Abstract

The system comprises self-supporting panels which have continuous channel-section frame members and are divided into segments by profiled supporting members (4) at right angles to the channel-section members. Each segment is formed by a core layer, and each panel has a covering layer (9) on one or both sides. These layers are of single or composite materials of the necessary density and composition, depending on whether they are to be used for an outside wall, roof or internal partition. The profiled members (4) between adjacent segments have ribs extending towards each other so as to form an intervening space (8) into which filler material is delivered. In the space enclosed by their three sides they have indentations undercut at two sides. Profiled connecting components are fitted between adjacent panels, being suitable for use in a wall or roof as desired.

The invention relates to a composite system for construction purposes with self-supporting Panel elements, especially for use as prefabricated wall or Ceiling elements for buildings, the panel elements being continuous, U-shaped Have frame profiles, the panel elements by angled to the frame profiles arranged, three-sided closed structure profiles in individual Segments are divided and each segment is formed by a core layer is as well as each panel element at least on one side with a top layer is provided.

It is known to quickly build entire walls and ceilings to be processed as finished parts. In the manufacture of such finished parts in the factory these are determined in accordance with the building architecture Specifications produced. Measures related to additional functions such as the installation of door and window openings are already carried out in the factory. Such elements can be inexpensively manufactured in larger series, however, adjustments to size and function of each require Element's relatively complex changes in the manufacturing process.

DE-GM 90 16 771.6 is a self-supporting panel element at the beginning known type known. This self-supporting manufactured in this way Panel elements can be easily sized and sized Adapt function to the respective intended use, however in practice has shown that the panel elements thus produced not for the respective use as a wall or ceiling element are optimally designed, since all of the identically manufactured panel elements are included in the this known building system must be designed so that it is the building walls normal forces occurring as well as those occurring in ceilings Can absorb bending moments. So these board elements are different Use as a wall or ceiling element with respect to one Force or moment component oversized. Beyond that emphasized that the connection of the individual panel elements with each other is very time-consuming and therefore costly because of the individual shock or Contact surfaces bolt connections are necessary.

The invention has for its object to provide a composite system for building with self-supporting panel elements which can produce easily and inexpensively also in small series and individual design in terms of building requirements.

A composite system constructed in this way with self-supporting panel elements can easily in terms of size and function produce adapted to the respective requirements. It is therefore particularly for Production of small series and suitable for an individual construction. priced The individual adjustment of the density is particularly advantageous and / or composition of the core layer of the panel elements depending of the intended use of these panel elements as building exterior wall, Building or apartment partition or ceiling element. On Another cost-reducing advantage is that the composite system according to the invention provided special connection profiles are a simple and quick connection of the individual panel elements enable each other.

By dividing the panel elements into several, each with structural profiles subdivided segments results overall in a load-bearing or stud-like structure Construction by appropriate choice of the number and size of the Segments can be adapted to different requirements. Within of a panel element, the individual segments can perform different functions serve. normally the segments do their primary job as Wall or ceiling parts. In this case there is the core layer of the segments Made of lightweight concrete, with the core layer as a building exterior wall element board element used the lowest density and that of an apartment partition element used panel element has the greatest density. Likewise, any openings for doors, windows can be made in the segments and the like can be arranged.

The self-supporting panel element 1 shown in FIG. 1 is six in total rectangular segments 2 divided. The top and bottom ends of the panel element 1 each form frame profiles 3, which are over all six Extend segments 2 continuously. The frame profiles 3 are, as from FIG. 4 and 6b can be seen as a U-shaped, i.e. side members closed on three sides educated.

The panel element 1 is divided into the individual segments 2 by structure profiles 4, which are arranged at right angles to the frame profiles 3 and attached to it. The structure profiles 4 each consist of Cross-section essentially U-shaped, closed on three sides, the limit the individual segments 2 laterally. As can be seen from Fig. 6a exist the structural profiles 4 each from two lateral legs 5 and one these connecting web 6. Between the adjacent structure profiles 4, each with a leg 5 facing one another, there is a core layer 7, the thickness of the distance between the two legs 5 of a structural profile 4 corresponds. A particularly good heat and sound insulation with one at the same time, sufficient dimensional stability of the individual segments 2 Formed panel elements 1 is achieved in that as a material for the Core layer 7 an open-pore lightweight concrete is used. The concentration and / or composition of this lightweight concrete of the core layers 7 of the Segments 2 will depend on the purpose of the individual panel elements customized. Since the use of the panel elements 1 as building exterior wall elements, Building or apartment partition elements or Ceiling elements have different requirements for the forces to be absorbed or moments as well as the necessary thermal and acoustic insulation the density of the outer walls of the building is the lowest, since here in particular one good insulation is required. The through a particularly large pore Design of the lightweight concrete caused low density particularly good thermal insulation. The inside of a building as well particularly important when building exterior wall-to-building wall Sound insulation is due to a large mass and thus a high density of the Material of the core layer 7 reached. The density of the material of the core layer 7 of the panel elements used as ceiling elements lies between the Density of the building's outer wall elements and that of the building or Party wall elements.

