摘要:
对被动式低能耗建筑墙体内部热工性能进行实测,并研究其墙体构造设计的合理性,能够为低能耗墙体的设计优化提供支持。文章以山东建筑大学教学实验综合楼为例,实测了外墙内部不同位置空腔的温湿度并分析其变化规律,研究了其热工性能及墙体构造的合理性。结果表明:墙体内部空腔的空气温湿度实测数据,能够用于表征空腔位置固体温湿度状况;在保温绝热、内部排湿、外壁面防水3个方面,200 mm厚聚苯板外保温薄抹灰外墙构造做法能满足被动式低能耗外墙设计要求,而15 mm厚水泥砂浆内壁面可能无法有效阻止室内湿热空气的渗透;一年内墙体内部含湿量平均降低了17.5%,5 mm厚抗裂砂浆和真石漆涂料组合的外壁面不能完全阻止雨水的渗入,但渗入雨水在短时间内会迅速排出。
Abstract:
Measuring the actual thermal conditions inside the walls and studying the rationality of wall structure design of Passive House can provide theoretical support for the optimal design of low-energy walls. Taking a teaching and laboratory building in Shandong Jianzhu University as an example, the variance of temperature and humidity inside the wall is measured and analyzed, the thermal performance and construction rationality is studied. The results show that the measured data of air temperature and humidity can be used to characterize the temperature and humidity of the cavity. The construction design of the 200 mm thick polystyrene board external insulation and thin plastering external wall meets the requirements of the following three aspects: thermal insulation, internal moisture discharge and waterproofing of the external wall surface. However, in the gas barrier aspect, the inner wall surface of the cement mortar with a thickness of 15 mm may not effectively prevent the penetration of indoor humid air. The internal moisture content of the wall decreased by an average of 17.5% throughout the year. The combination of 5 mm thick crack-resistant mortar and real stone paint on the surface of the outer wall cannot completely prevent the penetration of rainwater, but the penetrated rainwater will be discharged quickly in a short time.
