針對混凝土砌塊墻體開裂你有什么預防措施

關鍵詞:預防混凝土砌塊墻體開裂措施
  該砌塊是一種新的建筑原料,并且被廣泛使用在很多方面,它具有保溫隔熱、親質多孔、環(huán)保等優(yōu)點,但是由于很多原因會造成墻體開裂,這是值得我們去注意的,并且在施工之前要做好一切措施,這樣才能保證質量。

  預防混領土砌塊墻體開裂措施:

  1、常州中晶自保溫墻體材料有限公司介紹剪力墻凸出墻面者,抹灰先抹墻面,待墻面抹灰層干燥后再抹混凝土表面,并使混凝土表面的抹灰層壓在墻體的抹灰層上,使連接處的收縮裂縫被混凝土面后抹的抹灰層所覆蓋。

  2、對剪力墻的填充墻,當墻體砌至^后一層時(即梁底),用輔助實心小砌塊(或實心標準磚)斜砌的方法砌筑,使砌體與梁底緊密接觸。砌筑砂漿應飽滿。

  3、預防混領土砌塊墻體開裂措施:因為結構采用大模板施工,混凝土表面較光滑,在粉刷前,采用混凝土界面劑以增強粉刷層和基層的粘結效果。外墻面層粉刷時,在砂漿中可摻適量丹強絲纖維,以增強外墻的抗裂能力。

  4、設備槽孔應預留,因漏埋或未預留時,采用切割機開槽,嚴禁硬鑿,損壞墻體,如有松動必須處理補強。落地砂漿及時清除,以免與地面粘結,影響下道工序施工。砌塊在裝運過程,應輕裝輕放,計算好各房間的用量,碼放整齊。

  5、應嚴格控制新墻材的含水率和含水深度。使用時,應提前1到2天澆水濕潤,不得隨澆隨砌。雨期施工,新墻材不應露天貼地堆放,并應有可靠的防雨淋措施。被雨水淋濕的新墻材不得立即砌筑。
