Description

The invention relates to a revision device, with a revision frame and a usable in the revision frame inspection cover.

Such revision devices or revision covers are known in practice and are otherwise in the EP 1 516 978 A1 described. Usually, the inspection device or inspection cover is used to provide a wall / floor / or ceiling panel with an openable and closable cover to wait behind the respective panel located installations, install additional installations, etc.

The inspection cover can be hung in the inspection frame or hinged to this, as shown in the EP 1 516 978 A1 is described. When installing the inspection device is usually taken to ensure that the previously mentioned panel or provided at this point planking, for example, several panels flush with the revision frame respectively the inspection cover, since in practice, depending on the local requirements for example general building physics Claims with very different thicknesses of the planking or cladding respectively different body thicknesses is worked, you have so far for almost any installation made its own revision device. Of course, this leads to high production and assembly costs, Here the invention aims to provide a total remedy.

The invention is based on the technical problem of further developing such a revision device such that in particular the manufacturing and assembly costs are significantly reduced.

To solve this technical problem, the invention proposes in a generic revision device that the revision frame and / or the inspection cover have one or more attachment means for selectively attaching at least one lid and / or frame extension component.

According to the invention so the revision frame respectively the inspection cover - both together or individually - equipped with at least one fastening means. This attachment means serves to be able to attach at least one additional cover and / or frame extension component. This cover and / or frame extension component is usually realized in addition to the already provided planking or lining of the revision device.

D. h., The revision device according to the invention is generally equipped with a kind of standard planking or standard insulation panels in terms of their revision frame and / or revision cover. This standard planking can now be further improved depending on the actual local requirements, for example with regard to sound insulation, radiation protection, smoke protection or even fire protection. Serve this purpose, the one or more cover and / or frame extension components, which are fixed to the at least one fastening means.

The respective cover and / or frame extension component is generally a sound, radiation, smoke and / or fire protection enhancing component. It is particularly preferred in this context if the lid and / or frame extension component is designed as a sound and / or radiation, and / or smoke and / or fire protection insulation board. Also one or more sound and / or radiation and / or smoke and / or fire protection Dämmstreifen may be implemented at this point additionally or alternatively.

As a material for the insulation board in question or the insulating strips, the invention recommends recourse to plasterboard, mineral fibers, calcium silicate plates, steel, plastic or composite plates, ie those that are composed of several of the aforementioned materials. Likewise, it is generally possible to use non-flammable materials in order to realize the mentioned insulation boards or insulating strips. The standard planking or the standard insulation panels can also be constructed or assembled from the abovementioned materials. That depends on the specific requirements regarding sound insulation, radiation protection, fire protection, smoke protection, etc. It is of course within the scope of the invention to provide supplementary sealing measures, for example to work with additional inflatable seals, which enclose the respective cover and / or frame extension component or cover remaining column in case of fire.

In order to fix the respective cover and / or frame extension component properly on the fastening means, the invention proposes at this point a non-positive and / or positive connection with the fastening means. In addition, it is possible to releasably couple the lid and / or frame extension component to the fastener to ensure repaired replacement, replacement, etc.

It has additionally proved useful if the non-positive and / or positive connection with the fastening means additionally has a locking device or can be locked. For a once achieved fire protection, smoke protection, sound insulation or radiation protection should not be able to be changed in the rule, which would be the case if the release respective lid and / or frame extension component from the fastener. This prevents the optional locking device, which prevents the solvability in case of need.

For realizing the non-positive and / or positive connection, it has proven to be favorable, whether the locking device is additionally realized or not, if the cover and / or frame extension component have a fastening element and the fastening means have a counter-fastening element, or vice versa. In the case of a latching connection between the fastening means and the cover and / or frame extension component, the fastening element may be designed as a latching nose, while the counter-fastening element constitutes a latching groove. Of course, the reverse can also be done.

Since the fastening means is usually designed as an L-shaped fastening web or includes such and incidentally exists as a metal profile, a fastening element or counter-fastening element in this metal profile can be easily represented. In fact, the fastening element or counter-fastening element may be designed as a nose or elongated nose ridge formed in the metal profile, whereas the counter-fastening element constitutes an associated (elongated) groove or groove channel in the cover and / or frame extension component. It is just as easy to do the reverse. Then the fastening means or at this point usually realized metal profile is equipped with a counter-fastening element in the form of a groove, in which engages a nose as a fastener on the cover and / or frame extension component. Of course, both fastening element and counter-fastening element can be realized on the fastening means such as the lid and / or frame extension component.

It has proven useful if the fastening means has two opposite and forming a terminal receiving L-shaped fastening webs or L-leg. Because this terminal mount can easily hold an insulation board and / or a Dämmstreifen or even several insulating strips or insulation boards. This applies both to the revision frame and the inspection cover.

In addition, it has proven useful if the fastening means is connected to a frame profile and / or cover profile. This can be done via a latching, riveting, screwing or comparable connection. According to a preferred embodiment, the fastening means and the frame profile and / or cover profile are made in one piece. This is particularly advantageous because the fastening means - such as the frame profile and the cover profile - is usually designed as a metal profile. As a metallic material, the invention recommends recourse to aluminum, steel o. The like., Of course, combinations are conceivable. In addition, the frame profiles and / or cover profiles as well as the fastening means can be configured as plastic profiles.

