纖維增強水泥板的安裝與固定

Thu,17 Jan 2019   15:16:31

(1)根據設計圖紙和實際施工情況,對板材進行切割和開孔,必要時現場作倒角,纖維增強水泥板的兩長邊都已作好倒角處理,但當墻體高于2440mm時,纖維增強水泥板水平接縫的短邊必須現場倒角,以便更好地處理接縫。

(2)在纖維增強水泥板面上彈線并標出自攻螺釘固定點,同時預鉆凹孔(孔徑比自攻螺釘頭大1mm~2mm,孔深1mm~2mm)。自攻螺釘距板邊15mm,距板角50mm,自攻螺釘間距200mm~250mm。
(3)隔墻鋪板時,一般采用縱向鋪設,即板的長邊固定于豎龍骨上;板材對接時要自然靠近,不能強壓就位;墻體兩面的接縫應相互錯開,不能落在同一根龍骨上。

(4)固定纖維增強水泥板時,板與龍骨應作預鉆孔,孔徑比自攻螺釘直徑小1mm,纖維增強水泥板用自攻螺釘固定,固定時應從板的中間部向周邊固定,所有螺釘頭均應沉入板面1mm。

(5)安裝門窗周圍板時,板縫不能落在與地面水平和垂直框龍骨上,以避免門窗的經常開關產生振動而造成板縫開裂。
