Ke Hobane'ng ha Li-Screws tse Tloaelehileng tsa Drywall li hloleha ho Likopo tsa Layer-to-Layer

Bongata ba li-installer li fihlella li-screw tse tloaelehileng tsa khoele e omeletseng—#6 x 1¼’ kapa #8 x 1⅝’—ntle le ho hlahloba hore na likhoele tseo li kopanya *likarolo tse peli* ka katleho. Ka ts'ebetso, re fumane mekhoa e meraro e sa fetoheng ea ho hloleha:

• Ho kena ka tlase: Sekurufu se ema letlapeng la pele, se siea lefela letotong la bobeli—haholo-holo ka ⅝’ Mofuta oa X o teteaneng kapa liphanele tse hahelletsoeng ka mollo.
• Ho kenella ka ho fetelletseng: Ntlheng e phunyeletsa ka morao ea leqephe la bobeli, e etsa hore ho be le dimple eo telegraph e kenang ka pente 'me e senya botšepehi ba litekanyetso tsa mollo.
• Ho hula ka ntle nakong ea libaesekele tse futhumetseng: Li-screws tse tloaelehileng ha li na geometry ea khoele ho hanela micro-motsamao pakeng tsa maqephe ha mocheso o ntse o fetoha. Re lekanya ho fihla ho 0.18 mm lateral creep ka matsatsi a 90 libakeng tsa mabenkele tse se nang maemo.

Motso oa sesosa? Li-screws tse tloaelehileng li entsoe bakeng sa li-drywall-to-wood kapa li-drywall-to-metal stud-eseng li-inter-sheet bonding. Likhoele tsa tsona tse mabifi tse mahoashe lia khaola ho e-na le ho notlela; malebela a bona a sa hlakang ha a ikamahanye le li-substrates tse lehiloeng.

Lintlha tse tharo tsa tekheniki tseo e leng tsa bohlokoa

Kamora ho etsa liteko tsa li-screw tse 27 libakeng tse 14 tsa mesebetsi - ho tloha ho litokiso tsa bolulo ho isa ho liphasejeng tsa sepetlele - re ile ra khetha se arolang se ka tšeptjoang. drywall ho omisa scrywall ho tsoa likhakanyong tse nang le tšepo:

1. Sekhahla le botebo ba khoele: Optimal ke likhoele tse 24–28 ka inch (TPI), e nang le likhoele tse tebileng tse fetisang bonyane 75% ea bolelele ba shank. Likokoana-hloko tse nang le likhoele tse tepeletseng kapa mekhoa e sa tebang ea "ho itšeha" e ile ea lahleheloa ke 40% ho feta ea ho hula liteko litekong tse peli tsa ho kuta.
2. Keletso ea geometry: Nalete e fatše e nepahetseng—eseng chisel kapa gimlet tip—e iphumana e le litsi tsa gypsum tse pakiloeng ntle le ho cheka pele. Re netefalitse phokotso ena e fosahetseng ka 83% likopanong tse kobehileng tsa soffit.