In order to achieve a total complete coverage of the inspection cover and / or the revision frame with the cover and / or frame extension component or the plurality of cover and / or frame extension components, it has proven useful if the attachment means the revision frame and / or the inspection cover in whole or in part encloses. In this case, the fastening means may be embodied as a respective (circumferential) extension web connected to the likewise generally continuous frame profile or cover profile.

As a result, a revision device is provided which is usually equipped with respect to the inspection cover and / or the revision frame with a standard planking, which has no special properties in terms of sound insulation, radiation protection, smoke protection or fire protection. The revision device in question is now always equipped with the one or more attachment means, the respective attachment means for attaching a cover and / or frame extension component is then not used when the standard paneling or the standard insulation panels respectively standard insulation strips at the actual installation location sufficient for the local requirements.

However, if the real installation situation requires a special adaptation to, for example, increased fire protection, the one or more fasteners will be used to define one or more cover and / or frame extension components thereon. These cover and / or frame extension components are additional insulation boards and / or Dämmstreifenn, namely sound and / or radiation and / or smoke and / or fire protection insulation boards and / or -Dämmstreifen. These insulation boards and / or insulating strips, in conjunction with the standard planking or the standard insulating boards and / or insulation strips, ensure that the increased requirements, in the example case of increased fire protection, are taken into account.

Always one and the same inspection device is used, without being distinguished from the production between embodiments with and without fire protection in the example case. Because the one or more fasteners are realized by default. Only at the installation site is the equipment and upgrading of the inspection device in view of the specific requirements. As a result, the total manufacturing costs reduces and at the same time the total assembly costs are reduced. In addition, the invention ensures that the variant variety pursued by the prior art is significantly restricted, as a result of which, of course, the sales and transport costs are also reduced. Here are the main benefits.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. The single drawing shows the revision device according to the invention in a schematic side view.

In the single figure, a revision device is shown, which includes a revision frame 1 and an insertable into the revision frame 1 inspection cover 2 in their basic structure. Both the inspection frame 1 and the inspection cover 2 are covered or equipped with a standard planking 3. These standard planking 3 may be respective plasterboard panels or generally standard insulation panels or standard insulation strips, which may be connected to respective metal profiles 5, 6 with the aid of fastening devices 4, in the present case screws 4.

The fastening means 7a, 7b are each designed as L-shaped fastening webs or include such a fastening web. Like the frame profile 5 and the cover profile 6, metal profiles 7a, 7b are also used in the fastening means 7a, 7b.

In the context of the embodiment and not limiting both the frame profile 5 and the cover profile 6 are each equipped with two opposing fastening means 7a, 7b. Here are the respective fastening means 7a, 7b integrally connected to the associated profiles 5, 6. It can be seen that the respective fastening means 7a, 7b are connected in front view in each case in the rearward extension to the respective corresponding profile 5, 6.

The frame profile 5 forms together with the associated fastening means 7a, 7b a one-piece metal profile as well as the cover profile 6 with the associated fastening means 7a, 7b. As a material for the production of said profiles 5, 6, 7a, 7b, the invention recommends recourse to aluminum, steel or combinations. The respective profile can be designed as a continuous extruded profile, roll profile, etc. The exemplary embodiment makes use of a respective continuous or circulating profile 5, 6, 7a, 7b, which in the present case is not rectangular in shape and not restrictive in each case. Of course, profiles 5, 6, 7a, 7b can be used with sectional openings. The rectangular or circular shape of the profile 5, 6, 7a, 7b depends on the shape of the opening to be closed.

Either way, the design in the example case and not restrictive is such that both the frame profile 5 and the cover profile 6 as the associated fastening means 7a, 7b are formed as a circumferential rectangular profiles (or circular profiles) in total and the closure of a (also rectangular) Opening 8 in a ceiling / floor / wall cladding serve.

The fastening means 7a, 7b are in the present case designed as L-shaped fastening webs, wherein in the case of the fastening means 7a, 7b for the frame section 5, two L-shaped fastening webs 7a, 7b are opposite and thus form a clamping receptacle 9. The same applies to the opposing L-shaped fastening webs 7a, 7b of the cover profile. 6

The fastening means 7a, 7b serve to selectively fix one or more cover and / or frame extension components 10, 11 on the inspection frame 1, respectively, on the inspection cover 2. In fact, these frame extension components 10, 11 are those components which are shown in the single figure above the inspection device in the uninstalled state with corresponding mounting arrows and an insulation board 10 and two or four Dämmstreifen 11 represent.

The insulation board 10 serves to make the inspection cover 2 or the existing there Standardbeplankung 3 so that the inspection cover 2 a certain building physics requirement, z. B. a given fire protection class, falls. The same applies to the inspection frame 1, which is accordingly improved with the help of the insulating strip 11. Alternatively, the insulation board 10, respectively, the insulating strips 11 can also be used to the revision frame 1 respectively the revision cover 2 with regard to increased sound insulation or radiation protection or smoke protection to endurance.

