo wokufuma, kwaye phakathi kwazo, usebenzisa i imitha yokufuma yeyona ndlela idumileyo.

Ukuba ufuna ukusebenzisa imitha yokufuma, ke kufuneka ube nombono ocacileyo malunga netshati kunye neentlobo ezahlukeneyo zezikali zokufunda ukufuma.

Kweli nqaku, ndiza kuxubusha ngokweenkcukacha indlela yokutolika izikali ezahlukeneyo zokufuma.

Isikali sereferensi

Izikali zokufunda ukufuma ziyilelwe ukumisela ubungakanani obuthile, bobungakanani bokufuma (%MC) kudidi oluthile lwemathiriyeli. Isikali sereferensi sinceda ukubonelela ngoqikelelo olusemgangathweni lokufuma kwiintlobo ezahlukeneyo zemathiriyeli.

Ezinye iimitha zokufuma sebenzisa uluhlu ukusuka ku-0-100 kwaye abanye basebenzisa uluhlu olusuka ku-0-300. Kukho iindlela ezininzi zokusebenzisa imitha yokufuma enereferensi yesikali, esinje:

• Isikali sereferensi yenzelwe ukusetyenziswa kwizinto ezahlukeneyo zokwakha. Ngoko awudingi isikali sereferensi esahlukileyo ukulinganisa umthamo wokufuma weemathiriyeli ezahlukeneyo. Isikali esinye sereferensi sanele.
• Izikali zokubhekisela zikhethwa ngakumbi ukugqiba ukuba ingaba impahla yomile kakhulu okanye imanzi kakhulu. Ukufundwa kwezinto ezomileyo kunokusetyenziswa njengereferensi kwixesha elizayo.
• Ingasetyenziselwa ukujonga isiqulatho sokufuma esikhoyo emhlabeni. Imitha yokufuma edumileyo ebizwa ngokuba yiDelmhorst's KS-D1 imitha yokunyakama komhlaba isebenzisa isikali sereferensi (kunye neebhloko ezikhethekileyo ze-gypsum sensor) ukufumanisa isiqulatho sokufuma esikhoyo emhlabeni.

Isikali sokhuni

Ukususela kwigama, kuyacaca ukuba isikali somthi sisetyenziselwa ukugqiba umthamo womswakama kwizinto zokhuni. Isetyenziswa ngokuqhelekileyo kwimigangatho, ulwakhiwo, amaplanga, kunye namashishini okubuyisela.

Ngokubanzi, izikali zomthi zilinganiswe ukuze zigqume uluhlu olusuka kwi-6% ukuya kuma-40% kwisiqulatho sokufuma. Kukho abazinikeleyo iimitha zokufuma iinkuni.

Isikali se-Drywall

Izikali zeDrywall zisetyenziselwa ukumisela ubumanzi bokwakha, ukuhlolwa kwekhaya, kunye ukonakaliswa kwamanzi amashishini okubuyisela. Isebenzisa isikali sereferensi kwaye yenza uthelekiso kunye nezinto ezomileyo ukumisela ubungakanani bokufuma obukhoyo.

I-drywall eyakhiwe kakuhle kufuneka ibe nobumanzi obungaphantsi kwe-1%. Kungenxa yoko ukuba inani lokufuma lisuka kwi-0.1% ukuya kwi-0.2%, i-drywall scales inokuyibona ngokuchanekileyo.

Uyazi ukuba i-gypsum yenye yezona zinto zisetyenziswa kakhulu zokwakha kwaye inochuku kakhulu emanzini. Isicelo esimangalisayo semitha yesikali se-drywall sijonga umgangatho wokufuma weGyp-Crete flooring kuba iimitha ze-drywall zilinganiswe ukulinganisa ukufuma kwesi sixhobo.

Jonga le vidiyo nguYouTuber WagnerMeters ukubona indlela yokusebenzisa imitha yokufuma eyomileyo:

Hay isikali

Njengoko igama libonisa, imitha yokufuma yesikali se-hay isetyenziselwa ukubona ukufuma kwefula. Uluhlu lwesikali sefula luhlala luphakathi kwe-6% ukuya kwi-40%.

