为了提供用于室再生加热炉，特别是玻璃熔化炉，尽管粘附的稳定结构，以用于热存储容量的最佳利用的低通道壁厚度耐火砖制横卧光栅贴片，是光栅贴片（3,3“）由相邻和重叠， 耐火材料，棱柱形空心砖（4,6），其具有在它们的纵向轴线的水平布置的矩形，最好是正方形内并构造Außenquerscnnitt。

In order to provide for a lying mesh stocking of firebricks for chambers regeneratively heated furnaces, especially glass melting furnaces, a stable structure, although complying with a low channel wall thickness, for optimal utilization of the heat storage capacity, is the mesh stocking (3,3 ') of adjacent and superimposed, refractory, prismatic hollow bricks (4, 6) with a rectangular, preferably constructed of square inner and outer cross section in a horizontal arrangement of their longitudinal axes.
