The invention relates to a building vertical wall template block composed of a row of blocks. The building has at least one slab or floor, its periphery is extended with a chain and / or at least one opening, and its lower part forms a windowsill at the upper end of the railing, The block has at least one base (1) which is substantially parallel to the hexahedron and comprises a top surface (4) and a bottom surface (3),The two sides (5) are parallel,And two front walls and a rear wall (6),They are parallel or nearly parallel to each other, and a vertical plane (2) is substantially parallel to any surface of the base (1) and is intended to extend along the periphery of the floor or cork;The prominent feature of the template block is that the base (1) has a vertical honeycomb (9), which leads to the top surface (4), and a weft yarn (16) is placed on it, and the grid size is sufficient to prevent concrete from flowing into the honeycomb (9).Figure 1
