- FIG. 5 shows an illustration which is similar to the illustration in FIG. 4, but wherein reference symbols are drawn in with a different emphasis;
- FIG. 6 shows a snapshot during the stripping of the inner wall formwork, in a section like FIG. 4 or 5, but now reversed.
- Fig. 1 is intended to give an overview of how an overall formwork is constructed using formwork panels according to the invention and which main components such an overall formwork has.
- panel (s) In the area between the center of the drawing and the left edge of the drawing, you can see the back of six interior wall cladding panels 2 placed side by side. For the sake of brevity, these are referred to below as "panel (s)".
- the panels 2 stand with their lower end on a concrete surface 4, for example the floor slab or the basement ceiling of the building to be constructed.

- the third extension 94 is dimensioned such that its front side pointing to the left is in alignment with the front sides of the end profile 40 and the panel 2.
- the surface of the third extension 94 pointing to the right in FIG. 5 is referred to as the seventh surface 96.
- the receiving area 59 is delimited by the fourth extension 98, which extends from top to bottom in FIG. 5. Its surface pointing to the left is referred to as third surface 100.
- the vertical surface 49 of the step 45 is closely adjacent to a part of the seventh surface 96, and a portion of the first surface 90 is closely adjacent to a portion of the third surface 100.
- the sixth extension has a downward-facing fifth surface 93.
- the end profile 50 of the ceiling formwork support 18 has a first extension 65 protruding to the left at the top.
- the extension 65 sits in a step 102 of the upper leg 63 in such a way that the upwardly pointing front of the leg 63, the upwardly pointing front of the first extension 65 and the upwardly facing front 3 of the ceiling formwork panel 18 are aligned with one another.
- the end profile 50 also has a second extension 67 pointing to the right, the rear end surface of which is pointing downwards and is referred to as the second surface 104.
- This second surface 104 sits on top of a sixth surface 105, which is provided on a horizontal part of the upper side of the wall 106 delimiting the receiving area 59 at the top.
- the second extension 67 is beveled at the top in the sense that it is smaller in the vertical direction at the right, free end than at the left end.
- the end profile 50 sits with its lower end area including the second extension 67 in a channel-like receiving space between ribs 108 of the transition profile 60 and the immovable claw 75 of the connecting lock 70 on both sides.
- the latter is connected to the carrier 14 with a connecting lock, which is designed like the connecting lock 70 shown.
- This connecting lock engages the described inclined surface of the second extension 76 and an inclined surface of the carrier 14, so that the closing profile 50 and the carrier 14 there clamped together and at the same time the connecting lock against the closing profile 50 and the carrier 14, with these parts being aligned with one another, is pulled.
- FIG. 6 in which the right and left are interchanged in comparison to FIGS. 4 and 5) the stripping of the wall formwork panel 2 is illustrated.
- the connection lock 70 has been dismantled. Since the panel 2 stands up on the surface 4 below and since the first surface 90 of the end profile 40 rests against the third surface 100 of the fourth extension 98 of the transition profile 60, the panel 2 cannot simply be pulled away from the poured concrete wall in the horizontal direction as a whole.
- the panel 2 in a first phase the panel 2 is first pivoted relative to the transition profile 60 (and the concrete wall 112) by exerting a tensile force away from the concrete wall 112 in the lower region of the panel 2.
- the virtual pivot axis during this pivoting movement is the edge 110 drawn in FIG. 5 between the vertical surface 49 and the upper surface 114, this edge 110 being supported against the seventh surface 96. Since the edge 110 is positioned higher than the rest of the step 45 and the left wall 43, the pivoting movement can be performed without any part of the panel 2 digging into the concrete wall 112.
- the pivoting movement leads to an increase in the play between the surfaces 90 and 100 in this quasi-contact area, not to a reduction in the play.
- the lower edge of the panel 2 moves on a circular path around the edge 110, the bottom surface 4 practically being a horizontal tangent to this circular path.
- the edge 110 can, but does not have to, slide down a little on the seventh surface 96, since the lower edge of the panel is already away from the concrete wall 112 for a piece of a circular arc.
- a second phase the pivoting of the panel 2 is continued until there is enough free space between the lower edge of the panel 2 and the surface 4 to completely remove the panel 2 from the concrete wall 112 and the transition profile 60 in the direction to the bottom left in FIG. 6.
- the pivoting movement can be combined with a translational movement of the panel 2.
- edge 110 passes the edge 116 at the transition between the seventh surface 69 and the lower end surface of the third extension 94 and that the virtual pivot axis is then formed by the edge 116, supported against the surface 114.
- the virtual pivot axis is formed by the edge between the third surface 100 and the lower end surface of the fourth extension 98, supported against the first surface 90.
- the protruding area 57 of the end profile 40 forms a type of joint head that sits in the receiving area of the transition profile as a type of joint socket. Until there is sufficient free space available to completely remove the panel 2, the seventh surface 96 and the third surface 100 grasp the protruding area 57 from two opposite sides so that the panel 2 cannot perform any uncontrolled, unwanted movements with its upper area.
