Box element for construction purposes

The innovation relates to a box element for building purposes according to the generic term of protection claim 1.

In the sense of the innovation, a "box element for building purposes" is, for example, a component in the form of a roller shutter box or an element which serves to accommodate an external blind, but can also be used as a window and door lintel.

The aim of the innovation is to show a box element that can be used either as a roller shutter box or as an element for accommodating an external blind. To solve this problem, a box element is designed in accordance with claim 1.

Further developments of the innovation are the subject of the subclaims. The innovation is explained in more detail below using the figures for an exemplary embodiment. They show:

Fig. 1 shows a simplified representation and in section of a box element according to the innovation for the optional accommodation of an external blind or a roller shutter, in a state suitable for receiving an external blind;

Fig. 2 is a view similar to Figure 1, but in a condition suitable for accommodating a roller shutter.

In the figures, 1 is generally a box element which is made of a heat and sound insulating material, for example expanded clay particles with a suitable binding agent, for example in the form of a rigid plastic foam and possibly with other additives and which, when used, for example in

Area of an external building wall above a window or door opening as a window or door lintel.

In the embodiment shown, the outer surface of the molded body 2 of the box element 1 is essentially designed as an elongated cuboid, with a top side 3, an outer side 4 which is located on the outside of the building after installation, an inner side 5 which faces the inside of the building after installation and a bottom side 6. The sides 3, 4, 5 and 6 adjoin one another at right angles. Close to the outer side 4, the molded body 2 is provided with a recess 7 which is rectangular in cross section and which extends over the entire length of the molded body 2 or the box element 1 and is open towards the bottom side 6. In the area between the recess 7 and the inner side 5, the molded body 2 is provided with a further recess 8 which, in the embodiment shown, is a rectangular recess which is closed all the way around. The recess 8 has a height H in the axis perpendicular to the top side 3 or bottom side 6 such that the upper side 8' of the recess 8, which runs parallel to the top side 3, is at the same level or approximately at the same level as the top side 7' of the recess 7, which also runs parallel to the top side 3, and the recess 8 extends from the side 8' over the greater part of the height of the recess 7. The upper side 8', which runs parallel to the top side 3, has a distance al from the top side 3. The bottom side 8" of the recess 8, which also runs parallel to the top side 3, ends at a distance a2 which is equal to the distance al.

The recess 8, which also extends over the entire length of the molded body 2, is filled with an insert 9 made of a heat-insulating and possibly also sound-insulating material, for example with a foamed plastic, e.g. Styrofoam, wherein the production takes place, for example, in such a way that the insert 9 is inserted as a molded body into the mold used to produce the molded body 2 and the molded body 2 is then formed around this insert 9.

In the state shown in Figure 1 (for use in an external blind), an insulating body 10 made of heat-insulating material and inserted into the recess 7 is held in a suitable manner, for example by gluing, on the inner surface 7" of the recess 7 adjacent to the recess 8 and running perpendicular to the upper side 3 or lower side 6. The insulating body 10, which is designed in strip form with a rectangular cross-section, consists for example of a suitable plastic rigid foam and extends over the entire height of the recess 7, i.e. from the upper inner surface 7' to the open side of the recess 7 or to the level of the underside 6. The insulating body 10 is designed in such a way that between the side of the insulating body 10 facing away from the inner surface 7" and also arranged perpendicular to the upper side 3 and the opposite inner side 7'" of the recess 7 adjacent to the outer side 4, there remains a sufficiently wide space which is sufficient to accommodate the opened external blind, i.e. its elements.

The insulating body 10 achieves high thermal and sound insulation values between the outer side 4 and the inner side 5, despite the relatively wide opening formed by the recess 7 on the underside 6 of the box element 1 in this application.

Figure 2 shows the use of the box element 1 as a roller shutter box. For this purpose, the element 11 is inserted into the recess 7 instead of the insulating body 10. This element is also made of the heat-insulating material, for example of a suitable plastic rigid foam, and closes off the recess 7 on the underside 6 except for an opening slot 12 that is much narrower than the width of the recess. The element 11, which in turn is attached to the inside 7" in a suitable manner, for example by gluing, is shaped in such a way that it extends from the underside 6 over a certain height of the inside 7", namely over a height that is greater than the distance a2, so that the element 11 and the insert 9 overlap. With the underside facing away from the recess 7, the element 11 lies in a common plane with the underside 6.

With the element 11, the space used to accommodate the rolled-up roller shutter curtain and formed by the recess 7, in which the roller shutter shaft and other functional elements are then arranged, is not only sealed off from the outside of the building except for the narrow opening slot 12, but the element 11 also acts as a heat and sound insulation due to its arrangement overlapping with the insert 9, so that high heat and sound insulation values are also achieved with this application of the innovative box element.

In the embodiment shown, the box element 1 has a width of 380 units on the top 3 and bottom 6 and a height of 300 units on the sides 4 and 5, the total height of the recess 7 being 250 units and the total width of this recess being 180 units. The height H of the recess 8 is 200 units and the width B of this recess is 90 units, the recess 8 being at the same distance a3 and a4 from the inner surface 7" and from the inner side 5, namely 40 units, and the thickness of the insulating body 10 measured in an axial direction perpendicular to the inner surface 7" is 50 units. One unit is, for example, 1 mm.

The box element 1 is characterized by a small cross-section and yet offers sufficient space to accommodate a roller shutter curtain of an open roller shutter while providing good thermal and sound insulation.

The innovation has been described above using an exemplary embodiment. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the innovation.
