Description

Building board, in particular for ceiling mounting, as well as methods for opening or closing a revision opening in a building board

description

The invention relates to a building board, in particular for ceiling mounting

Claim 1, a Bauplattenset according to claim 13 and a method for opening and closing a revision opening in a building board, in particular gypsum board, according to claim 14.

In the prior art, for example from DE 202 10 036 Ul, are

Inspection flaps especially known for suspended ceilings or walls, with which it is possible to provide access to electrical or plumbing installations, if necessary, which are located under the ceiling or wall. For inspection work, in particular repair, service or conversion work, the access door can be opened so that access to the electrical or plumbing installations is made possible via a corresponding inspection opening. The inspection flaps according to the prior art are usually held in a frame and with respect to this opening or closing via hinges

pivotable. The inspection opening itself is made at the construction site by sawing, and then the frame is used for receiving the access door in the sawed opening.

The revision devices known from the prior art are perceived as relatively complicated with regard to their construction and assembly. The invention is based on the object to propose a ceiling element with a closable inspection opening, the manufacturing and

Design effort compared to the prior art should be reduced. This object is achieved by a building board, in particular gypsum board, according to claim 1, a Bauplattenset according to claim 13 or a method according to claim 14.

The object is in particular by a building board, in particular for

Ceiling assembly solved, comprising a base body with at least one manufacturer provided for inspection opening for performing

Inspection work, such as repair and / or assembly work and the like, at least one holding device and at least one plate-shaped

Inspection cover for closing the inspection opening, which can be suspended by means of the at least one holding device in the base body and in the suspended state by turning by a predetermined angle of rotation and subsequent tilting by a predetermined tilt angle from the inspection opening can be suspended. The building board, the base body and the inspection cover have a front side and a rear side, wherein the following is meant by "front side" that the corresponding side faces away from the installation devices or faces the room in the installed state "the side to be understood, which faces away from the room when installed or facing the installations. The building board, the

The base body and / or the inspection cover may in particular consist of gypsum and / or gypsum fiber material (at least partially).

A core idea of the invention is that the inspection cover for

Closing the inspection opening can be hung in the base body, the inspection opening and the inspection cover are already matched to each other manufacturer such that an opening of the inspection opening by turning and subsequent tilting can be done comparatively easily. According to an even more general idea, opening through the geometry (for example a rectangle with or without corner rounding) is thus made possible. This eliminates the time-consuming sawing of the inspection opening at the construction site and the mounting of a frame for receiving the inspection cover. In addition, characterized in that the opening is carried out essentially by turning the inspection cover, up and down only little space for performing the opening operation is necessary. Overall will be the manufacturing and construction costs compared to the prior art reduced.

The structural panel may be formed such that the inspection cover of the other components by a translational movement, during or after the

Tilting can be removed. The building board can also be designed such that the rotation of the inspection cover a translational movement (at least component-wise) must be superimposed in the direction of the back of the building board. The lifting of the inspection cover can be done before, during or after turning or tilting or the building board be designed.

In preferred embodiments, the inspection opening and / or the

Inspection cover (substantially) rectangular, preferably with rounded corners, more preferably with a corner radius of 5 mm to 100 mm, even more preferably from 30 mm to 70 mm and / or oval, in particular elliptical. In general, the inspection cover can also be polygonal. The

Corresponding corners are preferably rounded. In the elliptic embodiment, a ratio of one long to one short axis is preferably at least 1, 1, more preferably at least 1.5, even more preferably at least 2. Other shapes in which the extent in a longitudinal direction is greater than the extent in one Transverse to the longitudinal direction, are possible in principle.

For example, in the case of a rectangular design, only a small height of the inspection opening must be maintained compared to other ceiling components.

The angle of rotation preferably has at least 1 degree, more preferably at least 10 degrees, more preferably at least 30 degrees, still further

preferably at least 70 degrees and / or preferably at most 179 degrees, more preferably at most 170 degrees, even more preferably at most 150 degrees, even more preferably at most 110 degrees, in particular (approximately) 90 degrees. The angle of rotation is preferably less than 45 degrees, more preferably less than 15 degrees, even more preferably less than 5 degrees, even more preferably less than 2 degrees. Such a design of the building board, the opening and closing of the inspection opening particularly simple, even without a particularly large margin must be up or down, performed.