Kusebenza kakuhle ukulinganisa ukufuma kwefula.

Izikali zeHay zithandwa phakathi kwamafama kunye nabasasazi befula.

Isikali sephepha

Kubenzi bephepha, ukugqiba umxholo wokufuma kubaluleke kakhulu ukuvelisa amaphepha asemgangathweni.

Isiqulatho sokufuma semathiriyeli ekrwada esetyenziselwa iphepha kufuneka sihlale kuluhlu oluthile ukuthintela ukuwohloka. Kule njongo, umlinganiselo wephepha usetyenziswa.

I-Pin vs imitha yokufuma engenaphini

Kukho iintlobo ezi-2 eziphambili zeemitha zokufuma: uhlobo lwe-pin kunye ne-pinless.

Njengoko igama lisitsho, iimitha zokufuma zohlobo lwepin zinezikhonkwane ezi-2 okanye ngaphezulu ezigqobhoza imathiriyeli. Yiloo ndlela ufumana ukufundwa kokufuma.

Iimitha zokufuma ezingenaziphini azisebenzisi naziphi na izikhonkwane. Endaweni yoko, basebenzisa amaza e-electromagnetic, okuthetha ukuba awudingi ukungena kuyo nayiphi na into.

Njengoko unokucinga, banezinto zabo ezilungileyo kunye neengxaki zabo. Bavavanye ukufumanisa ukuba sesiphi esona sixhobo silungileyo somsebenzi.

FAQs

Nayi eminye imibuzo ebuzwa rhoqo kunye neempendulo zayo.

Ukufundwa kwemitha yokufuma okuqhelekileyo emthini kuphakathi kwe-6% kunye ne-10%. Nangona kunjalo, kwi-drywall, ikhonkrithi, kunye ne-masonry substances, imitha yomswakama kufuneka ibonise amaxabiso aphantsi (ngokukhethekileyo ngaphantsi kwe-1%).

Yintoni ufundo lokufuma olwamkelekileyo?

Ukwazi iimeko zokufuma (RH) kuyimfuneko xa uzama ukufumanisa ukuba yintoni "ekhuselekileyo" isiqulatho sokufuma kwiindonga zokhuni. Ngokomzekelo, ukuba iqondo lokushisa kwigumbi lijikeleze i-80 F, kwaye i-RH yi-50%, ngoko inqanaba "elikhuselekileyo" lokufuma eludongeni liya kuba malunga ne-9.1% MC.

Yintoni ekufuneka ifundwe ngomswakama owomileyo?

Ngelixa ukufuma okunxulumeneyo kunokuba nefuthe elithile kumanqanaba okufuma, i-drywall ithathwa njengenqanaba elifanelekileyo lokufuma ukuba inomthamo wokufuma ophakathi kwe-5% kunye ne-12%.

Ichane kangakanani imitha yokufuma?

Imitha yokufuma ekumgangatho ophezulu esetyenziswe kwinto elungileyo inokuchaneka ibe ngaphantsi kwe-0.1% yomxholo wokufuma ngobunzima. Nangona kunjalo, imitha yokufuma esezantsi isenokungachani ngokwendalo.

Ngowuphi umgangatho wokufuma oqhelekileyo endlwini?

Kubalulekile ukugcina amanqanaba okufuma afanelekileyo kwikhaya lakho nakwindawo yokusebenza ukuze ugcine indawo etofotofo, esempilweni. Amanqanaba okufuma ngaphakathi endlwini kufuneka abe phakathi kwe-30% ukuya kwi-50%, kunye nenqanaba elifanelekileyo malunga ne-45%.

Yintoni ufundo lokufuma olwamkelekileyo kwimigangatho yomthi oqinileyo?

