Inowuthi Uphahla Ubuncinane wetshati trapezoidal: kuvumelekile parameters, ingakumbi ukubala kunye neziphakamiso

Ngenxa yokuba iimpawu zayo ukusebenza kakuhle, iphepha sobhedu ngokubanzi kusetyenziswa kuzo zombini zokwakha zokuhlala kunye nezoshishino. Xa uthobela yonke imigaqo zobugcisa ufakelo kunye nokusetyenziswa kwayo zingenziwa ethembekileyo istili, ixesha elide ezintle kukholekisa uphahla.

Lomenzi iingcebiso: a phula kophahla ubuncinane kuxwebhu trapezoidal

Kwiimeko ezininzi le nto kucetyiswa ukuba kungabekwa phezu kophahla kunye engile ukutyekela izidanga hayi ngaphantsi kwe-20. Lo mgaqo, kunjalo, ikakhulu siphathelele Izakhiwo zokuhlala kuphela. Kwemigangatho zobunjineli industrial sheet intsimbi zingasetyenziswa njenge nophahla Imathiriyeli ezithambekileyo kunye ethambekeni degrees 8. Kodwa kwi uphahla kakhulu kwezakhiwo zoshishino nga mayixhonywe uluhlu eyodwa kuphela - kunye iprofayile self-axhasayo. Nangona kukho izinto ezinjalo kuba kubiza imali ngokufanelekileyo, kwaye ngamanye amaxesha isetyenziswa abucala ekwakheni indlu. Xa isicelo sayo inowuthi ezizezona zisezantsi uphahla lwendlu profiled sheet zokuhlala kunokuba ulingana degrees 15.

Imiphumo-zokungathotyelwa kwemimiselo

Ukuba kuyilo uphahla profiled iyolala iimfuneko isniphu malunga engile ubuncinane reyi, umnini-ndlu elizayo silindele iingxaki ezifana:

• ukuvuza imvula ngokusebenzisa imigodi ngezikhonkwane;
• Ukuhlukunyezwa layers snow kophahla;
• ubushushu ukulahleka kakhulu ngophahla;
• ukuphazamiseka sheets zemimoya olomeleleyo umoya.

abanini kwezithobekileyo yokwenene ipoma bakholelwa ukuba uphahla ngakumbi kakuhle izidanga, i ngaphantsi uya impahla yakhe. Kodwa enyanisweni oku kuyinyaniso. Xa nelungiselelo kuphahla kuyimfuneko kudla ukusebenzisa inani elikhulu kakhulu imiqadi (inqwanqwa-40 cm). Kwakhona kulo mzekelo, izinto sheathing ngokungqinelana nemigaqo, libekwe zinonxibelelwano olukhulu.

Elona pitch lophahla wetshati trapezoidal, njengoko esaziva ngabo ezi ndaba, - degrees 15. Xa eyila, ungakhetha olu khetho kunye nophahla. Kodwa engcono yokwenza ngakumbi zivele amathambeka uphahla. Kulo mzekelo istili ziya kuthembeka ngakumbi, yaye umsebenzi ngokwawo Ufako kwezinto uya kwenza lula. I lusebenze, nokujikeleza engile imitha ngobuwena usebenzisa trapezoidal sheet ithathwa 25-40 cm.

kufuneka ibe yintoni ukudlulela

Esi salathisi kuya kuxhomekeka Kukhethwe uyilo kwi ukuthambeka ekhaya engile stingrays. ukuze:

• ukuba engile degrees-15 ukuya kwi-30 ayangenana kufuneka-20 cm;
• ngokuba nophahla ne-engile degrees 30 okanye ngaphezulu - 15 cm.

Ukuba le projekthi isekelwe phezu inowuthi ubuncinane kophahla, wayenza profiled khazi sheet eyenziwe zidlulela phakathi kwemiqolo ngamaza emibini. Ukongeza, ukukhuselwa lihle ngaphezulu nxamnye ukufuma sealant lisetyenziswa kunye ngetywina okhethekileyo. Ukongeza, kule meko noxwebhu sentsimbi kufuneka libhalwe ebhokisini esiqinileyo.

Iingcebiso malunga nokukhethwa umbandela

kufumaneka ngokorhwebo iintlobo Modern proflist ezimbini ezingundoqo: udonga (za- "C") kunye nophahla kanye ( "K"). Kwakhona, le nto zisenokwahluka ngokohlobo inkangeleko. Kakade ke, kufuneka esisetyenziswe kuphandla sheet ezifulelwe. Ngokumalunga iprofayili, kule nkalo, kuba khazi ongakhetha inkqubo kophahla "wave" okanye "trapezoid" ukuphakama 25-31 mm ziqhele.

Ebubanzini kangangoko iphepha enkalakahleni uthathwa 0.8 mm. ukhetho 1 mm Ngamanye amaxesha kananjalo uphahla khazi kunye ekhethiweyo. izinto ezinjalo obukhulu ngokuqhelekileyo bafumana ukuba ukuthambekela kophahla ubuncinane kwiphepha profiled ekhethiweyo. Degree, njengoko sibonile, olu khetho i-elinesihlanu anesibhozo. Ngokweesentimitha njengoko ichazwe kwi ukuphakama ephakeme. I ebanzi emngxunyeni, kokukhona uya kuba nani.

