摘要
禹州电厂一期主厂房柱、梁、板等构件均采用清水混凝土施工工艺。梁、柱模板采用拼装大块钢模板表面粘贴PVC板 ;现浇板采用20mm厚九合板表面粘贴PVC板工艺 ,混凝土搅拌时严格控制水灰比和坍落度 ,分层振捣均匀、密实 ,以保证清水混凝土构件色泽一致 ,平整美观 。
As-cast-finish concrete technology was adopted in the works of columns, beams and floor slabs of main plant of Yu Zhou power plant phase 1.Huge spliced steel forms stuck with PVC board were used for concrete pouring of beams and columns.Slabs were poured with forms of 20 mm nine-ply board covered with PVC board.When mixing concrete, mixing ratio and slump were controlled strictly,at the same time the concrete were well vibrated at different depth so as to ensure a uniform colour of the concrete and a smooth,good looking surface and accurate dimensions as well.