As can further be seen from FIG. 2, are in this first embodiment the structure profiles 4 between two adjacent to each other Segments 2 with mutually facing webs 6 at a distance from one another arranged, the between the webs 6 facing each other Structural profiles 4, a support space 8 is formed. In particular, only panel elements used as wall elements due to normal forces 1 is the same material as the material for filling the support spaces 8 used, which is also used to form the core layer 7.

1 and 2 it can also be seen that the panel element 1 on both sides is provided with a cover layer 9, which in addition to fire protection another Can have insulating effect.

In Fig. 3 is a longitudinal section through a panel element designed as a ceiling element 1 shown. Because ceiling elements in particular on the bending stress and are therefore exposed to a moment load, the necessary dimensional stability of these panel elements 1 when using Lightweight concrete as a material for the core layer 7 can be achieved in that the support rooms 8 are filled with normal concrete, in the prestressed reinforcing iron 10 are arranged. Otherwise the structure of the as Ceiling element used panel element 1 the structure of that shown in Fig. 2 Panel element 1, which is used as a wall element.

The structure of a supporting structure profile 4 can be seen particularly clearly from FIG. 6a. With this figure, in particular, is the formation of the structure profile 4 as a three-sided closed U-shaped profile with two legs 5 and one this leg 5 connecting web 6 can be seen. The structural profile 4 points on the legs 5 and the web 6 in the form of the three sides Space-shaped indentations 11 on both sides with undercuts 12 are dovetail-shaped.

The connection of individual panel elements 1 as a wall-ceiling connection point or wall-to-wall connection point takes place via connection profiles 13 and 14, as can be seen in Figures 4 and 5. Fig. 4 shows schematically the design of a wall-ceiling-wall junction. The U-shaped profile shown in FIG. 6c serves as the connecting profile 13, whose legs 13a are curved outward and a distance from one another, which is greater than the width of the panel elements 1 along longitudinal side frame profiles 3. As can be seen from Fig. 4, takes place the connection of a ceiling element with two wall elements in that a connection profile on the opposite sides of the ceiling element 13 is arranged such that the free legs 13a of the Show away the ceiling element. The connection profiles open upwards or downwards 13 serve to accommodate those completed with the frame profiles 3 Wall elements. The legs 13a form a lateral guide for the frame profiles 3 of the wall elements, the easy alignment of the Allow wall elements with respect to the ceiling element. For connection the wall elements with the ceiling element as well as a relative movement to prevent the frame profiles 3 to the connecting profile 13 is between the connecting profiles 13 and the frame profiles 3 a mortar layer 15 arranged.

The right-angled connection of two designed as wall elements Panel elements are shown in Fig. 5. The butt faces of the right angle wall elements to be connected to one another are each by a Butt plate formed open structure 4. The one shown in FIG. 5 Embodiment are the free legs 5 of the open to the butt surface Structural profiles 4 shortened so that in the legs 5th formed indentations 11 only one undercut 12, namely which have undercut 12 close to web 6. A particularly durable one Connection of two wall elements to be connected at right angles takes place in that in addition to filling in the open by the two Structural profiles 4 formed space in the area of the joint surface with lightweight concrete the structural profiles 4 each have two connecting profiles designed as clamping profiles 14 are interconnected. These connection profiles 14 engage the undercuts 12 of the indentations close to the web 6 11 of the adjoining legs 5 of the structure profiles 4. Such Design of a wall-wall connection point enables an exact right-angled connection of two wall elements and prevents mutual Moving the wall elements connected in this way. The design of a connecting profile 14 is particularly clear Figure 6d.

7 shows a second exemplary embodiment for designing a self-supporting panel element 1 shown. A comparison with the 2 shows that in this second Embodiment, the core layer 7 is constructed in multiple layers. In the illustrated For example, there are the core layer layers lying against the cover layers 9 7a made of normal concrete or lightweight concrete, both core layer layers 7a not must consist of the same material, and the core layer layer 7b consists of a filler, for example an insulating material. Another The difference to the panel element 1 according to FIG. 2 is that the Structural profiles 4 were rotated by 90 ° so that they were open Sides of the cover layers 9 are facing.

A composite system designed in this way for construction purposes with self-supporting Panel elements 1 thus enables simple and inexpensive Way a production of the Panel elements 1, being in addition to an adjustment to the size and function of the individual panel elements 1 also an adjustment with regard to the required mechanical stress as well as heat and noise insulation is possible.
