Description

Vibration-damped composite arrangement for glass facades

The invention relates to a composite arrangement for glass facades, are mounted in the glass sheets on a frame construction, preferably on a frame construction made of wood.

The attachment of glass panes to a wooden frame construction requires the solution of a variety of problems that arise when joining glass to wood due to the different mechanical properties of both materials.

A first requirement with such a composite arrangement is the expansion compensation between the glass plates and the wooden frame construction in the event of temperature differences.

It is well known to attach glass plates to a frame construction by means of adhesive. If the adhesive layer is made sufficiently thick, the glass pane can move tangentially with respect to the frame construction without the adhesive breaking off. In addition to these tangential forces caused by thermal expansion, alternating wind loads also cause vertical forces, which lead to a changing concave and convex curvature of the discs. Here, the discs are subjected to bending. Depending on the local wind conditions, these bends can occur relatively frequently and produce vibrations of different frequencies and amplitudes. Even earthquakes can cause such vibrations. In this respect, the holding surfaces to which the glass pane is glued, absorb forces that can act in different directions.

It is therefore sought after a composite arrangement in which at the attachment point of the glass plates to the timber construction, the following requirements are met: Compensation of mechanical stresses caused by different expansion coefficients of wood and glass materials in temperature fluctuations and degradation of mechanical stresses caused by Wind forces or earth tremors arise.

This object is achieved with a composite assembly according to claim 1, wherein the composite assembly has the following features; Disk holding rails for holding the glass pane, wherein the disk holding rails have a mounting leg for attachment to the substructure and a Klegebenkel for adhering to the glass, the mounting leg adjoins the adhesive bead laterally and wherein in the composite state with a damping agent completely or partially filled damping gap is formed between the underside of the adhesive skirt and the top of the substructure and further formed a mounting gap between adjacent glass sheets.

This composite arrangement has the following advantages: The adhesive leg spaced apart from the surface of the substructure has, in addition to the fastening function, additional functions. A damping gap is formed, which is completely or partially filled with a predetermined damping means. If the disc bends under the influence of wind forces the adhesive bead, the volume of the damping gap is alternately larger and smaller, ie the damping means, for. As a rubber with predetermined damping properties, is alternately compressed and relieved. When the damping means is connected to the underside of the adhesive skirt and the top of the substructure, the damping means is compressed and pulled apart. The size of the damping gap and the damping means are selected by the skilled person so that caused by the external influences Vibrations of the glass panes are sufficiently damped to avoid breaking the glass panes.

According to claim 2, one of the disk support rails is flat, the other cranked formed and in the composite state of the mounting leg of the planar disk holding rail on the mounting leg of the cranked disk holding rail is arranged. The advantages of this variant are that the flat disc retaining rail is particularly inexpensive to produce. According to claim 3, the flat and the cranked disk holding rail is provided with a collar as a stop for the glass sheet. This collar makes it easier to align the pane retaining rail to the glass pane during gluing and, in a horizontal position, supports the pane, which relieves the glued area.

According to claim 4, a groove is provided at the top of the substructure and the mounting leg of the disc support rails has a stop portion as a stop for the glass and a support and spacer portion for supporting in the groove and to provide the distance for forming the damping gap. The advantages of this embodiment are the same as those of the embodiment according to claim 3. A further advantage is that when replacing a disc only the disc-holding the disc to be replaced must be solved. According to claim 5, the Scheibenhalteschienen a Quersch ness in L-shape, which overlap in the composite state whose attachment leg. In addition, a spacer or a material collection is provided under the overlapping point. This embodiment of the invention is particularly inexpensive to produce.

According to claim 6, one of the contact surfaces between mutually opposite mounting legs is convex. The spacer or the material collection is convex. The advantage of this embodiment Form is that the wind-induced vibrations of the glass panes are well received by the disk holding rail, so that higher mechanical stresses on the disk edges are avoided. According to claim 7, the mounting gap is sealed with a seal, so that penetration of moisture from the outside is avoided.

According to claim 8 different damping means are used, which are arranged alternately in the damping gap. This development of the invention has the advantage that the damping properties can be adapted to the vibration profile of the pane along the edge of the pane.

The invention will be explained in more detail with reference to drawings, wherein like features are provided with the same reference numerals.

Fig. 1 shows as a first embodiment of a composite assembly in which two composite glass sheets are attached to a substructure. In the figures, reference numeral 2 designates the substructure on which the glass panes 1 are to be held. Reference numeral 3 denotes a disk holding rail which has a fixing leg 3a for fixing to the substructure 2 and an adhesive leg 3b for adhering to the glass sheet 1. The fastening leg 3a adjoins the adhesive leg 3b laterally. In this embodiment, one of the Scheibenhal- teschienen 3 is flat, the other executed cranked. In the composite state, the mounting leg 3a of the planar disc retaining rail 3 overlaps the mounting leg 3a of the cranked disc retaining rail 3. To secure the disc retaining rails 3 to the substructure 2 screws 9 are screwed through holes in the overlapping mounting legs 3a in the substructure 2 and in this way the glass sheets. 1 attached to the substructure. In this state, a damping gap 4 is formed between the upper side of the substructure 2 and the underside of the adhesive leg 3b, which is completely or partially filled with a damping means.

Reference numeral 5 designates a mounting gap that is at least so wide that a screwdriver fits in or out of the fastening screws 7 therebetween.

The reference numeral 8 denotes an adhesive layer between the glass sheet 1 and the adhesive bead 3b. The adhesive layer 8 is selected to be sufficiently thick so that temperature-induced changes in length in the direction of arrow A, see FIG. 1 a, are compensated and this adhesive layer 8 is not torn off by the shear stress.

The arrows B, see Fig. B, denote the pivotal movement of the glass plates 1 with changing wind load. This pivoting movement is transmitted to the adhesive bead 3b. As a result, the damping gap 4 alternately increases and decreases, ie, the damping means is compressed and relieved. Fig. 2 shows a second embodiment of the composite arrangement. The second embodiment differs from the first embodiment only in that the disk holding rails 3 are provided with a collar 3c. The collar 3c extends at right angles from the adhesive bead 3b, serves as a stop when placing the disc retaining rail on the glass pane 1 and thus facilitates the alignment of the disc retaining rail 3 on the glass pane 1. Furthermore, the waggerechte lower collar 3c carries the weight of Glasscheibe.1.

FIG. 3 shows a third embodiment of the composite arrangement. The third embodiment differs from the first embodiment in the following: The top of the substructure 2 is provided with a groove 2a. The mounting leg of the disk holding rail 3 connects at right angles to the adhesive bead 3b and has a stopper portion 3d as a stop for the glass sheet 1 and a support and spacer portion 3e for supporting in the groove 2a and to provide the distance for the formation of the damping gap 4. Another advantage is that when replacing a disk 1, the disk holding the disc to be replaced can be solved very easily. FIG. 4 shows a fourth embodiment of the composite arrangement. The fourth embodiment differs from the first embodiment in that the disk holding rails 3 have a cross section in L-shape, are fixed in two planes offset by 180 degrees from each other to adjacent glass sheets 1 and in the composite state whose mounting legs 3a overlap. In addition, one of the attachment legs 3a is formed convex on the contact surface with the opposite attachment leg 3a. Another difference from the first embodiment is that a material elevation is provided on the upper side of the substructure 2 or a spacer 2b is provided below the overlapping point. The material elevation or the spacer 2b is also convex. Wind-induced vibrations of the glass panes are well absorbed by the disk-holding rail, so that mechanical stresses that occur at the disk edges during vibrations can be reduced.
