To overcome this and other disadvantages of the known Glass building elements is proposed according to the invention for a glass building element of the type mentioned at the outset that at least two opposing longitudinal side areas of the longitudinal sides of at least one abutment surface in relation to the central wall plane associated with the glass component in the single-shell door hinge with further glass components, forming one of the Rectangular shape deviating TJmrissform of the relevant abutment surface are arranged asymmetrically, the visible surfaces are adapted to this asymmetry, and that the abutment surfaces of the Glass building element are directed perpendicular to the central wall plane.

It works by means of this simple technical hatred Even with hollow glass walls, the lower areas of the tree in question can be supplied with more light than with the known glass construction elements, since the cross-section of the light bundle extending through the straight beam path is greater than when light is incident at an angle With all known glass construction elements of this type, »The better Liohtlenken is particularly important when the liohteinfall on the glass wall is significantly steeper than 30 ° in relation to the wall normal due to the small construction distances, for example in narrow streets.

The acoustic properties of a glass wall made from new types of glass building elements are also significantly better than the acoustic properties of the well-known glass walls, as the innovative design of the glass building elements makes it possible » that their Siohtfläohen superordinate geometric structures result in assembly, whereby longer sound waves than was previously possible are still diffusely reflected.

The new types of glass building elements also have an excellent decorative effect, both individually and when assembled. " In particular, in many cases the known from

It is particularly favorable here if the mutually opposite abutment surfaces of the one Rhombus-shaped glass building element on the middle wall plane are inclined in the opposite direction · This can be achieved, among other things, that practically no preferred direction for power-through with inclined light there is »

The visible surfaces of the new type of glass building element are also adapted to the existing XTasynmßtrl © "ev joint surface or joint surfaces" in relation to the plane of the middle wall.

elements are formed from four identical glass building elements 17 existing components 12, the front Siohtf lachen 18 each have a convex curvature in the form of a uniform pyramid 23 square base, whose base lines are diagonal lines 22 of the individual glass building elements 17. The pyramidal bulge 23 extends over the entire height and width of the component in question »In Pigo 3 a total of four such components 12 are shown, which are of equal thickness, which is achieved by the fact that the pyramidal concave located on the rear visible surface 19 of the component Curve 25 is the negative shape of the pyramidal curvature located on the front visible surface.

It can be seen that, in spite of the use of basically identical glass components, here only because of their angular offset Arrangement can be achieved that the individual component 12 formed from them has a superordinate geometric structure each of its visible surfaces has. This is achieved here by the fact that all edge lines, such as 26, of the individual pyramidal bulge joint lines between the visible surfaces, like 10, of neighboring glass components are «. As a result, among other things, the joint lines that occur with the known glass blocks have a disruptive effect, effectively incorporated into the surface structure of the relevant viewing area and thus stripped of their disturbing character. Also through the in a plane perpendicular to the central wall plane subsequent positioning of a number of ropes in the joint areas, as 15, 16 (Pig. 1), except for the improvement of the Xiohtdurohganges The static properties also apply to inclined light this glass wall improved "

The glass construction iron shown in FIGS. 5 and 6 differs from that shown in Figs Glass construction element in that the two flat rope surfaces, such as 20 *, 21 », of each visible surface 10, 11 by a diagonal line parallel to the plane of the wall, such as 22», around the same © Angle with respect to the wall plane are bent, so that a going through the relevant kink line, on the wall level perpendicular plane has a plane of symmetry of the relevant Visible surface is. Me outline forms allemtlioh® ^ Impact surfaces such as 13, 14 are parallelogram-shaped.

In FIGS. 7 and 8, a section from a glass wall is shown, consisting of glass components according to FIGS. 5 land β is formed «As can be seen, the assembly of the glass building elements shown in the figure results from components with visible surfaces 18, 19, which form a table of uniform pyramids 31 with a square base surface, with each base line (buckling line 22 ^s ) neighboring pyramids is common. All abutting surfaces 15-16 lying next to one another in a row each fall into the same plane, so that the individual straight reinforcement irons 27 can lie flat over their entire length in depressions (not shown) in the abutting surfaces. The outline of each visible surface of the individual glass building element is also square, but the abutting surfaces lying in one plane, as seen in FIG. 14, run ziokzag-shaped. As can be seen particularly clearly from Fig. 8, due to the zigzag shape of the vertical and horizontal abutment surfaces, the total base of the components formed is almost twice as wide as that of the known, square-shaped glass components, which is achieved here by the fact that the perpendicular to the wall plane

The offset is so great that the reinforcing bars 27 are just inside the glass components are so that they do not protrude beyond the visible surfaces.

The glass component shown in Figs. 9 and 10 is characterized in that the one square Floor plan showing individual visual area 10, 11 through two central main kink lines 41 »42, which are perpendicular to one another and parallel to the wall plane, divided into four quadrants is, and that from the point of intersection 43 of the two main kink lines four ffeben kinklinien 44 to the same Distance from the four corner points arranged on the wall plane, like 45, go to the relevant visible surface, whereby the rope surfaces of the visible surface delimited by the folding lines are flat are. The outline of the abutment surfaces 13-16 is flat and has a non-rectangular shape, which is shown here consists of two abutting parallelograms.

That in the pig. 11 and 12 shown glass building element 17 has visible surfaces 10 and 11, each of which consists of two sub-areas separated by a crease line 50, such as 48 and 49, exist, which are symmetrical to a central plane of symmetry 50, which is perpendicular to the plane of the wall, and whose plan normals enclose an acute angle. This glass building element, which has both rectangular abutting surfaces, such as 14, as well as non-rectangular abutment surfaces such as 13, can form a component 12 by itself, such as this in Pig. 13 is shown, or in association with a further, identical glass component, a component 12
