for serving Bi and the like of components, in particular fires, against the passage of smoke and flames.

In the case of flammable components and those that are flammable, but are fire-proof, or in the case of non-flammable construction elements there are joints, cracks or gaps, e.g. the door gap on doors between the door and the door frame, in the event of a fire, the weakest parts, because this is where the flames or the ß also most likely to penetrate *

Bs is known to remedy this disadvantage by e.g. in the case of doors, grooves are provided in the door stop or door frame, in which a chemical paste that foams when heated is painted or injected, which, because of its consistency, in the hat or the like. by covering with some material, e.g. with easily tangible plastic sheeting, must be secured. But even with pastes protected from flowing out in this way, it is difficult to prevent them from becoming with the Push it together and sag downwards. Also lose this fasting with the ^ time moisture, what changes in volume conditional, so that they then fall out of the grooves or theirs The introduction of such pastes also makes difficulties because it can only be done by brushing or spraying

is possible, which makes it difficult to obtain the correct dosage in terms of quantity Another disadvantage is that with components from wood with the paste moisture gets into the dry wooden elements, which causes swelling and possibly throwing these parts can result, whereby the dimensional accuracy, e.g. for doors, is adversely affected.

The innovation avoids the broad outlines given above Power.

It differs from the previously known designs Above all by a solid sealing body, which is made of a paste-like, chemical, foam-forming when heated Fire protection mass of existing composite bodies solidified by drying formed with one or more stabilizer intermediate layers and within wide limits of elasticity and breaking strength is.

As a stabilizer intermediate layers in the sense of the innovation in particular glass non-woven, fine-meshed fabric from d ^r U nnem wire mesh, etc. can be used..

The main advantage of the innovation is that the Sealing body has elasticity and breaking strength within wide limits and can also be laid in grooves, which are more or less curved. A release of moisture on dry wooden parts, as when using basting as a sealant, does not take place «So they are out of it resulting and the other disadvantages of the load seal mentioned above are avoided.

The solid sealing bodies can be colored according to the innovation. For this purpose , colored fire protection pastes can be used. This makes it possible to produce solid composite sealing bodies of any color, which can be important for identification a fire-safe or fire-retardant color.

Furthermore, the finished sealing bodies can be protected against moisture with an incombustible, moisture-repellent agent, for example a colorless lacquer based on Ghlof rubber. The production of the sealing body after the heating is advantageously carried out in such a way that a paste-like chemical fire protection agent known per se, which foam-forming when heated, is applied or spread on a suitable base, an stabilization layer or sheet made of an incombustible material, in particular glass fleece, is applied to it Refractory thin fabric made of, for example, close-meshed wire or the like, placed over this another layer of the chemical paste-like η material and this process is repeated until the desired thickness and number of intermediate stabilizer layers is reached, whereupon the composite body thus formed is dried , lifted from the base and used unassembled or disassembled into different parts for sealing. In the drawing, an exemplary embodiment of a sealing strip or sealing body designed according to the invention is shown schematically.

In the example, the sealing body consists of three layers 1, 2, 3 of paste-like, chemical material that forms foam when heated and the intermediate stabilizer layers 4, 5 made of glass fleece, fine-meshed, thin wire mesh or another incombustible material. Instead of the three layers shown with intermediate layers, you can the sealing body also consist of more or fewer layers and intermediate layers. According to the example, layer 1 is first applied to a suitable one Base, not shown, applied, in particular painted on. Then the stabilizer intermediate layer 4 is placed on top. The pasty intermediate layer 2 is applied to this, The stabilizer intermediate layer 5 is placed on top of this and on top of it the cover layer 3 from the pgsicenf örmigen mass coated on ge. The composite body thus formed is then solidified by drying and then removed from the base. It is now finished and can, depending on the needs, be broken down into individual pieces are used, e.g. by sawing, etc., or they are used whole This depends on the size of the sealing body and the size of the seal the joint to be sealed or the like.
