Description

(1) The invention is explained in greater detail below on the basis of a drawing representing merely an example of embodiment; in the figures:

(2) FIG. 1 shows a dry-built ceiling or dry-built wall according to the invention in a diagrammatic cross-sectional representation,

(3) FIG. 2 shows the fastening element according to the invention used to produce the dry-built wall or dry-built ceiling according to FIG. 1, in a perspective view, and

(4) FIGS. 3 and 4 show different views of the fastening element according to FIG. 2.

(5) A dry-built ceiling or dry-built wall is represented in the figures, which is equipped according to FIG. 1 with a framework 1. Within the scope of the example of embodiment, framework 1 is a vertical C-profile rail 4 as an upright profile 4. As a rule, a plurality of vertical C-profile rails 4 are provided, which moreover are or can be connected to one another by horizontal C-profile rails 4 or otherwise. A plurality of construction panels 2 are fixed to framework 1 in question. Construction panels 2 can be plasterboards, fibre-reinforced plasterboards, wooden panels, plastic panels, metal panels or also combinations. A wall 3 can thus be lined with the aid of construction panels 2. In principle, however, the dry-built ceiling or dry-built wall thus produced can also be freely arranged in a room, so that construction panels 2 are located on both sides of the framework 1.

(6) Individual construction panels 2 are fixed to associated upright profile 4. In the context of the example of embodiment, upright profile 4 is C-profile rail 4 with C-legs 4a and a C-base 4b.

(7) Within the scope of the invention, construction panels 2 are fixed to upright profile 4 with the aid of fastening element 5. It can be seen from FIGS. 2 to 4 that fastening element 5 is constituted essentially U-shaped. Fastening element 5 in fact comprises two fastening legs 5a and a fastening base 5b. Moreover, it can be seen that fastening element 5 is equipped with lug ends 6 and hooks 7. Two hooks 7 are in fact provided, which are disposed on both sides of lug end 6 located in between. Both hooks 7 and respective lug end 6 are connected at the top to associated fastening leg 5a and extend at the top of respective fastening leg 5a.

(8) The layout is made in such a way that both hooks 7 and respective lug end 6 have an approximately identical spacing from common fastening faces 5b and, as already described, are each connected at the top end to associated fastening leg 5a. At the connection of lug end 6 to associated fastening leg 5a, it is noteworthy that a material weakening zone 8 is interposed at this point. Material weakening zone 8 is a perforation 8. This means that fastening leg 5a transforms at the top first into material weakening zone or perforation 8, which is then followed by respective lug end 6. Respective hooks 7 are provided on both sides of material weakening zone 8 or lug end 6.

(9) It can be seen that respective hooks 7 are constituted as spring hooks. Furthermore, hooks 7 comprise a hook head directed in each case into the interior of fastening element 5 or inwards, which hook head is pressed back in a spring-elastic manner when the fastening element 5 is fitted to upright profile 4 or associated profile rail 4 and usually engages at the end over associated profile leg 4a of upright profile 4. Fastening element 5 can thus be pre-fixed to upright profile 4. This is because hooks or spring hooks 7 ensure that in each case they engage over or engage behind the end of profile leg 4a, so that fastening element 5 is fixed to C-profile rail 4, but can continue to perform a relative movement with respect to upright profile 4, i.e. in the longitudinal direction of upright profile 4.

(10) In the context of the pre-fixing, fastening element 5 can be clipped, as it were, to upright profile 4, wherein fastening element 5 can be displaced along upright profile 4 or associated C-profile rail 4. Fastening element 5 can thus be fixed by a drywall constructor precisely at the point where construction panel 2 to be fitted thereto is to be positioned. Only in the course of the final fixing are lug ends 6 placed in position on respective profile leg 4a of upright profile 4 or placed in position around profile leg 4 in question, as is represented in FIG. 1. Fastening element 5 is then fixedly connected or finally fixed to upright profile 4.

(11) As an alternative to this, respective lug end 6 can however also be placed in position on profile leg 4a in question, as is indicated in the left-hand part of FIG. 1. A further construction panel or a plurality of further construction panels 2, for example, can then follow to the rear on upright profile 4. Moreover, it is possible for lug end 6 to be fixed to base 3, as is shown in the right-hand part of FIG. 1. In this case, upright profile 4 can serve, in connection with construction panels 2, as a lining of base 3.

(12) It is the case for both variants that fastening element 5 is thus equipped, in addition to with the at least two lug ends 6 for the final fixing, with the two hooks 7 for a pre-fixing to respective profile leg 4a of upright profile 4. After the pre-fixing, fastening element 5 can be displaced along upright profile 4 into the desired position. Fastening element 5 is thus equipped, in addition to with the at least two lug ends 6 for the final fixing, with the two hooks 7 for its pre-fixing to respective profile leg 4 of upright profile 1.

(13) Only when its final position is reached and meets to the expectations of the drywall builder does the final fixing take place. For this purpose, the one lug end or the two lug ends 6 are bent over. This bending process is facilitated by perforation 8 interposed in each case. This means that, having regard to material weakening zone or perforation 8, lug end 6 can be bent over or bent off at virtually any angle with respect to fixed and associated fastening leg 5a.

(14) In the context of the example of embodiment, lug end 6, respective hook 7, fastening leg 5a and finally fastening base 5b are produced in a uniform material from a metal and for example steel. The production can be carried out in one operation by typical punching/bending steps, so that fastening element 5 can be produced in a particularly straightforward and cost-effective manner. In addition, fastening element 5 is typically provided with a coating and in particular a zinc coating in order to prevent any corrosion. Moreover, fastening element 5 has a mirror-symmetrical configuration in relation to a central plane of symmetry S, which is indicated only in FIG. 2. The production is thus further facilitated.

(15) U-base or fastening base 5b of the fastening element 5 is as a rule available for the fitting of construction panels 2 to fastening element 5. In point of fact, use is usually made here of connecting means 9, with the aid of which respective construction panel 2 is fixed to fastening element 5. Connecting means 5 in question can be a lug fixed to U-base 5b or also a separate screw etc. In the example of embodiment according to FIG. 1, connecting means 9 is constituted as a lug engaging in a groove of respective construction panel 2. This is of course only by way of example. This is because, in principle, construction panels 2 can alternatively also be connected adhesively to the U-base of fastening element 5 oras already describedby screwing or otherwise.

(16) Fastening element 5 can be coupled with profile rail 4 in fundamentally different ways. Thus, it is conceivable for fastening element 5 in the fitted state to lie in each case with its fastening legs 5a adjacent to associated fastening legs or C-legs 4a of profile rail 4. U-base 5b of fastening element 5 and C-base 4b of profile rail 4 can also be disposed in contact with one another, as represented in FIG. 1. As an alternative to this, however, it is also possible for U-base or fastening base 5b of fastening element 5 and C-base 4b of profile rail 4 to be spaced apart from one another. This is not however represented in detail.

(17) Fastening means 9 can be disposed in any way on U-base 5b of fastening element 5. Transverse arrangements and/or longitudinal arrangements are thus conceivable and lie within the scope of the invention. A detachable fixing of fastening means 9 to respective U-base 5b of fastening element 5 is also covered by the invention.

(18) As a result of the possible pre-fixing of respective fastening element 5 to C-profile rail 4 or the C-profile rail, it is possible to pre-assemble framework 1 within the scope of the invention not only as described, but also C-profile rails 4 can be supplied in common together with fastening elements 5 in a pre-fixed state. The number of transported parts and parts to be kept in stock is thus reduced and the outlay on assembly and erection is also reduced. It is in this that the main advantage is to be seen.
