Description

Wired glass with non-crossing individual wires The invention relates on a new, particularly appropriate arrangement of the wire insert with so-called Wired glass, through which compared to ordinary wired glass with rectangular or hexagonal Wire mesh insert and with wire insert in the form of straight parallel wires significant benefits can be achieved. The invention essentially consists in that the inserted wires do not cross, as with the wire inlays, wire mesh conventional type. In a sense, only wires are used which run in one main direction, that is, preferably in the longitudinal or transverse direction, are inserted, but in turn do not run straight and parallel, as already known, but in wavy lines are arranged. In special cases it can also be advantageous to use a waveform instead of several inlaid wires, a single continuous wave-shaped wire is used, which is bent accordingly near the edges of the glass sheet.

Three exemplary embodiments are shown in the drawing. Fig. i is a plan view of a section from a wire glass panel with undulating inlaid Wires. Fig. 2 is a schematic cross-section along line A-B of that shown in Fig. I Wired glass type. Fig. 3 is a plan view of a wire glass panel with only one undulating one Wire. Fig.q. is a cross-section along line C-D of Figure 3. Fig.5 is a floor plan another embodiment of the single wave-shaped inlaid wire. Fig 6 Figure 5 is a cross-section of Figure 5 along line F-F.

In the embodiment according to Fig. I, a plurality of individual wires b are embedded in the glassa and arranged in a wave-like manner. The individual wavy lines are expediently always at the same distance from one another. The waves interlock so deeply that a tangent G to which one wavy line e intersects the neighboring wavy line f. In this way it is achieved that, if such a glass sheet breaks, the two fragments are always held together by several wire cross-sections, regardless of the direction in which the break line of the glass runs. This is the advantage of wire glass with a wave-shaped wire insert compared to wire glass with parallel, straight individual wires. With the latter there is the possibility that if there is a crack parallel to the wires, the two fractions will be completely separated from each other, which, depending on the location of the cause the two halves to fall out, creating a serious hazard.

In the embodiment according to Fig. 3 and q. lies a wavy Single wire rl embedded in the glass a. The individual cross sections of Wire d are arranged parallel to each other in this embodiment and have expediently constant distance from each other. The wire is near the edge of the glass panel bent over so that one of the parallel lines is converted into the other.

If such a sheet of glass breaks, the two become fragments always held together by at least one wire cross-section, even then if the break point is parallel to the transverse wire segments. Then you have to the break line will still go through the reversal point of the wire.

In the embodiment according to Fig. 5 and 6 are also the most unfavorable in this Break at least three wire cross-sections that hold the break point together, as can be seen from the cross section (Fig. 6).

As little as it is necessary that the wire at the turning points after a Semicircle is curved, so little is it necessary that the transverse wire sections are straight as shown in Fig. 3 or angled only once as shown in Fig. 5. It can any other shapes can also be chosen; it is only essential that in this case Embodiment only a correspondingly long, corrugated wire housed in the glass will. Of course, it is expedient to remove the individual paths of the wire hold each other evenly.

The advantages of the new wired glass compared to ordinary wired glass with wire mesh inlay are readily apparent. The light transmission is greater, the amount of wire required is less when using individual wires.

Another major advantage of this wire glass is that the load-bearing capacity of the glass plates with individual wires is greater than that of glass plates with wire mesh inlays. The proportions are straight for glass vice versa as with reinforced concrete. The load-bearing capacity of the glass is determined by the Wire mesh inserts weakened; Glass without a wire insert has greater strength as such with a wire insert, which is why it is desirable to have the wire cross-section to a minimum. Except for the larger cross-sectional weakening that the wired glass with speckled or fabric-shaped insert learns through the insert itself is note that this wire glass tends to break more easily than z. B. raw glass, d. H. Glass without wire inlay, because the embedded ones at the junctions and intersections Wire mesh, air bubbles will always form, which will reduce the glass cross-section and which usually form the starting point for cracks. To this diminished Glass cross-section, which will have a purely mechanical effect, is followed by the physical one Added phenomenon that glass and iron have different coefficients of expansion, which is why internal tensions are produced when the wire inlay is melted in the glass itself will. These stresses are all the greater, the greater the embedded iron cross-sections are, and are naturally particularly dangerous at the junctions and intersections the embedded wire mesh. According to the inventor's observations, which have a Have been employed for several years, the cracks in the glass show up more often at these junctions and jump on from there.

Avoiding these nodes thus becomes one of the most important The causes of cracks in wired glass and thus the breakage damage are eliminated significantly reduced without the task of fulfilling the wire insert in the glass has, is less fulfilled.

But this is where the progressive effect of the invention lies Wired glass compared to the hitherto common wired glass with straight, parallel lines Wire inlays. This wired glass with straight and parallel wire inlays avoids probably the shortcomings of wire glass with embedded wire mesh, but this improvement the load-bearing capacity and the light transmission as well as the reduction in price due to the Less expenditure on embedded wire has to be bought at the expense of the breakage will. In the case of wired glass with straight, parallel wire inlays, this means Wire only has a limited protection against breakage in the case of cracks that are perpendicular run to the direction of the wire or cut the direction of the wire at an angle. at Cracks - but that are parallel to the wires or at very acute angles to them run, there is still the possibility of breaking through the glass panels, because the tear line does not cross a wire cross-section.

The wired glass according to the invention connects with an undulating wire insert thus the increased security of the wire glass with fabric or braid insert the advantages of wired glass with single wires. One achieves through it an advanced effect achieved by achieving increased level of security with greater load capacity in a wide variety of areas, such as for automobile windscreens, apartment and factory glazing of all kinds, putty-free Glass roofs, is of paramount importance.
