为了满足建筑的热工性能及减轻建筑自重,创造了一眠一斗一丁及二眠一斗一丁的三七空斗墙砌筑法(见图示),此法基本原理是利用新式空斗墙的丁砖将眠砖及斗砖牢固联成整体,其热工性能与370实体墙类同,如在其空斗中填上炉渣之类的松散物,则其热工性能还优于一般370墙,而用砖量及自重却同一般240实体墙,且上丁砖时还可用半截砖,故在经济上具有明显的优越性。这种三七空 In order to meet the thermal performance of the building and reduce the weight of the building, it created a three-seven empty bucket wall masonry method (see illustration) that has been used for sleeping, fighting, sleeping and fighting. The basic principle of this method is to use the new style of empty space. The builing bricks of the bucket wall integrate the bricks of sleep and the bucket bricks together. Its thermal performance is similar to that of the 370 solid walls. If the bucket is filled with loose materials such as slag, its thermal performance is better than Generally 370 walls, but with the amount of bricks and self-weight but with the general 240 physical walls, and when the Dingzhu brick can also be used when half, so it has obvious economic advantages. This three-seven empty
