剑阁县高池乡卫生院业务楼 冬季专项施工方案 摘要：剑阁县属于亚热带湿润季风气候,同时受海洋,大陆性气候控制。特点明显,其特征是冬季漫长寒冷,春季干燥多风,夏季炎热多雨,秋季凉爽湿润,春季季短,冬夏季长。 以剑阁历年气象资料看:历年平均气温为 15～16 摄氏度,七月平均气温 29.9 摄氏度,1月平均气温2.3 摄氏度,极端最高气温 36.1摄氏度,极端最低气温-1.1摄氏度。冬季施工期限划分原则:当室外温度连续五天平均低于 5℃,即进入冬季施工,当室外温度连续5天高于5℃即解除冬季施工，拟采用暖棚法进行冬季砼施工。 混凝土的冬期施工,主要是保证混凝土在浇筑时不冻结,能顺利浇筑在模板范围之内时,应进行混凝土的覆盖保温养护。 低温条件下使用的钢筋,施工过程中加强检验,检查;钢筋在运输和加工的过程中防止撞击和刻痕。 采用木板作为模板时,在木模板的区格间填以 50mm 厚保温棉,用胶粘贴在模板上,浇墙体混凝土时,外墙外侧模板应再覆盖一层石棉保温。 加强冬季劳动保护安全工作,冬期要作好防滑,防冻,防煤气中毒等工作。脚手架,上下梯道要采取防滑措施，雪霜天气要及时清扫，大雪后及时检查脚手架,防止空中坠落事故发生。 关键词：冬季施工； 安全； 措施； 预案 JianGeXian kochi township health hospital business building winter special construction scheme Abstract:JianGeXian a subtropical humid monsoon climate, and sea, continental climate control. Characteristics significantly, its characteristic is long and cold winter, dry and windy spring, hot and rainy summer, the autumn cool, humid, the spring season is short, summer long winter. To JianGe historical meteorological data to see: the average temperature of 15 ~ 16 degrees Celsius, July mean temperature 29.9 degrees Celsius, January average temperature of 2.3 degrees Celsius, extreme maximum temperature 36.1 degrees Celsius, extreme minimum temperatures to 1.1 degrees Celsius. Winter construction period division principle: when outdoor temperature for five consecutive days on average less than 5 ℃, namely into the winter construction, when outdoor temperature is higher than 5 ℃ for 5 days or remove winter construction, proposed USES the greenhouses in winter concrete construction. Concrete winter construction, the main is to ensure when pouring concrete does not freeze, smooth casting in the range of template, should be covered with thermal insulation of concrete curing. Low temperature under the condition of using steel, construction process to strengthen inspection, inspection; Steel in the process of transport and processing to prevent bump and notch. Using wood as a template, between the area of wood template to fill in a 50 mm thick insulation
