Abstract: The invention relates to a fixing element (10) for double pane insulating glass (42, 44), which is anchored by expansion of an expansible ring (16) in a drilled hole having a conical undercut in an outer glass pane (42) of the insulating glass (42, 44). The invention provides for the fixing element (10) to be sealed with two sealing rings (30, 40) on both sides of an inner glass pane (44) of the insulating glass (42, 44) and additionally for an injection opening (41) to be provided, through which a sealing compound, for example, silicone, can be introduced into a gap at the point at which the fixing element (10) passes through the inner glass pane (44) in order to provide an extra seal at the passage point. The fixing element (10) ensures a permanent seal of the passage point.

Abstract: The invention relates to a fixing element (10) for anchoring in a drilled hole (30, 32) having an undercut (28) in a laminated body (24, 26), for example, laminated glass. The fixing element (10) has an expander cone (14), onto which an expansion ring (16) can be pushed. To be able to compensate for misalignment between the layers (24, 26) of the laminated body (24, 26), the drilled hole (30) in an outer layer (24) is drilled with a larger diameter than in a further layer (26) of the laminated body (24, 26). The invention proposes constructing a washer (18) of the fixing element (10) with an injection opening (22), through which the gap between a threaded shank (12) of the fixing element (10) and the wall of the drilled hole (30) in the outer layer (24) of the laminated body (24, 26) can be filled with a sealing compound (26)2. (FIG. 2).

Abstract: The invention relates to a retaining means (10) for fixing panel-form material, for example, glass panes (12) of a glass facing, to a substructure (14). The invention proposes constructing the retaining means (10) with a support (16), in which supporting elements (22) projecting pivotally to the side are insertable, to which the glass panes (121) can be displaceably fixed. The invention has the advantage that in a simple and inexpensive manner it permits stress-free fixing of glass panes (12) so that thermal expansion is compensated.

Abstract: A device (10) for fixing facing panels (14) to a wall (16) by means of a transverse support (12), on which the facing panels (14) can be suspended. To render the transverse support (12) stable, the invention proposes constructing the transverse support (12) as a closed, hollow profiled member. This has the advantage that even heavy facing panels (14) can be mounted on the wall (16). Moreover, the invention proposes vertical supports (32) for mounting the transverse support (12), which are to be mounted on the wall (16) at a distance therefrom by means of length-adjustable rods (42), which are pivotally connected to the vertical supports (32) and to the wall (16). A single rod (42) forms a movable bearing (40) and two rods (42) mounted at an angle to one another form a fixed bearing (38). The advantage of this method of mounting the transverse support (12) on the wall (16) is the ease of vertical adjustment and ease with which wall unevenness can be accommodated.

Abstract: The hardenable mortar composition consists of a bonding agent component including a hydraulic bonding agent, such as cement, gypsum or mortar, and a paste-forming agent consisting of a liquid solvent inert with respect to the hydraulic bonding agent, and an aqueous component kept separate from the bonding agent component until the two components are mixed to form a hardened mortar composition. The aqueous component includes water and a hydrophobic adsorbent or absorbent. The hydrophobic adsorbent or absorbent is included in the aqueous component to avoid the emergence of the paste-forming agent, which is at the very least unsightly, when the aqueous component is mixed with the bonding agent component. The hydrophobic adsorbent or absorbent binds the paste-forming agent which would otherwise escape during mixing and remains as an inert additive in the setting mortar composition, without reducing the hardness thereof.

Abstract: The drilling device has a radially resilient shaft (3) which allows radial displacement of the drill bit (4) and the drill head (5). The radial displacement can be caused by a vibration device (8), but a self-excited oscillation of the resilient shaft (3) can also provide the desired radial displacement of the drill bit and the drill head. The drill shank (2) has a sleeve-shaped shank extension (17) provided with a damping chamber (18) filled with a damping agent (19) and the resilient shaft (3) is in the damping chamber (18) which is sealed by a radially resilient seal (21) surrounding the resilient shaft (3).

Abstract: The double connector for connecting two bodies, especially for connecting two slabs of stone, marble or the like, consists of two anchoring elements (4,5), one in each body being connected, and a sleeve-like connecting piece (1) including two stud parts on opposite ends. The connecting piece (1) is connectable with the stud parts on the anchoring elements located in drilled holes provided in the bodies. So that the double connector, in addition to having a simple assembly, can absorb comparatively large tensile and compressive forces, at least one anchoring element (4,5) consists of an expansion element (7) received in one (13) of the drilled holes and a anchor core (6) consisting of a cone (8) and a bolt part (6') extending from the cone (8) and provided with a bolt collar (9) spaced from the cone (8). The bolt collar (9) of the bolt part (6') engages or locks in a suitable undercut (15) provided in one of the stud parts.

The substructure has supporting elements (6) on which profiled panel supports (2) connected to the rear side of the facing panels can be hung. The supporting elements (6) include, for each facing panel element (5), one locating supporting element (7) and at least three non-locating supporting elements (8). The locating supporting element (7) is preferably arranged in an upper corner region of a facing panel element (5) and is fixedly connected to the corresponding profiled panel support (2) of the facing panel element (5). Furthermore, the locating supporting element (7) has an adjusting means allowing horizontal and vertical adjustment. The non-locating supporting element (8), preferably at the other top corner region of the facing panel element (5), is likewise provided with an adjusting means for vertical adjustment.
