Description
したがって、図１３の特にｂ）からｅ）に示すように、バンドもしくは層もしくは重なりＳＴ内に垂直もしくは鉛直に、かつバンドＳＴの外側に水平もしくは平らに、スリットを形成することができる。したがって特に、ウェブによって結合された、通過部を有する２つの幅狭の、もしくは薄い建造物部分もしくは壁ＢＷＴを形成することができ、それによって後に間隙に緩衝材を充填し、あるいは導管（導線）設備を収容することができる。特に図１３ｃ）、ｄ）及びｅ）のバンド横断面４は、流出方向ｘに／それに抗して、特にこの順序で、配置することができる。したがって付加的又は代替的に、媒体通路を生じさせるために、開放したバンド横断面４を形成することができる。特に図１３ａ）、ｂ）、ｃ）及びｂ）のバンド横断面４を、特にこの順序において、流出方向ｘに／それに抗して配置することができる。さらに付加的又は代替的に、最大の開放幅ＢＯに完全にはわたらない、バンドＳＴ上に、少なくとも１つの他のバンドＳＴの載置を可能にするために、たとえば格子のような、支持構造を配置することができ、かつ／又は配置されている。これが、柔らかい建造材料が空間、特に中空空間内へ、下方に沈下するのを回避することを、可能にする。Thus, slits can be formed vertically or vertically within the band or layer or stack ST and horizontally or flat outside the band ST, as shown in FIG. 13, particularly b) to e). Thus, in particular, it is possible to form two narrow or thin building parts or walls BWT with passages connected by a web, by which the gap can be subsequently filled with cushioning or conduits (lines). equipment can be accommodated. In particular the band cross-sections 4 of FIGS. 13c), d) and e) can be arranged in/against the outflow direction x, in particular in this order. Additionally or alternatively, therefore, an open band cross-section 4 can be formed in order to create a medium passage. In particular the band cross-sections 4 of FIGS. 13a), b), c) and b) can be arranged in/against the outflow direction x, in particular in this order. Additionally or alternatively, a support structure, for example a grid, to allow the placement of at least one other band ST on the band ST which does not completely span the maximum open width BO can be and/or are located. This makes it possible to avoid the soft building material sinking downwards into the space, in particular into the hollow space.
