Definitions

• the invention relates to a preferably statically load-bearing large-format component, in particular a lightweight component, in particular for creating or covering rooms in a building or for producing hollow bodies or plate-shaped or frame-shaped furniture elements, and for covering surfaces in the vertical and Civil engineering.
• a component which has two cover plates placed at a parallel distance, in the space between which one or more profile plates are arranged, which are attached to the outer cover plates, for example by gluing, screwing, soldering or welding are attached.
• the profile which can be a sheet pile or triangular profile, for example, runs parallel to the cover plates and should thereby gain part of the structural properties of the component.
• the one planned over the entire width of the profile plate Attachment to the cover plates should also result in high torsional rigidity and high resilience.
• the known component experiences a further part of the static properties in that the cavities between the profile plates and the cover plates are filled with a hard foam material, for example made of vernikulite or pearlite.
• the hard foam is intended to embed the cross struts of the profile plate so that they can no longer evade under load.
• the production of the known component is very labor intensive and difficult.
• a clamping device for the cover and profile panels is required.
• the foam material is filled into the cavities between the cover plates and the profile plates by pouring or pressing.
• the complete, void-free filling of the cavities can only succeed if the cavities have very large cross sections, but this is not the case with normal-size components of conventional dimensions. Accordingly, the known building board cannot be manufactured in a practical manner. It is also too heavy due to the many individual parts from which it is constructed. In addition, there are too many sound and heat conducting bridges in the known building board.
• the object of the invention is to provide a component with a relatively low dead weight, which is preferably designed to be statically load-bearing and inexpensive, and is easy to manufacture and handle and can ensure high sound and heat insulation.
• FIG. 1 shows a perspective illustration of a component according to the invention
• Fig. 2 shows schematically the shape of different profile strips
• 3 schematically, an end view of a support structure perpendicular to the longitudinal extent of the profiled strips
• Fig. 4 shows schematically a profile strip with an integrated empty tube

• the profiled strips 4 are connected to one another, so that a manageable support frame 2 is formed which is constructed from a plurality of connected profiled strips 4.
• the profiled strips 4 are preferably fastened to one another by intermeshing short slots 7, which are introduced into the profiled strips 4 perpendicular to the respective longitudinal edge 5 at the crossing points 6, with opposing slots 7 are provided and the profile strips 4 abut each other in the slot base. Simplified, this type of connection can also be carried out with only one slot 7 in the longitudinal edge 5 of one profile strip 4, while no slot is introduced in the opposite longitudinal edge 5 of the other profile strip 4. The slot base of the one slot 7 then sits directly on the longitudinal edge 5 of the other profile strip 4 (not shown).
• the scaffolding 2 according to the invention can be compressed or stretched like an accordion in the scaffolding plane in the profile direction and bendable about an axis arranged perpendicular to the scaffolding plane, so that it can be adapted to different plate dimensions, such as plate length and plate thickness, by stretching or compressing.
• a bend can be useful, for example, for a plate to be shaped accordingly.
• the support frame 2 can, however, also be bent out of the plane of the frame plate, so that, for example, a cylindrical shell, spherical shell or wave shape or the like can be bent or bended, the bend being both about a profile direction and is also possible about an axis extending perpendicular to the profile direction.
• the support structure 2 is preferably made in the dimensions of a wall. However, it can also be composed of partial support structures stacked on top of one another in the width direction and / or placed one on top of the other in the profile direction, for example modular.

• the bars 12, 14 are placed against the profiled strips 4 from the broad side of the supporting structure and arranged in a stationary manner.
• the number of stiffening elements 8, 9, 11, 12, 14 depends on the degree of stiffening desired.
• a further embodiment of the invention provides for empty tubes 16 for installations in the profile direction of the profile strips 4 to be arranged through corresponding holes, these empty tubes 16 also stiffening the profile strips 4 when the tubes 16 engage positively through the holes (FIG. 4).
• the Support frame 2 arranged in the space between a formwork and then poured a building material in pourable consistency into the interior of the formwork.
• the building material is allowed to harden, which results in the finished structural component.

• production can also take place by first pouring the pourable building material into the formwork mold and then immediately pressing the support structure 2 into the fresh building material mass.
• the building material mass then hardens to the building material body 3.
• a heating medium for example warm air or superheated steam, can be passed through the pipes to support the drying and / or hardening of the building material, so that the time for the completion of a component according to the invention can be shortened considerably.

• the profiled strips 4, but also the stiffening elements 8, 9, 11, 12, 14 can expediently have numerous holes 19 which are penetrated by building material, so that the support structure 2 and, if appropriate, also the stiffening elements in the material body 3 in the manner of a rivet is anchored. Furthermore, knobs, beads or similar projections or depressions can be provided for the same purpose (not shown).
• the surface of the profile strips 4 can also be roughened if necessary. It is also advantageous to perforate the profiled strips 4 with many fine holes through which no building material can penetrate because they are too narrow.

• the webs projecting back and forth due to the intersecting longitudinal edges of the bands 4 in the transverse direction of the bands are spatially distributed such that they act as anchor elements in the building material and hold the supporting structure 2 immovably in the building material body 3, which results in a particularly favorable cooperation between the building material and the support structure 2 in relation to the inherent strength of the component results. If an appropriate building material is used, the mobility and / or elasticity of the supporting structure can largely be retained and thus become a property of the component.
