多层和高层建筑中的现浇混凝土框架越来越多,在钢筋混凝土柱边立木门樘,一般做法是设预埋件或预埋螺栓,来固定木门樘。近来随着钢模板的广泛使用,在柱上预埋螺栓比较困难,钢模板上钻洞的代价也大。我单位施工的工程,系一多层现浇钢筋混凝土框架结构,在靠现浇混凝土柱的边上需立 The number of cast-in-place concrete frames in multi-storey and high-rise buildings is increasing. In the reinforced concrete column side, the wooden door sill is set. Generally, embedded or pre-embedded bolts are installed to fix the wooden sill. Recently, with the widespread use of steel formwork, it has been difficult to embed the bolts on the columns, and the cost of drilling holes in the steel formwork has also been great. The construction project of our company is a multi-layered cast-in-site reinforced concrete frame structure that is required to stand on the edge of a cast-in-place concrete column.
