现浇混凝土柱施工时,应注意一次浇筑高度不超过2米,防止混凝土分层离析。传统做法是截面大的柱子在柱中设置铁串筒浇筑混凝土;截面小并有交叉箍筋的柱子,在柱模侧面开不小于30厘米高洞口,装上斜溜槽分段浇筑混凝土,高度控制不大于2米。用柱模侧面开洞口的办法施工小截面柱子,受洞口尺寸和斜溜槽坡度限制,
In the construction of cast-in-place concrete columns, it should be noted that the height of one-time pouring does not exceed 2 meters to prevent stratification of the concrete. The traditional method is to set a column with a large cross-section of columns in the column to set the concrete; a small cross-section with cross-stabilizing columns, open at the side of the column mold is not less than 30 cm high hole, install the inclined chute subsection pouring concrete, height control Not more than 2 meters. The construction of small cross-section pillars by opening the hole on the side of the pillar mold is limited by the size of the opening and the slope of the inclined chute.
