<p>A heat-insulated hollow block or brick, presenting a shape of cube, comprises six surfaces, i.e. a bottom horizontal bricklaying surface (1), a top horizontal bricklaying surface (2), a front vertical bricklaying surface (3), a back vertical bricklaying surface (4), a left vertical non-bricklaying surface (5) and a right vertical non-bricklaying surface (6), provided with at least one groove serving as a hollow portion. The grooves include a blind groove (7), which is communicated with the bottom horizontal bricklaying surface (2) and one of vertical bricklaying surfaces (3,4), and/or a through groove (8), which is communicated with two horizontal bricklaying surfaces (1,2) and one of vertical bricklaying surfaces (3,4), with a width of an opening on the top horizontal bricklaying surface (2) less than 5 mm and a proportion between the width of the opening on the top horizontal bricklaying surface (2) and that of a vertically corresponding opening on the bottom horizontal bricklaying surface (1) less than 1/2.</p> |
