摘要
建筑幕墙密封构造具备适应自然环境条件变化的能力,对有效稳定地发挥其密封功能,保障整体建筑节能水平,具有重要的意义。本文以冬奥场馆国家会议中心二期“群鸟”幕墙工程为研究对象,采用实体模型试验研究方法,选取两个典型密封构造部位,对标准状态下、抗风压试验后、层间变形试验后及热循环试验后四种工况下的空气渗透量进行测试,并对同一密封构造在不同工况、不同密封构造在同一工况下的密封性能进行比较。通过分析,本文得出“群鸟”幕墙工程南北侧密封构造适应自然环境变化能力优于东侧幕墙密封构造的结论。该试验研究结果,为建筑幕墙密封构造的合理设计提供了研究思路,也为进一步完善建筑幕墙密封性能测试方法积累了经验。
For the sealing structure of building curtain wall, its ability to adapt to the change of nature environment conditions, is of great significance to play its sealing function effectively and stably, and consequently guarantee the energy saving level of the entire building. By taking the “Birds” curtian wall of the the National Conference Center II which is one of the Winter Olympic venues as the research object, two typical sealing structures under four working conditions, including the standard states and the state after the test of resistance to wind pressure, the interlayer deformation, and the thermal cycling, are chosen for measuring the air permeability. The sealing performance of the same sealing structure in different working conditions and different sealing structures in the same working conditions are compared. Through analysis, this paper draws a conclusion that the sealing structure of the south and north side of the “Birds” curtain wall project is better thant the sealing structure of the east side. The experimental study provide a research ideas for the rational design of the sealing stucture of the building curtain wall, and also accumulate experience for the further improvement of the sealing performance test method of the building curtain wall.
