Txoj kev qhuav screed tau siv ntev. Nws tau dhau los ua neeg nyiam heev ntawm cov kws tshaj lij thiab cov neeg ua haujlwm pib ua haujlwm thaum muaj cov txheej txheem tshwj xeeb ntawm cov khoom siv rau ntau hom kev ua haujlwm.
Lub tuam txhab "Knauf" tau txais txiaj ntsig dav ntawm cov neeg tsim khoom. Cov ntsiab lus hauv pem teb ntawm cov chaw tsim khoom no yog ib feem tseem ceeb ntawm cov txheej txheem rau flooring. Lawv siv ua cov txheej txheem ntawm leveling thiab npaj cov nto rau txheej technology heev.
YGypsum board
GVL cov ntaub ntawv (gypsum-fiber sheets), uas ua rau cov khoom hauv pem teb (Knauf), tau faib zoo hauv kev tsim kho kev lag luam. Cellulose fibers los ntawm cov ntoo khib nyiab los yog cov ntawv pov tseg yog fluffed nyob rau hauv ib txoj kev tshwj xeeb thiab tov nrog ib tug gypsum binder. Lub resulting loj yog wetted thiab nias rau hauv daim ntawv. Tom qab ziab, sib tsoo thiab txiav,phaj nrog lub thickness ntawm 10-12 hli. Yog li ntawd cov gypsum fiber tsis stain tes thiab khaub ncaws, nws yog impregnated nrog ib tug anti-chalking compound. Qhov zoo ntawm GVL yog ib puag ncig kev phooj ywg, hluav taws kub, muaj peev xwm nqus dej ntau dhau, muaj peev xwm kub thiab suab rwb thaiv tsev. Yog tias koj siv cov dej-repellent additives, GVL tau txais cov dej noo tsis kam.
Qhov tsis zoo ntawm GVL yog nws qhov hnyav, brittleness thaum thauj thiab ua haujlwm. Yog li ntawd, nws yooj yim dua los siv me-hom GVL. "Knauf" ua cov khoom hauv pem teb los ntawm cov nplooj ntawv zoo li no.
Kev piav qhia hauv pem teb
Vaj huam sib luag rau prefabricated puag - Knauf "Superpol" pem teb caij - muaj ob daim GVL 10 hli tuab, 1200x600 loj. Nyob rau hauv lub Hoobkas, lawv yog glued ua ke nrog ib tug hloov ntawm 50 mm nyob rau hauv ob txoj kev. Raws li qhov tshwm sim ntawm kev hloov pauv, ib qho quav yog tsim rau kev sib sau cov panels rau hauv ib lub lawj. Los ntawm qhov quav no, cov ntsiab lus tau muab khi ua ke thiab ntsia hlau nrog tus kheej tapping screws.
Cov kab ntev ntawm cov ntawv tuaj yeem ncaj thiab inclined - quav, kawg - ncaj.
Nyob screed technology
Cov hauv pem teb uas lub hauv paus prefabricated yog mounted tuaj yeem yog pob zeb (monolithic lossis prefabricated los ntawm slabs) lossis ntoo (nrog board lossis ntawv flooring). Nyob rau hauv txhua rooj plaub, nws yog tsim nyog los npaj ib tug hydro- thiab vapor barrier los ntawm nteg ib tug PVC zaj duab xis los yog ib tug yob cov ntaub ntawv uas xav tau. Cov strips yog pw nrog ib qho sib tshooj ntawm 200-250 mm thiab sib tshooj ntawm phab ntsa. Cov txheej no yuav tiv thaiv ob qho tib si los ntawm kev xau los ntawm sab saud thiab nkag mus ntawm cov dej noo los ntawm lub qab nthab.
Cov qauv kaw -Sab nraud thiab sab hauv phab ntsa raug cais los ntawm lub neej yav tom ntej "pie" nrog lub suab-absorbing ncoo: ib daim kab xev ua los ntawm foamed polymer cov ntaub ntawv yog nteg nyob ib ncig ntawm lub perimeter.
