Abstract

Structural member for the erection of cooling and preserving cells, but also for installing wet rooms, such as bathrooms, toilets or the like, consisting of a hollow body (2) which is flat-rectangular in cross-section and equipped with support and/or thermal insulation elements arranged on the inside and the walls (1) of which are formed from thin sheet metal or plastic plates and which is designed so as to be joinable together with other identically designed hollow bodies, the two walls (1) of each element being prolonged beyond the plane (E), in which the butt joint (5) of adjacent structural members extends and the two prolongations (9) overlapping the edges (8) of the walls (1) of the adjacent structural member. According to the invention, the side edges (3) of the hollow body (2), which are designed so as to be joinable together, on and/or in one another, with the complementarily designed side edges (3) of a corresponding structural member, are provided at least on their contact surfaces (F) with a flocking layer (4) made of relatively short plastic fibres. A joint seal between such structural members can thus be achieved in a simple manner and the mounting of sealing strips and the expenditure associated therewith can be eliminated. <IMAGE>

Description

The invention relates to a component for the creation of so-called cooling and freshness-keeping cells but also for exhibiting wet rooms, such as bathrooms, toilets or the like, according to the preamble of claim 1.

Components of the type mentioned are known, for example, from DE-A-31 40 786, specifically, as mentioned, in particular for the creation of walk-in cooling and freshness cells. Such components can also be considered, in particular, for the renovation of old buildings in wet rooms, in order, as a rule, to make lines laid on the plaster or lines to be laid "disappear" under such components. The exhibition of such rooms with such building elements also made new plastering and tile processing unnecessary.

Such components, as far as is known, which were previously only used in the construction of refrigeration and freshness cells, are filled with CFC-loaded PU foam for thermal insulation reasons, which has excellent thermal insulation properties. For ecological reasons, however, such foams can or should no longer be used, and various proposals have already been made in this regard, but all of them, as far as is known, mean that there is no intimate connection between the thermal insulation and the walls, which otherwise would has ensured that such wall elements do not tend to vibrate or roar. A particular problem is the joint seal between the components, which has so far been taken into account in the creation of cold storage and freshness holding cells by means of sealing strips of suitable material which are to be glued on carefully and thus in a time-consuming manner.

In order to solve the problem of joint sealing between such components in an elegant manner, the object of the invention is to provide such wall elements to train that the demands for simple joint sealing should be taken into account with simple means.

This object is achieved in a component of the type mentioned at the outset according to the invention simply in that the side edges of the hollow body which are formed with the complementary side edges of a corresponding component and are joined together are at least on their contact surfaces with a flocking layer of more or less short Plastic fibers are provided.

As a result, the sealing elements, namely the flocking, become an integral component of the components themselves and, after the wall components have been produced, all the sealing measures which are otherwise to be applied by hand or which have to be observed during the assembly of such cells are dispensed with.

Since the connection edges or side edges of such components have to be flocked anyway for the purpose of joint sealing, an advantageous further development of the components consists in that at least the visible surface of the construction element is also provided with a flocking layer, ie the flocking is not on the connection - or side edges limited, but it covers the entire affected area of the component.

The aforementioned, known sealing strips cannot readily be used for joint seals on the structural or wall elements and wet room equipment, such as bathtubs, sinks, toilet bowls or the like, and one would still be dependent on the use of sprayable, plastic sealing compounds on the one hand, it would have to be installed very neatly and time-consuming, and on the other hand, the colors of the wall elements should never be matched exactly. In addition, such wall components, if you want them as a whole or Use partial exhibition of wet rooms, regardless of whether their walls are made of sheet metal or plastic, have a certain cold touch.

Due to the flocking according to the invention in its further development form, namely as a total flocking, all requirements are met "in one go", ie, the flocking results in a satisfactory deadening effect, special joint sealing measures (regardless of whether between similar, adjacent wall elements or between equipment and the wall element), since the flocking layer to a certain extent engages with that of the neighboring wall element or adapts to the item of equipment, and finally it is achieved that the wall as a whole is more touch-friendly due to the flocking.

"Hollow body" is also to be understood to mean those which are formed only from a wall with bent edges, ie which are open towards the masonry. "Side edges" are also to be understood regardless of their shape, the connecting edges of the wall element, that is, regardless of whether the connecting edges of two adjacent elements are now easy to put together, nested or tongue and groove. The flocking methods are known and do not require any further explanation. By "partial exhibition" of a wet room is to be understood that it can be a component, possibly in combination with only one or two adjacent components, with which only the wall of the room in question is covered, along which pipelines run and on which the equipment must be installed on the room side. "Components" are also understood to mean those which form or are to form floor or ceiling panels or corners of cells or rooms.

