我认为确定中型砌块规格的原则应该是:规格种类要较少,通用性要强,局部允许镶砖处理,不搞排列图,砌块的平均长度要大,可以提高吊装效率。规格划分得恰当,适应性就强,这样没有排列图也能施工,只需对主规格尺寸和错缝搭接长度等作出规定即可。若吊装时按排列图对号入座大大影响吊装效率。当不按排列图 I believe that the principle for determining the specifications of medium-sized blocks should be: fewer types of specifications, greater versatility, and partial allowable bricks to be tiled, and no arrangement of maps, the average length of blocks should be large, and lifting efficiency can be improved. The specifications are well-divided and the adaptability is strong, so that construction can be carried out without arranging the drawings. It is only necessary to make provisions for the size of the main specifications and the lap length of the staggered joints. If the lifting of the installation according to the arrangement of the number marking the seat greatly affects the lifting efficiency. When not according to the arrangement diagram