The inspection cover has in a preferred embodiment, on its side facing the base body side edges or circumferentially one Revision cover fold on, with a correspondingly formed

Grundkörperfalz is engageable with the body, so that the

Inspection cover solely due to the corresponding folding alignments of

Inspection cover fold and Grundkörperfalz can be kept in the body.

Of course, it is possible that even further measures can act in addition or alternatively to keep the inspection cover in the body.

In a preferred embodiment, the building board at the back

at least one, in particular prepared by the manufacturer, preferably frame-shaped, spacers, such that the building board is at least partially coverable at its rear side with at least one spaced apart from the inspection cover cover plate. This allows the sound and

Fire protection properties of the ceiling can be easily improved. By the spacing of the cover plate and inspection cover are the

Improved fire protection properties and also created a volume in which sound can be absorbed.

Preferably, the building board at its rear side, in particular manufacturer provided, preferably frame-shaped, positioning element, such that the building board / the inspection cover at its / its back by at least one / the cover plate in a predetermined position relative to the building board /

Inspection cover, preferably this touching, can be covered. Spacer and position element may form a unit or be present as separate elements. A position element makes it possible to securely provide the cover plate over the building board or the revision ceiling, so that the fire protection improved and a dirt entry through the inspection opening is reduced.

The cover plate may represent an external component or be part of the building board and in particular be prepared by the manufacturer. The cover plate is preferably formed to the back of the building board and / or the

Inspection cover, in particular at least partially cover a joint between the body and the inspection cover. Such a cover plate of the fire or sound insulation can be improved and a dirt entry through the inspection opening can be reduced. Preferably, the holding device has at least one fold. The fold can be provided on the inspection cover and / or the base body. As a result, a suspension and thus a handling of the building board can be done very easily.

In concrete developments, the inspection cover at least one

Peripheral device, such as at least components of a lighting device and / or a transformer and / or a fire alarm and / or a loudspeaker include. The peripheral devices can be particularly easily assembled or dismantled. The building board is constructed in a constructively simple way versatile.

Preferably, the building board and / or the base body and / or the

Inspection cover at least partially made of metal, more preferably at least partially formed as a diamond plate or as a special gypsum board and / or partially by a solidifying agent, such as polyurethane and / or silicate or dg I. , solidified. The wear by the opening and closing is so low, which increases the life.

An alternative or additional way to protect the inspection cover and in particular the revision cover fold is the back cover, that is connected at its rear still connected to a rear plate, said rear plate at least partially, preferably over the entire circumference surmounted the inspection cover, ie in so far one

Supernatant is given. The supernatant protects the inspection cover, in particular the inspection cover fold from damage, then, for example, when the provided with the rear plate inspection cover is placed on a floor.

Preferably, at least one joint between the inspection cover and the base body is sealed or sealable by a sealing means prepared in particular by the manufacturer, in particular a sealing strip. It may also be provided sealing means between different cover plates or one or more cover plates and the inspection cover and / or body. The fire and

Soundproofing is thereby improved. Furthermore, a dirt entry is reduced. A sealing tape is a structurally particularly simple way to

Seal. The above object is achieved by a construction set comprising a plurality of structural panels, at least one of which is formed according to the above-described type. Several structural panels may have the same basic shape, for example, the same length and width, with only a subset, for example, one, is equipped with a revision option according to the above-described type. At the construction site, the inspection opening can then be placed particularly quickly and easily.

The above object is further achieved by a method for opening and closing a revision opening in a building board, in particular the

above-described type, preferably for a Bauplattenset of the type described above, wherein the manufacturer side at least one base body with at least one inspection opening and a revision cover are prepared, the

Inspection cover is brought to close the inspection opening in a predetermined first position, wherein the inspection cover is brought to open the inspection opening by twisting, lifting and tilting in a second position in which it by a translational movement through the inspection opening

can be passed. Such a method requires only a small design effort and is relatively easy to perform. The

translational movement through the inspection opening may be performed during tilting or after.

All edges, in particular folded edges, can each be beveled or rounded.

