  蒸壓粉煤灰磚的砌筑工藝流程

  蒸壓粉煤灰磚的砌筑工藝流程是作業準備→拌制砂漿→排磚摞底→砌筑→驗評。

  砌筑前按實地尺寸和砌塊規格尺寸進行排列擺塊,不夠整塊的可以鋸裁成需要的尺寸,但不得小于砌塊長度的1/3。蒸壓粉煤灰磚排列上、下皮應錯縫搭接,搭接長度一般為1/2,不得小于砌塊與高度的1/3。

蒸壓粉煤灰磚

  砌體墻頂與樓板或梁應加上一層斜砌,或有可靠拉結,上部拉結一般間距1.5m,留預2Φ6拉筋,伸入墻內不少于500㎜。當墻高大于3m時,按設計要求加設水平鋼筋砼帶,若無設計要求,一般每高1.5m,加設2Φ6或3Φ6鋼筋帶,保證蒸壓粉煤灰磚墻體的穩定性。

  砌筑時,按排好的尺寸,先砌兩端的頭一皮,然后掛線砌墻身,鋪一塊磚長的砂漿砌一塊,擠揉密實,“上跟線,下對棱,左右相鄰要對平”。蒸壓粉煤灰磚砌體水平灰縫厚度一般為15㎜,垂直豎縫寬度為20㎜。豎縫大于30㎜,應用C20細石混凝土灌實。每砌一皮校正后,用砂漿灌豎縫。

  砌塊墻與門框連結:將預制好埋有木磚的砼塊,木磚應提前做好防腐處理,預埋時小頭在外,大頭在內,數量按洞口高度決定。洞口高度在1.2m以內,每邊埋2塊,高度在1-2m,每邊埋3塊,高度2-3m,每邊埋4塊,預埋木磚的部位一般在洞口上下邊四皮磚,中間均勻分布。

  以上便是蒸壓粉煤灰磚的操作工藝簡述,如有加氣磚使用需求,歡迎咨詢洛陽萬基新型墻材有限公司。
