Description

Roller shutter box.

The innovation concerns a roller shutter box. It is there in particular thought of a so-called roller shutter lintel box, on which the door or the Lintel is put on or concreted on.

Today there are roller shutter lintel boxes of the most varied designs on the market. A wide variety of materials are used in these constructions · TJm only the most important to name materials already used, it should be noted that there are roller shutter lintel boxes made of sheet metal, made of steel profiles, lightweight panels, chipboard, wood and styrofoam as well as aluminum profiles have been.

On the one hand, the corrosion resistance of these roller shutter boxes, which have been on the market up to now, leaves a lot to be desired, on the other hand, these constructions are

and thermal insulation extremely poor. Another disadvantage this known roller shutter boxes is seen in the fact that they are not used as an immediate plaster base in many cases can be, so that you still have to provide special constructions, namely the attachment of special plates to such to plaster a room provided with a roller shutter box "

Finally, a roller shutter box is also known that is marked is through a skeleton made of ribbed expanded metal, especially in the side bars, which is made with rigid foam made of Styrofoam is filled with foam »

Such a roller shutter box again has the disadvantage that it is relatively expensive because this is evident from the used Construction materials results.

The object of the innovation is to provide a roller shutter box, in particular a roller shutter lintel box, which has the disadvantages the known roller shutter boxes does not have. It will be there from a likewise known roller shutter box made of concrete, however, it is proposed according to the innovation, this roller shutter box made from aerated concrete.

This known material has the advantage of good heat and sound insulation properties; it is weather resistant and at the same time a good plaster base. Another advantage of aerated concrete can be seen in the fact that it is good in terms of production technology can be processed.

5 3 It

It is particularly recommended to use aerated concrete made with a propellant that is neutral with regard to possible corrosion _{or the like}

A gas concrete has proven to be particularly advantageous Composition results from the addition of the propellant "Adicon" available on the market. With the addition of this propellant the result is aerated concrete that is particularly suitable for use as a building material for a roller shutter lintel box

A further development of the innovation can be found in the lower edges The roller shutter aprons are provided with edge protection made of a corrosion-resistant material, e.g. aluminum.

An embodiment of the innovation is shown in the drawing, The drawing shows such a roller shutter box installed, i.e. inserted into the masonry.

The actual box is denoted by 1 in the drawing. For the purpose of reinforcement, a structural steel mesh 2 is embedded in the box, which has a U-shaped shape adapted to the profile of the roller shutter box, i.e. such a welded wire mesh, whose Cross bars are designated by 3, is bent accordingly and expediently in a holding device of the edge protection strips 4 hooked, which form the lower edges of the side aprons 10 of the roller shutter box 1 »By the clamping effect, the Reinforced steel mesh at both ends in these edge protection strips

hung so that the aerated concrete is then filled into the mold can be. At the same time are in the upper part of the shutter box 1 support bracket 6 is used, which also serve as an anchor bracket for the lintel 8 to be concreted. The reinforcement the lintel 8 to be placed is marked 9 in the drawing · The subject of the innovation is only the roller shutter box 1 "

As can also be seen from the first drawing, the edge protection is laterally somewhat extended so that it also serves to anchor the plaster 11 »

The drawing shows the drum 7 for the roller shutter, which, however, is not part of the innovation.
