Description
Description
The invention relates to a device for attaching fire protection panels to concrete structures, comprising a formwork for casting a concrete wall, at least one fire protection panel and at least one retaining device for the fire protection panel.
In the construction of various structures, especially tunnels, it is required to clad the walls with fire protection panels. These consist of a fireproof, heat-insulating material. For example, calcium silicate panels, cement silicate panels or panels containing gypsum can be used as fire protection panels.
These are usually adhered or doweled to the concrete of the tunnel walls. In places that are difficult to clad, such as steel beams, DE 37 03 778 A1 provides for a retaining device to be fastened to the fire protection panel and for the fire protection panel to be fixed to the beam by means of this retaining device using screws.
However, the subsequent assembly of the fire protection panels requires an additional work step.
Fire protection panels have become known from the AT 414 009 B, which are held by a reinforcement of a concrete structure. The GB 582 725 A discloses the fastening of a formwork sheet, which is removed after hardening of the concrete. Fire protection panels have become known from the DE 198 00 559 Al, which are placed on a ceiling formwork. The JP 2000 104223 A discloses disc-shaped retaining devices that can be adhered to a concrete structure to support the concrete structure. Finally, different variants of tunnel formwork have become known from the BE 488032 A.
Object of the invention
The object of the present invention is to optimize and simplify the fastening of fire protection panels and to present a method that simplifies the fastening of fire protection panels to concrete walls.
Brief description of the invention
This object is achieved by the invention in a surprisingly simple and yet effective way in that the fire protection panel has the retaining device on the side remote from the concrete wall, in that the retaining device is detachably fastened to the fire protection panel, in that the fire protection panel is held in position by the retaining device and by a support device attached thereto during concreting, and in that the fire protection panel is non-detachably connected to the concrete wall after concreting.
The retaining device is fastened to the fire protection panel in a manner that it is fastened to the fire protection panel on the side remote from the concrete. It therefore does not come into contact with the concrete and can be easily removed after concreting due to the detachable fastening.
The fire protection panel with the retaining device can be used as a formwork for casting the concrete wall itself, while the fire protection panel is detachably fastened to a support device through the retaining device, as well as to an existing formwork on the inside, e.g. to a formwork shell. The effect in both cases is that during concreting the concrete comes into contact with the fire protection panel, bonds with it, hardens and the fire protection panel is therefore firmly concreted to the concrete wall.
In this way, the fire protection panel is simply fixed in concrete when casting the wall. No further work step is necessary to fasten the fire protection panels. There are also no screws, nails or rivets that could corrode and/or come loose.
Preferred embodiments
The retaining device is adhered to the fire protection panel. In this way - depending on the choice of the adhesive - the fire protection panel can remain undamaged. In particular, it is not necessary to make holes in the fire protection panel, as would be the case with screwing or riveting.
It is advantageous and cost-effective if the retaining device is fastened to the fire protection panel with double-sided adhesive strip.
Particularly preferred is an embodiment of the inventive device, in which the formwork or support device has at least one retaining edge and the retaining device has an edging which engages behind the retaining edge of the formwork. In such a device, the fire protection panels can be easily and quickly mounted.
The retaining edge of the formwork is preferably an edge of an IPE beam (“double T-beam”). In this embodiment, a support device made of IPE beams is set up along the wall to be concreted. The fire protection panels can therefore easily be mounted in the side edges of the IPE beams using the retaining devices.
The retaining device consists of sheet metal, spring steel or plastic.
These materials are cost-effective and suitable for construction sites.
The retaining device is preferably reusable. This means that the user does not have to rebuild the retaining devices for each wall to be created, and a major cost saving is achieved.
The invention also comprises a method for installation of fire protection panels into concrete structures, comprising the following steps: constructing formwork or a support device for casting a concrete wall; fastening a retaining device to the fire protection panel by means of a detachable fastening, wherein the retaining device is bonded to the fire protection panel, and wherein the retaining device consists of sheet metal, spring steel or plastics material; positioning at least one fire protection panel in the installation or mounting position thereof; fastening the at least one fire protection panel in the installation or mounting position thereof to the formwork or support device; pouring the concrete into the formwork or into the fire protection panel provided with the support device; removing the formwork or support device and the retaining device from the at least one fire protection panel. A variant of the method according to the invention is preferred, in which the retaining device is removed simultaneously when removing the formwork or supporting device.
Ideally, the retaining device is fastened to the fire protection panel with a double-sided adhesive strip.
Drawings and detailed description:
Fig. 1 displays a schematic image of an exemplary embodiment of the inventive device in an exemplary mounting or installation situation;
Fig. 2 displays a schematic image of an exemplary embodiment of the inventive device after the concreting;
Fig. 3 displays a schematic image of an exemplary embodiment of the inventive device in a second exemplary mounting or installation situation;
Fig. 4 displays a schematic image of an exemplary embodiment of the inventive device or the inventive method.
Fig. 1 displays a schematic image of an exemplary embodiment of the inventive device 1 in an exemplary mounting or installation situation. A fire protection panel 2 is fastened to an IPE beam of a support device 6 by means of a retaining device 3. The retaining device 3 fastened to the fire protection panel 2 with an adhesive 4 covers the retaining edge 5 of the support device 6. In the exemplary embodiment selected here, the fire protection panel 2 forms one side of the formwork 9 (Fig. 3), a natural wall 7, for example a tunnel wall, forms the other side of formwork 9. Flowable concrete 8 is then poured into the formwork between the fire protection panel 2 and the wall 7 (arrow) and hardens. During this hardening process, one side of the fire protection panel 2 bonds inseparably with the hardened concrete 8.
Fig. 2 displays a schematic image of the situation after concreting. Concrete 8 has hardened and is now un-detachably connected to the natural wall 7 and the fire protection panel 2. The support device 6 (Fig. 1) has already been removed. Through the connection with the concrete 8, the fire protection plate 2 remains un-detachably in its installation or mounting position.
The retaining device 3 can now also be removed if it has not already been torn off or removed when the support device 6 was removed. The adhesive 4 is also removed. Any adhesive residues 4a are removed from the fire protection panel 2 by suitable means and any minor surface damage to the fire protection panel 2 caused by removing adhesive 4 from the surface of the fire protection panel 2 is repaired.
The layers in section depicted in Fig. 2, the fire protection panel 2, the concrete 8 and the wall 7 are un-detachably connected.
Fig. 3 displays a schematic image of another exemplary embodiment. One side of the formwork 9 is formed by the fire protection panel 2 itself, while the other side is formed by formwork panels 10. Alternatively, the other side of the formwork 9 can be formed by additional fire protection panels 2 instead of formwork panels 10.
Fig. 4 shows a schematic image of an exemplary embodiment. For example, the natural wall 7 can be a tunnel wall after drilling the tunnel. To stabilize the tunnel walls, they are reinforced with concrete 8. Due to fire protection regulations, the walls must generally be additionally clad with fire protection panels 2 so that the reinforcement made of concrete 8 or reinforced concrete is not damaged or protected in the event of a fire in the tunnel and the tunnel remains functionally stable. The advantage of the inventive method is that the fire protection panels 2 and the concrete walls 8 do not have any holes for screws or rivets and the work required to screw the fire protection panels 2 to the concrete walls 8 subsequently is also eliminated.
