露天阶梯式体育场看台从使用功能讲,它既属于一个人流密集的楼地面,又是看台下部房间或外廊的防水屋面。因此,要求饰面工程耐磨擦、抗风雨冲刷、不产生裂缝、不渗水和表面平顺光滑等。这类工程过去多采用水泥砂浆抹面兼刚性防水的做法,但因施工处于露天作业,受气候影响大,水泥砂浆强度相对降低,直接影响使用寿命,达不到原设计的要求。采取合理的施工方法,优选材料及改进配合比乃是确保阶梯式体育场看台饰面质量的关键。
The open-air stadium stadium stands out from the use of features, it belongs to a densely populated floor, but also is the waterproof roof of the lower room or veranda of the stands. Therefore, it is required that the facing works be abrasion-resistant, weather-resistant, no cracks, no water leakage, and smooth and smooth surfaces. In the past, cement mortar plastering and rigid waterproofing methods were used in these types of projects. However, because the construction was exposed to open air, the weather was greatly affected by the weather, and the strength of the cement mortar was relatively reduced, which directly affected the service life and could not meet the requirements of the original design. Adopting reasonable construction methods, optimizing materials and improving mix ratios are the key to ensuring the quality of the stands in the stadium.
