Ishidi lokufulela elihlanganisiwe elihlanganisiwe le-SGCC/CGCC ishidi lokufulela elihlanganisiwe elinombala oshisayo othengiswayo
Izici
⒈ Isisindo esincane: 10-14 kg/m2, okulingana ne-1/30 yodonga lwezitini.
⒉ Ukushisa: λ<=0.041w/mk.
⒊Amandla aphezulu: Ingasetshenziswa njengebhodi elithwala umthwalo wesakhiwo sophahla oluvalekile, elimelana nokugoba nokucindezelwa; imishayo namakholomu akusetshenziswa ezindlini ezijwayelekile.
⒋Umbala okhanyayo: akudingeki umhlobiso womphezulu, futhi ungqimba olulwa nokugqwala lwepuleti lensimbi elinombala ogqanyisiwe lungagcinwa iminyaka eyi-10-15.
⒌Ukufakwa kuyaguquguquka futhi kuyashesha: isikhathi sokwakha singafinyezwa ngaphezu kuka-40%.
Faka
Ifomula yokubala umthamo
1. Uphahla olugobile olunezinhlangothi ezimbili
Incazelo yophahla olugobile olunezinhlangothi ezimbili
⒈Indawo yophahla: ubude × ububanzi.
⒉Ubude obuphelele bethayela elidingekayo: indawo yophahla ÷ 0.855 (ububanzi obusebenzayo bethayela bungu-0.855M/isiqephu).
⒊Inani lamathayili: (ubude bophahla ÷0.855m)×2.
⒋Inani lamathayela onqenqema: ubude bophahla ÷ 2.4m (ubude obusebenzayo bamathayela onqenqema bungu-2.4M/impande).
⒌Inani lemicu yokuvala: (ubude ÷ 0.7m) × 2 (umucu wokuvala 0.7M/isiqephu).
⒍Ubuningi besimbozo se-eves: (ubude ÷ 0.7m) × 2 (i-eves isimbozo 0.7M/isiqephu).
⒎Inani lezipikili ezikhethekile: 4PCS/㎡.
⒏I-engeli yophahla ingaphansi noma ilingana nama-degrees angu-120.
2. Uphahla olugobile olunezinhlangothi ezine
Incazelo yophahla olugobile
⒈Indawo yophahla lwesabelomali: (A+B+C+D)×117% (ukuthambekela nokulahlekelwa).
⒉Ubude obuphelele bethayela elidingekayo: indawo yophahla ÷ 0.855 (ububanzi obusebenzayo bethayela bungu-0.855M/isiqephu).
⒊Inani lamathayela omugqa: (a×2+b+c×2) ÷ 0.7 (ubude obusebenzayo bamathayela omugqa bungu-2.4M/isiqeshana).
⒋Inani lemicu yokuvala: (ubude + ububanzi) ÷ 0.7 (umucu wokuvala 0.7M/isiqephu).
⒌Inombolo yesembozo semiphetho: (ubude + ububanzi) × 2÷0.7 (imiphetho isembozo 0.7M/isiqephu).
⒍Inani lezipikili ezikhethekile: 4PCS/㎡.
Ubunjiniyela bangaphambi kokufakwa
Umthambeka onezinhlangothi ezine
1: Umugqa oluhlaza okwesibhakabhaka onezinhlayiya kanye nomugqa obomvu onezinhlayiya kuyizinhlaka ezivundlile neziqondile ngokulandelana.
2: a Ibanga elihle kakhulu lingu-50CM.
3: Ibanga lika-b kungcono libe ngu-50-70CM.
Izinhlangothi ezimbili ezithambekele
⒈Khetha izinto zohlaka, kokubili isakhiwo sokhuni nesakhiwo sensimbi kufanelekile.
⒉Umphezulu wokwakha udinga ukuhlanzwa nokuhleleka.
⒊Imininingwane yezinto zohlaka: Imininingwane yokhuni ingu-45MM×45MM noma ngaphezulu, imininingwane yensimbi ingu-40MM×40MM noma ngaphezulu.
⒋ Isikhala eside sohlaka kufanele sigcinwe phakathi kuka-50CM ~ 70CM, kanti isikhala esivundlile kumele sibe yi-multiple engu-25CM, okungcono singabi ngaphezu kuka-50M. Sebenzisa izikulufo eduze ngangokunokwenzeka bese uzihlanganisa ngokuqinile.
Umsebenzi wokufaka
Indlela efanele yokubeka amathayili
⒈Uhlobo lokuhlanganisa (olusebenza ophahleni olunobude obungu-≦15M)
Uhlobo olugobile (olusebenza ophahleni olunobude obungu-≧15M)
Ukusetshenziswa okufanele kwezipikili ezikhethekile
⒈Isipikili esikhethekile kumele sishaywe phakathi kwethambo lethayela ukuze kube nomphumela wokungangeni manzi.
⒉Isikhathi esinqunyiwe sezipikili ezikhethekile singama-50cm ~ 100cm (kungcono izingcezu ezi-4/㎡).
⒊Izipikili ezikhethekile kumele zishayelwe kusukela ekugcineni kwethayela kuya ophahleni ukuze zibe nomphumela omuhle, ovalwe kahle futhi ococekile.
Faka isembozo sethayela le-sealing strip ridge
⒈ Hlukanisa umucu wokuvala phakathi, bese ubeka amathayili onqenqemeni ophahleni ngokohlobo lwethayili bese uwalungisa ngezipikili ezikhethekile.
⒉Izihlanganisi zamathayili aseceleni zivalwe ngesimende bese zimbozwa ngqo ngamathayili aseceleni, bese kuthi phansi kwamathayili aseceleni kuqedwe ngethayili elincane eliyindilinga.
⒊Ingxenye engezansi yethayela, okungukuthi ama-eves, ifakwe ngqo ngesembozo sama-eves futhi iqiniswe ngezikulufo.
4. Endaweni yokuhlangana kwethayela eliseceleni, isikhombikubona sokungafani sihlotshiswe ngesikele bese sihlanganiswa futhi sivalwe ngeglue yengilazi.
Ukwelashwa okungangeni manzi kwengxenye ephumayo
Okokuqala, yenza izinto ezimise okwe-V. Izinto ezahlukene kanye nezincazelo zingakhethwa, kuye ngesimo sangempela. Ngemva kokufaka uxhumano lwamanzi phansi, beka amathayili ensimbi anombala phezulu.
Ukufakwa koxhumano endaweni ethambekele
Kubhekiselwa ekwakhiweni lapho amathayela ophahla amabili asikwa khona ngokwe-engeli nobude, bese kuthi phansi kufakwe ukwelashwa kokwamukela amanzi. Okokuqala, faka izinto zokwamukela amanzi (okungukuthi i-gutter) ngaphansi kwamathayela, bese usebenzisa inhlaka engangeni manzi noma usimende ukuze uqedele.
Izinyathelo zokuzivikela
1. Gqoka izinto zokuphepha ezidingekayo (njengamagilavu, izigqoko zokuzivikela, amabhande okuphepha kanye namanye amathuluzi).
2. Isisebenzi sokufaka sidinga ukuba uchwepheshe onesitifiketi.
3. Uhlaka kumele luqine uma lufakwa.
4. Uma ufaka futhi uhamba phezu kwamathayili, zama ukunyathela engxenyeni ephakathi yamathayili ukuze ugweme ukunyathela emaphethelweni amathayili.
5. Qaphela ukufaka uma isimo sezulu sibi.
