采用49厘米的KP—1空心砖(或多孔砖)砌筑的墙体.热工性能远不能达到哈尔滨地区建筑节能达标的要求。本研究为北方寒冷地区提供一种新型多孔砖,实现49厘米的墙体即可达到节能30～50%的要求。多孔砖的保温性能主要取决于多孔砖的孔洞率、孔形及孔的排列形式。为进一步提高多孔砖的保温性,需要减小多孔砖的孔壁的厚度.增大孔洞率;或对孔形及孔的排列进行优化设计,尽可能增加热传导路线。但产
The wall made of 49-cm KP-1 hollow bricks (or perforated bricks) can hardly meet the requirements for building energy-saving standards in Harbin. This study provides a new type of porous brick for cold regions in the north. A 49 cm wall can achieve a 30 to 50% energy saving requirement. The thermal insulation performance of porous bricks mainly depends on the porosity of the perforated bricks, the shape of the holes and the arrangement of the holes. In order to further improve the insulation of the perforated brick, it is necessary to reduce the thickness of the hole wall of the perforated brick, increase the hole rate, or optimize the arrangement of holes and holes to increase the heat conduction route as much as possible.