The lifting is preferably carried out by at least the thickness of the inspection cover, but may also be smaller depending on the design of the body.

Preferably, the lifting is at least 1 cm, more preferably at least 2 cm, even more preferably at least 4 cm. The lid may have the same dimensions or different dimensions.

The invention will also be described in terms of further features and advantages with reference to an embodiment which is explained in more detail with reference to the figures.

and

Fig. 5 is a sectional view for illustrating a further modified

Embodiment.

Fig. 1, Fig. 2 and Fig. 4 illustrate an embodiment in which a building board with a base body 10, a revision cover 11, a first

Cover plate 12, a second cover plate 13 and a frame-shaped

Spacer 14. The building board is designed as a gypsum board, such as plasterboard.

The inspection cover 11 has a revision cover fold 15 at its edge and can be suspended in the main body 10 or a Grundkörperfalz 16 of the base body 10, so that an inspection opening 17 is closed. Of the

Grundkörperfalz 16 extends at the edge of the inspection opening 17th

Inspection cover 11 and the corresponding inspection opening 17 are formed as rectangles (in a view of a back or front) and spatially cuboid. If the inspection cover 11, when it is mounted in the inspection opening 17, slightly raised and rotated by a predetermined angle, for example 90 degrees, and then tilted, it can be passed through the inspection opening 17 and thus removed. Optionally, at the same time take place during the twisting and / or tilting and / or lifting a translational movement, for example, in a preferred plane defined by the building board.

On the frame-shaped spacer 14, the cover plates 12, 13 are placed so that a cavity 18 between the base body 10 and

Inspection cover 11 on one side and the cover plate or the cover plates 12, 13 can be made on the other side. The cover plates 12, 13 may also be matched to the spacer 14 so that they can be positioned within the frame-shaped spacer 14 and thus can be placed directly on the base body 10 and / or the inspection cover 11.

The cover plates 12, 13 are also rectangular in shape, but may also be square or have any other shape. Several cover plates 12, 13 can be arranged next to and / or above one another. The cover plates are preferably designed such that they pass through

Twisting and tilting analogous to the inspection cover 11 through the inspection opening 17 can be passed. The spacer 14 has (approximately) a threefold thickness relative to the inspection cover 11 or a base plate 19 of the base body 10. The spacer 14 is constructed here, for example, twelve strips, each of which are three superimposed and form a total of a rectangular configuration. It goes without saying that the spacer can also be designed in any other way and in the training

For example, instead of a three-layer construction, a two- or four-layer structure can be taken into consideration.

If the inspection lid 11 is located inside the inspection opening 17, then the building board can be filled over at its front side and / or over-wallpapered, so that the inspection lid 11 is not visible. Are then still revision work

necessary, the inspection opening 17 can nevertheless be achieved comparatively easily.

FIGS. 3 and 5 show again modified embodiments of the present invention. In Fig. 3 is a on a Revisionsdeckelfalz 15 to a Grundkörperfalz 16 of the body 10 engaging the inspection cover 11 in

Sectional view illustrated. The inspection cover 11 is held only in the base body 10 by way of the surface sections of the base body fold 16 facing the direction of the gravitational force.

In Fig. 5, the inspection cover 11 deviating from the embodiment of FIG. 3 nor a rear plate 20 which is connected to the inspection cover 11, for example glued. The rear plate 20 is in the present embodiment circumferentially opposite the inspection cover 11 via a

given supernatant 21 about, so that, should the inspection cover with in it fastened rear plate 20, for example, be converted, the inspection cover 11, in particular the inspection cover fold 15 is protected.

In the embodiment of FIG. 5, the inspection cover 11 by the supernatant 21 of the rear plate 20 in the base body 10 and / or through the

Revision cover fold 15 in cooperation with the Grundkörperfalz 16 im

Main body 10 to be held.

The building board may be formed as a perforated plate or holes with a

predetermined geometry, for example, with a round or rectangular cross-section, have. Such holes improve the sound properties of the building board.

It should be noted at this point that all the above-described parts taken alone and in any combination, in particular the details shown in the drawings, are claimed as essential to the invention. Variations thereof are familiar to the person skilled in the art.
