国家残疾人冰上运动比赛训练馆静压箱工程施工技术

Construction Technology of Static Pressure Box Project of National Disabled Ice Sports Competition Training Hall

国家残疾人冰上运动比赛馆建设项目是2022冬奥会的重要配套项目,本工程致力于建造国际一流的无障碍设施样板工程,为残疾人提供方便实用的体育运动场所。观众区域是本场馆的人员集中区域,观众区域空调形式为全空气系统,在每个座位的下部设置送风口,送风口与送风管道连接,通过组合式空调机组集中送风。但原设计方案静压箱为钢筋混凝土现浇结构,无法进行施工。同时,观众区域阶梯座椅下方空间狭小、形状不一,传统的金属风管及保温施工难度很大,且会给阶梯座椅下方的吊顶装饰、给排水管线、电气桥架及相关设备的吊装造成难度。

The construction project of the National Ice Sports Hall for the disabled is an important supporting project for the 2022 Winter Olympics.The project is committed to building a world-class model project of barrier-free facilities and providing convenient and practical sports venues for the disabled.The audience area is the crowded area of the venue.The air-conditioning in the audience area is a full-air system.The air outlet is set at lower part of each seat,and the air outlet is connected with the air duct,and the air is supplied through the combined air conditioning unit.However,the original design plan of the static pressure box is a reinforced concrete castin-place structure,which cannot be constructed.At the same time,the space under the ladder seats in the audience area is narrow and different in shape.Traditional metal ducts and thermal insulation construction are very difficult,and will bring difficulties caused by ceiling decoration,water supply and drainage pipelines,electrical bridges and related equipment to be lifted under the ladder seats.
