φ25m浅圆仓锥形顶施工

The conicnode construction of φ25m shallow barn

为解决中央直属粮库筒仓直径大而使施工难度大的难题 ,根据工程特点 ,结合工程实际情况 ,通过综合分析和探讨 ,决定了锥壳模板的铺设方式和脚手架的搭设方式 ;对锥顶角为度 3 0° ,其钢筋绑扎严格按制点的五点要点执行 ;锥顶混凝土采用螺旋状环壳体对称浇注 ,浇筑宽度及速度均为最佳。以此方法施工 ,使该工程质量一次达优。

In order to solve the problem of silo diameter of g rain depot directly under central management is large and the construction is difficulty, according to engineering characteristics, combining engineering practice, through compreh ensive analysis and discussion, the put-out manners of cone cover formwork and s caffold are decided. To conic node, the conic angle is 30 degree, its concrete i ron bandage must be implemented strictly according to the five points. Concrete on the conic node is bored symmetrically by spiral ring shell, the breadth and s peed are best. Construction by this mean makes engineering quality achieve excel lent once.
