會問這個問題是因為通常灌漿都是從樓板開始灌
混凝土從樓板面落入柱底及牆底,我覺得太高了
最低高度也是樑底,還是太高,(假設樓高3.3米)
柱底牆底經常灌不好,窗台下方有時也會沒灌飽
雖然有用震動,但是因為長度限制,只震到上半部
牆體柱體的下半部事實上根本沒震動
我覺得灌漿加水的目的部分就是想解決這個問題
加水加得好像自充填,這樣怎麼灌都飽
是不是可以從窗台開始灌,窗台下緣先不封
從窗台下方兩側開始灌漿,溢流至兩側牆體或柱體下方
配合震動棒,直到灌漿高度到了窗台下方後,窗台再封模
之後再從樓板繼續灌
我想此時窗台封模應該沒有太大困難,也確保窗台下一定飽
窗台下方也不用留觀察口
沒有窗台的地方,沒辦法只好做喇叭口
或者先進有更好的灌漿方式?
另外震動棒的使用也有問題
常見操作的師傅都是點到即止,東點一下,西點一下
但都很快提起來,幾乎沒有停留時間
這跟震動棒廠商的使用規範不合
應該是垂直降下,定點震動5-10秒,再緩慢垂直提起
每隔45公分左右再重複一次
各家規範略有差異但都差不多,還不致粒料分離
其實震動棒對於灌飽,是一項重要的利器
正確使用應該可以使低灘度混凝土也能輕鬆就灌得很飽
不會有什麼低灘度混凝土工作性不佳這種問題
工作性不佳是因為營造不懂利用震動棒
