DESCRIPTION Panel element for the production of flat building units

The invention relates to a panel element for producing flat building units of a building, with at least two panels arranged parallel to one another by means of spacers. Such panel elements are intended in particular for the construction of cost-effective prefabricated houses.

&iacgr;&ogr; A plate element for producing flat construction units is known from German utility model 297 03 032.9. In this plate element, two plates arranged parallel to one another are connected by means of profile elements made of sheet metal, which have two outer U-shaped profile sections, each comprising two legs, and an inner intermediate section connecting the two outer profile sections. To connect the plates, they are arranged with a first narrow side in one of the U-shaped profile sections so that they are clamped under tension. The opposite second narrow sides of the plates are correspondingly clamped in the U-shaped profile sections of a second profile element. Two such plate elements can be connected to one another via a strip-shaped connecting element, wherein the connecting element is arranged with a first long side in the inner, also U-shaped profile section of the first plate element and with a further long side in the intermediate section of the profile element of the second plate element so that it is clamped under tension.

The disadvantage of this known panel element is that the production of the profiled sheets is complex and an undesirable loosening of the clamping connection between the sheets and the panels can occur if the panels, which are in particular mineral-bonded chipboards, shrink due to the effects of heat and the resulting loss of moisture.

Furthermore, the sheets are susceptible to corrosion, especially on non-galvanized cut edges and when cement chipboard is used, which can make the panel elements unsightly. In addition, the profile elements add bulk to the outside of the panels. However, countersinking the sheets is complex and can also lead to stability problems due to the increased density of the panels outdoors.

Furthermore, a plate element of this type is known from German utility model 297 18 999.9 or from the published specification of German patent application 197 47 129.3. In this plate element, the spacers are arranged in the narrow side area between two plates in such a way that the spacers form a U-shaped groove together with the plates on one narrow side and a complementary tongue on the opposite narrow side.

Due to the different narrow sides, this panel element cannot be used in some areas of a flat construction unit without modification. For example, the spring must be cut off if the panel element is used to limit a door or window recess, or a special panel element must be manufactured for such areas. In addition, with this known panel element there is a risk that the spring will be damaged during transport of the panel element.

The invention is therefore based on the object of providing a generic plate element which can be used as a basic element in as many different ways as possible.

This object is achieved by the features of claim 1. By means of an external spring, the plate element can be connected to another such plate element by the external spring engaging in opposing grooves of the two plate elements under tension. Due to the fact that the spacers are in two

opposite edge regions of the panel element are arranged between the panels in such a way that together with the panels they form a groove extending along a narrow side, both opposite narrow sides are essentially identical. The panel element can thus also be used to delimit a door or window recess, with a filler strip that is flush with the panels preferably being inserted into the existing groove. The panel element according to the invention can also be used in corner connections, if necessary together with a filler strip.

The spacers can be strips or blocks arranged at a distance from one another. The spacers are preferably rectangular or square in cross-section. In this way, the groove formed is U-shaped. The blocks used as spacers can also be round, oval or star-shaped with square or rounded edges.

Additional spacers can be arranged in the space between the groove areas.

The spacers are preferably connected to the panels by means of U-shaped clamp elements. Screws, dowels or bolts can also be used as connecting elements, or the spacers can be attached by gluing.

The cavity or cavities between the panels and the spacers can be designed in such a way that heat and/or sound insulation material and/or a vapor barrier can be arranged in them or that sand or flowing concrete can be filled into the cavity. The concrete can be flowing concrete, in particular lightweight concrete. The lightweight concrete can be provided with fine aggregates such as pumice, blast furnace slag, brick chippings, polystyrene, perlite, Styrofoam in the form of small particles or beads.

The boards can be mineral-bonded chipboards, particularly cement chipboards, gypsum-bonded boards or wood boards. The spacers can also be made of these materials. The boards and spacers are preferably made of the same material in order to ensure that the differences in behavior during changes in temperature and humidity are as small as possible.

The external spring provided for connecting the plate element to another such plate element, which engages with a first side in a groove of the plate element and with a second, opposite side in a groove of the further plate element in a clamping manner under tension, is preferably designed in the form of a strip. In this case, it can extend with one long side within the entire length of the groove of the plate element and with the opposite long side within the entire length of the groove of the further plate element. The external spring can be made of the same material as the plates and the spacers.

A plate element according to the invention can also have more than two plates arranged parallel to one another. In this case, the number of grooves and external springs used on each narrow side is preferably increased accordingly.

By connecting the panel elements according to the invention as described, flat construction units such as walls, floors and roofs can be produced in a simple and variable manner. Since the panel elements, unlike the panel elements according to the German utility model 297 03 032.9, are not manufactured on the construction site of the building to be constructed, they can be subjected to a load test before being transported to the construction site.

The invention is explained in more detail below using three exemplary embodiments, with reference to the drawings.

Fig. 1 is a schematic, perspective partial view of two interconnected plate elements,

Fig. 2 is a schematic plan view of a part of three interconnected plate elements, two of which form a corner connection, and

&iacgr;&ogr; Fig. 3 is a plan view of a plate element having a groove on all four narrow sides.