Ukuqinisekisa ukuba imigangatho yakho yokhuni oluqinileyo ifuna ukuchaneka, ungasebenzisa uvavanyo lokunyakama komgangatho womthi. Okokuqala, vavanya inqanaba lokufuma kwe-subfloor.

Ngokubanzi, ukufuma kwe-12% okanye ngaphezulu kumanzi kakhulu ukufaka umgangatho. Ngokufanelekileyo, kufuneka ibe phakathi kwe-7% kunye ne-9%.

Ngowuphi umgangatho owamkelekileyo wokufuma kwikhonkrithi?

I-MFMA indulula ukuba umgangatho wokufuma onxulumeneyo we slab yekhonkrithi yenkqubo yomgangatho wemaple engagxumekiyo ube ngama-85% okanye ngaphantsi. Kwiinkqubo zeglue-down, inqanaba le-concrete ye-concrete yokufuma kufuneka ibe yi-75% okanye ngaphantsi ngaphambi kokufakwa.

Uwubala njani umxholo wokufuma?

Ubungakanani bamanzi bunqunywe ngokususa ubunzima obomileyo ukusuka kubunzima bokuqala. Emva koko, umthamo womswakama ubalwa ngokwahlula ubungakanani bamanzi ngobunzima obomileyo okanye ubunzima obupheleleyo, kuxhomekeke kwindlela yokubika.

Ngaba iimitha zokufuma zifanelekile?

Iimitha zokufuma zixhomekeke ekufundweni okungeyonyani ngenxa yezizathu ezininzi ezibhalwe kakuhle kushishino. Iimitha ezingenayo i-invasive zinezinto ezikhohlisayo ezingaphezu kweemitha ezingenayo.

Eyona nto ixhaphakileyo yintsimbi efihlwe ngaphakathi okanye ngasemva kwezinto ezijongwayo.

Umngundo ukhula kweliphi inqanaba lokufuma?

Ngamanye amaxesha, ukufuma okanye ukufuma (umphunga wamanzi) emoyeni kunokubonelela ngokufuma okwaneleyo kokukhula komngundo. Ukufuma okunxulumene nendlu (RH) kufuneka kugcinwe ngaphantsi kwe-60%; ngokufanelekileyo, phakathi kwe-30% kunye ne-50%, ukuba kunokwenzeka.

Ngaba iimitha zokufuma ezingabizi kakhulu zilungile?

I-25-50 ye-pin yodidi lwemitha engabizi kakhulu ilungele ukulinganisa iinkuni. Ukuba uzimisele ukwamkela ukufundwa kokufuma nge +/- 5% ngokuchanekileyo, unokuhamba ngokuthenga imitha yexabiso eliphantsi kuluhlu lwe-25-50 yeedola.

Ke i-25-50 ye-pin yodidi lwemitha yokufuma ilungele iinkuni.

Yeyiphi eyona mitha echanekileyo yokufuma?

I-Calculated Industries 7445 AccuMASTER duo pro meter yeyona mitha ichanekileyo yokufuma. Imitha yokufuma enemisebenzi emininzi inephini engenaphini yokuvavanya indawo enkulu, kunye nokutshintshela kwisitayile sokulinganisa isikhonkwane sovavanyo oluchanekileyo olungaphakathi kwe-3% kubunzulu obahlukeneyo.

Ngaba iimitha zokufuma komhlaba zikufanele oko?

Iimitha ziya kukuxelela ukuba umhlaba umanzi, ufumile, okanye womile kwinqanaba leengcambu, nto leyo eyenza ukuba isebenze ngakumbi kwizityalo ezinkulu zembiza. Ezinye izixhobo zokujonga ukufuma komhlaba, ezidla ngokusetyenziswa kwizicelo zezolimo, ziquka i-tensiometers kunye neebhloko zokunganyangeki kombane, ezibonisa ukuxinana kokufuma komhlaba.

Ngoko ukuba zifanelekile kuwe kuya kuxhomekeka ekubeni unzulu kangakanani malunga nokufuma komhlaba.
