Definitions

• the invention relates to an aggregate of revision cover and this receiving base with planking, the revision cover being equipped with a revision frame and an inspection cover which can be inserted into the revision frame, and wherein the revision frame is a peripheral frame profile for receiving a frame frieze formed as an outer frame from one or more Plate strip has.
• the plate strips are generally insulation board strips, ie those that are designed to be fire-resistant. This is not mandatory.
• inspection covers serve to make internals located behind them accessible.
• the inspection cover can be placed in a pre-masonry wall, a ceiling or a double floor.
• the inspection cover directly in, for example, masonry walls, a chimney shaft or the like.
• the inspection coverage meets certain fire protection requirements, which manifest themselves in so-called fire protection classes. For example, for buildings up to two full floors and in open construction partition walls of fire protection class F30 are sufficient. Buildings with more than two full floors require class F90 fire-resistant partitions.
• ceilings of class F30 are usually required for buildings with more than two full floors (see Paul Diem "Building Physics in Context", 2nd edition, Bauverlag GmbH, 1996, page 256 ff.).
• the inspection cover usually has, in addition to the inspection frame, also a peripheral frame profile for receiving insulation boards.
• the insulation boards of the inspection cover are like the insulation board strip of the outer frame or frame frieze adapted to the required fire resistance. The same applies to any gaskets.
• the strength of the frame frieze for the representation of the outer frame is adapted to the strength of an adjacent planking of the fire protection structure.
• a separate and specially prepared inspection cover must be provided for each planking thickness of the fire protection structure. This leads to increased production and storage costs and increases the effort when installing the inspection cover on a construction site, because different fire protection structures to accommodate the revision cover also require different inspection covers.
• DE 202 10 787 U1 deals with a security door, in particular fire door for fireproof and / or smoke-tight separation of an introduced into a wall opening.
• a fire-resistant and / or smoke-tight compensating element which surrounds the associated opening in the manner of a frame or is fitted in the opening is optionally provided.
• the invention is based on the technical problem of such an aggregate of inspection cover and receiving base with planking so wide. that as few audit coverage types as possible have to be used and that these can be easily adapted to local requirements.
• a generic unit in the invention is characterized in that at least one spacer strip is provided which bridges a space between the base and the frame frieze remaining space, if necessary, to access one and the same revision cover with varying thickness of the planking ,
• the base is generally the existing fire protection structure into which the inspection cover is inserted.
• this fire protection construction it may not be limiting to a stand, which is mounted ceiling, wall and / or bottom side in or on a building and, for example, has a planking of refractory insulation boards.
• the inspection cover will usually be placed in this fire protection structure at the point where installations need to be made accessible for maintenance.
• the inspection cover is usually hinged mounted in the inspection frame and can be locked in the inspection frame. This can z. B. a latching closure may be provided, but this is not mandatory.
• the invention In order to cover the fire protection classes described above in a building, the invention ideally only relies on a single inspection cover or in any case a smaller number of inspection covers compared to the previous one. Any deviations of the strength of the outer frame or frame frieze from the mostly provided planking of the the inspection cover receiving fire protection structure are compensated by the at least one spacer strip. As a result, one and the same inspection cover, including inspection frame and frame frieze, can virtually always be used from one or more strips of insulating board, without a distinction having to be made or made according to different fire protection classes. Nevertheless, to adapt the outer frame in terms of its strength to the thickness of the planking of the fire protection structure, the one or more spacer strips are provided.
• the spacer strip may be formed as a closed frame. But it is also possible to provide a plurality of spacer strips which form a closed frame. Moreover, it is of course within the scope of the invention to mount a plurality of spacer strips on top of each other, if this requires the size of the remaining space between the base or the framework and the frame frieze. In addition, the use of the spacer strips is to be regarded as an option, namely, if there is even a gap between the base or the framework and the frame frieze.
• the respective Revision cover In order to provide at this point for the necessary compensation and the bridging of the gap between the base and frame frieze, the respective Revision cover usually offered as a complete sales set with revision frame, inspection cover and several spacer strips.
• the frame frieze usually has a thickness of 12.5 mm for the fire protection class F30, while the fire protection class F90 has a thickness of 25 mm.
• the one or more spacer strips are provided.
• the respective spacer strip is made of a fire-resistant insulating material.
• plasterboard, silicate boards or the like can be prepared from aluminum and / or calcium silicates plus, if appropriate, binders.

• a connecting device for fixing the spacer strip to the base and / or to the frame frieze is provided.
• this connecting device is an adhesive agent layer applied on one side to the spacer strip on the one hand, which ensures a pre-assembly of the spacer strip on the frame frieze, as it were.
• the connecting device is designed as the frame frieze and the spacer strip by cross-fastening means.
• the penetrating fastening means is generally suitable for final assembly and is embodied, for example, as the frame frieze and the spacer strip by means of a comprehensive fastening screw.
• the fastening screw or the fastening means is additionally anchored in the base or in the stud work and ensures that the frame frieze and consequently the outer frame of the inspection cover learns the required fixation with respect to the base or the stud work.
• the fastener for final assembly can be reliably introduced, it has proved to be advantageous if the frame frieze has at least one mark for attaching the frame frieze and the spacer strip by cross-fastener. This mark may be a color mark, a notch or the like.
• the encircling frame profile is formed in cross-section T-shaped with resting on a T-leg base side inner frame. In contrast, there is between the T-leg and the T-bar of the peripheral frame profile of the frame frieze and consequently the outer frame thus placed.
• the inspection cover on the outside - may be equipped with a fire seal - facing the encircling frame profile.
• This can be designed as a hollow chamber profile.
• the fire seal acts together with an opposing arranged in the frame profile inflatable seal. Both seals ensure that a gap remaining between the inspection cover and the surrounding frame profile is closed in case of fire.
• the procedure is that the spacer strip laid on the frame frieze defines, together with it, a common outer edge surface, to which the planking of the fire protection structure immediately adjoins.
• the common outer edge surface may also rest against an opening in a masonry.
• a novel inspection cover is provided, which is standardized and - regardless of the required fire protection class for installation - relies on one and the same revision frame and a single inspection cover.
