Abstract

Production and process of a double-sided fire-resistant, insulating, sound-absorbent fire-compartment panel for walls and ceilings, and for cable partitioning, with the use of hot-dip galvanised general purpose mounts in the interior fitting and protection in buildings of all kinds, and for factory buildings and industrial buildings, schools, kindergarten buildings, clinics, administration buildings, etc. These form protection: of heat insulation against fire - flames and hot vapours which have to be held in check for at least 90 minutes in order to save valuable lives - and, within a time span of 90 minutes so that the fire brigade has sufficient time to carry out all rescue attempts within a reasonable time. An even more important point is that the system panel is particularly serviceable as heat insulation against the effect of cold and as sound protection; in this regard we envisage saving of energy costs etc. And particularly critical areas may also be screened off using the panel as a wall and in the process made habitable. This panel will also be indispensable as an insulation panel in residential construction, but at the same time also serves as a fireproofing and sound-absorbent panel. Various possible applications are combined in one system. This panel is simply universal and meets all its demands.

Description

This is a new invention, namely a double-sided fire, insulation, fire insulation and sound absorption plate with the use of hot-dip galvanized general-purpose brackets for pressed mineral fiber products. (Plates) The mineral fiber (rock wool) is pressed in several layers by a machine and created to a thickness of 25 mm.A protrusion of approx. 2.5 mm must be pressed in on each plate ( Fig. 1-4, 4a, 5) Fig. 2/3/4/5 and 6 show different possibilities.

The special thing about the invention is that the plate can be created as a double wall and by both Sides has the same function as fire protection and fire insulation also in double on the ceilings function can occur.

A further development is that a 1.5-3 mm color insulation layer is applied on both sides, as an insulation layer former, this layer foams, at approx. 150 ° C and keeps a heat of 1000 ° C, for about 90 minutes - continuously (F 90 ) Fire safety.

During the development it was thought to bring in a hot-dip galvanized sheet steel bracket. This results in a simple application; through a groove 7 in the around the entire plate, it is possible to introduce a steel belt system 13 which is connected to the lower rail 16 and the upper rail 17 . The protruding triangular tips 14 , 15 are fitted into the sides of the plates 7 and pressed in so that the mineral products are fully preserved, these must not be damaged.

The same applies to the installation of the ceiling panels, since there is a bracket where the hanging rail Fig. 9-26a is hung in the rail 13 , the rail is directed in the profile of the perforations of punched triangles so that the tips are inserted horizontally into the Moves the sides of the plates and cannot damage anything.

Now you have the possibility with the system - to remove walls and ceilings with these panels at the same time.

The vapor barrier is very generous 5, 6 2.5 mm on both sides, in the middle is the aluminum reflector film that is mutually beneficial.

A further advantage lies particularly in marketing, since cross-ventilation is possible through the holder 13 , which is provided with center holes.

Half of the cost is reduced by this plate compared to the competition, because in the past 2 plates at least had to be installed - to achieve F 90.

On the walls you have the possibility of great colors and Attach plaster structures. There are also others Apply paint coats over the entire surface.

The Her is versatile the position price drops significantly as mass is produced can be.

Almost all hotels, schools, kindergartens, administrative offices, Industrial buildings etc. are now safer with this System. Because not only one side is protected, but because a lot of interior space is also saved.

It will definitely take some time to find a replacement product to develop.  

An additional heat protection shield is created by coating both sides of 1.5 - 3 mm of paint on the mineral fiber / rock wool surface 3 , 3 a . Because with a heat of 150 ° C the dye on the surface 3 , 3 a swells up to 5 cm, 1000 ° C with a DIN value F 90 are reached. The use of walls and partitions of cables is thus achieved, since only one plate A 1 is used here.

Saving material compared to the competition. Now walls and ceilings in buildings can be used here: hospitals, Residential and administrative buildings, industrial buildings of all kinds  are protected against fire protection in fire class F 90.

The double-sided plate with a thickness of 60 mm is sufficient now out to important points even with cable transfers in and on wall openings.

After its completion, the double-sided fire-insulating bulkhead sound absorbing composite panel for walls and ceilings consists of approximately 2 x 25 mm thick panel elements 1 , 1 a consisting of mineral fiber wool, rock wool.

In addition to the 25 mm single panel, a profile 4 , 5 , 6 , the inner panels of 2.5 cm cavity, with two panels of 5 cm total is created. This cavity serves a) as a vapor barrier, b) as ventilation, c) as sound absorption and through the film in the middle, as a double-sided effect.

The reflector film of aluminum 2 mm has a thickness of up to about 5/100. The layer of glue is about 45/100 to about 1 mm, the application of the glue can never be determined exactly. The glue layer is applied point by point from both sides to the protruding protrusions of the mineral fiberboard inner sides 4 a , 4 b and pressed together with the aluminum reflecting film located in the center.

After these processes, the double plate receives a two side painting with a foaming agent up to 2.5 mm per side is applied. Insulators up to 3.5 to 5 cm in thickness swell from 150 ° C and also holds up to 1000 ° C heat.

This achieves a total plate thickness of 60 mm.

The surface of the panels for walls and ceilings can be provided with a structure color choice. With walls it even serves double-sided.

Plastic is not introduced into this system, as well Wood and other - easily flammable substances.