Ukuze skate indawo enkulu kakhulu kuyimfuneko ukusebenzisa imiqolo emibini okanye emithathu kweemakhishithi. Nangona kunjalo, uyilo uphahla nangoku awayesoloko ngendlela apha eza kuthi sheathe emgceni. Ngoko ke, xa bekhetha iincwadi kufuneka sinikele ingqalelo kuquka ubude bayo. Amaninzi nazo yokuthengisa sheet zentsimbi kweemitha ezi-6. Ngoko ke, oko kunokwenzeka, kwaye ukuyila uphahla ubalulekile ukuba a ubude enjalo.

Indlela yokubala isixa izinto ezifunekayo kubagubungela uphahla

iprojekthi lephahla kufuneka ke azibandakanyi nje kuphela imizobo kuyo, kodwa uqikelelo zonke iindleko elizayo. Bala inani elifunekayo izinto nophahla ayikho nzima kangaka. Ukuze wenze oku kufuneka nje indawo uphahla lahlulwe kwindawo kwiphepha elinye. Ngelo xesha, Kambe ke, kufuneka ithathele seqela ingqalelo. Inowuthi Uphahla ezizezona zisezantsi isniphu sheet trapezoidal - 8-15 degrees. Kuba ziyangenana kophahla tyaba, njengoko sele kuchaziwe, kuya kuba-20 cm. Oko kukuthi, indawo lilonke iphepha ngalinye kule meko kufuneka athathe kanye-20 cm.

Zuza izinto kufuneka esima encinane. Eneneni, ngexesha obandayo, amanye amaxwebhu ukuze nokuba yonakele. Kukwasebenza kwanjalo kuyo izinto ezongezelelweyo. Oku kuyinyaniso ngakumbi kwimeko apho pitch ubuncinane ekhethiweyo uphahla ebhodi incence. Eyamkelekileyo iparameters (8-15 °) kule meko kubalulekile ukuba bagcine. Kodwa nayiphi na imeko, ezi sheathing kophahla izidanga kancinci inzima ngaphezu epholileyo, kuba xa enza le nkqubo, phakathi kwezinye izinto, kufuneka sisebenze gasket okanye sealant.

ukuze ingqokelela

Ukuqala ukufakelwa sheet profiled babe ungqameko olungezantsi eluphahleni. Umdibaniso lwenziwa kwi izikrufu kunye amatywina ezikhethekileyo. Le yokugqibela ibhalwe ngamaza kwiphepha ukugoba trapezoidal. Ngaphambi kokuba umbandela ngokwayo enyusiweyo lwesakhiwo strip, idreyini, itshimini ngamanzi bese iintlambo isibiyeli ezantsi.

Sami kwiimakhishithi iibhloko kwani. Oko kukuthi, okokuqala ikreyiti kule Ridge jija Iqinisekile kuqala. Kutheni ngokufanayo iphepha yesibini eqhotyoshelweyo. Ukongeza, kuba emileyo izikrufu kowokuqala. Ngokufanayo, iphepha wesithathu imvelaphi inyuselwa khona. yonke Le yunithi uhambelana ngokupheleleyo wophahla yanamathela ngenqindi phantsi.

Ngelo isigaba sokugqibela ngombala kophahla zifakwa Ridge, idake intili, iirholithi isiphelo nogwali ifaskoti. Ukuba kuyimfuneko, umise stop ikhephu.

Ezinye iingcebiso kokufaka

Nyusa sheet iprofayile kwi imfuneko uphahla elinye. Ivela xa ngezikhonkwane kokujikeleza pine yesinyithi kufuneka ngoko nangoko atshayele ibrashi. Kungenjalo, umaleko Polymer ukuba yonakele, ekhokelela ukuncitshiswa ebomini wenkonzo eluphahleni. Ukuhamba phezu kophahla ngexesha lomsebenzi kufuneka kwi izihlangu kunye amathe ethambileyo. Ukuba uhlohla Polymer umaleko trapezoidal sheet iya kuqhubeka phina, iindawo ezonakeleyo kufuneka ngoko nangoko aphathe inamehlo okhethekileyo. Ubuncinane ithambeka of enamathela a self-inkxaso kuhanjwa - degrees-8. Kuba uphahla flat ngentla ukuthobela nezi zindululo kubaluleke ngokukhethekileyo. Ngapha koko, kunye ethambekeni oluncinane uphahla liya kuba ngaphezu njengomthwalo kakhulu.

Qhoboshela sheathing amaxwebhu ngokusebenzisa kuphela ngezikhonkwane ezizodwa kunye gasket. Sebenzisa rivet okanye izikhonkwane le njongo ngeke. Ngezikhonkwane kufuneka ziqinisiwe hayi uyadana.

endaweni yesiphelo

Ngoko ke, siza kufumana oko inowuthi kophahla ubuncinane sheet trapezoidal. Izibalo ekuqulunqweni yophahla enjalo kwenziwa kakuhle ngenxa ubude, ububanzi sheet. Kulo mzekelo, impahla akanyanzelekanga ukuba kunqunyulwa. Kwaye njalo, ekugqibeleni iya kuba linxuwa ngaphantsi, kwaye ngenene wophahla ufumane kakhulu ngakumbi ethembekileyo ixesha elide.
