亚运会丰台体育中心体育场看台为全现浇钢筋混凝土结构。轴线用50mm宽变形缝分割成20段。看台最多处55阶,最少处10阶,每阶平面均呈圆弧形,设32个入口。看台下设有室内体育用房、技术用房、办公用房、客房及其它用房,最高处有4层。看台既是地面又是屋面,防水面层的施工质量直接影响使用效果。为确保工程质量,杜绝渗漏,经与设计单位协商决定,直接在看台基层上抹防水砂浆,并采取了将看台表面做出一定坡度和将看台阴阳角做成圆弧的方法,实现以排为主、排防结合的防水设想。工程完成后,经过两个雨季的考验,3万m~2看台未发现渗漏。
The stadium of the Asian Games Fengtai Sports Center Stadium is a fully cast reinforced concrete structure. The axis is divided into 20 segments with a 50mm wide deformation joint. The stand is at most 55 steps and at least 10 steps. Each step has an arc shape with 32 entrances. There are indoor sports rooms, technical rooms, office rooms, rooms and other rooms under the grandstand. The highest floor has 4 floors. The stands are both the ground and the roof. The construction quality of the waterproof surface layer directly affects the use effect. In order to ensure the quality of the project and eliminate leaks, it was determined through consultation with the design agency that the waterproof mortar was directly applied to the base of the stands, and a method was adopted to make the slope of the stands and the yin and yang corners of the stands into circular arcs, and to achieve Based on the combination of waterproof, waterproof and anticipation. After the completion of the project, after two rainy seasons, no leakage was found in the 30,000m2 stand.