The two plate elements according to Fig. 1 are designated by the reference numerals 1 and 2. They each have an outer plate 2 and an inner plate 3. The plates 2 and 3 are connected to one another by spacer strips 4 and 5. The spacer strips 4 and 5 extend in the region of the vertically extending narrow sides 17, 18 of the plate elements 1, 1' and are connected to the plates 2, 3 by connecting elements in the form of clamps 6. In Fig. 1, only the clamps 6 are shown, which extend from the inner plates 3 through the spacer strips 4, 5 into the outer plates 2. Furthermore, further clamps are provided, which extend from the outer plates 2 through the spacer strips 4, 5 into the inner plates 3. These further clamps are arranged slightly offset in the vertical direction from the clamps 6 shown. The clamps 6 are fired in by means of compressed air in such a way that their crossbar is arranged slightly below the outside of the plates 2, 3, and the resulting depression on the outside of the plates 2, 3 is filled with a cement dust mixture containing an elastic adhesive.

The spacer strips 4, 5 together with the plates 2, 3 form a groove 7 or 8 on each vertical narrow side 17, 18 of the respective plate element 1, 1', which extends over the entire length of the narrow side 17, 18 of the

Plate element 1,1' extends. The two plate elements 1,1' are connected to one another via an external spring 9, one half of which is clamped within the groove 8 of the plate element 1 and the other half is clamped within the groove 7 of the plate element 1'. Expansion joints 15 and 15' are provided between the plate elements 1,1' and between the external spring and the spacer strips 4, 5.

The three plate elements shown in Fig. 2 are designated by the reference numerals 10, 10' and 10". Components that correspond to components shown in Fig. 1,

Ø are designated by the same reference numerals. The plate elements 10 and 10' are connected to one another, as in the connection shown in Fig. 1, by means of an external spring 9 which is arranged in a clamping manner under tension in the grooves 7 and 8 of the plate elements 10' and 10, an expansion joint 15 being provided between the narrow sides 17 and 18. The spacer strips 4, 5 are connected to the plates 2, 3 by clamps 6, 6', as in the plate elements 1, 1', the clamps 6 being shot into the outside of the inner plate 3 and extending into the outer plate 2, and the clamps 6' being shot into the outer plate 2 slightly offset in the vertical direction and extending into the inner plate 3.

The third plate element 10" is arranged at a right angle to the plate element 10' and rests with the outside of the inner plate 3 against a narrow side 18 of the plate element 10' in such a way that a narrow side of the plate element 10" is flush with the outside of the outer plate 2 of the plate element 10'. The plate elements 10' and 10" are connected to one another by means of a screw 11 which extends through the outer plate 2 of the plate element 10", the spacer strip 4, the inner plate 3 and through the unfilled groove 8 of the plate element 10' into its spacer strip 5. In addition, these two plate elements are connected to one another by means of an angle iron 12 which is fastened to the outer plate 2 of the plate element 10" and to the outer plate 2 of the plate element 10' with screws 13.

The angle iron 12 closes the groove 7 so that it is not visible and therefore does not need to be filled with a filling strip.

In contrast, the groove 7 of the plate element 10 is filled by a filling strip 16 which has half the width of the external spring 9 and thus ends flush with a narrow side 17 of the plate element 10. Such a narrow side is provided to delimit a window or door recess in a wall.

The cavities 14 between the spacer strips 4, 5 of the panel elements 10, 10', 10" are preferably filled with a material. This material can be sand, for example. Sand increases the impact resistance of the panel elements 10, 10', 10" by transferring the forces of an impact exerted on the inner panel 3, for example, to the outer panel 2 through the sand, and thus both panels 2, 3 absorb the forces. In addition, the sand makes the noise generated by an impact more similar to the corresponding noise in a solid house.

The plate elements 10, 10', 10" are arranged with their lower narrow side in a U-profile rail (not shown) which is fastened to, for example, a strip foundation in such a way that its legs extend vertically from the foundation. The U-profile rail can have a drip plate on the side that rests against an outside of a house wall, which prevents rainwater from penetrating between the foundation and the U-profile rail. The upper narrow side of the plate elements 10, 10', 10" is also arranged between the legs of another U-profile rail (not shown), which extends over several plate elements and thereby gives the plate elements stability in the transverse direction.

The corner joint shown in Fig. 2 is assembled in the following way. First, the plate element 10" is attached to the plate element 10' with the screw 11. Then the angle iron 12 is attached to the

Screws 13 to the plate 2 of the plate element 10" and then to the plate 2 of the plate element 10'.

The panel element 19 shown in Fig. 3 has four spacer strips 20 which are arranged in the edge regions of the panel element 19. The spacer strips 20, which do not extend over the entire length of the respective narrow side 21 of the panel element 19, are arranged in such a way that, together with the panels, one of which can be seen and is designated by the reference numeral 22, they form a groove 23 along each narrow side 21, into which a respective external spring (not shown) clamps for connection to an adjacent panel element under tension. Such a panel element 19 can be provided in particular for producing a floor.
