(7) A view of an embodiment of a wall construction panel 1 according to the invention is represented as a schematic diagram. It can be recognized in FIG. 1 that the wall construction panel 1 comprises a pillar element 2, an edge element 3 and two framework elements 4 as four frame elements, wherein the pillar element 2 and the edge element 3 extend in the vertical direction Y and the framework elements 4 in the horizontal direction X. The four frame elements 2, 3, 4 thus form a rectangular frame that encloses a panel 5. This being, the pillar element 2 and the edge element 3 are connected with each other by the framework elements 4. The eccentric screws 73 of the eccentric clamp connectors 7 that are inserted in hollow profile areas of the framework elements 4 can be seen in FIG. 1, whereby this is represented in more detail in FIG. 5. The pillar element 2 is connected to respectively one of the framework elements 4 by respectively one eccentric clamp connector 7, wherein the connection is performed in that the eccentric clamp connector 7 is clamped by the eccentric screw 73 and widens in the groove of the pillar element 2 that is undercut. Moreover, two screws 63 with which respectively the first holding section of respectively one connecting element 6 is screwed to the edge element 3 can be seen in FIG. 1, this being represented in more detail in FIG. 4. Furthermore, it can be recognized in FIG. 1 that the pillar element 2 has a receiving groove 20 that extends in the drawing plane. A further wall construction panel can be connected with the pillar element 2 of the represented wall construction panel 1 with this receiving groove 20 for implementing a wall.

(8) An exploded view of a section of the edge element 3 and of the connecting element 6 of the embodiment according to FIG. 1 is schematically represented in FIG. 2. It can be recognized in FIG. 2 that the edge element 3 has two side walls 30 that are connected with each other by forming the U-shape of the edge element 3. Furthermore, it can be recognized in FIG. 2 that a side wall 30 of the edge element 3 has a through-hole 33. The connecting element 6 has a cross-section configured as a T-shape perpendicularly to the horizontal direction X. The connecting element 6 is represented in more detail in FIG. 3. It can be recognized in FIG. 2 that the connecting element 6 can be inserted between the side walls 30 of the edge element 3 in such a manner that the bore 66 is aligned with the hole 33 so that the screw 63 can be screwed through the hole 33 into the inner thread that is provided in the bore 66 for fixing the connecting element 6 with the edge element 3. Moreover, it can be recognized in FIG. 2 that the connecting element 6 has a fixing bore 65 into which a fixing screw 64 can be screwed for pressing the connecting element 6 with an associated framework element 4.

(9) The connecting element 6 used in the embodiment according to FIG. 1 is schematically represented in detail in FIG. 3. It can be recognized in FIG. 3 that the connecting element 6 has a T-shaped cross-section perpendicularly to the horizontal direction X. The T-shape of the connecting element 6 is formed from a base beam 61 and a crossbeam 62. The base beam 61 has a section in which the bore 66 is placed into which the screw 63 is screwed. Starting from this section, the thickness of the base beam 61 reduces in the vertical direction Y towards the crossbeam 62 (upwards) over a step, wherein this thickness reduces over the step. The crossbeam 62 has a stepped extension that is formed by the steps between the central section 620 and the two lateral sections 621, 622. The base beam 61 leads into the crossbeam 62 at the level of the central section 620. The fixing bore 65 in which the fixing screw 64 is placed is provided in the central section 620 and is placed in the vertical direction Y above the step of the base beam 61 and in the transverse direction Z in sections at the level of this step.

(10) FIG. 4 schematically shows the function of the connecting element 6 that is represented in detail in FIG. 3. The framework element 4 associated to the connecting element 6 is represented purely schematically in FIG. 4. A cutout of the edge element 3 is also represented purely schematically in sections in FIG. 4. Thus, for the sake of simplicity, the hollow profile area of the framework element 4 is represented in FIG. 4 but not a clamp connector placed in the hollow profile area. And also for the sake of simplicity, the connection of the side walls 30 of the edge element 3 is not represented in FIG. 4. However, it can be recognized in FIG. 4 that the connecting element 6 is placed with its first holding section that is configured as base beam 61, between the side walls 30 of the edge element 3 and is screwed with one of the side walls 30 by the screw 63. Furthermore, it can be recognized in FIG. 4 that the maximal width of the edge element 3 in the transverse direction Z is lower than the minimal width of the groove of the framework element 4 in the transverse direction Z. The edge element 3 is placed with a vertical section in the groove of the framework element 4, namely between the undercut sections 41, 42. The connecting element 6 is placed with its second holding section, that is configured as crossbeam 62, in the groove of the framework element 4, wherein the central section 620 is placed in the groove opening between the undercut sections 41, 42 and the lateral sections 621, 622 bear on the two undercut sections 41, 42 inside the groove. The fixing screw 64 is pressed against the bottom of the groove that is opposite the groove opening so that the fixing screw 64 presses the lateral sections 621, 622 against the undercut sections 41, 42. The connecting element 6 is thus very firmly fixed in the groove of the framework element 4 with its second holding section that is configured as crossbeam 62. A very solid fixation of the framework element 4 to the edge element 3 is thus ensured by the connecting element 6.

(11) A cutout of the embodiment according to FIG. 1, namely the lower corner on the right represented in FIG. 1, is represented in FIG. 5. The edges that extend in elements and that are not visible in the top view are represented in FIG. 5 as dashed lines. It can be recognized in FIG. 5 that an eccentric clamping connector 7 is placed in the hollow profile area of the framework element 4. The eccentric clamping connector 7 is placed with a connecting body 72 in the hollow profile area and projects with a clamping body 71 in the horizontal direction X beyond the framework element 4. Furthermore, the eccentric clamping connector 7 has an eccentric screw 73 with which the clamping mechanism of the clamping body 71 is actuated so that the clamping body 71 widens. Moreover, it can be recognized in FIG. 5 that the edge element 3 extends with its first horizontal section 31 between the framework elements 4 and thus extends horizontally along the framework elements 4 while it projects with its second horizontal section 32 in the horizontal direction X over the framework elements 4. The edge element 3 is, as explained above, connected by the connecting element 6 with the screw 63 and with the fixing screw 64 to the framework element 4. The wall construction panel 1 according to FIG. 1 can thus be joined to a further wall construction panel and connected therewith while the second horizontal section 32 is inserted into a receiving groove of the pillar element 2 of this further wall construction panel 1 and simultaneously the clamping body 71 of the eccentric clamping connector 7 is inserted into this receiving groove. A fixation between the framework element 4 and the further wall construction panel 1 or the pillar element 2 of the further wall construction panel 1 can be performed by the eccentric clamping connector 7 while the edge element 3 provides an additional fixation between the two wall construction panels 1 thanks to a second horizontal section 32 engaged into the receiving groove of the pillar element 2 of the further wall construction panel 1.

(12) It results from the foregoing that the wall construction panel 1 according to the invention is very easily built up and can be implemented at low costs. Due to the interaction of its components, the wall construction panel 1 according to the invention simultaneously has a sufficiently high stability so that several wall construction panels 1 can be connected to each other without causing any damage to the wall construction panels 1. Moreover, the several wall construction panels 1 can be solidly fixed with each other, as it has been described.