Ib txheej ntawm rov qab yog siv rau zaj duab xis, qhov tsawg kawg nkaus thickness yog 20 hli. Cov txheej txheem no ua ib qho chaw tiaj tus rau kev tso cov panels thiab ua haujlwm ntawm cov cua sov thiab lub suab rwb thaiv tsev. Rau backfilling, txhua yam khoom siv yog siv, muaj cov granules ntawm kwv yees li qhov loj me, nrog ib feem ntawm 3-5 hli, tsis muaj plua plav thiab av. Expanded av nplaum xuab zeb muaj qhov zoo tshaj plaws. Rau lub hauv paus ntawm nws, tshwj xeeb tshaj yog npaj filling rau qhuav screeds yog npaj: Compevit, Keraflur, thiab lwm yam.
Cov khoom siv rov qab yog qib raws li qib hauv pem teb tau txiav txim siab los ntawm qib laser lossis qib hydraulic. Rau qhov no, nws yog qhov yooj yim los siv cov cuab yeej tshwj xeeb los ntawm Knauf: ib txheej ntawm cov lus qhia ib ntus thiab txoj cai. Ntau zaus, qhov profile rau kev txhim kho GVL yog siv los ua beacons.
Pro Tip
Cov kws tshaj lij qhia siv beacons tsuas yog txhawm rau txhim kho qhov rov qab thiab tsis tso GVL (KNAUF) cov khoom hauv pem teb rau lawv. Cov txheej ntawm cov khoom siv ntau yuav shrinkage thiab compact thaum lub sij hawm, cov panels yuav pib so ntawm cov hlau, uas yuav ua rau lub suab nrov thiab txo thermal rwb thaiv tsev ntawm prefabricated pem teb qauv. Yog li ntawd, beacons yuav tsum tau muab tshem tawm.
Lub fragility ntawm cov qauv hauv pem teb yam tsis muaj kev lag luam li niaj zaus pom meej. Ua tib zoo leveled backfill thiab qhov chaw zoo hauv pem teb tsim los ntawm Knauf muaj lub peev xwm thauj khoom siab heev.
Lawv tso rauib tug leveled nto nrog ib tug so ntawm kab ntawm tsawg kawg yog 250 mm. Txhawm rau sib sau ua ke hauv pem teb, cov kua nplaum tshwj xeeb yog siv rau lub folds ntawm cov panels raws li cov lus qhia. Tom qab ntawd txhua lub hauv paus ntawm Knauf hauv pem teb yog txuas nrog tus kheej tapping screws 19 mm ntev, uas yog screwed nyob rau hauv nruj nreem vertically, tog taub hau ntawm tus kheej-tapping screws.
Cov theem kawg ntawm lub hauv paus ntaus ntawv yuav muab tso rau hauv cov ntsia hlau recessed thiab seams ntawm GVL panels thiab priming saum npoo nrog ib tug hardening compound. Tom qab ntawd, lub hauv paus ntawm hauv pem teb yog npaj rau cladding nrog txhua txheej txheej - ob qho tib si dov thiab daim.
Kev xaiv yog
Txoj kev npaj hauv pem teb no muaj ntau yam zoo. Cov no yog kev ceev, yooj yim, kev ywj pheej ntawm qhov kub thiab txias, nce suab nrov thiab rwb thaiv tsev kub. Qhuav screed yog txheej txheem kev tsim kho thiab kev paub zoo heev. Tsis xav tias nws ntseeg tias txawm tus neeg uas tsis muaj kev paub dhau los tuaj yeem ua cov plag tsev zoo li no.
txhawm rau txhim kho cov plag tsev prefabricated, lwm yam khoom siv hauv vaj huam sib luag kuj tseem siv: gypsum boards, chipboard, zoo tib yam thiab noo noo-resistant plywood. Tab sis tsuas yog cov khoom hauv pem teb uas tsim los ntawm Knauf feem ntau sib haum nrog cov thev naus laus zis no, txhim kho nws cov txiaj ntsig zoo.
