摘要
为了考察不同轻集料混凝土小型空心砌块的孔洞形状、孔壁的厚度、孔洞的排数以及孔洞的排列方式等因素对其热阻的影响,利用"实时标定"检测方法对不同砌块组成的墙体的热阻进行测试。结果表明,以上因素中对热阻影响最大的是孔洞的排数,增加孔洞排数对于热阻的提高比较明显;孔洞应以贯通式矩形为佳,减薄孔壁也能有效地增大热阻。
In order to investigate the influence of the shape, the wall thickness, the rows and the arrangement of the holes on the thermal resistance of different small hollow blocks of lightweight aggregate concrete, the "real time settling" method is applied in this paper to measure the thermal resistance for different blocks. It is concluded that the most important influence on the thermal resistance of the above factors is that the rows of holes with the shape of a through rectangle, and the reduction of the wall thickness of the hole can also effectively increase the thermal resistance.