In order to allow the equally good and simple sealing due to the flocking according to the invention to come into effect between such components and those which are assigned as wall elements, which also applies to two components which are intended to form a corner of the room, further development forms according to claims 3 and 4 are advantageous provided, which not only guarantee a secure allocation, but thanks to the possibility of being joined together, an optimal seal.

The component according to the invention is explained in more detail below with reference to the drawing of exemplary embodiments.

According to FIG. 1, the component consists of a hollow body 2 which is flat-rectangular in cross-section Q and has internal support and / or heat insulation elements, the walls 1 of which are made of thin sheet metal or Plastic plates are formed, and which is designed to be joined together with other hollow bodies 2 of the same design (see FIGS. 2-5). Not shown are the inner support and / or heat insulation elements and also not the connecting elements (for example turnbuckles) with which adjacent components can be held together or fixed in a suitable manner on the room wall.

For such a component, it is now essential that the side edges 3 of the hollow body 2, which are formed with the complementary side edges 3 of a corresponding component and / or can be joined together, are provided at least on their contact surfaces F with a flocking layer 4 made of more or less short plastic fibers. This is illustrated particularly in FIG. 3, which represents a vertical section through joined ceiling, wall and floor elements D, W, B. The butt joints between these elements are shown enlarged next to them in the associated FIGS. 3A, 3B, 4A.

These sectional representations can also be cuts through a cooling and freshness cell, which is set up as a cube, for example freely in a correspondingly large room, and in which flocking of the inner and outer walls 1 is generally not can be considered.

Examples of possible designs of the side edges 3 are shown in section in FIGS. 2 to 5, which illustrate the manner in which adjacent elements D, W, B can be connected to one another. Since the side edges 3 or the connecting edges are provided with the flocking layer 4, the butt joints 5 are automatically sealed when the elements meet.

Such a seal but also cover also results, as shown schematically in FIG. 7, for the component W equipment items G to be arranged if, as provided in a further development, the large areas of the components are also provided with a flocking layer 4.

Fig. 6 illustrates an embodiment of a wall element W, which is open to the masonry M. Such an element is particularly suitable for receiving and covering, for example, lines which are firmly laid on the masonry. Apart from the fact that with such components according to FIG. 6 an entire interior can be exhibited, it is of course also possible to blend only one wall of a room or a part thereof with one or (depending on the size of the wall components) several wall elements W.

The flocking layer 4 could also be glued to the component as a prefabricated film web, but direct flocking of the walls 1 is preferred, especially since the components generally have a size of at least two square meters, for example, and film webs of corresponding size are produced for this purpose would have to if you want to avoid butt joints between sheets of smaller width. In addition, there would be a risk of coating shifts, particularly when joining wall elements in the sense of FIGS. 2A, B.

Since the butt joints 5 which are produced when components are joined together are very small with respect to their gap width, it is sufficient if the flocking fibers have a length of only 1 to 2 mm, for example.

Because of a precisely fitting connection of the components, side edge configurations which can be plugged into one another are preferred, and also for the connection of the floor elements B and the ceiling elements D to the wall elements W. For this reason, and also in such connection configurations between the floor and ceiling elements B, D one set and the intermediate wall elements W the above To achieve flocking sealing, these floor and ceiling elements B, D according to FIG. 3 or 5 are designed as follows:
The side webs 6 'defining the groove 6' of the floor element filling F are with their outer sheet metal covering 1 'at least by the dimension of the extensions 9 from the floor element level E₂ and the tongue 7 of the ceiling elements W, with the adjacent extensions 9 folded out of the sheet metal covering 1' formed from the ceiling element level E₃ outstanding (see Fig. 5). Correspondingly, the same applies according to FIG. 8 also for a wall element W involved in a corner 10, which is also illustrated in FIG. 5 when the elements D and B are imagined as wall elements W.

Depending on the size, the ceiling and floor elements D, B are designed in one or more parts, taking into account the grid width. If these are in one piece, the groove 6 of the base element B and the tongue 7 of the ceiling element D run around the entire circumference. If these are in several parts (as indicated by dashed lines in FIG. 8 for a base element), the respective central elements B 1, D 1 have grooves or tongues only at their ends.