D. h., In the respective cover and / or frame extension component 10, 11, it is generally a sound, radiation smoke and / or fire protection rising component. For this purpose, the cover and / or frame extension component 10, 11 in question is non-positively and / or positively connected to the associated fastening means 7a, 7b, and in the context of the example releasably coupled to the fastening means 7a, 7b.

In the exemplary embodiment and not restrictive, a predominantly positive and largely positive connection of the respective insulating board 10 and the insulating strip 11 with the associated fastening means 7a, 7b is used. For this purpose, fasteners and counter-fastening elements 12, 13 realized. It can be seen that the fastening means 7a, 7b is L-shaped equipped with an L-leg 7a and an L-leg 7b, which form an L-shaped receptacle 9 for the insulation board 10 respectively the respective Dämmstreifen 11.

The fastening element / counter-fastening element 12, 13 is attached to only one L-leg 7a of the L-shaped fastening means 7a, 7b, namely to a limiting leg 7a. In contrast, the other L-leg 7b acts as a support leg. The limiting leg 7a is substantially vertical on the support leg 7b. The support leg 7b extends for the most part in a plane spanned by the standard panel 3 level.

On the basis of the enlarged illustration in the single figure it can be seen that the limiting leg 7a in the exemplary embodiment has a fastening element 12 in the form of a (circumferential) fastening lug. On the other hand, the cover and / or frame extension component 10, 11 or the insulating panel 10 or the insulating strip 11 to be positively or positively connected thereto is equipped with a corresponding (likewise circumferential) counter-fastening element 13. The counter-fastening element 13 is a fastening groove 13 cooperating with the fastening lug 12.

Both the fastening lug 12 and the fastening groove 13 are provided circumferentially over the entire length of the fastening means 7a, 7b. The fastener 12 can be easily defined herein during extrusion or roll rolling of the associated metal profile 5, 6, 7a, 7b. In the same way, the fastening groove 13 can be introduced into the insulation board 10 or the insulating strips 11 during manufacture.

Both the insulation board 10 and the respective insulating strip 11 are equipped with stops 15 which engage over the fastening means 7a, 7b or the limiting leg 7a in the installed state. As a result, at the same time the installation depth of the insulation board 10 and the Dämmstreifens 11 and also the respective installation position. Depending on the topological conditions, the stop 15 has a projection with respect to the limiting leg 7a, respectively, flush with it. An overhang of the stop 15 is realized in the inspection frame 1, whereas the stop 15 is flush with the limiting leg 7a at the inspection cover 2. This is why, so as not to jeopardize the installation or removal of the inspection cover 2 in the inspection frame 1 respectively pivot movements of the inspection cover 2 relative to the inspection frame 1 to allow a hinge, not shown.

Finally, it can be seen that both the fastening means 7a, 7b and the cover and / or frame extension component 10, 11 are arranged behind a viewing surface 14 in a plan view of the inspection device. In fact, the fastening means 7a, 7b are each in the rearward extension of the frame profile 5 and the cover profile 6. The insulation board 10 and the insulating strips 11 can be found in each case at the back of the standard paneling 3.

In the context of the invention, the inspection frame 1, the inspection cover 2 which can be inserted therein and the one or more attachment means 7a, 7b form a structural unit 1, 2, 7a, 7b as a whole. This unit 1, 2, 7a, 7b is equipped with the help of the standard planking 3 at the installation site or has this standard planking 3 already. Then, the assembly 1, 2, 7a, 7b expanded as it were to the standard planking 3 and is a structural unit 1, 2, 3, 7a, 7b before. This assembly 1, 2, 3, 7a, 7b from revision frame 1, inspection cover 2, fasteners 7a, 7b and Standardbeplankung 3 is now - as described - to the present at the installation site building physical Requirements, e.g. B. a particular band protection class adapted, in which, as needed, the cover - and / or frame extension component 10, 11 added. It is understood that the fastening means 7a, 7b can basically be available as a separate element and with the inspection frame 1 and the inspection cover 2, for example, also a releasable connection received.

That is, the attachment means 7a, 7b and the associated revision frame 1 and the inspection cover 2 can be releasably connected to each other or connect to the assembly 1, 2, 3, 7a, 7b in connection with the standard planking 3 only at the installation site. It follows that the fastening means 7a, 7b can in principle also be sold and stored separately from the inspection frame 1 and / or the inspection cover 2. In order to achieve an unambiguous assignment of the fastening means 7a, 7b on the one hand to the inspection frame 1 and on the other hand the inspection cover 2, the invention additionally provides that in this case the attachment means 7a, 7b and / or the revision frame 1 and / or the inspection cover 2 with one or more positioning means are equipped. This ensures an unambiguous definition of the respective fastening means 7a, 7b on the inspection frame 1 or the inspection cover 2 in the course of assembly. The one-piece embodiment of fastening means 7a, 7b, realized on the one hand, and inspection frame 1 or inspection cover 2, on the other hand, is therefore to be understood as an example and not by way of limitation.
